What to look out for
Costly issue
Inspect rubber boot for tears and check for grease contamination outside the boot.
Front lower control arm ball joint wear
Both LW and LY MPV generations develop progressive wear in the front lower control arm ball joints. The boot splits, water and grit enter the joint, and wear accelerates. Affected vehicles clunk over bumps, exhibit vague steering and suffer accelerated tyre wear. If the joint fails completely, sudden wheel tuck-under is possible. This is a common WOF failure point on older NZ-import MPVs.
What you would notice
Costly issue
A significant thickness difference between inner and outer pads on the same caliper confirms a seized pin.
Brake Caliper Guide Pin Seizure Causing Uneven Pad Wear and Brake Pull
The sliding guide pins on the front and rear brake calipers require periodic lubrication with high-temperature brake grease. When the rubber dust boots crack and allow moisture ingress, the steel pins corrode and seize within their bores, preventing the caliper from sliding freely. A seized guide pin forces one brake pad to remain in constant contact with the rotor, causing rapid and uneven pad wear on one side, premature rotor scoring, and a pronounced pull to one side under braking.
What you would notice
Common issue
Operate sliding door with the power button multiple times.
Power sliding door actuator and latch failure
LY MPV power sliding door actuators, latch assemblies and associated wiring develop faults with age and use. The actuator motor can fail to engage, the latch may not release or secure fully, and corroded wiring connectors at the door hinge flex-point cause intermittent errors. The door may refuse to operate electrically while remaining manually operable, or may fail to latch securely. Faults worsen in cold or wet conditions.

Electrical
01Electric Power Steering Rack Internal Rattle and Torque Sensor Fault
The LY-generation MPV uses an electric power steering (EPS) rack that develops an internal rattle or knock at low speeds, most noticeable on car parks and slow manoeuvres. The rattle originates from worn internal rack bearings or loose tie-rod preload within the rack assembly. Separately, the EPS torque sensor can develop a fault that causes the system to revert to full-manual steering weight without warning, triggering a power steering warning light and significantly increasing steering effort, particularly at low speed.

02Power sliding door actuator and latch failure
LY MPV power sliding door actuators, latch assemblies and associated wiring develop faults with age and use. The actuator motor can fail to engage, the latch may not release or secure fully, and corroded wiring connectors at the door hinge flex-point cause intermittent errors. The door may refuse to operate electrically while remaining manually operable, or may fail to latch securely. Faults worsen in cold or wet conditions.

Affected vehicles clunk over bumps, exhibit vague steering and suffer accelerated tyre wear. If the joint fails completely, sudden wheel tuck-under is possible. This is a common WOF failure point on older NZ-import MPVs.

012.3 DISI turbo failure from clogged oil-feed banjo filter
Can't confirm for this car
Can't confirm for this car
On the 2.3 DISI turbo MPV, the turbocharger's oil feed passes through a small banjo bolt containing a fine filter screen that clogs with carbon/sludge over time, starving the turbo bearings of oil and destroying the turbo (often with blue smoke). Using the wrong oil or stretching oil changes brings it on. A smoking or whining turbo on one of these is an expensive fix.

022.3 timing-chain stretch and rattle on cold start (S-VT)
Can't confirm for this car
Can't confirm for this car
The 2.3 (L3) engine in the LY MPV, especially the DISI turbo, is known for a timing chain that stretches with age and rattles on cold start, sometimes with a faulty variable-valve-timing (S-VT) actuator adding to the noise. If ignored, a stretched chain can jump timing and cause serious engine damage. A pronounced rattle for more than a second or two on start-up is a warning to take seriously.
Example of the part — not this vehicleThe front of a twin-cam engine with the timing cover off — chain, sprockets and guides.

03L3-DE 2.3 Ignition Coil-on-Plug Failure Causing Engine Misfires
Can't confirm for this car
Can't confirm for this car
The L3-DE 2.3-litre four-cylinder uses individual coil-on-plug ignition coils that are prone to heat-soak failure, particularly on higher-mileage examples. Cracking of the coil boot allows high-voltage arcing to the spark plug well, producing a persistent misfire on one or more cylinders that can foul the catalytic converter and trigger a P0301–P0304 diagnostic trouble code if left unaddressed.
Example of the part — not this vehicleA coil-on-plug ignition rail, removed. One coil per cylinder.

Can't confirm for this car
The direct-injection 2.3 (DISI) engine lets carbon accumulate on the intake valves because fuel no longer washes them, producing rough idle, hesitation and misfires as the miles climb. A walnut-blast clean restores it. It is an inherent design trait rather than a defect, but many higher-km MPVs have never had it addressed.

Engine, transmission & cooling
01Automatic transmission failure / harsh shifting / no reverse
Does not apply
Does not apply
The LW MPV is from the era of notorious Mazda automatic transmission trouble, with complete failures (a spike around 2002), harsh shifting, slipping and sometimes a loss of reverse gear - occasionally right after a fluid change on the 5-speed auto. A failed transmission is a major cost on a car worth relatively little. This is the make-or-break item on a used LW MPV.

02V6 overheating from tired radiator / thermostat
Does not apply
Does not apply
The 2.5 and 3.0 V6 LW MPVs commonly develop cooling weaknesses with age - a silted or leaking radiator, failing thermostat and perishing hoses - that let the engine overheat, and many NZ imports arrive with original, tired cooling parts. Overheating a V6 risks head-gasket and warping damage that dwarfs the cost of a radiator. Cooling history is worth confirming.
Example of the part — not this vehicleA double-valve engine thermostat, labelled: the wax capsule is what sticks.

Does not apply
The MPV's power sliding doors are a known trouble spot, with motors, cables, latches and switches failing so the door won't open or close on the button, or operates erratically. On a family people-mover a dead power door is a daily annoyance and repairs can be fiddly. Manual operation usually still works, but check both sides.

01Rear sliding door lower rail rust-through
Does not apply02Power Sliding Door Roller Track Wear and Corrosion
Does not apply
Does not apply
The LW MPV's power-operated rear sliding doors develop progressive wear in the upper and lower roller tracks, causing erratic door movement, mid-travel stopping, failure to fully latch, or refusal to open from the outside. The lower track is prone to trapping water and road grit, accelerating roller degradation and causing rust perforation on poorly maintained examples, particularly coastal NZ vehicles. JDM imports frequently have neglected track lubrication.
