Buick is recalling approximately 4,077 2012 Buick LaCrosse sedans due to issues with the Electronic Stability Control (ESC). The affected vehicles were manufactured from June 9, 2011, through July 2, 2011.
The problem is with Stabilitrak, Buick’s electronic stability control system. An incorrect calibration may result in the system not detecting whether a sensor had malfunctioned. If this were to occur, the warning light indicating that the system is not operating would not illuminate. This fails to meet the requirements of Federal Motor Vehicle Safety Standards regarding stability control systems.
The malfunction could prove to be very dangerous, causing the stability control to falsely activate, resulting in a possible accident due to sudden changes in handling that could cause you to lose control of your vehicle.
GM dealers will resolve the issue by reprogramming the vehicle’s electronic brake control module—one component of the complex stability system—free of charge. The recall is expected to begin this month.
If you own one of the affected vehicles, GM’s safety recall number is 11222. Owners can also contact Buick at 866-608-8080, or the National Highway Traffic Safety Administration’s (NHTSA) vehicle safety hotline at 888-327-4236, and reference recall number 11V404000.
