Known Problems
Some vehicles may exhibit a "buzz", whining", or "moaning" like noise from the transmission when reverse gear is selected. The condition is caused by a resonance of the transmission regulator valve system. Our technicians tell us that the repair involves replacing the transmission regulator (aluminum) valve with a steel one.

The instrument cluster may work erratically at times. Our technicians tell us that the fault is commonly due to connection issues at the cluster electrical connector. There is a kit available to repair the connector and terminals.

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.

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

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

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.

Problems may develop with the sliding door. Our technicians tell us that there is a revised latch assembly are latch rods available to correct sliding door latch issues.
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.
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.

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.
