Electrical system:software
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2018-2019 Toyota Tundra and Sequoia vehicles and 2019 Toyota Avalon and Avalon Hybrid vehicles. The air bag electronic control unit (ECU) may erroneously detect a fault during the vehicle start-up self check. If this occurs, the ECU may not deploy the airbags as intended, in the event of a crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection," and 214, "Side Impact Protection."
Risk: If the air bags do not deploy as intended, it can increase the risk of injury in a crash.
Remedy: Toyota will notify owners, and dealers will update the software for the air bag ECU, free of charge. The recall began October 26, 2018. Owners may contact Toyota customer service at 1-888-270-9371. Toyota's number for this recall is J0X. Note: 18V-122 was superseded by this recall. The software remedy also includes the updates to the software for 18V-122.
