An analysis of 359 real DVSA MOT tests on the MG C — what fails, how often, and how that compares to every other car on UK roads.
Where the MG C fails its MOT
The single biggest MOT failure point on the MG C is suspension pin, bush or joint worn — this model is 201 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 359 MOT tests, 9.71% of all MG C tests recorded this as a failure.
Suspension failures typically mean worn bushes, drop links, or dampers. These affect handling and tyre wear. Budget £150–£400 per corner at an independent garage for full suspension overhaul.
Other notable weak points include wheel bearings worn (40x the fleet average) and fluid leak (12x the fleet average). These ratios compare the MG C'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 2 categories: Suspension, Exhaust & Emissions. If you're inspecting a MG C 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.
