What goes wrong?
The most common MOT failure reasons are a suspension pin, bush or joint excessively worn, brake pipe damaged or excessively corroded and a brake lining or pad worn below 1.5mm. The top issue, a suspension pin, bush or joint excessively worn, caused 1,356 failures in 2024. Checking tread depth (1.6mm legal minimum, 3mm recommended) before your test can save an unnecessary fail. You can check prices at Black Circles if you need replacements.

How serious are these failures?
Not all MOT failures are equal. 60.4% of Asx failures are safety items (worn brakes, tyre damage, steering play). The car still drives, but you shouldn't. Only 0% are the kind that would actually strand you. When it does fail, the average repair bill is around £120.
The warranty question
A new Asx passes its MOT 91.7% of the time. By 7 years old that drops to 82.5%, a 9.2 percentage point fall, right as the manufacturer warranty runs out. At 10 years it's down to 76.8%. With an average repair bill of £120 when things go wrong, an extended warranty can make sense on a Asx that's past its third birthday.
