Is the Grand C-Max getting worse?

The fail rate rose 4.8 points to 27.6% from 2022 to 2025 while the median one tested aged 2 years, which is about what ageing alone predicts (5.3 points). Read it as the fleet getting older rather than the model changing.

Fail rate is first attempts at class 4 tests. Median age is the age of a typical Grand C-Max at its test that year, and it is the number to watch: across the whole fleet each extra year of age adds roughly 1.9 points to the fail rate, so a model whose age and fail rate rise together is simply getting older.

The exact defects that fail it

Every failure item DVSA recorded against a Grand C-Max in 2025, counted by how many tests each one appeared on.

  1. 1Brake pads: less than 1.5 mm thick1,362 tests
  2. 2Joints: constant velocity boot split or insecure, no longer prevents the ingress of dirt1,114 tests
  3. 3Condition: has ply or cords exposed1,034 tests
  4. 4Tread depth: tread depth below requirements of 1.6mm1,028 tests
  5. 5Stop lamp: not working851 tests
  6. 6Tyre pressure monitoring system: malfunctioning or obviously inoperative731 tests
  7. 7Pins and bushes: pin or bush excessively worn726 tests
  8. 8Position lamp: not working677 tests

What wears out first

Advisories are the tester flagging wear that is still legal. A typical Grand C-Max collects 2.81 of them per test, and these are the ones that come up most. Treat it as the running-repairs list for the next year or two.
