2020 Lexus Rx — MOT failures & pass rate
5,332 MOT tests on the 2020 Lexus Rx are in this dataset, and 96.8% of them passed. Large SUVs of a similar age fail 9.3% of the time, so this is 6.0pp 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 (2.5%) and visibility (1.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, wipers and headlamp aim — tread depth alone was recorded 79 times.
Mileage matters less than usual here: the 2020 Rx fails 2.3% of the time in the 0-30k band and 4.8% at 60-90k, a spread of only 2.5 points.
Advisories point at the next bill rather than this one: tyres was flagged on 19.0% of tests without failing them.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Tyres | 19.0% | 1,013 |
| 2 | Other defects | 3.3% | 177 |

| 5 | Visibility | 1.8% | 94 |
| 6 | Lighting & signalling | 0.1% | 4 |
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 | 2,871 | 2.3% |
| 30-60k | 2,204 | 4.2% |
| 60-90k | 229 | 4.8% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 2020 Rx
On a 2020 Rx, tyres is what the MOT record says goes wrong most — it appeared in 2.5% of tests. Check these areas before you commit.
- Tyres (2.5% 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 (1.0% 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 (0.7% 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.
