Known Problems

Software updates are available which may correct various electrical problems with the interior features and lighting.

If you experience rough shift and/or shuddering during gear shifting, software updates to the powertrain control and transmission control modules (PCM and TCM) are available which may address these problems. On higher mileage vehicles, a mechanical failure may exhibit similar symptoms. Proper diagnoses should be performed before any repairs or software upgrades are attempted.

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.

Rear differential and axle seals are prone to repeated leaks.

One or more of the power windows may become inoperative, it is commonly caused by failure of the window motor or a cable in the window regulator. The window motor & regulator may need to be replaced as assembly.


There may be an intermittent three- to five-second delay between when you turn the key and when the engine actually cranks. If the Check Engine Light illuminates, the brake switch should be inspected and the PCM may need updated software.

A squeak may be heard from the base of the steering column while turning the steering wheel. The noise may be coming from the lower seal on the steering shaft. Lubrication of the seal will commonly correct this problem.

Water may leak into the transmission from the dipstick tube, causing fluid contamination and a shudder during light acceleration. New seals for the dipstick tube are available; the transmission fluid should be flushed as well. If the problem lingers, a new torque converter may be needed.

In cold weather, vehicles equipped with premium brakes may experience a rear brake squeal. Replacing the brake pads will not commonly fix the problem; instead, revised rear rotors are available.

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.

Often misdiagnosed as a transmission oil pan gasket leak, the electrical connector on the automatic transmission may leak.
