What to look out for

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

Serious issue
Probe chassis box sections with screwdriver at welded seams and drain holes.
See why
Frame and Undercarriage Rust Perforation
Older Rexton examples — particularly pre-2010 vehicles in NZ's coastal and high-rainfall regions — develop significant rust in the ladder-frame chassis rails, floor pan, and rear body mounts. The vehicle's frame shares construction heritage with the 1990s Mercedes G-Class era and is susceptible to box-section corrosion where drain holes block. Advanced cases fail NZ WoF inspections on structural corrosion grounds.
What you would notice
- Visible rust bubbling along chassis rails
- Flaking underside rust during inspection
- Water pooling in floor area (corroded floor pan drain)
- WoF rejection for structural corrosion
Typically $1,500–$7,000 to put right.
Costly issue
Check the coolant level and condition (clean, correct colour, not oily).
See why
Cooling-system leaks risking overheating (Y200/Y250)
Cooling-system problems are a serious watch-item on the older Rexton — leaks develop around the radiator, hoses and water pump, and if the engine overheats it can cause severe damage including head-gasket failure. On a heavy 4x4 that may have towed, a tired cooling system is a real risk. Fresh coolant and a healthy pump are cheap insurance versus a cooked engine.
What you would notice
- Coolant loss / low reservoir
- Temperature gauge climbing in traffic or towing
- Sweet coolant smell
- Weeping radiator, hoses or water pump
- White exhaust or mayo in oil if head gasket has gone
Typically $500–$2,500 to put right.

Engine, transmission & cooling4

01Turbocharger wear on the 2.7 XDi diesel (Y200/Y250)

On the drive, load the engine and confirm it makes boost cleanly without an unusual whistle or a puff of smoke.diesel2003–2017EngineCan't confirm for this car$1,500–$4,000

OccasionalEngine $1,500–$4,000 to fix

Can't confirm for this car

The older Rexton's 2.7 XDi turbo-diesel (a Mercedes-derived five-cylinder) is generally robust but the turbocharger can wear or fail with age and hard use, giving power loss, a whistling/whining noise and exhaust smoke. Oil starvation from tired seals or neglected servicing is a common cause. A replacement turbo is a significant bill on a budget-priced older 4x4.

Symptoms to notice

Whistle or whine that rises with revs
Loss of power / lag
Blue or black smoke
Oil in the intake pipework

What to check

On the drive, load the engine and confirm it makes boost cleanly without an unusual whistle or a puff of smoke.
Ask about oil-change history — neglect kills these turbos.
Check the intercooler piping for oil residue.

Where to look: Turbocharger on the exhaust side of the 2.7 diesel engine

Parts involved: Turbocharger.

Ask the seller

“Has the turbo ever been replaced?”
“How regularly has the oil been changed?”
“Any smoke or whistling under load?”

02Mercedes OM602/OM664 Diesel Glow Plug Seizure

CommonEngine $300–$900 to fix

Can't confirm for this car

Glow-plug problems are common on the older 2.7 diesel Rexton; when one or more fail the engine becomes hard or impossible to start when cold, with extended cranking and white smoke until it catches. Cheap to fix if caught, but a symptom that's easy to dismiss as 'it's just cold' — and a failed glow plug can be awkward to extract if it's been left.

Symptoms to notice

Hard starting when cold
Long cranking / multiple attempts
White smoke on cold start
Rough running until warm

What to check

Start it from stone cold (ask the seller not to pre-warm it).
Note extended cranking or white smoke.
Turn the ignition to the 'wait-to-start' glow stage and confirm the light behaves normally.
Ask if the glow plugs have been replaced.

Where to look: Glow plugs in the cylinder head, one per cylinder

Parts involved: Glow plug.

Ask the seller

“Can I start it completely cold?”
“Have the glow plugs been replaced?”
“Does it struggle to start on cold mornings?”

