Is the Nx getting worse?
The fail rate rose 2.4 points to 7.3% from 2022 to 2025 while the median one tested aged 2 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 | 20,765 | 5 | 4.9% | 22.5% | |
| 2023 | 24,776 | 5 | 5.6% | 22.8% | |
| 2024 | 24,133 | 6 | 6.7% | 23.2% | |
| 2025 | 26,218 | 7 | 7.3% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Nx 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 Nx in 2025, counted by how many tests each one appeared on.
- 1Wipers: does not clear the windscreen effectively354 tests
- 2Condition: has a cut in excess of the requirements deep enough to reach the ply or cords339 tests
- 3Brake pads: less than 1.5 mm thick261 tests
- 4Pins and bushes: pin or bush excessively worn234 tests
- 5Tread depth: tread depth below requirements of 1.6mm202 tests
- 6Condition: has ply or cords exposed194 tests
- 7Tyre pressure monitoring system: malfunctioning or obviously inoperative110 tests
- 8Linkage ball joint dust cover: ball joint dust cover no longer prevents the ingress of dirt83 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Nx collects 2.26 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 1.6mm3,698 tests
- 2Condition: has a tear, caused by separation or partial failure of its structure2,480 tests
- 3Pins and bushes: pin or bush excessively worn2,174 tests
- 4Brake pads: less than 1.5 mm thick1,635 tests
- 5Brake discs: in such a condition that it is seriously weakened1,467 tests
- 6Brake discs: significantly and obviously worn817 tests
- 7Tread depth: tread pattern not visible over the whole tread area when minimum depth required is 1.0mm636 tests
- 8Non-component advisories: Child Seat fitted not allowing full inspection of adult belt538 tests

By section, tyres appears in 43.7% of failures, suspension appears in 21.3% of failures, visibility appears in 20.6% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was 4.4%; at 10-13 years it was 10.7%. The median Lexus Nx tested in 2025 was 6 years old with 44,660 miles.
Is the Lexus Nx getting less reliable?
