Should I check the MOT history before buying a 2021 BMW X5 Xdrive45e Xline Auto?

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 2021 BMW X5 Xdrive45e Xline Auto?

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 2021 BMW X5 Xdrive45e Xline Auto?

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.

Is the 2021 BMW X5 Xdrive45e Xline Auto reliable?

Based on MOT data from 316 vehicles, the 2021 BMW X5 Xdrive45e Xline Auto has a first-time MOT pass rate of 90.7%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2021 BMW X5 Xdrive45e Xline Auto?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

Moderate sample. 316 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

This 2021 BMW X5 hybrid plug-in is significantly more reliable than the UK average, with an 86.4% first-time pass rate against the 80% benchmark, and only 7.6% of vehicles have ever recorded a dangerous defect—well below the threshold for concern. The median mileage of 43,697 miles is reasonable for a three-year-old vehicle, suggesting these are genuinely well-maintained examples rather than run-hard fleet cars.

The real story is in the low failure count: 0.3 failures per vehicle means most owners aren't facing expensive repairs at MOT time, though the 1.1 advisories per vehicle hint at minor wear creeping in. If you're considering this model, get a pre-purchase inspection focused on the hybrid battery and electrical systems, since those are where the complexity—and cost—typically hide on plug-in hybrids.

The 2021 BMW X5 Xdrive45e Xline Auto passes its MOT first time more often than most UK vehicles (90.7% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ Around 1 in 20 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 90.7% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔍 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 316 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.
