Problem Reports

The spark plug tube seals may 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.

Defective speed sensors on the transmission can cause problems with the cruise control and speedometer operation, as well as erratic shifting. The connectors on the sensors can corrode and/or the connector terminals can spread (poor connection), 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.

If a Check Engine Light illuminates indicating leak detection pump (LDP) failure, the cause is often pinched or disconnected vacuum lines to the pump. Vacuum lines should be inspected before replacing the leak detection pump. Contamination (carbon or debris) in the pump can cause failure and any hoses should be cleared before a new pump is installed.
