BMW X3 (2020)
2020 BMW X3
CarHunch analysed 5,227 real MOT records for the 2020 BMW X3. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2020 BMW X3 is a reliably built SUV, with an 89.7% first-time pass rate that comfortably beats the UK average of 80%—petrol versions perform marginally better at 91.6% versus diesels at 88.8%, though both are above average. Only 9.7% of vehicles have ever recorded a dangerous defect, which is reassuringly low and suggests structural integrity across the cohort.
These cars are running at sensible mileages for their age, with a median of 34,431 miles, and typically need just 0.33 failures rectified per test. The average of 1.9 advisories per vehicle suggests minor wear and tear is normal, but nothing alarming—if you're considering buying one, have a pre-purchase inspection focus on suspension and brake components, as these tend to show up in advisory notes across this model.
What to check before buying a 2020 BMW X3
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.
