2020 Lexus Rc — MOT failures & pass rate
Across 811 MOT tests, the 2020 Lexus Rc recorded a 93.6% pass rate. Against all cars of a similar age (9.3% fail rate), the 2020 Rc comes out 2.9pp better. Failures cluster in tyres, visibility and brakes.
What the MOT record shows
One area stands out: tyres, recorded in 5.9% of tests against 1.4% for the next-worst category.
At component level the recurring items are wipers, tread depth and registration plates — wipers alone was recorded 12 times.
Tyres is the most common advisory, noted on 22.3% of tests — work that passed today but is likely due soon.

| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 502 | 5.4% |
| 30-60k | 276 | 8.0% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

| 2024 | 268 | 5.2% |
| 2025 | 263 | 6.5% |
What to check before buying a 2020 Rc
The failure pattern for this year is specific enough to inspect against: tyres accounted for 5.9% of tests. Start there.
- Tyres (5.9% 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 (1.4% 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.
- Brakes (0.7% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
