An inoperative brake lamp will not convey the driver's intention of stopping to drivers in following vehicles, and an inoperative rear turn signal lamp will not convey the driver's intention to turn to drivers in following vehicles. Both of these failures can increase the risk of a crash.
On certain sport utility vehicles, vibration and heat may cause the tail lamp/stop lamp bulb to loosen in its socket. If this occurs, the bulb may flicker and eventually become inoperative.
Dealers will inspect the tail lamp/stop lamp assemblies, and if necessary, replace them. The recall began on November 22, 2004. Owners should contact Chevrolet at 1-800-630-2438, Oldsmobile at 1-800-630-6537, Buick at 1-866-608-8080, or GMC at 1-866-996-9463.
