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.
Due to a potential problem with seatbelt pretensioners, front seat occupants may not be properly restrained in the event of a crash, increasing the risk of personal injury. Dealers will replace both front the driver's and the passenger's lap belt pretensioners to correct this concern. Remedy parts are not currently available, owners will be sent a notification when parts become available.
The driver's and/or passenger's seat may suddenly drop to its lowest position because a bolt securing the height adjuster can fall out. This unexpected movement of the driver's seat could cause a distraction, increasing the risk of a crash. Dealers will replace the height adjuster bolts in both front seats to correct this concern.
Due to an incomplete weld on the seat hook bracket assembly, the front seats in the affected vehicles may not stay secured in place. A seat that does not stay secured increases the risk of occupant injury in a vehicle crash. Dealers will inspect the lower seat track and replace it as necessary to correct this concern.
In cold temperatures, the insulation on the engine block heater cord can become damaged, allowing the wires to be exposed. Exposed wires increase the risk of electrical shock and personal injury if the cord is handled while it is plugged in. Dealers will replace the block heater cord to correct this concern. The new cord is rated for temperatures of -40C.
Excess weight on the key ring can cause the ignition switch to move out of the run position without warning, turning off the engine. This defect can also affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. Dealers will install two 13mm key rings and key insert into the vehicle's ignition keys to correct this concern.
In the affected vehicles, there is a flexible steel steel cable that connects the seatbelt buckle to the front seat frame. Over time the cable may fatigue and separate. If the steel cable separates, the seatbelt may not properly restrain the seat occupant, increasing the risk of an injury in a crash. Dealers will inspect and replace the affected seatbelt buckles (lap pretensioners) to correct this concern.
Certain vehicles equipped with 17 inch front brake rotors are being recalled because during vehicle assembly, brake rotors intended for the rear may have been installed on the front. The rear rotors, while the same diameter, are thinner and may result in a front brake pad detaching from the caliper. Braking ability would be reduced suddenly if a brake pad were to detach. The resulting increased stopping distance would increase the risk of a crash. Dealers will inspect the front brake rotors, and install the correct rotors with new brake pads, as necessary to correct this concern.
Increased resistance in the front seat mounted side impact air bag (SIAB) wiring harness can result in the SIAB and seat belt pretensioners not deploying as expected in the event of a crash, increasing the risk of personal injury. Dealers will replace the affected harness connections with soldered connections to correct this concern.
Fluid may enter the driver's door module, causing corrosion that could result in a short circuit in the door module. A short circuit 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. Dealers will inspect the driver's door module, if it is functioning correctly, a protective coating will be applied. If the module is not functioning correctly, it will be replaced. The GM recall number is 12180.
