Prius Plus: above-average pass rates, with caveats

Across 3,637 MOT tests, the Prius Plus returns 82.6% first-time pass — above the UK fleet average. The single most-logged Major fail is tyre tread under the limit. A number-plate lamp out and brake pads worn below 1.5 mm round out the top three. Average tested mileage sits at 120,403, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.
