2018 Hyundai Kona: excessive oil consumption

Filed Apr 9, 2026 · Acceleration, Engine · MD

The Kona barely wants to accelerate and stalls out while driving. Even though I recently got a oil change there’s oil consumption and the oil is black as if I never got a oil change. I took it to a hyundai dealer ship, i told them what was wrong they said it’s the timing belt. When that’s not the issue. I recently took it to a mechanic to get a third opinion and to see and fix what is wrong. He declined fixing it saying there’s more to it that is wrong and looks like there’s an engine defect and even complained that the oil was so black. I told him that doesn’t make sense because I’ve been getting my oil consistently. He couldn’t fix it. So now I’m stuck with a vehicle that barely drives and stalls out while I’m on the road and it keeps burning more oil. No one knows what is wrong with it.

My vehicle started was burning oil having to add oil frequently. Then a knocking noise started coming from the engine (2.0 L MPI NU).It began to have trouble starting and was not accelerating properly and the check engine light came on . Within two days I brought my car to my mechanic and he stated that there was no sign of an oil leak and felt it was a deeper problem. I brought it to a Hyundai dealership and they stated that the engine needed to be replaced/rebuilt. I feel that the lack of acceleration could have been a safety issue on the highway as it could have prevented me from passing in a timely fashion or just lose all power in traffic. There is an active recall for this type of engine starting with model year 2019.

Prior to 100,000 miles, I noted knocking in the engine, especially while going uphill. The knocking would appear and disappear, possibly with oil change intervals. No check engine light ever appeared. After 100,000 miles, the engine progressively began knocking, losing power, and eventually stalling on the road occasionally. I have had to put on my hazards and restart my car. One time, I was barely able to pull over to the side. Again, no check engine light ever appeared. I have several videos of the vehicle in motion with audible knocking, and almost stalling. The videos show the dashboard with NO check engine light appearing. There was no sign of oil loss. No smoke. No oil stains under the vehicle. I was due for an oil change when the knocking and stalling became severe. I visited the dealer and informed them of the engine issues. They performed an oil change. And then could not reproduce the problem I experienced. Told me to come back if it happened again. This sounded odd to me given the severity of the knocking and stalling. Or it signaled to me that an oil change including refilling the oil solved the issue. Long story short. An oil consumption test was performed. The engine is consuming oil. I am scheduled for combustion chamber cleaning per the Technical Service Bulletin, as mentioned by the service rep. I am not confident that this will fix the problem. Given that this is the same / similar engine as the recalled 2018-2021 Kona for the same / similar issue. Oil consumption.

I am having issues with my oil consumption and my car is going through a quart of oil every 1-1.5 weeks. There have been similar recalls on the 2019 Kona’s which have the same 1.6L 4-cylinder engine. My car is currently a little over 126,000 miles

My engine started shuddering and stalling out on me. This was very dangerous as the car would stall out at street lights and intersections. The check engine light only came on after the car stalled out and has not stayed on during the times that it stalls out. When I went to get a mechanic to check it out they said that they had seen many Hyundai and Kia cars that had the same issues. The issue was oil consumption. It was consuming oil faster than it should have, even though I was regularly getting my oil changed. This lead to a problem with my pistons. Now the engine needs to be replaced. But Hyundai won’t cover it because there is no recall on it and the power train warranty only last for the first owner. Is there any way we can request for a new recall on this vehicle as it is clearly a problem that Hyundai is having.
