2014 Lexus Nx — MOT failures & pass rate
Across 4,431 MOT tests, the 2014 Lexus Nx recorded a 91.9% pass rate. Mid-size SUVs of a similar age fail 18.0% of the time, so this is 9.9pp better than the group it competes with. Failures cluster in tyres, visibility and brakes.
What the MOT record shows
No single area dominates — tyres (3.7%) and visibility (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 headlamp aim — wipers alone was recorded 148 times.
Mileage is the strongest signal on the record: 4.0% of 0-30k cars fail, rising to 8.1% once past 150k — 2.0× the risk.
Tyres is the most common advisory, noted on 21.9% of tests — work that passed today but is likely due soon.
The trend is worsening — 6.5% of tests failed in 2021 against 10.0% 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 | 21.9% | 972 |
| 2 | Brakes | 14.3% | 635 |

| 4 | Other defects | 5.7% | 253 |
| 5 | Visibility | 3.4% | 149 |
| 6 | Body, structure & corrosion | 0.2% | 10 |
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 | 225 | 4.0% |
| 30-60k | 1,630 | 7.3% |
| 60-90k | 1,690 | 8.0% |
| 90-120k | 690 | 12.2% |
| 120-150k | 159 | 5.7% |
| 150k+ | 37 | 8.1% |
Failure rate by age

What to check before buying a 2014 Nx
The failure pattern for this year is specific enough to inspect against: tyres accounted for 3.7% of tests. Start there.
- Tyres (3.7% 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 (2.9% 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 (2.0% 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.
