NHTSA Complaint #11627134 — 2023 TESLA MODEL Y

I have reported this same issue twice before. When on cruise control, the car brakes unexpectedly. My 2nd and most recent report was on [XXX]: "... I had already disabled "Apply Brakes when Regenerative Braking is Limited" under Dynamics on the screen. (see photo) He showed on the screen, under Autopilot, that I could disable Automatic Emergency Braking, which I did. I was concerned that this warning pops up: "The vehicle will not automatically apply the brakes even when a collision is detected" (see photo) but he suggested I try it to see if it would solve the cruise-control braking. I was hopeful, and disabled it, knowing that it might take a while to know if that solved the problem. I drove the 30 miles home on the frontage road instead of the interstate, and when there were no other cars around, I set cruise control at 50 mph, the speed limit. I came to a series of small hills in the road, and was reminded of the first time the automatic braking happened, on a 60 mph road with longer amplitude hills of greater height. Amazingly, it happened again! Pretty significant braking and slowed me to 25. This time I waited it out to see if it would resume the cruise control at 50. It did not. I have since restored the Automatic Emergency Braking as that seems important for a crash situation. I have restored the "Apply Brakes When Regenerative Braking is Limited" since that obviously was not the problem either." I did not use cruise control again until [XXX], when I happened to be returning home from Silver City to Las Cruces and was on the same highway, [XXX], where the problem first occurred. It is a 2-lane road and often there is no traffic, so I felt safe trying cruise control again. I set it at 55, the speed limit, and after only a few miles the car braked again. I do not use cruise control anymore, and was dismayed to find that Tesla is again offering a free trial of autodrive! This is a huge safety issue!
