Open the full vehicle complaint log (all categories)I HAVE HAD TWO GM TRUCKS THAT HAVE HAD AN ISSUE WITH THE LOW BEAM HEAD LIGHTS NOT FUNCTIONING. IN BOTH CASES IT HAS BEEN THE MULTIFUNCTION SWITCH ON THE STEERING COLUMN. THE CHEVY C2500 HAPPENED ABOUT 18 MONTHS AGO. THE 2001 YUKON HAPPENED RECENTLY. *TR
WHILE DRIVING AT NIGHT, CONSUMER PUSHED DOME LIGHT OVER RIDE BUTTON, IMMEDIATELY HEADLIGHTS AND DASH LIGHTS WENT OUT. VEHICLE WAS TAKEN TO DEALER, GMC WAS CONTACTED. MANUFACTURER STATED THIS WAS THE DESIGN OF THE VEHICLE. TO PRESS AGAIN 4 TIMES WITHIN 6 SECONDS. THIS WOULD PROMPT ALL LIGHTS TO COME ON AGAIN. THERE IS A SECTION IN OWNERS MANUAL WHERE THIS FACT IS MENTIONED, BUT NOT IN CLEAR TERMS.*AK DEALER COULD NOT FIX. *TT
CONSUMER'S VEHICLE DOESN'T HAVE ANY TAIL LIGHTS TO ALERT VEHICLES OR TRAFFIC BEHIND OF A SUDDEN STOP OR JUST BEING THERE. BRAKE LIGHTS ONLY COME ON TO INDICATE A STOP. DEALER REPLACED THE BODY CONTROL MODULE, BUT IT HASN'T BEEN CORRECTED. *AK
