2014 Hyundai Sonata Exterior Lighting

Brake lights not working. Checked fuses and bulbs, neither are the issue.

The turn signal stem assembly randomly begins failing after several years (approx 5 years). Issues will be noticed while driving in the dark. When turn signal is applied in both directions, occasionally headlights will turn off or flash causing interior lighting to change to brighter daylight settings at the same time. This can be disorienting for the driver as well as others on the road. To remedy the incorrect lighting situation, the driver needs to jiggle the turn signal stem assembly and normal lighting will resume. At subsequent turns, the entire situation repeats itself. Other drivers may believe they are being alerted to something or potentially angered, causing misunderstandings or altercations on the road. My original turn signal stem assembly was replaced after about 5 years due to this series of events. Now, after approximately 5 more years, the exact same symptoms have begun again with the authentic Hyundai OEM replacement parts.

Right brake light assembly melting around lightbulb and right brake light not working due to the burn. I went to multiple used auto parts store to try and buy the right brake assembly and noted multiple cars from 2011-2014 had the same issue.

When head lights are in Auto mode occasionally all of the exterior and interior lights go out. Including dash lights. I cannot make it repeat at will so nothing ever gets done with it. There is no warning when it happens just complete darkness inside and out. Obviously I can’t see where I’m going when it happens they typically come back on after a few seconds. This has been happening for over 1 year. I don’t use the lights in auto anymore, it doesn’t happen when it’s not in auto.

The lighting system on the front and back lights, tail lights and brake lights has shortages and melts the housings that the bulbs go in. I have had two of these cars with the same identical problem.It’s very dangerous because the tail lights work whenever and me as the driver can’t see behind me nor the person driving behind me will know that I’m stopping. I can’t drive my vehicles at all at this present time and have made an appointment the dealership, Hyundai and filed a complaint as well. Something has to be done quickly to put this on the recall list because it’s very dangerous for myself and others on the national highways. I see a lot of the same identical cars as mines with the same exact issues. It’s ridiculous!!!!

The contact owns a 2014 Hyundai Sonata. The contact stated that on various occasions, the brake lights and turning signals failed to illuminate as designed. The contact stated that she replaced the bulbs seven times; however, the failure recurred. The vehicle was taken to a local dealer, where it was diagnosed that the taillight wiring harness assembly had melted and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 20,000.

A family member alerted me that my passenger side brake light was out. I went and purchased a replacement bulb to change the light. As soon as I went to pull the old bulb out I noticed the housing the bulb sits in was warped, cracked, and discolored like it had been burned. The old bulb can't even be pulled out without having to break the bulb because the plastic is so warped. Being unable to change the brake light is a hazard because I can't alert other drivers when I am stopping. Also if the bulb got hot enough to burn the housing on the tail light it could have potentially started a fire. There weren't any warning lights that a brake light was out.

Headlights need to be replaced every three months. Brake lights turnt out and melted the plastic around it. Had to replace the entire light unit. Now, the breaklight doesnt work at all. Even after replacing the entire light unit and bulbs.

Vehicle headlights turn off / on while driving

The headlights and signal lights go out at least twice a year without warning which happens at night and or when raining. The dealership says they know that's why they keep plenty in stock. I've been dealing with this for 6 years afraid to drive at night or in rain because I never know when they will blow. I'm sure this can be verified by the amount of bulbs being replaced and sold. Help. This has to be a defect. Thank you.

Exterior lighting out (fuses)-- head, brake, tail, signal

Brake / parking lights on both sides have burned out more than 2 dozen times. This started when the car was less than 2 years old at about 20,000 miles and continues. Reported to dealer several times. Most recently on 4/22/2022. We were told they have no solution to correcting the problem.

The contact owns a 2014 Hyundai Sonata. The contact stated that while attempting to replace the rear taillight blubs, she had noticed that the bulbs had melted into the connectors which results in loss of rear taillight use. The vehicle was taken to a local dealer where it was diagnosed with needing a taillight wiring harness replaced but was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 89,000.

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.

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.

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.

Break light harness was burning around the socket. Caught on time could of caused a fire and serious injury to me and my children. This should be recalled as it is known to be an issue with most of this model vehicle.

My brake light went out and it must of caused a shirt cause it then melt a portion of the plastic from the light assembly.

WHEN MY BRAKE LIGHT BULB WENT OUT WE TRIED TO CHANGE IT. IT WAS MELTED INTO SOCKET. TOOK TO DEALER THEY SAID 250.00 FOR EACH SIDE. BOTH SIDES HAD MELTED IN. YOU DONT JUST REPLACE THE SOCKET U REPLACE WIRES AND ALL. 250.00 EACH SIDE EVERYTIME THEY GO OUT. I HAVE SINCE LEARNED THIS HAPPENS IN ALL HYUNDAI MODELS AND YEARS. WHY ARE THEY NOT RECALLED?

Tail light melting replacement of the assembly required.

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.

Break lights continue to burn out. In the 5 yrs I've had the vehicle this is a constant issue. I've taken the vehicle to Balise Hyundai replacing the Bulbs multiple times and replaced one Harness. Today both break lights had to have a full assembly replacement, including harness and the bulbs melted the plastic. The passenger break light even exploded that's how overheated it became. There have been no indication when these lights burn out. I've always had a stranger, neighbor, family or friend alert me that one of my lights were out. 4/26/21 a stranger driving behind pulled up next to me to alert me my tail lights were out. Not knowing break lights out is a safety hazard whether driving on street or highway. The back window has an additional light that has continued to work. In the last 3 years my driving was reduced more than 60% as I relocated to work from home. The vehicle was serviced today 6/2/21 at Hiley Hyundai who performed the most recent inspection and diagnostic on the vehicle, as well as performed the repairs.

I AM CONSTANTLY HAVING TO HAVE MY BRAKE LIGHTS AND HEAD LIGHTS REPLACED. THEY ARE BLOWING EVERY 2-3 MONTHS. I HAVE HAD A MECHANIC LOOK AT THE WIRING AND THERE SEEMS TO BE NO CORROSION. I AM UNSURE WHY I AM REPLACING BULBS EVERY FEW MONTHS

THE HEADLAMP SWITCH APPEARS TO HAVE A MALFUNCTION. TOUCHING IT TO TURN ON THE BLINKER OR THE BRIGHT LIGHTS CAN CAUSE THE HEADLIGHTS AND DASHBOARD LIGHTS TO FLICKER.

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.
