VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I was driving to and from mammoth lakes California. Middle of the day, clear weather, with no other cars within thousands of feet if me. I put my vehicle into adaptive cruise control (not autopilot) and several times during the drive the brakes would slam to the point of reducing my speed from around 70 mph to roughly 40 mph very quickly. It was extremely happened and was repeatable but with no known reason.

SERVICE BRAKES, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Unexpected and rapid slowing/braking of vehicle since new in November of 2021. Occurs when on cruise control usually at highway speed, more often on open highways and have possibly (though not always) related it to cresting a hill, distant reflective “water mirage” on our western roads, passing large trucks, two lane highway having large oncoming trucks +/- on curves. On one occasion while passing a semi truck with car on my tail came within a foot or so of being rear ended. Many other occasions where got to point I do not feel safe using the cruise control. We have driven it from Denver to Tucson in November and back in May, both times was worse on wide open western roads, sometimes tho not always with bright sun, pretty unpredictable and random but often to point of not using any of our autopilot or cruise control functions with confidence of safety. No warnings, lights or prehappening signs. Reported and examined in Tucson on arrival there in Nov/21. Told would “get better with time” and further hardware updates. Hasn’t happened with city driving (tho rarely use cruise control. Happened a couple times on highway drives in Arizona while on cruise and thought maybe better until recent trip to Denver when it was as severe as November. Again contacted Tesla and told would lengineers are aware of problem and would be fixed with hardware app fix at end of June. Recontact them in July if still an issue. When serviced in November for this issue tech said he could see in computer log what was happening. When I set up appointment this time basically said live (or die) with it until June and nothing they could do til “hardware fix”. In blanks below I entered last episodes date. It has been ongoing from 11/2021 to present at speeds from 50 to 80 mph. Started with first trip when less than 300 miles til present 5436 miles on it. Could almost guarantee it would happen on highway trip with cruise control if you would like to risk your life on a test drive.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The vehicle phantom breaks spontaneously upon an interstate drive for 1.5 hours on cruise control it will slam on the breaks between 3-5 times when there is no car or object near the vehicle. This has been reported to Tesla and they do nothing and pose no solution to the problem. It is dangerous and going to cause accidents.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
This is a supplement to NHSTA Safety Issue ID 11467902. I requested service from Tesla. Attached is the service center's response writing that it is software subject to updates. This is unacceptable to me as the car is not driveable with this safety issue.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
During 350 miles of driving, I experienced over 35 phantom braking events. Most were while driving at 75 mph. Some were while driving 45 mph. It did not matter whether I was in Autosteer with cruise, cruise alone or driving manually. I turned off Emergency Braking on the screen. I still had incidents. Some incidents were severe to the point that I could feel the ABS. There were no other cars, structures, signs etc. in the vicinity. Had there been a semi following me, there would have been an accident. If another car, I could only hope that they had traffic aware cruise and emergency braking. This is unacceptable as it is so dangerous.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The car had a phantom braking incident where I was on the freeway with the autopilot set and the car slammed the brakes on because it thought it saw a person in the freeway. This is what it showed on the screen. The car decreased the speed from 70 mph to 40mph. There was no notification of this decrease. This has happened before in the car, but not as drastically and it doesn’t happen very often.

Recently, I had a long distance trip and and Tesla Model Y braked the vehicle at highway speed when it was on Advanced cruise control 3 or 4 times with obvious reasons. I had to push the acceralator pedal to speed up in order to avoid rear ended collision in a bumper to bumper traffic.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, LANE DEPARTURE: ASSIST
The brakes engage during lane assist mode as if to avoid something in the road although there is nothing there. This happens many times on a road trip from Phoenix to Los Angeles on I 10. It also happened multiple times on the freeway in town in Phoenix. It is very jarring
