Headlights and taillights constantly burning out. Taillights have melted sockets on both driver and passenger side and it seems the fuses are burning for anything powering the exterior lights. This is a safety hazard from not being seen on the road by other vehicles to a potential fire hazard.

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.

When driving at night headlights, and all lights goes off.(I do not drive much after dark, but this needs to be addressed). It has happened a few times this past year, thought it was me, yet my daughter used the car and she had it happened 4 or 5 times.Sometimes it happens when you use directional lights. No warning when it happens, which is very dangerous.There is only less than 68,000 miles. Supposed to be under warranty 100,000 miles or 10 years, yet I am told I have to pay $150 to do diagnostic which may not be solving the problem which is not fair. Looking online there are many complaints of this on this year and model. Asked the manufacturer when will they do a recall" After someone gets killed"

Driving in the early AM darkness went to turn on my bights and my headlights and every other light went out leaving me moving at 60+ miles an hour in complete darkness on a highway. Headlights also flickering intermittently and at times when I try use my turn signal. Baffled at how this has not been recalled. This is a deadly manufacturer defect.

Tail lights continually kept burning out. Eventually, after a few installs, tht last one melted requiring they full assembly to be replaced. The first side went out on the right a couple of years prior, this year the left side did the same thing. The smell of burning was noticed, and found the cause from the tail light.

My engine was replaced last year because of a recall. Since then progressively I've been noticing my head lights will turn themselves on and off at will. At times also the interior dash lights will do the same. Where I will have to jiggle the nob to turn them back on again. If I happened to run over a bump in the road the flickers worsen. With everything shutting down early last year I wasn't driving often when the sun was down but now that I am this issue isn't resolving itself.

While driving and parked the headlights will turn off when the left blinker is used. Headlights will also flicker and then the high beams will turn on randomly. Other times the lights will completely turn off inside and outside the car. Since this started my battery has drained on 3 separate occasions requiring roadside assistance.

When my brake light bulb went out we tried to change it. It was melted into socket. Took to dealer they said $250 for each side. Both sides had melted in. You dont just replace the socket U replace wires and all. $250 each side everytime they go out. I have since learned this happens in all Hyundai models and years. Why are they not recalled?

My headlights keep going very dimmed and brake lights consistently burning out in my car. I am replacing them every couple of months. This has been going on over a year.

This is a major issue thousands are having with this model 2014 Sonata. When using the blinker, it causes the headlights to completely shut off while driving. Soon as the blinker turns off it kills the headlights. Extremely dangerous and Hyundai seems to be ignoring this issue and pretending they're not hearing of it often. I've had to pull over many times until the lights come back on. Seems to be an issue in the steering column. Cruise control also decides when it wants to work. Sometimes on startup it works, sometimes it doesn't. I believe it has to do when the car is started. Something odd electrically with these cars. But the blinker/headlight issue is causing wrecks. This is wildly dangerous

Drivers side brake light bulb exploded, and melted into the socket. I was advised that you cannot replace just the socket and Hyundai is quoting $400 for the entire wiring harness. This is a fire hazard and causes an additional safety hazard with the loss of the brake light

The tail lights are failing on my Hyundai. Hyundai is very well aware of this issue and there is several online accounts of it from other owners. The tail lights flicker on and off rapidly like a hazard light. This occurs during the daytime with the daytime running lights and most especially during the night while operating the vehicle. Hyundai has been advised of the issue and refused to replace them despite the safety hazard, citing the age and mileage of my car. However, at the same time the installed a new engine in the same car with the same age and mileage.
