2014 Lexus Rx — MOT failures & pass rate
8,792 MOT tests on the 2014 Lexus Rx are in this dataset, and 91.0% of them passed. That is 6.1 percentage points better than large SUVs of a similar age, which fail at 15.1%. Failures cluster in tyres, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — tyres (4.5%) and lighting & signalling (2.9%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, brake pads and tread depth — wipers alone was recorded 176 times.
Condition tracks the odometer closely. Failures run at 3.1% in the 0-30k band and 18.5% in the 150k+ band, a 15.4-point spread — more than double.
Tyres is the most common advisory, noted on 22.6% of tests — work that passed today but is likely due soon.
The trend is worsening — 8.4% of tests failed in 2021 against 10.9% 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.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Tyres | 22.6% | 1,990 |
| 2 | Suspension | 16.0% | 1,409 |

| 5 | Visibility | 3.6% | 318 |
| 6 | Lighting & signalling | 2.2% | 194 |
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 | 291 | 3.1% |
| 30-60k | 2,694 | 6.7% |
| 60-90k | 3,501 | 9.2% |
| 90-120k | 1,647 | 10.7% |
| 120-150k | 497 | 14.9% |
| 150k+ | 162 | 18.5% |
Failure rate by age
Trend over time

What to check before buying a 2014 Rx
The failure pattern for this year is specific enough to inspect against: tyres accounted for 4.5% of tests. Start there.
- Tyres (4.5% 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.
- Lighting & signalling (2.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (2.3% 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.
