What to look out for

The checks worth doing on a Toyota Vitz before you hand over any money. Every documented fault is listed below, each with its own page.

Serious issue
Check the VIN plate with the manufacturer or with Toyota NZ before purchase.
See why
Takata airbag recall - many JDM imports still outstanding
The Vitz falls inside the massive Takata airbag inflator recall that hit NZ's JDM import fleet hard - degraded inflator propellant can rupture the metal housing and spray fragments when the airbag deploys. NZ made the highest-risk 'alpha' inflators a compulsory recall, and NZTA can flag affected VINs at WoF time. The fix is free at Toyota NZ dealers, but grey imports keep arriving with the work not done, and an outstanding alpha recall can block registration.
What you would notice
- No visible symptoms - this is a latent safety defect
- Airbag warning light only if the system has a separate fault
Typically $0 to put right.
Costly issue
Inspect the rubber dust boot for cracks, tears, or missing material.
See why
Front Lower Control Arm Ball Joint Wear
The front lower control arm on the P90 Vitz uses a pressed-in or bolted ball joint at the outboard end that connects the arm to the front hub knuckle. The joint is a sealed-for-life unit and relies on its factory grease charge for the life of the component; in NZ road conditions the rubber dust boot is prone to cracking from stone strike and UV degradation, allowing moisture and grit ingress that accelerates wear of the ball and socket. A worn joint develops measurable play, degrading steering geometry and introducing clunking under load changes. At advanced stages of wear the joint can separate without warning, causing immediate loss of directional control, classifying this as a safety-critical failure mode.
What you would notice
- Clunking or knocking sound from the front suspension when accelerating, braking, or traversing rough surfaces
- Vague or wandering steering feel, especially noticeable when changing lanes on the open road
Typically $280–$750 to put right.
Costly issue
Attempt to slide the caliper manually along its pins; it should move freely by hand with light finger pressure.
See why
Front Brake Caliper Guide Pin Seizure
The front brake calipers on the P90 Vitz are sliding single-piston units in which the caliper body floats on two steel guide pins to apply equal clamping force across both brake pads. The guide pins are protected by rubber boots, and when these boots crack or degrade — a common occurrence on vehicles operating in NZ's wet coastal and alpine environments — moisture and road salt contact the pins, causing corrosion and eventual seizure within the caliper bracket bores. A seized guide pin prevents the caliper from sliding off the rotor after brake release, maintaining residual pad contact that generates heat, accelerates pad and rotor wear on one side, and causes the vehicle to pull under braking. In severe cases the stuck pad overheats to the point of brake fade or rotor warping.
What you would notice
- Vehicle pulls noticeably to one side during braking, with the pull worsening as the brakes heat up
- Uneven brake pad wear with one inboard or outboard pad significantly thinner than its partner, or left-side pads significantly more worn than right
Typically $180–$580 to put right.
Costly issue
Check the dashboard for any stored EPS warning light.
See why
Electric Power Steering Column Motor Failure
The XP90 Yaris uses a column-mounted electric power steering (EPS) unit where the assist motor and torque sensor are integrated into the steering column rather than mounted on the rack. The motor windings and associated control module are susceptible to failure, particularly in high-mileage examples or those that have experienced water ingress into the footwell. Failure results in sudden loss of power steering assist with an illuminated EPS warning light. The steering remains mechanically operable but requires substantially greater effort, which can be dangerous for drivers not expecting the change.
What you would notice
- EPS or power steering warning light illuminated on dashboard
- Sudden increase in steering effort, particularly at low speed or parking
- Intermittent return of normal steering assist then loss again
- Fault stored in EPS control module (retrievable via OBD scan)
Typically $800–$2,200 to put right.
Costly issue
Visually inspect the ABS modulator for white corrosion deposits and rust staining around the solenoid connectors and brake line unions.
See why
ABS Modulator Corrosion Causing Brake Warning Fault
The ABS hydraulic modulator unit on the NCP90 Yaris is mounted low in the engine bay and exposed to road spray. The aluminium body and steel solenoid valve bodies corrode at their interface, causing internal sealing failure. This triggers spurious ABS fault codes, illuminates the ABS and sometimes the brake warning light, and can cause the ABS system to deactivate entirely. A fully deactivated ABS system leaves the vehicle without anti-lock protection during emergency stops.
What you would notice
- ABS warning light permanently illuminated on the dashboard without any wheel speed sensor fault being present
- Brake pedal pulsing during normal braking below ABS activation threshold, indicating a solenoid valve sticking open due to internal corrosion
Typically $800–$1,700 to put right.
Common issue
Apply the handbrake and count the number of clicks before full engagement; more than 7-8 clicks is a concern.
See why
Rear Drum Brake Adjuster Corrosion & Weak Parking Brake
NCP90 and KSP90 Yaris models imported from Japan suffer extensively from corroded rear drum brake self-adjusting mechanisms. The adjuster wheel, strut, and spring corrode and seize in position, preventing the shoes from automatically compensating for lining wear. This causes excessive shoe-to-drum clearance, a weak or ineffective parking brake that may fail a New Zealand Warrant of Fitness inspection, and reduced overall rear braking performance. The condition is very common on vehicles that spent time in coastal or humid environments in Japan before import. Drum removal, adjuster replacement, and full brake shoe inspection are required to restore safe function.
What you would notice
- Handbrake lever travels very high before brakes engage, more than 8 clicks
- Vehicle rolls on a slope with handbrake fully applied
- WoF failure for insufficient parking brake holding force
- Rear brake pedal feels long or spongy compared to front
Typically $150–$500 to put right.

