2023 TESLA MODEL 3 Forward Collision Avoidance Automatic Emergency Braking Problems

The vehicle’s brakes did not work, automatic emergency brakes and collision warning both did not work. I pressed on the brake for about 5 seconds but the brakes did not work, resulting in a collision with the car in front. Everything is available for inspection if needed. Both my safety and the driver of the vehicle in front of me was at risk. The problem has not been confirmed yet. The vehicle is currently at a shop, waiting inspection. There were no warning lamps, messages, or symptoms.

On August 7th, 2025 at around 8 AM in the morning, my vehicles mobile phone car key was in-operable and I was unable to get in the car which led me to trouble shoot how to fix this issue with the car. Upon researching I was directed by Tesla to directly complete a soft reset of the vehicle holding down both buttons on the vehicle once I was inside, and pushing on the brake pedal. Upon completion, my vehicle booted up and I realized that all camera systems were down, my navigation systems were down, my safety features were down, my auto pilot, lane keeping assist and auto brake were down, sensors were down and I was no longer able to pre heat my battery to charge my vehicle due to issues with the navigation. I then took the vehicle to Tesla Service Center Irvine where a service advisor quoted...

During driving, Tesla car spontaneously stated multiple active safety features and regenerative braking were no longer available and stopped working during driving with multiple warnings appearing. Driver safety at risk during this as well as others safety due to the lack of functioning. The car was taken to Tesla service center and was explained that front lower lateral suspension links were damaged by "impact" although the car was never in an impact or accident preventing proper alignment and functioning of the car. The part has been since repaired and currently undergoing further investigation for warranty dispute.

Autopilot (adaptive cruise control) will freak out and slam on the brakes when a motorcycle passes by splitting lanes. This is a serious safety issue as cars and motorcycles behind me may not be able to react in time and cause a rear end collision or into the wall or vehicles next to them. It is impossible to override the braking with the accelerator as it will be too late by the time the car accelerates. Flooring the accelerator is also not a safe option.

My Tesla Model 3 disengaged cruise control while going 68 mph and braked hard for no apparent reason. I was driving northbound on I-405 at 3:45 a.m. going to LAX airport in the number 3 or 4 of six or seven lanes. Cruise control had been activated for at least 10 minutes before the incident at a speed of 68 mph. There was no traffic within half a mile before or after me due to the time of day. Neither my left or right foot were near either the brake or acceleration pedal, nor were they in motion. Both hands were on the steering wheel and no control was being activated. The only noticeable environmental condition is that the road surface had just changed from a dark gray asphalt to a bright white new concrete roadway. No emergency braking alert was seen or heard, so I do not think it...

The contact rented a 2023 Tesla Model 3. The contact stated that while driving at 55 MPH in the rain, a vehicle in front of him abruptly slowed down. The contact depressed the brake pedal, but the vehicle jerked to the side. The contact stated that the emergency braking system unexpectedly activated ("slams on") while he was driving due to the Automatic Emergency Braking (AEB) system falsely detecting a potential collision. There were large rocks in the roadway, and there was no traction, causing him to crash into an embankment. The driver's side airbag did not deploy. The other airbags in the vehicle had deployed. The contact sustained a fractured rib, and medical attention was provided at the hospital. The vehicle was towed to a towing company. There were no reported fires. A police report was filed. The local dealer was not contacted. The vehicle was not diagnosed or repaired....

Description of Problem: While driving under normal highway conditions on July 2, 2025, my Tesla suddenly and violently phantom braked — meaning it rapidly and without cause applied the brakes forcefully. There were no obstacles, vehicles, or hazards present. The sudden deceleration caused a severe flare-up of a recent cervical disc replacement surgery I had undergone. I experienced extreme neck and spinal pain and had to seek emergency medical attention. I am now under medical supervision, on pain medication, and unable to work. I contacted Tesla requesting the logs from the incident and have received no response. I’m deeply concerned about the safety of this vehicle and the lack of accountability for this known and previously investigated issue. I am in the process of retaining legal counsel and intend to pursue this further as a product liability and injury case.