04Automatic Transmission Solenoid Wear and Shift Quality Degradation

Test drive with full warm-up then assess shift quality through all gear ranges including kickdown.2002–2017TransmissionCan't confirm for this car$800–$4,200

OccasionalTransmission $800–$4,200 to fix

Can't confirm for this car

The Rexton's automatic transmission — a Mercedes-derived 5-speed unit on early models and a Benz W5A330 on later variants — develops solenoid pack wear and valve body sludging at high mileage, causing erratic shifts, slipping between gears, and delayed engagement from rest. Transmission fluid is rarely changed on service schedules, accelerating wear. Solenoid replacement often resolves issues; rebuilt valve bodies are needed in advanced cases.

Symptoms to notice

Harsh or delayed gear changes
Slipping between 2nd and 3rd gear
Transmission warning light
Clunk when selecting Drive or Reverse from Park
Transmission overheating in stop-start traffic

What to check

Test drive with full warm-up then assess shift quality through all gear ranges including kickdown.
Scan for transmission fault codes.
Check transmission fluid colour — brown or burnt smell indicates neglected fluid.
Ask for transmission service history.

Where to look: Transmission unit, underside centre of vehicle

Parts involved: Mechatronic / valve body.

Ask the seller

“Has the transmission fluid ever been changed?”
“Are there any gear change hesitations or slips?”
“Has any transmission work been done?”

02Mercedes-sourced automatic shift-quality complaints (Y400)

On a longer test drive assess the auto through town and open-road speeds — note any harsh shifts, hesitation or hunting.2018 onwardTransmissionDoes not apply$400–$4,000

OccasionalTransmission $400–$4,000 to fix

Does not apply

The current Y400 Rexton's most commonly cited problem is its Mercedes-Benz-sourced automatic transmission, with owners reporting harsh or hesitant shifts and occasional drivability quirks. A fluid service and software update can help, but it's the standout complaint on an otherwise solid large 4x4, so assess shift behaviour carefully.

Symptoms to notice

Harsh or clunky gear changes
Hesitation or delayed engagement
Occasional flare or hunting between gears

What to check

On a longer test drive assess the auto through town and open-road speeds — note any harsh shifts, hesitation or hunting. Check for any transmission service or software-update history. Cold and hot behaviour can differ, so drive it both.

Where to look: Mercedes-derived automatic transmission

Ask the seller

“Has the transmission had any software updates or fluid service?”
“Does it shift smoothly hot and cold?”
“Any known gearbox faults?”

032.2 D22DTF Timing Chain Tensioner Wear

Cold-start the fully cold engine and listen immediately for a metallic rattle from the front-upper engine area.diesel2018 onwardEngineDoes not apply$1,800–$3,800

OccasionalEngine $1,800–$3,800 to fix

Does not apply

The hydraulic timing chain tensioner on the 2.2L e-XDi D22DTF diesel loses clamping force at high mileage, typically above 120,000 km. Worn tensioner and guide rails allow the chain to slap before oil pressure builds on cold start, producing a characteristic 2-5 second metallic rattle. Unchecked, a slack chain can skip a tooth causing catastrophic engine damage requiring full engine replacement.

Symptoms to notice

Metallic rattling from top of engine for 2-5 seconds on cold start
Noise subsides once oil pressure builds during warmup
Rattle worsens in cold ambient temperatures
P0016 or P0017 cam-crank correlation fault codes in advanced wear

What to check

Cold-start the fully cold engine and listen immediately for a metallic rattle from the front-upper engine area.
Rev to 1500 rpm and confirm noise disappears within 5 seconds.
Inspect engine oil level and condition.
Scan for P0016 and P0017 codes.
Review service history for oil change frequency.

Where to look: Front of engine, upper timing cover

Parts involved: Timing chain.

Ask the seller

“Has the timing chain or tensioner ever been replaced?”
“What is the current mileage and full service history?”
“Does the engine make any rattling noise on a cold start?”

