Brake Lights and Turn Signals May Not Work

The brake lights and rear turn signals may stop working due to insufficient contact between the socket and bulb.

Dealers will inspect the rear lamp bulb socket assemblies and apply grease or replace them if needed. The recall began January 18, 2005. The GM recall number 04083.
