FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
While driving on C-470 in Colorado, eastbound approaching the Quebec St. exit, I was in the right lane. A car was exiting the highway while I continued straight. I was 2 sec behind this car and the car was in the exit lane, while I continued on the right lane. However, the highway curves to the left here. A straight forward view shows this car mostly in front of me. The Model Y braked excessively, from 65 to 45-50 before I could press the accelerator to continue forward. I would be worried of a rear end collision if there were a car behind me.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I've been having problems with phantom braking, primarily on highways. This problem has gotten much worse in the last month or two. The car will unexpectedly brake while either autosteer or adaptive cruise control are engaged while driving on the freeway, and typically (although not exclusively) when my speed is approx. 70-80 MPH (where speed limit is 75-80 MPH). This will happen approx. once every half hour, although it is sporadic and often happens in spurts. Until about 1 month ago this would happen only while autosteer was engaged. However, during the last month or so ago this has also been happening while adaptive cruise control is engaged (without autosteer engaged). It happens most often when I am in the left lane passing a semi-truck which is in the right lane, although it happens other times as well. Always without any warning. It has happened a total of probably 20-30 times in the last 2 months (approx. 5,000 miles). Sometimes it manifests as a gentle, almost tentative tap on the brakes, whereas other times it is a fairly jarring with sudden hard braking. It has not caused any accidents or incidents, but I am concerned about it happening when a car may be behind me. Because of that, I will often disengage cruise control or autosteer if other cars are close behind me. My car software is equipped with Full Self Driving, but the FSD (beta) has not been downloaded.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
When driving with cruise control on I experience issues with sudden braking. Sometimes it seems like it may be an error due to on coming traffic (particularly trucks), but sometimes it’s due to blind curves or small humps (such as an interstate bridge/overpass) where the pavement is a different shade. Typically I’ll be at cruising speed 60-75mph and braking will be sudden and aggressive, to about 45mph. This has happened numerous times since purchase in June 2021.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The cruise control on my Model Y frequently slams on the brakes for no apparent reason (no obstacle or vehicle in my lane). This happens at all speeds (from 30mph to 75mph). The cruise control is so unsafe and scary that I will not use it at all with other passengers in my car or when I have a car following me. My car slams on the brakes so hard it makes it completely unsafe for me and the people following me. In my opinion, it drastically increases the chances of being involved in a rear-end collision. There is no ability in the Model Y to use cruise control that is not adaptive-based. Until this problem is fixed, Tesla needs to offer a cruise control option that is 100% controlled by the driver (standard cruise) where the speed and brakes cannot be changed by the car. My car has not been inspected by the manufacturer and this has not been reported to the manufacturer because it is a widespread and known problem, and Tesla is not currently doing anything to help others who have reported the issue.

SERVICE BRAKES, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The adaptive cruise control and lane assist on the Tesla Y models are defective and pose significant risk to drivers, occupants and surrounding traffic. Phantom braking and sudden slowing are common place and many times unpredictable. Countless times when oncoming traffic in the other lane approaches, sudden braking and aggressive slowing will occur especially if this happens to be a logging truck or larger vehicle. Coming under any overpass or bridge will also produce phantom braking. This will happen countless times in a single trip rendering the adaptive cruise useless. I complained to Tesla and was called by the corporate office in Denver and told that this is a reality and it was my responsibility to "teach the neuro-net" that it's phantom braking was an error by accelerating aggressively during those episodes and producing "bug reports" to Tesla! I have had this Tesla 3 months now and have stopped using the cruise control and lane assist because of safety concerns. My attempts at "teaching" the computer the correct response has utterly failed. I have had 3 episodes that I know of that someone following closely behind me had to take evasive action which precipitated "road rage" type behavior on their part for no fault of my own. Tesla has made no effort to correct this defect and have even cancelled my repair appointments stating it was"not needed". Every Tesla owner I discussed this issue with has a similar experience. Eventually someone will get injured or killed due to this defect.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The contact owns a 2021 Tesla Model Y. The contact stated while driving with the cruise control activated, the vehicle erroneously applied the brake. The contact stated that the brakes were immediately released independently of driver assistance. There were no warning lights illuminated. The failure had occurred approximately 6 - 10 times. The contact had not taken the vehicle to the dealer. The manufacturer was not made aware of the failure. The approximate failure mileage was 1,000.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
When using basic Tesla Autopilot (AP) on side roads or highways the car will experience “phantom braking” with no other vehicles around. Phantom braking is where the car will slam on the brakes because it sees a safety issue ahead. I was driving on a highway at 60mph and engaged AP after about 5 miles the car brakes hard and fast down to around 40mph and then sped back up to 60mph after about 50 yards. It did this twice on the drive home. If we have an 18 wheeler behind us and they’re not paying attention they would definitely rear end our car.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA
The display of the rear view camera on the screen is not synched. Sometimes it shows something that happened moments earlier. For example, it may show me as I am walking toward the car. Then it “lags” as you back up, meaning that it shows you in an earlier position than where you really are. This is super dangerous as it may not show the real time presence of another car, a pedestrian who is crossing behind your car as you back up, or an object. It also give the driver the false sense of being in the wrong place. We have two Teslas, this is a model Y and the other is a model 3. We have experienced the same problem in both since Tesla pushed a software update in January. I notified Tesla and asked for a repair. The response was that a software patch would be forthcoming. That was weeks ago. Again, this is a super dangerous flaw in the software for the display of the back up camera. I am worried that a pedestrian will get run over by a Tesla driver who does not “see” that pedestrian in the back up screen, or a crash.

