2010 Lexus Rx 450H -I — MOT failures & pass rate
273 MOT tests on the 2010 Lexus Rx 450H -I are in this dataset, and 85.0% of them passed. That is 9.5 percentage points better than all cars of a similar age, which fail at 24.5%. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (12.4%) and suspension (9.9%) 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 36 times.
A 150k+ example is materially riskier than a 60-90k one: 18.6% versus 10.8%.
Suspension is the most common advisory, noted on 35.5% of tests — work that passed today but is likely due soon.
The trend is worsening — 8.2% of tests failed in 2021 against 17.5% in 2025, the usual pattern as a fleet ages.

| 90-120k | 94 | 17.0% |
| 120-150k | 61 | 16.4% |
| 150k+ | 43 | 18.6% |
Failure rate by age

What to check before buying a 2010 Rx 450H -I
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 12.4% of tests. Start there.
- Lighting & signalling (12.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (9.9% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Brakes (3.7% 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.
