Excessive oil consumption. I bought the car in used condition back in June 2019 with approximately 82,000 miles on it. It currently has 125,000 miles on it and only recently have I been experiencing this issue. I change the oil on this car every 5,000 miles or so since I do plenty of commuting for work. The last time I took my car to get the oil changed before I noticed the problem was in December 2020. I never bothered to check the oil because I had complete confidence that the oil was topped off at every oil change. However, I started noticing that the car felt forced whenever I tried to accelerate. I also started noticing a subtle rattling noise coming from under the hood whenever I would try to accelerate. I had a mechanic check my car in January 2021 when he checked the oil levels and pointed out that there was nothing on the dipstick. What is even stranger is that no dashboard light had come on. I had driven the car approximately 2,500 since the the oil change in December and it was already empty. I checked under the car where I park both at home and at work and there are no oil spills on the ground. I've read several forums where people have the same issue with older models of this car and there are recalls for those models. However, I've also come across forums where people are experiencing the same issue with newer models such as mine. I will be taking this car to a Hyundai dealer to address the issue. But at this point, I have to add about quart of oil every just to keep it full and to prevent the engine from seizing while I am driving. This is a huge concern.
