Common problems

1High Likelihood

Rear subframe corrosion

May have no obvious symptoms before failure; some cars develop vague rear-end tracking, uneven tyre wear, or an MOT corrosion advisory.

How to check

This usually needs an underside inspection and cannot be judged fairly on a short drive.

Estimated Repair Cost

£3,200

2Moderate Likelihood

Timing chain stretch and cold-start rattle

A short metallic rattle for the first seconds after a cold start, sometimes followed later by rough running or an engine warning light.

How to check

Start the engine from fully cold after it has been left overnight.

Estimated Repair Cost

£2,000

3High Likelihood

Thermostat stuck open / running too cool

Temperature takes a long time to rise, heater output feels underwhelming in cold weather, and the car may start collecting emissions faults.

How to check

From cold, drive for 10 to 15 minutes at normal speeds and watch how quickly the engine reaches and holds normal temperature.

Estimated Repair Cost

£350
