NHTSA Complaint #11551206 — 2017 HYUNDAI SANTA FE

Engine made knocking noises and was towed to a mechanic. Mechanic discovered metal shards in the oil pan and all signs pointed to being well maintained. We bought used from CarMax and are the 2nd owners. Mechanics best guess is engine failure due to defect and high oil consumption with no signs of leaks. No codes, no check engine light, no low oil pressure light. No warning. Oil changes were completed by us and valvoline at regular intervals. Safety risk of engine failure while driving and causing an accident. Car was successfully pulled to the side of the road. Hyundai dealership unable to help with repair assistance as we are second owners and warranty did not transfer. Researched community chat forums and this seems to be a common issue for this engine to fail.
