The roof rail air bags may deploy unexpectedly due to excessive vibration from the vehicle's drive shaft. Dealers will replace the rear drive shaft assembly free of charge to resolve the concern.
Due to a failure of the transmission shift cable brackets, the shifter indicator may read the wrong gear as selected. If "park" is selected, but not actually engaged, the vehicle may move unexpectedly. Dealers will inspect for proper shift cable mounting and ensure proper routing free of charge to resolve the concern.
The windshield wipers may fail in certain conditions, such as turning the vehicle off while leaving them turned on, followed by being covered by ice and snow. Dealers will replace the front wiper module free of charge to resolve the concern.
There may be a three to four second delay and lag in vehicle acceleration when commanded. Dealers will reprogram the transmission control module free of charge to resolve the problem.
The electronic stability control system malfunction indicator light may not come on when a failure of the system occurs. This is because of a software problem. Dealers will update and re-calibrate the system module free of charge to resolve the concern.
Corrosion may develop at the brake booster pump connector at the pump relay due to a missing cavity plug. This corrosion can cause excessive heat, resulting in the connector melting and possibly catching on fire. Dealers will apply sealant to the affected connector cavity plugs and re-route the vacuum pump vent hose. If damaged, the front body wiring harness will be replaced as necessary.
Certain vehicles are being recalled because of concerns with the brake lights and cruise control operation. The brake lights can come on when the brakes are not applied and/or the cruise control may disengage. These functions are controlled by the Body Control Module (BCM). Your GM dealer will reprogram the BCM to correct this concern.
Lug nuts tighten on the wheel studs to secure the wheels to the vehicle. These vehicles are being recalled because the lug nuts can loosen and fall off, or cause the wheel studs to break. A vibration would commonly occur as the wheel lugs loosen and continued driving with loose or missing lug nuts would result in the affected wheel falling off, increasing the risk of a crash. To correct this concern, dealers will remove and re-install the lug nuts, and perform a tire rotation free of charge.
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.
All late model vehicles are equipped with a "Shift interlock" system that prevents vehicles with and automatic transmission from being shifted out of the Park position under certain conditions. Some of these vehicles are being recalled because they may have been assembled with a broken park lock cable or a malformed steering column lock actuator gear. Failure of these components can allow the shifter to be moved out of the Park position with the ignition key removed or in the off position. This can cause the vehicle to roll away unexpectedly increasing the risk of injury or a crash. Dealers will inspect the recalled vehicles and replace the steering column as necessary.
