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.
Accessory belt:
The A/C belt may squeal or break because the compressor (and its pulley) goes out of alignment. (2003)
Automatic transmission:
The automatic transmission may engage slowly, shift hard or into the wrong gear requiring reprogramming of the transmission control module. (2003)
Brake noise:
On vehicles not equipped with Brembo calipers, the brakes are noisy, particularly in reverse, requiring replacement of all shims and revised brake pads. (2003-04)
Cold-starting problems:
In very cold conditions, the starter may not run and may require replacement of the Intelligent Power Distribution Module. (2004)
Radiator:
The radiator cap gasket may swell over time and when it does, will not allow the cap to vent properly resulting in overheating and lost coolant. (2003-04)
