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.

Chattering when cornering can occur when the limited slip differential fluid breaks down. Replacing the fluid will repair this issue.

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.

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

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.

Lack of oil changes can cause the piston rings to become clogged with debris resulting in excess oil consumption. Severe engine damage may result if the oil level gets to low. Engine dis-assembly may be required to clean or replace the piston rings. Our technicians recommend proper maintenance to try and avoid this expensive repair.

The fuel level sensor may fail resulting in erratic reading of the fuel gauge. Sensor replacement is generally required to 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.

 

The check transmission light may illuminate with a stored code 37. This is commonly caused by electrical interference on the data communication circuit between the transmission control module (TCM) and the engine control module (ECM). Our technicians recommend that all related connection and ground locations should be inspected and repaired as necessary. In some cases electromagnetic interference may be the cause, shielding of the affected wiring may be of help it this case.

The transmission may develop a harsh shift condition with the Check Engine Light on and fault code P0717 stored. This is commonly cased by a failed input speed sensor (ISS), located inside the transmission. The wiring at the sensor may be found damaged. If so, the sharp edges near with ISS wiring should be filed smooth to protect the new speed sensor wiring from damage.

The Anti-lock brake system (ABS) control unit may fail internally causing the ABS warning light to illuminate.

Some engines may develop an oil leak at the front of the engine, the source is commonly the front crankshaft oil seal. Our technicians tell us a revised front oil seal retainer gasket is available to correct this concern.

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