NHTSA Complaint #10898532 — 2016 GMC YUKON XL

BOUGHT SUV 6/25/2016 THE SAME WEEKEND THE ENGINE TURNS OFF AFTER A LEFT OR RIGHT TURN :IT HAS HAPPENED 3 TIMES SO FAR. 4 WEEK OLD 2016 YUKON DENALI XL, HAS STALLED 3 TIMES IN LAST 4 WEEKS, ENGINE CUTS OFF AFTER A LEFT OR A RIGHT TURN ONLY AFTER A SHORT DRIVE OUT OF HOME. THE SUV HAS TO BE RESTARTED! COULD HAVE EASILY HAD AN ACCIDENT OR WORSE. I TOOK IT TO THE WESTPOINT GMC DEALER, 3 TIMES. 1ST TWO TIMES, ALL OF SERVICE DEPTARTMENT COULD NOT DIAGNOSE THE PROBLEM. TODAY, AFTER A STALL, I CALLED ONSTAR, WHO RAN A DIAGNOSTICS TEST,BUT ONSTAR FOUND NOTHING OF VALUE , I LEFT IT AT DEALERSHIP AND CONTACTED DISTRICT MGR. MATT TILLSON . I WAS TOLD THAT THEY WOULD ESCALATE THE ISSUE. I DID TELL DEALER THAT GMC AND DEALERSHIP WOULD BE AT FAULT IF VEHICLE IS INVOLVED IN AN ACCIDENT AND STALLS NOR STOPS WHILE I AM DRIVING. I DID NOT WANT THE VEHICLE BACK WITHOUT THE PROBLEM HAVING BEEN FIXED. ITS DAY 6 TODAY. I NEED TO MAKE IT ABSOLUTELY CLEAR, I WILL NOT TAKE THE VEHICLE BACK UNTILL THE PROBLEM HAS BEEN DIAGNOSED, AND FIXED. I DO NOT WANT ME OR MY FAMILY OR GM SERVICE EMPLOYEE INJURED, OR WORSE, OR TO BE INVOLVED WITH A POSSIBLE ACCIDENT IN MY GMC YUKON DENALI XL. A FIELD SERVICE ENGINEER SHOULD HAVE BEEN ON THIS CASE ALREADY ! WILL IT TAKE AN ACCIDENT, OR INJURY BEFORE SOMEONE GETS ASSIGNED?