01Electric Power Steering Column Motor Failure

Check the dashboard for any stored EPS warning light.2005–2011Electrical$800–$2,200

OccasionalElectrical $800–$2,200 to fix

The XP90 Yaris uses a column-mounted electric power steering (EPS) unit where the assist motor and torque sensor are integrated into the steering column rather than mounted on the rack. The motor windings and associated control module are susceptible to failure, particularly in high-mileage examples or those that have experienced water ingress into the footwell. Failure results in sudden loss of power steering assist with an illuminated EPS warning light. The steering remains mechanically operable but requires substantially greater effort, which can be dangerous for drivers not expecting the change.

Symptoms to notice

EPS or power steering warning light illuminated on dashboard
Sudden increase in steering effort, particularly at low speed or parking
Intermittent return of normal steering assist then loss again
Fault stored in EPS control module (retrievable via OBD scan)

What to check

Check the dashboard for any stored EPS warning light.
Turn the steering lock-to-lock slowly at idle and note any inconsistency in assist level.
Inspect under the dashboard for signs of water ingress or moisture near the steering column base.
If a workshop inspection is possible: Scan the EPS control module with an OBD tool for fault codes C1511–C1555.

Where to look: Electric power steering motor and ECU integrated into steering column, inside cabin under dashboard

Parts involved: Steering rack.

Ask the seller

“Has the EPS warning light ever come on?”
“Have you ever noticed the steering feel suddenly heavier than normal?”
“Has any work been done to the steering column or EPS system?”

02Taillight Assembly Water Ingress and Electrical Short

Inspect the taillight lenses for visible condensation or water droplets inside the lens.2005–2011Electrical$120–$450

CommonElectrical $120–$450 to fix

The NCP90 Yaris taillight assemblies use a body-to-lens seal that degrades with UV exposure and temperature cycling. Once the seal fails, water enters the lens housing and pools around the bulb holders. This causes bulb holder corrosion, short circuits that blow fuses, and in some cases melts the bulb holder plastic. The affected light may fail entirely or flicker, and the corroded socket can cause a brake light circuit fault detectable during a Warrant of Fitness check.

Symptoms to notice

Visible condensation or standing water inside one or both taillight lenses, particularly noticeable after rain or washing
Intermittent brake light, indicator, or tail light failure that does not correspond to a blown bulb, caused by corroded bulb holder contacts creating an open or resistive circuit

What to check

Inspect the taillight lenses for visible condensation or water droplets inside the lens.
Check all rear light functions including brake, indicator, and reverse — any intermittent operation points to corroded contacts.
Inspect the body-to-lens seal (typically foam rubber) for compression set, cracking, or gaps.
If a workshop inspection is possible: Remove the taillight assembly and inspect the bulb holders for green or white corrosion on the contacts and heat discolouration on the plastic holder from arcing.

Where to look: Rear taillight assemblies, both sides, particularly lower edge where water pools

Parts involved: Body corrosion.

Ask the seller

“Have you noticed any condensation inside either taillight lens, or has a WOF inspector ever flagged a rear light fault?”
“Have any rear light bulbs needed replacing more than once, which could indicate a corroded holder causing bulb failure?”

Body, brakes, suspension & interior2 critical9

03Brake Master Cylinder Internal Seal Failure

The brake master cylinder on NCP90 models uses rubber cup seals that can deteriorate with age or contaminated brake fluid.2005–2011Brakes$400–$950

OccasionalBrakes $400–$950 to fix

The brake master cylinder on NCP90 models uses rubber cup seals that can deteriorate with age or contaminated brake fluid. Internal bypass occurs when a seal allows fluid to pass the piston, producing a pedal that slowly sinks to the floor under steady pressure even though the external fluid level does not drop rapidly. This is a safety-critical failure as braking force is progressively lost without any visible external leak to warn the driver.

Symptoms to notice

Brake pedal slowly sinks toward the floor under sustained firm pressure during a static hold test, even though no external fluid leak is visible
Brake fluid reservoir level gradually dropping over weeks without any visible leaks at callipers, hoses, or wheel cylinders, indicating internal bypass to the booster side

What to check

With the engine off, depress the brake pedal firmly and hold constant pressure for 30 seconds — any pedal sinking more than 5 mm indicates internal bypass.
Check brake fluid in the reservoir for dark brown or contaminated condition, which accelerates seal degradation.
Inspect the master cylinder body and both brake lines at the master for weeping.
Ask when the brake fluid was last flushed — the service interval is every 2 years regardless of appearance.

