I was driving my vehicle on the highway when it started knocking and would not accelerate above 55mph. I drove straight to the dealership, where I found out the car had ran out of oil. I drive the vehicle for work and it has regular oil changes and maintenance. However, when the vehicle ran out of oil, it did not notify that there were any issues with the engine or oil level. The cars 'check engine' light did not indicate the engine was having issues, after the knocking started. Nor did it indicate it was low or out of oil. The car just worked one day and did not the next. The dealership and manufacturer assumed some liability, but not all. The vehicle should have notified the driver, that it was low on oil. It's extremely unsafe for a vehicle to run out of oil during operation. I also subscribe to a remote vehicle monitoring system and I pay monthly to the manufacturer. That system also did not know that the vehicle was low or out of oil. It did not indicate any issues until the shop repairs the engine.

- Maurepas, LA, USA

My car has slowly been consuming more and more oil as its life goes on. I currently have 80,000 miles on it and I can't even go a whole 3,000 miles without an oil change or adding more oil because it goes through it all. Something needs done about it as this is not normal for a car.

After a period of driving, which is random at best, the check engine light will appear and the vehicle will start to shudder and lose its ability to accelerate. This happens when the vehicle is in motion and happens both on the freeway at high speeds, as well as on city streets in low speeds. The only way to get this to stop is try and get to a safe space of the road and turn off the vehicle. It is very scary and dangerous especially in southern California freeway traffic and in mountain passes as you lose the ability to maintain speed in the middle of traffic. This could very easily cause an accident. This has happened to me on 7 different occasions over the past 2 months at random times.

I stopped for gas and when I attempted to start car an alert came across my screen saying car has a hev issue and check engine light. I would have to wait for 15 to 20 minutes for my car to start again. I was assuming it was bad gas but mechanic confirmed that it wasn't a bad gas issue. I went to the dealership and they said it's a potential electric issue that my warranty does not cover. I had yet even exceed mileage above 70000 miles. I believe this is an issue that is an inconvenience to me and other drivers because it is starting to happen more frequently. This could be a father for anyone in a urgent situation and need to be able to activate the car to leave immediately. Thank you for your consideration.

Used car with 86,000 miles on it. On the 90th after buying car from used car dealership, a rattling noise became apparent. When I took the car to a mechanic, it was determined the engine was blown. They said that it was seized and if I had been on the freeway, it could've been catastrophic. After some research, I found a proposal for the settlement of a class action lawsuit including many Hyundai and Kia cars. The settlement included all Hyundai Sonata vehicles years 2011-2018 and some 2019 vehicles. My car is clearly one of the cars affected. I am seeking help from the NHTSA so that Hyundai can take responsibility for their careless mistakes that have already resulted in many accidents and car fires. A Hyundai dealership will be looking at my car on January, 6th 2020. I'm anticipating them trying to brush this under the rug and blaming the issues on me despite having the car for only 90 days after purchase along with the abundant knowledge of Hyundai and Kia knowingly using faulty engines. I need your help to ensure they fix their mistakes at no cost to me and other owners. These mistakes need to be resolved swiftly so that no more consumers suffer unnecessary harm and financial burden for the mistakes Hyundai and Kia knowingly made.

Driving to airport in car. Just pulled in to freeway after stopping at store 45 mins into drive. My 3016 Sonata hybrid limited started making a knocking sound. My boyfriend who is a mechanic recognized it immediatly. Then suddenly engine made loud noise and parts and oil flew all over behind us from underneath car. He managed to get it off road without us getting hit.waited 4 hours for tow that was covered by warranties I purchased. Hyundai tried to state that only 2 people could ride in tow truck. So one person (there were 2 adults and a child) would have to wait in middle of nowhere while other 2 went the hour back home with tow truck and then came the hour back. There wasn't a gas station or anything around. The car is in shop waiting to see what warranty says about it needing a new engine. All maintenance was done and was in Hyundai shop 5 weeks prior with ABS unit needing replaced. There was no warning light or engine light that alerted us to a possible issue.

It burns through about 2.5 quarts of oil every oil change and Hyundai says that normal... that's far from normal.
