Is the Xk getting worse?
The fail rate rose 1.1 points to 17.5% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 4.2 points, so it is holding up better than the fleet average for its age.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 8,387 | 13 | 16.4% | 22.5% | |
| 2023 | 8,406 | 14 | 16% | 22.8% | |
| 2024 | 7,120 | 15 | 18% | 23.2% | |
| 2025 | 7,533 | 16 | 17.5% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Xk 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 Xk in 2025, counted by how many tests each one appeared on.
- 1Ball joint dust cover: ball joint dust cover no longer prevents the ingress of dirt375 tests
- 2Linkage ball joint dust cover: ball joint dust cover no longer prevents the ingress of dirt168 tests
- 3Track rod end: ball joint dust cover excessively damaged or deteriorated so that it no longer prevents the ingress of dirt128 tests
- 4Pins and bushes: pin or bush excessively worn85 tests
- 5Condition: has a cut in excess of the requirements deep enough to reach the ply or cords77 tests
- 6Washers: not working69 tests
- 7Malfunction indicator lamp: inoperative or indicates a malfunction67 tests
- 8Condition: has ply or cords exposed67 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Xk collects 2.57 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 1.6mm798 tests
- 2Condition: has a tear, caused by separation or partial failure of its structure546 tests
- 3Sub-frame: corroded and seriously weakened523 tests
- 4Pins and bushes: pin or bush excessively worn486 tests
- 5Brake discs: in such a condition that it is seriously weakened387 tests
- 6Brake pads: less than 1.5 mm thick346 tests

By section, suspension appears in 46.3% of failures, lamps, reflectors and electrical equipment appears in 22.1% of failures, tyres appears in 21.3% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was 0%; at 14+ years it was 20.7%. The median Jaguar Xk tested in 2025 was 16 years old with 61,888 miles.
Is the Jaguar Xk getting less reliable?
The fail rate rose 1.1 points to 17.5% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 4.2 points, so it is holding up better than the fleet average for its age.