Where to look: Brake master cylinder on firewall, driver's side

Ask the seller

“Does the brake pedal hold firm under steady pressure, or does it slowly sink if you hold it for 30 seconds?”
“When was the brake fluid last changed and has the reservoir level ever dropped unexplainably?”

04Takata airbag recall - many JDM imports still outstanding

Check the VIN plate with the manufacturer or with Toyota NZ before purchase.petrol2005–2016Interior$0

OccasionalInterior $0 to fix

The Vitz falls inside the massive Takata airbag inflator recall that hit NZ's JDM import fleet hard - degraded inflator propellant can rupture the metal housing and spray fragments when the airbag deploys. NZ made the highest-risk 'alpha' inflators a compulsory recall, and NZTA can flag affected VINs at WoF time. The fix is free at Toyota NZ dealers, but grey imports keep arriving with the work not done, and an outstanding alpha recall can block registration.

Symptoms to notice

No visible symptoms - this is a latent safety defect
Airbag warning light only if the system has a separate fault

What to check

Check the VIN plate with the manufacturer or with Toyota NZ before purchase. If outstanding, make recall completion a condition of sale - it is free but takes a dealer visit.

Where to look: Front airbag inflators, steering wheel and passenger dashboard

Ask the seller

“Has the Takata airbag recall been completed on this exact VIN?”
“Can you show the recall completion record?”

05ABS Modulator Corrosion Causing Brake Warning Fault

Visually inspect the ABS modulator for white corrosion deposits and rust staining around the solenoid connectors and brake line unions.2005–2011Brakes$800–$1,700

OccasionalBrakes $800–$1,700 to fix

The ABS hydraulic modulator unit on the NCP90 Yaris is mounted low in the engine bay and exposed to road spray. The aluminium body and steel solenoid valve bodies corrode at their interface, causing internal sealing failure. This triggers spurious ABS fault codes, illuminates the ABS and sometimes the brake warning light, and can cause the ABS system to deactivate entirely. A fully deactivated ABS system leaves the vehicle without anti-lock protection during emergency stops.

Symptoms to notice

ABS warning light permanently illuminated on the dashboard without any wheel speed sensor fault being present
Brake pedal pulsing during normal braking below ABS activation threshold, indicating a solenoid valve sticking open due to internal corrosion

What to check

Visually inspect the ABS modulator for white corrosion deposits and rust staining around the solenoid connectors and brake line unions.
Scan for ABS codes C0200 (right front wheel speed sensor circuit) or C1241 (ABS solenoid malfunction) which can be triggered by modulator corrosion rather than sensor failure.
Check whether the ABS warning light is permanently illuminated on the dashboard.
Request previous WOF history — repeated ABS advisory notes indicate an ongoing problem.

Where to look: Engine bay, ABS modulator unit near the firewall on the driver's side

Parts involved: Body corrosion.

Ask the seller

“Is the ABS warning light currently on or has it come on in the past?”
“Has the ABS modulator been inspected or replaced, or has any workshop flagged it on a WOF inspection?”

06Front Lower Control Arm Bush Deterioration

The front lower control arm inner pivot bushes on both NCP90 and NCP130 Yaris are rubber-bonded pressed units.2005–2020Suspension$350–$750

Very commonSuspension $350–$750 to fix

The front lower control arm inner pivot bushes on both NCP90 and NCP130 Yaris are rubber-bonded pressed units. Road salt, UV exposure, and age cause the rubber to crack and delaminate from the steel sleeve. Once the bush fails, the control arm pivot point has excessive play, which alters front wheel alignment under braking and cornering loads. This is one of the most frequently replaced suspension components on these models in New Zealand workshop environments.

Symptoms to notice

Clunking or thumping from the front suspension over bumps, speed bumps, and during braking, often described as coming from the front corners
Steering wander or vague straight-line tracking that worsens under braking, caused by the control arm pivot shifting under load

What to check

On a road test, accelerate and brake firmly in a straight line and listen for a thud or clunk from the front suspension, which worsens on broken surfaces. If a workshop inspection is possible: With the vehicle on a hoist, grip each front lower control arm and attempt to move it fore-aft and vertically — any visible rubber delamination or more than 2 mm of play indicates bush failure. Check for cracking of the outer rubber visible without disassembly.

Where to look: Front subframe, inner pivot of lower control arm both sides

Parts involved: Ball joint.

Ask the seller

“Have the front lower control arm bushes ever been inspected or replaced?”
“Is there any clunking from the front suspension that the current owner has noticed?”

