Lexus Ls430: MOT pass rate and reliability data

The Lexus Ls430 passes its MOT first time more often than the average UK car, by 5.3 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 1,053 individual Lexus Ls430 tests. Nothing here is an estimate or a survey.

The numbers

What this means if you are buying one

A 82% first-time pass rate means roughly 18 in every 100 Lexus Ls430s 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 Ls430 tested had covered 128,455 miles and was built around 2003.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The Lexus Ls430 sits 5.3 points above the national average, ranked 1,379 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 Ls430 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 Ls430s at UK salvage auction.

3. Exhaust system leaking or insecure, 2.1% of tests (2.07x the national rate for this defect)
4. Engine MIL illuminated indicating a malfunction, 2.5% of tests (1.93x the national rate for this defect)
5. Parking brake efficiency below minimum requirement, 2.1% of tests (1.61x the national rate for this defect)
6. The aim of a headlamp is not within limits laid down in the requirements, 3.4% of tests (1.46x the national rate for this defect)

Most common MOT advisories on a Lexus Ls430

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 Ls430 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, 7.4% of tests (4.88x the national rate for this advisory), also fails
2. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 4.1% of tests (3.29x the national rate for this advisory)
3. Excessive fluctuation in brake effort through each wheel revolution., 2.8% of tests (3.25x the national rate for this advisory)
4. Exhaust system leaking or insecure, 8.1% of tests (2.84x the national rate for this advisory), also fails
5. Product on the lens or light source which obviously reduces light intensity or changes emitted colour to other than white or yellow, 3.1% of tests (2.83x the national rate for this advisory)
6. A suspension component excessively damaged or corroded, 13.9% of tests (2.68x the national rate for this advisory)
7. Fluid leaking excessively and likely to harm the environment or to pose a safety risk to other road users, 10.6% of tests (1.9x the national rate for this advisory)
8. A shock absorber damaged to the extent that it does not function or showing signs of severe leakage, 6.5% of tests (1.65x the national rate for this advisory)
9. A suspension pin, bush or joint excessively worn, 21% of tests (1.57x the national rate for this advisory)
10. Brake pipe damaged or excessively corroded, 8.1% of tests (1.3x the national rate for this advisory)
