This is a common problem I see in these cars. The taillights melt and melt the housing causing a fire hazard and collision hazard due to no brake lights

Vehicle stalls/dies while driving. It stalled 2 times but when I pulled over, it would start right away. While trying to make it home, it stalled for a third time and while pulling over it started smoking so bad I thought the vehicle was going to catch on fire. Vehicle had to be towed. There is an engine recall for this vehicle but dealer is giving me the runaround. Very disappointed with how Hyundai has handled the incident that almost caused an accident that could off been deadly.

I have been having to constantly replace my tail and brake lights since October of 2018. I believe there is some type of short with the sockets. One moment the lights are on, the next the are not. Or, one side is working and the next moment, the other side is not. I see this when using the fob to unlock the doors or someone tells me the lights are out. I have had to physically adjust the bulb socket for the light to come on.

My son was using my car and noticed that it was starting without applying the brake. I have always pressed the brake before pushing the start button, otherwise, the care would not start. After having this brought to my attention, I tried it and it did the same thing....started without applying the brake.

The first time I went out to start my vehicle and it wouldn't start while in my driveway. I called Hyundai freehold and they said there 'may be' a problem with the engine but they wouldn't know until they brought it in. (really, even with the massive recalls across the nation? okay.) they would not pay for the tow. They would reimburse me after the fact. I played dumb and had it towed to them but reported it to Hyundai corporate. Then Hyundai of freehold admitted there was a recall on my vehicle and they would give me a new engine. The second time I was coming out of the college from a night class and it wouldn't start. I called them the next morning and they said the same thing (we won't pay for the tow we will reimburse you). They knew by the second time around that I had purchased a third party warranty so either way they wouldn't be stuck with the bill. I had it towed by the third party and paid the difference as the first time. This time they said it was the starter. (hmmm, okay). Now here I am a few months later. And I go out to my car and the car isn't starting (again). Should I bother to call them and ask them if they will pay for the tow this time" what's the difference right as long as I'm not paying anything but he difference after third party payment you ask? it's the principle! also, what happened when my third party agreement runs out and these knuckleheads are still saying (we have to see if it's something we did!?! or worse yet, something happens while I'm out with my two year old?! they are clearly doing this to other people I checked their yelp page I'm not the only victim. Please help"! I can't afford to wait until my third party warranty is up for them to fix the problem or give me a vehicle of the same value mins the problems. It's literally been one thing after another since I bought the car. And forget about asking for a loaner!

The contact owns a 2012 Hyundai Sonata. The contact stated that the rear tail lights had an internal electrical short and contained rust and corrosion. Also, the sockets melted on both sides of the rear tail lights. The rear passenger side light had to be removed to prevent the middle rear brake light from remaining illuminated. The rear driver's side tail light was operable, but eventually shorted out as well. The contact ordered replacement tail lights three times, but the failure recurred each time. In addition, the contact heard a loud noise concerning the fuel system. When turning the steering wheel in either direction, the contact heard an abnormal noise intermittently. The vehicle was included in NHTSA campaign numbers: 18V137000 (seat belts and air bags) and 18V934000 (engine, fuel system, gasoline); however, the contact did not receive any notifications. Mcgrath city Hyundai (6750 w grand ave, Chicago, il 60707, (773) 889-9090) was contacted, but had not diagnosed or repaired the vehicle. The manufacturer was notified of the failures.

Well I bought the car a few years back. I learned about a few recalls on the car and took the vehicle in. They fixed one issue, while they said the engine was fine. 2 years pass and I was driving on the freeway. Note there where no signs of the engine having trouble. Just passed smog. Had the oil changed, the air filters and intake filters changed. The car makes this noise like a rattle noise. I turn off my music and was listening to the noise. The car seemed like it was losing power while I was driving and accelerating was declining. All of a sudden che K engine light comes on. Not even a moment later the engine turns off. I was scared. On the freeway and my steering locked up couldn't use the brake and wheel was useless. I was able to get the car restarted for a moment to get to the side of the freeway and down to a safe area but then the car stopped again and wouldn't restart. Has it towed home. Not only was this highly unsafe, it put my life my kids life and other drivers at risk in getting into a severe accident. I was lucky. But the experience was something else. Also the seat belts dont always lock in after the first try. U have to buckle 3 times before it stays
