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 tire pressure monitoring system is designed to illuminate the tire pressure warning light when the tire pressure in any one tire is 25% below the recommended cold tire pressure. On these vehicles, the light will not illuminate until the tire pressure is more than 25% below the recommend cold tire pressure. Underinflated tires can result in the tire overheating, which could lead to a blowout and a possible crash. Underinflated tires also affect tire wear, vehicle handling, and fuel economy. Dealers will update the Body Control Module software to correct this concern. The General Motors recall number is 11261.
