2016 GMC YUKON DENALI XL Engine Problems

I HAVE A 2017 YUKON XL DENALI. IT HAS 6K MILES. I PURCHASED IT NEW JUNE OF 2017.I WAS DRIVING THROUGH A PARKING LOT,WENT OVER A SPEED BUMP AT ABOUT 3 MPH AND THEN I NOTICE THE AC TURNED OFF.THEN I REALIZED THE RPM WAS AT 0 AND WHEN I PUSHED THE GAS PEDAL THERE WAS NO RESPONSE. THE ENGINE HAD STALLED OUT WHILE DRIVING. I TOOK THE CAR IN FOR SERVICE AND THEY WERE UNABLE TO REPLICATE THE ISSUE. THERE WERE NO CODES STORED ON A CAR I'M TOLD HAS ABOUT A BAZILLION COMPUTERS (IMAGINE THAT) AND THAT THERE WERE NO OTHER CUSTOMER COMPLAINTS OR "SERVICE BULLETINS" STATING IT WAS A KNOWN ISSUE. APPARENTLY IF YOUR GMC SERVICE DEPT CAN'T REPLICATE THE ISSUE...THE CAR IS OBVIOUSLY FINE. I TOLD THEM I'M NOT TAKING THE CAR BACK. THEY WOULD NOT ALLOW ME TO CONTINUE USING A LOANER NOR DID THEY...

MY 2016 GMC YUKON XL DENALI HAS AN INTERNAL ENGINE OIL LEAK THAT REQUIRES ME TO ADD ABOUT A QUART OF MOTOR OIL EVERY 2,000-3,000 MILES, WHICH EQUATES TO ABOUT 2-4 QUARTS OF OIL BETWEEN THE RECOMMENDED OIL CHANGE INTERVALS (EVERY 7,500 MILES). MY GMC DEALERSHIP HAS PERFORMED MULTIPLE OIL CONSUMPTION TESTS AND HAVE CONCLUDED THAT I HAVE AN INTERNAL ENGINE OIL LEAK, BUT AM WITHIN GMC'S OIL CONSUMPTION STANDARDS. SINCE I AM WITHIN GMC'S OIL CONSUMPTION STANDARDS, THEY CANNOT ADDRESS / REPAIR THE OIL LEAK. I AM FILING A COMPLAINT SINCE THIS MAY RESULT IN FUTURE ENGINE ISSUES / MALFUNCTION. AFTER RESEARCHING ONLINE, IT APPEARS THAT THERE ARE COUNTLESS OTHERS THAT HAVE EXPERIENCED THE SAME PROBLEM WITH GMC, CHEVY AND CADILLAC SUV'S / TRUCKS.
