Toyota Australia Recalls bZ4X Vehicles Due To Electric Compressor

Toyota Australia has today announced that it will initiate a safety recall involving certain bZ4X vehicles produced between 26th October 2023 – 10th June 2025 (inclusive). Of these vehicles, some also have a Customer Service Exercise for bZ4X vehicles produced between 14th January 2025 – 10th June 2025 (inclusive). Overall there are 2,166 vehicles involved in the Australian market.

The involved vehicles are equipped with Heating, Ventilation, and Air Conditioning (HVAC) systems that, among other things, control the windshield defroster function. Due to the programming of the HVAC control ECU software, under certain conditions, such as a specific failure mode of the electrical compressor, the HVAC system will enter a failsafe mode that suspends the heater operation of the system and affects defroster function. In some cases, when the vehicle is operated in certain low temperatures, the defrosting performance reduces and may not remove frost, ice and/or fog from the windshield glass. This can reduce driver visibility and increase the risk of a collision in certain driving conditions.

For all involved vehicles, Toyota will update the A/C ECU software and inspect/replace the Electric Compressor if required, free of charge to owners.

Completion of this recall will take approximately 1-4 hours depending on if replacement of the Electric Compressor is required. Depending on the Dealer's work schedule, owners may be required to make the vehicle available for a longer period of time.

Toyota Australia will contact all owners of involved vehicles to provide details of this safety recall campaign. Owners are asked to keep their contact details up to date with Toyota so future communications can be received.

Owners with additional questions or concerns are asked to please contact their local/preferred Toyota Dealer in the first instance or the Toyota Recall Campaign Helpline on 1800 987 366 (Mon-Fri 8.00am-7.00pm AEST). Please quote your 17-digit Vehicle Identification Number (VIN).
