All generations and engines together · 2,071 MOT tests in the 2025 data
Computed from DVSA MOT results, all of Great Britain, 2025. Nothing here is opinion.

Tyres, pads and stone chips say more about how the car was driven and maintained than about how it was built.
Owner folklore from forums and the motoring press. Most of it never shows up in an MOT, which is why this section exists at all.
The X7 rides on twin-axle self-levelling air suspension as standard, and owners on the BMW forums report sagging corners, uneven ride height and noisy or failing compressors, sometimes needing a full self-levelling pump or air strut replacement. The measured MOT data backs this up in a general sense: suspension is the standout fault category for this model. Whether it is the air struts themselves or the linkages and bushes around them wearing first varies by report, but the system is complex and expensive compared with steel springs.
The xDrive50i/M50i's twin-turbo 4.4-litre N63 V8 is a long-standing BMW family with a reputation for burning oil between services and, on the higher-mileage older versions of this engine, for timing chain guides wearing and rattling. The G07 uses an updated N63 but the same weak points are reported by specialist workshops. Watch for a heavy oil top-up requirement and a rattle on cold start; a chain and guide job runs well into four figures if it is needed.
BMW recalled a range of 2019-2021 models including the X7 over a steering rack where the pinion teeth could break under load, risking a loss of steering control. This was a free dealer fix under recall, not a buyer cost, but it is worth checking any pre-owned car actually had the work done.
BMW's integrated brake (IB) control module, used across recent X7 model years, has been the subject of several separate recalls for welds or software faults that can cause a loss of power brake assist or knock out ABS/DSC. It is a manufacturer-acknowledged design and build issue that has recurred across multiple model years rather than a one-off fix, so check the car's recall history rather than assuming an older recall covers a newer build.
On 2019-2022 X7s with the third row fitted, the compression springs that lock the seatback upright could be missing or badly installed, letting the backrest fold forward in a crash. BMW recalled affected cars for a free inspection and repair. It costs nothing if outstanding, but it is worth confirming a used car has had the work done and that the third-row seats lock solidly.
More recent X7s have been recalled after repeated start attempts were found to overheat the starter motor, with a small fire risk. It mainly affects cars that have had trouble starting first time and been cranked repeatedly, so it is more of a knock-on risk than a wear item, but it shows the starter and its wiring are worth checking on any car that has a history of slow or repeated starts.
