I was driving and my car started beeping and the wheel jerked to the left and my car slowed down from 65mph to 20mph and almost caused me to have an accident. After I replaced the breaking module, my battery started shorting out and my car once again jerked off to the side and then slowed down abruptly from 65 mph to 20mph.

I drove a mile from my house and the vehicle stalled at a turn. The engine shut off. I tried to turn it back on and it did not. I have an electrical push button and it did not work. My passenger and I pushed the car out of the road into the back area of an HEB. We then opened the hood and the engine started smoking. I had called my boyfriend who then arrived. The engine continued to smoke and an HEB driver saw the incident. He came over with a fire extinguisher and sprayed it because they could see flames starting under the car. The fire department and police had been called. The car engine then went up in flames and my boyfriend used the fire extinguisher. The fire department arrived and went over to the car and cut the wires. Nothing on the car works. It has not been assessed because I only had collision insurance and my company would not come to assess it. They did tow it back to my house where it is sitting and not working. I can't even move it into neutral. There was not warning of this and I had driven the car to the airport (an hour away) and back five hours earlier that day and it seemed fine. The fire department said that if they need to be contacted they have a report on the incident.

We were driving and the engine just quit. We were able to safely get to the median. The minute the car was stopped we smelled something burning. We got the kids out of the car and to the other side of the road. We looked under the hood and could smell the burning but didn't see where it was coming from. Soon we were back on the side of the road waiting for our ride to pick us up. About 20 to 25 min later we saw smoke coming out of the hood. My husband called the fire dept and just as they arrived the whole thing lit on fire under the hood. The fire dept was able to put out the fire. Now we are waiting to have it appraised by our insurance company.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2014 Hyundai Sonata verdict →
