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 Goodyear Fortera HL tires equipped when the vehicle was built may crack, and lead to failure. Dealers will replace the affected tires free of charge to resolve the problem.
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.
A fault can develop with the Electric Power Steering resulting in sudden loss of power steering assist, increasing the risk of a crash. Dealers will replace the power steering assist motor kit to correct this concern.
The chassis electrical module can short due to internal contamination. This can result in the vehicle stalling. Dealers will replace the chassis electronic module free of charge to resolve the concern.
The hood may not be properly secured due to the hood latch corroding and being stuck out of its proper position. Dealers will replace the hood latch striker free of charge to resolve the problem.
