Used buying checklist

BMW 7 Series reliability, common problems and used buying checks

A used BMW 7 Series looks better than average for reliability in UK MOT data: 10.1% of 3,812 tests failed, compared with 18.7% across all indexed models. A good example should have a clean MOT history for suspension and steering, emissions, engine, and exhaust, and windscreen, wipers, and mirrors.

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.

• 10.1% MOT failure rate
• Median tested mileage 61,992 miles
• 383 failed MOT tests analysed

90.0% of the MOT tests we analysed for this model passed. The model's recorded failure rate is 10.1%, -8.7 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.

Better than average in our MOT data

Green light if The car has a tidy MOT pattern, recent repairs for suspension and steering, emissions, engine, and exhaust, and windscreen, wipers, and mirrors, matching tyres, and paperwork for service or recall work.

Renegotiate if The latest MOT mentions suspension and steering, emissions, engine, and exhaust, and windscreen, wipers, and mirrors, consumables are due together, or the seller cannot show what was fixed after advisories.

Walk away if Dangerous defects, corrosion near structural areas, warning lights, or the same component family keep returning without clear repair evidence.

• Repeat unresolved MOT notes for suspension and steering, emissions, engine, and exhaust, and windscreen, wipers, and mirrors
• 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"
