Should I check the MOT history before buying a 2018 BMW X5?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2018 BMW X5?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2018 BMW X5?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

The 2018 BMW X5 passes its MOT on the first attempt 85% of the time, a solid 5 percentage points above the UK average, though the 21.1% rate of dangerous defects is a genuine concern—roughly one in five vehicles has recorded at least one serious safety issue. Diesel models (which make up 89% of the cohort) perform best at 85.9% pass rate, while the hybrid variant lags significantly at 72.9%, suggesting electrified drivetrains in this generation carry higher fault risk.

At under 50,000 miles on average for a six-year-old car, these X5s show relatively light use, yet each vehicle averages 0.69 failures and 4.0 advisories per test—pointing to age-related wear rather than abuse. Before committing to purchase, budget for brake and suspension checks, as these are the dominant advisory categories on large SUVs, and insist on a full service history to catch any hidden electrical gremlins common to high-mileage luxury vehicles.

The 2018 BMW X5 passes its MOT first time at roughly the UK average rate (89.1%) — solid but worth checking this vehicle's history carefully.

⚠️ 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 89.1% 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 4 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 7,571 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.
