Visibility: does not clear the windscreen effectively
This one item accounted for 0.8% of every MOT test carried out in Great Britain, and it is among the commonest faults on 485 different model-and-year combinations. Here is where it clusters, and what it looks like on a car you are standing in front of.
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.