01AWD Rear Coupling Actuator Sensor Failure

Scan all ECU modules including transfer case and AWD controller modules for fault codes.diesel2012–2017ElectricalDoes not apply$850–$2,600

OccasionalElectrical $850–$2,600 to fix

Does not apply

The electronically-controlled rear coupling unit on the Rexton W AWD system uses a position sensor on the electromagnetic actuator to confirm engagement status. The sensor and its wiring connector are exposed to road grime and moisture ingress and are prone to failure, causing the system to report an AWD fault and default the vehicle to rear-wheel drive only. A failed actuator can also prevent the rear coupling from engaging entirely, leaving the vehicle in permanent two-wheel drive and reducing off-road safety.

Symptoms to notice

4WD or AWD warning light illuminated on the instrument cluster
AWD system disengaged — vehicle defaults to rear-wheel drive only
Transfer case or AWD controller fault codes stored in ECU
Intermittent AWD engagement on loose or slippery surfaces
Grinding or clunking when AWD coupling attempts to engage

What to check

Scan all ECU modules including transfer case and AWD controller modules for fault codes.
Inspect the rear coupling actuator wiring connector and harness for corrosion, chafed insulation, or cracked plugs.
Measure actuator coil resistance against workshop manual specification.
Verify AWD engages during a low-speed test on a loose gravel surface.
Check actuator housing for evidence of water or mud ingress.

Where to look: Rear differential and coupling unit, underside of vehicle at rear axle

Ask the seller

“Has the 4WD or AWD warning light ever come on?”
“Does the AWD system engage and disengage correctly in all modes?”
“Has the rear coupling actuator or position sensor ever been replaced?”
“Has the vehicle been used off-road in mud, water, or creek crossings?”

02Electrical faults: voltage fluctuation, infotainment and ABS/ESP sensors (Y400)

Watch the dash on start-up and during the drive for flicker or warning lights, especially ABS/ESP.2018 onwardElectricalDoes not apply$150–$1,200

CommonElectrical $150–$1,200 to fix

Does not apply

The Y400 Rexton suffers a range of electrical niggles: on-board voltage fluctuations that cause infotainment dropouts, dash flicker or spurious error codes, and ABS/ESP wheel-speed sensors that sit near the hubs and get moisture-affected, bringing the ABS/ESP warning lights on with no real underlying fault. Mostly nuisance-level but can be persistent and frustrating.

Symptoms to notice

Infotainment freezing or rebooting
Dashboard flicker or false warnings
ABS/ESP warning lights coming and going
Random error messages

What to check

Watch the dash on start-up and during the drive for flicker or warning lights, especially ABS/ESP.
Test the infotainment for freezes.
Ask whether the ABS/ESP lights have been an intermittent problem.
OBD-scan for wheel-speed-sensor codes.

Where to look: ABS/ESP wheel-speed sensors at each wheel hub, infotainment head unit, vehicle wiring/charging system

Ask the seller

“Do the ABS or ESP lights ever come on?”
“Any infotainment or electrical glitches?”
“Have any wheel-speed sensors been replaced?”

01Front upper-arm play and stabiliser-bar wear (Y400)

On the drive listen for front-end clonks over bumps.2018 onwardSuspensionDoes not apply$300–$1,500

CommonSuspension $300–$1,500 to fix

Does not apply

On the Y400 Rexton the double-wishbone front suspension tends to develop play in the upper arms after roughly 70,000-100,000 km, and the stabiliser (sway-bar) links/bushes wear quickly enough to be treated as consumables (owners report around 40,000 km service life). The result is clonks over bumps and vaguer steering. Parts are relatively cheap but affect ride, handling and WOF.

Symptoms to notice

Clonk or knock over bumps from the front
Vague or loose steering
Uneven front tyre wear
Rattle from the front on rough roads

What to check

On the drive listen for front-end clonks over bumps. Have someone rock the front suspension or check on a hoist for play in the upper arms and sway-bar links. Check front tyres for uneven wear. Budget for sway-bar links as a wear item.

Where to look: Front double-wishbone upper control arms and stabiliser-bar links/bushes

Parts involved: Ball joint.

Ask the seller

“Have the front control arms or sway-bar links been replaced?”
“Any knocking over bumps?”
“Will it pass a WOF now?”