While driving with the Adaptive Cruise Control enabled, on California highway 5 on Aug 28, 2023, the vehicle applied the brakes very aggressively and suddenly, shy of making a complete stop, without any object or shadow requiring it to do so - known as the "Phantom Breaking". It was so dangerous that if it was a weekend with many cars behind me, I would've been violently rear-ended and perhaps not lived to report this incident. This happened twice in two hours, to the point that I have never engaged the cruise system again. The Adaptive Cruise Control (ACC) system (which is part of the Auto Pilot system) on this vehicle is dangerous and should be avoided. I wish the vehicle had the [old fashioned] non-adaptive cruise control but it doesn't. Answering the questions: Nothing failed but the ACC clearly malfunctioned since there was no object, shadow, road animal, change in...

Curvature Assist feature agressively brakes while driving at highway speeds. This is supposed to slow down for curves, but frequently intervenes for straight, clearly marked lanes. Feature cannot be turned off. Drivers behind me have gotten agitated several times for the sudden, harsh braking, and I do not feel comfortable driving this car.

I was traveling at highway speeds on a highway with no vehicles or other obstacles in front of me. I had adaptive cruise control on. Then, the emergency brakes deployed for no reason (so called “phantom braking”), decelerating the car quickly. I turned off adaptive cruise control as fast as I could and nothing bad happened. But the situation was dangerous, as if a car was close behind me it could have rear ended my vehicle.

Software updates caused failure notifications (seat restraint system) and disabled cameras/emergency brakes, happened immediately right after software updates. All hardware performed and properly functioned before the software updates. 1. First failure noticed on the begin of March 2024, component affected : " Rear center safety restraint system fault". Second failure noticed on [XXX] component affected: " Autopilot cameras unavailable", "Automatic emergency braking is unavailable" 2. I feel extremely unsafe now when using the vehicle with failure notification of the car's components, especially while driving my children to school. I am unsure if the system failure that could causes accidents and put my kids at risk or danger. 3. First issue was notified Tesla representative immediately right after the software update (happened over night). They scheduled an appointment, but I saw a charge bill that I have to approve before taking the car in for an inspection. It happened when my...

If a Tesla software update fails it causes an APB version mismatch causing all safety features to become disabled until you schedule service for repairs. It is not covered outside of warranty even though it’s an issue caused by their update. If you google APB Version Mismatch, a lot of people have experienced it. Out of warranty repair is $2-3k for a computer replacement even though it was working fine before the update.

Brake Feature Malfunction Vehicle Details: •Model: Tesla Model 3 •Year: 2023 (approximately 1 year old) •Mileage at Incident: ~11,000 miles Incident Description: On 10/29, while manually driving my Tesla Model 3 on a public roadway, I experienced a critical braking failure. As I approached a vehicle in front of me that was decelerating, I initiated regenerative braking, then immediately applied the brake pedal forcefully. Despite pressing the brake pedal hard multiple times, the vehicle did not decelerate as expected and ultimately collided with the vehicle ahead. Throughout this incident, no collision warning, automatic braking, or other safety features activated, despite having all safety features enabled. This failure significantly impacted my confidence in the vehicle’s braking and safety systems. After the accident, I reviewed the Tesla incident report, which shows I attempted to brake but that acceleration was not reduced until the collision occurred. Despite the report documenting my attempts to...

The system failed to detect the driver having a seizure and had no way for the passenger to break the vehicle. People in the vehicle and Others were put at the risk of a seizing person accelerating in a car that could not be prevented by the car or by the passenger. No dealer/service center has confirmed the issues. The vehicle is currently being inspected by police. No known warning signs/messages before the incident.

The contact owns a 2023 Tesla Model 3. The contact stated that while entering a parking lot, the brake pedal failed to respond, the driver was unable to control the steering wheel and crashed into a Ford vehicle and a tree. The air bags deployed, and the vehicle stopped shortly after. The forward collision emergency braking system failed to engage. There were no warning lights illuminated. The vehicle was towed to a tow lot. A police report was filed. There was no reported fire. The contact sustained injuries to the neck and shoulder and had bruises. Medical attention was provided. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 12,166.

