MG Rv8 MOT Failures
An analysis of 780 real DVSA MOT tests on the MG Rv8 — what fails, how often, and how that compares to every other car on UK roads.
Where the MG Rv8 fails its MOT
The single biggest MOT failure point on the MG Rv8 is fluid leak — this model is 58 times more likely to fail on this item than the average car on UK roads. That makes it a major concern for anyone buying or owning this model. Across 780 MOT tests, 14.42% of all MG Rv8 tests recorded this as a failure.
Exhaust and emissions failures often point to catalytic converter degradation, lambda sensor faults, or — in diesel models — DPF problems. These can be expensive to fix and will cause an immediate MOT failure.
Other notable weak points include brake hoses perished or damaged (36x the fleet average) and coil springs broken (7.2x the fleet average). These ratios compare the MG Rv8'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 3 categories: Exhaust & Emissions, Brakes, Suspension. If you're inspecting a MG Rv8 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.
What to check before buying a MG Rv8
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a MG Rv8:
Exhaust & Emissions — check for fluid leak. Brakes — check for brake hoses perished or damaged. Suspension — check for coil springs broken.
