2020 TESLA MODEL 3 Forward Collision Avoidance Automatic Emergency Braking Problems

In moderate city traffic, the emergency braking system sounded and engaged prematurely and harshly. I was not using any automatic driving features and was driving “manually.” A vehicle in front of me stopped, and I intended to slow then stop in a reasonable fashion. I have 25 years’ driving experience, and am well-experienced to do this safely. The emergency braking system suddenly engaged at about 25 mph, grinding my car to a halt. The driver behind me was not expecting such a short stop, and rear-ended my vehicle. No one was injured in this crash. My seatbelt trigger deployed, which tripped the pyro fuse, rendering my car undriveable. I could not move my car off the roadway and caused traffic clogs. The repair bill was roughly $9000 for my vehicle. The weather was clear, the street was dry and the sun was near high noon.

I have reported multiple times that the car suddenly brakes in the middle of the express way with no apparent reason. This issue is known as phantom braking. Tesla postponed the diagnosis of the car multiple times and I was told by the service department that the problem was going to be fixed by replacing the radars when I left the car on May 16, which they did not do. The last events of phantom braking occurred multiple times and even I continued stepping on the accelerator, the car continued to engaging with the emergency braking. This is a safety issue and the company has failed to fix it

"Phantom braking" issue is very real and very dangerous on my vehicle. Problem occurs while operating the car with Autopilot engaged such that the adaptive cruise control is in operation. Problem happens with or without also having the auto-steer function engaged. Problem is that the vehicle will suddenly, very unexpectedly slam on the brakes. This can cause the driver of the vehicle to go into panic mode and for obvious reasons is also very dangerous for vehicles that are following the malfunctioning Tesla. Sometimes, this sudden, hard braking occurs when a vehicle coming toward the Tesla makes a left turn in front of the Tesla at a VERY far away and VERY safe distance - so safe that the driver of the Tesla is caught completely off guard when the Tesla decides to slam on the brakes. And cars behind the Tesla are also caught off guard. Other times, this...

We were pulling our car from 5th floor of a parking garage and as the car was coming down the ramp into the 4th floor, it accelerated itself to a high speed, hit another parked car, and came to a stop hitting concrete pillar in the garage. Our car was damaged severely and all the airbags got deployed, smoke came out it. We are still in shock from the incident and it was a traumatic experience for all 4 members of our family including two of our children. It would have been catastrophic had there been another person around or if something more had happened. Our car unexpectedly accelerated and none of the warnings worked. Tesla car usually gives us warning (a shrilling beeping noise) when an unexpected obstacle, be it another car or a trash can or a human, is within a short distance of the vehicle. This warning...

Vehicle at least once per day automatically brakes. Phantom emergency brakes for no reason randomly when going straight on the road no objects come into obstruction for the cameras. Common Tesla problem. This needs to be fixed. It has almost caused a few accidents for me now.

The emergency automatic brake, cruise control and auto pilot feature gets disabled frequently. All 3 features gets disabled at same time. Contacted tesla service center in decatur-GA. They are saying they cannot find the problem and hence cannot solve it. They say the engineers are looking into it, and my car needs a firmware update. No estimated time to fix these issues is given. The service center advised that the car is safe to drive! Please help. Thanks.

Car engages self breaking while on autopilot without any particular reason. Repeated brhavior happened and almost caused rear end collision.

Vehicle was at a stop with brake engaged and then it proceeded to go full speed into a vehicle two meters away without acceleration pedal engaged. Emergency brake did not activate during or slightly before the collision. The brakes had to be engaged manually, but vehicle was already past a certain velocity on its own accord to be able to stop properly without damaging property or harming pedestrians.

The contact owns a 2020 Tesla Model 3. The contact stated while driving at various speeds and using Self Driving feature, the vehicle experienced phantom braking. There were no warning lights illuminated. The contact depressed the accelerator pedal and continued to drive the vehicle. Additionally, the contact stated while reversing, the vehicle inadvertently moved forward and slightly bumped into a guardrail. There was no further information provided. The contact depressed the brake pedal and was able to successfully reverse after several attempts. The contact also stated that the vehicle would fail to make normal beeping sounds and alerts while reversing. The manufacturer was notified of the failure and informed the contact that unless he provided the specific time and date of the failure, they could not assist. The vehicle was not diagnosed or repaired. The failure mileage was approximately 10,000.