While using standard cruise control (without autosteer), car sporadically & aggressively brakes for no reason with no obstruction or cars ahead and while at highway speeds. With cars close behind, a serious, life-threatening accident could've occurred. Can not determine how to recreate issue on demand. This is a known issue with Teslas that has not been addressed by Tesla. I have not reported this issue to Tesla.

On [XXX] around [XXX], my daughter drove her Tesla Model 3 on [XXX] from school. Two strange/scary accidents happened to two different Tesla cars (Model 3 and Y). It was raining with low/medium visibility. One of the cars was driven by my daughter, and luckily, both drivers were safe with very minor injuries. The cars had significant damage but were drivable, and there were no airbags out. These two accidents occurred within 3 to 5 minutes at the “SAME LOCATION.” When I asked them what happened, my daughter and other Model Y drivers described a sudden loss of control, with their cars spinning and becoming unresponsive to steering and braking. They then hit the guardrail on the center line. I checked the video recordings of our car multiple times; no vehicle-to-vehicle collision was involved. I also checked the road to see if there was any oil spillage, but the lane...

On [XXX], I was driving my Tesla model 3 from California to my new home in Idaho as part of my move there. During the day, I had 6 or 7 situations where the car would suddenly go into full regenerative braking, or outright apply the brakes for no apparent reason. Most of these events took place of freeways at freeways speeds, or on highways (not freeways) at the local speed limit. Every situation was when I had supervised self drive or traffic aware cruise control enabled. These situations were extremely startling and in my opinion potentially dangerous. I don't want to imagine what might have happened if one of these "phantom braking" events had occurred with a heavy 18 wheeler behind me in traffic. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When using cruise control, my 2023 Tesla Model 3 will aggressively brake without warning or apparent cause. The braking is near maximal - as though the vehicle is attempting to prevent an imminent collision. This defect poses a hazard to occupants of vehicles behind mine as well as myself and my passengers as sudden braking could cause a rear-end collision and cascading loss of control. Inclement weather would have exacerbated the problem. This problem is documented. From my brief research it appears Phantom Braking has been the subject of a NHTSA investigation previously but for prior model years. The issue persists. When I questioned Tesla Service regarding this life and limb threatening problem their staff was aware and well versed at requesting the customer report the issue as though it were a minor software glitch. This is a significantly more serious problem necessitating an appropriate response.

I was driving behind someone when a suv came over from left lane into the right lane in front of the cars that were in Front of me and made a sudden turn into a business. I was already applying the brake and was the 3 second rule behind the car in front of me, however the car did not stop as I slammed on the brakes as hard as I could. There have been other times that the car will automatically slammed brakes on because it feels that it need to…when it’s not necessary at all. But the other day when I needed the brakes to help me stop abruptly…they failed to do so. I hit the car in front of me and was cited as well. If I had been going faster..this could have been way worse. This definitely needs to be evaluated on Teslas. I have a...

Driving normally down I-5, no other cars nearby and system suddenly phantom brakes. I am lucky no other cars were behind me as it may have well caused an accident. There were no other cars in front of me within at least 1 mile.

Back in February my Tesla Model 3 started acting up Emergency Brake was disabled, automatic vehicle hold was disabled, and traction control was disabled all issues I reported to the company app with photo. This problem stated when a software update happened after the Tesla app requested it.

As I was approaching my off ramp (which has a very tight turn), my automatic brakes failed which caused me to slam onto the brakes, and skid into one of the off ramp signs. All 3 of my children were in the back, the back driver side window shattered, I lost my driver side mirror, and there was damage done to the back door and wheel well (all on the driver's side). Although the damage looked minimal, no one was willing to work on the vehicle and I was strongly encouraged by my insurance company to claim it as a total loss. Granted, I had this vehicle for approximately 2 months, and had put at least $4,000 into it.

On Jan. 1, 2024 at around 2:19-2:20PM, the vehicle in front of me made a sudden brake causing my vehicle to trigger the Automatic Emergency Brake. My foot was on the brake pedal as well, I even floored the pedal to make my car stop right away but it continued anyway, the pedal felt so loose/soft. My car almost made a full stop but when the vehicle in front of me started moving, the car started to somehow accelerate, I was confused as to why the car was moving when my foot was firmly pushing the brake. This unexpected move caused me to rear-end the vehicle in front when they abruptly stopped for the second time. My thought is since the car in front moved, the Tesla thought the vehicle in front was no longer a threat and stopped applying the brake to make a full stop. I watched a...

