When driving, if you let your foot off the accelerator, the engine will provide some braking effect unless your transmission is in "Sport" mode. Certain vehicles are being recalled because the transmission may unexpectedly shift into its "Sport" mode, removing the engine braking effect on these vehicles. Unexpected loss of engine braking can increase stopping distance, increasing the risk of a crash. Dealers will update the software in the transmission control module to correct this concern.
The driver's front airbag includes a safety device called a shorting bar - this prevents unexpected deployment of the airbag when it is removed from the vehicle. In this case, the shorting bar may intermittently contact the airbag terminals while it is installed in the vehicle. This could result in illumination of the airbag warning light or the airbag may not deploy when necessary. Failure of the airbag to deploy would increase the risk of injury in the event of a crash. Dealers will replace the steering wheel airbag coil to correct this concern.
The driver side frontal air bag has a shorting bar which may intermittently contact the air bag terminals. If the bar and terminals are contacting each other at the time of a crash necessitating deployment of the driver's frontal airbag, that airbag will not deploy, increasing the driver's risk of injury. General Motors dealers will replace the steering wheel airbag coil to correct this concern. The General Motors recall number is 12261
The front turn signals are equipped with two bulbs on each side. If one bulb fails, the driver would not be made aware of the loss of light function, which could create a safety hazard. Dealers will update the body control module software free of charge to resolve the concern.
Vehicles first sold, or currently registered, in certain states where salt is used to de-ice the roads are being recalled because fluid may enter the driver's door module, causing corrosion that could result in a short in the circuit board. A short may cause the power door lock and power window switches to function intermittently or become inoperative. The short may also cause overheating, which could melt components of the door module, producing an odor, smoke, or a fire. As of this time, the remedy plan is still being finalized and a notification schedule has not been determined. The GM recall number is 12180.
Snow or ice buildup on the windshield or on the wiper restricts the movement of the wiper arm. The wiper arm may loosen and cause the wiper to become inoperative. If this occurs, driver visibility could be reduced, increasing the risk of a crash. Dealers will tighten the wiper arm nuts to correct this concern. The General Motors recall number is 12036.
Due to a software error, the parking lights do not activate when either the parking lamps or headlamps are switched on. Inadequate lighting could reduce visibility, increasing the risk of a crash. Dealers will reprogram the body control module to correct this concern. The General Motors recall number is 12048.
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.
The HVAC system may stop functioning due to a software issue in the climate control module. System failure would reduce the driver's ability to command the defrost function. This can reduce visibility, increasing the risk of a crash. To correct the problem, dealers will reprogram the electronic control module for the HVAC. The recall is expected to begin by March 11, 2011. The General Motors recall number is 11057.
General Motors is recalling 2010–2011 DTS and Buick Lucerne models with V8 engines due to contact between the starter/alternator cable and the power steering return line. This can result in a worn power steering return line, which can cause a power steering leak, possibly resulting in a loss of power steering. This can lead to an increase in the risk of a crash and/or an engine compartment fire. Dealers will secure or reroute the necessary lines, free of charge.
