PLANO, Texas (September 22, 2021) – Toyota is conducting a safety recall involving certain 2022 Prius and Prius Prime vehicles in the United States. Approximately 8,400 vehicles are involved in this recall.

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.

For all involved vehicles, Toyota dealers will update the hybrid vehicle ECU software to correct the programming in the hybrid vehicle ECU’s shift monitoring logic. Owners of vehicles will be notified by November 21, 2021.

Information about automotive recalls, including but not limited to the list of involved vehicles, is current as of today’s filing date and is subject to change thereafter.  To see if your vehicle is involved in a safety recall visit or and enter your Vehicle Identification Number (VIN) or license plate information.
