The (mil) malfunction indicator light came on and my car just suddenly stopped running when I pulled up to a stop sign, when I braked for stop sign to make a left turn, while driving, leaving walmart shopping center. I checked the NHTSA website and found that the (mil)malfunction indicator light is under investigation

The contact owns a 2014 Hyundai Sonata. Ever since the vehicle was purchased brand new, the contact experienced issues with the air conditioner blowing the wrong temperature during the seasons. The brake lights were also malfunctioning. The vehicle was taken to ray brandt Hyundai (1700 westbank expy, harvey, la 70058, (504) 684-8039), but they could not duplicate the failures and stated that the VIN was not included in a recall. The contact took his vehicle back to the dealer numerous times, but the air conditioner failure continued. For example, the defroster would blow out cold air in the winter. The manufacturer stated that there were no failures with the vehicle since the dealer could not duplicate the failures. The failure mileage was 500.

The problem started with external light bulbs going out. Had to replace 4 in the matter of couple months. Smell of burning rubber (thought it was gas), radio restarting automatically. One day was driving down a road, all the sensors started flickering, the vehicle lost power, engine shut off, came to a stop. I managed to restart the vehicle in couple minutes and drive it the nearest shop. Happened at 78 K miles. The shop said they cannot fix this problem, had to take it the dealership where it is now. Will take a week to fix and well over a thousand dollars in cost. Absolutely unacceptable electrical issue in such a young vehicle, Hyundai needs to take responsibility and have a recall. Looks like its a very common issue in this model.

Driving in light rain on normal pavement St louis county. Approached stop sign at end of steep hill. Applied brakes lightly and well in advance but car was not stopping. Realized that engine had stopped so nothing was working. Car began shaking violently as if brakes were trying to grab. Finally came to a stop in the middle of intersection - fortunately nobody was in front of us are attempting to cross intersection in other direction. Car was completely dead. Tried to restart but nothing. Had to move car so tried to start again - starter did not crank at all, but suddenly engine was running as if it had never stopped and all power was restored. Drove immediately to dealer thinking it was something to do with engine recall. Was able to get to the dealership about 5 miles away with no incident. After 3 days of being at dealer we were told that something in the brake fluid "module" had broken lose and brake fluid leaked into wire harness causing extreme corrosion. They believe the engine never actually stopped running, but rather the electrical signal was momentarily interrupted due to the corrosion. It was going to be a $5000 fix. We did not have car repaired. Dealership said they would send it to auction. This car must to be pulled off the road as it is a hazard to anyone who purchases it, even "as is". reported to Consumer Affairs at Hyundai on 11/6/19. Spoke to a representative 11/14/19 and was told car would be taken out of service. I am reporting here to insure that it is indeed taken out of service. We could have been killed or seriously injured. Wife drives about 35 miles per day and it could have easily happened while she was driving to work.

Brake lights keep blowing out. I have replaced individually 2 times, and both together 2 times in 2019. I know I am not purchasing off-market or used or faulty light bulbs. There must be something wrong with the vehicle. The most recent replacement of both bulbs was Oct. 20, 2019.

Taillights constantly burn out and work inconsistently. My passenger side taillight currently does not work after the entire taillight connector/wiring harness has been changed due to the bulb burning and melting the socket. The fact that the light gets hot enough to melt thus piece is a fire hazard. Additionally my ESC light goes on for days and then suddenly goes off. I don't believe it possesses a safety issue due to possible unpredictable malfunctioning.

Vehicle stalls when accelerator after coming to a stop. Try giving gas it want move or it will coast very slow. After 30-60 seconds it will pickup speed. Sometimes it will not allow to reverse or go up inclines. I've shaken to two different dealerships and one mechanic shop. Was told that if car is not stalling at the time problem can't be diagnosed. I've been on major highways and this has happened which is very scary. When it started happening it would be in a rare occasion now after at least one year it is much more often. Now I'm noticing after driving it for two hours continuous the battery dies down and the ac goes out. I'll turn it off which charges the battery but does not help the stall issue. It started at around 80,000 miles I am at 120,000 now

In 2018 I started periodically to smell an electrical burning odor while driving my car. My driver's side headlamp went out. I replaced it on Saturday with replacement part from autozone. Sunday that bulb went out. Took to dealership 4/24/18, they replaced it-hasn't gone out again. Smelled burning again. Received police ticket for driver's side taillight out. Took to dealership 6/26/18, explained smell. Verified wiring assy/socket was burnt up & bulb melted to socket. Called Hyundai cs because they wanted me to pay for repair, explained periodic burning smell. Hyundai replaced harness & bulb, no charge to me. In June & July 2019, I had been told by unhappy motorists, you have no rear lights &/or brake lights. Took to dealership 7/19/19 explained burning smell. Was told passenger brake light burnt out. It was replaced, I was charged $44.84. They said nothing about smell. Not being happy with the service dept not addressing the smell, I called Hyundai cs again. A case was opened. Took car to different dealership for diagnostic per Hyundai case. They only did the rearend, tech said they had known issues on this. Both sides were found to have burnt up wiring assemblies again that need to be replaced. Tech reported to me that the last tech at the other shop would have seen this issue at the time they replaced the bulb, if they replaced it! Hyundai gave me 2 options; they pay parts & labor-no warranty on either, or they pay parts & I pay labor for 12 month/12,000 mile warranty. I am paying labor for warranty. There are numerous reports online regarding this same issue. I will live in fear of my car burning up with/without me in it. Or god forbid being in an accident for rear lighting failure which could result in injury or death to myself and/or others. This issue needs to be fixed by Hyundai and a recall & extended warranty time granted due to manufacturing problems!

