Known Problems

A dirty throttle body may cause a lower than normal idle and an engine stalling condition can develop. Performing a throttle body service will generally correct this concern.

The AC system may not blow cold at times. In many cases, replacement of the AC compressor has corrected this issue.

The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault. The warranty has been extended on some of these units to 7 years or 70,000 miles.

Corrosion at the fuel tank to body harness may cause the Check Engine Light to illuminate or a crank no start condition. This corrosion issue is most commonly caused by a water leak inside the vehicle. Any damaged wiring or connectors will require replacement.

The turn signal switch in the steering column may fail causing the turn signals not to work on one or both sides.

The inside door handles are prone to breaking.

The upper intake manifold gasket and/or a PCV vacuum lines/hoses can develop vacuum leaks with age. This type of leak can result in a higher that normal or rough idle.

You may be able to prevent transmission problems by servicing the transmission and inspecting the fluid every 30,000 miles. If the fluid is dark or burned then the transmission system should be completely flushed.

Flex fuel vehicles can develop fuel calibration issues resulting in illumination of the Check Engine Light and/or lack of power. This commonly occurs if only short trips are taken after changing fuel type from E85 to gasoline or gasoline to E85. In most cases, the fuel calibrations can be reset for gasoline using a properly equipped scan tool.

The anti-lock brake system (ABS) front wheel speed sensors are prone to failure. When a sensor fails, the ABS warning light may illuminate and/or the ABS system may activate erratically.

The fuel gauge may not read correctly and/or the Check Engine Light may illuminate with code P0455/P0461 stored for a fuel level sensor issue. These faults may be caused by a fuel vapor line inside the fuel take interfering with the fuel level sensor. If this is found to be the case, repositioned and securing the vapor line should correct this concern. If no fault is found with the fuel vapor line, the fuel level sensor itself may be at fault.

The engine may develop a misfire due to worn valve seats. This fault will cause the Check Engine Light to illuminate. Replacement of the cylinder head may be required to correct this concern.

The front or rear differential may develop an abnormal noise due to worn bearings or another internal fault. Our technicians tell us that a complete overhaul of the affected differential is commonly necessary to correct this condition.

The fuel pump may fail causing engine to stall and not restart.

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.