While driving at highway speed, the vehicle's automatic emergency braking unexpectedly activated, without cause or warning, which caused a very rapid deceleration of the vehicle. Fortunately, the traffic on the highway was light and no other vehicles were around, but this "phantom braking" had the potential for a major collision. This is the first time this has happened on this vehicle. The vehicle has not been inspected by the manufacturer and there were no prior warnings.

There is a complete failure of the Autopilot (cruise control) feature and sudden braking when using. There is an extreme risk to personal safety when using this feature. On several occasions, I have been using this feature on the highway while going the posted speed limit of 65 or 70 mph. Suddenly, the vehicle will decelerate aggressively and violently causing any vehicles behind me to slam on their brakes to avoid a collision. This feature of the vehicle is not recognizing road signs, or other inanimate objects, correctly and mistakes them for some hazard that requires braking. Very dangerous.

Phantom breaking on my car, just like everyone else. In autopilot on the highway my car will break pretty hard when there is nothing in front of it. Seems to occur when approaching bridges and large signs. If I drive on the highway every day, it will happen to some degree at least once a drive. At least once this nearly caused an accident (I was almost rear ended because my car braked for no reason)

The contact owns a 2020 Tesla Model 3. The contact stated while driving 45 MPH and turning left, the vehicle experienced “Phantom Braking). There was no warning light illuminated. The vehicle was not taken to be diagnosed or repaired. Neither the dealer nor the manufacturer had been notified of the failure. The approximate failure mileage was 12,000

While driving down Interstate-5 my Tesla has been known to automatically brake from traffic safe speeds down to 40 immediately. It has happened multiple times. I have video to prove it as well. My video is too large at the moment but it does exist.

I have had too many phantom braking incidents to count, it has happened hundreds of times since I bought the car. Most incidents were mild slowdowns (3-10 mph) on some two lane roads through interstate and but some were quite quite violent, 20 mph or more slowdowns in a second or two. For example, using only adaptive cruise control or with autopilot also engaged and no other vehicles nearby, the car suddenly slammed on the brakes before I was able to step on the pedal and stop the deceleration. If there had been a truck behind me following close, it would have rear ended me. This sort of instance happens regularly, at least once or twice a week. Mild slow downs, as noted above, happen a handful of times most every time I drive the car. It happens when roads are empty or full, and slow downs also occur even...

The car braked from 65 mph to 35 mph with no obstructing traffic, the car has done similar things on many occasions however. On the occasion of the most recent occurrence, I noticed that the car indicated a change in the posted maximum speed for that location from 65 mph (normal highway speed) to 35 mph, at which time it began slowing to the erroneous 35 mph limit. There was no reason for the change in speed, as there was no posting, construction or traffic.

automatic braking happens for no reason. Happened multiple times on freeway .

On Tuesday 2/1/2022 approximately 9:20am EST, as I was sitting in a stop-and-go traffic, as the traffic was freeing up and started moving going roughly 5 to 10 mph, the vehicle automatically applied phantom brake - with a notification of emergency braking applied. I was not on cruse control or autopilot. i was in full control of the car yet it suddenly applied the ebrakes nearly causing someone to rear end me since the traffic had started moving.

Emergency braking kicks in at times when there's an oncoming vehicle in the opposite lane. It happens on straight roads in normal traffic when the oncoming vehicle is maintaining it's lane. The car will suddenly slam on the brakes when there's no chance of a collision. Afraid of getting rear ended, I avoid using the cruise control and "autopilot" due to this erratic behavior.

I read this morning that there have been complaints about the automatic emergency braking engaging when it shouldn't and I would like to add my car to the list. I've had my Tesla a little over two years and turned off the feature about a year ago because it would hit engage the emergency braking when there was no reason to. After a software update a month ago Tesla reactivated the feature without my permission and the only reason I knew it was activated is because the brakes slammed while I was on the freeway. The forward collision warning also activates often when there is no threat of collision of near by. The details below are an approximation of the last time the emergency braking engaged but this happened probably 4-5 other times during the year I had it activated.

