“MY 2013 BUICK REGAL VIN:[XXX] IS HAVING ONE OF THE 3 RECALL ISSUES THAT YOU HAVE LISTED. ISSUE #13V173, MY CAR WILL NOT START AND THE BATTERY IS LOSING POWER. I REPLACE THE BATTERY AND WAS INFORMED THAT THE BATTERY IS GOOD AS WELL AS THE ALTERNATOR BUT WHEN I TOOK MY CAR TO BUICK, I WAS TOLD IT WAS THE GENERAL CONTROL MODULE. UNFORTUNATELY, THE NHTSA DOES NOT HAVE MY VIN LISTED AS ONE OF THE AFFECTED 2013 REGAL MODELS BUT IN MY OPINION, IT SHOULD BE LISTED. I AM ATTACHING A SCREENSHOT OF THE PART AND REPAIR LISTED FOR MY VEHICLE. THE PART IS $929 TO REPLACE. PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).”
