    Steering:column

    Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2020-2021 Toyota Avalon and 2020 Avalon Hybrid, RAV4, and RAV4 Hybrid vehicles. Breakaway pins within the steering column, designed to absorb energy and reduce injury during a crash, could have been damaged during production, possibly affecting the performance of the driver's air bag in the event of a crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "Occupant Crash Protection."

    Risk: In the event of a crash, an air bag that does not perform as designed can increase the risk of injury.

    Remedy: Toyota will notify owners, and dealers will replace the steering column, free of charge. The recall began December 18, 2020. Owners may contact Toyota customer service at 1-800-331-4331. Toyota's number for this recall is 20TB17/20TA17.
