Lexus Is250: MOT pass rate and reliability data

The Lexus Is250 passes its MOT first time more often than the average UK car, by 3.3 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 9,646 individual Lexus Is250 tests. Nothing here is an estimate or a survey.

The numbers

What this means if you are buying one

A 80% first-time pass rate means roughly 20 in every 100 Lexus Is250s presented for MOT fail on the first attempt. That is better than average, so a well-kept example is a reasonably safe used buy. The average Lexus Is250 tested had covered 102,328 miles and was built around 2008.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The Lexus Is250 sits 3.3 points above the national average, ranked 1,443 of 2,005 models. On one bought as repairable salvage, the mechanical side is less likely to spring surprises, so your repair estimate should hold up reasonably well.

Before you bid: run the lot through the analyzer, check the car's own record, check the mileage, decode the VIN, and if it carries a marker use the write-off value calculator. Or compare it against another model.

Looking at a specific Lexus Is250 rather than the model in general? The free check covers its MOT and mileage history, and the full HPI report confirms the insurance write-off category, outstanding finance and whether it is recorded stolen, from licensed data for 5 credits. Already own one that has been damaged? Work out whether fixing it beats selling it with the repair or scrap calculator, and see recorded closing bids for damaged Lexus Is250s at UK salvage auction.

From 9,640 DVSA-tracked Lexus Is250 tests, 2024. DVSA testers marked 5.61% of these flagged Lexus Is250 defects as "dangerous", meaning the tester judged the car unsafe to drive away, against 5.11% nationally.

Most common MOT advisories on a Lexus Is250

An advisory doesn't fail the car - the tester flags it as worth watching, but it still passes. A different list from the failures above: what testers are noting on a Lexus Is250 before it actually fails on it.

1. Product on the lens or light source which obviously reduces light intensity or changes emitted colour to other than white or yellow, 7.5% of tests (6.76x the national rate for this advisory), also fails
2. Excessive fluctuation in brake effort through each wheel revolution., 2.3% of tests (2.67x the national rate for this advisory)
3. Exhaust system leaking or insecure, 6.4% of tests (2.25x the national rate for this advisory), also fails
4. Number plate inscription missing or illegible, 5.7% of tests (2.15x the national rate for this advisory)
5. The strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, 2.6% of tests (1.69x the national rate for this advisory)
6. A suspension component excessively damaged or corroded, 8% of tests (1.56x the national rate for this advisory)
7. A shock absorber damaged to the extent that it does not function or showing signs of severe leakage, 5.6% of tests (1.43x the national rate for this advisory), also fails
8. Brake disc or drum significantly and obviously worn, 4.4% of tests (1.39x the national rate for this advisory)
