Should I check the MOT history before buying a 2018 Lexus Rx?

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 2018 Lexus Rx?

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 2018 Lexus Rx?

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.

The 2018 Lexus RX is a genuinely reliable prospect, passing its MOT first time in 95.7% of cases — nearly 16 percentage points above the UK average of 80%. Dangerous defects are rare, affecting just 7.3% of the fleet, so safety isn't a concern here.

At 35,400 miles median, these are lightly used examples for their age, which largely explains why they sail through testing with only 0.26 failures per vehicle on average. When shopping for one, focus on full service history and any advisories around suspension wear, but a well-maintained example should give you years of hassle-free motoring.

The 2018 Lexus Rx passes its MOT first time more often than most UK vehicles (95.7% 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 95.7% 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 2.9 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 1,964 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.
