What goes wrong?
The most common MOT failure reasons are a suspension pin, bush or joint excessively worn, tyre tread depth not in accordance with the requirements and brake pipe damaged or excessively corroded. The top issue, a suspension pin, bush or joint excessively worn, caused 2,301 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. 52.9% of Sx4 failures are safety items (worn brakes, tyre damage, steering play). The car still drives, but you shouldn't. Only 12.1% are the kind that would actually strand you. When it does fail, the average repair bill is around £136.
The warranty question
A new Sx4 passes its MOT 92.6% of the time. By 7 years old that drops to 84.2%, a 8.4 percentage point fall, right as the manufacturer warranty runs out. At 10 years it's down to 72.5%. With an average repair bill of £136 when things go wrong, an extended warranty can make sense on a Sx4 that's past its third birthday.
