Additional 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)

Throttle Body: The throttle body control valve tends to sludge up on the 1.8L turbo engine causing a very low or uneven idle. (2002)
