Is the Gs getting worse?
The fail rate rose 1 point to 8.9% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 8 points, so it is holding up better than the fleet average for its age.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 3,535 | 8 | 7.9% | 22.5% | |
| 2023 | 3,515 | 9 | 8.2% | 22.8% | |
| 2024 | 3,012 | 10 | 9.5% | 23.2% | |
| 2025 | 3,186 | 11 | 8.9% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Gs 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 Gs in 2025, counted by how many tests each one appeared on.
- 1Condition: has ply or cords exposed43 tests
- 2Tread depth: tread depth below requirements of 1.6mm40 tests
- 3Condition: has a cut in excess of the requirements deep enough to reach the ply or cords37 tests
- 4Tyre pressure monitoring system: malfunctioning or obviously inoperative33 tests
- 5Brake pads: less than 1.5 mm thick29 tests
- 6Shock absorbers: has a serious fluid leak24 tests
- 7Wipers: does not clear the windscreen effectively20 tests
- 8Position lamp: not working13 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Gs 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 1.6mm460 tests
- 2Brake discs: in such a condition that it is seriously weakened190 tests
- 3Condition: has a tear, caused by separation or partial failure of its structure177 tests
- 4Brake pads: less than 1.5 mm thick174 tests
- 5Shock absorbers: has a serious fluid leak107 tests
- 6Rigid brake pipes: excessively corroded105 tests

Questions
What is the Lexus Gs MOT pass rate?
90.9% of the 3,254 Lexus Gs first-attempt MOTs in 2025 passed. The fail rate of 9.1% compares with 22.6% across all cars. A further 2.5% passed after a defect was fixed during the test visit.
What does a Lexus Gs usually fail on?
The single most common failure is "Condition: has ply or cords exposed", recorded on 43 failed tests, followed by "Tread depth: tread depth below requirements of 1.6mm" and "Condition: has a cut in excess of the requirements deep enough to reach the ply or cords". By section, tyres appears in 51.5% of failures, brakes appears in 29% of failures, lamps, reflectors and electrical equipment appears in 17.8% 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 17.5%. The median Lexus Gs tested in 2025 was 11 years old with 78,344 miles.
Is the Lexus Gs getting less reliable?
The fail rate rose 1 point to 8.9% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 8 points, so it is holding up better than the fleet average for its age.
