Measured at MOT: how a 2023 Leon fails more often

Based on 19,139 first MOT tests of this model at 3 years old (cars first used 2021–2022), compared against every car of the same age and fuel.

Nothing stands out. No category fails clearly more often on this model than on cars of the same age and fuel.

    How to read this

    These are MOT outcomes for other cars of the same model, age and fuel — not a prediction about this one, and not a fault diagnosis. A high rate means the category is worth checking, not that this car has a problem.

    A comparison is only shown where it survives its own margin of error. Where a model is only slightly above average, both rates are shown and no multiple is given, because the data cannot tell the difference.

    MOT results reflect how a car has been used and maintained as much as the model itself. High mileage, short journeys and deferred servicing all show up here.

        On some 2011-built diesel SEATs with stop-start, a bent or broken return spring in the starter solenoid could leave the starter motor powered permanently. If unnoticed, the starter could overheat, scorch nearby parts and in the worst case start a fire. Dealers replace the solenoid switch.

        Only diesels with stop-start were affected; DVLA does not record stop-start. A SEAT dealer can confirm from the VIN whether this car was included and whether the work has been done.

        MOT failure rate: the Leon against vehicles its age

        In our analysis of DVSA's anonymised MOT data for 2024 and 2025, 24.3% of 358,095 initial MOT tests on the SEAT Leon failed at the first attempt — 7% less often than vehicles of the same ages and fuel types, which failed 26.1%.

        Common questions

        What are the most common Leon problems?

        For cars built from 2012, the problems at least two independent publishers report include: Infotainment screen glitches, freezes and failures; 7-speed dry-clutch DSG (DQ200): judder, clutch wear, mechatronic; Water and condensation inside the rear light clusters; Minor electrical faults. Which apply depends on the generation and engine — they are listed generation by generation above, each with its sources.

        Has the Leon been recalled?

        Yes. DVSA lists recalls for the Leon built from 2012, shown above by generation. A recall covers a range of chassis numbers, so not every car is affected — check a specific car by VIN on GOV.UK, or by registration with our checker.

        Does my Leon have these problems?

        Not necessarily. These describe the model; many cars never have them, and a well-maintained car is less likely to. Enter your registration above to see the problems for your exact generation and engine, and whether DVSA records an outstanding recall on it. Whether a known problem was fixed is what a service history check shows.

        Has this Leon had the work done?

        A known problem matters far less on a car whose dealer records show it was fixed. A service history check returns the manufacturer's own dealership records for a specific car — and there's no charge if we find nothing.
