Toyota will recall about 803,000 cars, including the Camry, Avalon and Venza, because of a problem that could inadvertently set off an airbag or shut down the power steering.
All of the affected cars are from the 2012 or 2013 model year. The hybrid versions of the Avalon and Camry are included in the recall.
Toyota said water from the air conditioning’s condenser unit housing could leak onto the airbag control module and cause a short circuit. That can trigger the airbag warning light and, in some instances, disable an air bag.
Two cases were reported in which an air bag unexpectedly deployed, causing minor injuries, the automaker said.
Also, the power steering assist function could become inoperable if a wire in the airbag control module is damaged.
Owners of affected cars will be notified by mail to return their vehicles to a Toyota dealer for repair.
