Lexus Ux 300E + MOT pass rate & common failures
Across 6 model years and 2,595 tests, the Lexus Ux 300E + passes its MOT 96.0% of the time. That is 4.5 percentage points better than all cars of a similar age, which fail at 8.5%. Its most common failure areas are tyres, lighting & signalling and visibility.
What the MOT record shows
No single area dominates — tyres (3.2%) 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 52 times.
A 60-90k example is materially riskier than a 0-30k one: 7.9% versus 3.0%.
Advisories point at the next bill rather than this one: tyres was flagged on 16.5% of tests without failing them.

What to check before buying a Lexus Ux 300E +
- Tyres (3.2% 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 (1.1% 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.
