While going home on highway 95 at approximately 70 mph. The vehicle stalled almost causing many accidents. Thank goodness I steered it on the shoulder and it will not restart I had to call for a Tow. This was the 3rd time this happened. The first time was approximately a month in 2015 after my purchase it stalled on the highway. Again, in 2017 it once again stalled on the highway while I was driving. The dealership has told me on all 2 previous occasions that they had fixed the problem and it wasn't going to happen again.

This is the second week and my car is still in the dealership which they are saying they don't know what the problem is smh.

While driving on 395 in heavy traffic headed home I hit the accelerator and the car slowed down. The cars behind me almost hit me and swerved to prevent a accident pile up. I was horrified, shaking and crying because I knew I was about to be slammed from the rear. I hit the gas again and I heard a clinking noise. I knew I would not make it home. All of the lights in the dash came on. I pulled to a safe place (downtown near the Capital) and had it towed to the dealer. It was the first exit I could take. 3 weeks later, the dealer is saying it was an engine issue. My car is still covered under warranty but it appears as if they are trying to avoid replacing it. A rep called from the dealership asking about oil and I told him there was no warning lights that ever came on the dash to indicate anything was wrong; everything happened at once.

This 2015 Hyundai Sonata LTD ([XXX]) falsely indicates CEL/emissions light. When the vehicle is started and the temperature is appx. 20 or lower, the indicator immediately displays. It is solid and does not blink. This happened on -3- days this week, over approximately 7 of -9- total ignitions in that time. Various forums show the same issue. Hyundai must recall this because it is either a false warning or else is a component within their control with which they failed to manufacture safely (thus contributing to the problem(s) and CEL).

Sonata started having problems with less than 50,000 total miles. The accelerator is flawed and the vehicle cannot keep speed when traveling uphill or get to speed efficiently. The vehicle jerks for a few seconds when pressing the gas and the engine revs but the vehicle does not accelerate like it should. This has almost caused me to have accidents multiple times when pulling out into traffic. The check engine light came on when this started occurring and has been on ever since. I'm having the hyundai dealership take a look at the vehicle and see if there is anything that can be done.
