2020 Land Rover Defender S D Auto
CarHunch analysed 771 real MOT records for the 2020 Land Rover Defender S D Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2020 Defender S diesel auto is noticeably more reliable than the UK average, with an 89.3% first-time pass rate against the national 80%, and only 5.6% of vehicles ever flagged for dangerous defects—a reassuring figure for a used purchase. The low failure count of 0.27 per vehicle confirms these are mechanically sound units in their early years.
At a median mileage of 37,222 miles for a four-year-old vehicle, these Defenders are running light and show it: owners are averaging just 1.7 advisories per test, suggesting preventative maintenance is keeping problems at bay. When shopping, prioritise examples with complete service history and an advisory count below 2, as this cohort's strength lies in consistent upkeep rather than any inherent robustness.
What to check before buying a 2020 Land Rover Defender S D Auto
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.