07Front Lower Control Arm Ball Joint Wear

Inspect the rubber dust boot for cracks, tears, or missing material.2005–2010Suspension$280–$750

CommonSuspension $280–$750 to fix

The front lower control arm on the P90 Vitz uses a pressed-in or bolted ball joint at the outboard end that connects the arm to the front hub knuckle. The joint is a sealed-for-life unit and relies on its factory grease charge for the life of the component; in NZ road conditions the rubber dust boot is prone to cracking from stone strike and UV degradation, allowing moisture and grit ingress that accelerates wear of the ball and socket. A worn joint develops measurable play, degrading steering geometry and introducing clunking under load changes. At advanced stages of wear the joint can separate without warning, causing immediate loss of directional control, classifying this as a safety-critical failure mode.

Symptoms to notice

Clunking or knocking sound from the front suspension when accelerating, braking, or traversing rough surfaces
Vague or wandering steering feel, especially noticeable when changing lanes on the open road

What to check

Inspect the rubber dust boot for cracks, tears, or missing material. Check for grease leakage around the boot. A WOF inspection should include this but boots can crack between inspection cycles — examine carefully on any vehicle over five years old. If a workshop inspection is possible: With the vehicle on a hoist, grasp the tyre at the 6 and 12 o'clock positions and attempt to rock it; any vertical play indicates ball joint wear.

Where to look: Outboard end of the front lower control arms, behind each front wheel

Parts involved: Ball joint.

08Front Brake Caliper Guide Pin Seizure

Attempt to slide the caliper manually along its pins; it should move freely by hand with light finger pressure.2005–2010Brakes$180–$580

CommonBrakes $180–$580 to fix

The front brake calipers on the P90 Vitz are sliding single-piston units in which the caliper body floats on two steel guide pins to apply equal clamping force across both brake pads. The guide pins are protected by rubber boots, and when these boots crack or degrade — a common occurrence on vehicles operating in NZ's wet coastal and alpine environments — moisture and road salt contact the pins, causing corrosion and eventual seizure within the caliper bracket bores. A seized guide pin prevents the caliper from sliding off the rotor after brake release, maintaining residual pad contact that generates heat, accelerates pad and rotor wear on one side, and causes the vehicle to pull under braking. In severe cases the stuck pad overheats to the point of brake fade or rotor warping.

Symptoms to notice

Vehicle pulls noticeably to one side during braking, with the pull worsening as the brakes heat up
Uneven brake pad wear with one inboard or outboard pad significantly thinner than its partner, or left-side pads significantly more worn than right

What to check

Attempt to slide the caliper manually along its pins; it should move freely by hand with light finger pressure. Compare pad thickness on both sides of each caliper — a significant difference indicates one pad is dragging. After a test drive, cautiously check rotor temperature by feel near the hub (avoid contact with the rotor surface); a dramatically hotter wheel indicates a binding caliper. If a workshop inspection is possible: Remove the front wheels and inspect the caliper guide pin boots for cracks, tears, or missing material.

Where to look: Front brake calipers — mounted over the front brake rotors behind each front wheel

Parts involved: Brake disc and pads.

09Rear Drum Brake Adjuster Corrosion & Weak Parking Brake

Apply the handbrake and count the number of clicks before full engagement; more than 7-8 clicks is a concern.petrol2005–2011Brakes$150–$500

Very commonBrakes $150–$500 to fix

NCP90 and KSP90 Yaris models imported from Japan suffer extensively from corroded rear drum brake self-adjusting mechanisms. The adjuster wheel, strut, and spring corrode and seize in position, preventing the shoes from automatically compensating for lining wear. This causes excessive shoe-to-drum clearance, a weak or ineffective parking brake that may fail a New Zealand Warrant of Fitness inspection, and reduced overall rear braking performance. The condition is very common on vehicles that spent time in coastal or humid environments in Japan before import. Drum removal, adjuster replacement, and full brake shoe inspection are required to restore safe function.

Symptoms to notice

Handbrake lever travels very high before brakes engage, more than 8 clicks
Vehicle rolls on a slope with handbrake fully applied
WoF failure for insufficient parking brake holding force
Rear brake pedal feels long or spongy compared to front

What to check

Apply the handbrake and count the number of clicks before full engagement; more than 7-8 clicks is a concern. Check WoF records for any brake-related advisories or failures. If a workshop inspection is possible: Remove rear drum covers if possible and inspect adjuster mechanism for corrosion, seizure, and spring integrity.

Where to look: Rear drum brakes, both left and right wheel assemblies

Parts involved: Body corrosion.

Ask the seller

“Has the vehicle passed its most recent WoF on brakes without advisories?”
“Has the handbrake cable or rear drum brake mechanism been serviced recently?”
“Do you know how long the vehicle was in Japan before being imported to NZ?”

10Front Strut Top Mount Bearing Failure

With the vehicle stationary, turn the steering wheel slowly lock-to-lock and listen for clicking, clunking, or grinding from the strut towers.2005–2010Suspension$180–$480

Very commonSuspension $180–$480 to fix

The P90 Vitz uses a MacPherson strut front suspension with a rubber-isolated strut top mount that incorporates a plain or needle thrust bearing to allow the strut to rotate with steering input. The bearing is exposed to road spray and temperature cycling, which causes the grease to wash out and the bearing surfaces to corrode and pit. When the bearing seizes or develops heavy wear the strut is unable to rotate freely, transmitting steering loads into the mount rubber and creating clunking or groaning noises. Secondary effects include increased steering effort at low speeds and accelerated wear to the strut shaft seal and damper rod.

