NHTSA Complaint #11154524 — 2013 GMC TERRAIN

POTENTIAL OIL CONSUMPTION ISSUES. IN MAY 2018 NOTICED A KNOCKING/RATTLING IN ENGINE WHILE ACCELERATING AT SLOW SPEEDS. NOISE GREW LOUDER AND MORE CONSISTENT OVER THE NEXT FEW WEEKS. ON BOARD COMPUTER STATED REMAINING OIL LIVE WAS OVER 30%, HOWEVER NO OIL REGISTERED ON DIPSTICK. ADD OIL AND NOISE STOPPED. I SCHEDULED AN APPOINTMENT (JUNE) WITH THE DEALER TO HAVE THE ISSUE INVESTIGATED. THEY TOLD ME IF IT OCCURS AGAIN, NOT TO ADD OIL, RATHER BRING IT IN FOR A CONSUMPTION TEST. THEY DID NOT TELL ME HOW LOW MY OIL LEVEL WAS. NOVEMBER 2018 THE NOISE RETURNED. IMMEDIATELY TOOK VEHICLE TO DEALER FOR RECOMMENDED OIL CONSUMPTION TEST. INFORM BY DEALER THAT VEHICLE WAS NO, LONGER COVERED BY ANY WARRANTY, THEY COULD NOT DO THE TEST. OIL CHANGED (EVEN THOUGH ON BOARD COMPUTER STATED 48% OIL LIFE REMAINING). READING OTHER REPORTS REGARDING THIS POTENTIAL ISSUE, WANTED TO ADD ONE MORE.
