This mainly concerns the forward collision detection sensor, if that’s even what it’s actually called. My vehicle is available for testing and inspection. I was driving on an interstate, with my adaptive cruise control set to 75 mph. I was in the left of 3 lanes when got to a curve that went to the right. As I came to the beginning of the curve, all of a sudden my dash is warning me of a forward collision and the car started braking hard on its own. There is a metal guardrail that separates the 2 sides of the interstate and cars are also coming from the other direction. There wasn’t anyone behind me, thank goodness. If there had been, I can’t say for sure what would have happened, but it would not have been good. It took a hot minute for me to figure out what it was doing so I could stop it and get back up to speed. It scared me when it happened. When I go the same way without my cruise control on, it doesn’t happen. That’s how I know it has something to do with how it’s all connected. This has happened twice at 2 different places since I got the car in May of 2024. I don’t use my cruise control hardly at all now because I’m scared it’s going to suddenly brake again. I wasn’t sure what could be done about it. I put the info on the Hyundai owner surveys but nothing ever happened. I found the NHTSA completely by accident. I want someone to inspect it and try to recreate it, but it’s an awfully dangerous thing to try. Nobody has yet. It’s not like it’s a noise or a rattle. The only thing that I would consider a warning was the crash detection warning on the dash screen that flashes red. That started right about the time that the brakes were activated.
