While driving in traffic car began to jerk and lose speed though the engine was running. The car stopped in the middle of moving traffic. Transmission fluid spilled out profusely. Transmission was replaced but started to slip again the same day I picked it up after new (remanufactured) transmission was installed by the Hyundai dealer. Prior to this transmission issue, the alternator in my car failed while driving in the middle of moving traffic. This complete transmission failure occurred shortly after a new engine was installed because the original engine seized and failed prior. Alternator was replaced. The newly installed alternator failed again. A new alternator was once again installed. I am now having similar electrical problems yet again and there is a current concern that the vehicle may possibly stop suddenly and hazardously again while in motion.

I pulled into a parking spot and noticed nothing out of the ordinary with my vehicle. When I was stepping away from my car and pushed the lock button there was no clicking sound. I continued into the building and returned to my car a few minutes later and it would not start. All of the lights would come on, but the brake locked up and the car would not start. I attempted to charge the battery which did not work. I unhooked the battery cables for a period of time to reset the lock system and possibly unlock the starting system, which did not work either. It has only been two weeks since I took this vehicle into the dealership to have the computer system updated due to engine failure issues in other vehicles. I purchased this vehicle less than a year ago and it does not show from what I can tell a recall. However I was instructed by the dealership to have the car towed into them so they can check to see if it is engine failure or a number of recall issues that I have not been aware of.

Started having electrical issues, 1: when you use the button to roll up front passenger window or put the car in reverse the electric trunk opener will pop the trunk open. 2: trouble with low voltage to the waste gate accurater sensor that controls the turbocharger unit. 3: number 2 did not start until two other codes showed up on my check engine light. Those two codes are P0011 & P0014. This electrical issue seems to be a major problem with this car. Me and my wife are on disability and can not afford the cost of a dealership to continue to try to fix it when they don't even seem to know what the problem is.

Arriving at busy intersect when accelerators and brakes ceased to work all dash lights began flashing and I was fortunate enough for light to be green and was able to coast to a stop at shoulder through intersection w flashers and horn blowing ! I restarted car and pulled into a local business w a clunking noise!! was told by my mechanic who has regularly serviced this vehicle that it was the engine ! why brake/acceleration not working ?? I was told he's had 3 other Sonatas in this month that 'just burned up all the oil ' without a light on or anything. I could have been on S busy highway and killed in addition to risk to others.

While driving on two lane highway vehicle shut down without warning. The car smelled of burning plastic and smoke was coming from passenger side under hood. Car was towed to dealer and motor was replaced thru recall. On 8/20 I was scheduled to pick up and was notified that the main wiring harness had melted badly and that it would not be covered. I filed case #11538113 with Hyundai corporate on 8/20, citing that it appeared to be related to the motor seizing, and/or a safety defect. I was denied assistance on 9/20 and contacted the dealership to begin work at my costs. The car is still at the dealership as they are stating Hyundai cannot release the wiring harness. Research on why brought me to similar compaints the appear to warrant a recall.

Car would not start so replaced the battery. The next day the battery was dead again. Took it to a mechanic they stated it was a short in the brake light switch. Also, while driving the car and taking off from a stop sign, red light it would not accelerate while pressing the pedal an seemed like transmission was slipping. While driving down the interstate at 70mph the car would lose acceleration dropping my speed to 40 mph. Causing me to almost cause an accident with cars behind me having to slam on their brakes.

The rear tail lights burn out, the housing unit or lenses melt and the lights do not work. This has happened several times, replacement of light bulbs are continuous and the lights seem to have some sort of shortage. They work sometimes and sometimes they do not.

- Tampa, FL, USA

I have had to replace brake light bulb every month for the last 3 years. They have gotten hot enough to melt the hole you insert them into and then cannot be taken out because the heat made the hole smaller

On June 8th, 2018 my husband was driving down interstate 85 in charlotte nc going about 60 mph when the vehicle stalled. He coasted the car to the side of the interstate. He turned the vehicle off then tried to restart it and nothing happen and power was dead in the car. Then he saw smoke coming from under the hood. The doors won't open so he had to climb out though the sunroof to safety. He opened the hood and the engine was inflamed with fire. He called the fire department, they came and put the fire out. The reason I'm filing this compliant is because he could have been seriously hurtor killed if the sunroof was close. Hyundai has no explanation for why this is happening and my vehowas total lost. We also have pictures and a video. I can't upload the video so if someone contacts me I will email it.

First issue occurred in my job's parking lot, as I tried to crank my car it made a roaring start and didn't want to stay on. Cut the car off, checked oil. There was barely any on the stick (just got an oil change on 09/21/18 at Hyundai dealership). Added 2 qts had mom drive to dealership per serviceman request. They changed my oil and informed my mom of an ongoing issue. Well get off headed home, on regular county road headlights flashed off and on alone with radio console. Pulled over lights stayed on, but I notice taillight that has been replaced multiple times over the last couple months was out again. Tried to replace it and the wire was hot and bulb wouldn't come out. So, I decided to wait till I get home. But now I'm waiting on the side of the road because my engine light is

My car was in motion when headlights started dimming then car lost power and was begigging to stop..kept depressing gas pedal and car then started moving again. I was traveling on a main road in left lane when this happened which could have been a major accident. Also have numerous brake light bulbs replaced and key fob will not be recognized to start car but car will start when keyfob inserted into charger in miiddle console. Key fob will work to open and lock door but not for starting car.

Key fob in 2012 Hyundai Sonatas not recognized and don't allow you to start up your car using the push/start button; also, doors won't unlock with fob and manually have to be entered using actual key. Seems like some programming to the fob has been lost; dashboard would turn on and say"key not in vehicle" or "insert key" when depressing the push/start button. Apparently, dealerships are aware of the problem, but may not actually report it and treat as something else only after numerous other repairs. Youtube videos of these issues as I've described are available. Vehicle is stationery when this happens; then it would work and then stop again in a few days. Changed batteries in both fobs and still the same issue. Originally starting happening a week prior to 9/27/2018.

I was driving my 2012 hyundia Sonata down the road, and all of a sudden, the whole car shut off. This caused the steering wheel and the brakes to fail. Fortunately, I was able to make it to the side of the road, and I smelled smoke. At first, I thought the engine was overheating, so I opened the hood to see what was going on. I saw a ball of fire, and quickly grabbed my 4 year old and 10 year old out of the car. By the time I got them out of the car, the whole engine bay engulfed in flames. After telling my story, I have had multiple people reach out to me with similar stories.

- Dover, FL, USA

While driving car on rt 50 West bound towards the bay bridge, an engine popping noise occurred, then fumes starting coming from vents. Pull car over while getting out flames were already coming from the engine. Within minutes the whole car was engulfed in flames. No time to retrieve any items inside the car. The md transportation authority police were on the seen and called fire dept. Fire department said it was an electrical based on sparks as they were putting out the fire. Hyundai investigated the car remains and could not determine any cause.car pictures are to large of a file to submit

- Arnold, MD, USA

Around 60,000 miles, my driver's side brake light harness melted and had to be replaced. Around 80,000 miles, my passenger brake light harness melted and had to be replaced. Around the same time, 80,000 miles, my automatic door lock master switch began failing. I'm wondering if there's an electrical flaw causing these problems. Perhaps the writing doesn't hold up in hot climates, I live in a desert where the car is subject to temperature up to 140F as it is parked in direct sunlight. I notice more malfunction with locks on extremely hot days.