Symptoms to notice

Clunking or knocking noise from the front suspension when driving over speed bumps or sharp road imperfections
Creaking or grinding sensation felt through the steering wheel when turning at low speed or while stationary

What to check

With the vehicle stationary, turn the steering wheel slowly lock-to-lock and listen for clicking, clunking, or grinding from the strut towers. Bounce each front corner and listen for knocking. With the bonnet open, have an assistant turn the steering while you feel for rough or notchy rotation at the top mount. Check the rubber isolator for cracks or deformation as well.

Where to look: Top of each front MacPherson strut, inside the engine bay at the strut towers

Parts involved: Shock absorber / strut.

11Rear Torsion Beam Axle Bush Collapse

Push the rear beam laterally by hand — any visible movement or clunking indicates collapsed bushes.Suspension

CommonSuspension

The rear torsion beam axle on the NCP10 and NCP91 Vitz uses rubber bushes at each mounting point to the chassis. With age and mileage these rubber elements harden, crack, and collapse, allowing the beam to move in ways it should not. This causes knocking and clunking over bumps, imprecise rear handling, and uneven tyre wear on the rear axle.

Symptoms to notice

Rear beam bush rubber deteriorates causing handling noise.
Confirm with pre-purchase inspection by a qualified mechanic

What to check

Push the rear beam laterally by hand — any visible movement or clunking indicates collapsed bushes.
Check rear tyre wear for unusual edge wear patterns.
If a workshop inspection is possible: With the vehicle on a hoist, inspect both rear torsion beam mounting bushes for cracking, deformation, or separation from the metal sleeve.

Where to look: See description

01K110 CVT Belt Judder Under Light Acceleration

Test drive at low speed (10–30 km/h) with light throttle and listen/feel for a shudder or vibration through the seat and floorpan.petrol2005–2010TransmissionCan't confirm for this car$350–$3,200

CommonTransmission $350–$3,200 to fix

Can't confirm for this car

The Toyota K110 continuously variable transmission, fitted to 1NZ-FE and 2SZ-FE automatic variants of the P90 Vitz, uses a push-belt running between two variable-diameter pulleys in a bath of dedicated CVT fluid. As the fluid degrades its friction-modifier additive package depletes, causing micro-slip between the steel belt elements and the pulley faces under the light torque loads typical of low-speed urban driving. This produces a characteristic shudder or vibration felt through the drivetrain at speeds below approximately 30 km/h. Continued operation with degraded fluid accelerates pulley surface wear and can ultimately require full CVT replacement, which is disproportionately expensive relative to the vehicle's value.

Symptoms to notice

Rhythmic shudder or vibration felt through the drivetrain during gentle acceleration from rest up to approximately 30 km/h
Hesitation or ratio-hunting sensation at low steady-state speeds in light urban traffic

What to check

Test drive at low speed (10–30 km/h) with light throttle and listen/feel for a shudder or vibration through the seat and floorpan.
Check CVT fluid condition — dark brown or burnt-smelling fluid indicates overdue change.
Confirm the transmission has no harsh hunting between ratios at motorway speeds.
Verify service history for CVT fluid changes; Toyota specifies replacement at 40,000 km intervals for severe-duty use.

Where to look: K110 CVT unit — transversely mounted in the engine bay, left side of the vehicle

Parts involved: CVT belt and pulleys.

021KR-FE Valve Stem Seal Oil Consumption

Check for blue-grey smoke at cold startup that clears within a minute of running.petrol2005–2010EngineCan't confirm for this car$450–$950

CommonEngine $450–$950 to fix

Can't confirm for this car

The 1KR-FE 1.0-litre three-cylinder engine fitted to the KSP90 Vitz is documented to suffer premature hardening and cracking of the valve stem oil seals, allowing engine oil to migrate down the valve guides and into the combustion chamber during overnight cold-soak periods. The failure mechanism is accelerated by the high thermal cycling inherent in a small-displacement three-cylinder and by infrequent oil changes that raise oxidation byproducts, causing elastomer degradation in the seals at relatively low mileages. Left unaddressed the condition causes fouled spark plugs, elevated hydrocarbon emissions, catalytic converter contamination, and steadily increasing oil top-up costs.

Symptoms to notice

Blue-grey smoke emitted from the exhaust on cold startup, dissipating after the engine reaches operating temperature
Engine oil consumption exceeding 0.5–1 L per 1000 km with no visible external oil leaks

What to check

Check for blue-grey smoke at cold startup that clears within a minute of running.
Remove spark plugs and inspect for oily carbon deposits on the electrodes.
Ask the seller for oil consumption records; consumption above 500 ml per 1000 km without any visible external leak is a strong indicator.
If a workshop inspection is possible: A compression test and leak-down test help rule out ring wear as an alternative cause.

