When selecting the gear with the transmission shifter, the console shift indicator may not illuminate to show the gear that was selected. This could cause the selection of an inappropriate gear. The dealer will replace the transmission gear selection control module to resolve this issue.
Engine oil may leak from the valve cover area, which can cause a burning odor and increase risk of fire. Dealers will replace the spark plug wire retainer to redirect the dripping oil on affected vehicles, and will replace the left valve cover gasket on vehicles with the 3.8L V6 supercharged engine.
A switch that automatically controls the operation of the roof panel is not correctly recessed and may be activated accidentally. Any objects or passengers in the open roof area under closure could be crushed or injured as a result. Dealers will replace the surrounding switch trim to recess the switch and correct the problem.
The engine may start after exiting the vehicle, due to a software issue. The dealership will update vehicle engine management software to correct this problem.
The brackets that secure the left and right parking brake cables may become detached because of a failure of the fasteners that secure them. This can prevent the parking brake from holding the vehicle. The dealer will inspect the fasteners and tighten them as necessary free of charge to resolve the problem.
A software failure in the parking brake system has resulted in incomplete disengagement of the parking brake pads from the rotors, causing excessive brake wear and heat leading to a potential fire hazard. Increased heat in the brakes limits the ability to stop effectively, and accelerating under braking can cause damage to the transmission. Dealers will reprogram the braking module with new software to remedy the problem.
These vehicles have power steering units which may fail while driving. Loss of power steering is most noticeable while driving slowly or parking, resulting in a heavier feel at the steering wheel. Slow speed maneuvers can become difficult and potentially unsafe. Dealers will replace the affected components free of charge. This recall is an expansion of an earlier GM recall (14V-153) to cover additional vehicles.
The ignition switch actuator can bind causing the ignition switch to stick in the "start" position. If this were to occur the actuator can unexpectedly release, cause the ignition switch to snap back into the "Accessory" position. This would cause the engine to turn off with an associated loss of brake and steering power assist. If these conditions were to lead to a crash the airbags may not deploy as expected. Dealers will inspect and replace the ignition lock housing as necessary to correct this concern.
Certain trucks are being recalled because the rear axle shaft may not have been properly heat treated prior to vehicle assembly and could fail while driving. If this were to occur a rear wheel could separate from the vehicle, increasing the risk of a crash. Dealers will inspect and replace the affected axles to correct this concern.
These vehicles are being recalled because the headlamp driver module (HDM) can overheat and fail. This will cause the headlights and daytime running lights to stop working. Loss of this lighting will affect the ability of the driver to see the road and reduce the vehicle's visibility to oncoming vehicles, both of which increase the risk of a vehicle crash. The remedy for this problem is still under development and not yet available.
