The 1985 Buick Somerset has 3 recalls, the most serious involving a carburetor return spring that can fail and leave the throttle stuck open, causing the vehicle to keep accelerating even after the driver lifts off the pedal.
The electrical system also has a concern: the headlamp switch panel can build up excessive heat and cause the headlights to cycle on and off unpredictably, cutting visibility without warning during nighttime driving. On the structural side, this recall only affects two-door models: cracks can develop in the body pillar around the door striker bolt, and if left unrepaired, those cracks can spread to the point where a door flies open in a crash.
