1 Automatic Emergency Braking problem

Failure Date: 07/01/2025

[xxx]- [xxx]am. Trying to park in ymca located in camp hill PA. Took soft right turn to park. Car accelerated instead of recognizing break, which I applied when I see it accelerating. Then I left break so it can take emergency break that didn’t happened it keep going and cross over the parking curb about six torah inch high and went in a ditch. I did not hurt but car front damaged. Tesla was informed and they have the log of the time but told they don’t see any issue. My insurance is paying all the expenses. This was the third incident where car did not tool emergency break itself or recognized the break. I did reported last incident to Tesla. It only happened three times in last six years.

2 Automatic Emergency Braking problem

Failure Date: 06/05/2025

* the aeb engaged when it shouldn't have. Yes. * yes * no. * yes, Tesla remotely told me that the error codes in my service menu had nothing to do with the aeb engaging when it wasn't supposed to. The problem has been reported to Tesla. * none. On [xxx] a car stopped suddenly in front of me and my aeb engaged when it shouldn't have. My car is a Model 3 performance and it can stop much faster than most cars. The car behind me came inches from hitting me and my dog and myself were thrown violently forward. This is a *major* safety hazard and could have caused an accident and has caused accidents in other cases. [xxx] this thread has videos of the incident. There was around 20 feet between my car and the car in front of me when the aeb stopped my car. My foot was already on the brake and I was in the process of stopping at a reasonable rate when the aeb suddenly engaged. I could feel the abs engaging. This happened another time about a month ago. A white box van two cars in front of me slowed down and turned right and the aeb engaged even though there was no need for it. Tesla has the ability to turn off the aeb but you have to do it each time you drive. Please require Tesla to make the aeb on/off choice sticky so you don't have to turn it off each time you drive. Also please make Tesla fix their software or disable aeb on their cars. Recent accident where aeb caused an accident. [xxx] other incidents where aeb engaged almost causing an accident or caused an accident: [xxx] [xxx] please do google searches to find the rest.

3 Automatic Emergency Braking problem

Failure Date: 12/04/2024

When cruise control or self-driving systems are engaged, there have been numerous times when the automatic emergency braking system mistakenly slowed the car suddenly. At 70+ mph, this is incredibly dangerous. The aebs apparently sees shadows as dangers. Fortunately, there has never been an instance when another vehicle has been close behind.

4 Automatic Emergency Braking problem

Failure Date: 02/29/2024

Thursday, 2/29/23 I was driving through a busy intersection. The car in front of me was slowing and I too slowed by gently easing the brake. This slow down was not unusual for steadily moving traffic. As my foot was resting on the brake, I felt the car pull the brake down below my foot hard, forcing my vehicle to abruptly stop and due to the force, my body was pushed into the steering wheel. No injury or accidents resulted however, if a car had been driving behind me, I would have been rear-ended. If my toddler had been with me, his car seat would have protected him but this would have been the greatest force ever placed on him. The car did not provide warning that the emergency brake would be activated. I am not aware of a publicly-notified defect at this time. I have scheduled the most soon appointment available with a Tesla service center in order to audit my software system with hope this glitch will be resolved.

5 Automatic Emergency Braking problem

Failure Date: 10/23/2023

The vehicle will randomly start emergency braking for no reason once so ever when using Teslas full self driving. This is extremely dangerous as it can happen at any moment while the autopilot feature is in use. In my most recent instance autopilot was set to 70 mph, and with no vehicles are traffic control devices present what is known as “phantom braking” started to occur. Which requires me to quickly reassume control of the vehicle and bring it back up to speed.

