Should I check the MOT history before buying a 2020 Lexus Ux?

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 2020 Lexus Ux?

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 2020 Lexus Ux?

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.

Based on MOT data from 3,884 vehicles, the 2020 Lexus Ux 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.

The 2020 Lexus UX is a genuinely reliable car, with a 95.3% first-time MOT pass rate that sits well clear of the UK average of 80%—and only 5.9% of vehicles have ever recorded a dangerous defect, which is reassuringly low. The hybrid powertrain appears to be delivering on its promise, with minimal failures averaging just 0.2 per vehicle.

At around 27,000 miles median for a four-year-old car, these UX models are running below average mileage, which partly explains the strong results, but the real story is the build quality and engineering—owners are averaging only 1.5 advisories per test, suggesting components are wearing well. If you're considering one, focus your pre-purchase inspection on the hybrid battery system and cooling components, but the MOT data gives you confidence you're looking at a fundamentally sound vehicle.

The 2020 Lexus Ux 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.

⚠️ Around 1 in 20 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

✅ Good baseline reliability. A 95.3% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 1.5 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 3,884 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
