Engine died on the interstate at 65 mph, then the dash lights started going crazy. Shortly followed by smoke coming from the engine compartment. I opened the hood and could see a short casing the fire which I could not put out with my extinguisher.

At 1st, my tail light went out on my passenger side of the car. I tired to fix the problem with replacing the bulb. This went on for several times. It got to the point that the bulb wouldn-??t fix the problem. I then replaced the wiring harness. That worked for a day or two then the light was back out. I even went back to the dealership and had then replace the wiring harness, I was thinking perhaps I had a defected one, still to no avail. I then paid the $170 diagnostic fee so the dealership could find the problem. Well, I was told the problem was beyond the tail light and it was more than likely needed to be traced throughout my car. The job was gonna be too time consuming and costly for that particular dealership and ultimately my money was returned. Throughout this crazy process I had contacted the Hyundai corporate office to report the problem and was dismissed. So, here-??s the bigger picture. Once I started researching this problem more and more people were having the same problems as I. The light bulbs in the tail lights was burning so hot that it would burn out the bulb, the wires and the housing causing many people to replace bulbs and in some cases the whole unit. This what happened to the driver side of my car. The entire housing and wiring was not good and the whole thing had to be replaced. Hyundai has some serious electrical defects with the year and model of my car. They don-??t want even acknowledge that there is a problem. Honestly, one of the employees explained to me how this was a known problem and how the company tried to fix it by making the socket thicker with the hopes of the bulb not burning out. This employee knew the the wiring harness was changed before to the new one the original one because of the color of it. So, clearly, it did not solve the problem. Now that my electrical issues existent beyond the tail light means my car could be at risk of fire at anytime. Last thing, my high beams don-??t work now also.

Having to replace headlights and brake lates every month, now rear passenger side light is completely out and will not come on after changing all bulbs and fuses, see this as a major safety issue, there are many complaints about this same issue and Hyundai is ignoring this safety issue

- Minot , ND, USA

I started my 2014 Hyundai Sonata Hybrid and proceeded out of the garage. Almost immediately out of the garage, a loud high alarm went off and the dashboard read "Electric Motor Warning - Safely pull over and do not drive". My vehicle simultaneously lost any ability to accelerate and slowly tried to get the vehicle into a parking spot in our apartment's driveway. This was not the first time this has happened. This same thing happened earlier this year and required a recall service that I was told to be fixed after being without a vehicle for 3 months!

Last night 9/5/22 I went to change out my brake light on driver side which should have been very simple when next thing I know I-??m having a very hard time twisting the socket to remove from housing because it had fused the plastic together from burning. Idk if you think it-??s normal but to me that-??s a very susceptible spot for a car fire. Anyways I decided to check passenger side and again same issue. The last pic was of the passenger side burnt end of the brake light.

Head Lights Go Out Completely at Highway Speed Headlight dimmer switch fails to switch between high and low beam. Lights can go completely out with zero viability during nighttime driving conditions. Speed of vehicle seems not to be a factor in the headlamp failures. May also fail to dim from high-beam to low-beam in the instant of oncoming traffic. Causes a great deal of distraction to safe driving as attention of diverted to fiddling with the headlight/turn signal switch stalk. Lights have sometimes gone completely out (dark) at highway speed in congested traffic conditions. Has been an issue since I purchased the vehicle in 2015 with under 17,000 miles but the problem is getting progressively more frequent. I am concerned that in the future, I may not be able to get the head lamps to come back on, while I am at highway speed and no chance for a safe emergency exit of the roadway.

