2022 TESLA MODEL 3 Forward Collision Avoidance Problems

All safety and driver-assistance systems on my 2022 Tesla Model 3 failed due to an internal short in the vehicle’s computer, as confirmed in writing by Tesla’s technician. All cameras (rear, side, front) are non-functional, navigation does not work, and all ADAS features (Autopilot, lane-keeping, collision warning, blind-spot monitoring, emergency braking, etc.) are disabled. The vehicle has no visibility when reversing and no active safety protections while driving. Tesla documented the cause as an internal computer failure, not related to damage or misuse. This creates a dangerous condition on public roads since the car loses all safety systems. Tesla quoted ~$2,900 for a new computer even though the failure involves critical safety components. This may indicate a broader safety defect.

My family and I were in my Tesla Model 3 2022 and heading from Charlotte to Orlando on [XXX]. The car was in Full Self-Drive (FSD) mode while commuting through Daytona Beach. The rain was heavy in the area. While driving in Daytona Beach, FSD caused the car to change lanes and go to a lane that had standing rain puddles on [XXX]. After FSD caused the lane change, the car immediately hydroplaned out of control. The car's short clearance from it's bottom and the ground which traps water that exacerbates hydroplaning, along with its generative breaking feature made matters worse and uncontrollable. The car spun into the median three times and settled in the middle of danger interstate. The car is totalled. My family and I require medical attention and counseling due to the trauma.

While at a red light, my car was stopped with Tesla Full Self-Driving (FSD) on. When the car in front of me nudged forward, my car, still in FSD , accelerated and drove into the car in front. Looking at the event report of my car, the automatic emergency break did engage but too late. This means the sensors in front failed to recognize the vehicle ahead.

Tesla’s full self driving did not react to emergency vehicles approaching from behind.. vehicle was a police cruiser emergency lights, and sirens were active on freeway.

Then forward collision warning system inaccurately reported and reacted to a park car that was not in my lane. This caused my car to slam the brakes and subsequently almost cause an accident behind me. This also raised my car insurance premium so they can charge me more money

Tesla Model 3 while using the “FSD” or auto pilot mode will do what’s called “phantom breaking” with its emergency breaking system. This is very scary and has almost caused more accidents than preventing them in my experience. Tesla had not addressed or fixed this issue even with their constant software updates. How is this FSD considered legal I wonder.

Tesla M3 RWD 2022 - 79750k miles. Touchscreen keep restarting throughout the day , in the morning when I am backing out of the garage, while I am driving, while I parked. It is dangerous specially while I am backing out of garage, car will stop sometime, because whole system reboots. I have no visibility I have to wait till its finish restarting. Tesla's main computer handles everything in the car, A/C, Turn signals, speedometer, backup cameras, forward collision warning and many more necessary function of the car. Tesla service center diagnose stats "The cause was identified as kernel panics detected in the system. The internal memory of the car computer is corrupt and will not allow enough data transfer and causing the computer to reboot to clear space" They suggested to replace the computer and its a out of warranty fix, since I drove 79k miles. This is a crucial of the car and it should not fail in 3 years, driving 79k in California is not unusual, Tesla service also blamed that we didn't extended our warranty after 50k. We couldn't find any correspondence from Tesla on service app or email regrading warranty extension. $3000 to replace a computer is a very high price.

I pulled up to a red light in a protected left turn lane. My car is set to use regenerative braking and hold/not roll once stopped. I felt my car roll forward a bit, which shouldn't happen when these settings are on. I quickly checked my rearview mirror, assuming someone had hit me from behind to cause me to roll forward. No one was behind me. I hit my brake and the car suddenly accelerated at full throttle speed, I would guess, into the intersection, despite the light being red for me. I quickly glanced down at my foot to confirm that it was on the brake pedal and it definitely was. I continued to repeatedly push the brake pedal down to no avail. I was steering and tried to navigate my way through 4 lanes of moving traffic because they had a green light. I hit the front end of a car, which didn't slow my car at all. I went on to hit another car's front end, which didn't slow my car at all either. My car then charged out of control to hit the curb on the opposite side of the street facing traffic. Hitting the curb stopped my car finally. I noticed that the airbags on the right side of my car were deployed. Components that failed/malfunctioned: brakes, fuel/propulsion system, speed control, automatic emergency braking, collision warning/avoidance, traffic signal detection Tesla Insurance has deemed the car a total loss. I also reported the malfunction to their Vehicle Support but haven't gotten the report or the data report from the car that I requested yet. I was told that the report would be complete by 8/7/25. The car was placed on a hold for the investigation, so it should be available for inspection. I do have the dashcam videos and photos of my car, if needed. This incident was terrifying because I had zero control of my vehicle due to the sudden unintended acceleration (SUA). I see on the internet that SUA is a problem with Tesla that has been reported repeatedly. It is a miracle that no one was hurt or killed. Tesla needs to address this immediately!

While driving on AutoPilot the I-10W on Wednesday July 16, 2025, the car suddenly and very harshly braked for no reason at all. The vehicle in front of me was visible on the vehicle's display, meaning it was keeping it distance and was actively adapting to its speed and distance, and at no time did I press the brake or move the steering wheel for the vehicle to use its emergency braking. It was so harsh, I felt the blood throughout my head and body lunge forward, and AutoPilot immediately turned off. If I wasn't aware of this sudden braking, I would have assumed AutoPilot would still be active, but knowing of Tesla's "phantom braking", I immediately took control once I noticed AutoPilot turned off on its own. I have a video of the dash cam available (over 10MB) if needed.

While traveling at approximately 70 miles per hour on an interstate, the vehicle's automatic emergency braking system engaged multiple times in rapid succession—approximately five separate braking events. Each time, the system falsely detected an obstacle, which it appeared to interpret as a person in front of the vehicle. In reality, there was nothing on the road; the system was reacting to a roof-mounted strap that was fluttering slightly in view of the forward sensors. These false positives caused the vehicle to brake suddenly and forcefully, creating a highly dangerous situation for vehicles behind me. Multiple drivers were forced to swerve to avoid a collision. Thankfully, no crash occurred, but the repeated unexpected braking posed a serious risk to my safety and the safety of others on the highway. Additionally, I had previously disabled the automatic emergency braking feature in the vehicle's settings. However, I later discovered that this system reactivates by default every time the vehicle is restarted. There is currently no option to permanently disable this feature, meaning drivers must manually turn it off for each individual trip, which is not clearly communicated by the system. This issue has not yet been inspected by the manufacturer or a dealer. No warning lights or error messages appeared before or during the braking events.

I was traveling northbound on [XXX} in Sugar Grove, IL with the traffic aware cruise control on. As I passed under [XXX] the car braked heavily for no reason. No cars in the area...thankfully. I could have easily been rear-ended. It has done this on more than one occasion at this location. I filed a "bug-report" via the right hand button on the steering wheel. I was also traveling [XXX] near Lasalle-Peru with the cruise control on at about 80 mph when the vehicle suddenly braked heavily. No cars around at all. The moment was extremely frightening.

When the vehicle is set to regenerative braking mode, lifting off the accelerator pedal causes the car to decelerate significantly. However, in many cases, the brake lights do not illuminate during this process. This could potentially create a safety risk, as drivers behind may not realize the car is slowing down and may not respond in time. tesla

Forward collision warning was falsely triggered causing the car to inappropriately apply the brakes twice in one drive. This causes the car to brake harshly and causes cars behind me to either swerve or slam their brakes. This causes a chain reaction of extremely dangerous behavior. The forward collision warning system is far too sensitive when there’s literally no obstacles to cause a collision or avoid.

The cars forward collision warning system is far too sensitive and braked extremely hard when there was nothing to collide with. This caused the car behind me to slam their brakes and they got rear ended. This needs to be forced on Tesla to be addressed

Two false collision warnings were triggered when in fact, there was nothing to collide with. This caused the car to brake extremely forcefully nearly causing another can to rear end me in midday traffic. If they would have hit me, it easily would have caused a 10+ car accident.

The forward collision warning system is too sensitive. When cars are in a completely different lane, the car will sometimes think they are in your lane when they’re aren’t. This forces the FWC warning to alert and the brakes to slam. When this happens cars behind you sometimes swerve or nearly rear end me. This happened twice today march 14th.

As I was approaching a green light with stopped vehicles the car caught glare from the car ahead of me thinking it was stopping when it was turning. This caused aggressive breaking mid turn and caused a spike in my insurance as well as decrease in my safety score. I reported this as a bug to the car but they never get checked for fixed.

Computer system improperly triggered two false forward collision warning while changing lanes, today, on 02/02/2025. These forward collision warnings and applied excessive braking for no reason causing an increased chance of being rear ended or losing control. In heavy traffic, the car is constantly creating dangerous situations like this and the sensitivity of the forward collision warnings needs to be dialed back when the blinker is on or while in between lanes.

The car was advertised at 312miles on the battery. It is 265. The charging takes 45 to hr and I was lied to about the mileage overage and the ability to purchase the car. This car isn't as advertised. I reached out to tesla and they do t offer any solution. I was scammed. I want to return the car. The tires do t last as the cars are too heavy. If the tires don't last 1 yr that's a defect.

There has been numerous false Forward Collision Warning reports from my car over the past two years. Over 100 to be exact. These false collision warnings cause the car to brake abruptly increasing the change of being rear ended, causing accidents behind me or even causing my car to swerve. This has been witnessed by at least 3 different passengers of mine. Tesla refuses to acknowledge that their software can be flawed in any way despite my attempts to contact Tesla Service, Tesla Insurance, Tesla Support and Tesla Internal investigative services. I have requested a complete list of all Bug Reports and no one is able to reproduce them for me or give me a list. No my vehicle has not been inspected because Tesla claims that this is working as intended. Which, if that is the case, they're doing/using it to arbitrarily raise people's premiums and make them pay more with Tesla Insurance. No warnings. Just abrupt stops due to the camera improperly reading a situation, seeing something that isn't there, or simply activating out of thin air.

I'm not quite sure what component was affected, some module of some sort got water in or near it that wasn't supposed to. It is available for inspection. Yes my safety and others was out at risk. Yes the problem was fixed by service center supposedly. Yes the car has been inspected by the manufacturer. There were no warnings. What happened was on 12/29 I was driving the car and out of absolutely nowhere a bunch of warnings came up including loss of ABS, any and all safety features. And more importantly lost usage of brakes almost entirely when car came to a stop it was grinding and shakey. This problem all arises due to teslas negligence when it came to installing a new windshield on the vehicle. As stated in messages below, they made a mistake while installing my windshield that caused this major issue to arise. They have offered nothing as a solution but saying that their error is supposedly fixed.

Tesla needs to be required to implement trailer mode to all model 3/Y vehicles (not just those equipped with a tow hitch from the factory) because the basic autopilot and existing safety software does not correctly identify when the vehicle is towing a trailer. Legal Aftermarket tow hitch installations exist for small trailers, such as U-Haul trailer. However Tesla does not recognize these aftermarket installs. And Tesla needs to be required to add the required trailer software mode for vehicles with aftermarket hitches to provide the required safety software when towing. It is needed because of the cars emergency braking, collision avoidance, navigation, and autopilot modes need to know that a trailer is connected so that the vehicle software does not make an unsafe maneuver depending on the driving situation/condition.

Hi. My issue is partly related to case PE-22-002 and may also contribute to it as well. I will forward my dash-cam videos (the false detection of cars in-front of me for 63.5% of that drive is included here) to your email as support for the investigations. I have been noticing warnings that a car is in the lane I am changing into when there is no car present. This has happened several times, despite the camera showing no cars and checking for myself showed no cars. The first time it happened, it scared me so bad I jerked back into my lane and could have lost control of being safely in the lane. I filed a service request and was told it would cost me an est. $195.00 to have them look at it, but they said they think it is software related and tried to say they don't deal with software issues. It has experienced many occasions of decelerating for no cause when using the Full Self Driving, Autopilot and Cruise Control. It would cause me to have to disengage them as I felt it was effecting my distance efficiency. I found a new issue last night that caused concern. We have been getting high reports of following too closely, so I drove from Plainview, Tx to Amarillo, Tx in complete control myself while driving 100% perfectly and it reported that it claimed 63.5% of that drive was "Following To Closely" when in-fact any time a vehicle was in-front of me by (I think) 30 car lengths, I changed into the other lane where the was no vehicles in the lane at all. It is my personal opinion that it is a combination of the cameras not being infrared and not seeing well enough in low light situations, and the software unable to tell the difference between darkness/shadows and objects that should be avoided. These false alerts occur more for me in low light conditions, but the unneeded deceleration has occurred in all conditions.

In autopilot mode vehicle failed to recognize School bus with flashung red lights and children crossing in front of vehicle. Had to hit brakes

Tesla FSD almost caused a serious accident. My car was at a stop sign at a t in the road with cross traffic going 40-50mph. The car did not see a white car driving toward from the left as it pulled out. Instead of stopping before getting in front of the car, it pulled slowly into the lane and then errored out, stopping right in front of a car that was about to T-bone me. I had to take back control of the car and quickly accelerate before they crashed into me. Luckily the combination of me taking over and accelerating and the other car also slowing down drastically saved us from having a serious accident. Unfortunately I had a fresh cup of hot coffee in my left hand and the acceleration caused it to spill allover the left side of my face, neck and chest causing burns. None of this would have happened if I wasn't testing the free trial of "Full Self-Driving." This was only a block from my home and it couldn't even work properly for more than 2 minutes. Software is so far from being ready to be safely used it is going to kill people. I have dashcam videos of the whole thing and can provide to you.

I was driving I the Highway and the car start to move in another car direction, I went to Tesla they said is computer fault, but I’m not involved in any accident to get a computer issued and now I receive the letter reporting a problem And they don’t wanna fix this

Full Self Driving prominently suggests the user enable “automatic set speed offset”. When enabled it tries to guess the speed it should be going, and goes that speed. On city streets and rural highways the driver is unable to lower the speed with the normal cruise control speed dial. it is disabled. It recognizes when the speed limit lowers on the road, but does not adjust to that new limit. The only option is to hit the brakes or otherwise disable the system. On the interstate this resulted in it resetting to the maximum 85 MPH as it was setting itself to 86 at every deactivation. Turning cruise control back on, despite having previously set it to the speed limit, causes it to to immediately accelerate regardless of the posted limits or the previous setting.

The noted vehicle is one of 7 Teslas (6 Model 3s and 1 Model Y) that I have rented from Hertz for a round trip from Orlando Fl to Naples Fl. Over the last 7 months. Each of the Model 3 vehicles was different, I never got the same Model 3. Each of the vehicles exhibited the same or similar glitch when traveling on [XXX] at [XXX] when either the navigation and/or the adaptive speed control was engaged and traveling at or near the posted speed limit when nearing this specific exit. If only the navigation system is on it will direct the driver to take the exit and then return to the interstate using the on ramp. If the adaptive speed control is engaged, either with or without the navigation feature on, when the vehicle is on [XXX] near or under the overpass it will abruptly try to slow the vehicle to 35 MPH, the speed limit for traffic on the overpass. None of the rental vehicles has the full autopilot activated to my knowledge. This event will occur when traveling in either direction and has only occurred at [XXX] on my 200+ mile trip. Having this occur once or twice would be strange, but 7 times at the same location over 7 months in 7 different vehicles is more likely a glitch of some kind, and one that could result in a crash if a driver is unprepared for the unexpected rapid reduction in speed. [XXX] is heavily travelled with both local and out of town drivers in both personal and rental vehicles. I have no idea if this is occurring at other locations but it seems to be consistent here. Since the adaptive speed control must be using information from the navigation system to display and utilize the speed limit to regulate maximum speed, it is likely the problem is in the navigation system.

While driving with the cruise control set, at times the care must sense that there is an issue ahead and slams the brakes on. This has happened on numerous occasions. This had led to cars following to do the same (hard braking). Although this has not caused an accident for me, I don't trust the system. I'm waiting for a rear end collision when this happens.

This car will suddenly slow down for no apparent reason when driving with the speed control set. I have experienced this multiple times at 2 specific intersections. It has also happened at other times but on roads I have traveled on less often. Traffic aware cruise control is always enabled on this car. There isn't an option to turn it off. I scheduled a service visit with Tesla explaining what was happening at these 2 specific intersections (I included the intersection specific information). They responded and said they performed a remote diagnosis on the Autopilot System in the vehicle and its affiliated hardware and all checks came back in good standing with no faults. They went on to state "just as a reminder as Autopilot/Traffic aware cruise control is under Beta, per owners manual, many factors can impact the performance of Autopilot/Traffic aware cruise control components. Autopilot/Traffic aware cruise control may occasionally cause vehicle to brake when not required or when you are not expecting it." They referred me to the owners manual where these warnings/limitations were reiterated. I replied and asked what Tesla was doing to improve this situation. I did not get a response. I am very concerned about this sudden braking/deceleration as it may result in a rear end collision if someone is following closely when it occurs. I believe Tesla should be more transparent about what they are doing to resolve the issue. They should also provide an option to turn off the Traffic Aware cruise control until the issue is resolved.

Tesla summons was used to summons the car. Vehicle drove forward as directed and failed to clear car on left when pulling out of the parking space to go left. Vision systems and ultrasonic sensors failed to detect and perform safety measures resulting in vehicle collision.

The Tesla model 3 from the factory does not have the option to get the trailer mode safety software. Aftermarket suppliers make and sell class 2/3 hitches for the model 3. And while the model 3 is not rated for towing. People still have the tow hitches installed and they tow trailers. The model Y with the tow package has what is called “trailer mode” which enables safety features for towing that allows the vehicle to do several things for safety while towing: - it adjusts the wheel braking and speed stability. - It routs to “pull through” charging stations for safe charging without having to unnecessarily and repeatedly unhook trailers. - auto steer, automatic steering, emergency braking, and following distance is all adjusted to account for the trailer and its weight. - light check, checking for functional trailer lighting. The Model Y that does not get the factory tow hitch does not get this tow package software. If you get the tow hitch added afterwards on the model Y or aftermarket, Tesla does not provide this safety enhanced software. The model 3 does not get this safety software regardless. And yet people are able to install after market tow hitches I believe Tesla should be required to offer the towing software to the Model Y base and Model 3 regardless if the vehicle it tow rated or not because the safety of the vehicle when towing is a necessity. I don’t think it should matter if they charge money or offer it free so long as you can have this trailer mode software option added for safety. Because people are going to tow with their cars. A lot of people don’t follow manufacturer recommendations. And U-Haul trailer rental among many other providers offers tow hitch installations and rents trailers to people with Tesla’s. So the easiest thing is to require Tesla to provide this safety enhancement to every vehicle and not just the model Y “if it gets the tow package from the factory.”

My Tesla sets off false front collision warnings multiple times a month, resulting in distraction, but more importantly, it increases my auto insurance rate through Tesla Insurance. I am not sure if Tesla is working on this "bug" or if it is intentional to keep driver safety scores below a certain threshold. I have video proof from the car itself indicating that there was no imminent collision threat.

At 7:50 this morning I had my first drive with Tesla FSD 12.3.4. It had been going very close to curbs on the passenger side on 12.3.3, but this is the first time it hit the curb and damages the tire rim. The current version of the software puts the car much too close to the curb, something not present in prior versions.

