These MOT failure patterns show up more often on this registration year than on similar cars of the same class, age, and mileage.
Shares below are measured across the 1,461 of 1,513 failed first attempts (96.6%) that recorded an odometer reading in 2025 — the subset the age-and-mileage comparison can be computed on. 3.4% of failures are excluded for want of a mileage reading, so treat these shares as indicative for this model year.
Standout: Suspension arm (rear) — 16.4% of this year's failed first attempts
Recorded on 240 of those tests. It tops the table on elevation — about 21× more often than on similar cars of the same age and mileage. On this year it is also the commonest failure, so it answers both questions at once. The full ranked list is in the table below.