Where to look: Cylinder head, valve guides — top of the 1KR-FE engine under the cam cover

Parts involved: Catalytic converter.

03Water pump coolant leak (XP90, 1.0 1KR-FE / 1.3 2SZ-FE)

With the engine cold, check the coolant reservoir level and look down the drive-belt end of the engine with a torch for pink staining.petrol2005–2010CoolingCan't confirm for this car$300–$700

CommonCooling $300–$700 to fix

Can't confirm for this car

XP90 Vitz engines commonly weep coolant from the water pump seal from around 100,000 km - the same pattern well documented on the equivalent Yaris. It starts as pink crusty residue and a slow level drop, and if ignored on these small-capacity cooling systems it leads quickly to overheating and, on the alloy engines, head damage. The pump is cheap and the job straightforward at any NZ workshop.

Symptoms to notice

Pink/white crusty residue below the water pump
Coolant smell after a drive
Coolant reservoir dropping between checks
Whining/grinding bearing noise from the pump area

What to check

With the engine cold, check the coolant reservoir level and look down the drive-belt end of the engine with a torch for pink staining. After the test drive, sniff for hot coolant around the bonnet shuts. Ask when the water pump and coolant were last done.

Where to look: Water pump on the drive-belt end of the engine (passenger side of engine bay)

Parts involved: Water pump.

CommonEngine $120–$380 to fix

Can't confirm for this car

The drive-by-wire throttle bodies fitted to 1NZ-FE and 2SZ-FE engines in the P90 Vitz are subject to progressive carbon and varnish accumulation on the throttle plate and bore walls, primarily sourced from exhaust gas recirculation gases and crankcase blowby vapour routed through the air intake. Because the electronic throttle plate does not pass through wide-open-throttle operation during typical light urban driving, deposits are not naturally purged and instead accumulate around the plate edges. A fouled throttle body disrupts airflow calibration against the throttle position sensor reading, causing the ECU to receive inaccurate air mass signals, which produces rough idle, hesitation, and in severe cases lean misfire faults.

Symptoms to notice

Rough or hunting idle at operating temperature, particularly noticeable at traffic lights after town driving
Hesitation or stumble on light throttle application from a standstill

What to check

With the ignition on (engine off) the plate should open and close cleanly with no sticking. Check for stored idle-related fault codes (P0505 idle control, P0506/P0507). Note whether idle quality improves after a long motorway drive. If a workshop inspection is possible: Remove the intake duct from the throttle body and inspect the bore and butterfly plate face with a torch; significant black or brown carbon deposits around the plate edge and bore walls confirm fouling.

Where to look: Throttle body mounted on the intake manifold, engine bay — connected to the air filter assembly by the intake duct

Parts involved: EGR valve.

Fluid leaks1

011NZ-FE Fuel Injector Lower O-Ring Weeping

A fuel smell that is strongest at the manifold (not from the cap or filler) is diagnostic.petrol2005–2020Fluid LeaksCan't confirm for this car$200–$550

OccasionalFluid Leaks $200–$550 to fix

Can't confirm for this car

The 1NZ-FE uses four top-feed fuel injectors sealed at the lower end with Viton rubber O-rings that seat into the intake manifold ports. With age and heat cycling these O-rings harden and crack, allowing a small quantity of fuel to weep past the seal at the manifold interface. The leak is typically minor initially but worsens over time and creates a fire risk if fuel contacts the hot exhaust manifold on the same side of the engine.

Symptoms to notice

Persistent petrol smell in the engine bay particularly noticeable after the engine reaches operating temperature and is shut down
Visible fuel staining or wet residue at the base of one or more injectors where they seat into the intake manifold, sometimes with accumulated carbon and dirt stuck to the fuel

What to check

A fuel smell that is strongest at the manifold (not from the cap or filler) is diagnostic. Clean the area with brake cleaner before inspection to make fresh weeping clearly visible. This fault is most common on engines over 150,000 km or those that have not had injectors removed during prior service. If a workshop inspection is possible: With the engine warmed up and then shut off, remove the engine cover and check around the base of each injector where it enters the intake manifold for fuel staining, wet deposits, or glistening.

Where to look: Intake manifold, lower injector O-ring seats, cylinder head side

Parts involved: Fuel injector.

Ask the seller

“Is there any fuel smell in the engine bay, and has a mechanic ever mentioned any fuel weeping around the injectors?”
“Have the fuel injectors ever been removed, cleaned, or had O-rings replaced during a service?”

