NHTSA Complaint #11472961 — 2017 HYUNDAI SONATA

While driving my 2017 Sonata on a winding backroad my power steering suddenly locked up without warning, and I was unable to turn the vehicle left or right. Prior to this incident there were no warning or check engine lights lit indicating any type of issue with my car, and my power steering was operating normally. I hit, and jumped a curb striking a rock wall attempting to turn slightly left to keep myself in my lane, and on the road damaging the right passenger side rim and fender. After coming to a stop I noticed there were two warning lights that had activated. I immediately called my local Hyundai dealer (Imperial Hyundai of Milford Massachusetts) informing them of what had happened, and scheduled a service appointment to have this issue diagnosed. I was informed by the dealership that Hyundai is having issues with their electric assist steering motor, and computer module which controls the steering assist motor. Had this been my wife or son this would have definitely turned out differently, because I'm over 240lbs and could barely get the steering wheel to turn at all prior to hitting the curb. After shutting off the car, and then restarting it repeatedly for approx 30 minutes suddenly the service lights went out, and the vehicle started operating normally again. My appointment at the Hyundai dealer is on July 13, 2022. I was told Hyundai has extended the warranty on parts associated with the steering system, but they wouldn't tell me which parts are covered or not covered. That is the least of my concerns, because like I said had I not been the driver, or if this had happened at highway speed this could have been tragic. It's a serious safety issue
