The problem
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2021 RAV4 Prime Plug-In Hybrid vehicles. During certain cold weather driving conditions, while driving in EV Mode, the hybrid vehicle control engine control unit (HEV ECU) software may cause the hybrid system to shut down if the accelerator is rapidly pressed to further accelerate the vehicle, resulting in a stall.
The risk
An engine stall increases the risk of a crash.
The fix
Dealers will update the HEV ECU software, free of charge. Owner notification letters are expected to be mailed February 27, 2023. Owners may contact Toyota's customer service at 1-800-331-4331. Toyota's number for this recall is 23TA01.
