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 system may quit working intermittently due to failure of the low pressure switch on the compressor. (2003)
Battery:
The battery may go dead because the ignition switch may not be in the fully off position, even with the key removed requiring replacement of the ignition switch. (2003-05)
Clutch:
A rumbling noise at just below 55 mph is caused by the normal full lockup of the torque converter clutch; and the vibration is transmitted to the passenger compartment by the rear springs which must be replaced. (2003-05)
Electrical problem:
The instrument panel may quit working and the transmission may default to second or third gear due to no voltage to the transmission solenoid. (2003-06)
Electrical problem:
Transmission may upshift too quickly and even engage the lockup converter below 20 mph due to an electrical short that tricks the powertrain control module into believing the transfer case is shifted into four-wheel low range. (2003-04)
Vehicle noise:
Various noises from the front end due to prematurely worn stabilizer links. (2003-04)
Water leak:
Water on the front floor may be due to one or more leaks at the A-pillar near the windshield. (2003-05)
