Vehicles equipped with the multiple displacement system (MDS) must use the correct 5W-20 oil in order to function properly.
If the radio station or CD track changes when the steering wheel volume control is used, a revised body control module (BCM) will fix the problem.
Water may enter the liftgate ajar switch and corrode the switch connectors. This can cause the information center to display the liftgate ajar warning, the rear wiper to be inoperative, the interior lamps to stay on, the security alarm not to set, and/or the battery to drain when the engine is off. A new liftgate ajar switch is needed and the harness connector should be repaired.
Chafed wires in the neutral position switch harness can cause an inoperative or intermittent operation of the speed (cruise) control. The harness wires need to be repaired and routed away from the throttle cable bracket on the transmission.
Due to misfires, you may experience a loss of power when accelerating between 50 and 70 MPH (most noticeable below 32° F). Due to carbon buildup on the valve stems, the exhaust valves may close too late. All of the exhaust valves should be inspected and, if necessary, the engine should be decarbonized.

Software updates are available to address erroneous illumination of the "Service 4WD System" warning light and other issues (e.g. shifting, performance).
Excessive gear noise can indicate differential bearing failures.
A short circuit in the shift interlock cable solenoid can cause various symptoms—the speedometer needle may jump or vibrate when the brakes are applied, a fuse can blow in the fuse panel, or the brake warning light may illuminate. The shift interlock cable may need to be replaced.
Mopar has a lubricant that can help with squeaking sway bar bushings.
Sway bar bushings made from a different material were released to solve a squeaking problem (usually when driving over bumpy roads).
For the first few miles driven (before the brake pads warm up), the rear brakes may squeal with light brake pressure. Updated rear brake pads are available.
