The car is experiencing PHANTOM BRAKING. The vehicle incorrectly detects objects and brakes vigorously dropping speed really quickly. If traffic is following we could easily get rear ended. This happened over 10 times in a 100mile journey.

While driving on freeway car drastically brakes for no apparent reason, almost getting rear ended by car behind me. This happens while cruise control is on, several times! Very dangerous
The Tesla Model Y and I believe the Model 3 have a problem with phantom breaking. The problem occurs when we set the auto to cruise control on a two-lane highway. When we meet a large object (semi, garbage truck, propane truck) the car breaks and swerves to the right. This can create a very dangerous situation. The first couple of times this happened we almost lost control of the car. There is no warning before this happens. This problem can be easily replicated on cars without radar. It took us some time to determine what was causing the problem. We picked up our new Tesla Model last week and were not made aware of what would happen if we used cruise control on a two-lane road. We have since discovered that this is a known problem in the Tesla community and has been known for some time.
When on Traffic-aware cruise control, the vehicle suddenly brakes without warning, instantly reducing its highway speed by 7 to 12 mph. It occurs on the interstate, often while passing large vehicles, and on two-lane roads, usually when meeting large vehicles. Recently, as I was moving in front of a vehicle I had just passed, my car slammed on the brakes, causing the other vehicle to brake sharply to avoid hitting me. We have had the vehicle serviced by Tesla twice with no improvement. The service rep indicated it is a known problem that they have not yet been able to solve (unlike the manufacturers of my prior six vehicles with adaptive cruise control). This is a life-endangering fault and needs to be fixed. It is as dangerous as the rolling-stop issue that prompted a recall.
The car brakes are applied when a truck traveling in opposite lane drives by when the cruise control is engaged. This has also occurred when there was discoloration on the road surface in my travel lane. Fortunately, no auto was following my vehicle or there would have been an accident.
With AutoPilot engaged both during the day and at night, though more frequently at night, and driving on two lane highways, the car automatically brakes sometimes very hard causing your neck to snap forward, whenever it detects oncoming traffic. This is amplified at dusk and at night. There is no warning or time to override this. Making the vehicle dangerous to driver, occupants, or cars travelling behind the Tesla. Tesla claims that this is a known issue, but other brands with similar safety mechanisms do not have this "Phantom Braking' condition.
Model Y consistently slams on the brakes while on standard cruise control mode despite there being no cars or hazards around the vehicle. It happens at highway speeds and is very frightening and it’s worrisome that it will one day cause a major accident if someone is ever following too close.
AUTOMATIC EMERGENCY BRAKING with Adaptive cruise control on. I was driving with adaptive cruise control on, at about 50 mph on a two lane road. the first experience I had was at dusk on a straight road when oncoming traffic with headlights seemed to trigger the braking system changing the speed of the car by about 10 mph repeatedly but not every car or truck. When I entered a curvy road section, it didn't trigger the brakes. The second experience was around noonish on a straight road, a large oncoming truck seemed to trigger the Automatic emergency braking and brought me suddenly to almost a stop from 50 mph. I looked behind me and saw no one close to rear ending me but it was scary to almost stop in the middle of my lane. no confirmation by dealer or service center, no inspection by others, no messages or other symptoms prior to the failure. No chimes or warning when it happened. The first experience appeared January 14, 2022 with approximately 350 miles on the new car. The second experience happened January 19th with approximately 450 miles on the car.
While on cruise control the car brakes aggressively with oncoming traffic and when passing large vehicles on the highway. No way to disable this feature to use a standard cruise control. This seems to be a problem mostly with large vehicles on the road.
When using cruise control on normal two way traffic roads during the day or at night: the car will brake aggressively because of proper oncoming traffic from the other lane. The system has been very poorly designed such that it only works on wide separated highways and there is no way to switch off this feature. I have already had two near accidents where the vehicle behind me didn’t expect my car to slow down so quickly for no reason. This is extremely dangerous.
