The 1997 Buick Park Avenue has 4 recalls, all involving seat belt failures that can leave occupants unprotected in a crash, including front shoulder belts that can jam and a rear center belt anchor that can pull free under crash loads.
The front shoulder belt issue affects both front seating positions: the webbing can twist and become lodged in the retractor mechanism, leaving the belt unable to extend or retract properly and effectively unusable. An occupant who cannot buckle the belt, or who finds it already jammed, would have no restraint in a collision. The rear center seat belt concern is a separate problem involving the anchor bolts that secure the belt to the vehicle structure. These bolts were not properly installed during assembly, meaning the attachment point can give way under the force of a crash rather than holding the occupant in place. Both issues cover the Park Avenue and Park Avenue Ultra.
