Buick Recall 11222: Electronic Stability Control System FMVSS 126
2012 Buick LaCrosse
The improper diagnosing may cause the ESC to falsely activate, resulting in sudden changes in vehicle handling and deceleration, particularly at higher speeds, which may cause the driver difficulty in maintaining the vehicle's desired path of travel and desired vehicle speed, and could result in a crash without warning.
GM is recalling certain model year 2012 Buick Lacrosse passenger vehicles manufactured from June 9, 2011, through July 2, 2011, for failing to conform to the requirements of Federal Motor Vehicle Safety Standard no. 126, "electronic stability control systems (ESC)." The stabilitrak system has an incorrect calibration that may cause the system to not properly detect if a sensor were to malfunction, and the warning light indicating that the system is not operating would not illuminate, as required in the safety standard.