Car will randomly jam on the breaks while going down the interstate.

Tesla updated my vehicle last night, this morning with out any clear warning my cruise control activation actually activated the "full self driving" I did NOT realize this until my car turned the blinker on and tried to change lanes!!! I had no idea what it was doing! I took back control and tried to activate cruise control again but had self driving activate instead. So I just drove to work manually. When I got to work I looked up how to activate cruise control and realized that there is a setting to change how it is activated that I could change to get it back to "normal" for me. Then I was checking my email and Tesla had "Gifted" me a trial month of full self driving, they changed how my car functions without telling me and it literally started driving itself much to my surprise all as a PROMOTIONAL CAMPAIGN. Frankly I am pissed, this is unacceptable! They radically changed how my car behaves, what my controls actually do, without telling me, to make more money.

Issues became more prevalent as soon as Tesla Insurance 2.0 came out. My car has become too sensitive often giving me several false forward collision warnings per day. This includes parked cars on my street as I’m coming in around a long corner, cars in turn lanes, and cars that I’m not even close to all being registered as collision warnings. This causes my safety score to drop for no real reason causing my monthly payments to be more. I think this is entirely done on purpose and has nothing to do with actual safety. I have scheduled service appointments and talked with Tesla insurance and they give me nothing but excuses and the run around.

Vehicle has been scheduled for service 4 times to address phantom braking while set to cruise control on highways. Tesla service center continuously resolves the problem remotely stating that there are no faults in the system and it is operating as intended. I’m an airline pilot and my vehicle poses a safety hazard to me and those around me when operating in any autonomous mode.

On [XXX], I was driving from Victorville, CA to Las Vegas, NV on [XXX] northbound. Between [XXX] two incidents occurred. Both incidents involve phantom braking. My vehicle was in autopilot mode, which is essentially traffic aware cruise control. I was traveling at 70MPH and passed a semi-truck. I changed lanes back into the right lane after passing the truck. About 30 seconds later, the car slammed on the brakes. The semi-truck behind me took immediate evasive maneuver and swerved into the left lane to avoid hitting me. There was no obstruction in front of me. The nearest vehicles ahead of me were so far away that I could barely see their tail lights. This was a very unsafe condition. The second incident happened about 40 minutes later. No other vehicles were near me although the sudden braking gave me a scare. There were no warnings, messages, or any indication that the sudden braking was being applied. I was able to immediately depress the accelerator to increase speed and override the autopilot. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Traveling on I35 South, approx 70 -75 MPH. Using adaptive cruise control/enhanced auto pilot. No vehicles present within a mile of my vehicle. Braking spontaneously engaged, reducing speed to 40MPH within seconds. If a vehicle were behind me they would have absolutely collided. I've not filed a report with Tesla. Vehicle did not display any warning, or any other sort of indication that a malfunction had occurred. The problem has not been reproduced by me, however an internet search returns multiple complaints of these exact symptoms.

Traveling on I35 South, approx 70 -75 MPH. Using adaptive cruise control/enhanced auto pilot. No vehicles present within a mile of my vehicle. Braking spontaneously engaged, reducing speed to 40MPH within seconds. If a vehicle were behind me they would have absolutely collided. I've not filed a report with Tesla. Vehicle did not display any warning, or any other sort of indication that a malfunction had occurred. The problem has not been reproduced by me, however an internet search returns multiple complaints of these exact symptoms.

The contact owned a 2022 Telsa Model 3. The contact stated that while driving at 18 MPH, the vehicle veered to the right hitting an electrical pole. The contact stated neither the autopilot nor cruise control was set to on, and the vehicle failed to stop. The contact stated it happened so fast he was unable to depress the brake pedal in time. No warning lights were illuminated and the air bags in the vehicle failed to deploy. The contact sustained a knee injury and later received medical attention at an urgent care. However, the contact stated he was traumatized from the crash. The vehicle was towed and deemed destroyed. A police report was filed. The contact notified the manufacturer of the failure. The failure mileage was approximately 21,372.

Something occurred with the steering, automatic braking, or lane keeping assistance on [XXX] at approximately 6:35am while I was driving my 2022 Tesla Model 3 Long Range North in the carpool lane just south of [XXX] in Sandy Utah. The roads were a little slick so was proceeding cautiously at around 65 MPH when the car turned to the left slightly, then immediately to the right, which caused it to do a 180 degree turn in the same lane, I wasn't sure what was going on as the car felt like it was driving itself. Before I knew what was happening, the car then veered to the East across three lanes of traffic while driving backwards, it then stopped just as it was struck in front of the wheel on the front drivers side by a two trailer semi-truck which spun the car around. Luckily I was conscious so could slowly limp across the last couple lanes to the right side of the road where I called 911. I've driven all kinds of cars in all kinds of conditions and in many countries in the nearly 32 years I've been a licensed driver and have never lost control of a vehicle, I'm sure the steering or lane assist was trying to intervene so must've somehow inadvertently caused the crash! It's only through the grace of [XXX] that I'm still alive to tell about it! Also, none of the airbags went off even though the impact from the semi was very jarring!

Car slammed on the brakes on its own while the auto steer function was being used going 80mph. If someone was behind me they would’ve rear ended me.

On 9 different occasions, my vehicle was operating in cruise control and slammed on the brakes for no reason. Fortunately, no vehicle was behind me. If there were I would have been rear-ended all 9 times. This has happed 8 times on the freeway and one time on surface streets.

the car started to abruptly accelerate when slowing down the car at a stop light and would not brake. the anti collision functions did not work. the car went into a truck.

Driving on the freeway 70mph on cruise control. Not auto pilot. No one around us and no warning. Suddenly car applied brakes on its own and dramatically slowed. Good thing there was no one behind us or else there would have been an accident and we would have been badly injured. Monday Jan 1 2024 1:35pm

Autopilot warnings are too excessive. Looking at the screen of the car causes autopilot warnings to trigger and disengage car, automatically slowing car down in the middle of traffic. Changes need to be reverted back to baseline from 11/2023.

The fix for recall 23V-838; TC2023-657 has made using the feature more unsafe to use than in previous iterations.

Tesla vehicles autopilot. I know you already have a situation with Tesla over the basic Autopilot. My safety report is about red lights and stop signs. Tesla reserves this feature for their FSD package. While basic and enhanced AP cannot identify red lights or stop signs. For the basic AP, I suggest that Tesla be required to include red light and stop sign identification in their basic autopilot system. While geo-locking AP is a current temporary solution, it is not the correct solution IMO. The correct solution I believe is to force Tesla to include red light and stop sign identifying in the basic and enhanced AP software. In addition to including red light and stop sign identification in their forward emergency braking safety system. Imagine how many intersection related collisions can be prevented if you make the vehicle capable of stopping. Especially when the driver could be having a medical emergency and cannot stop their car. Two ways. Option 1: Vehicle stops at red light for the driver, everyone is safe. Option 2: vehicle runs the red light, not using autopilot, vehicle T bones someone in the intersection. I highly suggest a pro-active approach that promotes a safe environment on the road rather than a punishing approach that promotes human drivers to continue as they are. After 40,000 miles of Autopilot, I can confirm that it’s a better driver overall than any human. Humans will eventually make mistakes, software will do the same thing repeatedly. The only reason software makes a mistake is because it wasn’t designed to be used in an application, so basically it’s still human error. I suggest to require the software to take over in more ways to prevent human error from happening more often. The less humans need to do, the less chance you have of collisions. Summary: Basic AP should have red light and stop sign ID to stop. And forward collision stopping should also have red lights and stop sign identification.

This happens at 2 particular exits on a 65mph highway. One time the car slows down by 10mph and the other spot it will swerve over almost to the lane next to me and slow down. Just dangerous when someone is tailgating me (thats reality of driving these days) as they will not have time to react and more than likely hit me. It happened once and someone behind me started honking and flashing their lights at me. I have done a bug report for the times it "phantom braked"

Please help Phantom braking is getting worse

It was a raining day. When I turned 90 degree to my right into the parking lot from local road, I hit the brake and the car slowed down for turning. FSD or autopilot were off for sure. Then I felt the car was moving down suddenly and made a big noise due to the a slightly slope down when I turned. I saw a parking slot right in front of me. I hit the accelerator a fraction of second to prevent the car to stop. In a fraction of second, the car accelerated like crazy. I immediately hit the brake very hard (95% of my force on brake). I have 30 years of driving experience. I knew that I hit the brake tightly, but the car still kept accelerate like crazy. I could forever remember the feel and moment of my foot was in the brake. Even after the accident, I went to test the Tesla car. I could feel the difference of brake and accelerator since the accelerator is much easier to push down and I needed to push much deeper in the right of my right foot for accelerator. And the brake is hard, and close to my foot. I thought the car would stop like what I had been driving this car for one year and about 20,000 miles. However, the car was stopping at all, but keeping accelerating for 2 seconds. No warning lights and AEB were on at working. The car hit the short of concrete wall and steel fence and then dropped and hit the tree in right front of me. Finally the car dropped into the short cliff. The airbags were off and warning lights were on. My son and me could use the manual door opener to go out.

While driving both during the day and at nighttime on the freeway with cruise control, the car abruptly brakes itself. No car was in front of me in any of these incidents. I have owned the car for a year and it has happened at least once a month. (I drive a lot for work.) The vehicle is available for inspection upon request. My safety and others' safety was put at risk because when traveling at high rates of speed on busy freeways with multiple lanes, it is easy for something like that to cause a multi-car accident. I live in a major metropolitan area and the freeways are up to 5 lanes across going one way. The problem has not been reproduced or confirmed by anyone. The vehicle or component has not been inspected. there were no warning lamps, messages, or other symptoms of the problem prior to the failure. It first appeared within the first month of ownership.

I was traveling on Interstate 40 in Arizona in a 75 mph zone with my cruise control set at 77 mph. Suddenly and without warning the car’s emergency braking system activate despite nothing being in the roadway in front of me and no cars ahead at all. I had to take evasive measures to avoid being hit from behind by a semi truck. Approximately 10 seconds later I began receiving error messages for several systems including emergency braking, traction control, steering alignment, lane departure, stability control, cruise control, vehicle hold, and regenerative braking. In addition, other systems were not working, such as an alert tone for when traffic lights turn green would activate indicating the driver should go even if there was a car in front that has not moved. The car is currently at Tesla being evaluated, however I really don’t think these cars should be trusted.

There has been several false forward coalition alarms each month so far with no reason when I’m even driving in an easy and not a crowd street or highway. The alarm is so loud that everybody in the car panics including me and it dangerously interrupts my driving. This has caused me suddenly hit the brake several times which also may cause panic the drivers around me or at my back and put the or us in danger.

There was a forward collision warning I got with a parked car when going less than 20 mph when the road was curving. The car is defective and I shouldn’t have gotten a forward collision warning which causes distraction from the loud and sudden noise it emits. It also negatively impacts my Tesla insurance safety score which is a scam.

I have been forced to stop using cruise control on my Tesla Model 3. Over the past few years, the car will repeatedly slam on the brakes for no good reason when I am driving on the highway. I understand this behavior is known as "phantom braking." The car will suddenly and unexpectedly drop speed by 10-20 mph on the highway. I am so worried that someone will rear-end my vehicle that I cannot use cruise control anymore. For some unexplained reason, the Tesla Model 3 does not currently have a "dumb" cruise control that I could use instead.

When driving using adaptive cruise control, it breaks for no reason slamming the car into a stop. Also, with adaptive cruise control regardless of the set speed limit it speeds up to whatever it once, which is a huge safety factor.

I took a recent road trip of 1,200 miles across the southwest. Numerous times while using adaptive cruise control the vehicle suddenly and violently braked for no apparent reason. This was particularly concerning when passing trucks. One particular event was on interstate 5 when passing a big rig truck, I was along side the truck with a following car tailgating me, my car suddenly braked hard, creating a risk of rear end collision at 70 miles per hour. I was able to accelerate to avoid a collision. I did not keep track of the number of events of sudden unanticipated braking, but I would estimate more than 50 instances. They vary from momentary slow down to violent sudden breaking.

The contact owns a 2022 Tesla Model 3. The contact stated while driving at an undisclosed speed with the cruise control activated, the vehicle experienced phantom braking. The contact stated that no other vehicle or objects were nearby. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 19,700.

My car was purchased Aug 2022. In Nov. 2022 we took a short trip. I believe 5 or 6 times the car braked for no reason. I believe it is called phantom braking. One or two times it was a hard brake that I believe could cause an accident if someone was behind me, or the wrong person driving. It was sudden and hard in those two situations. I took the car in and after they drove it two miles they told me there were no issues. Then in June 2023 we went on a long trip. I do not use autopilot, this is only cruise control. On this trip probably between 35 to 45 times we experienced the same issues. At least 5 times they were hard brakes and could cause an accident. I again opened a service visit to Tesla. Again, they drove the car 5 miles and claimed there is nothing wrong. I did not accept this answer and asked for the GM. Finally after demanding this for 20 or so minutes a man came and said he was the manager. He also argued in the beginning but when I told him I have found accidents caused by this he finally admitted that it was something called "phantom braking" and that that it should be fixed very soon with an update. So then again, in August my wife and I went on another trip. It still is happening and probably 6 or 7 times this occurred. It seems to mostly be on smaller 2 lane highways and occurs usually when there are no cars, trucks, or anything nearby. But all it would take is a tailgater to cause a wreck. In August when we returned I made another warranty appointment her in Las Vegas and immediately they cancelled the visit on my app. They are lying about what is occurring and telling me that it is usually when I am following too close or some garbage like that, which is absolutely not true. I just made another appt today but I am sure they will cancel it. What do I do. I really want to go through Nevada Lemon law at this point. My name is [XXX] and my phone is [XXX] .

I was in the carpool lane when traffic came to a complete stop. I pressed on the brakes but they were heavy as if I was not able to press it down all the way. There was no information prior to the accident from the Tesla trying to warn me about an incoming collision. It wasn’t until after the accident the Tesla acknowledged that there was damage done to the car. Prior to the accident there was a service required for the front passenger safety restraints. This accident could have been much worse as I tried to swerve out of the way to avoid traffic but wasn’t able to make it back in time.

We took our first long-disance trip (Albuquerque NM to Arlington TX, round trip) in our 2022 Tesla Model 3 and experienced multiple (4-5) phantom braking episodes to and from Arlington when engaging adaptive cruise control or autopilot. The car had been driven 5,760 miles before the trip. There were no warnings before the braking. The car was travelling at 70-77 mph on interstate highways and suddenly the brakes would engage slowing the car to 40 or 50 mph before we pressed pressed the accelerator. It was a clear day with temperatures in the 90-100 range. One time the phantom brake episode occurred while passing. Fortunately, there no cars travelling close behind us or there could have been a serious multi-car accident. We contacted Tesla service and they told us the car had no discernable problems (attached message).

On multiple occasions, I have had phantom braking issues with the car. Most notably, I have experienced this on Highway 80 between Fernley, NV, and Winnemucca. Originally, I was using the car's autopilot feature and I had multiple phantom braking events. I had the speed set for the speed limit of 80 MPH and the car randomly slammed on the brakes. By the time I was able to hit the gas pedal, I slowed down to about 60 MPH. Fearing I was going to cause a traffic incident, I stopped using autopilot and used the adaptive cruise control. I suffered over 50 phantom braking incidents with the adaptive cruise control. I kept using the feature so I could log a case with Tesla. Once I got home, I logged a case with Tesla and they said the cameras were dirty and that was the issue. On a second trip, taking the same route, I cleaned the cameras and had the exact same results. I have noticed taking the same route, I only have issues when it is sunny out. When it is dark, with less glare, the car operates okay. Autopilot and Tesla's adaptive cruise control are incredibly dangerous. I requested to have a standard cruise control, which Tesla said was impossible to get. I had a previous Tesla with standard cruise control and don't understand why we can't have that feature. Please investigate this and make Tesla offer a standard cruise control option so we do not have to risk our lives with their dangerous autopilot.

While driving at 55 MPM on Interstate 66 West near Reston, I was using Tesla Autopilot and experienced a very sudden heavy braking, braking to about 35 MPH in a second or less. The braking was so sever it lifted me off the back o f the driver's seat. The closest vehicle in my lane (rightmost lane) was easily more than a quarter mile ahead. There were no vehicles on the 2 lanes to my left. I was not near an exit nor was there an overpass ahead. This occurs frequently while trying to use Tesla Autopilot in a variety of conditions. In each case there is no obvious reason for the sudden braking while using autopilot. This is quite scary and clearly dangerous. My frequent passengers all ask me not to use Tesla autopilot while they are in the car. As a comment, I would be quite happy if Tesla provided an option to only use autopilot for keeping the speed without anything else.

On 8/3/23 on two occasions the vehicle suddenly applied brakes while in cruise/autopilot mode when there was no vehicle in close proximity in front of my vehicle. There was however a large commercial truck behind me on one occasion, which may have been effected by the application of brakes for no apparent reason. On 8/5/23, with the vehicle in the same mode, the system applied brakes.....there were no vehicles within a 1/4 mile front or rear. Tesla was contacted and reviewed the logs, stating that the vehicle braked for another vehicle..... As a 35 year police officers, my professional opinion is that this vehicle is dangerous when operated in this mode. I explained this to Tesla and their response was that sometimes you get false activations because the car perceived something that wasn't there and that's Ok. It's not Ok to unexpectedly step on the brakes at 70 or 80 miles per hour on a major highway! Had it been my daughter or my wife driving, I'm not sure they would have reacted as fast nor in the correct manner as it is confusing when it first happens.

On Friday, August 11th. My wife and I were traveling on I-70 Eastbound from Colorado to Kansas. On several occasions during the trip, we experienced phantom braking while using the adaptive cruise control. The car would immediately brake at highway speeds, slowing rapidly when nothing was on the road. Luckily every time this happened there were no cars immediately behind us as it could have easily caused a crash. This happened both while I was driving [XXX] ) and while my wife was driving [XXX] ). At one point in the trip, we turned off the emergency braking feature and the phantom braking still occurred while using the adaptive cruise control. In all this happened around 10 times or so during the trip. I reported the event to Tesla on Monday, August 14 as neither of us felt safe using the adaptive cruise control after that event.

I believe the autopilot and cruise control systems are affected. On 6-8 occasions, the cameras have picked up a non- existent hazard along the road causing the cruise control to disengage, rapidly slowing the car approximately 20 MPH in about 3 seconds. This has occurred on highways and freeways at speeds of 65-75 MPH. If there had been another vehicle traveling close behind, an accident would likely have occurred. I’ve taken the car to the dealer and they are aware of this problem. After the dealer adjusted the cameras the problem persisted. When this problem has occurred, there was no prior warning.

Car brakes hard on cruise control when no other cars are around.

I was using Tesla autopilot today while driving from corpus christy to Fulshear. Multiple times it slammed the brake on the freeway even if there was no one in front of me at all. This caused lot of panic to all of us specially passenger seat folks. It was extremely scary and could have resulted in long pile up on the highway.

