Known Problems

On the 3.9L V6, 5.2L V8 and 5.9L V8 the Oil leaks commonly from the valve cover gaskets, intake manifold gaskets (front and rear), timing cover gaskets, distributor O-ring, and the rear main seal area. Using fluorescent engine oil dye can be helpful in determining the source(s) of the oil leak.

Some vehicles may exhibit one or more of the following: Spark knock complaints when the vehicle is under load, various single cylinder misfire, and surge in 4th gear (around 45 mph). Our technicians tell us that rerouting the coil and spark plug wires to minimize induction effects will commonly correct this condition. If wires must cross during the reroute procedure, they must cross at a 90 degree angle.

Some automatic transmissions may set a code P1740, torque converter fault. Our technicians tell us there is a revised transmission pressure boost valve cover plate to correct this condition.

A no crank condition may be cause by a blown starter relay fuse. If the fuse is blown and the relay circuit is not shorted to ground, our technicians tell us there is a relay and harness assembly to be installed along with a new fuse.

The AC/heater (HVAC) system may unexpectedly switch to the defrost mode when accelerating. This system is operated by engine vacuum and should be inspected for any vacuum leaks if this problem develops.  There is also a revised vacuum check valve available to address this concern.

The HVAC blower may operate on high speed only. This is commonly caused by a failed blower motor resistor. Chrysler has released a revised part to address this problem.

Leak detection pump failure can be caused by the internal diaphragm switch sticking, or in some cases, contamination from debris or carbon particles from vapor canister. If black carbon particles are present in the LDP, replace vapor canister in addition to LDP. The purge solenoid should also be checked for debris or carbon contamination and replaced as necessary. All evap system hoses are subject to cracking and splitting causing leaks, Inspect hoses carefully. In cases of contamination from carbon particles or debris, all hoses and tubes must be blown out with compressed air to remove contaminates.

On the 3.9L V6 and 5.9L V8 the engine oil leaks at the distributor can be misdiagnosed as leaks from the intake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.

On 3.9L V6 and 5.9L V8 engines, the intake manifold gasket may leak and cause increased oil consumption and a spark knock during acceleration; the gasket should be replaced.


Our technicians tell us that there is a software upgrade for the ABS module to correct inaccurate speedometer readings.
The Central Timer Module may stop working intermittently causing various body systems to also stop working. There is a revised CTM available to that should correct this condition.
Intermittent cycling of the door locks especially during damp conditions may occur. Our technicians tell us that revised door and liftgate lock cylinder switches are available.
On vehicles equipped with a Theft Security system a loss of power to the Central Timer Module can result in a no start condition.
