NHTSA Complaint #11474630 — 2016 HYUNDAI SANTA FE

My wife and I were driving on the highway with our 4 kids in a construction zone the vehicle lost power to accelerate. We went from 70MPH all the way down to 35MPH fully pressing the accelerator pedal. We were able to coast to a spot to stop in a merge lane. Turned off. The vehicle and restarted it. It worked as normal letting us accelerate only moments later to do it again. It happened on and off multiple times so we took side streets all the way home. It worked normally for a day or two then it happened again only this time an oil light appeared. It was the first time any warning light came on no check engine or service lights prior to. We pulled over to check the oil it was completely out of oil well before her service was do as we normally do oil changes before the scheduled time. We added 3 qts at the first gas station we pulled to when we checked it. The vehicle drove normally then no sputtering like it was before. Only the next day we performed a full oil change to ensure it had adequate oil. It ran great for a day and then an awful rattle came from the engine compartment. Started as a ticking more light sounding then became a louder clanking. We since parked the vehicle in the driveway but being around 91,000 miles it doesn't qualify for Manufacturers 100,000 warranty since we bought it pre-owned at a dealer in Texas. We are currently looking into what it takes to fix it at a mechanic since Hyundai won't warranty it. After some research it seems this same rattle and engine malfunction as well as oil consumption issues has happened on many Hyundai models. We weren't aware of this before but certainly feel there is a Manufacturers issue just reporting as I'm sure there is many others out there. Thanks in advance for any help or suggestions from anyone.
