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 3,732 failed first attempts in 2025 that the age-and-mileage comparison can be computed on.
Standout: Suspension arm (rear) — 5.3% of this year's failed first attempts