Driving down the highway on a clear day with nothing in front of me, with adaptive cruise control turned on, the car suddenly started braking as if it was in full regen braking. I had to hit the accelerator pedal to override the braking.

Autosteer was engaged while approaching Weatherford, OK on I40 - Sporadically, the vehicle slammed on the brakes, even though nothing was in front of me, and nothing was behind. The vehicle dropped in speed by almost 20 mph.

vehicle auto stopped in the middle of the parkway

Random phantom breaking when using cruise control at high speeds. Goes from 70-40 mph and always worried someone is going to rear end me when my car automatically rapidly slows down for no reason. Huge hazard and risk!

Driving North/East on Highway 87 at 1215pm, kind of into the sun (Sun was to the right of us), the car would not maintain cruise control without constantly applying the brakes forcefully. No cars in the immediate vicinity during the event, though there were other cars on the highway at the time. Returning south on the same road, about an hour later, no issues whatsoever.

As part of transitioning from radar to a camera based system (this affects model years '22 onward), Tesla, has "temporarily" disabled key features such as lane departure, blind spot alerts and emergency braking. Though disabled, these features are still selectable (not greyed out) when the user chooses safety options. These features, which are available on most modern cars, have been disabled for many months with no committed date to restore functionality ... this poses a major safety risk. This should impact Tesla's NHTSA safety rating which will pressure the company to re-enable these basic safety features ASAP. Thank you.

Phantom Breaking when in adoptive cruise control

The car lost all adaptive driving features and power steering.

The contact owns a 2023 Tesla Model 3. The contact stated while driving at various speeds with the cruise control activated, the vehicle experienced phantom braking. The vehicle was diagnosed by a mobile application where it was diagnosed that the firmware needed to be updated. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 4,000.

Will Randomly slam on the brakes saying that there is something in front of cars on the highway. This has caused me to almost get into a few accidents suddenly slamming on the breaks at 75 mph. It has happened numerous times and the car feels unsafe to drive. One example it slammed on the brakes in front of an 18 wheeler causing it to almost hit me but I had to slam on the gas very rapidly. There is usually a warning light on about parking break not working when these happen.

While on a cross country trip and while on the highway using the Tesla auto pilot and/or adaptive cruise control, we experienced numerous phantom braking incidents. Several while driving during the day with no other vehicles around and several while passing semi trucks in the other lane. At night the same thing occurred and on one occasion, with no other vehicles around, suddenly braked from 70 mph to near stop. Had we been on a wet or icy surface, there is the possibility of control issue.

Multiple times, the vehicle braked on its own while traveling eastbound on the Interstate 8 freeway between Yuma, AZ & Gila Bend, AZ. This was when no other vehicle or obstruction was on the freeway within a mile of the vehicle. The braking was very jarring, and if another vehicle was behind us it could have easily caused a high speed rear-end collision.

While driving with cruse controll, auto pilot, or adaptive cruise control my vehicle brakes suddenly without warning and without any reason or danger. This has happened many times. Today on the I8 traveling from Yuma az to Surpirse AZ the car braked around 15-20 times with out reason. I held the tesla car symbol on the screen to report the problem.

While driving on a two lane highway I experience daily ghost braking incidents. While doing 75, in both cruise and autopilot mode, the car will slam on the brakes when approaching a semi in the right lane. Today it even swerved to the right without the semi moving out of its lane. I also experience panic braking if a car crosses the lanes in front of me even if it is 500m away and the crossing car even left the road before braking occurs.

Vehicle suddenly brakes while in autopilot with no road obstructions. This has happened to me several times and I'm concerned that if someone is following me too close this may cause a collision.

Cruise control set to 82mph on interstate with no cars nearby. Car slams on brakes on multiple different cruise control sessions. Dangerous for other cars that could be driving behind me and could cause me to lose control of the vehicle.