01K410 CVT Belt Judder on Light Throttle

Drive the vehicle from cold, applying light throttle from rest and note any vibration through the floor or drivetrain.petrol2011–2020TransmissionDoes not apply$250–$4,000

CommonTransmission $250–$4,000 to fix

Does not apply

The K410 continuously variable transmission fitted to XP130 Yaris models with both 1NZ-FE and 1KR-FE engines is prone to belt shudder or judder during light-throttle acceleration, particularly when pulling away from rest or maintaining a constant low speed. The judder manifests as a vibration felt through the drivetrain and cabin floor, sometimes with an audible shuddering noise. The primary cause is degraded CVT fluid losing its friction-modifier properties, but worn belt or pulley contact surfaces can also contribute. Toyota issued revised CVT fluid specifications recommending Toyota Genuine CVTF FE to address this. Fluid replacement often resolves early-stage judder; advanced belt or pulley wear requires transmission overhaul.

Symptoms to notice

Vibration or shudder felt through the floor during light throttle acceleration
Shudder most pronounced when pulling away gently from a standstill
Audible juddering or chattering noise from beneath the vehicle
Symptom may reduce or disappear once CVT reaches full operating temperature

What to check

Drive the vehicle from cold, applying light throttle from rest and note any vibration through the floor or drivetrain.
Check CVT fluid condition, colour, and service history.
Confirm Toyota Genuine CVTF FE fluid has been used, not a generic substitute.

Where to look: CVT transmission unit in engine bay, driver-side front of vehicle

Parts involved: CVT belt and pulleys.

Ask the seller

“Has the CVT fluid ever been changed, and what product was used?”
“Have you noticed any vibration or shudder when pulling away from lights?”
“Has the transmission been serviced at a Toyota dealer or specialist?”

021NZ-FXE Timing Chain Tensioner Wear and Cold-Start Rattle

Cold-start the engine from fully cold and listen immediately at the front of the engine for a metallic rattling or clattering lasting 1 to 5 seconds.hybrid2012–2020EngineDoes not apply$1,200–$3,800

CommonEngine $1,200–$3,800 to fix

Does not apply

The 1NZ-FXE hybrid engine's hydraulic timing chain tensioner loses hydraulic pressure retention after extended oil service intervals or high mileage, causing the timing chain to slap against the guide on cold starts before oil pressure builds. If left unaddressed, chain wear progresses to a condition where the chain can skip a tooth on the camshaft sprocket, risking valve-to-piston contact in this interference-fit engine. The problem is strongly correlated with irregular or extended oil change intervals.

Symptoms to notice

Metallic rattling or clattering from engine front on cold start, typically clearing after 2 to 5 seconds
Chain rattle that worsens progressively over time or at higher mileages
Check Engine light with OBD codes P0016 or P0017 (cam/crank correlation fault)
Rough idle or hesitation during cold-start warm-up phase
Increased oil consumption alongside rattle onset

What to check

Cold-start the engine from fully cold and listen immediately at the front of the engine for a metallic rattling or clattering lasting 1 to 5 seconds.
Check oil level and condition on the dipstick — dark dirty oil indicates neglected service intervals that accelerate tensioner wear.
Request complete service records verifying oil changes at or below 10,000 km intervals.

Where to look: Timing chain cavity, front of 1NZ-FXE engine block behind the front cover

Parts involved: Timing chain.

Ask the seller

“Does the engine make any rattling sound in the first few seconds after a cold start?”
“Can you provide full service records showing oil change history and intervals used?”
“Has the timing chain or tensioner ever been inspected, replaced, or flagged at a Toyota service?”

031SZ-FE Head Gasket Failure

Inspect coolant in the reservoir for an oily film or brown discolouration.1999–2005EngineDoes not apply$1,200–$2,800

OccasionalEngine $1,200–$2,800 to fix

Does not apply

The 1.0L 1SZ-FE three-cylinder engine fitted to the XP10 Vitz uses an aluminium cylinder head mated to a cast iron block. The differential thermal expansion rates between these materials, combined with the engine's sensitivity to overheating, makes the head gasket a known failure point. Gasket failure typically manifests as coolant loss into the combustion chamber, combustion gases entering the coolant system, or internal mixing of oil and coolant. The small cooling capacity of the 1SZ-FE means any cooling system neglect — such as a failed thermostat or low coolant — rapidly escalates to head gasket damage.

Symptoms to notice

White smoke from exhaust, especially when engine is warm
Coolant level dropping repeatedly with no external leak
Mayonnaise-like deposits on oil filler cap or dipstick
Engine overheating, particularly in traffic or on hills

What to check

Inspect coolant in the reservoir for an oily film or brown discolouration.
Run the engine and observe exhaust for sustained white smoke.
A block tester (combustion gas checker) on the coolant reservoir is the definitive field test for a failed head gasket.
Remove the oil filler cap and dipstick and look for creamy or brown emulsified deposits.

Where to look: Head gasket between cylinder head and block, front-mounted transverse 3-cylinder engine

Parts involved: Head gasket.

Ask the seller

“Has the vehicle ever overheated or been driven when overheating?”
“Has the head gasket ever been replaced?”
“When were the coolant and thermostat last serviced?”

