Known Problems

The automatic transmission accumulator cover can leak due to a failed o-ring. Replacing the o-ring and cover will commonly correct this issue.

On some models the powertrain control module (PCM) software delays idle speed changes during cold starts causing stalling problems. A software update is available to repair this issue.

The fuel level sensor may fail resulting in erratic fuel gauge operation and illumination of the Check Engine Light. Replacement of the fuel sender assembly is recommended to correct this concern. A powertrain control module (PCM) software update may be necessary for the updated fuel level sensor to read correctly.

A worn vehicle speed sensor driven gear can cause the speedometer not to work. Replacing the worn out speed sensor should correct this concern.

The anti-lock brake system (ABS) warning light may illuminate due to a damaged wire harness near one or both of the front wheel speed sensors. Repairing the damaged wiring will be necessary to correct this concern.

 

On some models the rear wire harness for the Anti-lock brake system (ABS) can fatigue and break causing the ABS light to come on. Replacing the harness with a new updated harness should repair this problem.

Certain models may have a vibration issue at highway speeds that could be due to uneven tire pressures, tire rim out of specs, wheels out of balance, AC compressor bracket bolts not torqued correctly, misalignment of the steering shaft coupler, improper ride height, or wheel alignment out of adjustment. A qualified technician is needed to sort out these problems and correct them.

On the V-6 engine, oil in the spark plug tubes can cause a misfire. Resealing the tubes as part of replacement of the valve cover gasket and replacing the spark plug wires will commonly repair this issue. On newer models the misfire can result in illumination of the Check Engine Light.

A ticking noise may be noted from the engine valve train area. This is commonly caused by varnish build up in the hydraulic lash adjusters (HLA). Our technicians tell us that using Mobil 1 synthetic oil has been successful in cleaning the varnish deposits and quieting the lifter noise.

On certain models the door checks can contact  the door wiring harness and damage the wires causing blown fusees and no sound from the door speakers. Repairing the wires or replacing the harness and routing it away from the door checkers will repair this issue.

Certain models can get a brake squeal at the end of a stop due to the front brake pads leaving a film on the brake rotors. Replacing the brake pads and turning the rotors will fix this issue.

On certain models contamination of the grease on the gas pedal potentiometer causes the Check Engine light (MIL) to come on and may cause a rough idle. The potentiometer will need to be replaced and adjusted to fix this problem.

A leaking fuel pump o-ring can cause the Check Engine light (MIL) to come on. Replacing the faulty o-ring will correct this.
