Break lighting assembly and wiring harness melts during normal operation. Unable to replace bulbs because lighting assembly melts to the socket or the socket melts over the bulb metal base. This causes break lights to fail without the owner knowing. Which could result in accident due to no break lights also the traction control system can be effected by this short by shorting out the break light relay.
2014 Hyundai Sonata electrical complaints
Page 5 of 6: complaints 101 to 130 of 135, newest first, as owners wrote them.
The software update per hyundais "953" service campaign, when activated, reduces engine performance which could lead to accidents (due to insufficient acceleration, etc.). I had the recent engine software update per hyundai's 953 campaign. On 3/22/19, I exited a highway and slowed down prior to merging onto the next road. I needed to accelerate, however my engine bogged and hesitated significantly. As such, another car quickly approaching had to break heavily to avoid a collision with my car. I looked down and observed my engine light flashing. I took the car in to action hyundai (millville, nj), and they stated that the newly installed software had detected issues with my engine and automatically placed my engine in this low-power mode. I have since learned that I will be receiving a warranty engine replacement.

The vehicle was towed to an independent mechanic who diagnosed that the starter was faulty and needed to be replaced. The vehicle was repaired, but the check engine warning indicator remained illuminated. The manufacturer and local dealer (rodgers hyundai, 2700 michigan ave, chicago, il) were notified of the failure. The failure mileage was 108,000.
Esc light and hard braking issue(ABS module?): ESC light turns on and the car applies hard brakes without any action from the driver while driving. This happens while driving on a straight road or freeway (not while turning). Sometimes, the ESC light doesn't turn on but the brakes still get applied while in motion without any action from driver. It has happened 5 times so far - 2 of those while driving at more than 60mph on freeway but was fortunate to pull to the shoulder safely. One instance of the problem showed up when the car was stationary but with engine running (at a parking lot). As you could see, this is a safety issue putting us in danger without any prior indication or no known resolution. I have taken it to the local hyundai dealer service center but they cannot find the root cause yet. They have already tried replacing brake switch but that didn't help. I have filed a case with hyundai directly too and waiting to hear from them.
I have had my alternator and battery replaced within the last month and my car is cutting off while I'm driving it. The lights on the dashboard come on the radio powers off and the wheel starts jerking back and forth and it cuts off or begins to cut off and corrects itself. I was driving in the city during these incidents and the car was either turning or pulling off. Once on the highway it cut off while in motion.
The left rear light where I place the bulb is burned out. The housing of where the bulb goes has to be replaced. Also, both headlights where I replace the bulb has burned out and needs to be replaced. There is a shortage in the wiring in the rear lights.
Engine began to slow down...I pulled off the freeway safely as the car beeped and displayed a warning: 'hybrid drive failure. Place car in p. Do not drive' they should also add, call a wrecker, in all fairness. Waiting on hyundai's answer. After tractoon issues in ice and snow in addition to this...when I get this car back, she's a goner! I need a real vehicle.
The back lights are going out extremely to often. I have to change them out at least once a month and when changing them I notice that the bulb is black, almost like they are burning out. When I replace on side, a week or two later I have to change the other side. It seems to be a wiring issue.
Tail light bulbs melted into socket. Had to get both replaced. Fire hazard and a defect in design.
When signaling to turn left the headlights would go off and back on. It happened when the car was parked, or while driving on city streets
Hyundai has ongoing problems with turn signal stalk switch assembly, which causes intermittent blinking of dashboard lights and headlamps even while cris in motion. This is a dangerous problem that has been noted in multiple models across multiple years. Search any owner forum group and there will be multiple mentions of this problem.
Headlamps and taillights continues to go out been up to the dealership over 7x this year.

Fuel door actuator is faulty. Fuel door will not release when release button is pushed inside the cabin, nor open via emergency release cord in trunk.
When I stopped my car and put in park I turned the key in the ignition to the lock/off position but the key would not turn to lock/off go in the off position. So, the key was stuck in the ignition. I turned the car on and shifted to drive than back to park and turned the car off to remove the key however it was still stuck. I did this several times because I had the same problem two week prior and this method worked. I was by a locksmith that I could was to unhook the battery until I could take it to the dealership.

When I turn the left turning signal on, the front lights flickers and switch between high and low beams. Sometimes they turn off. Also the interior dash lights flickers and turn brighter. I also have to replace front and back light bulbs 3 or 4 times in less than a year. I went online and these problems seemed to be a recurrent complain.
Every three to five days when push to start vehicle it will not turn on. All lights/electronics come on but the vehicle just will not start. When towed to the dealer or tow driver arrives the car starts again. Have had the battery tested and tested bad, replaced but the problem continues. Hyundai says "cannot duplicate the problem" and sends me on my way with no resolution. Now dealer as well as hyundai regional office refuse to answer the phone or return any of my messages. Has happened at least if not more than 15 times.

While driving multiple indicator lights on the dash came on, (brake, ABS, tractions control, steering, seat belt, air bag and check engine lights.) t highway speed the transmission shifted into 1st gear and I was forced to exit the road immediately. I safely came to a stop and shut the vehicle off. I then restarted it and then I was able to safely get home. I then called aaa and had the car towed to my mechanic. My mechanic found that they could not communicate with most modules/computers that are in the car. After hours of testing, they discovered that the back up camera was corrupting the computer data lines and essentially shutting down crucial modules in the vehicle. Once the camera was removed from the car, the vehicle operations returned to normal. Please advise hyundai of this issue, so other motorists can be spared this frightening experience. I will provide the invoice for repair and the failed part, which I have in my possession, if you need. Please contact me for further information.

On three occasions my car would not start. After the second time it failed, I brought it in. Hyundai service department could not find anything wrong with it after hooking it up to the machine. No codes showed on the system check. They said they checked the battery. They said it could be the brake sensor, which was changed from a recall, so they said I have a new one, they would just adjust it and hopefully would fix the problem. Three days later on a saturday morning, the car would not start again. I brought it back in. They kept my car from 06/20 - 06/30 and could not find or reproduce the same problem.
