NHTSA Complaint #11691681 — 2023 HYUNDAI PALISADE

We were almost in a major accident with 6 passengers in our 2023 Hyundai Palisade. On Wednesday, Oct 1, 2025 we were driving our Palisade to McDonalds off Highway 98 (Navarre Parkway). Please see pics. When we left McDonalds we went on a side road to enter Highway 98. Now on this side road (see pictures) there is some type of metal grate in between the road...well when we went over the grate approaching the stop sign the Palisade went into an immediate violent shudder and there was no control of the vehicle as it felt it was shut down even though I could tell it was on by the interior lights on the gauges. I had absolutely no control of the vehicle. Yes, I was the one driving. I could not brake and the Palisade continue to roll past the stop sign onto Highway 98 with on coming traffic. I couldn't even steer the car because its as though the car had no power. It was totally dead. With my foot pressed hard on the brakes that still did not work I tried to start the car and then it came on. My wife has told me that she experienced this issue at least six times passing this same road and others similar to it. This was the first time I experienced it and we were lucky we were not hit by oncoming traffic. Again, no brakes, no steering control. We were traveling at a slow speed as we were approaching the stop sign on that road with the metal grate, maybe 5 mph or less, but as soon as we went over the grates...all control of the Palisade was lost. Please advise us what to do...as I said we almost had a major accident with 6 passengers because the Palisade did not function as it was designed to do.
