General Motors have decided that a defect relating to motor vehicle safety exists in certain 2009-2010 Chevrolet Impala vehicles. The front passenger seat frame could rub against and damage the passenger presence sensor (PPS) module wiring, causing the system to improperly suppress the front passenger airbag. Drivers should be alerted of a problem in three different ways.

• The service airbag message will be displayed in the DIC.
• The airbag telltale light may be illuminated.
• The indicator will show that the passenger airbag is off even if a passenger is in the front passenger seat.

Those receiving notices will be asked to return to their dealerships to have the wire harness wrapped with anti-abrasion tape. Damaged wires will be replaced as necessary. For more information about the problem, owners are asked to contact Chevrolet customer service at 1-800-521-7300. GM’s recall campaign number is 36110 and the NHTSA campaign number is 16V-507.
