Trouble Spots
Consumer Guide's® Auto Editors have scoured repair bulletins and questioned mechanics to search for commonly occurring problems for a particular vehicle. In some cases we also give possible manufacturer-suggested solutions. In many instances these trouble spots are Technical Service Bulletins posted by the manufacturer, however, we have our own expert looking at additional vehicle problems.
Automatic transmission: The transmission may quit working due to fluid loss caused by the output flange nut coming loose. (2003-04)
Battery: The battery may go dead overnight if the brightness lever for the panel lights is set to bright and inadvertently goes far enough to power up the dash integration module, but not far enough to turn on the courtesy lights inside the car. (2003-04)
Electrical problem: The fuel gauge will read empty after filling up if the engine is left running. Trouble codes may also be set which will have to be cleared by the dealer. (2003)
Engine noise: The brackets attached to the catalytic converter may crack or break resulting in a rattle or buzzing noise that seems to come from the engine compartment. (2003-04)
Steering problems: "Service Steering SystemÓ warning light comes on because of failure of the variable effort steering solenoid. (2003)
Water leak: Passenger side carpet gets wet in winter due to ice forming in the HVAC plenum drain hose unless it is modified. (2003)
