2007 Lexus Rx400H — MOT failures & pass rate
13,098 MOT tests on the 2007 Lexus Rx400H are in this dataset, and 81.6% of them passed. All cars of a similar age fail 26.9% of the time, so this is 8.5pp better than the group it competes with. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 11.8% of tests against 7.6% for the next-worst category.
At component level the recurring items are position lamp, headlamp aim and tread depth — position lamp alone was recorded 894 times.
A 150k+ example is materially riskier than a 0-30k one: 22.0% versus 15.4%.
The petrol cars hold up better: 16.4% fail against 18.6% for hybrid, a 2.2-point gap across 11,889 tests.
Suspension is the most common advisory, noted on 39.1% of tests — work that passed today but is likely due soon.
The trend is worsening — 17.2% of tests failed in 2021 against 19.6% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2007 Rx400H
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 11.8% of tests. Start there.
- Lighting & signalling (11.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (7.6% 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 (6.5% 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.
