In 2025, 34,568 Ford Grand C-Max cars had a regular MOT in Great Britain. 65% passed first time, compared with 71% for all cars of the same ages, which makes the Grand C-Max worse than average. Adjusted for age, it ranks 190 of the 217 most-tested car models.
That comparison matters: older cars fail more often, so a raw pass rate flatters models that are mostly young. We compare each model against every car on the road at the same age.
Pass rate by age
At 6 years old, 76% of Grand C-Maxs passed first time (all cars that age: 84%). By 14 years, that figure is 58% (all cars: 61%). It trails the average car at most ages, most noticeably at 7 years (9 points behind).

What to check when buying a used Grand C-Max
Based on where the Grand C-Max fails more often than other cars, these are the checks worth making before you buy:
- Seat belts and airbags: Pull every belt out fully and let it retract, check the buckles latch, and make sure the airbag light goes out after starting. More
- Tyres: Check tread across the whole width (uneven wear hints at alignment or suspension faults), and look for cuts, bulges and mismatched brands. Repair guide
- Body and structure: Get underneath with a torch: sills, jacking points, subframe mounts and floor pans. Structural rust is the failure that can make a car uneconomic to fix. Repair guide
Then check the individual car: its own MOT history will show whether it follows the pattern. A car with repeated advisories in the same weak area is more likely to fail its next test.
