Toyota Australia Initiates Customer Service Exercise For Electric Heater On Mirai

Toyota Australia has today announced that it will initiate a Customer Service Exercise (CSE) for the Electric Heater on a range of Toyota Mirai vehicles produced between 3rd June 2021 – 2nd November 2023. There are approximately 41 vehicles involved in the Australian market.

The subject vehicles are equipped with Heating, Ventilation, and Air Conditioning (HVAC) systems containing an electric heater. Due to insufficient heater durability, there is a possibility that the electric heater could fail when exposed to stress over time, causing heater operation to become inoperative. When the vehicles are operated in certain low temperatures, the heater performance may reduce, but the defrosting performance remains operational, and no unreasonable risk to safety is presented.

For all involved vehicles, Toyota dealers will replace the Electric Heater, free of charge to owners.

Repair and inspection will take approximately 3 hours. 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 CSE 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 Campaign Helpline on 1800 987 366 (Mon-Fri 8.00am-6.00pm AEST). Please quote your 17-digit Vehicle Identification Number (VIN).
