How to spot it before you buy

Inspect the windscreen and all glass for chips or cracks

A chip in the driver's eyeline, or a crack over 40mm, fails the MOT (~£300–500 to replace).

The models it hits hardest

Ranked by how often the fault came up as a share of that model's own tests, not by raw count — a fault in 8% of a small model's tests says more about that model than one in 3% of the Fiesta's. A linked row has a page of its own.
