Lexus Rx (2020)
2020 Lexus Rx
CarHunch analysed 1,781 real MOT records for the 2020 Lexus Rx. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2020 Lexus RX is exceptionally reliable, with a 96.5% first-time MOT pass rate that sits well above the 80% UK average—this is a genuinely strong result. Only 4.8% of vehicles in this cohort have ever recorded a dangerous defect, which is reassuringly low and well below the typical concern threshold.
At just over 28,000 miles on the median vehicle, these cars are still relatively young and lightly used, which partly explains the strong reliability picture. The average of just 0.14 failures per vehicle and 1.6 advisories per vehicle indicates that when issues do crop up, they're typically minor—so when you're shopping for one, focus your inspection on service history and any accident damage rather than expecting mechanical gremlins.
What to check before buying a 2020 Lexus Rx
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.
