The automatic transmission shifter may fail, or a wire may break near the shifter causing the ignition key to become stuck in the ignition lock cylinder.

Engine Oil Leaks Onto Exhaust Manifold

Engine oil can leak onto the exhaust manifold, causing a fire hazard. This concern was addressed in previous recall notifications, but improvements to the repair have been made. Dealers will make improved repairs free of charge to resolve the concern.

Front Passenger Air Bag Stays Active With Child Seat Installed

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 Leaks

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.
