2021 Lexus Ux 300E + — MOT failures & pass rate
2,105 MOT tests on the 2021 Lexus Ux 300E + are in this dataset, and 96.1% of them passed. That is 4.8 percentage points better than all cars of a similar age, which fail at 8.7%. Failures cluster in tyres, lighting & signalling and visibility.
What the MOT record shows
No single area dominates — tyres (3.0%) and lighting & signalling (1.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, tread depth and wipers — headlamp aim alone was recorded 40 times.
Mileage matters less than usual here: the 2021 Ux 300E + fails 2.9% of the time in the 0-30k band and 6.1% at 60-90k, a spread of only 3.1 points.
Tyres is the most common advisory, noted on 16.1% of tests — work that passed today but is likely due soon.

What to check before buying a 2021 Ux 300E +
The failure pattern for this year is specific enough to inspect against: tyres accounted for 3.0% of tests. Start there.
- Tyres (3.0% 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.
- Lighting & signalling (1.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (1.2% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
