4 known faults

1.0 TSI 110

  1. Temperamental multimedia and electronics

    Severity 1/3 · Annoying

    According to What Car?, 48% of the Leons surveyed had a fault, mainly in the multimedia system and non-engine electrics. Buying guides cite crashes and restarts of the MIB3 system on the first examples (2020-2021), largely corrected by software updates; French owners' reviews also mention electronic bugs that appear and then disappear.

    Versions
    1.0 TSI 110, 1.5 TSI 150, 1.5 eTSI 150 DSG7, 2.0 TDI 115, 2.0 TDI 150 DSG7, e-Hybrid 204 DSG6

  2. Recall: boot partition handle poorly fixed (Leon 2020-2022)

    Manufacturer recall

    Campaign 68I3: in a crash, luggage thrown forward can tear off the mounting bracket of the boot divider grille, which is poorly riveted, increasing the risk of injury. It concerns Leons built between July 2020 and June 2022 (11,110 cars according to one source); only the serial number shows whether a given car is affected.

    Fixed free of charge by a dealer and not counted in the reliability score: ask for proof the work was done (invoice, or a VIN check at a dealer).

    Versions
    1.0 TSI 110, 1.5 TSI 150, 1.5 eTSI 150 DSG7, 2.0 TDI 115, 2.0 TDI 150 DSG7, e-Hybrid 204 DSG6

  3. Recall: engine mounts can crack (Leons built on 27 and 28 July 2023)

    Manufacturer recall

    Campaign 10J3: incorrect heat treatment of the engine mounts can make them crack, affecting stability and increasing the risk of an accident. It concerns only Leons built on 27 and 28 July 2023 (258 vehicles worldwide according to one source); check by serial number.

    Owners of the Leon 1.5 TSI report jerks at low revs, especially when the engine is cold. A software update was offered by the manufacturer, but several owners report that the symptoms return after a few days.
