Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2011-2019 Corolla, 2011-2013 Matrix, 2012-2018 Avalon, and 2013-2018 Avalon Hybrid vehicles. During certain crashes, the air bag electronic control unit (ECU) may malfunction, possibly disabling the deployment of the air bags and/or seat belt pretensioners.
Consequence: In the event of a crash, air bags and/or seat belt pretensioners that do not deploy as intended may increase the risk of injury.
Remedy: Toyota will notify owners, and dealers will inspect the ECU and install a noise filter between the air bag control module and its wire harness, as necessary, free of charge. Owners were notified of the safety risk beginning March 2, 2020. A second letter notifying owners of the remedy repair will be mailed between March 16, 2020 and June 27, 2020.
