The parking assist electronic control unit (ECU) software may prevent transmission of the rearview camera signal during cold weather, preventing the rearview image from displaying. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."
Dealers will reprogram the parking assist ECU software, free of charge. Owner notification letters are expected to be mailed May 30, 2022.
Toyota's number for this recall is 22TA04.
