What the MOT tests show
What we know
0.2 fails per 100 MOT tests at 3 years, against 0.6 for all class 4 vehicles tested at 3 (all test years). That is about average.
Why it matters
A suspension fail stops the car passing until it is fixed; the most common one is rated major by DVSA.
What to check
Push down hard on each corner: it should rise once and settle. Listen for knocks over speed bumps and look behind each wheel for snapped springs or split rubber bushes.
