Known Problems

The Check Engine Light may illuminate for many different reasons, some of which may be corrected by updating the software in the powertrain control module (PCM).

One or more power windows may stop working due to a failed window motor or regulator. In some cases these items are replaced as a set. If not, diagnoses will be required to determine which is at fault.

Coolant leaks coming from the underbody on vehicles equipped with rear heat/AC are common. The underbody hoses should be inspected as part of regular maintenance. If you drive on roads where salt is prevalent the problem is generally more severe. Some 2005 models are involved in a special service action, no government recall was issued.

An oil leak from the oil filter adapter may be evident. Dodge has made a revised oil filter adapter is available.

When braking during low speeds (under 10 MPH), the brake pedal may vibrate and the ABS hydraulic unit may cause a rumbling noise. This is caused by a momentary loss of the wheel speed signal to the ABS controller. Adjusting or replacing the wheel speed sensor will commonly fix this problem.

V6 engines may experience surging while driving. The condition is more noticeable between 40 and 50 MPH while accelerating up a hill/slight incline. Replacing the powertrain control module (PCM) and updating the transmission control module (TCM) software may be required.

Misalignment of the accessory pulleys or a faulty drive belt tensioner may cause a chirping or squeaking sound while the engine is running. In If the replacing the belt tensioner does not correct the noise, the alternator pulley may require replacement.

One or more power windows may stop working due to a failed regulator or motor which will require replacement. Our technicians tell us the regulator and motor is replaced as a set on these vehicles.

Software updates are available that may help with harsh shifting issues. Software updates are commonly more effective on newer vehicles. It is possible for a mechanical failure to also cause a harsh shifting problem. Whenever mechanical transmission repairs are performed, the software should be checked and updated as necessary.

Carbon buildup on the top of the piston is common. Over time this can lead to symptoms varying from light ticking to knocking noises. Performing a fuel injector cleaning procedure can often help the condition by removing some of the piston top deposits.

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.

 

The airbag warning light may remain illuminated while the ignition switch is in the "on" position. This can be caused by water that has entered into the airbag six-way connector in the engine compartment.

The rear lift gate support (prop) attaching bolts may break, causing the lift gate to fall unexpectedly. Thorough inspection of the bolts is required; if the support washers are loose, the supports need to be replaced.

A malfunctioning switch in the steering column can cause the front windshield wipers to self-activate or not turn off. A failed windshield switch will require replacement.

A yellow anti-lock brake system (ABS) warning light may remain illuminated. If a wheel speed sensor fault is discovered, sensor connectors should be inspected. Damaged or spread terminals must be repaired or replaced.