I drove a mile from my house and the vehicle stalled at a turn. The engine shut off. I tried to turn it back on and it did not. I have an electrical push button and it did not work. My passenger and I pushed the car out of the road into the back area of an HEB. We then opened the hood and the engine started smoking. I had called my boyfriend who then arrived. The engine continued to smoke and an HEB driver saw the incident. He came over with a fire extinguisher and sprayed it because they could see flames starting under the car. The fire department and police had been called. The car engine then went up in flames and my boyfriend used the fire extinguisher. The fire department arrived and went over to the car and cut the wires. Nothing on the car works. It has not been assessed because I only had collision insurance and my company would not come to assess it. They did tow it back to my house where it is sitting and not working. I can't even move it into neutral. There was not warning of this and I had driven the car to the airport (an hour away) and back five hours earlier that day and it seemed fine. The fire department said that if they need to be contacted they have a report on the incident.

We were driving and the engine just quit. We were able to safely get to the median. The minute the car was stopped we smelled something burning. We got the kids out of the car and to the other side of the road. We looked under the hood and could smell the burning but didn't see where it was coming from. Soon we were back on the side of the road waiting for our ride to pick us up. About 20 to 25 min later we saw smoke coming out of the hood. My husband called the fire dept and just as they arrived the whole thing lit on fire under the hood. The fire dept was able to put out the fire. Now we are waiting to have it appraised by our insurance company.

Hybrid System Warning! This is the second time I have received this issue. It seems like a big issue within these types of cars. The first time I took it to Hyundai and they said replace the transmission. I took it to my transmission guy and he just changed the alternator and it worked. Now today, I am getting the same error message, but all the answers online are completely different things. I called Hyundai again and they once again suggested to replace transmission. They are trying to rip people off. This car is a lemon.

Headlights turn off when applying it turn signal. Low beam headlights are not shining far enough down the road to be able to see.

Headlights will randomly flash off/on while driving. Using turn signals will also make the headlights (and some interior lighting) flicker off/on. Headlights were replaced, but problem still exists. This is a major safety issue for me as other drivers believe I'm flashing my lights intentionally, not to mention, driving at night and having your headlights turn off randomly isn't very safe. We feel very unsafe driving this vehicle after dark because of this issue. This problem started at approx. 70,000 miles. Took the vehicle to the dealer and was told the issue is a defective multi function switch and that others are having the same issue. However, but the dealer said this issue is only covered by the warranty up to 50K miles and I would have to pay to have this resolved. I contacted Hyundai Consumer Affair's and opened a complaint with them. I was assigned case number 18855023, but was told there isn't anything Hyundai could do and I would need to deal with my dealer to get this repaired out of warranty. From my research I've found that many other Sonata owners are experiencing this same issue and that some of the Hyundai Genesis line of vehicles also are experiencing these issues, but in response to these Genesis owners, Hyundai has extended the warranty of the multifunction switch assembly to 15 years with unlimited miles from the date of original retail delivery or date of first use (whichever occurs first). Why is Hyundai not addressing this same issue that exists on their other model lines"?" Hyundai needs to extend the warranty and repair this defective switch for ALL other Hyundai models. This is a very unsafe and potentially life threatening hazardous issue that needs to be address for all Hyundai customers and not just the Genesis owners.

As I was driving down the road, my light start flickering. Then immediately go out and wont come back on. No warning light came on. My light stating my trunk was open came on but my trunk was not open and the tire pressure light came on but normally it states which tire and that didn't happen either. Nothing was wrong with the tires either. I had them check.

The contact owns a 2014 Hyundai Sonata. The contact stated that while driving at 65 MPH at nighttime, the turn signal switch was engaged, and the headlights inadvertently turned off. There were no warning lights illuminated. The contact stated that he was able to turn on the high beams by engaging the high beam switch. The dealer was made aware of the failure but informed the contact that they would be able to diagnose the vehicle in four weeks. The dealer also advised the contact that the turn signal switch needed to be replaced. The contact also contacted a second unknown dealer who also advised the contact that the turn signal switch needed to be replaced; however, the earliest availability was in a couple of weeks. The contact stated that the failure had been reoccurring while driving. The vehicle was taken to an independent mechanic and the turn signal switch was replaced. The manufacturer was made aware of the failure but did not provide any assistance. A case was opened. The vehicle was repaired. The approximate failure mileage was 97,200.
