Known Problems

With the Mulit-Displacement System (MDS), repeated Check Engine (MIL) light illumination for low oil pressure may be solved with a software update to the Powertrain Control Module (PCM).

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.

The transfer case in the Chrysler Aspen has multiple gear ratios, which can be selected by moving the switch in the cabin to 2Hi, 4Hi, or 4Lo. It has been known to shift to 4Lo without warning, at any speed, and whether the vehicle is on or off. If this occurs at highway speeds, the result can be catastrophic failure of the transfer case.

This is caused by a faulty four wheel drive shift motor, selector switch (in the cab) or the wiring between the two. The most common cause is the transfer case switch, which is an electric motor mounted on the transfer case. 

To correct the issue, inspect the wiring to the transfer case switch motor for damage, and replace the shift motor if needed. Disconnecting power to the shift motor will lock the transfer case in its current setting.  

A weak or dead battery may be caused by power draw from the radio. If the radio display flickers with the key removed and the doors closed, radio replacement will be needed.

Exhaust manifold bolts commonly break, exhaust manifold gaskets should be replaced and replace bolts as needed.

Some vehicles may develop a musty odor coming from the HVAC system, Dodge has issued a cleaner/disinfectant and a coating for the evaporator designed to inhibit bacterial growth.

The Check Engine Light may illuminate for many different reasons, some of which may be corrected by updating the software in the powertrain control module (PCM).

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.

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.

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.
