The anti-theft system may cause a no start condition due to electrostatic discharge (ESD) affecting the wireless control module (WCM). There is an updated WCM to correct this issue.
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.
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.
There have been reports of premature head gasket failure; an updated gasket design is available to correct this problem.
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.
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 damaged oil pump (possibly caused by interference with the AC compressor bracket) can also cause a knocking noise from the engine compartment; a modified bracket is available from Dodge.
Failure to use the correct automatic transmission fluid and follow the maintenance schedule can result in shifting problems.
A defective EGR valve can cause a popping or knocking noise from the engine compartment. It is usually heard when the engine is warm (between 1600 and 1800 RPM).
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.
The alarm may activate randomly when the doors, trunk, and hood are all closed. This may happen in windy conditions. Improper height adjustment of the hood can contribute to the problem. The repair involves adding a foam pad to the alarm switch area.
Clogged drains can cause many problems with the sun roof. To prevent water damage related problems, the sun roof and its drains should be clear of leaves and dirt. The sun roof may also stick or bind for other reasons. There are service bulletins that address many of these concerns.
The plastic trim on the power seats can cause the seat switch to stick; new trim is available.
