RepairPal Expert Overview
The anti-skid (stabilitrak) system warning light may not illuminate in the case of certain system sensor faults. A faulty sensor could cause unexpected changes in vehicle handling, which could result in a crash.
General Motors will notify owners of affected vehicles during August of 2011. If you are experiencing handling issues and don't receive notification, please contact your dealer. It's helpful to have your vehicle identification number (VIN) when you call.
The anti-skid (stabilitrak) system may have an incorrect calibration, which can cause the system not to properly detect a sensor malfunction. A malfunctioning sensor may cause the stabilitrak (ESC) to falsely activate, resulting in sudden changes in vehicle handling and deceleration. These unexpected changes in vehicle handling may cause a loss of vehicle control. Dealers will update the electronic brake control module (EBCM) software to correct this concern. The General Motors recall number is 11222.
