23V865000 Dec 20, 2023 AIR BAGSToyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2020-2021 Avalon, Avalon Hybrid, Corolla, Highlander, Highlander Hybrid, RAV4, RAV4…

Summary: Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2020-2021 Avalon, Avalon Hybrid, Corolla, Highlander, Highlander Hybrid, RAV4, RAV4 Hybrid, Lexus ES350, Lexus RX350, Lexus RX450H, 2021 Sienna Hybrid, Lexus ES250, 2020-2022 Camry, Camry Hybrid, and ES300H vehicles. A short circuit may develop in the Occupant Classification System (OCS) sensor, preventing the front passenger air bag from deploying.

Consequence: An air bag that does not deploy during a crash increases the risk of injury.

Remedy: Dealers will inspect and replace the sensor as necessary, free of charge. Interim letters notifying owners of the safety risk were mailed in February 2024. Some final remedy owner letters were mailed October 31, 2024. Letters will continue to be mailed in phases through January 2026. Owners may contact Toyota customer service at 1-800-331-4331.

20V734000 Nov 25, 2020 AIR BAGS; STEERINGToyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2020-2021 Toyota Avalon and 2020 Avalon Hybrid, RAV4, and RAV4 Hybrid vehicles.

Summary: Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2020-2021 Toyota Avalon and 2020 Avalon Hybrid, RAV4, and RAV4 Hybrid vehicles.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "Occupant Crash Protection."

Consequence: 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.

20V064000 Feb 6, 2020 ENGINE AND ENGINE COOLINGToyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2020 Toyota Avalon Hybrid, Camry, Camry Hybrid and Lexus ES300h and 2019-2020 RAV4 and…

Summary: Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2020 Toyota Avalon Hybrid, Camry, Camry Hybrid and Lexus ES300h and 2019-2020 RAV4 and RAV4 Hybrid vehicles equipped with 2.5L 4-Cylinder engines.

Additionally, for all involved vehicles, the engine may get damaged mechanically, possibly resulting in an engine oil leak, increasing the risk of a fire.

Remedy: Toyota will notify owners, and dealers will inspect and replace the engine including the engine block, as necessary, free of charge. The recall began April 3, 2020. Owners may contact Toyota customer service at 1-888-270-9371 or Lexus at 1-800-255-3987. Toyota's number for this recall is 20TA04. Lexus' number for this recall is 20LA02.