Was traveling on Interstate 94 near Steele, ND in broad daylight on July 30. The sky was mostly clear and it was not raining. There was no road construction on this stretch of road, . I was westbound in the right lane with no traffic approaching me or behind me: it was a rural roadway with no curves and mostly flat. At 7:39 PM Central time near mile point 198 the car braked without warning very aggressively. I continued traveling with the auto cruise and at 7:40 PM Central time near mile point 194 it again very aggressively braked with nothing but open straight highway with no vehicles, signs, construction or anything else that could have caused this to happen. I continued my journey and it happened several more time until I no longer felt safe using the adaptive cruise. This has happened before and Tesla Service asked me to track the event and report the time when it happened. I reported the above incident to Tesla and they scheduled a repair for August 8. Today they canceled this visit for repair and told me that this was something that occasionally happens with the cruise and that they were canceling my appointment. They told me that if I wanted to drive to the nearest service center that they too would not be able to fix it. I was lucky that this happened in North Dakota on a rural highway. The wheels locked on me and the tires even slightly screeched. I ascertain that had this happened where there would have been someone behind me there would have been an accident. Tesla clearly is not interested in fixing this and told me that if I did not feel safe that I should not use the cruise. I hope you can resolve this before there is a death or serious injury. I have talked to other Tesla Model 3 owners who have experienced this. Thank you for your consideration

On 19 July 2023 at approximately 4am in the morning, while with my wife traveling north on I-95, I was driving approximately 77 mph and my 2022 Tesla Model 3 SLAMMED ON THE BRAKES. I had several cars directly behind me that had to slam on brakes and perform other evasive driving maneuvers as well. Luckily my reaction time was quick enough for me to SLAM ON THE ACCELERTOR to avoid a very serious wreck and pile up. This is the 3rd time this has happened but thankfully the first 2 times I did not have traffic directly behind me. Although I paid an extra $6000 for the Enhanced Auto Pilot, I do not use it, as I am now scared to death of this car at highway speeds. On the night/morning of 19 July, I was on just regular cruise control. The very next day (20 July) I applied for an appointment with the local Tesla Service Center here in the Richmond VA area. After a couple days, and I had not taken the car in yet, Tesla sent me a message and informed "that I am NOT to bring the car in." I have not heard from them since then... and today is 5 August 2023. Respectfully request that you weigh in to either get me a Refund for this car, or in some way restore my confidence in it. I am scared to ever put this car on the highway again. THANK YOU.

Driving at speed limit (70MPH) on Interstate 5. Was using cruise control. On 5 occasions, driving N, then S 4 days later, car braked suddenly with no obstacle or vehicle within 50 yards.

While driving on freeway with adaptive cruise control engaged, the vehicle suddenly slammed on the brakes with the wheels initially locking up (there was an audible screech from the tires). There was no traffic obstacle that would have suggested that there was a reason to do this. It was daytime and the weather was clear. I was able to immediately take control of the car and re-accelerate to prevent vehicles behind me from rear-ending me.

The contact owns a 2022 Tesla Model 3. The contact stated while driving at an undisclosed speed, the vehicle experienced phantom braking. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 400.

Mileage: 400

I was driving my 2022 Tesla Model 3 Long Range. This car does NOT have Autopilot (because we do not trust that technology). We were traveling eastbound on I-8 just east of Exit 61 from San Diego to Arizona on Sunday July 16 at about 2:30pm. The weather conditions were not an issue; it was sunny and warm. I was in the left lane doing 77mph with the Cruise Control on. I had passed a vehicle in the right lane and it was now maybe 500 feet behind us, still in the right lane. Suddenly, the Tesla Model 3 braked hard for no reason. The car braked so hard that the tires were starting to squeal. We were well inside the lane (had not drifted to either side). There were no obstacles in front of us. There was no discoloration on the highway from any repair or car fire. The road was completely visible. The car's speed had dropped from 77mph to about 57mph before I could press on the gas to resume normal driving. Had there been a car behind us, it's possible we could've been hit from behind. The car in the right lane did wind up passing us and I'm pretty sure they thought our driving was dangerous -- borderline insane. There were no warning sounds, no alerts on the monitor. It was completely random, completely sudden and completely dangerous. The car did this 2 more times before I disengaged the cruise control for the rest of the trip. I do not have a dashcam recording of this incident, but I do have one of a similar behavior from the car a few days earlier on July 13. It's hard to tell from the video exactly where it happens.

While using cruise control on an interstate road trip, the emergency braking system repeatedly caused the vehicle to slow excessively to where I was almost rear ended. This occurred approximately 15 times over a period of 3 hours. While traveling at 75 mph, the vehicle almost came to a complete stop on the interstate and almost caused accidents. There was no object in front of me or vehicle that should have caused the braking system to engage. Tesla owners call this “phantom braking” and after experiencing it so many times while on my road trip, I believe this is a very serious issue that needs to be investigated further. I do not feel safe using the cruise control any longer because of this issue.

The Tesla in vehicle navigation notified to turn the incorrect direction on to Canal Rd NW Washington, DC 20057 during one-way operation of the reversable parkway. The turn was notified from Clark Pl NW where there was no visual notification of the traffic being one-way. This culminated in a near head on collision in a 40 mph zone.

Can not use cruise control on my Tesla model three 2022 because a phantom breaking

We drove from Colorado to Minnesota and the car would phantom break while using cruise control. This happened about a dozen times during the trip. It would happen on an open road with no cars around. Very dangerous.

My car was set on navigate on autopilot, and normally it decreases speed when detecting change in speed limit. But for last couple of times, it's been not decreasing speed. On july 4th, 2023, I was driving and it did not change the speed limit based on the changes on the road. The speed limit had changed from 60 to 55, and it didn't change in the car. Also, Tesla just abruptly slowed down multiple times without any warning. There's no obstruction in the road, but it just keeps slowing down without a reason. Like the speed limit would be 45, and it's slowed down to 20. The car ahead is faster, and no one is walking across. it's just random.

Phantom braking of vehicle consistently around: 1. Emergency vehicles when driving in lane next to emergency vehicles flashing light. 2. Digital maintenance signs set and flashing messages on side of road. (Consistently when I pass a particular sign on a particular highway).

The car, on 6 occasions, rapidly decelerated while using the Autopilot feature when no obstruction was present. This was on the freeway, on a sunny afternoon, and seemed to occur at random without regard to overpass shadows, hills, etc. This nearly caused a collision from a car following me on one of the occasions.

I was driving on Interstate 25 north towards Santa Fe NM at about 75mph with the cruise control engaged. The car abruptly slowed down to about 60 mph for no apparent reason. The slow down was so quick that passengers were pushed forward in their seats. This has happened before when cruise control was engaged. I had hoped that this was resolved by Tesla. There was not any vehicles in front of me for the car to believe a slowdown was necessary. I reported this to Tesla for repair and they replied that a repair was not necessary. They gave me instructions to override the action by pressing the acceleration pedal. I don't believe that is the solution to the problem and fear that if another car was following to close behind me that an accident could have happened. This car was purchased with cruise control but I cannot utilize it for fear of this braking problem

"Phantom braking:" Vehicle has braked Multiple times on the freeway while using adaptive cruise control, when no objects were In the vehicle's path. Typically occurs when driving on curved section of freeway at speeds above 50 mph.

My car engaged the automatic emergency braking (AEB) when the car in front of me lightly tapped on their brakes-- When the AEB engaged, my car come to a complete stop... I tried to accelerate to prevent being rear ended, but my accelerator was disabled and I had no control of my car... Nearly causing me to get rear ended and probably causing a 5+ car collision. MANY Tesla drivers have experienced this, and it is absolutely TERRIFYING and NEEDS SERIOUS attention because lives are absolutely endangered due to this, and Tesla will not take responsibility, nor have they acknowledged the problem, at all. I've had this happen several times in the last week and I am just waiting to get in an accident at this point. This is unacceptable.

While in cruise control the vehicle initiates braking rapidly for no reason. This happens at high speeds 55, 65 and 70 mph on clear roads. No vehicles in front of or coming from the other direction. There may be vehicles behind at times. It doesn’t happen all the time but happens enough to be a concern.

On multiple occasions (100+) during a 4,000 mile road trip, (May 7-26, 2023) this vehicle slammed on its brakes while driving down the highway while using the adaptive cruise control feature. Speed reduction was up to 25 MPH from highway speeds of 65 - 80 MPH. This braking was quite dramatic, just short of locking the brakes up. Traffic conditions varied from very light (no vehicles in sight) to moderate traffic (vehicles in front, in rear and/or to the side). Weather was mostly clear, roads were mostly in good shape, there were no animals, people or other non-vehicle obstacles noted. Several instances were lodged in the vehicles "bug report" functionality, but not all, so Tesla should have a pretty good record of the status of the vehicle when several instances occurred. On more than one occasion we were very close to being rear ended because of this phantom braking. In contact with a Tesla Service Center, we were told this is a known issue but no fix had been found.

During a 30 mile trip on a two lane highway I activated the cruise control. A number of times the car made significant slow downs. They seamed to be associated with oncoming trafic. I then shut off the cruise control. Later on when I could see there where no oncoming cars I again set the cruise control for 65 MPH. After only about 15 seconds the car made a rapid deceleation. The deceleration was rapid enough to cause an ice chest sitting on the passangers side of the front floorboard to roll over. I shut of the cruise control and did not use it again for the remainder of the trip

While driving in cruise control, NOT AUTOPILOT, my car phantom braked. The road was clear, the weather was clear. I'm thankful there was not a car behind me. I was doing the speed limit at the time 70mph when the incident occurred. the date lised below is an approximate date. It has occurred several times. I drive 45 minutes to work Mon-Thurs and cruise control helps for the long drive

Trip to California and back from AZ. Had several instances of severe braking. If I did not press the accelerator immediately, the car would slow down under what seemed like nearly maximal braking. No reason was apparent for this behavior. Some braking instances were on long straight stretches of I-40 with no other cars visible. This issue was only occurring if I had the cruise control engaged. Under normal daily driving without cruise control this issue of emergency braking does not occur. Each time this happens, it is totally unexpected and is extremely disturbing. I have stopped using the cruise control function on the vehicle out of fear of it causing an accident.

CAR HAS PHANTOM STOPS ON CRUSE CONTROL THREE TIMES IN SIX MONTHS

While driving on the highway at highway speeds, our Tesla Model 3 frequently will perform a phantom braking action, presumably due to incorrectly sensing a collision. Thankfully, so far the traffic has been light on the freeways. Otherwise, this could’ve easily caused a wreck. This has happened to us approximately 20 times in the past two days. We ensured the sensors are free of any dirt.

The contact owns a 2022 Tesla Model 3. The contact stated while driving approximately 80 MPH with the cruise control set at 80 MPH, the vehicle independently slowed to almost a complete stop. The contact stated that she pulled the vehicle off the highway. The contact stated no warning light was illuminated. The contact returned the vehicle to the highway and engaged the cruise control and set the control to 80 MPH; however, the vehicle failed accelerate to the designated speed. The contact stated that the inadvertent phantom braking failure recurred. The contact turned off the cruise control and continued her trip. The contact had taken the vehicle to a local dealer, where it was diagnosed, and she was advised that the manufacturer was aware of the failure but a remedy was not yet available. The vehicle had not been repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 9,000.

When we're traveling on the highway at 55 mph plus and have cruise control engaged, the car will unexpectedly and suddenly brake for no reason. The problem is happening more often. This has even happened when there are vehicles behind us, but thank God they were not following closely. We may end up with whiplash, or worse, being rearended. We have complained to Tesla at least 3 times since February 2022 about this problem. The first time, they changed the front camera and said they thought that might help. It didn't. The next time, the service dept. said that there was no fix for the problem, but Tesla was working on it. Most recently in April 2023, the service tech., said there was no fix and he did not expect that there would be one anytime soon. This is unacceptable.

When driving on a vacation and on a highway from Tucson, AZ to Laughton, Nev we experienced what is being called PHANTOM breaking traveling approximately 75 mph several times. Extremely lucky to have not been rear ended. It also has happened with the FSD Beta late last year when I leased the software for a month. Can supply dates.

Adaptive cruise control fails. Repeated phantom braking on the highway. Would cause severe high speed accidents if there was traffic, luckily there was not. Not yet. Not yet. No. First appeared on my first long (5+ hr) road trip and brakes were applied jarringly for no reason, braking from 80mph down to 55 before I could turn the cruise control off. Repeated this more than a dozen times on the highway.

Hello, I recently drove 600 miles and experienced numerous random, frightening and dangerous occurrences of "phantom braking" while in cruise control mode. The car suddenly slammed on the brakes (I could hear the tires screech) while the highway was almost always completely empty, and always completely devoid of any potential danger. In three occurrences, the car was confused by something physical (albeit posing no danger at all): it was confused a "divide highway" sign post at the beginning of a divided highway median, the distant back a truck, a least a quarter of a mile ahead, and an incoming truck a least a quarter of a mile ahead in a long curve. In all other occurrences -the vast majority of occurrences- whatever triggered "phantom braking" was nowhere to be seen (the highway in front of me was completely empty of any traffic or obstructions), and never materialized. My safety and the safety of drivers behind me (and potentially in other lanes in case of a pile-up) was compromised during every occurrences. I stopped using cruise control when a car or truck is behind me. I contacted Tesla Service. They did an over the air check and said that there was nothing wrong with the system, that each occurrence provided data to improve the Beta system (it would have been nice to be told when I purchase the car that my family and I were Beta testers of an automotive safety product), and that Tesla is "working on a firmware update". Not very reassuring, and most importantly, no fixes at all to address this dangerous safety issue. Tesla Service indicated that I do not need to bring my car in (since there is nothing wrong with the software and therefore no fix).There was no advance warning before occurrences of "phantom braking". Thank you.

I was driving my car north on I15. Suddenly the car applied full breaks when there was no objects on the road. I could no longer control the car. Even when my foot was on the accelerator the car automatically depressed the break pedal. Luckily there was no vehicle behind me. I was also fortunate that we were going on a straight section of road. If this happened mid turn I would have completely lost control. These cars are a danger to society. It is impossible to drive them safely when they take control away from the driver.

While driving across the Nevada and Utah deserts, while on cruise control, traveling at 80 MPH we experienced 7 phantom braking. There were no vehicles or obstructions in sight and it was on straight stretches of road. We are no longer using cruise control due to the danger of possibly causing an accident.

Driving on the freeway at night, cruise control was on and going 70 mph. There were no other cars around and the car started braking on me out of no where. My speed went from 70 mph down to almost 20 mph on the freeway. Luckily there was no one behind me otherwise it would have been a bad crash.

I have had several incidents of my car rapidly decelerating when in assisted driving mode and I am driving on the highway. I am driving at 65 and all of the sudden it decelerates, making it extremely dangerous. There are no apparent barriers or nearby objects causing this to happen. I am very concerned this will result in a significant accident. I have filed this claim previously without anything happening. Additionally, I had a problem with my rear warning signal not going off when I was in a parking garage, causing me to back into a car. I filed a claim with Tesla and never heard back from them.

While driving on the highway on a clear day using what I call cruise control that also adapts to the speed of vehicles in front of my vehicle, as well as to extreme weather conditions, with no other vehicles around me, the car randomly decided to apply the brakes without provocation which slowed the vehicle from the setting of 74 mph to 49 mph before I could react and correct the aberrant braking. This is the 4th time this has happened in this vehicle. Previous incidents occurred in heavier traffic, so I suspected the aberrant breaking was an overcorrection relative to the other vehicles around me. After this most recent occurrence, I am confident there was no other reason for the car to suddenly brake other than due to a fault with the car.

The Tesla computer and especially the USER INTERFACE IS UNSAFE. More accurate to say I hate the UNFRIENDLY user interface. I am surprised NHTSA OKed this computer interface. It needs a GOOGLE quality voice activation feature. The current one is deaf to most words normally used to drive a car. E.G., to turn the lights on while driving on a road where “LIGHTS ON” is required. I must hit a button to see all controls. Then I must hit the “LIGHTS” button. Then I must hit the “LIGHTS ON”. All this while having trouble reading the small print on the screen. The reading is difficult. All this while taking my eyes off the road to even see the screen. This is just one of very many examples. The actual use of the computer is VERY OFTEN more user UNfriendly and UNSAFE than the “LIGHTS” button. Dangerous, DANGEROUS. I almost killed another driver when my car was new because I was WORKING the computer and I ran a read light. Fortunately my car stopped because I hit the breaks or because the car was, in fact, SMART??????? I am surprised NHTSA OKed this computer interface. The computer is smart but using the interface is dangerous. I want to bring this issue up to NHTSA, not to issue a recall, but to ADD on a user interface as good as GOOGLE? What is the chance that they will re-investigate a safety decision they have already made?

Our 2022 Tesla Model 3 has "phantom braked" three times on the highway. During each episode, the vehicle slowed from 75mph to 45mph in about half a second - with no vehicle or obstruction in front of us. This was a 4-lane highway all three times. If a car was behind us, it likely would have collided with us. No precipitation, the car was clean and cameras clear. I took the car to the Latham Service Center at 326 bOld Niskayuna Road near Albany, New York, to have the sensors and car checked. The tech took the car for a 10-minute drive, didn't experience phantom braking, and said that since he "could not duplicate the concern" no repairs were needed. After several messages expressing concern that this did indeed need to be fixed, neither the owners Scott and Carolyne nor the tech responded.

Nearly every time I use the "Traffic-Aware Cruise Control" on my Tesla, I experience a phantom braking event. Nearly all the time it is when the road is clear, in the daytime. I use this feature infrequently because I cannot rely on it at all and I'm concerned it will cause someone to hit my from behind.

Just completed a 3 day cross country trip from Palm Desert CA to Saint Paul MN. On a long highway trip like this, we rely on 'cruise control' to maintain consistent highway speeds. Tesla provides adaptive cruise control as a feature of Autopilot. On numerous occasions, the adaptive cruise control unexpectedly stopped, causing the vehicle to slow, or unexpectedly braked hard causing the vehicle to sharply reduce speed. Due to the frequency of Tesla autopilot phantom braking, I found that my foot needed to consistently hover over the accelerator pedal to counter the numerous instances of phantom braking. This was necessary to prevent a possibly inattentive driver behind the Tesla from driving into the rear of the Tesla or another vehicle driving behind the Tesla. This phantom braking occurred as many as 6 to 10 times per day over 3 days and approximately 2,000 miles. The adaptive cruise feature malfunctions under certain conditions and our vehicle is available for inspection upon request. Our safety and the safety of others was put at risk by unexpectedly slowing or braking hard while driving at posted highway speeds and putting our vehicle at risk of being rear ended, and perhaps the same for a vehicle behind our vehicle. The phantom braking issue has been well documented in press & social media and I find it difficult to believe that it has not been reproduced by an independent organization such as NHTSA. I believe that the manufacturer (Tesla) is aware of the phantom braking issue as it appears to be inherent to Tesla's approach to providing adaptive cruise control. When the phantom braking occurs, there are no warnings or messages prior to the unexpected braking. Most phantom braking instances occurred on approach to or on the crest of a hill. At least one instance occurred after cresting a hill and the roadway was in full view.

complete shutdown or blanking screen while driving causing GOD knows what is working and what not. definitely driver won't know his/her speed, car systems status like blinker, auto pilot,...etc until the system comes back to become available. 1st time this happened, Tesla sent me its service mobile service person who mentioned that he could not find anything wrong and if it happened again he will schedule the car for an in-house service center appointment for the main computer unit to be replaced. When the incident happened again Tesla scheduled the service appointment but after inspection the report came back that this is a recurring incident in many teslas and require a firmware update! Service report attached (Job number 4 and 5)

Vehicle will repeatably go incorrect speed limit while on Autopilot or Fsd(beta), internal mapping data has incorrect speed limits, sometimes 65 in a 30, other times 25 in an unmarked 55. Speed limit may change multiple times within a short distance making it hard to correct without slowing or speeding up This is on software 2022.45.12. ( fsd 11.3.3), has been a constant issue on previous versions, also affects regular auto pilot

On a two lane road with no traffic approaching and no traffic behind us on us95 in the Nv desert, the model 3 slammed on the brakes and slowed from 60mph to 30 or less. This is with the adaptive cruise control engaged, not auto steering. This happens several times. There were several times when large semi trucks were approaching in the opposing Lane and the model 3 slammed on the brakes also when adaptive cruise control was engaged. When we reported this to Tesla they said they need the exact date and time of each incident, or they could not help us. These breaking incidents happened during a 12 hour trip between Carson City and Rancho Cucamonga. This is an unbelievable safety hazard as if someone is following too closely and the car suddenly decide to apply the brakes. The person behind you is going to be caught off guard and crash into you. I cannot believe this is been going on for over a year as I have read several articles about the problem. There is no warning whatsoever when the car does this.

