Should I check the MOT history before buying a 2021 Lexus Nx?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2021 Lexus Nx?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2021 Lexus Nx?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Is the 2021 Lexus Nx reliable?

Based on MOT data from 4,277 vehicles, the 2021 Lexus Nx has a first-time MOT pass rate of 95.3%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

These figures are based on actual MOT test records — search a specific registration on CarHunch to see its individual history.

Do I need an HPI check when buying a 2021 Lexus Nx?

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.

The 2021 Lexus Nx passes its MOT first time more often than most UK vehicles (95.3% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
