2006 Lexus Gs — MOT failures & pass rate
343 MOT tests on the 2006 Lexus Gs are in this dataset, and 83.4% of them passed. Executive cars of a similar age fail 23.7% of the time, so this is 7.0pp better than the group it competes with. Failures cluster in lighting & signalling, tyres and brakes.
What the MOT record shows
Lighting & signalling dominates the failure mix at 12.5% of all tests — 6.7 points clear of tyres, so it is the first thing to check.
At component level the recurring items are position lamp, shock absorbers and tread depth — position lamp alone was recorded 25 times.
Mileage is the strongest signal on the record: 13.3% of 60-90k cars fail, rising to 23.7% once past 150k.
Advisories point at the next bill rather than this one: suspension was flagged on 27.1% of tests without failing them.
The trend is worsening — 15.0% of tests failed in 2021 against 17.4% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |

| 1 | Suspension | 27.1% | 93 |
| 2 | Tyres | 24.5% | 84 |
| 3 | Brakes | 20.7% | 71 |

| 5 | Lighting & signalling | 6.4% | 22 |
| 6 | Emissions & environmental | 6.1% | 21 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.

| 60-90k | 75 | 13.3% |
| 90-120k | 85 | 17.6% |
| 120-150k | 89 | 13.5% |
| 150k+ | 76 | 23.7% |

What to check before buying a 2006 Gs
On a 2006 Gs, lighting & signalling is what the MOT record says goes wrong most — it appeared in 12.5% of tests. Check these areas before you commit.
- Lighting & signalling (12.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (5.8% 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 (5.5% 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.
