Lexus Rx 450H F MOT pass rate & common failures
Across 2 model years and 3,457 tests, the Lexus Rx 450H F passes its MOT 90.2% of the time. All cars of a similar age fail 20.5% of the time, so this is 10.7pp better than the group it competes with. Its most common failure areas are lighting & signalling, tyres and suspension.
What the MOT record shows
No single area dominates — lighting & signalling (3.4%) and tyres (3.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, position lamp and tread depth — wipers alone was recorded 102 times.
Mileage matters less than usual here: the Rx 450H F fails 10.8% of the time in the 0-30k band and 14.7% at 150k+, a spread of only 3.9 points.
Tyres is the most common advisory, noted on 23.6% of tests — work that passed today but is likely due soon.

What to check before buying a Lexus Rx 450H F
- Lighting & signalling (3.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (3.4% 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.
- Suspension (3.3% 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.
