When I go uphill it shakes. When I'm driving it will cut out. We have replaces plugs 2X in 6 months a sensor. It burns through a quart of oil every 400 miles.

- Pryor, OK, USA

While driving the car at highway speeds, the car and engine start to shake. The shaking impacts the steering wheel and drivability of the car. The car loses any acceleration power and the check engine light comes on. The issue usually lasts 1-2 minutes. Afterwards, the shaking slows down and stops, then the check engine light turns off. When I took the car back to the dealership, they said the engine needed to be replaced. 5 months later we are the same issue is happening.

I purchased my 2016 Sonata used from hertz. About 4 months after the purchase I was hearing rattling sporadically from the engine and consuming oil. At the present time I add 1 quart for after 400 miles of driving. If I put in high text gas the rattling doesn't happen as often but this engine doesn't require high test gas. Regardless I'm still consuming much to much oil. I read that others have had engines seizing and some daught on fire. This seems to be a real danger and I feel its a problem that should be resolved by Hyundai.

My vehicle engine is stalling yet my VIN is not on the list and it should be added to the list because my engine is coughing and I would like the issue resolved before it shuts down on me.

- Charlotte, NC, USA

2016 Sonata with 103,000 mile. Increased oil consumption. Regular full synthetic oil changes have been followed. The engine burns out oil well before oil change is due. Oil lamp flickers. Mechanic states oils is burning up and released through exhaust therefore no leaks detected. 2nd issue: P2122 check engine code. Diagnostics reveals pedal acceleration sensor faulty. Part was $202. Not sure if this is misdiagnosed and related to sluggish engine due to oil consumption.

I was on the highway driving and as I begin to accelerate the car felt as if it was about to stall out. When I came to a stop sign and made a complete stop as I accelerated to drive the car did the same thing as if it wanted to stall out. Now when I'm driving I can't go over 60 mph and any time I come to a complete stop and try to accelerate the car acts as if it wants to stall out so I have to take off slowly then take my foot off the gas pedal and put it back on as if is having trouble getting gas to the engine. I took it to my mechanic and it read code P 1326. Now my car is in safety mode

Hello I purchased a 2016 Hyundai Sonata 4/8/2020 with 110,743 miles on it with now 116,000. About a month ago my check engine light came on with no symptoms to the naked eye. Maybe a week later I could feel the difference in the speed control the air intake seemed very sluggish it won't take off from the line it will drag before it decides to pick up speed. Now the issue is that this is a common problem with these specific cars with no recall on them. This is an expensive fix that I should not be responsible for. Code P200 intake manifold.. it's not safe to drive a vehicle that you cannot control its initial speed...

Vehicle has persistent issue with hybrid system. Check engine light will come on, and after some period of time, error message "check hybrid system. Turn off engine." Will appear. Car then loses power from combustion engine, and can only operate on electric. Requires pulling the car over, turning the car off, then turning the car back on, which will allow power to the combustion engine to be temporarily restored, but the check engine light will remain on. The car is unsafe to drive in this state until looked at by the dealer. The diagnostic code is P2600. This vehicle has been taken in for service by the same dealer for the same issue four times, and is now scheduled for a fifth. The dealer has been able to fix the issue three times for a period of about 7-12 months after replacing the water pump, but issue continues to recur. Dates of issues and mileage below: March 1, 2018: 27,451 October 15, 2018: 39,820 June 3, 2019: 47,380 July 26, 2020: 60,500

- 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.

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.

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