Known Problems

A software issue with the sunroof module may lead to a battery drain while the ignition is off. This may cause a dead battery if the vehicle is left parked for a couple days, however reprogramming the sunroof module with new software may fix this problem.

If the engine does not crank (or cranks but won't start), the wireless control module (WCM) may have locked up. This is due to static discharge through the ignition key. A revised model should be installed, but simply disconnecting the negative terminal of the battery for thirty seconds will temporarily reset the module so you can start the car.

The sunroof cable conduit may need to be replaced if the sunroof makes a ratcheting noise as it approaches its open position.

A new lower secondary door seal is available if clothing is getting dirty when entering or exiting the truck. Dirt or mud may build up on the rocker panel below the door.

If it feels as though the steering wheel has a small amount of play (moves toward you when pulled), a new bearing retainer may be needed for the steering column.

A revised return spring is available if the cup holder binds or is slow to open.

For the 4x4 models, a high pitched whistle heard between 30 and 60 miles per hour can be caused if the tie rod adjusting sleeve is oriented in a way that the sleeve slot is facing toward the front of the vehicle. Wrapping tape completely the sleeve will allow you to verify the the sleeve is creating the whistle. Rotating the adjusting sleeve so the slot does not face forward will fix the problem.

To avoid chatter from the rear axle while turning corners, it is important to use the correct axle fluid with the correct Trac-Loc additive (if equipped).


Low oil pressure at idle or illumination of the oil pressure warning light may be caused by the oil pressure relief valve. If the oil level is good and the low pressure is verified with a gauge, the repair may involve disassembling and cleaning the relief valve.

New covers are available if the driver's side hinge cover for the center armrest breaks.

When driving over bumps a clicking or squeaking from the rear leaf springs may be fixed by replacing the (leaf) spring tip liners and installing a spring clinch clip (kit available from the dealer).

One the 3.9L V6 and 5.9L V8 the carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.

On the 3.9L V6 and 5.2L V8 it is often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.


A loud buzzing or whining when the transmission is in reverse may be caused by a regulator valve in the transmission valve body. A revised valve was released that does not resonate. Careful diagnosis should be performed because other causes can create the noise.

Battery acid can leak on, and deteriorate a vacuum hose for the speed (cruise) control system. If the hose becomes loose or leaks vacuum, the speed (cruise) control will not function.
