On 11/5/2019 while driving steering wheel locks up throwing a eps code. Had to pull over in 55 mph traffic. Lucky I was able to get off the road. Turned off the car and restarted it and the eps light was gone. I made it home. On 11/7/2019 on the way to dealership when I lost all power steering and had to have the car towed to Hyundai of valdosta, where it currently sits. This is really dangerous.
All dashboard lights are turning on. The car loses power steering. The car will at times not turn on. This happened a few months after I purchased the car. Hyundai can't seem to find the problem. The problem eventually goes away by itself for a few months and reappears again. We had the fuel sensor and battery replaced. They said my alternator and starter is still good. The car never stalled during driving only looses power steering which can be dangerous while driving. We noticed when we adjust the steering wheel up and down, it cleared the issue for a few months as well. I believe 2015 Hyundai Sonatas are experiencing electrical issues. I read online other owners having the same issue.
