2019 TESLA MODEL 3 Forward Collision Avoidance Automatic Emergency Braking Problems

Vehicle: 2019 Tesla Model 3 Dual Motor VIN: [XXX] Mileage: ~84,041 Software: v12 (2025.32.6 e575ed98d527), FSD Supervised v12.6.4 Date/Time: [XXX], ~[XXX] Location: [XXX] Incident Description: While operating Autopilot, I was stopped at a stop sign preparing to turn right. I lightly pressed the accelerator to prompt the turn. At that moment, the vehicle would not respond to steering or braking input. Despite applying full force on the steering wheel and brake pedal, the car continued straight ahead and struck a street sign. This represents a loss of manual override — I was completely locked out of steering and braking. Prior Behavior at Same Location: On prior occasions using Autopilot at this same intersection, the vehicle would attempt to make the turn but then immediately steer itself into the breakdown lane. I had learned to expect this and was prepared to take over. However, in this most recent incident, the vehicle...

[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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

* 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...

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.

It brakes at highway speeds of 70 without reasons on cruise control and FSD. Happened three times on highway 46. It can be very bad if there was a car behind me. This happened to me through all these years since 2019.

I’m at the Tesla service center and Tesla is refusing to perform recall work without payment/diagnostic time. Even though Tesla’s website and notices states that they will perform recall work free of charge they are in fact refusing to perform recall work free of charge. They are mandating that I be charged diagnostic fees for them to determine whether they will perform the recall work as of 11/13 at 7:15am per Marc the service advisor at Tesla Service Center Kearny Mesa.

Tesla Model 3 with FSD (Full Self Driving) package. Engaged FSD to drive home today but vehicle failed to recognize ALL traffic control signals (stop signs, red & green stoplights. The first time this occurred, I had to brake emergently to avoid collision with cross traffic that had a ‘green’ light. Subsequently reactivated FSD to check the issue and vehicle attempted to run several more red lights and stop signs.It did, however recognize and stop for stopped traffic ahead and performed fairly well with autosteer. This is the first time we have had this potentially-fatal issue. We have, for several months had an issue where some or all of the Tesla cameras fail intermittently. This usually happens at the beginning of a drive and the vehicle alerts us ‘Automatic braking temporarily unavailable.’ Sometimes it recovers on a subsequent drive the same day and rarely recovers on same drive. When cameras...

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...

Tesla has combined cruise control with their Auto Pilot feature. Now there is no human override to what speed limit to use, Tesla determines the speed to used based on certain criteria. This puts the driver at risk who may want to lower or increase the speed limit based on certain conditions Tesla may not be able to detect. For me it was a 9 PM run to the store thru an area that had temporary road construction and known to be a speed trap zone.

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...

Ever since Tesla updated my vehicle to 2023.44.30.8, the autopilot has become effectively unusable. It now nags and beeps at me whenever I am not looking straight ahead. It is ridiculous that Tesla has ruined one of the best aspects of my car due to (ostensibly?) NHTSA pressure. Please allow their previous driver attentiveness system with the steering wheel to be reinstated. It is so miserable to have my car nanny camera flip out on me every time I look anywhere other than straight ahead. At the very least, every other manufacturer should be forced to have just as annoying a system if my Tesla had to be ruined. Its wrong to punish every Tesla owner because some people misused autopilot.

Vehicle experienced phantom breaking previously documented for Teslas. The vehicle suddenly decelerated by 22mph from 75 to 58 mph in approximately 2 to 4 seconds while cresting a hill on an interstate and navigating on autopilot. There were no vehicles or objects ahead of the vehicle. There was one vehicle behind at an indeterminate distance at the start of the phantom breaking event. The driver had their hand on the wheel before the initiation of the phantom breaking and the autopilot system alarmed and prompted the driver to take control at the onset of the phantom breaking.

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.

I experience frequent "phantom" braking while driving north or south on highway I-75. Many times this happens near state route 70 traveling north, but I have had this phenomenon happening driving south or headed north on 275. Cruise control is on, autopilot may or may not be on (I have had it happen in both modes). It's a frightening and very dangerous problem. Speeds decelerate from 75 or so to about 35 or 40. It's sudden and scary and potentially life threatening. I have immediately hit the gas in the multiple times this has happened.

