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 334 of 360 failed first attempts (92.8%) that recorded an odometer reading in 2025 — the subset the age-and-mileage comparison can be computed on. 7.2% of failures are excluded for want of a mileage reading, so treat these shares as indicative for this model year.
Standout: Service brake imbalance (rear) — 10.2% of this year's failed first attempts
Recorded on 34 of those tests. It tops the table on elevation — about 8.1× more often than on similar cars of the same age and mileage. 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.
