Is the 300 getting worse?
The fail rate fell 0.4 points to 30.3% from 2022 to 2025 while the median one tested aged 3 years, which is about what ageing alone predicts (1.4 points). Read it as the fleet getting older rather than the model changing.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 4,243 | 15 | 30.7% | 22.5% | |
| 2023 | 3,837 | 16 | 31.2% | 22.8% | |
| 2024 | 3,051 | 17 | 29.9% | 23.2% | |
| 2025 | 2,768 | 18 | 30.3% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical 300 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 300 in 2025, counted by how many tests each one appeared on.
- 1Rbt (sp): efficiency below requirements176 tests
- 2Rbt (sp): efficiency less than 50% of the required value170 tests
- 3Track rod end: ball joint has excessive play157 tests
- 4Pins and bushes: pin or bush excessively worn152 tests
- 5Ball joint: ball joint excessively worn124 tests
- 6Position lamp: not working113 tests
- 7Anti-lock braking system: warning lamp indicates an ABS fault106 tests
- 8Parking brake performance: inoperative on one side104 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical 300 collects 3.36 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.
- 1Engine oil leaks: leaking excessively from engine422 tests
- 2Tread depth: tread depth below requirements of 1.6mm421 tests
- 3Brake discs: in such a condition that it is seriously weakened416 tests
- 4Pins and bushes: pin or bush excessively worn401 tests
- 5Rigid brake pipes: excessively corroded376 tests
- 6Sub-frame: corroded and seriously weakened232 tests
- 7Brake pads: less than 1.5 mm thick211 tests

What does a Chrysler-Jeep 300 usually fail on?
The single most common failure is "Rbt (sp): efficiency below requirements", recorded on 176 failed tests, followed by "Rbt (sp): efficiency less than 50% of the required value" and "Track rod end: ball joint has excessive play". By section, brakes appears in 63.2% of failures, suspension appears in 44.9% of failures, lamps, reflectors and electrical equipment appears in 34.4% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was n/a%; at 14+ years it was 30.3%. The median Chrysler-Jeep 300 tested in 2025 was 18 years old with 110,623 miles.
Is the Chrysler-Jeep 300 getting less reliable?
The fail rate fell 0.4 points to 30.3% from 2022 to 2025 while the median one tested aged 3 years, which is about what ageing alone predicts (1.4 points). Read it as the fleet getting older rather than the model changing.