6 Automatic Emergency Braking problem

Failure Date: 07/13/2023

The brakes of my car did not work on July 2023. I stepped on the brakes and the car did not stop. It accelerated. I almost crashed into another car as the car kept on going. The car beeped when getting close to another car & slowed. I had to maneuver the car to the side of the road to avoid a collision. It did not stop until the length of 2 cars. My husband checked my Tesla car and saw there was an alert that the brakes did not work, however, he was unable to take a picture of the message and it did not re-appear. When I scheduled a Tesla service, at first it was a mobile service & they said it had to be checked at a service center. At the service center, I was told that nothing was wrong with my cars brakes and I was charged a $240 diagnostic fee. They state that they "test drove [the] vehicle and was unable to replicate customers concern. Using customers provided times stamp of 7/13/23 between 5:45 pm and 6 pm verified no brake related alerts where present. Technician inspected from and rear brakes, front and rear brake pad thickness was at 8mm. Customers stated about a recall related to loos brake caliper bolts, as of now there is no documentation available to service of any steps to take. For piece of mind technician torqued front caliper bolts to knuckled to 94nm and rear caliper bolts to knuckle to 83nm. Advise customer to monitor condition as it was a one time occurrence. " - component that failed were the brakes & the automatic emergency braking as it did not turn on quickly. - my safety was put at risk as I almost got into a car accident. - the Tesla service center at buena park "drove the vehicle and was unable to replicate" my concerns. - the vehicle was inspected by Tesla, but not by the police, insurance, representative or others. - there was a warning message that showed up when my husband went back to see if there were any messages and it stated that the brakes did not work. Of note, I do not recall seeing any messages before or during the incident.

7 Automatic Emergency Braking problem

Failure Date: 07/03/2023

Frequent phantom braking. If someone is following closely they may rear end us.

8 Automatic Emergency Braking problem

Failure Date: 05/07/2023

Recently I have been receiving warnings from my Tesla after hitting a pothole or bump in the road. Abs is disabled, power steering is disabled, power brake assist is disabled, forward collision warning and driver assistance features are all disabled. Upon a service visit to Tesla, they found that a fault within the abs sensor circuit triggers these faults until the car is parked and shuts off to complete a reset cycle. Tesla claimed that this abs cable was improperly placed and has caused damage to the sensor cable.

9 Automatic Emergency Braking problem

Failure Date: 04/22/2023

While driving, the aeb randomly and repeatedly activates while there are no obstacles in my path. It will slow on the interstate from 70 mph to 30 mph.

10 Automatic Emergency Braking problem

Failure Date: 04/10/2023

In autopilot or cruise control, this vehicle will brake unexpectedly with no vehicle or obstacle in front of it. This has happened primarily on highways, and it has happened between 10 and 15 times, such that now the driver cannot trust either autopilot or cruise control because if someone is following close behind, it could cause a wreck. We reported it to the dealer in wexford PA prior to a service appointment, and they have not been forthcoming with a solution. We do not believe they inspected the system. There was no warning that this failure was about to occur. Below I report the date of the last 3 occurrences.

11 Automatic Emergency Braking problem

Failure Date: 03/23/2023

On several occasions the autopilot mode braked unnecessarily. In one instance causing the big rig behind me to honk. Recently it braked hard when there were no cars around on the freeway. On a third time it braked as a car in a neighboring lane was close to crossing the lane but did not.

12 Automatic Emergency Braking problem

Failure Date: 01/17/2023

Vehicle came to abrupt stop so hard the seatbelt locked and my head hit the seat rest once fully stopped in highway traffic. I was traveling in the middle lane of a 3 lane highway at night, with clear skies, and dry road. There nearest car ahead of me was about 40 feet, and I was traveling with the flow of traffic at around 20 mph. “autopilot” was enabled and set to 35mph. I believe the adas camera system of my vehicle momentarily determined a nearby car in the left or right lane had suddenly moved into my lane when in reality none had crossed the white line and the road ahead was clear.

13 Automatic Emergency Braking problem

Failure Date: 01/12/2023

I was utilizing Tesla's self-driving feature and while traveling at about 75mph, the vehicle slammed on the braked on three different occasions for no reason. Fortunately, on all occasions, no vehicles were anywhere near me. There were no warning signs and this is the first occurrence. I have not utilized cruise control or the self-driving function, since.

14 Automatic Emergency Braking problem

Failure Date: 11/24/2022

Was using autopilot feature on the vehicle on thanksgiving. Was going about 75 miles per hour when suddenly autopilot failed and the car lost control. I had to quickly regain control of the vehicle before I crashed. I took photos of the error messages and reported the incident to Tesla via the Tesla app. Typically autopilot fails gracefully and provides notifications. I’ve never seen it fail with no warning and loss of control of the vehicle.