I have experienced phantom breaking twice with my model 3. The first time was on the 101 freeway near Santa Clause Lane outside of Santa Barbara. There was no car in front of me or a hazard on the road but the vehicle made a sudden stop while I was traveling around 55MPH. The second occurrence happened on the 101 freeway near Santa Maria. Again, the vehicle made braked suddenly while traveling around 65MPH. The closest car in front of me was about 100 feet away. There was a car behind me but I was able to quickly hit the gas peddle to avoid an accident. I searched online at the time to see if anyone else had this issue but didn't have much luck. I'm thankful that I saw the Washington Post article.

Vehicle approached an upward slope which triggered a forward collision warning and (unsafe) emergency braking.

My car has experience phantom breaking issues since 1 month after purchasing in December 2019 when using autopilot. Each time phantom braking so far only happens during interstate driving. During the two year period, it has happened over 10 times. Fortunately, no vehicle was very close behind me when phantom braking occurs. Oddly, no forward collision warning occurred during the phantom braking.

Vehicle was driving on concrete-divided highway around 70 MPH. An ambulance with flashing lights came around a bend on the OPPOSITE side of the highway from the vehicle. Vehicle began to unnecessarily slow upon detecting the flashing lights.

There are two problems: (1) braking and (2) windshield wiper operation. (1) Braking: When driving on a highway and going by an on-ramp on the right side, without any warning, the vehicle would, al of a sudden, slam violently on the brakes, even though the cars entering the highway are nowhere near where I would be driving. This has happened repeatedly to me, creating a hazard of a rear-end collision. The Tesla Model 3 in such cases would already be in a mode that would drive itself (by me having clicked on the right stalk twice). Additionally, the car often misreads a traffic sign for a different part of the road, such as a stop sign for a side road. The violent braking would take place in such a scenario also. (2) Windshield wiper operation: I'm not sure if this would qualify as a safety issue, but the windshield wiper...

There is A LOT of phantom braking, not just on specific stretches of highway around Austin, but almost anywhere. There is a specific spot on US Highway 183 north in Austin where the speed is set at 65 and the Tesla M3 will rapidly brake without any warning. There is a danger of being rear ended. I manually disconnect the ADAS in anticipation. I shouldn’t have to. In general, phantom braking is dangerous and could be attributed to using vision only sensors?

Driving on Autopilot on a city street at 35 MPH speed limit, while passing next to a UPS truck parked on the right side of the street at the curb, but slightly protruding outside the parking lane, due to its size, my car sideswiped the parked UPS truck, causing scratches on my car and totally obliterating my passenger side mirror. My vehicle did not stop or try to veer away from the parked UPS truck, causing at a minimum $700 damage to my vehicle.

https://youtu.be/_vSGyqX0HZg My car is constantly running red lights when on "Full Self-Driving". They claim that it should stop at red lights but it very often confused the left turn red for the green in the straight lane. The car randomly serves at other traffic for no apparent reason. The car randomly slams on the brakes super hard for no apparent reason. Full Self-Driving is UNSAFE

AT A DRIVE THRU FAST FOOD TAPPED THE PEDDLE AND THE CAR LAUNCHED AND HIT A TRUCK IN FRONT OF ME

I BOUGHT A TESLA MODEL 3 ON 9/19/20. ON 9/23/20 I WAS WAITING IN MY CAR IN A LINE OF CARS AT A FAST FOOD DELIVERY WINDOW, STOPPED 8-10 FT BEHIND A LARGE VEHICLE WITH MY FOOT ON THE BRAKE AS WELL AS IN THE PARK MODE BECAUSE OF THE SLOW SERVICE AHEAD. AFTER A WHILE I REALIZED THAT MY TESLA HAD STARTED MOVING SLOWLY TOWARDS THE VEHICLE IN FRONT. PUMPING THE BRAKE, TRYING TO CHANGE THE GEAR TO REVERSE DID NOT STOP THE CAR. THE SCREEN DATA DISAPPEARED AND A MESSAGE FLASHED SAYING THAT ALL SAFETY FEATURES WERE OFF. I OPENED THE DOOR WHICH IS SUPPOSED TO STOP THE CAR. IT DID NOT EVEN AFTER I GOT OUT OF IT. IT CONTINUED TO MOVE EVEN AFTER CONTACT WAS MADE WITH THE CAR IN FRONT. THE TESLA WAS COMPLETELY CRUSHED. IT WAS A TOTAL LOSS ACCORDING TO A REPAIR SHOP...
