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 Hyundai i40, the windscreen, wiper and mirror items testers fail most are wipers not clearing screen; washers: provides insufficient washer liquid; washers: not working.

Look for chips or cracks in the windscreen, above all in front of the driver.
Run the wipers and washers: they should clear the screen without smearing.
Check that the mirrors are present, secure and not cracked.

Ask for the car's MOT history: a windscreen, wiper and mirror advisory that repeats from year to year has not been fixed. GOV.UK MOT history.

Windscreen and wiper problems on other Hyundai 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.
