NHTSA Complaint #11459684 — 2014 HYUNDAI ELANTRA

I purchased this vehicle from Duncan Hyundai in Christiansburg VA on 11/13/2021. When I purchased the vehicle it had 90,588 miles on it. I started hearing a knocking sound coming from the engine in late January - early February 2022 only 2-3 months of having the car. The engine light came on and the car was also smoking some. We checked the oil in the vehicle and it was empty. We put a quart in the vehicle to take it to the dealership. We were told that yes, the vehicle in fact did not have any oil in it. I asked them well were did the oil go? Is there a leak or something? Oil just doesn't disappear like that. The mileage on the car at that time was 93,543. It wasn't even due for an oil change. I was told that this particular vehicle burns oil and every thousand miles & we will have to add a quart to it at that time. We are now monitoring that. I see that Hyundai has an open recall for this same knocking sound and burning oil on the 2019-2020 models. My 2014 is having the same problem and now I will have to take it back and forth to the dealership to make sure they monitor and hopefully eventually fix the problem for me. Again all they said at the moment was add a quart every thousand miles. In a month period (March) I have had to add 2.5 quarts to the vehicle. The vehicle now has a total of 94,916 miles on it. In a total of 1,373 miles it burned 2.5 quarts. What the dealership said about a quart every thousand miles was not correct. It has burned double that amount.
