Failure rate by age

The line to watch is the red one. Dashed lines are petrol and diesel cars of the same age, tested the same year.

    Points are hidden where fewer than 50 cars of that age were tested.

    Where it holds up

    • Suspension fail less often than on petrol and diesel cars (0.7% of defects vs 13.6%)
    • Brakes fail less often than on petrol and diesel cars (2.2% of defects vs 18.7%)
    • Lighting fail less often than on petrol and diesel cars (4.9% of defects vs 16.5%)
    • Steering fail less often than on petrol and diesel cars (0.2% of defects vs 3.1%)

    Where it fails

    • Tyres take a bigger share of failures than on the wider fleet (69.9% vs 23.7%)
    • At three years old it fails 9.7% of the time, above the 8.2% of petrol cars the same age

    What fails, by system

    Share of all defects that caused a failure. The dark mark is the same system on petrol and diesel cars of the same age.

    Top defects on the certificate

    Wording from the DVSA inspection manual, so it matches what a tester writes.

    1. A tyre seriously damaged688
    2. A tyre cords visible or damaged544
    3. Tyre tread depth not in accordance with the requirements518
    4. Number plate does not conform to the specified requirements171
    5. Windscreen or window damaged or seriously discoloured but not adversely affecting driver's view83
    6. Wiper blade missing or obviously not clearing the windscreen54

    Check before you buy

    • Check tyre age and tread across the full width, inner edge included. Electric cars wear tyres faster; a cheap mismatched set on a used car tells you how it was run.
    • Trivial to fix, but a car advertised with worn wipers and a fresh failure certificate tells you how it was maintained.
    • Ask for the full MOT history by registration on the free DVSA service: advisories are next year's failures.

    What owners say about the same faults

    No owner discussion has been matched to this car's recorded defects yet. Reports are re-collected every quarter; the figures on this page do not depend on them.

    Summaries written by us, never quotes; every entry links to its source. Owner reports have no denominator and never feed the failure rate.

    Three things the data shows

    • 14,319 inspections in 2024 make this one of the best-documented electric cars in the data.
    • Tyres take 2.9× the share of failures they take on petrol and diesel cars of the same age.
    • Failure rate rises from 8.1% at 4 years to 10.5% at 5: a gentle ageing curve.

    What the inspection does not tell you

    No battery health, no motor, no charging performance. The test covers brakes, suspension, steering, tyres, lights, visibility and structure. A car with a badly degraded battery passes as long as it stops and steers. Read this page as evidence about the chassis, not the powertrain.

    Cars are tested from their third year, so the newest model years are missing. Every figure carries its sample size for that reason. Full methodology.
