Most Common SsangYong (KGM) SsangYong Rexton Faults & Repair Costs

Moderate Risk

4WD Vacuum Hub Failure

Est. Cost£200–£500

On older Rexton models (pre-2017), the vacuum seals in the front hubs can perish, preventing 4WD engagement.

Warning Signs:

4WD light on but only rear wheels spinning, Hissing noise from front wheels

High Risk

Fuel Injector Seizure

Est. Cost£300–£2,000+

On the 2.7L diesel (Mercedes-derived), injectors can seize into the cylinder head, making them extremely difficult to replace.

Warning Signs:

Rough running, Black smoke, "Black death" (carbon buildup) around injectors

Moderate Risk

Automatic Transmission Wear

Est. Cost£400–£1,200

The Mercedes-sourced 7G-Tronic automatic can suffer from jerky starting and hard shifting if the transmission oil is not changed regularly (every 60,000–80,000 km).

Warning Signs:

Jerky pull-away, Hard shifting between gears, Transmission warning light, Slipping gears

Low Risk

Electrical Sensor and Infotainment Faults

Est. Cost£100–£400

ABS/ESP sensors near the wheel hubs can fail due to moisture ingress, causing warning lights. The infotainment system can suffer from random reboots and Bluetooth sync issues.

Warning Signs:

ABS/ESP warning lights, Infotainment reboots, Bluetooth connection dropping, Dashboard flickering

Essential Pre-Purchase Step

Buying a used SsangYong (KGM) SsangYong Rexton? Always check for hidden finance and write-off history.

Mechanical problems are only half the battle. Over 1 in 3 UK used cars checked have unpaid finance or accident write-off records that could cause you to lose the car or thousands in value.

Inspection Checklist for SsangYong (KGM) SsangYong Rexton Buyers

Verify the towing weight on the V5C; Rextons are often bought for their 3,500kg capacity.
Check the automatic gearbox shifts; they should be smooth. Any jerking suggests a software issue or old fluid.
Inspect the interior plastics for rattles, which can develop on older models.
