Toyota Australia recalls Prius vehicles due to hybrid control ECU software

Toyota Australia has today announced that it will initiate a safety recall involving Prius vehicles produced between June 2021 – July 2021. There are 17 vehicles involved in the Australian market, of which 7 have been delivered to customers.

In the involved vehicles, a software error can cause a control computer (hybrid vehicle ECU) to erroneously determine that it does not have the correct information about the transmission position. This can occur if the shift position is changed during a short window of time when the computer is checking the system status.

In this instance, warning lights will illuminate and the hybrid system will shut down resulting in loss of motive power. If the vehicle loses motive power while being driven at a higher speed, this could increase the risk of a crash.

For all involved vehicles, Toyota dealers will reprogram the hybrid control ECU software free of charge to vehicle owners.

It is expected that the remedy will take approximately 1 hour. However, the Dealer’s work schedule may require the owner to make the vehicle available for a longer period of time.