During normal operation vehicle suddenly engages braking system l. This has nearly caused 2 accidents. Tesla insists there is no fault with the car.

With the autopilot engaged, on the freeway, and at freeway speeds, the car will automatically brake without reason and without any traffic in front of the car. In a stretch of 100 miles, the car did this 8 times. The car even "phantom brakes" on regular cruise control. This is not only alarming but dangerous! Had the road been wet, or slick, we could have easily crashed! THIS MALFUNCTION NEEDS IMMEDIATE ATTENTION! Thank you, Steve & Liza Starr

While using autopilot the car randomly decelerated from 75mph to almost 30mph in the highway (I75) super quickly. If a car has been behind it might have caused a crash.

I used Autopilot on my Model 3 for the first and only time a few weeks ago, and had a terrifying experience with "phantom braking" that could have killed my entire family while going ~75mph on the I-5 near Bakersfield, CA. The I-5 here is split with 2 lanes in each direction, and is straight with no bends. I was driving in the right northbound lane, with Autopilot engaged (adaptive speed control only, no automatic lane-steering). My right foot was off both pedals and two hands were on the wheel. There were no other cars in sight except for a single car driving northbound behind me in the left lane. This car began to pass me on the left, and when its front bumper was aligned with the mid-point of my car (I could just barely see the front bumper through the corner of my eye), my Tesla suddenly automatically slammed on the brakes with absolutely no warning! I immediately clenched the wheel as hard as I could, and had to quickly respond to prevent the wheel from automatically veering to the left. While fighting the wheel to try to keep the vehicle straight, and my family hanging on for their lives, we screeched to a grinding halt at a 45 degree angle facing the left lane. We were extremely lucky to not hit the passing car and fortunately there were no vehicles behind us. I disengaged Autopilot and quickly got out of there so we weren't vulnerable. I speculate that the camera on the left panel between the driver and rear door saw the passing car, and wrongly invoked automatic evasive braking and steering maneuvers in response to a falsely anticipated head-on collision. That's the only reasonable explanation I can come up with. I will not use Autopilot again until "phantom braking" is eliminated. This is a known issue that I've since found mentioned all over the Internet by other Tesla owners. This needs to be fixed hastily before people are killed! We're damn lucky I had both hands on the wheel, otherwise we'd likely be dead! Note: Same report has been sent to Tesla.

Since taking ownership of vehicle in summer 2022, have experienced multiple incidents of vehicle emergency braking for no apparent reason while using cruise control. In a few instances when I have attempted to use cruise control again after initial phantom braking incident, there is a 2nd incident of emergency like braking for no apparent reason in the same trip. Have never attempted to reuse cruise control within same trip after experiencing issue twice in that one trip. When phantom braking occurs: - It is while using cruise control (with or without steering assist). - There is no audible or visual warning (not even from auto emergency braking system) before or during vehicle braking. - Is a very strong braking force akin to an emergency maneuver. - There is no clear reason for why vehicle braked - no obstacles in road or slowing traffic. - Level of traffic (light or moderate) does not seem to be a factor, but I don't use system in moderate to heavy traffic. - Weather does not appear to be a factor - it can occur in perfect driving conditions (sunny, clear day). In most recent incident, was traveling at 78mph on highway with no traffic in front or behind vehicle for approx. a half mile in either direction. Without warning or reason, vehicle began to brake hard, slowing vehicle down to 62mph before I could disengage system (approx 1-2seconds). Unclear how low vehicle would brake to if cruise control wasn't disengaged. Cruise control feature feels extremely risky to the point that view as unusable in almost all driving situations (even if would be a good time to use cruise control).

The contact owns a 2022 Tesla Model 3. The contact stated while her husband was driving 80 MPH with the cruise control activated, the vehicle jerked forward and decelerated to 52 MPH. The contact stated there was no warning light illuminated. The driver deactivated the cruise control and continued driving to his destination. The contact stated she also experienced the failure on February 27, 2023. 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 1,000.

While in the cruise control mode my car will periodically come to an abrupt slowdown. Often when I’m on the freeway and I am very concerned that one day I will be rear ended by the cars totally unexpected slow down. It has happened at least 30 times in my Tesla model 3

The "traffic aware" cruise control automatically slows the car when entering a portion of highway with a reduced speed limit. Sounds good in theory and Tesla says this is intentional and cannot be modified in settings. However, suddenly slowing down from 65 mph to 45 mph when all traffic PERSISTS at 65 mph could lead to rear end collisions or loss of control.

The car suddenly braked for no good reason nearly caused an accident.

Constant Phantom Breaking at interstate speeds. Tesla insists this is not a problem.

On my morning commute to work, while using ADAS equipment, vehicle swerved harshly to the right from the right lane in an attempt to take an exit off the highway even though I had not signaled an intention to take the exit. Then, while on a straight, clearly marked highway, vehicle “phantom braked” harshly 3x even though there were no obstructions or cause for hard braking. There were no other vehicles in front of me or debris/items in the road. This sudden braking has become more common and could pose a safety risk to other drivers or cause an accident if my vehicle were to stop unexpectedly. Windshield was also clear and there was no fog/rain/or other conditions that could impede ADAS camera operation.

Cruise control thinks it detects a pending collision and abruptly brakes. Following cars almost rear ended us. This happens every time at exactly the same bridge overpasses on the NJ Garden State Parkway south.

Phantom braking while using Autopilot caused quick and static loss of speed on the interstate, which could easily have resulted in an accident.

I was on I-15 in Utah on 1/29/2023 appoximately 2:00. I was attempting to pass in the left lane so the cars behind were following quite closely. I entered into some Snow Flurries and the car hit the brakes. I barely avoided a 3 car pile up because of this behavior. It appears that this feature for Emergency Braking encountered a false Positive which my family and I barely survived.

Drove a 2,000 mile road trip on exclusively divided highways, I-25, I-40, and US 287. Sixteen times (average once per 125 miles) the car braked hard when the adaptive cruise control was on, twice dropping from 75 mph to 45 mph. Any of these incidents could have caused an accident if someone was following closely and was not paying close attention. My notes suggested that the vision-based system braked for a billboard well off to the side of the road on a curve, reflective road mirages twice, a bride once, and for no reason I could identify the remaining times. Tesla asserts that the adaptive cruise control is "Beta." It's not clear to me that they intend to correct this terrible behavior. Sadly, the car deleted its video files of the incidents and I was not able to recover them.

This vehicle along with many tesla vehicles has issues where it will randomly brake when in Autopilot mode going from sometimes high speeds such as 75mph trying to force the car down to as little as 35mph in a very fast manner, causing an increasing concern for vehicle collisions. As well as the automatic wipers not functioning properly and operating too fast when there is no precipitation as well as too slow when there is precipitation causing a potential visibility issue.

I was driving eastbound on I-8 from San Diego, AZ towards Yuma, AZ and making use of my Tesla Model 3's adaptive cruise control feature when my vehicle suddenly and without warning slammed on its breaks. No warning or error messages were displayed on my screen – it's as if the vehicle thought I was on a collision course even though I was not. I was in the left-most lane and the vehicle behind me was dangerously close to colliding with me, but I was luckily able to step on the accelerator pedal and regain enough speed to avoid an accident. Though there was no accident, this incident has severely under-minded my trust in the feature.

Phantom braking caused by Autopilot. Car slowed down quickly and could have potentially caused an accident.

Phantom braking on the interstate. Autopilot causes the car to slows down significantly and quickly, which could potentially result in an accident.

Full Self Driving does not perform as advertised. Will not take Interstate exits, nor will it safely merge into traffic. There have been numerous phantom braking occurrences. This feature has been misrepresented numerous times by Tesla.

My car will randomly slam on the brakes when I’m driving on adaptive cruise control even when there is not a car/truck/anything in front of me. Seems consistent in description to what others have termed “Phantom Braking”

Ghost forward collision warnings appear from time to time even tho there is no one in front of the vehicle. Sometimes when the vehicle in front of me is turning left/right the collision warning will alarm me of possible impact even tho there was no real threat for anything to happen. Also, it happens when you want to park behind a parked vehicle (it happened to me today) and alerted me of a possible crash, while i was crawling to park. I wouldn't mind these ghost warnings, but since I am using Tesla Insurance which gives monthly insurance premiums based on the safety performance of the driver (FCW is one of those and the most important one) this is always impacting me financially at the end of the month. Tesla should be forbidden to use a technology that is not perfect in order to determine the price of the insurance.

On a recent trip (December 22, 2022) from Twin Falls, Idaho to Boise, Idaho, my Tesla model 3 braked without warning or any other reason while driving on the Interstate. The Tesla was in adaptive cruise control at the time and appeared to brake for no apparent reason. The braking was significant enough that it would have caused someone traveling behind me to collide into my rear-end without siginficant avoidance (and attention). This occurred three seperate times until I deactivated the cruise control. I felt it was not safe to operate with moderate to heavy traffic. I love my Tesla and feel it is one of the best vehilces I have owned; however, phantom braking is a significant problem. It needs to be corrected by reintroducing radar or some other technology. I have never experienced this with my other vehilce (Toyota Tacoma).

Phantom braking repeatedly occurring while using normal adaptive cruise control (Autopilot). This has even occurred with no near traffic and no shadows or other irregularities in the road ahead.

We have regular phantom braking issues. This has been happening since we got the car new. I have videos. We have nearly been rear ended twice and this has happened before n almost a daily basis. The problem has been reported to Tesla and of course they say “nothing is wrong with the hardware” and won’t fix anything. This is a well known issue. It’s gotten worse. Slamming on the brakes for what appears to be a shadow or perhaps a tar strip and sometimes nothing but concrete pavement. It’s really scary and dangerous.

Driving across Texas, cruise control with traffic assist was enabled in the 2022 Tesla model 3 long range sedan. The vehicle suddenly braked and went from 84 mph to 68 mph in a matter of seconds. There were no cars in sight, no weather conditions or obstacles around the highway. Unsure of what or why that happened the first time, cruise control was re-enabled and the same thing happened very shortly after re-engaging cruise control.

The contact leased a 2022 Tesla Model 3. The contact stated while driving approximately 70-80 MPH with the cruise control activated, the vehicle experienced phantom braking. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was 38,000.

To Whom It May Concern: Been meaning to submit this complaint for a while but have not had the time until now. My issue regards ‘phantom breaking’ related to Tesla’s TACC (Traffic Aware Cruise Control). Whenever I take long road trips on the highway and attempt to use TACC, the car will invariably hard brake on its own without reason or warning, even when there are no cars, animals, or other objects nearby in either direction. When this occurs, it is incredibly scary. If there had been cars close behind me, I have no doubt they would have rear ended me. It also causes panic to my family and baby, as the breaking is sudden and hard. As a result, I do not use the system when driving which means a tired foot for long trips. I know this is an ongoing issue, and the NHTSA is aware of it. I’d like to ask that the government REQUIRE Tesla and (and perhaps other car companies with similar challenges) to offer standard ‘old fashioned’ cruise control as an option for those customers that want it. Because Tesla’s TACC doesn’t work, I personally would just prefer to be able to set the speed on highways and then be responsible for slowing down and taking it off when I deem it to be appropriate. Being forced to rely on a Tesla’s faulty system is paternalistic and removes an important choice from drivers. Ultimately it is not safe. Please help change this.

Suffering from phantom braking even when all safety options turned off. This occurs even when just using standard cruise control. Very dangerous to the point do not feel safe using cruise control.

While driving the car suddenly the car applied sudden breaks & moved opposite road. luckily no traffic opp side otherwise we are having the same day as last day.

Tesla model 3 year 2022, making too much noise while driving noise.

while driving on north on I79 with auto cruise / steering on, the car tried to stop by itself at a speed of 70mph....almost causing the cars behind me to re-end me...this is the 4th time the car has had a phantom brake issue at speed...very scary and very dangerous

During cruise control on straight highways with no other cars nearby, the car would brake for no reason. Very scary.

I did not have cruise control on but do have the full self driving car simulation on. I believe that had I cruise control on that a rapid speed change could have occurred. While driving in Indiana, the car recognized state highway signs as speed limit signs. For example, on a couple of occasions, it changed when seeing a highway 25 sign but changed a few seconds later when it recognized the 55 mph sign. While in Illinois, it changed its notion of the speed limit for speed limit signs that were only valid when flashing. The firmware number of the car is 2022.36.20

We have experienced many instances of ‘phantom braking’. On a recent trip from St George, UT to Salt Lake City, UT (about 250 miles) we had eight instances going 65-80 mph.

I was driving on US interstate I-44 in Missouri at 74 miles per hour. I was using adaptive cruise control and not autopilot, when for no reason at all the car slammed on its brake and started slowing down at a fast rate. I had to push the accelerator to the floor to make it stop slowing down. If there would have been someone behind us we more than likely would have been in a serious accident.

Phantom braking. Driving down 395 going the speed limit, no other cars or any obstacles in the road whatsoever, the car would slam on the brakes hard to the point I almost lost control of the vehicle. This happened 3 times in a row before I turned off adaptive cruise control. This is the most glaring obvious example of a vehicle safety hazard that should be recalled that I’ve ever seen on a new car. If someone was driving behind my car I have no doubt this would have caused a rear and accident.

After purchasing my Model 3, I have experienced numerous times of what they call "Phantom Braking" and have tried to have it repaired and have been told that there is not anything Tesla can do at this time, but inform the driver to be aware! I was never told/informed/warned about this issue when I ordered and picked up my car. I have almost been in accidents at least 3 times while using my cruise control on the interstates.

While driving with Adaptive Cruise control on a two lane highway, as I was entering a curve in the highway and there was another car in the opposite lane, my Tesla rapidly decelerated to the point that it almost caused an accident. The car following me had to slam on their brakes to avoid hitting me. I just learned that there is ongoing deceleration problem with Tesla's and don't feel it is safe to drive with this technology on.

Regardless of which cruise control function you are operating in the system will suddenly brake for no reason, sometimes slowing down by only a few miles an hour and sometimes by as much as 30 or 40 miles per hour. This can potentially lead to a rear end accident. System has far fewer failures at night than during the day and far fewer if there is traffic in front of the car than if there is an open road in front. This cruise control is almost unusable during the day on an open road. This has happened within 45 miles of owning the car to present 5000 miles + and has happened at every speed we have used it at This has been an on-going issue since the day we bought it and not something the Dealership tells you about in advance

Experiencing phantom braking at high speeds when there is nothing there. This has happen 5-6 times during a recent road trip of 1000 miles

since ownership phantom braking has occurred while the adaptive cruise control, autosteer and/or autopilot have been engaged. IT is completely random and occurs at both high speeds and during local street speeds. It doesnt matter the terrain either. It has happened while on a straight and even road as well as curvy and rolling hills. It also doesnt matter if its daytime or night. The applications will also disengage (turn off) if the rolling hills are frequent.

While driving back from San Antonio TX, I engaged autopilot on the hwy. Multiple times my vehicle would experience phantom braking with no other cars on the road and would slow down drastically from 75mph to 20mph. This sudden braking for no reason could have caused an accident if there was another vehicle behind me. This phantom braking has also negatively affected my safety score for my insurance.

My car is brand new. When in Autopilot mode (not full FSD), the vehicle does u expected braking apparently randomly. There are no road obstructions or potential road obstructions visible at all to me as driver. Yet, the vehicle will brake suddenly. It does this so frequently that I no longer use Autopilot unless I know the road has no other vehicle driving behind me and is very clear ahead of me. I never, ever use it on the highway. In one incident, I was using my Autopilot and a motorcycle was traveling at a much too close distance behind me on a curve on a busy roadway, with a large RV driving in the lane next to me. As all three of our vehicles approached the curve in this cluster, my vehicle suddenly braked and the motorcycle behind me almost crashed into my vehicle’s rear end. It was terrifying. After that incident, I severely limited my use of Autopilot and take pains to ensure my foot is resting on the accelerator in case I need to apply a little pressure to counteract the unexpected braking while in Autopilot mode.

Multiple times traveling on Interstate 70 at 75 mph the car would brake itself without warning while the “Autopilot” (driver assist) was engaged. This probably happened 4 times over the course of 1 hour. I recalibrated the cameras after the 3rd event, but it did not help. This was very dangerous and unsettling. I verified no-one was close behind when engaging the autopilot in case the system “decided” to brake unexpectedly. If someone was behind me traveling at interstate speeds, they would have hit me.

Even with all automated safety options turned off, autopilot (cruise control) continues to implement sudden periodic "hard braking." This is occurring (a) when a vehicle crosses in front of my path *far* ahead of me, is not remotely close to causing an accident, and the way will be clear with plenty of room to spare by the time my car reaches that spot, and (b) sometimes for no reason I can detect: there's nothing in front of my car at all but open road. The second example above tends to happen at least once every trip in which I've engaged cruise control. This second case is especially startling and dangerous, because it seems to come out of nowhere.

Several times, while using the cruise control, the car automatically braked at highway speed. The car is available for inspection. My safety and my wife's safety were put at risk by the car suddenly slowing down on the interstate without my control. The problem has not been reproduced or confirmed by a dealer or service center - I have not had the car serviced. It has not been inspected. There were no warning lamps or messages.

The adaptive cruise control. is subject to sudden phantom braking. On several occasions when the cruise control is engaged the vehicle will brake for no reason. On one occasion the sudden braking caused a semi-truck behind me to swerve just barely avoiding an accident. On another occasion the vehicle braked so hard that we skidded. There is no warning when the phantom braking will occur. The adaptive cruise control is useless on two lane highways and streets, because it sees cars in the oncoming lane and brakes. I have called the company to have the vehicle check on at least two occasions. Every time I schedule a service the company calls back and tells me they know about the problem and that they are working on the issue. I asked if they could do an update to turn off the adaptive cruise control and revert back the standard cruise control that does not brake or slow down. They said that is not an option. This is a real safety concern, and I will not use the adaptive cruise control except in stop and go traffic. It has been my experience that there has been no phantom braking in stop and go traffic.

