The thermostat may fail to close completely, causing the Check Engine Light to illuminate. This problem will prevent the engine from reaching normal operating temperature; a new thermostat should be installed.
A whining noise heard driving at freeway speeds (more than 55 mph) can be normal noise from the rear axle which is being transmitted through the body. A body/frame damper is available which may help with this concern.
Under certain conditions, some models may shift into neutral even though reverse is selected with the gear selector. A software update for the Powertrain Control Module (PCM) to correct this issue will allow reverse engagement as long as the transmission has sufficient hydraulic pressure.
While in automatic temperature control, if the air temperature from the vents does not change after selecting a cooler temperature, a possible cause is a failed infrared temperature sensor.
If the moon roof makes a thumping noise moving from the closed to the vent position, using some lubricant (available from Dodge) on the moon roof seal may solve the problem.
