The passenger front air bag may not deactivate as designed due to a failure of the sensing system. Dealers will correct the calibration-learning error by preconditioning the empty seat and also resetting the control unit to a seat zero-value free of charge to resolve the concern.
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.
The rear brake pads may stay partially applied after the parking brake is released. The electronic parking brake actuating piston may not fully retract. Dealers will reprogram the electronic parking brake control module with new software free of charge to resolve the concern.
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.
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 parking brake actuation arm may stay partially engaged when the parking brake is deactivated. This can cause the brake pads to stay partially applied and overheat, resulting in a fire hazard. Dealers will update the electronic parking brake software free of charge to resolve the concern.
The module that controls the functionality and operation of the air bags may have been set to "manufacturing mode" when leaving the factory. This would prevent normal air bag deployment from occurring in a crash. Dealers will reprogram the sensing and diagnostic module (SDM) free of charge to resolve this concern.
The center storage console may not stay latched in the event of a collision. Dealers will replace the console storage compartment door inertia latch free of charge to resolve the concern.
The power steering system may fail due to a faulty electrical ground to the power steering control module (PSCM). Dealers will clean paint from behind the ground stud nut and update the PSCM software free of charge to correct the problem.