Car rapidly brakes when in cruise control and auto pilot. Will also rapidly brake when a car passes by. It will always be random and sudden. Also, occasionally the screen will turn off and I will lose the screen completely and not know my speed.

with cruise control on, when large vehicles (in their respective lane), would approach in opposite direction, the car would brake. Sometimes lightly, once (tour bus approaching) at 60 mph, the brakes were slammed on, with the car behind us nearly rear ending us

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Hello, my Tesla Model Y frequently brakes unexpectedly causing me concern in traffic I could be rear-ended. This happens when engaged in FSD Beta software version 10.9 currently and has happened in all previous versions of the software as well. I have held a commercial drivers licnese and want everyone on the road to be safe as possible. The car brakes hard reducing speed 15mph in a second. The car has also attempted to take off from a red light when the first car at an intersection treating it as a stop sign when when several lights are present indicating a solid red and the screen in car shows me solid red as well. I have had to intervene many times to prevent accidents.

VEHICLE SPEED CONTROL
Several times (at least 4 times) on various trips, I was driving on the interstate going at least 70 mph and I had cruise control on. I DO NOT have autopilot. If the highway was blacktop and I approached a white concrete bridge deck, the car suddenly brakes. Also, twice I was next to a tractor trailer (I was in the left lane and the tractor trailer was in the middle lane to my right) and the car braked suddenly. I thought the car “anticipated” that the trailer was coming into my lane. Regarding the white concrete bridge deck, I wonder if the car “saw” a wall ahead and that is why it braked.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
In 16 months I have experience 2 episodes of dramatic emergency braking while traveling at highway speed in the carpool lane adjacent to a concrete barrier wall estimated 5 feet high on the left side of the vehicle. The car decelerated from 65 mph to roughly 30 mph in roughly 2 to 2.5 seconds. Had someone been following at an unsafe distance an accident would have occurred. Thankfully it did not. I never experienced this in my previous Tesla Model S. Overall I love the vehicle, but these 2 incidents were disconcerting.

The vehicle engages automatic emergency braking frequently and repeatedly without reason, especially on two lane highways with oncoming traffic. This occurs during the day and at night. The vehicle also engages phantom braking (without emergency braking notifications) during normal driving on freeways and highways. Video of this incident is also available.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Traffic aware cruise control frequently hard brakes / emergency brakes on 2 lane roads when large vehicles such as semis and dump trucks approach in the opposite direction even though all vehicles are properly in their respective lanes. This presents a serious risk of being rear ended as well as heart attack for startled passengers. TACC is so bad it's not just unusable it is unsafe.

While using TACC ( traffic aware cruise control) the car would suddenly break and beep warning sounds. Happened randomly and at various speeds but seemed to correlate most with trucks in the left lane. Some colors seemed to be picked up more than others. Bridges and shadows also triggered it. It was my first long trip in the Tesla Y and so experienced these horrible, unpredictable episodes around 40 - 60 times during an 8 hour drive mostly on highways - many of them two way
