2018 Hyundai Elantra: fire, smoke or burning smell

Filed Oct 23, 2025 · Brakes, Electrical · OH

We were heading back to Ohio at Mile marker 8 75N Kentucky when we heard a boom. Then we saw smoke as my husband was pulling over. We jump out to get our child out of the car seat and at the same time a pickup truck pulls up with two guys. They yell that our cars on fire and began putting the fire out with a fire extinguisher. We had an oil change before we left Ohio by Valvoline. This area of the hwy isn't really patrolled and only has a volunteer fire department. A constable just happened to pass by US on the way to Indiana.

While driving, heard a loud pop then smoke came from the engine. The electrical system flashed then went out. A passer by coming from the opposite direction stopped and told me that my car was on fire. I got out and there was a small fire on the groung underneith my car. Then opened the hood where there was a small fire behind the engine. Another truck passing by had a fire estinguisher and put the fire out. There was oil all over the road. Called a wrecker service to come and pick it up. Upon delivery of my vehicle, there was oil all over the wrecker. I'm very lucky to have had someone come by to put the fire out. I could of been in the car and been burned. The insurance company has been out and done a full report on it. There were no warning light that came on detecting any issues.

I bought the car about a month ago. And today I experienced the car while driving at 55mph when I went to accelerate to go the speed limit of 65 on the major highway going into salisbury, md that the car wouldnt speed up. And about 30 seconds later the transmission seemed to have down shifted a couple gears due to the rpms going from 4600ish RPM down to 2000 rpms and than the car went back to normal. When I had gotten into salisbury and had to stop it braked just fine but when I started to drive again it start to feel like it was stalling and it's been doing it now for the whole day. As well as a burning smell which I'm 99% certain is the clutch. I have worked the automotive field for about 7 years. I have a dct transmissions 2018 hyundai elantra sport tech package. I went in the forum on facebook and some else has posted the same issues. And many other comments. I will be taking mine to the dealership after christmas is over. But I'll list screenshots below
