2006 Lexus Gs450H — MOT failures & pass rate
The 2006 Lexus Gs450H passed 81.6% of its 1,623 recorded MOT tests. Against all cars of a similar age (27.3% fail rate), the 2006 Gs450H comes out 9.0pp better. Failures cluster in lighting & signalling, brakes and tyres.
What the MOT record shows
No single area dominates — lighting & signalling (9.8%) and brakes (7.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are position lamp, headlamp aim and shock absorbers — position lamp alone was recorded 90 times.
A 150k+ example is materially riskier than a 30-60k one: 20.3% versus 10.0%.
Brakes is the most common advisory, noted on 23.3% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 18.4% in 2021 to 16.0% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2006 Gs450H
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 9.8% of tests. Start there.
- Lighting & signalling (9.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (7.3% 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.
- Tyres (5.9% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
