NHTSA Complaint #11519013 — 2021 TESLA MODEL Y

I was driving down the highway. The weather was clear. Sunny. The road was dry. Middle of the afternoon. I was using the Adaptive Cruise Control. I was driving the speed limit, 70 MPH after driving for a couple of hours, the car had about three different times when it felt like the brake was tapped, the car slowed a bit and then regained speed. I stopped at my destination for about 4 hours and then returned home. Same roads conditions, sunny, dry road, etc. Same road, 70 MPH, the car suddenly hit the brakes HARD. Slammed might be too strong of a word because it's not like the car left skid marks on the road, but the brakes hit very, very hard. The car slowed to 25 or 30 MPH. Fortunately there were no cars behind me or me and my wife could had been killed right then.
