Our reliability study for this generation Buick Park Avenue includes details on average repair costs, manufacturer recalls, and everything you need to know to gauge the long-term reliability of this generation Buick Park Avenue .
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:
Coolant loss via plastic intake manifold is corrected by installing upgraded manifold and gaskets plus new PCV kit. (1997-04)
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)
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)
