2020 Tesla Model Y FORWARD COLLISION AVOIDANCE

The automatic braking came one while I was driving 70 mph on Hwy 86 through New York State as we approached 3 of the 5 or 6 overpass bridges. My speed dropped quickly to 50 mph, at which point I hit the accelerator to get back up to highway speed. A similar behavior happened several times on this trip when going though an S-shaped curve. Similar behavior also occurred at slower speed ( 30-40 mph) when a car turn in front of me when the car was about 1 block in front of me and turned safely and cleared my path easily. I would have not braked in this situation.

Vehicle routinely forcefully applies the brakes for no apparent or warranted reason causing vehicles behind to take evasive maneuvers to avoid striking our vehicle. The vehicle on several occasions has also unexpectedly veered out of our lane into another lane, into oncoming traffic or off the road.

I was driving in a "train" of vehicles at about 65 mph using "autopilot" when my Tesla model Y slammed on the brakes when the paving changed color. I was almost rear-ended by the unsuspecting car behind me. Emergency braking without a valid reason, or even an observable reason, has occurred several times since we took delivery of then car two years ago, but not as severely. I am reporting this 2021 incident now due to the recent publicity. I urge the NHTSA to clamp down on beta testing of vehicle automation by unsuspecting new owners. Vehicle automated driving on public streets is a threat to public safety.

Phantom Braking constantly. Forward collision whole on Autopilot. Tried recalibrating the camera and the problems persist.

The model Y will randomly brake while at freeway speeds. I've seen it go from 80 mph down to 60 mph before I could react. In one instance a semi-truck had to swerve into the left lane to avoid hitting us. The problem has persisted for months and, when reported to Tesla, they denied that it had happened. Consumer received the report from Tesla stating no malfunctions or alerts present. Autopilot and cruise control will adjust vehicle speed for different reasons. Consumer could be override it with the accelerator pedal without canceling driver assistance features.

I have noticed when using Adaptive Cruise Control on my Tesla Model Y that it did phantom braking on me. It has only happened to me about 5 to 6 times and it scared the heck out of me.. Don’t know if I was getting close to a Semi truck and it pulled that phantom braking, but there was a time it just did it on its own when there were no cars around. AutoPilot I have no issue. Hope Tesla comes up with a software fix soon to resolve this issue as I love my Tesla and its a great car to drive..

At multiple occasions, there has been Phantom Braking occurring when on the freeway even when there is no-one ahead of me. Usually does occur when there is a truck next to me.

When cruise control is on, the vehicle suddenly brakes. I only put cruise control on the freeway and it has happened 4-5 times over the course of last year, as recently as 2 weeks ago. I had to take over operation of the throttle and removed cruise control to make sure it wasn't going to cause any issue in traffic.

The car keeps phantom braking at highway speeds when there are changes in the color of the road surface or sometimes when overtaking a slower car or truck in the right lane.

Whenever I have my car on cruise control on the highway it will randomly brake hard almost causing an accident behind me. I’ve noticed it does it more in express lanes with thin cone dividers / traffic on the other side. I worry it’ll cause someone to slam into me one day.

The contact owns a 2020 Tesla Model Y. The contact stated that while driving at an undisclosed speed with the cruise control set at a designated speed, the cruise control feature would malfunction and reset the speed to 20 MPH slower than desired. The contact stated that no warning lights were illuminated whenever the vehicle would suddenly decelerate. The vehicle was not diagnosed or repaired. Neither the dealer nor the manufacturer had been notified of the failure. The approximate failure mileage was 20,000.

This has happened multiple times over the 1.5 years that I have owned the vehicle, but it happened twice again today. The issue I am having with the vehicle is with Phantom breaking. When "Autopilot" is engaged, and the vehicle is travelling along a fairly straight path, occasionally it with brake suddenly for no apparent reason. This can have no real affect, or like today, when driving in heavy traffic this can be the catalyst for an accident or at the very least road rage (as the person behind thinks you are brake checking them). As stated, I've had the car for 1.5 years and this has happened more than 15 times, and I drive the vehicle very little and use Autopilot even less. In my opinion this feature is not quite ready for daily use and should either be corrected or removed.

While using the Tesla auto pilot in highway conditions the car would suddenly break or slow down as if the car was trying to avoid another car. There were no other cars in the area. This has happened several times but only in auto pilot.

I saw the article today that other Tesla Model 3 and Model Y drivers were reporting phantom braking. My model Y has been doing this at a specific spot on the 5 Fwy south in the carpool lane in Santa Ana, CA. I now avoid that spot. I thought if it helps to be able to repeat this problem for investigative purposes I can duplicate it at this location.

While using the autopilot the car will suddenly slow itself even though there is nothing in front of the car. It happens most often when approaching a large vehicle or truck that is in the lane next to the car. It seems as though the autopilot system is spooked by the truck even though it is staying in its lane. Similarly, there are 2 spots on I-25 in Colorado where the sudden braking happens regardless of what is around the car. It may to do with recent construction because in both places the car slows suddenly at the same point nearly every time I pass through. It was happening at one of these spots after the construction had moved the lanes. The lanes were marked very well and the car had no problem before or after this point. But when passing through the car suddenly slows. The danger is that a car driving behind me would not expect the car to slow down for no reason. A potential rear-end collision danger. Happy to give more detail to add context.

The Traffic Aware Cruise Control will suddenly and inexplicably agressively slow down or even slam on the brakes for no reason. If someone were following me close on the freeway, I would be rear ended. This behavior has been happening to me for almost 3 years now and has not improved, even though it is controlled and upgradeable via software. This is a known and far reaching problem that lots of Tesla drivers have experienced and have named "Phantom Braking". I have video of some of my incidents as well as Canbus data, showing how aggressive it can be in slowing a car down, for no reason. Unfortunately, many Tesla owners now refuse to use TACC or AutoPilot since we feel it is too dangerous to use when other vehicles are nearby. I've opened support tickets with Tesla in the past for this, but they claim that there is no problem, and others have heard the same thing as well. Please look into this major safety issue with Tesla's so that we can feel safe fully using our vehicles again. Tesla likes to say that their AutoPilot feature is safer than a human, but clearly this is not the case when it has such a major software fixable bug as this. Thanks for listening and I hope that you can both see what a safety issue this is and help persuade Tesla to fix it, for the safety of us and every other driver around us.

Now that Tesla had disabled the car's radar in favor or a vision-only ADAS, I started getting many forward collision warnings when using Autopilot on curvey roads, mostly when exiting the curve.

I was driving on a clear day with trees shading part of the road when suddenly and unexpectedly the car decelerated abruptly. If another car had been tailgating me I fear it would have rear-ended me.

My vehicle fail to stop when another vehicle was in the middle of the road. My 2020 TESLA MODEL Y did not stop and did not alert me in a upcoming collision incident. My vehicle fail to make a full stop with and without using autopilot.
