HAD BATTERY CHECKED WASNT THAT!!!! THEY TOLD ME ELECTRICAL ISSUES NOT SURE WHAT ONLY HAD VEHICLE 3 MONTHS!!! I HAD HAD 2004 TRAILER BLAZER BEFORE THIS SAME ISSUES!!!! ONLY HAD IT 2 MONTHS AND TRANSMISSION WENT OUT PD THAT THEN ONCE AGAIN ELECTRICAL PROBLEMS!!!!!”

“TL* THE CONTACT OWNS A 2002 GMC ENVOY. THE CONTACT STATED THAT THE INSTRUMENT PANEL WAS INOPERABLE. THE VEHICLE WAS NOT TAKEN TO BE DIAGNOSED NOR REPAIRED. NEITHER THE DEALER NOR THE MANUFACTURER WERE CONTACTED. THE FAILURE MILEAGE WAS 313,000.”

“MY RIGHT WINDOW PASSENGER SIDE WINDOW WOULD NOT GO UP SO I TOOK IT TO A SHOP. HE TOOK THE PIECE WHERE I CONTROL THE WINDOW OFF AND IT HAD CAUGHT ON FIRE. IT WAS ALL MELTED & CORRODED I HAVE PICTURES”

“I BEGAN TO HAVE ISSUES WITH MY HEADLIGHTS, LOW AND HIGH BEAMS, FLICKERING OFF AND ON AT RANDOM FOR ABOUT 4 MONTHS UNTIL MY BRAKE LIGHTS STARTED TO DO THE EXACT SAME 7 MONTHS AGO AND NOW THEY HAVE QUIT WORKING ALL TOGETHER! I HAVE TAKEN THIS SUV TO 4 DIFFERENT SHOPS NOW, AND NOBODY HAS BEEN ABLE TO FIGURE OUT WHY THIS IS HAPPENING. THE LAST MECHANIC WHO ATTEMPTED TO FIX THE ISSUE, SAYS HE FOUND AN OLDER RECALL ON THE ORIGINAL MANUFACTURED TAG LIGHTS BEING MALFUNCTIONED TO THE POINT IT CAUSES ISSUES WITH THE FRONT AND BACK LIGHTS. THE MAN SHOWN ME THE INFORMATION ON THIS RECALL, SEEING THE PART # IS LISTED ON THERE, I COMPARED IT TO MINE AND A NEIGHBOR'S 2002 ENVOY; WHICH BOTH OF OUR ENVOYS HAVE THESE MALFUNCTIONED PARTS. GM HAS NOT CONTACTED US BACK, AND WE'RE AT A LOSS BECAUSE IT'S A PART NEEDED FROM THEM DIRECTLY. WE HAVE SPOKEN TO MANY ENVOY OWNERS ON A WEB FORUM, AND THERE ARE HUNDREDS MAYBE THOUSANDS OF ENVOYS OUT THERE WITH THESE SAME ISSUES, CAUSING ACCIDENTS ON THE ROAD WAY TOO OFTEN! IT'S DANGEROUS, AND NOBODY WILL HELP WITH THIS IRRITATING ISSUE!”

“TL* THE CONTACT OWNS A 2002 GMC ENVOY. THE CONTACT STATED THAT THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC FOR THE ELECTRICAL SYSTEM DRAINING THE BATTERY. THE CONTACT HAD REPLACED THE BATTERY SEVERAL TIMES. THE CONTACT STATED THAT AN UNKNOWN GMC DEALER WAS CONTACTED BUT FAILED TO DIAGNOSE THE FAILURE DUE TO THE DIAGNOSTIC FEES. THE CONTACT MENTIONED THAT THE INSTRUMENT PANEL POSSIBLY NEEDED TO BE REPROGRAMMED AND WAS DONE BY THE PREVIOUS OWNERS. THE FAILURE MILEAGE WAS 175,000.”

“1: PASSENGER SEAT BELT LIKES TO SUFFOCATE MY PASSENGERS UNTIL THEY RELEASE RHE SEAT BELT AND REBUCKLE. 2: BOTH DIM HEADLIGHTS WENT OUT, CHECKED RELAYS, FUSES, AND BULBS NOTHING HAS WORKED. THEN FOUND OUT MY 2 BRAKE LIGHTS ARE OUT ALONG WITH THE DIMS AND NOT SURE WHAT IS CAUSING THIS PROBLEM.”
