2020 Lexus Ux — MOT failures & pass rate
Across 12,261 MOT tests, the 2020 Lexus Ux recorded a 96.2% pass rate. Small SUVs of a similar age fail 7.9% of the time, so this is 4.1pp better than the group it competes with. Failures cluster in tyres, visibility and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (3.0%) and visibility (1.8%) 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 223 times.
Mileage is the strongest signal on the record: 2.4% of 0-30k cars fail, rising to 8.7% once past 90-120k — 3.6× the risk.
Tyres is the most common advisory, noted on 17.8% of tests — work that passed today but is likely due soon.
The trend is worsening — 1.8% of tests failed in 2022 against 4.6% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.

| 6 | Lighting & signalling | 0.1% | 19 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 7,195 | 2.4% |
| 30-60k | 4,290 | 5.5% |
| 60-90k | 632 | 6.7% |
| 90-120k | 126 | 8.7% |
Failure rate by age
Trend over time

What to check before buying a 2020 Ux
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.
- Visibility (1.8% 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 (1.3% 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.
