I bought my car used from a private party in March of 2022 with around 132,000miles. In a year's time I have replaced the rear passenger side tail light bulbs 3 to 4 times, the whole light assembly, and the wiring harness twice due to the bulb getting to hot and the plastic caught on fire the first time and melting the second. Noticed the smoke when I pulled into a gas station that day and opened the trunk quickly and beat the small flame with a small blanket I had in the trunk. My kids sit in the back seat. So I'm constantly worrying while driving when they are in the back. The headlight bulbs go out quicker in this vehicle as well. I've had to replace the headlight bulbs 3 times already. This is also too close to the fuel pump for this sort of thing to happen in my opinion. This needs to be resolved A. S. A. P.

My 2013 Hyundai Sonata has been declared totaled by my auto insurance company and "unsafe to drive" by Hyundai Corporation. There is a case number associated with my car at Hyundai. While driving down the street my engine begins smoking and everything shuts off. I was scared and uncertain of what was happening. I had to dodge cars to get off the road. I have supplied more than 15 pages of maintenance records, Which has proven I have taken care of my car. The engine has locked. The first representative stated Hyundai Corporate will pay for repairs - a new engine. The second representative stated only if I had a warranty will they assist me. I believe I'm getting the run around.

I was driving one afternoon on my way from the nail shop with my sister my boyfriend & his friend when my call stalled in the middle in the street after managing to get the car out of the street it burst into flames.

After not knowing what caused this stalling or fire I received a recall for my car in the mail.
