- Summary
- 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.
- Consequence
- 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.
- Remedy
- 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.
- Notes
- GM recall no. 04087. Customers can also contact the national highway traffic safety administration's auto safety hotline at 1-888-dash-2-dot (1-888-327-4236).

Has your Buick been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Buick dealer can also check your VIN. Recall repairs are free.