Traveling west in I8 between Gila Bend and San Diego I experienced over 20 automatic hard braking events while using TACC. The road was clear, there were no vehicles in front of me within 400 yards. It appeared to be correlated with heat mirages on the road surface ahead though some may have been caused by differences in asphalt color in sections. The hard braking occurred at highway speeds of 70-75mph and dropped my speed rapidly, if a car or truck had been following me closely it could have result in an accident. The remedy is to press the accelerator to resume speed. Training drivers to hit the accelerator in response to phantom braking events is also dangerous as the automatic braking might be overridden automatically by a driver when there really is an event that calls for emergency braking. When the false positives out number to true positives by...

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

Driving on a clear, sunny day in Arizona on interstate 8 at highway speed with the Tesla AutoPilot engaged. There were no vehicles in front of me and no obstructions in the road when the car did heavy braking (aka phantom braking) for no known reason. I immediately had to override the braking with pressing on the accelerator. This occurred multiple times on the same road. If a vehicle had been traveling behind me when this happened, it would be highly likely that a collision would occur because of the random nature of the extreme braking. I did not use the adaptive cruise feature the rest of the trip in fear that a collision would occur. No warning messages were/are present. The Model 3 I drive is equipped with sensors on the front bumper that (I believe) Tesla has deactivated to use vision-only instead. I drove for years using the...

The contact owns a 2019 Tesla Model 3. The contact stated that while utilizing the ADAS features including the Adaptive Cruise Control, the vehicle unexpectedly braked. The contact stated that on another occasion while the accelerator pedal was depressed, the vehicle experienced phantom braking. Due to the failure, the vehicle abruptly stopped and caused the contacts wife’s seat belt to retract very tight. The contact stated that he disengaged the features including the Adaptive Cruise Control to operate the vehicle. The vehicle was taken to the dealer where it remained. No warning lights were illuminated. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 50,000.

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.

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.

On long, straight interstate highway roads where speed limit is 80mph in GOOD to EXCELLENT weather and visibility conditions the vehicle on average would apply emergency braking at least 10x per 1,000 miles when no hazard or obstruction was present. This was often caused by asphalt color changes, slight hills, or shimmer in the distance…all of which are normal conditions for average driving. If vehicle was being followed closely by another car it had potential to cause high speed collision and injury or death.

The contact's girlfriend owns a 2019 Tesla Model 3. The contact stated while driving 73 MPH with the Adaptive Cruise Control activated, the vehicle experienced phantom braking. The contact stated no warning light was illuminated. The vehicle was not diagnosed or repaired. A dealer was not contacted. The manufacturer had not been informed of the failure. The failure mileage was approximately 41,000.

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.

My car restarted itself and wiped out the entirety of my saved settings. I’m very upset because I had to set up everything all over again. Additionally, the full self driving brakes randomly while driving and causing my body to slam and pushed back from the seat belt. The autopilot feature also failed to recognize yellow lights where it will cross it, which had to be disengaged by the driver in order to avoid accident. The fsd also failed to recognize merging lane when merging onto the freeway.

I have six recorded incidents over three different trips where I was traveling at highway speeds on I-84. While utilizing cruise control, weather was clear and roads were dry with no vehicles in front of, behind or to the side of me. The vehicle slammed on it's brakes unexpectedly and for no apparent reason. 5 out of the 6 times, it stopped so fast, nearly coming to a complete stop that it caused the vehicle to swerve almost out of control. Luckily there were no vehicles close behind me, otherwise I would have certainly been rear ended and possibly even killed at the speeds we were traveling. I have spoken to Tesla and they admit it is a known problem, but they don't have an immediate fix. The recommend not using cruise control in their vehicles. I think they should buy the vehicles back if you cannot use something as...

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.

Tesla knowingly disabled the hardware sensor suite in a recent update of the software in their push toward "Tesla Vision". Unfortunately the disabling of the hardware sensor suite has made the car more dangerous to drive in certain conditions such as dark roads and inclement weather where the camera cannot detect a danger situation in advance the way it could with a hardware sensor suite. The disabling of this sensor is costing me $6000 in damage due to Tesla Vision not seeing a large, dead deer in the middle of the highway causing me to drive over it and damage critical components. Tesla's decision to use a plastic shield instead of a metal shield to protect the components lead to the piercing of the battery coolant line and damage to other components.

