NHTSA lists 2 recall campaigns for the 1996 Buick Riviera. 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.
A BACKFIRE DURING ENGINE STARTING CAN CAUSE BREAKAGE OF THE UPPER INTAKE MANIFOLD.
Risk: THIS CONDITION CAN CAUSE A NO-START CONDITION AND POSSIBLY AN ENGINE COMPARTMENT FIRE.
Fix: DEALERS WILL UPDATE THE POWERTRAIN CONTROL MODULE PROGRAMMING. UNTIL THE CAMPAIGN REPAIR IS MADE, THE VEHICLE HOOD SHOULD BE SHUT WHENEVER STARTING THE VEHICLE TO REDUCE THE CHANCE OF PERSONAL INJURY.
THESE VEHICLES WERE ASSEMBLED WITH A MALFUNCTION ALARM, LIGHTING AND LOCKING (MALL) MODULE THAT CAN CONTAIN A DAMAGED CAPACITOR. IF THE CAPACITOR IS DAMAGED, THE "KEY IN THE IGNITION" WARNING CHIME AND THE DRIVER SEAT BELT UNBUCKLED WARNING CHIME AND INDICATOR LAMP MAY NOT WORK. THIS DOES NOT MEET T
Risk: CONSEQUENCE OF NON-COMPLIANCE; THE DRIVER MAY NOT BE AWARE THAT THE KEY WAS LEFT IN THE IGNITION OR THAT THE SAFETY BELT WAS NOT BUCKLED.
Fix: DEALERS WILL INSPECT AND, IF REQUIRED, REPLACE THE MALL MODULE.

What stands behind each score for this car:
Owners have filed 55 complaints with NHTSA for this model-year, and fuel system is the most reported area with 7 of them (13%). There are 2 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 86/100 (excellent) 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 81/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 1996 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: worth a look, because a solid ownership case with specific caveats below. Its overall ownership score is 71/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
