The 2015 BMW X4 passes its MOT on the first attempt 86.1% of the time, which is a solid 6 percentage points above the UK average—but the real concern is that 36.9% of these vehicles have experienced a dangerous defect at some point, well above the threshold that should worry a buyer. This is a reliability red flag that warrants a pre-purchase inspection from a BMW-specialist mechanic.

At just over 59,000 miles median, these cars are showing average mileage for their age, which is reassuring. However, the 8.0 advisories per vehicle suggests ongoing maintenance costs, and with 1.38 failures per MOT cycle, you're looking at regular repair work beyond routine servicing. Before committing to one, get a full history check and budget for potential suspension, brake, and electrical work—typical BMW weak points.

The 2015 BMW X4 has a decent first-time pass rate (86.1%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

✅ Good baseline reliability. A 86.1% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 8 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 2,220 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
