Owners have filed 277 complaints with NHTSA about the 1998 Buick Park Avenue, and it carries 2 recalls. These are owner allegations rather than confirmed defects, but the pattern of what people complain about is the most useful signal a used buyer has.

NHTSA complaint: Structure
NHTSA lists 2 recall campaigns for the 1998 Buick Park Avenue. Recalls are free to have fixed at a franchised dealer regardless of who owns the car now, but only if they were never done, so check the VIN of the specific car rather than trusting the model.
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH 3800 V6 (L36) ENGINES AND CERTAIN DELPHI FUEL PRESSURE REGULATORS, THE REGULATORS HAVE A MUCH HIGHER THAN USUAL RATE OF FUEL LEAKS. A LEAK CAN ALLOW FUEL TO ENTER THE INTAKE MANIFOLD THROUGH A VACUUM LINE. IF THE ENGINE DOES NOT START WHEN CRANKED, THE
Risk: THE BACKFIRE CAN RUPTURE THE INTAKE MANIFOLD. THE RUPTURE OF THE INTAKE MANIFOLD CAN DISPLACE A FUEL LINE, PULLING AN INJECTOR OUT OF PLACE, AND CAUSING A FUEL LEAK AND POSSIBLE FIRE.
Fix: DEALERS WILL INSTALL NEW FUEL PRESSURE REGULATORS WITH IMPROVED DIAPHRAGMS. THE RECALL WILL BE CONDUCTED IN PHASED MAILINGS. PHASE 1 BEGAN ON JUNE 30, 2004, AND PHASE 2 BEGAN ON SEPTEMBER 30, 2004.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. SOME OF THESE VEHICLES HAVE FRONT SEAT SHOULDER BELTS THAT MAY TWIST, ALLOWING THE WEBBING TO BECOME JAMMED IN THE RETRACTOR.
Risk: WHEN THE SHOULDER BELT WEBBING BECOMES JAMMED IN THE RETRACTOR, THE BELT MAY BE UNUSABLE.
Fix: DEALERS WILL INSPECT FOR THE PRESENCE OF UPDATED FRONT SHOULDER BELT BEZELS AND WHERE NECESSARY, INSTALL NEW FRONT SEAT SHOULDER BELT OPENING BEZEL KITS.

What stands behind each score for this car:
Owners have filed 277 complaints with NHTSA for this model-year, and engine and engine cooling is the most reported area with 91 of them (33%). There are 2 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 79/100 (good) from NHTSA recall campaigns and complaint density. That figure is a raw complaint count, not yet adjusted for sales volume, so a high-volume model scores worse than it deserves.
AVOIR scores its longevity 78/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 1998 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: be careful, because the numbers are mixed and the complaint record is worth reading before you commit. Its overall ownership score is 68/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
Sources: NHTSA recalls and complaints, EPA fuel economy, IIHS awards, and live market listings. A score describes a model-year, not the individual car in front of you. Get a pre-purchase inspection.
