2022 Model Year Prius and Prius Prime Vehicles Vehicle May Lose Motive Power While Driving


On September 22, 2021, Toyota filed a Defect Information Report (DIR) with the National Highway Traffic Safety Administration (NHTSA) informing the agency of our intent to conduct a voluntary Safety Recall on certain 2022 model year Prius and Prius Prime vehicles

Condition:
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 if the position changes during a short window of time when the computer is checking this information. If this occurs, warning lights will illuminate and the hybrid system will shut down resulting in loss of motive power while driving. If the vehicle loses motive power while being driven at a higher speed, there could be an increased risk of a crash.

Remedy:
Toyota is currently preparing the remedy. When the remedy is available, any authorized Toyota dealer will update the hybrid vehicle ECU software to correct the programming in the hybrid vehicle ECU’s shift monitoring logic FREE OF CHARGE.

Covered Vehicles:
There are approximately 8,500 vehicles covered by this Safety Recall. None of the vehicles covered by this Safety Recall were distributed to Puerto Rico.

Owner Letter Mailing Date:
Toyota will notify owners by late November 2021.

Salvage Title Vehicles:
Every attempt should be made to complete an open Safety Recall when circumstances permit, unless noted otherwise in the Safety Recall dealer letter.

Loaner Vehicle or Alternative Transportation Reimbursement Procedure Until the remedy is available, customers who are uncomfortable driving their vehicle during the interim phase may receive a loaner vehicle or alternative transportation through Toyota Rent-A-CAR (TRAC)
