Lexus Nx (2021)
2021 Lexus Nx
CarHunch analysed 4,277 real MOT records for the 2021 Lexus Nx. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 Lexus NX is a standout performer on the MOT test, with a 95.3% first-time pass rate that significantly outpaces the UK average of 80%—this is a genuinely reliable car. Only 3.2% of vehicles in this cohort have ever recorded a dangerous defect, which is well below concern threshold and reflects the quality you'd expect from a premium Japanese brand.
At a median mileage of just 25,381 miles for vehicles now three years old, these cars are running light, and the average of only 0.15 failures per vehicle confirms owners aren't encountering systemic issues. When you do see advisories (averaging 1.3 per car), they're typically minor wear items rather than structural problems—so if you're shopping for a used NX from this year, focus your pre-purchase inspection on the usual maintenance records rather than worrying about hidden mechanical gremlins.
What to check before buying a 2021 Lexus Nx
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.