15 Automatic Emergency Braking problem

Failure Date: 10/23/2022

My handicap son, devdutt srivastava, on cushing parkway and fremont boulevard. Fremont, CA, on us October 24 evening with no auto pilot or fusd engaged. At threshold the light had turned orange and my son proceeded with same pace as usual, without accelerating. A cross car with an autistic kid, most likely as my son is a special ed masters and trained to spot one, rammed into the Tesla 3 which was fully wrecked. The auto collision emergency detection and braking should have worked as it was stop and go traffic at peak evening hours between 3:50 and 4:30 pm. I have seen Toyota prius auto collison braking work. Someone needs to stop elon musk and Tesla charging premium on false promises and taking toll on lives of innocent people trusting their marketing false propoganda and constant spinning on auto pilot and fud with new additional confusion creating packages and options and moving features too and fro. This complicates the software and causes more bugs.

16 Automatic Emergency Braking problem

Failure Date: 10/10/2022

The contact owns a 2019 Tesla Model 3. The contact stated while driving approximately 70 mph with adaptive cruise control mode and passing a semi truck, the vehicle experienced phantom braking and pulled hard to the left on three occasions. There were no warning lights illuminated. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and advised the contact to provide a two minute time frame of the next occurrence of the failure. The failure mileage was approximately 27,019.

17 Automatic Emergency Braking problem

Failure Date: 09/21/2022

It has happened twice already today 9/21/22 was the second time that happened I was driving in the highway and the Tesla suddenly hard brake with no cars near me if this problem continues it could lead to future accidents if someone is following to close….

18 Automatic Emergency Braking problem

Failure Date: 09/18/2022

I experienced more than 10 incidents of “phantom braking” while on interstate highways (i90 and i29) on a round trip from solon iowa to western south dakota. ( late Sep 2022). There were no apparent obstructions, nearby vehicles, or other dangers. In several incidents I was traveling at the speed limit (80 mph) and the car braked so suddenly and hard it jolted wife and terrified her. If a car or truck was behind me I would have almost certainly had a serious accident. This behavior seems to have gotten much worse in the past few months, although I have seen it occasionally over the 3 years (48000 miles) I have owned the car. I have noticed it happens most often near the crest of hills.

19 Automatic Emergency Braking problem

Failure Date: 09/01/2022

Broken control arms.

20 Automatic Emergency Braking problem

Failure Date: 06/14/2022

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in full self-driving beta 10. 12. 2 mode. The vehicle was travelling at 21mph approaching a railroad crossing in moderate to busy traffic. The crossing was open. The Tesla slowed quickly to 7 mph for no reason. The driver had to take control of the vehicle in order to maintain progress and not cause a hazard to other road users. A link to the incident can be found below: https://vimeo. Com/729934579/b3e3d6438a.

21 Automatic Emergency Braking problem

Failure Date: 06/11/2022

I was driving on Tesla “autopilot” and instead of noticing the exit from freeway , the car thought it was still on freeway as it had to take the next exit, it just on full speed went into the exit, it did not break or slow down and just before the sharp exit turn on 65 mph it just disengaged autopilot with message “system error “ luckily I was aware and was able to avoid a major crash . If I was a second late, the car would have gone through the road barrier. I’m sure if I had a crash Tesla would find reasons to blame me for the crash even though it was its software. Autopilot is junk piece of software with little regards to customer safety. I am not sure how something like this is even allowed to be sold and used on public roads.

22 Automatic Emergency Braking problem

Failure Date: 06/09/2022

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in full self-driving beta 10. 12. 2 mode. The vehicle approached a stop sign ahead of a single lane bridge at 14 mph. The vehicle braked and left the road coming to a halt on a private driveway. In fsd mode the vehicle attempted to approach a metal gate. The driver had to disengage fsd mode to safely manoeuvre the vehicle. A link to the clip of the incident can be found below: https://vimeo. Com/730266676/f170446e7d.

23 Automatic Emergency Braking problem

Failure Date: 06/09/2022

The contact owns a 2019 Tesla Model 3. The contact stated while driving 70 mph, the forward collision avoidance: automatic emergency braking was disabled independently. The contact stated that the forward collision avoidance warning light was illuminated. The vehicle was driven to work safely. The vehicle was not repaired. The dealer and the manufacture were informed of the failure. The failure mileage was 89,050.

24 Automatic Emergency Braking problem

Failure Date: 06/01/2022

When I drive under bridges during the daytime, the vehicle will alert and in many cases brake the car. Can be very repeatable in my experience on my commute. Has happened on nearly every single different software version I had on the car over the last several years. Used to always report the 'bug' to Tesla but they never did anything about it.

