ELECTRICAL SYSTEM

The defect

General Motors LLC (GM) is recalling certain model year 2014 Buick LaCrosse vehicles manufactured April 30, 2013, to September 1, 2013. In the affected vehicles, a wiring splice in the driver's door may corrode and break, resulting in the absence of an audible chime to notify the driver if the door is opened while the key is in the ignition. Additionally, the Retained Accessory Power (RAP) module may stay active for ten minutes allowing the operation of the passenger windows, rear windows, and sunroof. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 114, "Theft Protection and Rollaway Prevention," and 118, "Power-Operated Window, Partition, and Roof Panel Systems."

The risk

Without an audible indicator, the driver may not be aware that the driver's door is open while the key is in the ignition, increasing the risk of a vehicle rollaway. If the passenger windows, rear windows, and sunroof can function when the vehicle is turned off and the driver is not in the vehicle, there is an increased risk of injury if an unsupervised occupant operates the power closures.

The fix

GM will notify owners and dealers will inspect the driver door window motor harness, and replace the electrical splice, as necessary, free of charge. The recall began August 2014. Owners may contact Buick customer service at 1-800-521-7300. General Motors number for this recall is 14235.
