Known Problems

An intermittent connection in the crank position sensor wire connector can cause poor engine performance or the engine may crank but not start.

Intermittent erratic oil pressure readings may be caused by a PCM software issue. There is revised software available to correct this condition.

Our technicians tell us that there is a software upgrade for the ABS module to correct inaccurate speedometer readings.
A knocking noise front the front suspension may be caused by interference between the idler arm and the stabilizer bar. Our technicians tell us that if this is the case a revised stabilizer bar is available.
Our technicians tell us that some transmissions may exhibit harsh shift conditions or a false PCM codes P1763 and may benefit from a PCM software upgrade.
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.
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.

Battery acid may leak onto an ABS wiring connector which could cause corrosion or a short circuit. A revised battery tray is available to protect the wire harness. Any damaged wiring will need to be repaired as necessary.

Insufficient fuel pressure may be caused by particulate contaminates or other type of substances by-passing the primary fuel pick-up screen and resulting in fuel pump failure. Our technicians recommended to replace entire fuel pump module assembly as two (2) filters, primary and secondary are included with the assembly.

An erratic idle, stall on hot restart and/or low speed deceleration. may be caused by a faulty idle air control motor. Our technicians tell us there is a revised IAC motor to correct this condition.

The engine may exhibit excessively high oil pressure at cold start up. This may lead to distortion of the oil filter case. Inspect the oil filter case for any signs of distortion. If the case is distorted,  Connect an oil pressure gauge to the engine and start the engine while observing the readings. If the pressure reads above 80 psi, replace the oil pump.

Excess cooling fan noise may be caused buy a faulty cooling fan and fan clutch.

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.

The blower motor may operate erratically and the blower switch operation has a sticky or mushy feeling, the detents almost non existent. Our technicians tell us that the blower switch should be removed and inspected for overheating. This is common if the blower motor is frequently operated on high speed as the current flow through the switch tends to melt internal the components. Also carefully inspect all of the switch connector terminals for discoloration due to overheating and replace as required. A poor electrical contact at the connector will also cause the switch to overheat.

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.
