Known Problems
Dodge issued a recall for fuel leaks. Dealers will reinforce the fuel rail to prevent cracking and replace the O-ring seals on the fuel rail and fuel injectors.

Worn sway bar bushings or sway bar end links may cause a rattling or clunking noise from the front suspension during low-speed driving. Though not always the root cause, front struts are often replaced for this condition.

The window glass lift plates tend to bend or break and cause the window glass to tilt and bind in the door. The lift plates can be replaced separately from the window regulator. In more severe cases, however, a new window regulator may also require replacement.

Debris and corrosion in the AC housing may cause the AC evaporator core to develop a refrigerant leak.

A defective fuel pump check valve (which maintains fuel pressure in the system when the vehicle is not running) may lead to long cranking times or hard starting (sometimes with stalling). The fuel pump should be replaced. However, if these symptoms are accompanied by Check Engine Light illumination, there may be a problem with the engine coolant temperature (ECT) sensor.

The fuel level sensors can wear out and cause erratic or inaccurate fuel gauge readings.

Poor output from the heater and/or engine overheating can be caused by air left in the cooling system after the cooling system has been serviced. Our technicians tell us the proper coolant fill procedure should be used to prevent this problem from occurring.

When the car is accelerating, spark plug cables may cause intermittent misfires and popping sounds from the engine compartment.

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.

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

When shifting from Drive to Reverse (or vice versa), worn outer CV joints may cause a clunk or clicking noise. A loose axle nut can cause the same symptoms.

The automatic transmission can develop problems like harsh shifting, shuddering between shifts, and a buzzing while in Reverse. Repairs for many of these problems are outlined in service bulletins and require removal and disassembly of the transmission.

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.

A dirty throttle body may cause low engine idle speed or frequent stalling, as oily residue blocks air flow in the throttle when the throttle is closed. Throttle body cleaning may be necessary to correct this condition. Our technicians caution against spraying cleaner directly onto the throttle body as this may damage the throttle position sensor (TPS).

When a no start condition is caused by a faulty camshaft or crankshaft sensor, related fault codes stored in the powertrain control module (PCM) should not be trusted. Our technicians tell us that under certain conditions a fault code can be stored for the "good" sensor. Care should be taken to properly diagnose this condition.
