Lexus Is300: MOT pass rate and reliability data

The Lexus Is300 passes its MOT first time more often than the average UK car, by 2 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 761 individual Lexus Is300 tests. Nothing here is an estimate or a survey.

The numbers

What this means if you are buying one

A 78.7% first-time pass rate means roughly 21 in every 100 Lexus Is300s 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 Is300 tested had covered 113,911 miles and was built around 2005.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The Lexus Is300 sits 2 points above the national average, ranked 1,495 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 Is300 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 Is300s at UK salvage auction.

Most common MOT failures on a Lexus Is300

1. 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, 4.2% of tests (4.47x the national rate for this defect)
2. A tyre cords visible or damaged, 2.5% of tests (1.49x the national rate for this defect)
3. Windscreen washers not working or not providing sufficient fluid to clear the windscreen, 2.2% of tests (1.33x the national rate for this defect)
4. A suspension pin, bush or joint excessively worn, 3% of tests
5. Tyre tread depth not in accordance with the requirements, 2.9% of tests
6. A tyre seriously damaged, 2.6% of tests
7. The aim of a headlamp is not within limits laid down in the requirements, 2.6% of tests
8. A lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning, 2.4% of tests
9. A spring or spring component fractured or seriously weakened, 1.8% of tests
10. Significant brake effort recorded with no brake applied indicating a binding brake, 1.7% of tests (1.65x the national rate for this defect)

From 758 DVSA-tracked Lexus Is300 tests, 2024. DVSA testers marked 4.45% of these flagged Lexus Is300 defects as "dangerous", meaning the tester judged the car unsafe to drive away, against 5.11% nationally.

Most common MOT advisories on a Lexus Is300

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 Is300 before it actually fails on it.

1. 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, 9.1% of tests (6x the national rate for this advisory), also fails
2. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 6.5% of tests (5.2x the national rate for this advisory)
3. Product on the lens or light source which obviously reduces light intensity or changes emitted colour to other than white or yellow, 3.8% of tests (3.46x the national rate for this advisory)
4. A suspension component excessively damaged or corroded, 14.4% of tests (2.78x the national rate for this advisory)
5. Number plate inscription missing or illegible, 6.1% of tests (2.29x the national rate for this advisory)
6. Fluid leaking excessively and likely to harm the environment or to pose a safety risk to other road users, 11.6% of tests (2.09x the national rate for this advisory)
7. Significant brake effort recorded with no brake applied indicating a binding brake, 3% of tests (1.52x the national rate for this advisory), also fails
8. Brake pipe damaged or excessively corroded, 9.2% of tests (1.49x the national rate for this advisory)
9. A suspension pin, bush or joint excessively worn, 17.8% of tests (1.33x the national rate for this advisory), also fails
10. Tyre tread depth not in accordance with the requirements, 26.6% of tests, also fails
