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.

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.

Before refilling the coolant, make sure the air bleed valve is open. Follow the proper fill procedure—it will prevent problems with overheating, low heat output from the heater, and possible coolant bottle failure.

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).

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.

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.

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

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.

A worn AC belt idler pulley may cause the AC belt to roll over in the pulleys or come off completely.

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

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.

Be sure to follow the maintenance schedule for the timing belt. Our technicians recommend to always replace the timing belt tensioner at the same time as the timing belt.

3.5L V6
A problem with the PCV system may cause excessive oil consumption or the vehicle to emit blue smoke (burning oil) at high engine speeds (RPM). Too much vacuum allows oil to be drawn into the intake.

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.

On higher-mileage vehicles, engine oil leaks from the valve covers and front crankshaft seal are common.
