Known Problems

The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

The high pressure power steering hose will commonly leak fluid; it should be replaced.

The automatic transmission shifter may fail, or a wire may break near the shifter causing the ignition key to become stuck in the ignition lock cylinder.

The mass air flow or crankshaft position sensor may fail causing the engine to intermittently stall. It may be necessary for the engine to cool down before it will restart.

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 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 water pump may develop a coolant leak resulting in an engine overheating condition.

A Loose or worn gas cap may cause Check Engine Light to illuminate.

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.
