Certain passenger vehicles have hazard warning switches that may experience solder joint cracking caused by rapid temperature transitions and the soldering process. If solder joint cracking occurs and results in an open circuit, the turn signals/hazard lamps become intermittent or inoperative.
Dealers will replace the hazard warning switch. Owner notification began on February 5, 2004. Owners should contact Chevrolet at 1-800-630-2438, Pontiac at 1-800-620-7668, or Oldsmobile at 1-800-630-6537.
