NHTSA Complaint #10713206 — 2011 GMC ACADIA

WHILE DRIVING AT SPEEDS RANGING FROM 30 MPH TO 60 MPH, THE ENGINE BEGINS TO MISS, ESPECIALLY UPHILL. THE VEHICLE BEGINS TO SHAKE TERRIBLY. WHEN I CONTACTED THE DEALERSHIP REGARDING THE ISSUE, I WAS ASKED IF THE CHECK ENGINE LIGHT WAS ON. IT WAS NOT BUT THE DEALERSHIP HAD ME BRING IT IN ANYWAY. THIS VEHICLE HAS BEEN IN THE SHOP THREE OR FOUR TIMES NOW. I HAVE PAID TO HAVE THE FUEL SYSTEM CLEANED AS WELL AS THE SPARK PLUGS AND PLUG COILS REPLACED. THESE ARE EXPENSIVE PROCESSES NOT COVERED BY EXTENDED WARRANTIES. IN THE END, I HAVE BEEN TOLD BY THE DEALERSHIP THAT UNLESS A CHECK ENGINE LIGHT COMES ON TO 'MAP' THE PROBLEM, THEY CAN'T HELP ME. *TR
