Report A Problem

As described in the title, my Pac (fwd) developed a low pitched noise seemingly related to minor road undulations, noticeable especially after driving the car for a few miles, and more noticeable when the air temp was above 80 degrees F. The driver side rear of the car was measured at the wheel well to be sitting about 3/4" lower than the passenger side. I suspected a shock, but giving it the static "bounce test" did not seem to be overly bad...

Carbon buildup on the valves may illuminate the Check Engine Light, indicating "Multiple Cylinder Misfires." The combustion chamber must be cleaned of carbon. There are updated valve spring retainers that will help prevent a recurrence.

"False" trouble codes may cause erroneous illumination of the Check Engine Light. Updating the PCM software can often correct this concern.

If the HVAC (heater) housing is not properly sealed at the bulkhead (firewall), water can leak into the passenger compartment. Foam sealant should be used to seal any gaps and the evaporator drain tube can be modified to prevent further water entry.

Static discharge and/or loose wire connections could cause problems with the front power seat memory, seat heaters, and adjustable pedals. Revised seat modules are available that resist the affects of static discharge.

The engine may develop a ticking noise, often caused by a broken retaining pin on the rocker arm shaft. When the pin breaks, the shaft can spin blocking the oil passage the rocker arms (which causes the ticking noise). The rocker arm shafts, rocker arms, and pedestals (sold as a kit) are commonly replaced in order to correct this condition.

Misalignment of the drive belt pulleys can cause a chirping or squeaking noise from the drive belt.

Static discharge through the right (passenger) front door handle can result in a loss of functionality from the right front door switches, power mirrors, seat controls, and door locks. There is a revised door handle which is more static resistant. A new door module may be needed if the module does not reset properly.

A problem with a solenoid valve in the transmission may cause the Check Engine (MIL) light to come on.

If the engine is hard to start or if it cranks but does not start in freezing temperatures, a new idle air control (IAC) motor and software update to the Powertrain Control Module (PCM) may be needed.
If the cup holder lid will not stay closed, a lid spring was released so replacing the entire assembly should not be necessary.
If the moon roof makes a thumping noise moving from the closed to the vent position, using some lubricant (available from Dodge) on the moon roof seal can solve the problem.
