Fiat 126 MOT Failures
An analysis of 820 real DVSA MOT tests on the Fiat 126 — what fails, how often, and how that compares to every other car on UK roads.
Where the Fiat 126 fails its MOT
The single biggest MOT failure point on the Fiat 126 is structural corrosion — this model is 154 times more likely to fail on this item than the average car on UK roads. That makes it an extreme outlier for anyone buying or owning this model. Across 820 MOT tests, 11.54% of all Fiat 126 tests recorded this as a failure.
Bodywork failures usually mean structural corrosion — not cosmetic rust, but rot that affects the car's structural integrity. Check sills, subframes, and chassis rails carefully, especially on older examples.
Other notable weak points include wheel bearings worn (88x the fleet average), headlight fault (37x the fleet average), brake hoses perished or damaged (27x the fleet average), and windscreen washers not working or not providing... (26x the fleet average). These ratios compare the Fiat 126's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 6 categories: Bodywork, Suspension, Lights & Electrics, Brakes, Wipers & Windscreen and others. If you're inspecting a Fiat 126 before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
