Used buying checklist
BMW X4 reliability, common problems and used buying checks
A used BMW X4 looks better than average for reliability in UK MOT data: 11.4% of 16,592 tests failed, compared with 18.7% across all indexed models. A good example should have a clean MOT history for windscreen, wipers, and mirrors, suspension and steering, and tyres and wheels.

Start with windscreen, wipers, and mirrors, suspension and steering, and tyres and wheels, then compare the car's mileage and recall record below.
Windscreen, wipers, and mirrors is the clearest named problem area in the MOT history (5.8 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 X4, MOT records most often point to suspension and steering, windscreen, wipers, and mirrors, and corrosion and structure.
The MOT failure rate rises from 10.3% at 0-3 years to 0.0% 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 windscreen, wipers, and mirrors, suspension and steering, tyres and wheels, 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.

Recall records and data freshness
Recall context: are there safety notices to know about?
6 relevant recall notices appear for this model. Treat them as safety checks to verify for the exact car, not as normal MOT wear.
| 2026-03-02 | Replace the Engine Starter Motor The Safety Recall relates to the engine starter motor. The fault relates to the RSW22 starter RWT (reinforced water tightness). It was found that with RWT starters an increased abrasion of the magnetic contact can cause the growth of deposits at the lowest point of the relay interior. This in turn may increase the relay contact resistance resulting in false starts or even causing short circuits and possibly a thermal reaction. In case of a short circuit the possibility of a thermal event cannot be excluded. This may happen while attempting to start the vehicle or while driving due to vibrations causing a short circuit due to moving deposits. On the affected vehicles the starter motor will be replaced with a variant by another supplier with a different design. Until the repair has been completed it is recommended to not leave the vehicle running unattended after starting the engine. |

| 2024-10-21 | Check Driver’s Airbag for Conversion Takata SDI & PSDI-5 Affected vehicles may have had a retrofit or conversion of the airbag using a previously recalled airbag variant which if deployed may do so with excessive force causing sharp metal fragments to be released this may cause serious injury possibly fatal to people in the vicinity.
