NHTSA Complaint #11612010 — 2012 HYUNDAI SONATA

When driving (at any speed) car error message comes up that says "Hybryd system warning safely stop and do not drive" then when that light goes out a new warning comes up that says "check brake" at this time the car will slow itself down until the car stops completely - even if you have your foot all the way on the gas pedal. There's no pattern to when it happens, it can happen on any drive at any time. When this happens all I can do is turn the car off and wait to restart car to keep driving. The front brakes have replaced, the back brakes and rotors have been replaced and the brake pump was replaced but, the problem persists. Primarily this is a safety issue if I'm on the highway, or anywhere I can't really pull over. A perfect example of this is on 8/31/2024 my son received a warning citation for "Improper Stopping" the remarks on the citation say " was parked on side of roadway due to car not wanting to accelerate but, could not move outside of the roadway". Basically the car slowed down but, completely shut down in an area that wasn't safe to be parked or sitting. It's dangerous for me and any other driver on the road that's behind me or on either side of me. After researching online it seems this is a common issue that Hyundai has not figured out yet. Other consumers have spent thousands on repairs thru Hyundai and still have not resolved the issue. Please help me figure this out.
