Used buying checklist
BMW X6 reliability, common problems and used buying checks
A used BMW X6 looks better than average for reliability in UK MOT data: 13.0% of 15,862 tests failed, compared with 18.7% across all indexed models. A good example should have a clean MOT history for suspension and steering, windscreen, wipers, and mirrors, and emissions, engine, and exhaust.
It can be, if the exact car has a clean history for suspension and steering, windscreen, wipers, and mirrors, and emissions, engine, and exhaust.
Start with suspension and steering, windscreen, wipers, and mirrors, and emissions, engine, and exhaust, then compare the car's mileage and recall record below.
Sources used: DVSA MOT tests (Apr 2026); vehicle recalls (Apr 2026); MOT fault wording (May 2025). MOT data does not capture every reliability issue, especially intermittent engine, gearbox or infotainment faults that do not appear during the test.

Should you buy a used BMW X6?
87.1% of the MOT tests we analysed for this model passed. The model's recorded failure rate is 13.0%, -5.8 percentage points compared with the average across all models. This is a buying brief for the exact car in front of you: clean repeat history matters more than badge reputation.
- Repeat unresolved MOT notes for suspension and steering, windscreen, wipers, and mirrors, and emissions, engine, and exhaust
- suspension and steering appearing across more than one MOT
- Any dangerous MOT failure on the exact car, especially if the same area appears again later
- No paperwork showing applicable recall work has been completed
- A seller who cannot explain MOT wording such as "ball joint excessively worn"
It can be, if the exact car has a clean history for suspension and steering, windscreen, wipers, and mirrors, and emissions, engine, and exhaust.
Start with suspension and steering, windscreen, wipers, and mirrors, and emissions, engine, and exhaust, then compare the car's mileage and recall record below.
Suspension and steering is the clearest named problem area in the MOT history (9.6 MOT notes per 100 tests). These counts are issue notes, not failure rates, because a single MOT can list several faults.
Past 100k miles on the BMW X6, MOT records most often point to suspension and steering, emissions, engine, and exhaust, and lights and electrical.
The MOT failure rate rises from 33.3% at 0-3 years to 18.5% at 15+ years. Compare the car with the nearest age range before treating a fault as normal wear or a warning sign. The average MOT failure rate across all models in the same dataset is 18.7%.
Start with suspension and steering, windscreen, wipers, and mirrors, emissions, engine, and exhaust, and lights and electrical. The checklist on this page explains why each area is being recommended, what to inspect, and what to ask the seller.
6 relevant recall notices appear for this model. Treat them as safety checks to verify for the exact car, not as normal MOT wear.
