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 4,901 of 4,904 failed first attempts (99.9%) that recorded an odometer reading in 2025 — the subset the age-and-mileage comparison can be computed on.
Standout: Anti-roll bars — Linkage (front) — 7.0% of this year's failed first attempts
Recorded on 345 of those tests. It tops the table on elevation — about 52× more often than on similar cars of the same age and mileage. That is what makes it unusual for its class, which is a different question from what is most likely to fail; the buying checklist ranks by that. The full ranked list is in the table below.
