2016 Hyundai Sonata: headlights failing or too dim

Filed Jun 2, 2026 · Lights · SC

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.

Car is still driving good, but after I've had it for a little over a year now the first thing I noticed was my horn went out, then the headlights went out, then my temp gage is flashing and the engine light comes on & off. Certain dash lights come on & off. I just got an oil change. I've been taking my vehicles to Pep Boys for several years now. My last oil change on the Sanoto was the 3rd or 4th oil change . One of the reps told me that my car is now consuming oil. He said it's not leaking on the ground but something is causing the oil to burn. I don't know if you have a warranty on it but he suggested I take it to the dealership. Again I've only had it a little over a year. I'm financing the vehicle and have about 4 more years to go. HELP!

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.

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

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.

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.
