Most newer cars are equipped with a system that can detect whether or not a person is sitting in the front seat. If they are, the system will ensure that the airbags deploy in the event of a crash. But for 58,510 Toyota vehicles now being recalled that feature isn’t working correctly.

Toyota says it will recall 16,880 model year 2016 Avalon and 41,630 model year 2016 Camry sedans that contain airbags that might not deploy when necessary.

According to the carmaker, the front passenger seat’s occupant-classification system may not have received proper calibration during the vehicle manufacturing process.

The system activates or deactivates the front passenger air bag system, depending on the weight of the occupant.

With the improper calibration, under some conditions, the front passenger airbag and the front passenger knee airbag may not deploy as designed in a crash, increasing the risk of an injury to a front seat passenger.

Owners of the affected vehicles will be noticed by first class mail and dealers will re-calibrate the occupant classification system.
