NHTSA Complaint #11298262 — 2014 GMC SIERRA 2500

I WENT TO OPEN THE ELECTRIC REAR SLIDING WINDOW, AND IT STARTED TO OPEN, THEN IT STOPPED HALFWAY OPEN, WITH A BLACK CABLE HANGING DOWN. MY TRUCK ONLY HAS ABOUT 23,000 MILES ON IT, AND HAVE ONLY OPEN IT LESS THAN 12 TIMES. IT STILL DOESN'T WORK. I TRIED TO COMPLAIN TO GENERAL MOTORS CORP. CUSTOMER SERVICE, WITH THEM TELLING ME THAT IT WOULD COST ME $542.65 WITH GM ASSISTANCE. THIS IS REDICULOUS. IT MUST HAVE BEEN INSTALLED WRONG, OR IT WAS DEFECTIVE. I WAS STOPPED AT MY HOUSE WHEN THIS HAPPENED. I'VE MADE SEVERAL CALLS TO THE CUSTOMER SERVICE, SPEAKING TO SEVERAL REPRESENTATIVES, AND I KEEP GETTING THE SAME ANSWER, THATI WILL NEED TO PAY TO HAVE THE WHOLE WINDOW REPLACED (NOT FIXED). I WOULD LIKE TO KNOW IF THERE ARE OTHER COMPLAINTS ABOUT THIS SAME ISSUE FROM OTHER CUSTOMERS. THE DEALER THAT QUOTED ME THE COST WAS SANBORN CHEVROLET, IN LODI, CA.