The car slammed on the brakes while we were using auto pilot on the freeway, even though there was no one braking in front of us. This was the 2nd time this has happened. The ac and radio shut off for the rest of the ride and the ac has been working intermittently since. We have a baby and she was not in the car but she is in the car with us often. We have submitted a service request for this week.

Everyday I drive on highway i-10 I get severe Phantom Breaking, when I have auto pilot on or just my cruise control. Sometimes it’s as hard as you can brake. 30+ mph before I can push the gas and stop it, with absolutely nothing around me, and all my software updates are up to date. Extremely unsafe and needs to be corrected.

Constantly issues with the car braking hard without reason - also the car NOT braking when needed, and poor estimation of distance to the vehicle directly in front. When the car Phantom Brake, it causes traffic behind the vehicle to become in danger of a forward collision. When the car incorrectly estimates the distance to the next vehicle, it causes the car to apply maximum braking force to rectify the miscalculation. The "Autopilot" and "Cruise Control" are dangerous and hazardous to use in normal vehicle operation. The vehicle/component and behavior is repeatedly certified as "within spec" and no issues found with the vehicle or components.

While using auto throttle (cruise control) on a recent trip I had several instances of uncommanded slow downs. These ranged from slowdowns from the activation of regenerative braking to actual hard breaking. It occurred on both two lane highways and interstates. More often on two lanes. Often it occurred on topping a hill and some thing in the distance was misinterpreted as a hazard. At other times I could not determine what set it off. It ranged from a slight slow down to hard breaking. It could easily have led to a rear end collision had someone been close to me. I finally had to stop using the auto throttle as it seemed unsafe.

I was using the adaptive cruise control and experienced phantom braking.

Cruise control set @70 to 74mph on open highway with no vehicles in front or behind. Midday, sunny, clear, and dry. The vehicle suddenly applies brakes. This could have easily lead to being rear-ended if another vehicle were following too closely. This happened numerous time this last weekend. Contacted the manufacturer and they stated this is normal and no hardware faults were detected in the vehicle when diagnosed remotely.

With Tesla Auto Pilot engaged, I was driving on I-10 in Florida with no other automobiles in front, to the side or behind my car. I was driving the 70 MPH speed limit when suddenly my car applied full braking (Phantom Braking) upon which I took control and applied the accelerator to regain proper velocity disabling Tesla Auto Pilot. This was the only time I experienced this issue.

i was driving through an intersection in san francisco on a green light and the car suddenly braked hard with no object in front of me to brake for. fortunately the car behind me managed to brake without rear-ending me. this was totally without warning and completely unneccesary. this was a "safety feature" that engaged to make me and the pedestrians and cars around me less safe! if the automatic emergency braking doesn't work (and is more dangerous to human life and property when activated as opposed to not), it should be able to be disabled for safety's sake. i can disable it for a trip, but then i have to remember to disable it every time i drive the car or it could put my life in danger! this is dangerous! the control panel informed me that the automatic emergency system was to blame for the dangerous stop. there was no warning before this happened. the vehicle has not been specifically inspected for this issue, but this appears to be a known issue for this model of car.

I drove from Denver to Amarillo using the cruise control. About 25 times the car braked hard for no apparent reason. Most incidents were a sharp 5-6 mile per hour drop. Three were a 15 mile per hour drop. I believe that roughly 15 of the incidents were the car responding to the optical illusion of shimmering water. This happened on the afternoon of September 28. It was a clear, sunny day with only occasional clouds. After sundown the hard braking on cruise control continued at a lower rate with 5-6 incidents between Amarillo and Vernon TX. If someone had been following too closely in any of the incidents it's likely they would have struck my car from behind. This cruise control is unsafe.

Have owned this car for one month now and have put approximately 2,500 miles on since its purchase (2 miles on odometer at pickup). When using Adaptive Cruise Control or Autopilot the vehicle will apply hard braking without reason and seemingly random. No oncoming cars, no cars in front or to the side, road is paved and well painted. Speed would be suddenly reduced from 70mph to 30-35mph. This is a safety risk due to possibility of rear end collision by following vehicle. This event happened multiple (10+ times) on the 10 and 40 freeways in California and Arizona and on the 95 highway in Nevada as well as on other roadways. I have subsequently disabled Autopilot on my car and now avoid using Cruise Control as it is simply too frightening to use. I reported this to Tesla Service who advise that hardware-wise there is nothing wrong with the car and future software updates will improve the function. They advise that both Autopilot and Cruise Control are 'Beta' software. I could understand with their Full Self Driving and Autopilot that these advanced features may need further development but I consider Cruise Control to be a well understood and long-established vehicle function. They could at least offer both old fashioned 'fixed speed' Cruise Control along with their Beta Adaptive Cruise Control, but they provide only the Beta version. Beta software which is simply too scary to use!

Phantom breaking while driving down interstate.

The contact owns a 2022 Tesla Model 3. The contact stated while her husband was driving 50 mph on cruise control, the vehicle began to decelerate independently. The contact stated no warning light was illuminated. The contact stated they continue to experience the failure five to ten times on the first trip. The contact stated she also experienced the failure on 9/23/2022, while driving 80 mph on cruise control, the vehicle began to decelerate independently to 70 mph and deactivated the cruise control independently. The contact stated no warning light was illuminated. The contact stated the force of the deceleration caused the seat belt to retract and caused her to have whiplash and headache left side of her head. The contact did not sought medical attention. The contact continued to experience the failure while driving to her destination. The contact stated she experience the failure for a second time on 9/25/2022. 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 1,000.

We just went on a longish trip, covering a total of about 2,500 miles. While driving on interstate highways and using cruise control, the car would occasionally brake for no reason. The first several times it happened, the car braked mildly and we tried to explain it away. ("It must have seen the guardrail/traffic cone/butterfly," etc.) However, the last time it happened, with absolutely nothing anywhere near us to the sides or front, the car braked FREAKING HARD. I was driving, and it scared the $hit out of me. If the 18-wheeler behind us had been a little closer, we would have been toast. After that, we disabled the automatic emergency braking every time we started the car, and we'll continue to do that.

On our trip from San Diego to Sacramento yesterday 9/21/2022; while cruise control was on, the Tesla braked for no reason on 3 different occasions causing great alarm and emotional distress to all of us in the car. We were traveling at freeway speeds on the 5 north and thank goodness no one rear ended us when these events happened.

While going at 75 mph, no obstacles or cars ahead of us, on US30 W in Texas, the car applied a sudden strong brake (phantom braking) that almost caused a severe accident.

Multiple instances of rapid deceleration, i.e.; braking or regenerative slowing while at cruise speeds on my latest cross country trip.

The contact owns a 2022 Tesla Model 3. The contact stated that while driving at various speeds with the cruise control activated, the vehicle experienced phantom braking with the Forward Collision Avoidance warning light intermittently illuminated. The contact also stated that a warning chime would sound during the failure. The dealer nor the manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was approximately 50. The consumer stated that the dealer was notified of the failure. The dealer informed the owner that the failure could not be repaired and that it was due to a poor GPS tracking. The consumer received a text from the dealer stating that the issue was "resolved remotely" but that is incorrect. The vehicle continues to have phantom braking issues.

My Tesla Model 3 has had multiple instances of phantom braking while the autopilot/cruise control has been engaged. All have been on the highway traveling 70-80mph. My car was delivered on 9/9/22, new from Tesla. I feel this is extremely dangerous at any speeds, but especially at highway speeds.

I rented a Tesla model three and have driven 5000 miles on it since I got it three weeks ago. In that time this car has done some very dangerous things that concern me about my safety. I stopped using the auto pilot function after one time when it tried to pull me off the road at highway speeds into the emergency lane. I have also started experiencing the phantom braking issue that you read about online. For some reason this car can’t go more than 10 or 15 miles without slamming on the brakes even though there are no cars anywhere close to me or any objects on the road that might trigger the automatic braking. I am afraid that this car is going to slam on the brakes when there is somebody behind me and cause an accident.

We have an ongoing issue with our Model 3 stopping for no reason at speed when using cruise-control or auto-pilot. We have had the car in for service at Kearney Mesa and the “manager” observed it happen. But nobody gets back to us and nobody knows anything. The car suddenly brakes for no reason. This happened multiple times. Including once with the “service manager” in the car. Answers below are for that occurrence. No other warnings on the display. If a car had been behind us, we would have been rear-ended. We are being “stonewalled “ by the attitude “I know nothing” or “someone will get back to you”. I cannot get through to anyone at Tesla HQ and the local service center is completely unhelpful. Please advise.

During recent drive from the Kansas City area to downtown Denver over the period of September 11-12, I experienced what's known as "phantom braking" no fewer than five times along I-70. At least one of these instances was so aggressive that it slowed the car down from 77mph to 60mph. This is an extremely dangerous situation that must be addressed by Tesla ASAP. Someone is going to die.

While traveling northbound on I-25 between Las Vegas NM and Raton NM, the car auto breaked several times for no reason,Going from 75 MPH to 57 MPH, throwing us forward against the seatbelts in the car. The incident Happens again between Colorado Springs and Cheyenne Wy and outside Cheyenne again on I-25 N. All incidents happened while using the cruise control, which is what Tesla recommends to get the most miles per charge. We are just very lucky there was no traffic behind us to rear end is.

On Saturday, September 3rd 2022, we were on a highway with Autopilot system engaged at 75mph, and without any reason, the autopilot system reduced the speed to 50mph, even thought the highway speed limit was not reduced/changes, there was no vehicle or event requiring the vehicle to reduce the speed, and the Autopilot settings were to keep the current vehicle speed limit. It was a sudden unintended braking action in Autopilot, which could lead the vehicle behind us to crash and a severe accident on the highway. The sudden unintended braking happened 2x during this road trip, without any warning or symptoms.

The adaptive cruise control, or traffic-aware cruise control (TACC) as Tesla calls it, phantom brakes with no prior warning a few times per hour. It usually happens on straight stretches of road when there isn't much traffic in front of the vehicle. The event that prompted me to write this complaint was when I was travelling on a highway in Utah. I was driving about 80mph slammed on the brakes and slowed to about 30mph. There were a few vehicles behind me when this happened. Thankfully they were able to brake in time to avoid a rear-end collision. I always drive with my foot on the accelerator with TACC because I experience lots of phantom braking, but this particular event happened too quickly to intervene. I have reported this to Tesla, but they claim it's normal operation of the vehicle.

Car will phantom break while using autopilot. I will be driving 80 mph on a main free way (I-80) and all of a sudden it will slam on the breaks and go to 40 mph.

During a road trip of around 600 miles when using the adaptive cruise control feature without autopilot active I experienced no less than 6 phantom braking incidents. Most were when coming over a crest of a hill. There were no warnings or indications on the instrument screen. During each event I had to press off the accelerator to stop the braking. The car resumed the set speed with adaptive cruise control active. During some of these events a car was behind me that could have either hit me or lost control of their vehicle and caused an accident.

While driving down our rural highway, with little traffic, the cruise control is basically unusable. The cameras see the heat shimmer on the highway (100 degrees plus) as another stationary vehicle and slam on the brakes suddenly and frighteningly. If there is traffic (rarely) in front of this, the sudden deceleration never happens. However, the traffic free environment causes this kind of reaction on a regular basis. On a 60 mile trip that we regularly make it happens enough in the first 10 miles that we don't use the cruise control again on the trip. We try again after each software update but this hasn't improved anything yet.

Often when driving on the highway with the cruise control on, the car will activate heavy braking without provocation. Sometimes it happens once on a 2 hour drive other times it happens 3 or 4 times on an hour drive. One time, I was the only car in sight when I was in a double lane 65mph divided highway. I am not using full self driving or auto steer, however it has occurred while using Auto Steer (beta). I'm not sure what causes this braking, but it's dangerous. One time it brake checked a semi truck before I slammed on the accelerator pedal to disable the braking system. Other times I can feel short choppy accels/decels on the highway again without having a car/object in front. Today a driver was following closely and it went into full braking mode. I'm not convinced it's emergency braking, however when you take your foot off the accelerator pedal it does brake heavily with regenerative braking. In our ownership of the car, the collision warning has chimed at us once but not actually activated braking to my knowledge. So far I've seen complaints about Full Self Driving autopilot Phantom Braking, however we don't have that package. However the same systems are physically installed that may feed into the safety systems.

The contact owns a 2022 Tesla Model 3. The contact stated while driving 70 MPH with the self-driving assist feature activated, the vehicle experienced phantom braking. The contact stated that the failure occurred approximately 6-10 times within 7 hours. The contact stated that the failure reoccurred 4 times within 4 hours while driving with self-driving assist and auto-steer mode the following day. The contact notified a Tesla Service Center who informed him to submit a service request online. The contact submitted a service request online and later received a remote diagnostic test report stating that no hardware issues were found and the vehicle was operating as designed. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 5,200.

The adaptive cruise control thinks that those heat shimmers/pavement mirages you get on asphalt are trucks stopped in the middle of the road and slams on the brakes. It happened dozens and dozens of times on my drive on I-80 from Reno to Colorado. It seems like this is a common experience from searching the internet. I will take it in for service but it seems like its happening to everyone so not likely to get fixed. Sometimes it will only slow down a little bit, 5 or 10 mph, but I've also had it hit the brakes hard and slow me down to 25 below the speed limit. Sooner or later this is going to cause accidents, if it hasn't already.

The car will dramatically, without warning, and unexpectantly brake while using the adaptive cruise control. This has occurred with absolutely no issue that should provoke the braking. One instance did occur with traffic behind me, which led to those vehicles having to emergency brake. I do note that this issue has been frequently reported and characterized as "phantom braking". It is real and it is a genuine risk and concern. I will report yesterday's incident, but it has occurred several times previously.

My Tesla model 3 has detected imaginary object while using auto pilot feature and applied FULL brake pressure to stop the car, which puts us in danger of being rear ended.

Several incidences of phantom breaking occurred when no other cars were around. This took place during our road trip from Michigan to Montana. One of the days, it occurred over 10 times, with the worst resulting in a hard brake from 75mph to 50mpg before I could intervene. The majority of the time there were no cars within 200 yards ahead or behind me. If there were a car behind me, it could have resulted in a severed accident. The braking was hard enough to throw me and my children hard into seatbelts, even causing the belts to lock. I reported these incidents to Tesla but have heard nothing back.

While driving using the autopilot system on a clear, sunny day with no traffic ahead or behind my vehicle, I had a Phantom braking incident causing my brakes to be applied in an unsafe manner which would have brought me to a complete stop had I not intervened by quickly stepping on the accelerator. I was moving along at freeway speed when this incident occurred.

I wish to report numerous cases of the phantom braking or spurious deceleration that I have experienced. In driving over 2500 miles on highways I have experienced this issue at least 40 times. It would be more, but I have stopped using it. Almost all cases were on mostly open roads through Kansas, Colorado and Wyoming. The odds of it happening appear to be higher when the road is hilly and another vehicle, typically a semi, is far ahead. Timing the distance, it looks like the semi is 12-15 seconds ahead of me in a 70mph zone. This creates a situation where I may be cresting a slight hill upwards while the semi is cresting the next hill ahead of me. That situation (just one example, others are more flat roads with no vehicles ahead) creates a distance challenge where the point between the vehicles is shorter than the actual distance, due to the hills. One instance slowed so quickly the tires squealed briefly. This feature, Traffic Aware Cruise Control TACC or autopilot, should never be used if another vehicle is following closer than 5-8 seconds behind. I have tried things to help the situation, such as making sure the cameras are clean and recalibrating the cameras with clearly defined lines and no changes have resulted.

Full Self Driving on this car experienced Phantom Breaking meaning it braked by itself when there were no nearby cars ahead of me. This is very dangerous as it can cause cars behind me to crash into me.

Experienced multiple episodes of severe phantom breaking when traveling over 60mph with adaptive cruise control on.

Driving with cruise control on two lane or interstate car will automatically just slam on breaks. Dropping cars speed 10+ mph. There is no warning it breaks hard enough to skid tires and lock seatbelt. I have several times it has break checked car that are behind me cause them to switch lanes abruptly. It will do it some times after you merge back into a lane after you pass some one. There is no warning at anytime it will do this. I reported this to them the day I purchased this car new. They canceled the service appointment and said car will update it self and there is a software issue they are working on. Car is getting worse as time goes on. It does it every time you drive it. I understand if it slowed down 1 to 3 mph but it will drop 20 mph in seconds. It violently brakes. You can hit accelerator pedal fast enough before it drops 10 mph.

Multiple instances of hard phantom highway braking on clear sunny days with no other vehicles close while using adaptive cruise control. If another vehicle had been following closely it could have caused a rear end collision as there was no cause to slow down. This problem is recurring. Tesla says to just report the incident on their automated system but there has been no response from them.

The contact owns a 2022 Tesla Model 3. The contact stated that while driving approximately 75 MPH with the cruise control activated, the vehicle abruptly reduced speed to approximately 35 MPH without warning. The contact indicated that no other vehicles or objects were nearby to cause the Forward Collision Avoidance system to be activated. The cause of the failure was not determined. The local dealer and manufacturer were not notified of the failure. The failure mileage was 7,000.

While using the Autosteer/ Adaptive cruise feature on a recent long trip multiple times while at speeds of 55 - 75 MPH the car aggressively applied the brakes almost causing an accident where an 18 wheeler was following closely passing another truck. The other times it occurred were on flat roads with no vehicle in front or on either side.

While traveling on a highway (~ 50 mph) I engaged the cruise cruise control. After about 5 minutes -- while no traffic or obstacle anywhere near me -- the car suddenly applied emergency braking bringing the car near full-stop in the middle of the highway. I am fortunate there was no one behind me or it would have resulted in a collision. Obviously it was a terrifying event and I have instructed my family never to use that feature.

We were using traffic aware cruise control on autopilot in Florida on our way back home from vacation, when st approximately 7:45am our model 3 suddenly slammed on the brakes on a very busy highway. We were almost rear ended, thankfully our quick response to take over and the driver behind us paying attention let us avoid a crash. Over the next 15 minutes the Tesla had one more phantom braking incident, thankfully we were ready as we no longer trusted it, then it began to reduce speeds to 30- 45mph saying that was the speed limit. The speed limit was 55 and 60mph. We have not experienced this problem until now but are very concerned about the safety of using autopilot or cruise control.

Over a 4500 mile road trip, I experienced about 75 emergency braking incidents that were not caused by anything visible in the road or due to conditions. In nearly all cases there were warning chimes, but not always. Most were at highway speeds and were a sudden attempt to brake which required me to immediately react by stepping on accelerator to maintain distance in front of cars or large trucks behind me. It seemed more likely to happen at higher speeds (70-85 mph) and often times in more hilly areas of highways and often times as well coming just over the crests of hills. Tesla reviewed logs and said they didn't see anything and have been unhelpful. This is a high risk issue if cars stop on highways and people are not able to react quickly enough. So

Cruise control engaged at highway speeed of 70 mph. Car applied emergency braking hard and slowed to 52 MPH. Road is 4 lane divided highway. There were no vehicles within a mile in front of car. There were no other obstacles on the road. Car did the same thing 4 other times under similar conditions. The way the car brakes on an unobstructed road can easily cause me to be rear ended. Speed control is not useable in this condition if any other vehicle is traveling behind. This is not an isolated Incident in my Tesla. It has happened multiple times on different roads in all environmental conditions. Todays event happened around 1500, bright sunshine, straight and flat road.

