Starting in July 2023 I have noticed that the oil consumption for my car is racing through the engine. I barely make it 1000 miles before the oil is completely gone. After 2 local oil changes - I decided to take it to the Hyundai dealer where I purchased the car. This was in October - I have brought my car in 4 times for 1000 mile oil consumption tests. I had to add an additional visit due to the fact that Hyundai changed the testing standards. Now I have to bring it again today - Hyundai has not told me what the next step is other than I have to leave the car there all day - after they speak to tech support they will determine next steps. Most likely a combustion cleaning. Then I have to start the 1000 mile consumption tests again. I live 35 mins from the dealer - I have had to hire someone to take me there to leave car - and I then have to take mass transit to work. There are never any loaners because they are booked months in advance. I have had to rent numerous cars for long distance travel due to the mileage meter of 1000 miles on my car - I am not allowed to go over - if I do have to start all over again. That happened to me the first time. My car is crap at this point - I am not able to use it as I should be able to and Hyundai is giving us the run around. I have been contacted about trading it in and getting a new Hyundai - what a scam. I am not the only person - there are so many of us - follow the chats on Facebook and Reddit - nobody is helping us. The staff said if your engine seizes - that would be great. People are seizing on highways - that is very scary to me. Why is this not recalled yet?

Unknown. This has happened a couple times now. I am driving and the HEV light, engine light and battery light turn on, car won-??t brake properly and almost cause me to hit other cars and will shut off on its own on the highway. It will accelerate on its own even when trying to brake. Extremely dangerous.

I have lease this car since 1/16/2019 until 4/14/19. Start first with lower the speed and power just a little bit. Then 4/14/19 the car lower the speed by itself, start shaking up, limp, shows the engine light and the speed control ligh in conjunction with slippery control ligh then stay at "temporary engine protection mode" lossing speed and cant drive safely. Just park the car at the safe parking lot to tow at the nearest Hyundai dealer for inspection O repair. It can be dangerous for others drivers. When I get the report of the issue and receipt I will submit soon as possible. If any recall happen.
