Known Problems

The automatic transmission can develop problems like erratic shifting, rough shifting, or delayed gear engagement. Repairs for many of these problems are outlined in service bulletins.

An engine Oil leak may develop at the cam sensor o-ring seal. Our technicians tell us this is often misdiagnosed as an external head gasket leak.

A defective vehicle speed sensor can cause problems with the cruise control and speedometer operation, as well as erratic shifting. The connectors on the sensors are also susceptible to corrosion, which will create similar symptoms. Any of these problems can cause Check Engine Light illumination.

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.

Sensor failure inside the distributor can cause intermittent stalling or a failure to start. In addition, the wires to the distributor are susceptible to internal damage, which can cause the same symptoms.

Spark plug tube seals fail, causing the tubes to fill with engine oil and the engine to misfire. As a result, the engine may run poorly and fuel economy can suffer.

Warm air only may be discharged from the AC system due to a faulty infrared temperature sensor.

A rattle from the rear of the vehicle may indicate that the rear shock absorbers are defective. Updated shocks are available; however, careful inspection of all suspension components should be performed before any parts are replaced.

There have been reports of premature head gasket failure; an updated gasket design is available to correct this problem.

Failure to use the correct automatic transmission fluid and follow the maintenance schedule can result in shifting problems.

Software updates are available to address transmission issues. However, due to the age of these vehicles, mechanical failures are more likely to be causing transmission problems. If a mechanical failure is repaired or the transmission is replaced, it is important to make sure any software updates have been taken care of. Failure to do so could result in continuing transmission issues.

Corrosion on the door ajar switch can cause the door ajar warning light and dome light to work intermittently or not at all. A new switch (and possibly a new connector) will be needed to fix the issue.
External body trim may become loose and prevent the doors from opening properly.
