2007 Lexus Rx 400H Sr — MOT failures & pass rate
250 MOT tests on the 2007 Lexus Rx 400H Sr are in this dataset, and 81.2% of them passed. All cars of a similar age fail 26.9% of the time, so this is 8.1pp better than the group it competes with. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
No single area dominates — lighting & signalling (10.4%) and brakes (9.2%) 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 service brake performance — position lamp alone was recorded 16 times.
Condition tracks the odometer closely. Failures run at 10.6% in the 90-120k band and 24.1% in the 150k+ band, a 13.4-point spread — more than double.
Advisories point at the next bill rather than this one: suspension was flagged on 47.2% of tests without failing them.
The trend is worsening — 15.8% of tests failed in 2021 against 23.1% in 2025, the usual pattern as a fleet ages.

| 120-150k | 71 | 21.1% |
| 150k+ | 108 | 24.1% |
Failure rate by age

What to check before buying a 2007 Rx 400H Sr
On a 2007 Rx 400H Sr, lighting & signalling is what the MOT record says goes wrong most — it appeared in 10.4% of tests. Check these areas before you commit.
- Lighting & signalling (10.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (9.2% 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.
- Suspension (8.0% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