01NHP130 Hybrid Traction Battery Cell Imbalance and Capacity Degradation

Verify no hybrid system warning lights are present on the dashboard.hybrid2012–2020ElectricalDoes not apply$2,500–$7,500

CommonElectrical $2,500–$7,500 to fix

Does not apply

The NiMH traction battery pack in the NHP130 hybrid Yaris degrades with age and charge cycles, with individual cell modules diverging in capacity over time. As cells become imbalanced, the battery management system restricts usable pack capacity to protect the weakest cells, progressively reducing hybrid assist effectiveness and real-world fuel economy. In advanced degradation, battery warning lights illuminate and the vehicle may default to restricted ICE-only operation.

Symptoms to notice

Noticeably reduced fuel economy compared to the rated specification
Hybrid battery warning triangle illuminated on dashboard
State-of-charge gauge swings rapidly between extremes or sits persistently low
Combustion engine running continuously at low speeds where it should be off
EV-only mode unavailable or cutting out almost immediately

What to check

Verify no hybrid system warning lights are present on the dashboard.
On a 20-minute test drive including a section of urban stop-start driving, observe how frequently the combustion engine kicks in at low speed — battery degradation forces the ICE to run far more than on a healthy pack.
Request a Toyota dealer hybrid battery health report; examples older than 8 years should be treated as likely requiring battery reconditioning or replacement.

Where to look: Traction battery pack, mounted under rear seat cushion

Ask the seller

“Has the hybrid battery ever triggered a warning light or been flagged as degraded at a service?”
“Is there a current Toyota dealer hybrid battery health report available to share?”
“What fuel economy is being achieved in regular driving, and has it changed noticeably compared to when the car was newer?”

01Brake Booster Vacuum Pump Seal Failure

With engine off, pump the brake pedal 5 times to exhaust stored vacuum, then start the engine and press the pedal firmly.petrol2011–2020BrakesDoes not apply$350–$950

OccasionalBrakes $350–$950 to fix

Does not apply

XP130 Yaris models fitted with the 1KR-FE 1.0-litre three-cylinder engine use a separate vacuum pump to supplement the brake booster, as the small engine generates insufficient intake manifold vacuum for reliable brake servo operation. The vacuum pump's internal seals deteriorate over time and with heat cycles, causing a reduction or complete loss of vacuum assistance to the brake booster. Affected drivers notice a noticeably spongy or harder-than-normal brake pedal requiring significantly increased pedal effort to achieve normal braking force. The fault can worsen suddenly and poses a genuine safety risk in emergency braking situations.

Symptoms to notice

Spongy or unusually hard brake pedal feel
Greater than normal pedal force required to achieve adequate braking
Hissing noise from engine bay when pressing the brake pedal
First press of the brake pedal after startup feels noticeably different to subsequent presses

What to check

With engine off, pump the brake pedal 5 times to exhaust stored vacuum, then start the engine and press the pedal firmly. Normal operation gives a clear drop in pedal height as vacuum is restored. Inspect all vacuum hoses for cracks, splits, and secure connections.

Where to look: Vacuum pump on engine or firewall, vacuum lines running to the brake booster behind the master cylinder

Parts involved: Intake manifold.

Ask the seller

“Has the brake pedal ever felt spongy or harder than usual to press?”
“Have the vacuum lines or brake booster vacuum pump been inspected or replaced?”
“Are there any brake system warning lights or fault codes recorded?”

03Electric Power Steering Rack Rattle and Column Knock (NCP130)

The NCP130 Yaris replaced hydraulic power steering with a column-mounted electric power steering (EPS) motor.2011–2020SuspensionDoes not apply$800–$1,900

CommonSuspension $800–$1,900 to fix

Does not apply

The NCP130 Yaris replaced hydraulic power steering with a column-mounted electric power steering (EPS) motor. The coupling between the EPS motor shaft and the steering column intermediate shaft develops play over time, producing a knocking or rattle when the steering wheel is held at a small angle in corners or during parking manoeuvres. In some cases the EPS torque sensor deteriorates, causing the EPS warning light to appear and intermittent loss of power assistance.

Symptoms to notice

Knocking or rattling sound from the steering column when making small steering inputs at low speed, such as lane changes or parking
EPS warning light appearing intermittently, sometimes accompanied by momentarily heavy steering before the system resets

What to check

With the engine running (EPS active), slowly oscillate the steering wheel 5–10 degrees either side of centre and listen for a knock or rattle from the column below the dash. Check the instrument cluster for the EPS warning light (orange steering wheel icon). Pull the steering wheel gently fore-aft to feel for column shaft end-play. If a workshop inspection is possible: Scan with an OBD reader for EPS-specific codes C1511 or C1512 (torque sensor signal out of range).

Where to look: Steering column, EPS motor coupling beneath dashboard

Parts involved: Steering rack.

Ask the seller

“Has the EPS warning light ever appeared, even briefly?”
“Is there any knocking or rattling from the steering column when parking or making slow-speed turns?”
