Air bags: frontal
- What is wrong
- Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2020-2021 Toyota Avalon and 2020 Avalon Hybrid, RAV4, and RAV4 Hybrid vehicles.

- 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.
