GENERAL MOTORS issued a recall on the IMPALA model

Certain vehicles equipped with front vented-heated passenger seats may not comply with the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 208 - Occupant Protection. The Automatic Occupant Sensing (AOS) system may contain a calibration-learning error that will cause the AOS system to fail to suppress the front passenger airbag when an infant seat is placed in the front passenger seat. The front-passenger airbag status light will indicate that the airbag is “on” when the passenger seat is not occupied or is occupied by an infant. Additionally, the front-passenger seat’s safety-belt warning light and chime may turn on when the passenger seat is not occupied and the seatbelt is not buckled. If, despite safety warnings and provincial regulations, a child was placed in a child car seat secured in the passenger front position, the active airbag could deploy in a crash causing potential injury. Correction: Dealers will correct the calibration-learning error by preconditioning the empty seat and resetting the seat zero-value in the ECU.