I was driving on I-35 from Kansas City to Des Moines on 9-11-23, and three times the car experienced phantom braking (i.e. the car suddenly braked for no apparent reason) while the adaptive cruise control was activated. During these instances the car would suddenly brake and slow down and on one occasion I had to accelerate immediately to avoid possibly being rear ended. On all occasions there were no obstacles on the road or cars within 1/4 of a mile ahead of me.

On 09/08/2023 while the vehicle was engaged in Autopilot/Traffic Aware Cruise Control and at highway speeds, the vehicle suddenly braked with no visible / reasonable cue from the surroundings. Minutes later, it suddenly braked again suddenly and without any visible cause but with more force. After this, I stopped using this feature of the vehicle for the remainder of our trip. A similar event occurred around Apil 2023 and when I reported this to the Tesla Service Center they replaced both the right side and left side repeater cameras (faulty). The first incident of this nature occurred around a week after taking ownership in late October: Again at highway speeds, the vehicle suddenly and abruptly braked without cause. The Service Center was notified but they found no issue with the car. This type of behavior places myself and my family at risk of being rear ended with the abrupt nature...

The car does phantom braking on the highway when using cruise control. It is usually caused by a truck in the neighboring lane applying it's brakes, but not entering my lane.

1. When vehicle is on autopilot mode. Vehicle will all a sudden brake by itself with no reason as to why, no cars in front of me intermitly. Mostly happens when driving at highway speeds and when approaching a overpass. 2. Could be crash from the rear. 3. Have not notified Tesla. 4. No inspections have been performed 5. No warnings and no beeping either just brakes by itself intermitly.

We were driving on cruise control on 7/24/23 between the hours of 6AM - 8AM on a completely open highway with no cars near and no objects in the road. Our car braked on its own when we were driving 74-77MPH bringing the car to an almost complete stop. The same thing occurred on 7/22/23 between the hours of 9AM - 2PM. It was extremely scary and an obvious malfunction/ defect of the car. We both have back pain now from the sudden stop.

The car makes unintended braking when there is no vehicle in front. The car made a sudden brake from 75 mph to near 0 mph such that the driver felt that the vehicle almost flipped.

While driving westbound on US Rt 50 in Nevada with AutoSteer Beta engaged, car repeatedly decelerated rapidly with no audible or visual warning presented. This "phantom braking" could easily put vehicles traveling behind mine at risk of a collision. I have been able to reliable reproduce this in certain conditions - when a mirage is present on the roadway ahead and there are no cars immediately in front, the visual object detection system is apparently thrown off by the refraction of light and incorrectly detects cars, pedestrians, or motorcycles where none exist. As I see it, there are two major problems in play here - one is that the camera-based object detection system is easily confused by the presence of mirages on the road surface ahead and there are no other sensors in other portions of the EM spectrum (IR LIDAR or RADAR) to confirm the presence of visually detected...

During my first highway trip from Dallas to my home in Alpine, TX, I experienced numerous instances where the car would suddenly decelerate as if I had applied the brakes. At first I thought it was because there was a lot of road glare because I was driving late in the day into the west sun, but the next day it happened early in the morning when the sun was behind me and the road was straight, relatively clean with clear markings. The ultimate instance was when I was driving on a newly reopened dark asphalt road with new markings, straight, no glare, sun behind me. Clearly there is a problem.

While traveling on a busy interstate highway, my Tesla 3 presented four errors on the control screen: Automatic Emergency Braking disabled, Power reduced, Vehicle shutting down and Unable to drive. The left hand side of the screen flashed red and instructed me to pull over safely. The car was immediately slowing down, and as I was in heavy traffic, I was unable to pull over to the shoulder safely. I turned on my hazard lights and performed a soft reset of the car - which caused my hazard lights to turn off, all while cars were honking and whizzing around me. After the car reset, I was able to drive a short distance, with enough speed, to cross several lanes of traffic and come to a stop on the shoulder emergency lane of an exit ramp. The car is only 6 months old, with 4000 miles, but had to be...

Emergency braking applied when no other vehicles were in sight. Braking was hard enough to spill coffee. Seems to occur when adaptive cruise control is on. Happened about 10 times on recent road trip. Lucky no one was behind us! Felt very unsafe.
