2011 Buick Regal RecallsFront Seat Height Adjuster
The driver's and/or passenger's seat may suddenly drop to its lowest position because a bolt securing the height adjuster can fall out. This unexpected movement of the driver's seat could cause a distraction, increasing the risk of a crash. Dealers will replace the height adjuster bolts in both front seats to correct this concern.
The front turn signals are equipped with two bulbs on each side. If one bulb fails, the driver would not be made aware of the loss of light function, which could create a safety hazard. Dealers will update the body control module software free of charge to resolve the concern.
