Is the M3 getting worse?

The fail rate fell 1.4 points to 11.6% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 1.4 points, so it is holding up better than the fleet average for its age.

Fail rate is first attempts at class 4 tests. Median age is the age of a typical M3 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 M3 in 2025, counted by how many tests each one appeared on.

  1. 1Condition: has ply or cords exposed191 tests
  2. 2Coil spring: fractured or broken151 tests
  3. 3Condition: has a cut in excess of the requirements deep enough to reach the ply or cords133 tests
  4. 4Catalyst emissions: Lambda reading after 2nd fast idle outside specified limits113 tests
  5. 5Malfunction indicator lamp: inoperative or indicates a malfunction107 tests
  6. 6Tread depth: tread depth below requirements of 1.6mm103 tests
  7. 7Anti-lock braking system: warning lamp indicates an ABS fault69 tests
  8. 8SRS malfunction indicator lamp: warning lamp indicates a fault69 tests

What wears out first

Advisories are the tester flagging wear that is still legal. A typical M3 collects 2.51 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.

By section, tyres appears in 29.6% of failures, suspension appears in 26.2% of failures, lamps, reflectors and electrical equipment appears in 25.4% of failures.

Does age change the odds?

Sharply. At 3 to 5 years old the fail rate was 5.6%; at 14+ years it was 12.6%. The median BMW M3 tested in 2025 was 17 years old with 73,606 miles.

Is the BMW M3 getting less reliable?

The fail rate fell 1.4 points to 11.6% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 1.4 points, so it is holding up better than the fleet average for its age.
