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.
Coolant leak:
The expansion plug on the right-side intake manifold may leak coolant requiring installation of a revised manifold. (1999)
Fuel odors:
A rotten-egg odor from the exhaust may require reprogramming of the engine-control module. (2000)
Poor transmission shift:
The key may be difficult to remove and/or the shifter may be hard to move from park due to a bent spring in the shift-lever mechanism. (1999)
Poor transmission shift:
Unless the transmission cooler is thoroughly cleaned following a transmission repair, the newly serviced unit will likely soon fail. (1999-2002)
Power seats:
The power seat may not move fore and aft because the drive cable breaks. (1999-2001)
Starter:
Starter may grind, particularly when cold, due to loss of lubrication. Replacement starters have high-temperature grease. (1999-2000)
Vehicle noise:
A clunk from the rear of the car when driving over speed bumps or curb cuts (when the back seat and trunk are empty) is fixed by installing revised springs and shock absorbers. (1998-2000)
Windows:
Windows may stick and make a popping noise if not used for more than a day due to problems with the rubber window guides that must be replaced. (1999)
