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.
Brake noise:
The front brakes may chatter or oscillate and make a groaning sound in low-speed turns requiring the rotors to be machined and revised brake pads installed. (2003-04)
Climate control:
The heating and ventilation system may not go into recirculation mode due to electrical problem in the climate control unit. (2003-06)
Engine misfire:
