Toyota Iq: MOT pass rate and reliability data

The Toyota Iq passes its MOT first time more often than the average UK car, by 4.8 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 17,007 individual Toyota Iq tests. Nothing here is an estimate or a survey.

The numbers

What this means if you are buying one

A 81.5% first-time pass rate means roughly 19 in every 100 Toyota Iqs 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 Toyota Iq tested had covered 69,430 miles and was built around 2010.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The Toyota Iq sits 4.8 points above the national average, ranked 1,395 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 Toyota Iq 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 the median recorded closing bid for a damaged Toyota Iq: £500 at UK salvage auction, from 5 ended listings, not independently confirmed sales.

2. Brake pipe damaged or excessively corroded, 2.2% of tests (2.1x the national rate for this defect)
3. Wiper blade missing or obviously not clearing the windscreen, 2.6% of tests (1.39x the national rate for this defect)

Most common MOT advisories on a Toyota Iq

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 Toyota Iq before it actually fails on it.

1. A brake hose ferrule excessively corroded, 5.4% of tests (4.22x the national rate for this advisory)
2. Product on the lens or light source which obviously reduces light intensity or changes emitted colour to other than white or yellow, 3.9% of tests (3.55x the national rate for this advisory)
3. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 2.5% of tests (2.04x the national rate for this advisory)
4. 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, 3% of tests (1.99x the national rate for this advisory)
5. Brake pipe damaged or excessively corroded, 11.5% of tests (1.86x the national rate for this advisory), also fails
6. A spring or spring component fractured or seriously weakened, 7.4% of tests (1.56x the national rate for this advisory)
7. Exhaust system leaking or insecure, 4.4% of tests (1.54x the national rate for this advisory)
8. Significant brake effort recorded with no brake applied indicating a binding brake, 3.1% of tests (1.54x the national rate for this advisory)
9. A tyre seriously damaged, 22.3% of tests (1.44x the national rate for this advisory), also fails
