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.
Brakes:
The ABS (anti-lock brakes) may activate unnecessarily under normal to light application due to cracks in tone wheels. (1996-05)
Coolant leak:
The oil cooler is prone to turning during oil filter removal, which causes damage to the coolant lines resulting in a coolant leak. (2002)
Electrical problem:
Water leaks into wiring harness near the A-pillar causing assorted problems such as the remote will not lock/unlock the door, the windows won't work, the interior lights may stay on occasionally, and the door ajar warning may glow even though the doors are shut. (2002)
Hard starting:
Engine may crank, but not start. The cause may be carbon buildup in combustion chambers and/or valves requiring extensive cleaning. (1998-99)
None:
The throttle body control valve tends to sludge up on the 1.8L turbo engine causing a very low or uneven idle. (2002)
