Repair estimates are a guide for an independent garage: labour at the national median local garage rate (median £78 an hour from 65 garages, ONS price quotes) times estimated labour hours, plus a parts band. Labour hours and most parts bands are estimates, not quotes, and prices vary by model, engine and region. A warning light fault shows the cost of the diagnosis only.

What to check on a viewing

On the Lexus IS, the suspension items testers fail most are shock absorber leaking.

Listen for knocks or clonks over speed bumps and rough roads on the test drive.
Push down hard on each corner: the car should settle at once rather than keep bouncing.
Look behind the wheels for broken or heavily rusted coil springs and split rubber bushes.
Check that the car sits level and that no tyre is worn on one edge only.

Ask for the car's MOT history: a suspension advisory that repeats from year to year has not been fixed. GOV.UK MOT history.

Suspension problems on other Lexus models

Read this with care. A fail rate is not a measure of build quality. How far cars are driven, how they are used and how well owners maintain them all change it, and wear items such as tyres and brake pads are common fails. Compare a model only with cars of the same age. Methodology and limits.

The all cars figures cover all class 4 vehicles (cars and light vans) tested at the same age.
