Hyundai Sonata: MOT pass rate and reliability data

The Hyundai Sonata fails its first MOT more often than the average UK car, by 9.7 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 561 individual Hyundai Sonata tests. Nothing here is an estimate or a survey.

The numbers

What this means if you are buying one

A 67% first-time pass rate means roughly 33 in every 100 Hyundai Sonatas presented for MOT fail on the first attempt. That is worse than average, so budget for remedial work and treat a fresh 12-month MOT as a genuine selling point rather than a given. The average Hyundai Sonata tested had covered 89,029 miles and was built around 2007.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. On a Hyundai Sonata bought as a repairable salvage, assume the mechanical side needs more than the visible accident damage, and pad your repair estimate accordingly.

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 Hyundai Sonata 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 what damaged Hyundai Sonatas actually sold for at UK salvage auction.