Multiple times, during a bright sunny day, I've been traveling on the highway, with no traffic around for a mile ahead, with cruise control on. There were times with no autopilot on, and times when it was on. The car slammed on the brakes, going from 80mph to 30 mph, and once the car realized there was no object on the road, it returned back to 80 mph, and kept going. This would be very dangerous if there was a car following behind me. This is "phantom braking". It has happened 10-12 times during a 200 mile trip, on divided, as well as undivided highways, with no traffic, and with oncoming vehicles in the opposite lane.

During a recent trip from San Diego to Tucson and back, I had several incidents, in each direction, of sudden deceleration/phantom braking when the Autopilot feature was engaged, while driving on the I-8 and I-10 highways. The first time it happened, the collision avoidance alert also went off with very abrupt braking. Each time, the car did not brake to a stop, bud did suddenly and quickly decelerate several mph. After a couple of incidents, I prepared to intervene by pressing the accelerator to counter the slowdown. I thought it might be the autopilot causing the issue, so I started using the adaptive cruise control only without the steering feature, but it happened once with only adaptive cruise control too. Altogether, there were about 4 incidents per direction of travel.

Phantom braking. The car had autopilot enabled and applied brakes to slow down even though there was nothing in front that would have caused a collision. Fortunately there was no vehicle behind otherwise it may have caused a collision.

Phantom braking!! This car is almost undriveable due to it “hitting the brakes so hard” so often… TESLA PLEASE!! Fix this!! I want “dumb” cruise so it doesn’t ever hit the brakes… I am going to get rear ended someday!! The car hits the brakes so hard that it actually leaves black marks on pavement sometimes when there is literally NOTHING on the road and it’s completely clear!!

I was hit by a woman driving a Tesla with autopilot turned on. The system did not detect the red light, and she hit the right front quarter panel of my vehicle, totally my vehicle. The autopilot system malfunctioned and should have detected both the red light and the collision which was likely to occur. To my knowledge, the vehicle is in the control of either the driver's insurance company or the Police.

When driving on a 4 lane divided highway using adaptive cruise control at 70mph+, the emergency braking will suddenly activate, even when the road ahead is completely clear with no surrounding traffic. The car will suddenly brake, sometimes dropping 30mph or more off of speed, from 75 close to 40. Stepping on the gas pedal will abort this braking. If left alone, the car will stop braking and accelerate back to the original speed with no driver input. This will happen multiple times over 40 miles of highway driving. If it happened when being closely followed, the chance of being rear ended by the trailing car is high, though thankfully this has not occurred yet. The problem happens daily on commuting and has happened since taking ownership of the car on Jun 29, 2022 through today.

Numerous times while on cruise control “autopilot” the car suddenly and rapidly decelerates for no apparent reason. Most often when no other cars or obstacles are seen and during full daylight (no rain or other complicating weather) but has also occurred at night. Typically while driving at highway speeds 65-80mph and the deceleration is rapid and significant (decreases by estimated 20 mph within 1 sec).

First time interstate with new vehicle. Within first 100 miles of using cruise control at 80 MPH vehicle would suddenly phantom brake. Occurred twice within 50 mile span. Stopped using cruise, as we were almost rear ended. Attempted later in trip with no trailing vehicles; phantom braking occurred within 50 miles of using. Stopped using due to major safety concerns.

While using cruise control, for no apparent reason, the car rapidly slowed as if the brakes had been applied. This occurred multiple times before I stopped trying to use cruise control.

The contact owns a 2022 Tesla Model 3. The contact stated while driving 75 MPH with cruise control activated, the vehicle experienced phantom braking. The contact also stated there were no vehicles nearby. There were no warning lights illuminated. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 3,000.

Multiple Phantom braking events with hard deceleration which nearly caused the car behind me to rear end my vehicle. Car suddenly braked and speed Was reduced from 72 mph to 55 mph before I could disengage the autopilot. At the time nearest vehicle In front of me was a over 1/2 mile away. Was traveling West bound around 0800 issue was severe enough that I did not trust reactivating the system until I reached my destination and could put the car in park. This was the second such episode in phantom braking in less than a week. The episode last week occurred as I was approaching a bridge and I am guessing the car mistook the shadow across the road as a vehicle

Driving on a 2 lane highway on July 15, 2022, using Cruise Control. A tractor trailer was approaching me. The truck did not cross the center line. There was no concern of a potential problem. With no warning, The Tesla applied extremely hard braking. I had no idea for the reason, afterwards I thought that the motors failed & ceased. If the right brake did not grip as much as the left, the car would have been steered into the other lane into the path of the truck, death would most likely have resulted. The car also braked for side roads, not as intensely as when the truck was approaching. A Tesla rep was notified with a request for immediate repair. The Tesla Rep downplayed / minimized the issue and stated that the issue could be resolved in an update (with no time frame). I am in fear of using Cruise Control on 2 Lane roads.

The Auto-Pilot system, Tesla's version of adaptive cruise control, 'phantom' brakes with no obstruction in the road. It has happened to me many times on a recent long trip. perhaps a dozen times over 1300 miles. It has occurred when I am on the only car on a quiet country road and on busy highways. There appear to be 2 types of braking; one in which the brakes are actually engaged and the other in which is appears that Auto-Pilot just turns off and the system allows the regenerative braking to slow the car. At times it happens over slight dips or undulations in the road. On another occasion it happened when the car 'sees' a sharp shadow under an upcoming bridge in bright sunlight. Most of the time when approaching a bridge It does not phantom brake. However it did do this when approaching two consecutive bridges under identical lighting conditions. This all may be a function of using a camera based system for cruise control. I am making this report because I was to go on record in pointing out it is a very very big problem. I wish I had more real data to share with you. Tesla needs to cooperate with you to fix this immediately. It is a serious safety issue. Thank you.

A day of Phantom Braking today while the car was on adaptive cruise: -Going on the interstate up a hill, and on the crest it freaks out and slams on the brake -Going on MN Hwy 18 at 6:30 pm north, and dozens of phantom braking incidents in shadows, dark colored patches of road, and for random reasons. Got so bad I stopped using the feature

Car is phantom breaking with cruise control set on the freeway.

The Autopilot feature regularly doing hard brake without good reason, and often happens without any warning. This is dangerous for everyone on the road and major liability hazard for the car owner.

I bought my car new from Tesla in March of 2022. I drove it off their lot in Minneapolis and was my way home back to Bismarck, ND. Within 10 miles of being on I-94 with basic cruise control on, the car suddenly and unexpectedly slammed on the brakes. I had the cruise set at 80 mph and the stop was so sudden that I went down to around 45 mph within a second or so. It happened a few more times within the next 20 miles or so, so I called the service number. The lady on the service team told me that I just needed to "recalibrate my cameras". So I pulled over and did what she said all to no avail. It continued so I just did not use cruise control. Over the next few months, every single time I would go on a highway and use basic cruise control - I would get the same thing and experience extremely dangerous "phantom braking". And each time I would call Tesla service and they would remote dial into my car and tell me the same thing: there is nothing we can see and nothing appears to be wrong. Essentially saying I'm imaging this all happening. At the end of June or beginning of July, I spoke with a Tier 2 tech and he asked me to be very specific if I could and next time it happens to log exactly when, where I was, etc. this happens next. On my way back from Denver it happened so frequently that I again turned off the cruise - but I did what he mentioned and I documented the exact times and whereabouts as requested. I submitted that info a few days ago - they just responded last evening saying again that nothing is wrong and "it is the drivers responsibility to stay aware and alert at all times". So I responded by saying nothing of this was ever disclosed as a known risk to me before I bought the car and the fact that you are now claiming that essentially nothing is wrong, you are therefore suggesting that this phantom braking is not a real issue. The concern with this answer is their apparent refusal acknowledgment suggests no fix is coming.

I have experienced multiple instances of what I see others seem to be referring to as Phantom Braking. The car will decelerate from 70 mph to 40 mph in seconds with absolutely no other vehicles, obstacles, etc. in sight. Typically the issue happens on 2 lane divided highways )2 lanes in each direction separated by a natural median) during the day time. Without any warning the car will rapidly decelerate using the brakes so aggressively the anti-lock brakes are being engaged as you can hear the tires skidding/squealing. The braking is so aggressive everything loose in the car flies forward including occupants. My typical reaction is to press down on the accelerator immediately to get back up to speed in case there is someone behind me. I picked up the car in March 2022 and experienced the issue in the first couple days. While a Tesla tech was at my house installing the Home Link system I inquired about the issue to which he responded its a known issue with no known resolution. I have continued to drive the car and at times need to turn off any speed control as I have dealt with multiple incidents in just a couple miles. The common item I have seen is when there is a glare/glimmer/mirage on the payment ahead. I took it in for service yesterday and they stated unless they can reproduce it, nothing can be done. I gave them the time and date of an event, they said they would pull the logs, yet nothing was done. They put a comment in the paperwork the system is only a BETA (see attached service document). This is a very serious issue which is likely going to cause a serious accident resulting in injury and/or death. I cannot even think what would happen if the roads are wet during a situation like this. The arrogance of the Tesla service team was unbelievable.

We have not yet had an accident but have come close due to phantom breaking when using the cruise control with our Tesla. We have reported the concern to Tesla as of 7/21/22 and were told to reset the computer but they have not been able to offer any other solutions. We are very concerned for our safety as we cannot reliability use our cruise control.

When driving at highway speeds on open roads with light traffic with the adaptive cruise control ON the car would severely brake at random. I have seen this referred to a "Phantom Braking" in other reports. This happens several times an hour and the brakes are severely applied automatically, reducing the speed from 70-80mph to 40-50mph before I can intervene by stepping on the accelerator pedal. It is a frightening experience and can throw the driver and passengers up against the seat belts. This is a critical safety issue because it can result in a rear end accident if a car is following too closely. I have not taken the vehicle for inspection yet but I see there are many reports of this same problem on social media and the NTSB has already opened an investigation on this problem. The vehicle is only a few weeks old and it became noticeable during a long distance open road trip through the open highways in Utah, Idaho and Nevada.

Adaptive cruise control kept abruptly decelerating and/or braking whenever a car passed in the opposite direction on a two lane highway. It also sometimes did the same thing when going over a rolling hill. As the feature exists now, it is completely unusable on certain roads. There is a risk of a rear end collision if the car brakes for no reason when using adaptive cruise control. At the very least, there should be an option to disable the adaptive feature of cruise control when the system is unable to work properly.

Phantom braking at highway speed nearly caused an accident. Happened several times over a 400 mile trip. Tesla's "Navigate on Autopilot" feature apparently confused other vehicles on the highway for hazards, and slammed on brakes, creating a collision risk for cars behind me. It also happened when the painted line on a highway ended and the road split. The car may have confused this for the road ending altogether, and it slammed on brakes while I was going at 65 mph. This is a new car (3 weeks old).

While using Tesla adaptive cruise control on the Ohio Turnpike on a sunny day, the brakes engaged , causing the vehicle to slow quickly. There were no obvious obstructions, other vehicles, road conditions, or formations that should have caused the system to brake. There was a large green and white reflective road sign along the right side of the road. I was able to press the accelerator and return to speed. If I hadn't been able to return the car to speed quickly, a large truck behind me would have had to brake hard to avoid a collision.

I'm looking for an update to the reported Tesla "phantom braking" issue when on Autopilot. We experienced this at least 5 times during an April 2022 road trip from SLC to Vegas, so bad we didn't feel comfortable enabling Autopilot (cruise control) on the drive home to SLC. This made for a very difficult 6 hour drive as Tesla's are very hard to keep a consistent speeding since they are so quiet/powerful...w/out some sort of auto speed regulation. I didn't know where to report this and was simply waiting for an over-the-air update for this to be addressed by Tesla and have seen none and no follow up news reports. I'm assuming this must be affecting 100's of thousands of Tesla owners.

Under Adaptive cruise control, the car slowed from 80mph to 55mph on the highway. There were no cars or objects in front of us. We tried to hit the "gas" pedal but the car would not let us override it. The car behind us came extremely close to us and flashed his lights at us. Bug report submitted to tesla. We were traveling downhill with a slight right curve.

Since purchasing this vehicle new, I have experienced no less than 40 different incidents of Phantom Braking where, while using Tesla's adaptive cruise control (and ONLY adaptive cruise control), my car has suddenly and violently applied the brakes while traveling at highway speeds (between 65-75 mph) on interstate highways where there were no obstructions or other vehicles that posed any risk. I have extensive experience driving other (non-Tesla) vehicles with adaptive cruise control, so I understand some of the potential limits regarding when radar/cameras might mistake an obstruction or a gap in observations for something that would require braking, but that is not what is happening with my current Tesla. Instead, on wide-open interstates, with no other cars for hundreds of yards around me, the vehicle with suddenly violently apply brakes, forcing me to have to take protective and corrective actions to avoid swerving or becoming a hazard to other vehicles, all of which are also driving at highway speeds. I have NOT had a crash due to this, but the sudden braking and deceleration has forced other cars around me to have to suddenly brake and swerve.This has happened about 10 times on EACH of the following dates, each of which was a one-day leg of a drive anywhere from 500-800 miles: (5/26/2022, 5/30/2022, 7/1/2022, and 7/5/2022). I am just going to add one of these dates below, but I am happy to be contacted to provide more details.

Hello, I purchased a Tesla Model 3 in March 2022. The car will randomly brake while on cruise control and the auto pilot on the highway , there is nothing on the road in front of me when this happens. I am very concerned that I may get into a car accident or cause others behind me to brake abruptly in response to my car resulting in potent accidents.I feel this is quite unsafe. The phantom breaking has happened multiple times. I am driving from Texas to NC where the cruise control is crucial but am worried about the braking problems. I have not had the opportunity to take it to the dealer yet about this problem. It’s unknown to me if the manufacturer inspected this component. There were no warning signs of any type prior to the phantom braking happen. Any insight or guidance you can provide would be appreciated. I appreciate you taking the time to read this. What component or system failed or malfunctioned, and is it available for inspection upon request? Autopilot navigation and cruise control, yes it is available for inspection upon request How was your safety or the safety of others put at risk? Vehicles behind have to brake every time the phantom breaking happens putting everyone at unnecessary risk to avoid a crash. Again, there is no need for the sudden breaking when it occurs. Has the problem been reproduced or confirmed by a dealer or independent service center? No. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No.

"Phantom braking" occurred on multiple (30 or more) occasions while the adaptive cruise control was engaged. These phantom events happened during a long road trip across west Texas. These events seemed to occur whenever there were few or no cars visible in front of my vehicle and as I was cresting over small rises in the highway, meaning the brakes would engage just after the car reached the high point and started to descend slightly, perhaps because the cameras briefly lost visibility of the road and could not register any oncoming traffic. ALL of these events happened during daylight hours and, on more than one occasion, there were drivers traveling behind my car. Also, there is no way to engage the cruise control without also engaging the "adaptive" feature that uses the cameras to brake in case of emergency. This is a very dangerous flaw in the technology. It causes the passengers within the car to be lunged forward unexpectedly and is very unpredictable for drivers who are traveling behind the car. These phantom braking events most often occurred when the road was completely clear and visibility was at or close to 100%. Tesla needs to do better.

"Phantom braking" occurred on multiple (30 or more) occasions while the adaptive cruise control was engaged. These phantom events happened during a long road trip across west Texas. These events seemed to occur whenever there were few or no cars visible in front of my vehicle and as I was cresting over small rises in the highway, meaning the brakes would engage just after the car reached the high point and started to descend slightly, perhaps because the cameras briefly lost visibility of the road and could not register any oncoming traffic.

The autopilot feature suddenly braked without any alerts (visual or audio.) This happened multiple times (about 10-15) on a two thousand mile road trip. The phantom braking occurred only at high speeds on expressways. It seemed to occur more frequently when driving up a hill. It may also have been triggered by shadows. It created a dangerous driving environment in that the speed decreased drastically without warning for the Driver as well as other drivers on the road.

While driving on a highway with adaptive cruise control set and no visible vehicles or obstacles on the roadway, the vehicle slammed on the brakes and slowed to about 2/3 the speed. I disengaged the cruise and took over and was able to then speed back up. My concern is that had someone been close behind me they would have for sure ran into me! At highway speeds this could seriously injure or kill someone. This happened 2 times on July 10th, on my 360 mile trip and also happened on the way to this location 1 time but was a quick brake incident only slowing 10 mph and then went back to the speed I had set…that was the first time and that date was July 7th.

my brand new tesla model 3's adaptive cruise control is unsafe and unusable while driving on a two lane highway, I took a 500 mile road trip last night and the entire time i was experiencing random hard breaking while driving. I have stopped using it since but it has me worried about my safety as well as other when using this program. I am also having issues with my lane keep assist activating despite it being fully disabled in settings, it pulls my steering wheel back into the lane when i am changing lanes, even with a turn singal, and the computer system screams like crazy telling me im departing my lane. This almost caused me to crash one time as I had to overcome the computer pulling me back into the lane I was already in, despite me intending to change lanes.

On several occasions while my Model 3 was under cruise control the vehicle brakes for no reason. From 65 mph to 25 mph in moderate to heavy traffic nearly causing a rear end collision each time.

Driving 1-25 south in clear and sunny weather at posted speed limit, clear road in front of us, automatic brakes engages for no reason. Car behind us had to take evasive maneuver to avoid collision.

TESLA "auto pilot" (adaptive cruise control) has activated breaking, with no object in front. Last event was 7/9/2022 on the highway going about 77 miles. Because the break are activated unexpectedly I almost lost control of the vehicle, and the vehicle behind me almost collided with us. I this time I have discontinued using the autopilot. Using the autopilot on this vehicle is extremely dangerous. Please help

Just completed road-trip from Florida to New England and back. Experienced 4/5 phantom braking events while using cruise control at highway speeds. When traveling in traffic at highway speed, this abrupt braking came very close to causing a collision.

While driving 2022 Tesla Model 3 with cruise control, the car phantom braked with nothing around vehicle. This happened approximately 20-30 times while driving for about 8 hours. The phantom braking occurred while cruise control was set a 75 mph and and went to around 65 mph. This has occurred at varying speeds. It also occurred while using the auto-pilot feature. This happened the next day numerous times. It also braked on a two lane highway after a vehicle passed our car. There was no warning or indicators before, during or after. I am really concerned that this will occur with a vehicle behind my car and cause a rear end collision. Need to see Tesla dealership when return from current trip. Any help would be greatly appreciated.

While driving on the interstate and having the adaptive cruise control enabled, the vehicle unexpectedly and suddenly decelerated with no vehicles in front of us. This happened 3 times over a two day period, with a total time of about 3 hours having the cruise control on. The 3rd time it happened, we were traveling at about 75 mph with another vehicle behind us, no more than two seconds behind. No vehicle was in front of us, but our car suddenly decelerated by about 20 mph. If the driver behind us was not paying attention, they would’ve rear ended us. I sent in a service request to Tesla. The answer was, in summary, they are aware of this issue with their beta version of adaptive cruise control and are working on a firmware update to fix it. The solution given, in the meantime, is to disengage the cruise control when it happens. This is unacceptable to me, as the consequences of sudden, unexpected deceleration will have already happened. I am not going to use the cruise control until it is fixed. For such an expensive car, still under warranty, an unusable and dangerous feature should be fixed.