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.

Since disabling the radar, the car very frequently brake checks on the highway when there are no cars in front of it, due to the reflection off the surface of highways that are very flat. This happens at least every hour or 2 when driving.

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...

12/24 between 7:54am and 8:55am driving on the 10 west from Arizona to California while on auto drive within one hour experienced 4 times the car engaged the brake while traveling 80 mph on the highway. All 4 times there was nothing in front or side of the vehicle. The vehicle did not alarm a sensor that something was in the way. Fortunately we reacted quickly and continued with the accelerator so we didn’t stop abruptly on the Highway. 2 out of the 4 times it was a very hard brake the other two times it was hard but not nearly as forceful. Again nothing in the road, sun behind us, no indicators of obstructed cameras. We haven’t been on a long trip with the car in a long time, however my son drove from Orange County , CA to Los Angeles one evening about 6 weeks ago and he...

"Full Self Driving" (FSD) 10.69.3.1 disconnect events lock out driver after five 'strikes.' This makes it impossible to diagnose repeatable faults until a future version unlocks FSD. My testing suggests there are problems with controlled intersections making a left turn. However, the lockout prevents documenting the problem(s). Locking out the software also makes it impossible for NHTSA, IIHS, and even the National Transportation Safety Board to identify and document failures with FSD. It also impacts car reviewers as well as this owner.

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.

The contact owns a 2019 Tesla Model 3. The contact stated while driving 65 MPH, the vehicle experienced "phantom braking". The contact stated no warning light was illuminated. The contact was able to continue driving to his destination. The contact informed the manufacturer of the failure through the Tesla App and the mobile service unit was dispatched to inspect the vehicle. The vehicle was not repaired. The contact stated that recently he had experienced the failure five times within an hour and a half. The manufacturer had been informed of the failure. The failure mileage was approximately 21,100.

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.

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.

On a recent cross-country trip in our Tesla, we experienced "phantom braking" a number of times when we had the adaptive cruise control engaged. We were not using more advanced features on any of these occasions.

While the vehicle has adaptive cruise control engaged, there are times it applies braking (sometimes aggressive braking) for no reason (commonly referred to as phantom braking). It’s almost as if the vehicle thinks there is an object in front of it and is applying emergency braking, however there is nothing on the road. In my experiences, it happens mostly on the Highway at speeds 60-80mph. This happens on clear days, with no weather concerns. This is a severe issue that will cause accidents (if people are following closely behind me, there is a concern of them hitting me). It is scary and concerning ; this needs to be immediately addressed and corrected.

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.

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…

Broken control arms

I have experience phantom braking on my Model 3 many times when I used FSD(full self drive) on the freeway. The car just randomly slows down / decelerates abruptly even if there are no obstacles or other cars in front. This results in a serious situation when the vehicle behind may ram into you causing a fatal accident. I have always reported this issue using voice control REPORT BUG and got acknowledgement saying THANKS FOR THE FEEDBACK. But I have never heard from Tesla that they have fixed or are fixing it. This issue is happening almost every time I used FSD on freeway even today (Aug 30, 2022)

1. Phantom braking while on autopilot in a freeway (I15, I215, etc) 2. Disengaging auto pilot when it is making a curve in a freeway to another freeway (San Diego freeway)

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. Whilst travelling at 24mph the FSD informs the driver to “avoid traffic cones” and brakes to 12mph for no apparent reason . The video of the incident clearly shows there were no traffic cones to avoid. The vehicle automatically disengages from FSD mode whilst crossing an intersection, creating a hazard for other road users. A link to the clip of the incident can be found below: https://vimeo.com/730258398/e0f8b28291

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

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

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 Tesla was in traffic waiting to turn left at an intersection. As the vehicle made the turn it decelerated from 18mph to 10mph at a secondary red light - 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 clip of the incident can be found below: https://vimeo.com/729935224/032493c7fd

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

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 manufacturer were informed of the failure. The failure mileage was 89,050.

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.
