Verdict

Good choice, check first

Well-protected compact (5 stars Euro NCAP in 2020) with a mechanical package judged sound by buying guides, but with temperamental electronics: according to What Car?, nearly half of the Leons surveyed had a fault, mainly multimedia and non-engine electrics. Check the software version and the recalls by serial number.

Known faults

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.

Cold hesitation of the 1.5 TSI ("kangaroo")

Severity 1/3 · Annoying

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.

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.

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).

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).

Inspection checklist

Things to check

  • Test the multimedia screen at length, CarPlay/Android Auto and the air conditioning, and ask for the software version of the system.
  • Have a Seat dealer check, using the serial number, campaigns 68I3 (boot partition) and 10J3 (engine mounts).
  • 1.5 TSI: start with a cold engine and drive at low revs to detect jerks.
  • e-Hybrid: test charging from a socket and a wallbox.
  • Check the service book and invoices, and read the fault codes.

Questions to ask the seller

  • Have multimedia software updates been carried out, and have electronic faults been dealt with under warranty?
  • Have the manufacturer's recalls (68I3, 10J3) been checked using the serial number?

Test-drive tip: read the fault codes

A warning light that is off proves nothing: a fault may have been cleared just before the viewing. A Bluetooth OBD2 scanner, plugged in under the steering wheel and read on your phone, shows stored codes and whether all emissions readiness tests have run since the last reset.
