2 known faults

RZ 450e

  1. Windscreen demisting recall (air-conditioning software)

    Manufacturer recall

    Joint recall with the Toyota bZ4X, Lexus RZ 300e/450e and Subaru Solterra: a software fault in a control unit can prevent the windscreen from being demisted or defrosted and, in some cases, put the air conditioning into degraded mode, reducing visibility. Dealerships reprogram the control unit and check the compressor, free of charge. The recall was announced in the United States, Canada and South Africa; the exact scope for France is not confirmed by the sources: check with the VIN at Lexus.

    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).

  2. Battery control unit recall: loss of drive power

Free correction by reprogramming at a dealership. A separate recall exists in New Zealand (7 RZ 2025-2026). European scope not confirmed by the sources.

    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).
