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.

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"

What seems to be random and without provocation, the car will sound a beeping alarm that only sounds on the interior, it will deactivate the accelerator (basically puts the car in neutral), and will display a warning message that reads "hybrid system warning! safely stop and do not drive. Check brake". no matter what speed the car is traveling at, it can undergo this problem. If brakes are applied during this issue, it will sound as if the brakes are grinding and are not functioning properly. The issue can only be resolved by putting the vehicle in park, turning off the vehicle, and restarting it. If this is done, the car is back to 'normal' function. It has certainly been a safety hazard as it has done it multiple times in bumper to bumper traffic while traveling at higher rates of speed, and the car stalls out in the middle of the freeway. The Hyundai service department has found no issue after running diagnostics, and says there is nothing that can be done to remedy the issue overall. I would estimate this exact issue has occurred approximately 20 times, periodically, over the last 6 months.

As I was driving my car one day my wheel suddenly became stiff, I was unable to steer. I almost hit two cars while driving, on my dash the wheel logo with an exclamation point came on and sleepy road icon as well. I almost lost my life that day, I went to an advanced auto part because I felt like it was a power steering problem, I bought power steering fluid only to find out that my car is electric power steering. I turned off my car and the icons went away, the next day it did the same thing out of nowhere but thankfully I was in a clear road. This defect has put a risk on my life and will to others, please recall this vehicle.

The check engine light illuminated intermittently at 92K miles, then the engine started making noises intermittently, and then the vehicle was slow to accelerate intermittently. The knock sensor software upgrade had previously been installed. The synthetic oil had been changed at 82K and 86K. South point Hyundai changed the oil, replaced the battery and turbocharger at 92381 miles. Around 93246 miles the intermittent engine noises and intermittent no acceleration and slow acceleration are back, and the check engine light is not illuminating. Returned my Sonata to South point Hyundai who reports the engine is bad, but there are no diagnostic error codes, and they are waiting to hear back from Hyundai on how to proceed. Hence, the knock sensor software update is not a corrective action for detecting engine failure, alerting drivers to engine failure. The knock sensor software update is not an effective screen for engine defects. The engine noises occur when the vehicle is stationary, in motion, on a city street, and on a highway.

"check charging system" warning message came on while driving on the highway at night 01/08/2021. Suddenly no power to the engine. The gas pedal wasn't working. Quickly I pull into the hard shoulder. The car failed to start the engine with the same error message. The car lost power shortly after. (the hazard light wasn't working. I contacted 911 for emergency assistance. Penndot truck shows up after an hour to cover the road. ( to prevent collisions.) I towed the car to a nearby dealer. Contacted by the dealer 3 days later. They said it was12V a battery issue and it's fixed. I went back to the dealer the next day to pick up the car. I paid $388 for replacing the battery. The car won't start with the same error message. I ran into the dealer asked for an explanation. The worse thing is the dealer never ran the diagnostic test for code or anything and assumed it's fixed. I demanded a refund. I made a few calls to check the status of service since then. No one has returned my call yet.

I was driving the vehicle on a highway going no more than 45 mph and all the lights came on and it shut completely off. I tried to get a jump but it still didn't do anything. There was no engine lights or anything on my dashboard besides eco. The car hasn't had any issues at all. For some strange reason my steering wheel been locking a lot.

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

While driving my Sonata an error appeared on my dashboard stating 'hybrid system warning! safely stop and do not drive. Check brakes." When this occurs the gas pedal goes to the floor and the brakes grinds my tires. U can hear a loud chiming like sound coming from the car. I'm reading this issue with a number of Sonata hybrid.

When driving at night my headlights some times flicker like from high beams to low. This is bad enough, but when they go completely out on 2 lane highways at midnight it is heart stopping. Have learned it might be multi function switch ( turn signal switch). To be repaired at my expense even though there has been hundreds of complaints for this issue. Rep from Hyundai told me he had never heard of this problem even as dealer mechanics says happens all the time.. maybe another class action would get their attention before some is killed.

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

While driving on the highway, apx 70mph, occasionally my 2014 Sonata gls will completely die. This has happened at least 10 times not in the last two months, always when the car is in motion usually at highway speeds. The dash lights all go black, radio cuts off, and engine dies, for apx 2-3 seconds, and then usually turns itself back on like it never died. Occasionally though the car will not turn itself back on. When it dies, the steering also becomes very stiff and the brakes are extremely hard to use. My car has only 112xxx miles and has always been serviced regularly. There has never been any check engine light on or any codes stored when checked. I've contacted Hyundai service center multiple times. Each time they tell me that they can't help me, there are no recalls and I should 'check my battery connections'. I have, they are all fine. I'm very concerned for the safety of myself and my three children. Three mechanics now have checked out the car and they can't seem to find any problems.

The contact owns a 2014 Hyundai Sonata. The contact stated that start-up there was an abnormal sound coming from the engine. The contact also stated that the display intermittently failed to operate while using the back-up camera. The vehicle was taken to gossett Hyundai South (2660 mt moriah rd, memphis, tn 38115) and the contact was informed that the vehicle would be repaired under warranty. Several days later the contact was informed that the vehicle was not subjected to a warranty repair and that the vehicle would have to be repaired out of pocket. The vehicle was then taken to wolfchase Hyundai (7727 us-64, memphis, tn 38133) and the information was confirmed. The vehicle was not repaired. The contact received notification of NHTSA campaign number: 20V121000 (fuel system, gasoline) however, the part to do the recall repair was unavailable. The contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair. The contact also stated that there was an abnormal buzzing sound coming from the exhaust system. The manufacturer was not made aware of the failures. The approximate failure mileage was 45,000. VIN tool confirms parts not available.
