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, which can cause the airbags to deploy incorrectly during a crash.

What's the problem?

The recall affects about 168,187 vehicles. Due to inappropriate programming, the Airbag (SRS) ECU may erroneously detect a fault in one or more of the front or side SRS satellite sensors during a self-check that occurs at each vehicle start up. This condition will cause the vehicle to set a specific trouble code, disable the affected sensor(s), sound a warning buzzer, activate multiple warning lights, and display a message on the combination meter display.

If a fault is erroneously detected, the Airbag ECU may not appropriately identify the crash condition if a crash occurs, and the airbags may not deploy as intended. As a result, some requirements of FMVSS No. 208 and 214 may not be met, resulting in an increased risk of injury during a crash.

What happens next?

Toyota will notify owners and dealers will update the software for the air bag ECU free of charge. The recall is expected to begin October 22, 2018.

Owners may contact Toyota customer service at (888) 270-9371. Toyota's number for this recall is J0X.
