2010 Lexus Gs450H — MOT failures & pass rate
396 MOT tests on the 2010 Lexus Gs450H are in this dataset, and 84.3% of them passed. That is 8.7 percentage points better than all cars of a similar age, which fail at 24.3%. Failures cluster in lighting & signalling, tyres and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (7.1%) and tyres (5.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, position lamp and tread depth — headlamp aim alone was recorded 15 times.
A 150k+ example is materially riskier than a 30-60k one: 6.5% versus 18.1%.
Advisories point at the next bill rather than this one: brakes was flagged on 26.0% of tests without failing them.
The trend is improving — the fail rate fell from 19.8% in 2021 to 14.3% in 2025, as the worst-kept examples leave the fleet.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Brakes | 26.0% | 103 |
| 2 | Tyres | 19.4% | 77 |
| 3 | Suspension | 16.2% | 64 |
| 4 | Other defects | 6.6% | 26 |
| 5 | Body, structure & corrosion | 5.6% | 22 |
| 6 | Lighting & signalling | 4.0% | 16 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 30-60k | 72 | 18.1% |
| 60-90k | 128 | 18.0% |
| 90-120k | 79 | 12.7% |
| 120-150k | 71 | 15.5% |
| 150k+ | 31 | 6.5% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2021 | 86 | 19.8% |
| 2022 | 82 | 15.8% |

What to check before buying a 2010 Gs450H
On a 2010 Gs450H, lighting & signalling is what the MOT record says goes wrong most — it appeared in 7.1% of tests. Check these areas before you commit.
- Lighting & signalling (7.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (5.3% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Brakes (5.1% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
