I bought this sonata one month ago. Driving down [XXX] in bonita springs Fla the car shut down. No noise all dash lights came on I got to a safe place. Sat in the parking lot of fresh market for at least 30 minutes went to start it and nothing happened. No crank nothing. AAA came towed it to my house. The filling day I checked the battery it is good. So had it towed to Scotty’s automotive. They called me Friday morning and said the motor was locked up. According to Carfax the car was at brand ton Hyundai in May of 25. I called after I bought the car Carfax said they found the alignment was off. I called to see if they did the alignment they said they did not do it. The wholesale it. My thinking is they did service it according to Carfax report and knew there was signs something and wholesale it. I did not buy it from Brandon Hyundai I bought it from a guy in Leigh acres Fla.

The vehicle is used as a commuter car, and driven primarily on NJ Turnpike at high speed. Over a two month period, on four occasions, the engine has shut off. All dash lights came on, and all power assist controls failed. Managed to get to shoulder of road, and after a few minutes, car would restart and run properly. The fourth time it happened, as I coasted onto shoulder, the car restarted by itself. Took car to dealer for diagnosis and repair and was told there were no codes and it "could be" any number of parts not working properly, but no actual diagnosis. Was charged $160 dollars, and I took vehicle home. But when I looked over the invoice, I found the description of problem was not what I had told service rep, so went back to talk to service manager. He told me to bring it back in and he would have it rechecked. Was told they drove car 35 miles a day but it never stalled. However, invoice shows same mileage went brought in and sent out. Again, they said they could find no codes, so they could not diagnose any problem. I went and picked vehicle up, but I drove through the dealer's parking lot to leave, I saw the engine service light was now illuminated, and returned the car to the service department. Was told they would check it out, and I went home. After three weeks, I called to find out status of car. Was informed they had yet to look at it, but would do so shortly. A week later I was told problem was a bad VCM Motor Assembly, and I was charged 788.70 dollars, to replace a part that apparently fine, when I dropped the vehicle off. Read numerous posts online by owners reporting this same engine shutting-off problem, since 2016. But no one has stated a definitive cause, or repair, by dealers. As to whether that was the cause of the engine shutting off, I will have to see.

Vehicle suddenly lost power while in operation. Vehicle was in motion approaching an intersection. When left turn indicator was activated, all lights on the instrument panel illuminated, the engine shut off, and power steering was lost all while the Vehicle was in motion approaching a intersection with stop sign. Vehicle was able to stop before entering the intersection, but would not start again and we were stranded in the middle of the road. Electrical systems appeared to be working. Battery and alternator are functioning normally. After Vehicle sat for 20min, it then was able to start and moved out of the road to a safe location. Vehicle was towed to mechanic that confirmed Battery health and alternator functioning. Vehicle was then taken to dealership for recall 210 safety repair. Dealership service unable to determine cause for loss of power while Vehicle in operation. No explanation, offer of additional service, or remedy has been offered despite requests. I do not feel it is safe to operate this vehicle in the absence of information related to the sudden loss of power during normal operation. Had this occurred in another setting with more traffic or less room for safely coasting to a stop, serious injury or worse could have resulted. The vehicle is still eligible for the 10yr 100k mile powertrain warranty and I am the original owner. We do not feel we can safely operate this vehicle and need guidance on how to proceed with pursuing a remedy to the situation from the vehicle manufacturer.

Car has been consuming an excessive amount of oil (1-2 quarts per week). While driving down the highway the oil pressure light came on and the engine started clicking and knocking. The engine died and all the dash lights came on. The car was coasted to the side of the road and towed into a local mechanic. The engine had seized and presumably dumped all the oil at the time of the engine failure since the engine had no oil when diagnostic was run. Car was taken to Hyundai dealership and is awaiting diagnostic and repair.

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.

All dashboard lights are turning on. The car loses power steering. The car will at times not turn on. This happened a few months after I purchased the car. Hyundai can't seem to find the problem. The problem eventually goes away by itself for a few months and reappears again. We had the fuel sensor and battery replaced. They said my alternator and starter is still good. The car never stalled during driving only looses power steering which can be dangerous while driving. We noticed when we adjust the steering wheel up and down, it cleared the issue for a few months as well. I believe 2015 hyundai sonatas are experiencing electrical issues. I read online other owners having the same issue.

I was about the change lane and I felt that the steering wheel is harder to turn than usual. I was turning right. I immediately pulled over to the nearest street and parked. I left the car running. After a minute the steering wheel was locked I couldn't move it. Then, all the lights on the dashboard turned off and the AC stopped. Many warning lights turned on. I turned off the car and I could not turn it on again. It was towed to the dealership (it is under warranty) and they said it was the alternator and the battery. They replaced the alternator and the battery and said it was fine. I took the car back, paid for battery and after 20miles I felt again some glitches in the steering. I immediately pulled over to the nearest parking lot and I could not turn the steering wheel anymore. The car was on but the steering was locked. I turned off the car and again, I could not start it. I am really afraid because if this happened on the freeway and I was in the middle lane, I would not be able to turn my steering wheel. I would not know what to do. What is worse, the official dealer 'fixed it' but the same issue arose after 20 miles again. What if I was to go on a trip? I am really worried about what is going on with the steering. And I paid for the battery which in the end may not be a problem at all. I feel ripped off and the car is only 44,400miles and it is 3 yrs old.
