VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
When driving with the cruise control on, the car suddenly and rapidly brakes for no apparent reason. Nothing in front of the car. Problem has happened multiple times. Very hard Braking that if someone was behind us it would likely have caused an accident. We no longer use the cruise control because we are afraid of it causing an accident.

SERVICE BRAKES, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
On a cross-country trip from Washington, DC to Oklahoma City on Feb 5th and 6th (Saturday and Sunday) I tried to use the "adaptive cruise control" for the first time. Terrifying. The car would be driving along at 80mph, and then it would suddenly slam on the brakes, seemingly without provocation... with a 30-35mph sudden deceleration (absolutely nobody/nothing in either of the lanes in front of me). This was not while using the "full self-driving" feature, as I did not pay the extra $10k for this functionality, only the adaptive cruise control. Another very disturbing thing was that when the adaptive cruise control was enabled, it would not allow me to turn off the windshield wipers... and every so often the wipers would just start frantically wiping despite only a small bit of rain hitting the windshield (again, disturbing, as it is very startling when it happens out of nowhere). Needless to say, after this happened 5 or 6 different times over these two days, I turned off adaptive cruise control and kept it off. Tried to contact Tesla service, but they kept dodging the issue so I stopped trying.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Car braked for now reason when the entire roads in front was clear and there was a car behind me. It was a hard brake which scared me and my family. That was very very close to being in an accident. Need compensation from Tesla for going through such an incident after paying so much money for the car.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS
Car slams on brakes at inappropriate times. Ex: 1. When a car makes a left turn across my travel lane several blocks away. 2. When a vehicle moves into my travel lane, going the same direction, several blocks in front of me. 3. For no reason I can discern. Cars behind me often honk. Could easily rear end me. Thankfully hasn't happened. You are welcome to inspect it. Don't think service center has tried to replicate the braking. No accident so not reports. Just very scary, thankfully. No warning lamps, etc. Anticipating question about dates, happens randomly, but pretty frequently. At least weekly. Speed also variable. Sometimes 35, sometimes 70, and in-between

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
We have had multiple incidents from July through Dec 2021when the vehicle is operating in cruise control and brakes hard for no good reason. Most of these are on highway 86 between Tucson and Sells. For some of those incidents there was an oncoming school bus, which may have been the visual trigger. For others we do not know the cause.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
While using adaptive cruise control on I-25 making round trips between Albuquerque and Ft Collins, I have experienced numerous (dozens) phantom braking events. They are so frequent that I have stopped using adaptive cruise control. Almost all of these events occur when there is no traffic and no discernible reason for braking. In many cases, my first response is to look in the rearview mirror since I'm worried that if someone is behind me it would cause an accident since the stop is very unexpected. To date, there has not been a close call. The stopping varies between slight hesitations causing 1-2 MPH decrease to dramatic decreases of over 20 MPH. I have made numerous 'bug reports' using my voice in the car immediately after many of the events. I also scheduled a service call but was told that they examined the software and could find no problem. There is no warning of an impending braking event.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
On multiple occasions the car triggers emergency braking when no obstacle is in front of the car, often at high speeds. The car is not equipped with radar, and relies entirely on camera-based adaptive cruise control. this is a safety risk and possible rear end collision cause. Due to the lack of radar, the vehicle also accelerates to desired speed slowly when using adaptive cruise control while on interstate. Often times resulting in traveling under the speed limit for an extended amount of time, causing a safety hazard.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS, UNKNOWN OR OTHER
These issues occur w/ no warning, occur randomly, in all conditions. Issue 1. Vehicle randomly slams on the brakes with no obstructions or vehicles in front. This occurs at highway speeds as well as neighborhood speeds. I'm worried about being rear-ended. This occurs daily. Issue 2. Vehicle thinks oncoming traffic is in same lane and attempts to emergency stop. Issue 3. Upon changing lanes, using auto lane change, vehicle serves back I to lane for no reason.

