Is the Id4 getting worse?
The fail rate rose 7.3 points to 9.9% from 2022 to 2025, against a rising rate across all cars.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 666 | 1 | 2.6% | 22.5% | |
| 2023 | 1,532 | 2 | 2.9% | 22.8% | |
| 2024 | 4,529 | — | 8.9% | 23.2% | |
| 2025 | 8,639 | — | 9.9% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Id4 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 Id4 in 2025, counted by how many tests each one appeared on.
- 1Condition: has a cut in excess of the requirements deep enough to reach the ply or cords303 tests
- 2Condition: has ply or cords exposed280 tests
- 3Tread depth: tread depth below requirements of 1.6mm200 tests
- 4Shock absorbers: has a serious fluid leak82 tests
- 5Wipers: does not clear the windscreen effectively45 tests
- 6Washers: not working25 tests
- 7Position lamp: not working24 tests
- 8SRS malfunction indicator lamp: warning lamp indicates a fault22 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Id4 collects 1.93 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.
- 1Tread depth: tread depth below requirements of 1.6mm1,852 tests
- 2Condition: has a tear, caused by separation or partial failure of its structure354 tests
- 3Tread depth: tread pattern not visible over the whole tread area when minimum depth required is 1.0mm330 tests
- 4Non-component advisories: Child Seat fitted not allowing full inspection of adult belt318 tests

- 6Non-component advisories: Nail in tyre218 tests

By section, tyres appears in 73.3% of failures, suspension appears in 11.7% of failures, visibility appears in 9.2% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was 10.1%; at 3-5 years it was 10.1%. The median Volkswagen Id4 tested in 2025 was 3 years old with 37,508 miles.
Is the Volkswagen Id4 getting less reliable?
The fail rate rose 7.3 points to 9.9% from 2022 to 2025, against a rising rate across all cars.
