Hello. I am reaching out regarding concern as to the malfunction of my brake lights. I currently own two 2012 Hyundai Sonata vehicles. The lightbulbs in both vehicles go out within days of being replaced. I was advised by a Hyundai technician that the casing of where the light bulbs is inserted was "melted" and needed to be replaced. I was also advised that my car was not covered under warranty and was not covered under a recall. In my research of this malfunction, I have found that this is not a individualized issue or concern that is isolated to my vehicles. In addition to causing a potential risk of a accident, I am very concerned regarding the potential of a fire due to the "melting" of the casing.

My Hyundai Sonata 2012 recently experienced engine seizure on a 5 lane highway in NJ garden state parkway at 70 mph without any warning what so ever.car was checked for this recall year ago and supposedly software was installed to notify if engine was to fail. There was no warning! dealer confirmed the engine died and is covered under the recall. I also had mentioned concern about the noise under the car. They replaced the engine & serpentine belt and told me to come back in 3 days as it was too early to do the inspection. When I got the car back the noise was still under the car, the tire light came on, back door lock stopped working and ac stopped working I called back and they told me $1500 worth of work to pass inspection. 3 days earlier they said the car was good to pass. Including Continental tires that Hyundai horrible suspension ruined at 16K miles(tire warranty 70K miles) and both sway bars and sway bar link. Which means I could have rolled the car at any curve.axles were changed twice on this car as they told me " manufactory faulty" axles they put on and other suspension parts. Tires were rotated and aligned by them! if that's not good enough person working on my car damaged both of my front doors when letting the car off the lift.then the dealer tried to cover up the damage and sign me the car back! car has some serious electrical issues with interior/exterior. Lights melting, bulbs burning and now the car doors locks. Better yet new recall says if you had your engine replaced you are in a danger of the fire.how am I supposed to trust this "certified dealer" ? + the other 8 recalls and class actions about this car- Hyundai needs to be forced to buy back these all of these cars. Not only is that not safe for me its also not safe for other drivers! I've also been without my car for about a month at this point.

Multiple parts have been replaced on my front end from what mechanics thought were the problem but my wheel still sticks/pull to the left while driving even after multiple front end work and alignments. Also, I've replaced head lights, tail lights, breaks and reverse lights numerous times because something keeps blowing them. When I press the volume button on the steering it changes the screen on the radio. I'm assuming it's something with wiring malfunctioning. The cruise control on the wheel doesn't always work as well

I have purchased my car in 2014. Since I have had this vehicle, I noticed that my brake lights were going out more than the norm (for other vehicles). I have received countless of tickets of the electrical issue that the 2012-2014 Hyundai Sonata owners have yet to get resolved/addressed by Hyundai. I have had several of my police friends and other current/former Hyundai Sonata owners to tell me that they have pulled many people over with the same year/make/model for brake lights. This electrical issue is hazardous for not only me and my child, but any other individuals who share the road with me. The most recent incident was the last and final straw for me. I was driving when another individual informed me that my brake light was out yet again. I went to the autozone to attempt to change my light bulb just to discover that the electrical mechanism that holds the bulb in place is broken. It appeared that the light bulb went through a mild burst of flames. To have this happen, especially as a mother, on the same side as my child sits is unacceptable! I'm sure that if you conduct your own research with police about vehicles being pulled over, you will surely see that the number one reason was because of a broken brake light. I hope to hear from someone soon.

Consumer stated every time I fill up my gas tank on my Sonata the dash board indicates that I have zero gas available this caused my check engine to come on its is a concern because I believe it can cause and accident on the road or the car can catch on fire this situation happens all the time when the car is in motion and when I start it as well.

Tail lights, head lights and break lights keep melting the bulb to the socket leaving me with no break lights and not knowing until someone pulls up N yells at me. It also has caused me to get pulled over numerous times. Advanced auto parts told me their corporate office told them they can not replace them bc it is a known Hyundai issue and it's dangerous that's why their bulbs keep going out of stock for this car. Lights inside the car some times flicker on and off and twice the entire inside of my car went pitch black causing me to have to pull over on the side of the road. I have over 200 pics of other Hyundai with the same issue and I have told Hyundai about it and called corporate about it numerous times. I attached a collage with some places I go N randomly always see others w the saaaame light out or no lights at all!! obviously this is a manufactures defect! I should not have to be forced to pay $400/ per light to fix a socket!!! this has been going on since 2016 and I'm just about tired of it bc it seems to keep getting worse!!!

The vehicle does not start as it doesn't recognize the key fob. My daughters and wife have been stranded on different occasions as they were not able to start the car. Something is wrong with the electrical as the engine does not recognize the key. I am scared to take the car on long trips as this happens frequently and it can take up to 20 attempts before the engine starts. Please help!!

My airbag light came on randomly one night and will not go off, it will flicker on and off but eventually just stays on. This happened a few nights ago. I noticed it once I parked at home. This morning when I crunk the car, it was on and then went off and came on every time I turned my steering wheel until it just stayed on for the remainder of my drive. Also the interior lights stay on unless I have them turned off (if they are set to come on with 'door open' they stay on indefinitely)
