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.
Air conditioner:
The A/C may not cool enough or may fluctuate, requiring replacement of the A/C amplifier. (2004)
Cold-starting problems:
Engine cranks but doesn't start when cold or after running a very short time, as when moving location a short distance, due to flooding. There was a recall to recalibrate the PCM, plus revised leading spark plugs may need to be installed and the catalytic converter may have to be replaced if damaged. (2004)
Dashboard lights:
The low oil level warning may come on, but the level may check out OK on some early production vehicles, requiring replacement of the oil pan and level sensor. (2004)
Engine stalling:
The engine may stall and set a variety of trouble codes and is fixed by reprogramming the PCM.
None:
The dipstick may have a milky substance on it, which is normal after cold soak, but there is a dipstick tube sleeve available to prevent this. (2004-05
Seat:
The driver's seat may lose its memory function, requiring replacement of the control unit under the seat. (2004-05)
