2023 BMW X3 — MOT failures & pass rate
The 2023 BMW X3 passed 98.0% of its 302 recorded MOT tests. Mid-size SUVs of a similar age fail 5.6% of the time, so this is 3.6pp better than the group it competes with. Failures cluster in tyres, lighting & signalling and visibility.
What the MOT record shows
No single area dominates — tyres (1.7%) and lighting & signalling (1.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, wipers and side repeaters — headlamp aim alone was recorded 6 times.

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 | 4.6% | 14 |
| 2 | Other defects | 1.7% | 5 |
| 3 | Visibility | 1.3% | 4 |
| 4 | Suspension | 0.7% | 2 |
| 5 | Lighting & signalling | 0.3% | 1 |
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 | 236 | 2.5% |
| 30-60k | 63 | 0.0% |
By fuel type
| Fuel | Tests | Fail rate |
|---|---|---|
| Diesel | 146 | 2.7% |
| Hybrid | 137 | 1.5% |
What to check before buying a 2023 X3
The failure pattern for this year is specific enough to inspect against: tyres accounted for 1.7% of tests. Start there.
- Tyres (1.7% 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.
- Lighting & signalling (1.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (0.7% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