VISIBILITY/WIPER, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Wipers have frozen down in place. Car is garaged and the buildup was from the road and not parked accumulation. New car <7k miles. Phantom breaking on the autopilot system where it will slam on the breaks always at some points on a commute and when driving in some conditions such as oncoming opposite side of road traffic at night with headlights on. The car will momentarily and to an extreme degree sometimes slam on the breaks.

SERVICE BRAKES, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
When using autosteer or adaptive cruise on I5, our car performed a phantom brake that cause the truck behind us to nearly flip over in order to miss hitting us. We were not in the lane by the divider, there were wide open lanes in front of us to the left and right by half a football field and no overpasses at the time. We slowed from 69 to about 39 before I could correct the braking. This happens so often we do not feel safe using the cruise control at all.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, VEHICLE SPEED CONTROL
This has happened multiple times. I am on the highway and have the cruise control set. The car suddenly decelerates but there is nothing in front to cause this. It is very jarring to me as the driver and to those behind me. When it happened during the day time I think it reacted to a shadow in the road from an overpass. It happened last night when it was dark. I had stopped using the cruise control because of the uncertainty, but decided to try it again on my trip yesterday. I received the car in September and I believe this has happened four times. I am reporting this now because I heard of the investigation. Now, I will keep closer track of the times, conditions and other facts. I have not reported it previously to Tesla, but will do so now. I looked on the Tesla forum and it is clearly a known issue.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
Autopilot suddenly breaks to a dangerous levels while driving in the highway. Sometimes this happens with incoming cars/trucks on the other line. I have to manually take over control as I am worried I might be rear ended. These events are very likely to happen at least once on a given commute. This sudden braking also happens while going over a certain bridge. This has happened to all drivers in this car.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
While driving on the interstate (divided) highway at 73 mph with adaptive cruise control engaged, the vehicle abruptly braked. There were no other vehicles or obstructions within 250' at the time of braking. No warning lights or messages appeared. To correct the situation, I immediately pressed the accelerator to increase speed. Conditions: daylight, dry road surface. If another vehicle was following close by this could have caused an accident. I've had the car about 7 months and this type of braking has occurred 7 times, all with no vehicles nearby. It has happened both in the daytime (6) and night (1) at similar speeds mention above. I brought car in for service at Tesla on two occasions for this problem and they could find no faults in the software or braking. Basically, I was told Tesla continues to update software.

UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I DO NOT DRIVE THIS CAR OFTEN, BUT WHEN I WENT ON A ROAD TRIP FOR TWO WEEKS OVER CHRISTMAS I NOTICED THAT THE CAR WHEN IT WAS IN CRUISE CONTROL WOULD PICK UP VEHICLES COMING TOWARD ME ON A TWO LANE ROAD AND SUDDENLY SLOW DOWN. IT GOT MUCH WORSE COMING HOME WHEN I WAS IN NEW MEXICO ON I25 GOING NORTH. IT WOULD SUDDENLY SLOW DOWN COMING UP TO A CREST OF A HILL WITH NO OTHER VEHICLE AROUND ME. IT ALSO PICKED UP SEMIS GOING SOUTH THAT WERE HUNDREDS OF YARDS AWAY FROM ME. IT HAPPENED NUMEROUS TIMES AND SCARED MY WIFE. WHEN I WAS HOME I SET UP AN APPOINTMENT WITH TESLA SERVICE. THEY LATER CANCELLED IT AS THEY DID NOT SEE IT AS A PROBLEM.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Per previously reported cases, by Tesla Y suffers from “phantom braking” when I am using adaptive cruise control at highway speeds. In general it will decrease up to 20MPH very suddenly. This is always in response to a falsely detected hazard; it will sometimes do the same when passing a vehicle that has exited an off ramp and has break lights on but is no longer in my lane of traffic. in general i drive with maximum 5-6 car lengths in my adaptive cruise control and this should not be happening. This has been an intermittent but ongoing issue through 2021; have not experienced in 2022 but have not done a lot of high way driving. Scares the heck out of my passengers. Love the car but please fix the software or it will be my last Tesla.
