NHTSA Complaint #11269545 — 2012 GMC TERRAIN

I RECEIVED AN OIL CHANGE AT THE DEALERSHIP, WITHIN LESS THAN A THOUSAND MILES I CHECKED MY OIL AND IT WAS COMPLETLY DRY,NO OIL ON THE DIPSTICK AT ALL. I ADDED 2 QUARTS OF OIL DURING THAT WEEKEND AND THEN WENT TO DEALERSHIP THE NEXT DAY. WHEN I WENT TO DEALERSHIP THEY TOLD ME MY OIL WAS ABOUT .5 QUART OVERFILLED AFTER HAVING AN OIL CHANGE 1000 MILES PRIOR, ADDING 2 QUARTS OF OIL ADDITIONALLY AND ONLY RETURNING TO HAVE THEM CHECK IT A DAY LATER. SO LEAVING THE DEALERSHIP I WAS TOLD TO DRIVE 1000 MILES THEN RETURN TO HAVE THEM CHECK IT. AFTER 1000 MILES UNRETURNED AGAIN AND THEY TOLD ME MY OIL WAS TOO LOW. THEY THEN TOLD ME TO DRIVE ANOTHER 1000 MILES AND RETURN ONCE AGAIN FOR ANOTHER CHECK AT WHICH TIME THEY AGAIN FILLED MY OIL TO THE RECOMMENDED AMOUNT. I'M ONLY ST ABOUT 500 MILES INTO THE 2ND CHECK AFTER DRIVING 1000 MILES AND I CHECKED MY OIL AT HOME THIS WEEKEND AND IT'S ALREADY LOW. VERY FRUSTRATED BECAUSE IF I WASNT CHECKING IT, AND I WAS DOING WHAT INWAS SUPPOSED TO BY GETTING OIL CHANGES THEN IT SEEMS LIKE IN LESS THAN 500 I'D BE LOW AND LIKELY BLOW MY ENGINE IF I CONTINUE DRIVING NOT WORRYING ABOUT CHECKING CAUSE I SHOULD HAVE PLENTY OF OIL GIVEN I HAD RECENTLY HAD AN OIL CHANGE AND WAS WELL WITHIN THE LIMITS BEFORE NEEDING TO RETURN FOR MY NEXT SERVICE. DURING THE FIRST WAITING PERIOD TO DRIVE 1000 MILES MY CAR STARTED KNOCKING IN THE ENGINE, WAS JUST DIEING WHEN I WOULD TAKE MY FOOT OFF BREAK TO ACCELERATE AND OVERALL WAS RUNNING VERY ROUGH. RECENTLY WAS TOLD SOME OF THE CODES THAT WERE COMING UP WHEN I HAD IT HOOKED UP FOR THE CHECK ENGINE LIGHT BEING ON, THAT THE CODES COULD BE RELATED TO THE OIL CONSUMPTION AND PROBLEMS IT WAS CAUSING FOR REST OF CAR.
