2016 Hyundai Sonata Exterior lighting Problems

I was driving at night and my passenger headlights went out. About 2 years prior the same thing happened but it was the driver side headlight that went out. It was $1100 to get the driver side replaced and now here i am having to pay the same amount to replace the passenger side headlights. It was not a simple replacing the bulb. Something inside went broke causing the dealership to have to install a whole new headlight set.

When I lift the switch to turn on the right turn signal, the high beam headlights flash on and off. It switches from auto to on then back to auto. I'm not moving the switch front to back, only up and down.

I am having electrical issues with my 2016 Hyundai Sonata plus the other recalls. It started as issues with the lights on the driver side. I have replaced several bulbs and the entire light even and still have issues with the lights working properly. Now the issue is the battery, alternator or the starter. The starter had to be replaced as I was advised by Hyundai dealership when my engine had to be replaced, per recall. I had to purchase a starter, that was three times the amount at the dealership because the one that is manufactured in the auto stores is not correct, so it should not be the starter as it is only 1 to 2 years old. I have had the alternator replaced as well as 2 batteries and I’m still having issues. It cut off completely while driving on more than 1 occasion. There was no warning, no power steering, gear lock, no lights & no power so I could not move and almost had a major accident. It is definitely a safety hazard even after the repairs, it has happened again! My vehicle is currently not working because the new battery will not hold a charge and they both have been replaced. I’ve been having other electronic type issues with this vehicle. My information center has not worked for the past 8 months or so! I reported this to Hyundai and they agreed that it could be a part of a previous recall, and advised me to go to the dealership to have it repaired. The dealership refuses because they don’t have required information to show it as a Current recall and want to charge me half the price of a new car to repair. I am not the only one experience this as my research has led me to several other Hyundai owners experiencing the same issues. It is not fair that they cannot be corrected as these are things that are none of consumer fault & should have been high demands to proper repair or recall being a major safety issue as it can cause a horrific accident! Shame on Hyundai for putting their Hyundai customers at risk & through so much chaos!

The headlight setting changes on its own, it will change when using the blinker or it'll just change on its own. By change I mean the headlights turn off. Even if it's set to auto, they still go completely off. My bulbs don't need to be replaced. It's been happening for a few months now. I can't recall a specific date

Hello, I have reached out to Modesto Hyundai and consumer affairs since May of 2022. I have been shunned and told nothing is wrong. The message below was sent last year in May. I was turned away because I could not afford the diagnostic even though it was covered under a past warranty recall. I had to complain. A few months later I came up with the money and was told I was given the wrong information the first time. They kept the car for a week,, drove only 30 miles and said it was the battery. I recently had a oil change done at Hyundai in February 2023. They failed to mention the oil everywhere and said everything was fine. The engine stalls on a daily bases. The 2 prior oil changes one said they thought oil was leaking but didn't know from where the other said something was wrong with the oil pan. Also you can smell gas in the cab and the head and tail lights have been replaced 3x each in the last few months. "I have gotten no where with the Hyundai dealership here in my town. I was told I'd have to pay for a diagnostic to see if something is wrong before the vehicle could be checked to see if the engine is failing. I believe this car is a lemon and has stalled on several occasions. I recently had an oil change and was told their diagnostic came out clear yet the engine still acts up and will stall while driving. Will it take for my car to stall on railroad tracks and be hit by a train and killed before Hyundai fixes the issue? Women and children die in in faulty cars because no one would listen. A mechanic told me his friend had the same exact car down to the year and had the same issues and Hyundai said it was infact a recall and they replaced the vehicle. Did Hyundai make it right because he was a man? Is this something I should just look for an attorney for? Please help as I know something is seriously wrong with this car. I was told that Hyundais are safe cars yet I have never felt more unsafe in a vehicle." Thank you for your time. Hoping for the best.

Since the previous recall associated with the turn signal sometimes signaling in the wrong direction, I have noticed for months that when driving at night when the turn signal is on in either direction the lights function will start moving from on to auto to off causing the lights to turn off when signaling. This is very dangerous especially at night.

While driving at night, when I engage my turn signal to make a turn and my headlights go off. The headlights stay off until I play with the turn signal leaver moving it up, down, forward, and backward until the headlights come back on. I see this as a major safety issue. Driving a night without headlights impairs my ability to see and for other vehicles to see me. A search on the internet displays many websites discussing this issue for my year, make and model of car. Local Hyundai said there is no recall. There was no warning lamps, messages or other symptoms presenting on this issue. It appears there is a malfunction in the turn signal switch. This has been occurring for over a month.

The first is the drivers side headlight not properly projecting light. The light projected a shadow across the center of the light preventing proper illumination in front of my vehicle. This is causing a safety issue. Brought car to dealer who confirmed that the left headlight was deformed preventing proper projection of the light. This deformity was not covered nor are there any recalls even though numerous people reported the same issue. Am working on privately replacing them both. The second was the return tensioner not properly retracting the seatbelt back in. This was not covered by the dealer but it’sa safety issue where the system may fail.

Head lights. Not working. It's not the bulb or fuse. This is a safety issue. It looks like it's an issue with most make, model and year. My family's safety was put a risk drive when the lights when out. No to Q 3 No to Q 4 No warning intel i could see the road anymore then warning lights came. For the suspension the tire shop says there's an issue with suspension due to manufact Airbag Sensor warning light. Right side window doesn't go down also. If you get your hand in the window it doesn't go back down for safety

Recently purchased vehicle. Did not test drive at night or we never would have purchased. While driving at night, the low beams cast a black, unlit area in front of the vehicle. It's so bad that anyone crossing the street in front of vehicle would not be seen. It is incredibly dangerous, yet the dealer says the lights are set to manufacturers specifications. This is a serious safety issue. It has already caused us quite a few close calls with people and items in the roadway. Please help, as we cannot afford to trade it in, and although the dealer admits its a serious safety problem, there's nothing they can do.

Somehow, either by design or manufacturing defect, a part in the headlamp assembly melts and causes a gap in the illumination of the lights while driving. Technicians have said that this is a progressive issue, rather than some sudden onset, and multiple people have said they've never experienced this before but are having this issue with the Hyundai Sonata.

While driving at night, the low beams on the vehicle cast a very dark shadow approximately 30-40 feet in front of the car. While traveling, it us very noticeable and downright dangerous. If someone or something is in front of the vehicle, it would be hit. We have seen numerous complaints about this on the internet while searching for dilutions to the problem. Dealer says its within Hyundai specifications, however they have seen the problem and agree its very dangerous. Car was just purchased used, however we did not test drive it at night. It is so noticeable and dangerous that we try not to drive the vehicle at night.

My blinker switch that has the light controls on it as well is not working properly! The lights would be set to Auto, and it started randomly switching while driving at night or day on and off, at night when it's dark it just would randomly shut off and sometimes I wouldn't realize until someone lets me know. It could be very dangerous as other people may not see me if my lights are shut off without me knowing it. It sometimes flickers on and off as well, when I use the blinker stick to turn lanes. So something is wrong with the stick as when it's touched that's when it would flicker.

When headlights switch is in the auto position and you use the right turn signal the headlights go off then come back on. I've had this car for 4 years and noticed this a lot. Left signal is starting to do the same. Very dangerous especially when I do a lot of traveling on interstates. I think this needs to be addressed immediately
