Lexus Ux MOT pass rate & common failures
The Lexus Ux appears in 38,324 MOT tests spanning model years 2018–2024, and 96.5% of them passed. That is 4.4 percentage points better than small SUVs of a similar age, which fail at 8.0%. Its most common failure areas are tyres, visibility and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (2.9%) and visibility (1.5%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, headlamp aim and tread depth — wipers alone was recorded 595 times.
Mileage is the strongest signal on the record: 2.3% of 0-30k cars fail, rising to 7.7% once past 120-150k — 3.3× the risk.
Tyres is the most common advisory, noted on 16.9% of tests — work that passed today but is likely due soon.

What to check before buying a Lexus Ux
- Tyres (2.9% 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.
- Visibility (1.5% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Lighting & signalling (1.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
