I was driving home on January 1, 2023 at 5 AM at about 60 mph on an interstate when I heard a sound come from the back of my car and then looked into the rearview mirror and smelled smoke and saw fire flames in my rear and side mirrors. I tried to use my brakes to stop my car, but the brakes would not work, so I took it out of Drive and put it into park... which slowed the car down and I was able to exit the car right before it burst into flames. The car is now a total loss.
Noticed after driving my Hyundai genesis and once running for roughly 15-20 mins once the engine has warmed up I noticed a bounce feeling coming from the front end(I thought)and then noticed my speed dropped and when pressure was apply to the gas pedal it wouldn't go, as the car slowed down by itself until it came to a complete stop I cutt the car off and began walking around to where I smelled something burning and then seen smoke coming from my front driver wheel to discover my brake had locked up for no reason. I left the car to cool down and returned to get it and luckily it was unlocked and was successful to drive it home(4min drive), a couple days later I had to take my son to school to where it did the exact same thing again, days later I had all braking replaced which failed to solve the issue. …
The HECU has been malfunctioning in my car for over a year now. It is an open recall for my make, model and year of car. I took it to Bob Rohrman Indy Hyundai and they diagnosed the failed part. This part affects my ABS. There are currently two warning lights on one for the ECS which is the traction control stabilizer and the ABS light is on. Meaning the use of the breaking system is limited and not working properly. I have asked the corporate Hyundai to uphold the recall warranty but I was advised they would not cover this because my vehicle has a rebuilt title. I drive my vehicle on a daily basis and I'm terrified of my brakes going out. The corrosion from the fluid is what causes the HECU to malfunction and it is so scary to think about. This problem was diagnosed and first reported to my his dealership on 6/23/2022.

The brake lines and fuel lines were corroded. The corrosion of the brake lines would lead to brake failure and the corrosion of the fuel lines would lead to a fire. The Hyundai dealer was the first to find the brake problem and after inspection by my mechanic, the fuel lines were also found to be corroded. I took my car in for a recall service at the dealer and after the service my brake light would illuminate when decelerating(with or without brakes being applied) .
I was sitting in my car with the emergency break engaged when my car started to roll back down my driveway. No matter how hard I tried I could not push the break in and the emergency break was on the entire time. My door is now crunched up from rolling back into a tree. It went all the way down my driveway, across the street and into my neighbors yard before my husband was able to get it to stop by pushing the break pedal as hard as he could. I bruised my shoulder trying to get out of the car while it was rolling away.