Phantom breaking system continuously is stopping out of no where. Happens when vehicle is on autopilot and also happens when vehicle is on cruise control. It slams the brakes and lowers speed approximately 20 MPH’s in a matter of a second. Seriously increasing the chance of being rear ended. It’s enough braking power to send you forward in your seat. On my current trip driving through Nevada to Idaho it happened approximately 5 times within 20 miles before I gave up and turned it off. I have also experienced problems before where the car merges lanes on the freeway but does not take into consideration the car in the lane that it’s merging into. Accident waiting to happen.

I was driving in our new 2022 Tesla doing 55 mph using the adaptive cruise control, not on auto pilot. We were on a divided highway, a few cars coming from the opposite lane, nothing in front of us when without warning the car heavily braked. It frightened us and I pressed the accelerator and the car continued without any further incident, but the episode was scary because earlier in the day we were driving on a heavily traveled interstate where such an episode could easily have caused a collision

Driving on I8 between San Diego and Phoenix with no obstacles or vehicles around with cruise control on, vehicle was brake hard for no apparent reason. This happened multiple times. Disabled it as we were concerned we would get rear ended.

Recently, while traveling on the freeway with light traffic conditions (no cars near me to the front, sides or rear -- possibly no cars even visible) the car automatically applied the brakes causing the speed to drop by more than 30 miles an hour. This happened three times over the course of two minutes, with one of the incidences being particularly severe (throwing me forward in my seat as the brakes were applied). Had a car been behind me, I'm sure I would have been rear-ended. At the time, the weather was clear, and the time was near noon, putting the sun nearly overhead. I did not detect any shadows or unusual road patterns at the time of the incidences, nor was I near any overpasses. At the time of the incidents, the car had its "traffic aware" cruise control engaged with the lane following feature active. Later that same day I experienced a similar incident with heavy, unexpected braking (same freeway, now heading in the opposite direction, about one hour from sunset), with traffic aware cruise control engaged but without lane following engaged. I have experienced milder versions of unnecessary automatic braking about 6 times. They were annoying, but not a safety issue. In at least one of the incidences described above, the braking was so severe, I do think it could have gotten me killed if a vehicle had been close behind me. I'm now afraid to use the feature in moderate traffic, which is a shame, because it is in under exactly that circumstance that the feature is most useful.

I engaged cruise control on my 2022 Tesla model 3 at 70 mph while traveling on flat level terrain, and after about 1 to 2 miles in cruise, braking automatically occurred slowing my speed down to 50 mph in less than 2 seconds. I've read that this is considered phantom braking which is considered common on the newer 2022 Tesla model 3. There were no warning signals and no visible objects on the road, and the time of day was about 4:30 pm. I took the vehicle to the dealership for another issue, but they didn't have time to take it for a test drive. I was thrown forward in my seat when the incident occurred, and fortunately there were no other drivers immediately behind me.

While the car is in Auto Cruise control, especially in the 72 mph and above range, the brakes engage for no reason. This happens repeatedly on long travel days. There is no notice of the slowdown. It can be abruptly and be extreme. The accelerator has to be used to disengaged the braking. We see it called phantom braking. It certainly is not safe.

When driving using cruise control on highway, car suddenly applied brakes with no other vehicles or obstructions present ahead or beside us. Car went from 80mph to 60mph. Had there been a car behind us, there may have been a rear-end accident

Numerous times, my Tesla Model 3 has randomly slammed on the brakes or rapidly reduced its speed while on Autopilot. This has happened several times even when driving on flat level ground and no vehicles around me nor was there any debris in the road. It has also happened numerous times within several minutes while on the same flat road. The car also has a tendency to brake or turn off Autopilot when coming up to a hill that it seems to interpret as a car or object in the road. This can be very jolting and scary and if you aren’t ready on the accelerator pedal to speed back up there is a very real chance to get rear-ended.

While driving on a two lane road, I was utilizing Tesla Autopilot to maintain speed and keep the vehicle centered in the lane at 60mph when the vehicle slammed on the brakes for no apparent reason. No error messages, beeps or chimes went off to indicate to me why it was slowing down very quickly. I have had this happen several times in my first 3 months of owning this vehicle and there have been times that the car has slammed on the brakes when another vehicle was following closely which could have resulted in me getting rear-ended. Tesla Autopilot can be extremely helpful, but at the same time it is not reliable and may result in an accident at some point.

The contact owns a 2022 Tesla Model 3. The contact stated while driving at high speeds with the cruise control engaged, the Forward Collision-Avoidance Automatic Emergency Braking System engaged without warning. The local dealer was not notified. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and the contact was referred to the dealer for assistance. The failure mileage was approximately 1,000.

I was on auto pilot and cruising at 75 mph and car breaks automatically without any car in front of it(Phantom Breaking)

Taking two 300+ mile trips, last Friday (June 24)and yesterday Monday (June 27), while on Auto Pilot with the cruise at either 80 or 85, the car had multiple phantom braking issues. The car would decelerate between 10-20 miles instantly with no obstacles or other cars around. This happened at least 10 times total with both trips. So much so that I have no confidence in using this feature again. It's horrifying when it happens.

We are on a trip from California to Indiana and have had 9 instances so far of the car suddenly stopping while the cruise control is on. The last incident we are doing 75 mph and car stopped suddenly and car following us almost hit us and driver was pissed to the extent of road rage. This needs to be addressed!!

Phantom braking at interstate speeds when vehicle was in autosteer. On a recent 600+ mile day trip I experienced 5 separate instances of instant phantom braking when the car was travelling between 70 and 75mph with autosteer on. The car would brake violently from 70mph to around 50mph in milliseconds without any observable obstacles and no visual or audible warnings from the car. The driver notification log does not show any instance of the event.

At least 6 times on a trip today the traffic aware cruise control cut out and slowed the vehicle dramatically for absolutely no reason. If there was a vehicle close behind me, there would likely have been a collision. The weather was clear with no vehicles remotely close to me. About 1/2 the incidents were on a two lane road in the California desert. Other dramatic events were on interstate highway when my vehicle had just passed an off-ramp, I was in the right hand lane. Tesla has been notified via a bug report each time it happened. Tesla is aware of the problem and says we don't need to take the vehicle to a service center.

My car continues to slam on the brakes completely at random while using cruise control. This is unsafe because it could easily cause a collision from the vehicle behind me. It also causes road rage because people think I am brake-checking them. Someone waved a gun at me after my car braked randomly in front of them on interstate 10 in Phoenix. Tesla service center says this is currently normal behavior for Teslas without radar and nothing can be done. They offered troubleshooting options which I tried, but there has been no change. My car has no warning lights present.

I was driving on the Interstate in Montana I-90 at 75 MPH using the adaptive cruise control when suddenly the car began full braking nearly resulting in my loss of control of the vehicle. I noticed no warning sounds or lights. Fortunately, there was no one immediately behind me or the car would have been rear-ended. It happened when the road was curving to the left and there was a tractor-trailer parked in the right breakdown lane. I suspect the car’s adaptive program assumed the parked truck was stopped on the road in front of me and applied the brakes.

I’ve only had my car for 2 days and have had 6-7 phantom braking issues. First day I was driving home from KC, MO after picking up my new car. 4 random stops with the brakes. Some as we approach a (under) bridge, some the top of a hill. Is it falsely detecting radiant heat as an object? Second day same thing, but on new software update (6-25-22). Shorter trip, so fewer incidents. I recall one where no cars were in from of us and there was some asphalt patches on concrete highway. This triggered emergency brakes again.

while driving from Arlington, VA to Haymarket, VA on Interstate 66, i was using Tesla Autopilot (adaptive cruise control) and experienced several instances of sudden braking for no obvious reason. Depending on the location, the car braked suddenly, without any warning, from 65 MPH to 42 MPH, again from 65 to 45, 65 to 38, and 65 to 49. In each case, I was driving in the right lane (of 4 lanes). In these cases, the cars in front of me were a long distance away, perhaps a quarter of a mile. There were no cars in the lane adjacent to me. The braking was sudden and severe, dropping form 65 to 42 in one second. This was both scary and dangerous. Twice there was a car behind me, following at a safe distance that had to swerve out of the right lane to avoid an accident. During this same drive, there were 2 other instances of braking that appeared to be correct: once while driving under an overpass and once in an area of construction where the extreme right part of my lane has a raised section that caused the car to tilt significantly. These 2 instances were what I would have expected.

Cruise control was set to 70 mph on main turnpike. Shortly thereafter the car slammed on the brakes without any traffic around bringing the car almost instantly down to 45 mph. Had to override brakes by stepping on accelerator.

When driving down a 2 lane, desert highway in California at about 60 mph, the cruise control cut out for no reason. There were no vehicles near me. This happened 3 or 4 times within an hour of driving time. When the cruise control cuts out and/or emergency braking occurs, my vehicle slows dramatically. There is a significant risk of a collision if there was a vehicle behind me due to my sudden, and unnecessary dramatic change in speed. Tesla has been notified via a bug report. Tesla says this is a known condition and may occur. I feel this is a safety issue and must be solved or have the traffic aware cruise control changed to a standard cruise control that requires driver action to be disengaged.

While backing out of my garage the car accelerated uncontrollably and climbed the curb of my driveway. I tried braking without any success. A message saying, to the best of my recollection, "Automatic Braking Disabled" appeared on the dashboard. After climbing the curb the vehicle came to a stop and "Hazard Lights" came on. There were less than 50 miles on the odometer at this time. After waiting for a few minutes I gently pulled the car off the curb and slowly drove it back into the garage. I discovered broken lug nut and what appeared to be its casing lying in the driveway. Tesla Service Center sent tow-truck to tow the vehicle away to its service center. I handed over the broken lug nut and and its casing to the Tesla Tow-Truck Person. While towing my car suffered even more damage as the passenger side front wheel became almost horizontal and it considerably damaged the front bumper. The photos of all these are uploaded with this incident report.

Three times in 15 minutes during my road trip, while driving in autopilot my car braked for no reason with no obstruction. Fortunately, no one was hurt or injured but it could have caused major issues if there was more traffic.

In good weather, ample light, and with empty road ahead my new Tesla has braked hard while the adaptive cruise control (auto pilot) was on. This has happened on 3 lane highway and two lane (one lane each direction) roads 3+ times over the 750 miles I’ve put on the car.

Phantom braking when cruise control activated and truck approaches on two-lane roads. Braking can be so hard that it can be dangerous and unanticipated. It happened virtually every time a truck (e.g., log truck, 18 wheeler) approached as I drove on Highway 99E from Corvallis to Monroe, OR on 22 June 2022. My remedies: Turn off cruise control, definitely keep hands on the wheel, and remain very aware.

The contact owns a 2022 Tesla Model 3. The contact stated while driving approximately 80 MPH with the cruise control activated, the vehicle started to quickly decelerate independently. The vehicle slowed to approximately 60 MPH. The contact stated no warning light was illuminated. The vehicle then slowly returned to the cruising speed of 80 MPH. The contact stated that the independent braking became a recurring failure. The contact stated that the independent braking also occurred while the vehicle lane departure control was activated. The contact had not taken the vehicle to a local dealer. The vehicle had not been diagnosed or repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 5,000.

Mileage: 5,000

Sudden and unexpected deceleration while using cruise control or autopilot. E.G. - cruise control set at 65mi/hr then the car randomly applies the brakes and slows down to under 40mi/hr. It happens several times during a trip, every trip, when cruise control or autopilot is used.

This concerns the "Phantom Braking" problem occurring to many Tesla owners recently. I took delivery of my new Tesla model 3 on May 3, 2022. I was very cautious about enabling the advanced features of the car such as Autopilot, and I did not experience the Phantom Braking (PB) problems that some of my friends described with their Tesla. I bought the Full Self-Driving (FSD) package but I have not asked for it to be enabled. Then I left my house on June 9th for a 12 day, 2500 mile round trip to Seattle and back. During the trip I cautiously began to use autopilot functions, and found them to be very useful, particularly the TACC cruise control feature. As the trip progressed, I began to use the TACC more and more because I was beginning to conclude it might be safer than my own driving in specific situations). On the 6th day I began to return home and increased my use of both autopilot functions (TACC and auto-steer). The further I drove, the more certain I became what was happening, but not why. But first you have to understand the constraints. TACC controls the accelerator and the brake pedal and therefore also controls the regenerative braking capability. The other half of autopilot is the auto-steering capability, which controls only the steering wheel. But the important part is -- you can operate the car with only TACC engaged but you can't engage auto-steer unless you activate TACC first, or at the same time. During my trip I experienced some degree of PB something like 25 times. The 3-5 worst were similar to stepping on the brake pedal firmly. On one occasion I had no traffic near me so I didn't immediately override the stop, to see what it would do. The car continued to rapidly brake from about 75 mph down to about 25 when I stepped on the accelerator to break the PB episode. My conclusions -- PB is a TACC problem. Auto-steer does not change the behavior and PB doesn't happen unless TACC is engaged.

On the freeway on 6.19.2022, while in auto pilot, car displayed an extreme case of phantom braking. Potentially could have caused an accident

Driving at 70 mph on interstate with little surrounding traffic. Twice within one hour while using TACC the car suddenly braked. Luckily no one was behind me. The first time there was an overpass in the distance. The second time may have been related to bright sunlight on the highway ahead that glared and looked like black ice from a distance. Tesla was notified and acknowledged that this could be scary, but the car was checked out as having no issues. They said you just have to be careful. There was no warning of either episode. The car is brand new and the two episodes occurred within the first few hours of using TACC.

My Tesla Model 3 was on cruise control (not autopilot) and braked suddenly. I was driving 75 MPH and the car braked to 50 MPH in a matter of one or two seconds. It was a perfectly clear day and there were no cars in front or behind me within a mile distance. There were no objects on the road and absolutely no reason to brake so suddenly. The vehicle was only in cruise control. Lane keep assist (autopilot) was not enabled. Again, there was absolutely no reason to brake. Had a car been behind me, it would have been very dangerous and could have caused an accident. The car braked on its own quick enough that someone behind may not have had time to brake. Cruise control stayed on throughout the entire incident. I turned off the cruise control and took manual control and was able to drive without any issues. This is a serious safety issue that needs to be addressed by Tesla. I feel unsafe using any of the ADAS systems. Also, the car has 1K miles on it and this has occurred three times. The other two times when it occurred the car was in autopilot. All three time the car was driving on the highway in Texas and Oklahoma.

While using traffic aware cruise control, either the cruise control cut out or emergency braking was initiated causing the vehicle to rapidly slow down. This happened once on a two-lane road and multiple times on a four-lane, divided highway. My vehicle slowed very rapidly from about 70 mph to about 50 mph. If another vehicle had been close behind me, they might have hit me due to the sudden, unexpected decrease in my speed. There was no hazard, vehicle or otherwise, in front of me at those times. Tesla has been notified through a software bug report. Tesla says this is a known possibility, but has not fixed the safety-related defect. This happened on highway 14 in the California desert well away from any town or city in daylight and in good weather.

While making a trip to Vegas with the family, I experienced 4 different phantom braking events. 1 was so bad that I almost was rear ended. I saw no common theme between all the events, but they all seemed to happen when there were no cars in front of me at all. All happened in a highway setting.

Vehicle suddenly braked randomly while using cruise control. This happened many times driving from Colorado Springs to Albuquerque on I25. No identifiable cause or roadside hazard. It would brake slow down in a dangerous rapid manner. Cars behind had to avoid hitting us. It became so bad I had to stop using cruise control for the majority of the trip. It is unsafe and scary.

The car has been phantom braking when in cruise control and auto pilot for no reason. This has happened multiple times where it throws the driver into the dash, and it brakes hard. This can cause an accident on the roadways and also the driver if throwing the driver into the dash. This has been going on since we have gotten the brand new car earlier this year. There have been multiple updates to the car but none of the updates have not resolved the issue.

Was traveling on auto-pilot on an uncrowded 2-lane highway, 1 lane in either direction, about 65-70 mph. Car suddenly braked quite drastically for no apparent reason except that perhaps there was a truck in the distance. However, the car had "seen" plenty of trucks before and after and didn't respond in this way. Note that this happened 3 times, possibly 4, on 2 separate days, and only on AUTOPILOT. Note also that the autopilot was functioning as a cruise control because I had 2 hands on the wheel and was not really allowing autopilot to steer. I stopped using autopilot after that.

Using Tesla Autopilot April 13 and April 15 on CA 395 between Los Angeles and Mammoth Lakes the car repeatedly had "phantom braking" incidents with no cars or obstacles in sight.

Phantom Braking. Both in Cruise Control and Auto Pilot (I do not have self driving). The car brakes suddenly for no apparent reason. Often it is to a full complete stop very quickly, occasionally it is a half stop. I have documented occurrences, honked so that the vehicle has a computer recording and I have taken it to the dealership in Las Vegas Nevada where I purchased it. They worked on it for several hours (2/7/22) and said it is nothing physical, must be a computer issue, they will let me know when they have a fix for it. They gave me a number to text to see if there are updates. I texted regularly, only got one response, and it said "that's the way the car is designed to work". No. It feels like it is only a matter of time before someone rear ends me. So no using cruise control, which I paid for and they won't fix. It has happens since the day we brought it home, and at all speeds

While driving at approx 80 MPH along a major highway at approximately 11:30 PM, and while utilizing cruise control, my Tesla Model 3 applied brakes when no vehicle or object was around. My hands were on the wheel and I was focused on driving but the force of the braking caused passengers to move abruptly forward in their seat belts and startled me as the driver. The speed abruptly went from approx 80 down to below 60 MpH. This has happened multiple times. I contacted Tesla support and was told that this is a known issue called “phantom braking.” Since I have NOT used this feature and was told that there is currently not a fix or estimated software release.

Driving on freeway, very little traffic, no cars near me. Speed 73 mph. Sudden loss of power, coasting to stop making a lane change and seeking shoulder space. At about 30 mph power was regained. Sudden loss of power. ( electric motor, motor controller, battery or software failure ) Difficult rapid maneuver to get to side of road. Dealer has made an appointment. Nor warning lamps or warning sounds. There was another incident 2 days earlier when the cruise control would not engage. Two trips no cruise control. yellow warning symbol with "Cruise control unavailable" Made an appointment with Tesla, they cancelled saying that the car did not do that, and my appointment cancelled. Tesla or vehicle software lies.

Two separate times today the car automatically braked hard when there was nothing in front, nor around us, when we were using cruise control.

I purchased and received my Tesla Model 3 earlier this year. On 6 occasions, while using Cruise Control, the car automatically and unexpectedly braked when there was not a car within a 100 meters in front of me in my car lane. The unnecessary and sudden automatic braking surprised the vehicles behind us which increased risk for a crash and also minor whiplash to the passengers in the car. The Tesla's incorrect breaking seemed to be tied to when the car mistakenly through there was a vehicle immediately in front of me. One example was when the Tesla automatically started breaking when the shadow of a big rig was in the same lane as me. To be clear, the big rig was in the lane to the right of me, but it's shadow was in my lane. Another example is when there was a darker spot on the road in front of me. Overall, this is a significant safety issue and must be fixed by Tesla. Thank you.

