My vehicle consumes oil in a very large amount. This has been happening since I bought the vehicle. Have had it checked numerous times. No oil leaks, no bad parts. I have to add 1 quart of oil every week to my car and I only drive locally. Mechanic states it is a common issue with this make and model of car. Nothing can be done except check oil levels daily. This is costly over time and worries me that if I dont keep a watch then my oil level will be too low and my engine will blow up. Blogs have also verified other owners have the same issue. Need something done about this issue. Why isn't there a recall to fix issue?

Several times this has happened. I am driving and all of a sudden my car stops and I get a message that says Hybrid System Warning, Safely Stop and Do Not Drive. The car will coast to the side of the road at times and other times it won't. I have taken it to the Holler Hyundai dealer in Winter Park FL and they told me nothing was wrong with it. They had my car for less than an hour. I told them there was no way they could have fixed the issue but they said they did. Obviously they didn't fix it because it has happened several times since then. Now my car will not even move. It starts up, radio works, AC works, just will not move. It is at the Sanford Hyundai service shop waiting for them to tell me what it

Started the vehicle and shifted into gear and the vehicle started to shake and vibrate. The engine was knocking and running very poorly. Within a minute the service engine light came on. We were able to get the vehicle back in to the garage. I opened the hood and checked the oil. The dipstick was dry. The end of the dipstick appeared to have burnt oil on it. I took some pictures and a video of this. I did some simple online research and found numerous cases an articles pertaining to this situation. I have had all my routine maintenance performed at a dealership since it was purchased. I added 3 quarts of oil and now the dipstick reads half-way between Low and Full. I started the vehicle and the engine still shakes and runs poorly. The nearest Hyundai dealer is over 20 miles away and I don't think the vehicle will make it that far. Do I even have any other options than trying to "limp" the car there and possibly mess more things up in the process?

since around 6/2022 been having oil issues but really didn't start getting bad till 12/2022 while driving car has rattling noise with acceleration and almost stalls due to oil light kept popping on and off come to find out I was almost out of oil. which lately i have been having to constantly check my oil due too high oil usage and keep a jug in my trunk every where I go so I don't stall on side of the road and not to mention that oil light really doesn't give warning of oil being low either. So my co worker had me check to see how fast it burns oil. we put oil in the car on a friday and by the next friday its low again and now it may 2023 and burning oil at a higher rate of me checking twice a week now. i check my car on a sunday an put oil in and it was out by thursday. this is really a hazard and very dangerous while driving because you don't know when the oil is low or out and light does't give warning and you can completely stall in traffic if you don't keep check and cause a accident and i have children and myself and family and others to watch out for. I hope this matter is taken care of quickly before someone gets hurt a recall to fix this matter is urgent

While driving on a highway, I heard a rattling sound, which could best be described as tying cans to the car and dragging them along the road. I had never heard this noise before. No safety indicator lights turned on to alert me of any issue. With minutes of first hearing the sound, a very loud pop noise could be heard, followed by immediate engine power failure. I was able to navigate off of the highway, into a more residential area. Upon the vehicle coming to a stop on its own (I was not able to apply the brakes at all), a dark cloud of smoke starting coming from underneath the hood. Seconds later, it burst into flames. I was able to safely exit the vehicle with my dog, but if traffic were any heavier, there would have been no safe way for me to get off the road and to a safe location

I have a used 2015 Hyundai Sonata that I purchased from a Hyundai dealership in December 2021 (due to the chip shortage, I had to purchase used). A few months later In June 2022 I was driving on the freeway and my car felt like it was losing acceleration. I was already planning to exit the next exit to go to my destination and as I was exiting and came to stop at the red light before I could then turn right.. my car started to violently shake. Ultimately, after going to my own car place the following day and them determining that the fuel injectors and the computer were not talking, I had it towed to Hyundai where after another 4 days they also determined it was that problem and they replaced the computer under warranty. Well today I was again on the toll road / freeway and I was in the fast lane, I suddenly felt a strong jolt and my malfunction light came on and it was blinking on the dash, I knew not to drive it based on the light and as I steered to the right shoulder to slow / stop and call AAA I could feel my car just lightly shaking again. My car is now at the same Hyundai dealership where I purchased it and I-??m waiting for diagnostics on the problem. Before this all happened, the first time in 2022 I was having sporadic issues with pressing the start button and there was a bit of a delayed start at times, even after the computer was replaced I-??ve still had hiccups with the start button at times but it-??s been very sporadic and it has never been a starter issue (had my car place already check that). So I-??m now waiting to hear if the computer indeed failed for a second time. They cannot assess my car until Monday or Tuesday at the dealership (today was a Friday, my car was towed there at about 11am today). If the computer did fail again, it lasted about 14,000 miles before it just died again. Quite frustrated at the moment. I already contacted Hyundai corporate and opened a second case today regarding all of this.

In September 2022, we noticed a noise coming from under the car hood. Sounded like a thump as we accelerated. We took it to the Hyundai-??s service department and was told that they couldn-??t hear anything or find a problem. They changed my oil. We continued to hear a noise but thought it wasn-??t a concern. In February, a fairly new tire went flat and we returned to the Hyundai service department. I received a call later and was told that they could hear a noise and they checked, and my oil was extremely low. They topped it off and told me to return in a thousand miles to see if it was still burning oil. If it was burning significant oil at that point, they would seal it and begin the Hyundai oil consumption test. At about 600 miles, I could smell a strong plastic burning odor and we checked the dip stick and the oil was barely detectable. We called Hyundai and was told there was nothing they could do and we have to go the full thousand miles to determine if we qualify for the test. We are concerned are engine is going to stall, burn up or catch fire in our garage. They told us, we couldn-??t get are car in to be looked at until the end of March. After doing some research, I am aware that there is a current class action lawsuit against Hyundai for this issue.
