Brake lights not working. Checked fuses and bulbs, neither are the issue.
Engine light is blinking and put safety of my family in danger. I called the close Huyndai dealer also I have a case number. However, it takes forever for them to answer. I only have this car. I am driver and this how I make living. I have no choice in driving this recall vehicle and kill my self and my family. No body care!
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.
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.
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!!!!
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.
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 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.
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.
Back light panel had to be replaced because light keep blowing. Engine is burning oil and have to put oil in often
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.
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.
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.
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.
Tail light melting replacement of the assembly required.
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.
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.
The contact owns a 2014 Hyundai Sonata. The contact stated that the electrical system had failed to operate as needed both inside and outside of the vehicle. The contact stated that the taillights had failed to illuminate upon depression of the brake pedal, while the interior lights would flicker. Additionally, the headlights would also flicker while in operation without warning. Additionally, the contact stated that an abnormal clanking sound was coming from the vehicle without warning while making left turns. The contact had taken the vehicle to the dealer where they informed her that there were no recalls on the vehicle. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 63,000.
WHEN USING THE LEFT TURN SIGNAL THE HEADLIGHTS TURN OFF
