The deflector partially detached in the front, and interferes with the glass of the sunroof when closing. This happened while driving down the highway.

Car was in motion at about 75mph on the highway when it jerked really hard then lost all power, making it a very unsafe situation for not only my family but also other drivers. The lights on the dashboard went all crazy and it hasn't started since that happened, car was towed to a dealership where they are stating it's a recall on the ECM.

My car was broken into on 3/3/2019, not only did my alarm not go off when the window was smashed when I set my alarm on the car and opened the door from the inside the car did not go off. The police officer stated that this is a hazard especially on a newer model vehicle. The police officer even tested out the alarm while they were here and it did not go off.

On October 26th my husband was driving myself and our 2 children when all of a sudden we went from going 45 miles an hour to stopping and then even after the gas pedal was pushed all the way to the floor we we were going approx 5 miles am hour. Our engine light came on and aftet approx 5 to 10 min we found a place to pull over as there were no pulloffs readily available. Aftet we pulled off the road we shut the car off for a few minutes and restarted the car and were able to make it home. The engine ligjt was still on but power and speed were restored. We called our Hyundai dealer on fri morning and they said to bring it down on Monday. The car sat all weekend and was not driven due ro fear of it happening again. I did however start the car on Friday and engine light was still on. We brought the car down mon at 9am. The engine light was now off but the Hyundai mechanic said even if the light was off a code would still be in the system. We received a call around 3pm saying they could not find anything wrong but even they did not under why no code at all showed up. They are keeping the car until Friday to keep starying and driving it to see if something happens. Mu husband did report the issue to Hyundai and they said they will investigate. If this were to happen again with someone driving behind us it could be a very serious accident. Very nervous and scared something can happen especially driving my yound children around.
While I was entering the freeway trying to merge in the traffic using left signal and depending on my car lane change assistance that failed to detect the car on my left blind zone, forced me to turn away from the car to the right side caused body damage to my car passenger side due to the street guard rails. The lane change assistance failed to detect cars many times, I will take the car to the dealer.

My 2016 Hyundai Sonata misfire sometimes at starting. Here is a little description. Today June 28 2016 I started my vehicle and noticed it was running a little harder making an unusual sound as I engaged the reverse the vehicle started rolling back slowly and checking like it was going to stall and stop. It all sounds like the vehicle has misfired and is running rough. I immediately stopped the engine and started one more time and this time the vehicle started immediately. This same issue has happened about a month ago as I was living the library.
Dual air conditioning does not operate correctly. Dealers explanation is that is was designed that way and since "it is operating as designed", there is nothing they can do. I filed a formal complaint with Hyundai and have asked them to verify that this "design" will not create a fire or electrical shortage. Hyundai Consumer Affairs case#: 10086770 (3/24/17). After several unsatisfactory conversations, I was given a supervisor named ally. Ally was polite and assured me he wanted to get some resolution. He called back once to assure me he was still checking into it. On April 21, 2017, I received a call from a female who identified herself as ally from Hyundai. I said that was strange, I have been talking to a male named ally. She said, "I told them this wasn't going to work." I asked her to have the real ally call me on April 24. I never heard back so I followed up Tuesday with an email, but still have heard nothing. I just want some verification that there is no way this design flaw will cause a fire or any other problem. I want to know how long the warranty will stay in place since I have reported this problem.
While the vehicle is in motion and when I hit the brake. A click noise is always coming when we hit the brake till the end. Always happening observing from past 2 months. The other problem is when we hit the brake and and hold the shift knob it is making tick tick noise. Always happens when I showed to the mechanic they are saying it is normal because they have to do it for free of charge. Hyundai gives warranty but the dealers neglect to do. I am getting a mileage of average 10 miles if I even maintain a speed of 45-50 mph. If I put 14 gallons of gas I get hardly 225 miles and I have no problems with the car and I change the oil before the service interval.