Takata recall the vehicle is always stationary when I am unable to put it in drive from the park position. I am unable to put my driver's side window up, the interior lights went out, my tail/brake/turn signal all went out the same day. All fuses have been checked, they are fine. The car was sitting in my driveway overnight and the next morning I went to turn the wipers on to clean the window of bird poop and they wouldn't work followed by the clock saying 1:01 and it was around 8:30am. Then I noticed everything else, the rear lights were called out to me by another driver on the main road by my house

Takata recall, the brake light & housing for the brake light burns & gets hot immediately after pressing the brake, whether the car is off or on. The brake light also needs to be changed too often...seems dangerous, there's a defect. I took my other car (same exact model & year) to Ontario Hyundai about 4 or 5 years ago & they changed the housing, stating there had been issues & now I'm experiencing the same issue & it's not showing on the recall list.

The led tail lights are known to fail. The entire circuit board fries itself out. The tail lights flicker and pulse when on, and the brake light will do the same when it is pressed.

I and many others have had to replace rear brake bulbs, and rear running lights consecutively over the past 7 months and they burn out to quickly and are a serious fire hazard. This needs to be considered as a recall because of the hazard with of the harness burning. Fix it!

On 4/19/2019, I was driving my car at 60 mph on freeway and suddenly car's speed dropped to 20 mph with check engine light (mil) blinking. Also car was hesitating and wasn't going beyond 20 mph after that. It went into limp mode / low power mode. I got my car towed to Hyundai's dealership on 4/20/2019. I was informed that there was an issue with the knock sensor harness and it has been replaced under campaign T3G. I picked up my car from the dealership on 4/23/2019 but my car is still having knocking sound, car is hesitating and I got the engine light (mil) back up again on the very next day I.e. 4/24/2019. My car is at the same dealership since than for the repair and they are waiting for the parts from the Hyundai factory. I also contacted Hyundai Consumer Affairs center for this and case#: 15700612 has been created for this complain.

I have had my car about a year now and I have had to replace the rear light bulbs 3-4 times because they keep burning out. It will eventually lead to a fire with this hazard. The bulb housing is burnt inside and the bulbs were stuck in there from being burnt. Also, the headlights are so dim and short out. I have to use my lights on bright and they still are dim. There needs to be a recall for this for the 2014 Hyundai Sonata before it causes a fire. I am only commenting because I read the exact same thing as my car has been doing and figured if enough people complained then they would realize this is hazardous. This has happened about 3-4 times and I am picking the date below for the last incident. Also, it only has a yes or no under was there a fire. I would have picked almost due to the burnt housing. I just wanted to point that out

Purchased a Hyundai Sonata 2014 Nov 2016. Are very serious issues with interior and especially with exterior lighting, brakes lights, rear lights. Break lighting assembly and wiring harness melts and burns to a black crisp, bulbs burst due to severe overheating during "normal operation" of the vehicle. Safety and fire hazard with rear tail light lap assembly, bulb burns extremely hot right through plastic housing unit. Unable to replace bulbs because lighting assembly melts to the socket's core and the socket melts over the bulb metal base. Expect extreme damage prohibiting replacement of any bulbs. After being pulled over repeatedly, informed exterior lights were even after just changing them.. light bulbs burn hot rapidly, melt to the socket make it unable to get any replacement light bulbs to work because entire unit is then damaged, burnt and melted. Bulb will not fit because plastic unit has melted from circular to inward. Lights fail without the owner ever knowing until its too late. I've been parked at mall police officer informed me light was out, driving on highway pulled over 7 times given warning, repair orders due to lights out, pulled over on side street, road and lights just go out on highway. By the time bulb goes out its burned the entire unit through wiring, anything touching or around it. Change lights every 2, 3 weeks. When changing them I notice damage worsening, metal and bulb are burnt to a crisp. When I replace on side, a week or two later I have to change the other side. Creating a trickle affect. Once one goes out. Another goes out and so fourth. You literally have to replace the entire housing unit which is very expensive. Same repeats.. tried to replace bulb with a halogen bulb instead and the base and bulb also burned.. under assumption that doesn't burn hot. Did not work. During severe rain pre-existing issues only worsen and magnify..

I am having to replace tail lights and head light bulbs frequently. If not mistaken I am changing a bulb out every month on this vehicle. I had to purchase new tail light assemblies due to the bulb melted the plastic housing and the new bulb will not lock in. I also have an issue with the headlights going out and turning back on. I was pulled over 3 weeks ago, due to having a head light out, but when the office walked to the front of the vehicle he apologized and said it was back on. This is not the first time I have been stopped due to either my head lights or tail lights being out and magically turning back on. On going electrical problem.
