    There is a recall on my 2012 Hyundai Sonata motor. Which has caused the motor to lock up. Hyundai is refusing to fix the recall issue. Both dealership and customer care have stated that the motor locked up due to the recall but they are refusing to fix the issue, stating it is my fault. My car had 130k miles on it. The dealership has had my car for 2 months and they never contact me regarding the progress on my car, I have had to contact them.

    It all started with the electronic system. Both of my brake lights burned, leaving huge holes in the back of my brake light bracket. Replace the whole brake assembly on both brake light fixtures, then now my horn is not working—nothing to do with the relay or fuse.

    I was driving and DoorDashing for money when all of a sudden there was a weird knocking noise, causing all of the lights on my dash to turn on. I had just taken my car in for an oil change 2 days prior to an independent service center. This was the first time this situation occurred. I had never dealt with it before. I went to make a left to get out of the road and a burning smell started to occur and my entire car died in the turning lane. I was stuck in the lane for about an hour until a tow truck came and towed me to Huffines Hyundai Plano. While there they told me I had a lot of recalls and they would take care of them. About a week later they called me to tell me that my entire engine had seized up and failed and my recall was denied due to a software update campaign back in 2015 that I did not do. I have been to multiple Hyundai Dealerships since 2015 and was never informed of the severity of this recall, nor was I told if I didn't get such a software update that if my engine did indeed fail they would deny fixing their mistake to begin with. I had no idea of the important of this software update and really don't understand how it comes down on me that metal shards potentially were left in the engine, causing to dislodge and ruin my engine. It was incredibly sudden and I have only put 50,000 miles on the car in 7 years since owning it. The dealership also kept bringing up my warranty as if that had anything to do with this recall that is out for the engine.

    As I was driving on the highway, my car engine stalled and all the interior dashboard lights came on. I was unable to accelerate although all other features of my car worked (steering, brakes, radio, bluetooth, etc...). I was barely able to get off the highway safely as the highway I was on had no shoulder that was safely accessible. Luckily, I was in the far right lane already which allowed me to exit the highway. I was just barely able to exit the highway and move to the middle and far right lane of the service road before my car came to a complete stop. I attempted to turn my car off and back on without success. At this point, I could start to smell burning of something and knew I needed to exit the car immediately, however, I was unable to do so due to traffic on the driver side of my car. I noticed smoke coming from my engine which prompted to me to jump out of the car without continuing to pay attention to the traffic that was passing me. I called 911 to alert them of my car impeding traffic, potentially causing another wreck, and the potential that my car may be on fire. After making those statements to dispatch, flames shot forward from my hood and I was able to move away from my car. The fire department arrived on scene but not before the flames had reached 12+ feet as they were taller than the fire truck. The firefighters were able to put out the flames. My car engine was completely melted from the fire. At this point, the dealership, insurance agent or any other representative has determined a cause of the fire or has looked at my car. No warning lights to indicate a malfunction was visible prior to the incident. No noises or engine malfunctions were noted prior to the incident.

    My 2012 Hyundai Sonata Hybrid has not had any resolution after the motor seized in 2016. The dealership service department said the motor needed to be replaced in 2016 but refused to honor the warranty. I drove the car part way home when the motor seized on the highway. At that time I made multiple attempts for Hyundai to honor the warranty. The Sonata had 58,708 miles on it. It had to be towed has been in storage since that time. Hyundai since has placed a recall on the motor. The Hyundai customer care center is refusing to cover the cost of towing and loaner vehicle while ‘they check it out to see if it covered under the recall’. I would like to know what rights I have? Will I need to initiate a law suit to get resolution? My VIN indicates it is included in the recall. I contacted a Hyundai dealership who stated they would get back with me also. They also have not contacted me to date. Six years has passed and Hyundai has been fined billions according to your website yet they do not respond in any reasonable fashion. Do have have any information about what they are required to do for someone in my position? It has been pointed out to me that many other parts will need replacing such as the hybrid battery, connectors, hoses and so on due to the time lapse which Hyundai purposely created by their refusal to act in a timely manner. I am making a complaint against them for the above reasons.

    The bulbs keep blowing out and now the wiring harness is burnt. I have replaced bulbs multiple times and I have an upcoming appointment at my local dealership on April 4th. My concern is I thought bulbs were supposed to be replaced every few years not 7-8 in one month. Now due to the fact that the lighting housing assembly is melted it will not hold any bulbs. I have a small child that sits and the back and has a medical condition and I am scared to drive (at night especially) if he needs to go to the emergency room/doctors appointments due to the fact someone may hit me from behind because I have no lights back there. Where I stay every time I see a Hyundai Sonata it never fails they are always missing a light in the back due to the light assembly has melted. This is a safety concern for not only my children but for me. I am also concerned that due to it being melted it could potentially catch something on fire.

    Limp mode on the 16th of march, no symptoms prior to entering limp mode. Check engine light was illuminated and blinking & a knocking sound came from under the hood, along with not being able to get over 1800 rpms before having to shift. Drove back home until the next day on march 17th went to try to take it to a manufacturing company and did not make it. While in the middle of driving it had a loud bang under hood and left me on side the road. Could not crank it again.

    I was driving inner city about 40 mph on 3/16/22. Vehicle lost power while driving. There were no warning signs, no check engine light, nothing. It just died while driving. I was nearly hit in the back by another vehicle with my 2 small grandchildren in the back seat. I was stuck in middle of road with 2 grandchildren at night in the dark around 8pm in the rain. The roads are slippery and wet during rain. Many cars passing had to jump over without warning because my car was just sitting in the middle of road. It was not safe for me and my grandchildren to get out of the car as it was heavily raining. I got out and stood on side the car until a passer by in a car pulled over to help me push the car out of the middle of the street until the tow truck arrived. Tow truck finally arrived 2 hours later. This car always stalls with no warning and did not crank. It had to be towed to nearby repair shop. My grandchildren and I had to find a ride back home.
