502 real MOT outcomes analysed • 82.9% first-time pass rate

2021 BMW X5

CarHunch analysed 502 real MOT records for the 2021 BMW X5. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2021 BMW X5 is a reliably built SUV, with an 82.9% first-time pass rate that sits above the UK average of 80%—and diesel variants perform even better at 86.4%. Only 7.8% of these vehicles have ever recorded a dangerous defect, which is reassuringly low and shouldn't be a major concern for buyers.

At a median mileage of 34,259 miles for a three-year-old model, these cars are running well within typical expectations, and the low average of just 0.23 failures per vehicle confirms they're holding up. When you do take one in for its MOT, expect to pick up around 1.1 advisories on average—mostly minor wear items—so budget for routine maintenance but don't expect costly surprises if you're buying one that's been properly serviced.

What to check before buying a 2021 BMW X5

Practical pre-purchase checks for this age and model.

  • 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
  • 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
  • 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
  • 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
