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 750 failed first attempts in 2025 that the age-and-mileage comparison can be computed on.
Standout: Macpherson strut (front) — 5.7% of this year's failed first attempts
Recorded on 43 of those tests. It tops the table on elevation — about 9.1× 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.
No patterns met the strongest callout thresholds on this page; showing the highest-lift rows that still cleared the display floors.