25 Automatic Emergency Braking problem

Failure Date: 05/18/2022

Multiple occurrences of phantom braking while at highway speed and using autopilot (I do not have fsd). In most cases, there is another car (on either side next to me) and a 3rd car is coming up from behind at a high rate of speed. The 3rd car then cuts across to the open lane and as that's happening, my car suddenly/abruptly applies emergency braking and I instinctually apply throttle to keep the car moving forward. I have submitted bug reports to Tesla at the time of each incident.

26 Automatic Emergency Braking problem

Failure Date: 04/12/2022

The contact owns a 2019 Tesla Model 3. The contact stated that while driving at 60 mph, the vehicle experienced phantom braking while there was no other vehicles or objects around. There was no warning light illuminated. The contact depressed the accelerator pedal and was able to continue driving. The contact stated that the failure had been reoccurring increasingly while driving. The contact stated that the vehicle was not designed with self-driving mode. The manufacturer was notified of the failure but provided no assistance. The vehicle was not diagnosed or repaired. The failure mileage was approximately 50,500.

27 Automatic Emergency Braking problem

Failure Date: 03/20/2022

The scenario mentioned has happened numerous times. When using autopilot on a two lane highway, the vehicle's aeb kicked in and slammed on the brakes multiple times. My theory is that since ditching radar, the vehicle thinks that the oncoming traffic is coming into its current lane even though there is a set of double yellow lines dividing it. This phantom braking issue is especially prevalent when there are curves in the road, as momentarily it may appear that oncoming traffic is "head on". This resulted in me almost getting rear ended by the vehicles behind me and causing a multi-vehicle accident.

28 Automatic Emergency Braking problem

Failure Date: 03/19/2022

The vehicle suddenly and without visible obstruction in the road and with out warning applies the brakes aggressively which decreases velocity in an unsafe manner. This occurs while the enhanced autopilot is active. The component has not been inspected by the manufacturer, police, insurance representatives or other. The only prior warning is that the aggressive braking has occurred on several occasions as early as 2019. The most recent occurrence was on 03/19/22.

29 Automatic Emergency Braking problem

Failure Date: 03/16/2022

Autopilot break the car for no reason on highways and high speed. Always happen on I-5 at anaheim, CA to los angeles, CA area.

30 Automatic Emergency Braking problem

Failure Date: 03/13/2022

While driving with Tesla auto-pilot enabled, the car experiences phantom braking. This has happened multiple times already. The car will break unexpectedly for no good reason even if there is no obstruction on the road. The problem typically happens in the freeway at high speeds and presents a huge safety risk to the car occupants and the car behind since it increases the risk of a rear end collision. The problem is pretty common, a simple search on internet of Tesla auto pilot phantom braking will yield many results. The problem started getting worse after full self driving beta was enabled around January 2022. When the problem happens, the car beeps loudly and breaks really hard.

31 Automatic Emergency Braking problem

Failure Date: 02/23/2022

While driving along the interstate on my commute at freeway speeds 60-70 miles per hour, the emergency braking system will suddenly engage, and the car will issue a collision warning. During these incidents there is no car at risk for striking my vehicle or slowing down in front of my car. My commute usually occurs in the evening and early in the morning. This typically happens at least once during my work week.

32 Automatic Emergency Braking problem

Failure Date: 02/22/2022

Tesla has charged $6000 for delf driving 2 years back and the self driving just came in effect , it is really risky to use this as the car brakes right before exit and some times does not evn recognize the red light s.

33 Automatic Emergency Braking problem

Failure Date: 02/13/2022

I start noticing when you stop at stop light or traffic light and soon you start drive and before it’s get speed it’s break for second you feel and notice something stop for second and this start happening since last 10 days.

34 Automatic Emergency Braking problem

Failure Date: 02/08/2022

While in Tesla’s auto pilot mode, the vehicle breaks for no particular reason. This is particularly very dangerous while going 70 mph and someone is following in close proximity. I have gotten side eyes and hand gestures from fellow motorists, I presume it is due to them thinking I break checked but I am very defensive driver and I would not put anyone at risks for any reason. I got rear ended back in 2019 in slow speed but do attribute this to Tesla sudden breaking issue. I have since stop auto auto pilot in regular basis. I do use auto pilot once here and there often in light traffic.

35 Automatic Emergency Braking problem

Failure Date: 02/04/2022

While driving with autopilot engaged (adaptive cruise control + automatic braking) the vehicle abruptly slams on the brakes even when there is no vehicle or objects in its path.
