The defect
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 remedy
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.

What this page is, and what to do next
A recall is not an opinion. It is a Part 573 report a manufacturer is required by federal law to file once it decides a defect poses an unreasonable risk to safety, and it commits them to repairing the vehicle at no cost to the owner. The three passages above are the manufacturer’s own wording as published by NHTSA.
This page describes the campaign. It cannot tell you whether one particular car has already been through the shop — that is tracked by VIN, and only the manufacturer knows it. Check yours at nhtsa.gov/recalls or with a franchised dealer, quoting campaign number 23V041000.
