14823 - SPECIAL COVERAGE. ON CERTAIN 2007-2012 MODEL YEAR GMC ACADIA VEHICLES EQUIPPED WITH HIGH-INTENSITY DISCHARGE (HID) HEADLAMPS (RPO TVD), THE HEAT GENERATED BY THE DAYTIME RUNNING LAMP (DRL) MAY DEFORM THE BULB GASKET. THIS CONDITION COULD RESULT IN THE LOSS OF DRL FUNCTION AND CAUSE DAMAGE TO THE HEADLAMP ASSEMBLY; HOWEVER, LOW AND HIGH BEAM HEADLAMP OPERATION ARE UNAFFECTED. DEALERS ARE TO INSPECT THE HEADLAMP FOR DAMAGE AND REPLACE THE HEADLAMP ASSEMBLY AS NECESSARY. FOR HEADLAMPS WITHOUT DAMAGE, DEALERS ARE TO INSTALL A NEW GASKET AND REINFORCEMENT PLATE BETWEEN THE SOCKET AND THE REFLECTOR.
