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 brakes make grinding, squealing, growling, and other noises, and new brake pads were issued; but new, heftier rotors are also needed. (1997-98)
Coolant leak: The 3.8-liter V6 may leak coolant into the engine from the intake manifold. A new gasket kit, revised throttle body nuts, and sealing compound is available. Redesigned manifolds are also available in the aftermarket. (1997-2004)
Coolant leak: Coolant loss via plastic intake manifold is corrected by installing upgraded manifold and gaskets plus new PCV kit. (1997-04)
Engine temperature: Overheating and coolant loss may be due to rough surface on radiator filler neck. Neck should be sanded smooth and cap replaced. (1999-2000)
Fuel odors: Fuel spurts out of the filler pipe as the tank reaches full. (1997)
Horn: The horn sounds by itself, especially in cold weather, requiring replacement of the horn pad assembly. (1997)
Keyless entry: The trunk pops open because the button on the remote is too sensitive and is easily activated while in a purse or pocket. (1997-98)
Oil consumption: The oil dipstick shows on overfilled level because the original dipstick tube is too short and must be replaced. (1997)
Seatbelts/safety: Some owners have complained of excessive shoulder belt slack. (1997-98)

NHTSA Recall History

1997-98: Front shoulder belts might twist, becoming jammed in retractor.
1998-99: Fuel-pressure regulator can leak leading to vehicle backfire and, potentially, a vehicle fire.
1999: A few cars may have been built with incorrect brake components, and could pull to one side during braking.
1999: Brake booster to pedal assembly attachment nuts on some cars may be loose.
2000: Due to internal fluid leakage in some cars, rear brake proportioning, ABS, traction control or stability control may not perform as designed.