I reported "phantom braking" to Tesla that occurred approximately 12 times on a 637 trip on June 4, I requested a service and Tesla responded on June 10 that it "performed remote diagnostic routines to check for any faults ..and found no faults. ...Phantom braking is a known characteristic of current firmware that Tesla is aware of and actively working to improve." The service technician sent me the following additional message: "I understand your frustration at the situation, I've personally owned a model 3 that experienced phantom braking as well. Our technicians in service cannot improve your situation for you at this time, this is a software issue that our engineers are actively working on improving. We are waiting for software updates to help mitigate this issue. These will be automatically sent to your vehicle when they are available." I maintain that it is a defect that affects the safety of the car whenever cruise control is used and that this defect was not disclosed to me at the time of purchase nor subsequently except after I requested service. The car hits the brakes without warning at highway speeds of 70-80 mph, this cannot be safe yet Tesla's Service message reply is "If the vehicle begins applying the brakes when you do not wish you may simply press the accelerator pedal to override the vehicle." I cannot understand why Tesla hasn't disabled this feature and communicated the issue and risk to the owners of these cars until it fixes its software so the car doesn't brake unexpectedly at highway speeds while using autopilot or adaptive cruise control.

On more than a dozen occasions, our Tesla model 3 while using traffic aware cruise control dramatically slowed down when no vehicles were around. This was mostly on two lane roads in the California desert. Some of the incidents were on 4 lane divided highway with no other vehicles around. Since the car slows so dramatically when the cruise control cuts out it is a very serious hazard if a vehicle was behind me. I have reported the problem to Tesla with no resolution. All I would like to have done is to give me the option to have a standard (non-traffic aware) option for the cruise control.

My concern first started with the cruise control suddenly shuts off. My biggest concern when the cruise control suddenly shut off and braked. When this happened we were traveling on Interstate 80. 4 lane highway 2 lanes each direction. Cruise control set at 80 mph. Approaching an 18 wheel truck moved to the fast lane. Half way past the 18 wheel truck cruise control suddenly shuts off and the car brakes. Traffic was light so lucky I wasn't rear ended. Notified Tesla they sent me a over the air software update. Not satisfied made appointment to bring into their service department. Was told their system doesn't go back to the incident and it happens again file a bug report. Not feeling safe with a car suddenly brakes.

The contact owns a 2022 Tesla Model 3. The contact stated that the vehicle experienced phantom braking while driving at various speeds with the cruise control activated. The contact had not taken the vehicle to the dealer. The vehicle had not been repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 4,235.

Mileage: 4,235

Driving like normal, using autopilot on the highway when I got an alert ‘Automatic Emergency Braking is disabled’, and the autopilot stopped working. Made a service appointment with tesla, but it’s scheduled for June 20, so thought this might help…

Vehicle brakes hard when there is no reason too do so while using traffic aware cruise control or Autopilot. Issue known as "phantom braking" to the general public. Brakes applied hard enough to lock tires and nearly lose control of the vehicle. Tesla needs to fix the issue and they need to implement a non aware cruise control option for when the system fails due to covered cameras or issues like this.

We were driving on I35 in Missouri traveling north and only had the adaptive cruise control on, and the car slowed down for no reason multiple times when no cars were in frown of us, or on either side of us. A few times, the car slowed from 70 to 60 or 65, but there was one occurence the car was attempting to slow all the way down to maybe full stop. We took control in each instance and avoided any further issues

The car unexpectedly brakes (without driver applying brakes) while in "traffic aware cruise control." This happens 2 to 5 times per 30 miles every time we drive the car on a highway, and has been happening regularly since we bought it about six months ago. Sometimes it's a brief stutter, but many other times it makes a hard brake, short of a full stop, but enough of a sudden deceleration that it poses a safety hazard for vehicles following the car. Sometimes the braking seems to be due to an oncoming large truck in the next lane, but other times it happens when there is no oncoming traffic. The braking is especially bad at night. We live in a rural area with only two-lane highways. The highways are not especially curvy. Sometimes it seems to brake for land formations such as distant mesas. Tesla service checked the vehicle's cameras remotely 2/2/22 but found nothing wrong. They recommended a reboot, which I did, but the problem continues to this day.

On 4 June 2022, at 5:03pm (CDT), while traveling northbound on Hwy 175 in Dallas, Texas and approximately 1-mile from the I-45 interchange I was traveling in the left lane with the Tesla Autopilot ON and speed set to 70 mph with a posted speed limit of 65 mph. There was very light traffic. When unexpectedly and suddenly the car began braking for no apparent reason. Since traffic was light I momentarily allowed the car to continue to brake arbitrarily in order to observe what it would do since I had also experienced this same phenomenon in our other Tesla that we own. The car continued its braking action unabated and within seconds had slowed to approximately 55mph and was continuing to brake on the highway for no apparent reason. Since traffic was now approaching me from behind at a high-rate of speed in order to avoid an accident I took over the accelerator and accelerated back to the appropriate highway speed.

On an interstate highway trip of approximately 200 miles, travelling at 70 mph with cruise control engaged, I encountered 5 episodes of phantom braking. With no obstacles or other vehicles in front of me, the car abruptly and without warning slowed down until I pressed the accelerator, at which time it resumed speed. In one instance I was being followed by a semi-trailer truck which had to change lanes as an avoidance maneuver. I should point out that there was one other episode of sudden braking, but this time there was in fact an obstacle, a large wheeled container of some kind, in my lane, which I was able to avoid. In this case I was very happy to have the emergency braking feature. I have not as yet found a way to report this directly to Tesla. They are notoriously difficult to communicate with. A brief online search reveals that this has been a common problem for some time which the NHTSA is currently investigating.

Over the course of 2 days on a road trip, the vehicle automatically engaged braking on its own 4 times. The first time was while using autopilot and traveling around 70 miles per hour. The brakes engaged so hard that the tires started to slights squeal before I was able to disengage. There were no cars behind us or we would most likely have caused an accident. Nearly the same thing happened then next day except I was using adaptive cruise control. This time there was a truck about 100 yards behind me that had been only a few car lengths behind me a bit earlier. If they were closer again, they most likely would have hit us. I know I was using cruise control one more that that happened, but I am not sure if I was using Cruise control or adaptive braking on the other time.

While driving at high speed on a freeway the car started braking without driver touching the brake pedal. Adaptive cruise control and lane departure were on. Fortunately no one was following close or it could have cause a serious accident. This happened twice on one day.

Phantom braking occurred multiple times while driving on hot days in the Desert. Traveling at around 70 mph, the car would apply the brakes hard and slow down until the driver takes over and disengages autopilot.

Was driving at highway speeds with adaptive cruise control on. The speed was set around 75mph. Came around a turn and was going downhill when all of a sudden the car slammed on the brakes to 55mph or less. My husband began to manually hit the gas pedal to bring the car back up to the proper speed but there was no response from the vehicle. The car all of a sudden corrected itself back to the proper highway speed. Luckily there was no one behind or in front of us.

My car while in auto pilot will sometimes randomly on highways at highway speed, slam on the brakes. It’s dangerous because you will be doing 75+ mph and the car will just slam on the brakes and you have to take over control quickly to keep up speed. It has happened to me on I-25 in Colorado and I worry sometimes that I could get rear ended. It doesn’t happen all the time just randomly.

Driving on interstate with autopilot on. I was cresting a bridge overpass when the car suddenly braked on its own even though no other cars or obstacles were in either lane.

When using Adaptive Cruise Control, my vehicle has experienced phantom breaking when cars are approaching from the opposite direction. It is so disconcerting, that I don't want to use the cruise control ever again. There is definitely a problem.

While driving on the highway and using the tesla version of cruise control, the car abruptly brakes with no obstacles in the area and the car is within the lane. The braking so abrupt that I think the car is about to cause an accident. This happens consistently in both the cruise control and the autosteer function engaged. Today I had the car set to 75mph with autosteer and no other car on the highway (4 lanes wide) and me traveling in the hov lane. Suddenly the car slowed to 65mph in less than a couple seconds before I was able to deactivate the cruise control. The feature is not stable and frightening to use.

When driving down the highway with autopilot active the car will randomly slam on the brakes. This seems to happen especially when going under or driving on overpasses with the autopilot feature enabled. When this happens the display indicates the max speed available for autopilot is 25 or sometimes 50mph which causes the car to slowdown rapidly from cruising speeds of 70-75mph. I understand there are limitations with the new vision only autopilot system but in these situations this rapid braking could cause someone to rear-end me or cause other drivers to think I'm brake checking them which could result in a road rage incident.

I have a 2022 Tesla Model 3, VIN # 5YJ3E1EBXNF115096, and anytime I use adaptive cruise control or auto pilot on a 2 lane road, I run into issues with phantom breaking. It also happens on 4 lane divided highways, but not as consistent. I’ve submitted “bug reports” via the voice commands every time it happens, but have not gotten a response. This is extremely dangerous as it can cause my car to be rear ended, or cause me to react incorrectly to the phantom breaking.

Multiple Phantom Braking incidences Nearly rear ended Have reported to Tesla on several occasions. First time reported Tesla replied back that the problem has be remotely solved. Not at all. Have experienced Phantom Braking many time since. Manufacturer has repeatedly replied with “our engineers are working on it”. No warning lamps, messages or other symptoms of the problem prior to the failure. Been happening for several months

What component or system failed or malfunctioned, and is it available for inspection upon request? Autopilot; yes. How was your safety or the safety of others put at risk? On several occasions while using "Autopilot", the vehicle attempted to come to a complete and sudden stop on the highway while driving at highway speed. On each occasion I've either had to quickly intervene by disabling "Autopilot" and accelerating or overriding the system by utilizing the accelerator pedal to keep moving then disabling "Autopilot" to avoid being rear-ended by the vehicles behind me. Has the problem been reproduced or confirmed by a dealer or independent service center? No. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No.

When using the cruise control or assisted cruise control, the car will brake suddenly and without warning as if there’s an obstacle in front of the car. In every case (more than 20 times) no obstacle is present yet it brakes regardless. In one recent case we were being closely followed and the trailing car had to suddenly maneuver around us into the oncoming lane. Thankfully there was no oncoming traffic. When I reached out to Tesla they acted like it was not common yet now I’m reading that it’s becoming extremely common.

We are on a cross country trip departed Rancho Mirage Ca on May 25th) for Hobart Indiana We have experienced phantom braking using cruise control at least 4-10x a day) On return trip while in ColorDo on I 86 June 1st @ 2pm the most serious and dangerous phantom braking occurred I had cruise control set att 75 ( speed limit) Road well marked, flat with no car ahead of us within a mile. The car had been experiencing phantom braking for last hour bringing speed down to 69-70 for no apparent reason A car was traveling immediately behind us when my Tesla suddenly braked to 58 mph. The car traveling behind us had to make a sudden and violent swerve around us, barely missing our car The other car quickly passed us as we stayed slow at 58 mph for a few seconds after the other car passed us This car needs to be recalled and use of cruise control suspended until recall remedies problem If this was my gasoline Escalade exhibiting such repeated cruise control malfunction , it would be taken off the road I am not new to owning a Tesla. This is our 3rd Tesla but we never had this problem with our Tesla S and only a few times with our X. This issue is a major safety problem and I am notifying media and newspapers of this problem, to ensure the NTSB addresses this serious problem. All data should be in cars computer system for verification

Frequent incidents of phantom braking when autopilot is engaged at highway speeds. Usually occurs on 2 lane roads, but has also happened on divided highway as well.

The vehicle while in adaptive cruise control or autopilot will brake hard at high speeds on wide open highway. It has always done this from day one but while on a Kansas open highway it almost caused a major accident 3 times in a short period of time. After the third incident I discontinued any driver assistance. The speed limit was 75mph, the autopilot was set at 75mph, in under 2 seconds we were at 35mph for no reason 3 times in row. I contacted Tesla after a few days after purchase and they said they know about it and it will get fixed in the future but its been 4 months. I had my 4 year old in the car and this is a very concerning issue.

Driving at 80 mph down divided highway, with emergency braking disabled on system and using only adaptive cruise control, when car slams on brakes so hard speed goes from 80 mph to 65 mph, causing the tires to screech from breaking so hard, and nothing in the road ahead of me, and nothing on the sides of the road.

When in cruise control and no obstacles in site, about every 10 minutes the brakes come on in varying degrees, sometimes a very hard brake. Once a vehicle was behind me and it nearly ran into me. It does not happen when anything is in front of me, such as following behind another vehicle, which I found I need to do to stop this from happening.

Vehicle brakes randomly when in autopilot or cruise control. It happens at least every 15 miles. There seems to be no cause or current emergency which would cause this to happen. Vehicle brakes hard, which is dangerous to myself and all traffic behind me. Was reported to manufacturer as a warranty item. Was told that this is not a defect or broken component, and could not be fixed.

In the past month, I've experience at least four sudden breaking experiences: 1. About a month ago I experience a sudden dramatic deceleration on Interstate 70 driving 67 mph. No vehicles in close proximity. 2. 5/8/22 on Hwy 7 driving 65 mph when car suddenly hard breaked. There were no vehicles near by. 3. A few miles later a red car driving 75-80 mph, at least, pasted me and as as soon as the car was ahead of me, the Tesla breaked. This was not as hard as (2) 4. A few minutes later a white car passed much like (3) above. Again a sudden break as (3) Other info: Mid nineties, bright sun, strong headwind and dry pavement.

Driving down Highway 54, a divided highway in southern New Mexico with adaptive cruise control set at 85 miles an hour, speed limit 75, with automatic emergency braking disabled, my car slammed on the brakes so hard, that the tires were screeching, with multiple vehicles traveling similar speeds to me approaching from behind. I had to press the gas pedal immediately to resume speed. When I looked at my speedometer, it showed a decrease in speed instantly of approximately 7 to 10 mph. While using adaptive cruise control, this frequently happens, despite automatic emergency braking being disabled. There was nothing in the road ahead of me to cause this breaking to occur, to include no animals, no humans, no items in the road, no other vehicles in front of me For at least half a mile in front of me, And the other car was not even in my lane, and not crossing the center markings. I have made a report through my in car system, however Tesla refuses to address the situation at this time directly with my vehicle. I called to schedule an appointment so they could download the data from my car to see what happened in the event, and they refused to provide service, nor an explanation.

I was using Tesla's Traffic Aware Cruise Control. I was traveling at approximately 75mph on a highway. There was a car approximately 6 car lengths ahead of me traveling at approximately the same speed. There may have been cars next to me on both sides. For no apparent reason, the Tesla braked and the speed was reduced from 75mph to approximately 35mph. I disengaged the Traffic Aware Cruise Control and accelerated back to approximately 70mph. My safety was put at risk because the car behind me had to slam on their brakes and I assume the car behind them had to do the same. This was dangerous for my safety and the safety of the people in the car(s) behind me. The vehicle has not been inspected. There were no warning lamps, messages or other symptoms prior to the issue.

I experienced phantom braking on multiple occasions when using either the cruise control or the autopilot. I experience various levels of braking force, and am unable to discern any pattern. The vehicle exhibits this unexpected braking most days that I engage those functions. Yesterday, on an approximately 350 mile cross country trip, the vehicle phantom braked on probably 10 different occasions. Two of those were what I would consider maximum braking effort. If another vehicle was following closely at those times it is very likely I may have been rear ended.

While driving on the highway with standard autopilot engaged and speed set, multiple times the car would apply brakes suddenly without warning. This typically would happen while cresting a hill. This is dangerous and could cause an accident if cars are following too closely behind. Also with standard autopilot engaged and while in the rightmost lane on the highway any time a road merged on the right side of the vehicle it thinks the lane got wider and will swerve to the right then left to try and maintain the center of the lane. This unnecessary turning could cause an accident or confuse other nearby drivers. During both of these events no warnings are displayed or heard in the vehicle. Both these issues are well known and discussed on Facebook, reddit and teslamotorclub forums.

I also shared this on Reddit: https://www.reddit.com/r/TeslaLounge/comments/ubcbuc/phantom_brake_occurence/ My brand new, (February-2022), Model 3 Performance Phantom Braked hard yesterday and almost killed me and my daughter. We were on a road-trip driving from Arizona to California, on the 8 freeway westbound. It was running Tesla software version. 2022.12.3.1. Conditions were ideal. Clear sky, open road, no opposing traffic since the opposing lanes were across about 200 feet of desert. No cars in front of us for any visible distance, road was straight for miles, no shadows, no reflections, just open road. I had the cruise control on and locked at 75 MPH. I wasn't using Auto Pilot, just cruise control, (single press down on the drive stalk). After cruise control had been on for a few minutes suddenly, the car hard braked, throwing myself and my kid forward. Decelerated from 75 to 30 MPH in about 2 seconds. Scared the shit out of both of us. We were just sorting out the confusion when we hear honking horns, cars would be on us soon. I slammed the accelerator to move. I later checked the outside of the car wondering if maybe a camera had become obstructed but nope, all the cameras had perfectly clean surfaces. This phantom braking issue is going to kill someone.

I have taken 3 road trips in my car since taking ownership, and on every single one of them, I have had multiple instances of severe phantom braking. They are quite alarming as the vehicle will drop 10-20mph on the freeway in an instant. These were always on large divided interstates (OH and PA turnpikes), and almost every time, there were ZERO cars around. I don't feel that I can even use the autopilot system at this point, for fear of getting rear-ended at 70 mph.

The car suddenly breaks while in the highway apparently for no reason. It happened multiple times in the last two months. It may cause accident by a following car.

I was driving southbound on Interstate 5 in California mid-morning on Friday, April 15th. Adaptive Cruise Control (Tesla "Autopilot") was set somewhere near 75mph. There was no other traffic anywhere near our vehicle (at least 1/2 mile clear both ahead and behind). There was no debris of any kind on the road or on the side of the road. The car suddenly and unexpectedly began heavy deceleration. It felt as if the vehicle was performing an emergency braking procedure to avoid a front collision. Fortunately there were no vehicles around, so other than startling me, there was no other incident caused. Had this occurred with a vehicle behind, it very likely would have caused a rear-end collision.

Since taking delivery of my new car on 2/8/2022, I have experienced at least 3 instances of phantom emergency braking, all while cruise control was in use. The vehicle suddenly brakes hard for 1-2 seconds. In two of these cases, a vehicle or person was visible off to the side, but not in my lane, and not where I would have had to brake. I am concerned that cars behind me could be unprepared for this sudden slow-down. While the car's software does allow for turning off the emergency braking capability, that action must be taken each time the car is started if you plan to use cruise control. For this reason, cruise control becomes a danger to use.

I275 southbound in Terra Ceia, FL. 11PM. Road surface damp. Speed 80 mph with adaptive cruise control engaged. No other vehicles within view. While on cruise control, the vehicle suddenly engaged the brakes slowing from 80mph to 65mph in a violent manner in a fraction of a second. Wheels broke traction slightly. This has occurred on a number of occasions to me since owned on 12/10/21. It's extremely dangerous to the point I rarely use cruise control on wet or slippery roads for fear of departing the roadway.

I have had this car for exactly one month, and on three separate occasions, while using cruise control, the car suddenly braked although there was no obstacle visible in front of the car. On one instance I was driving on a four-lane highway, and there was another vehicle rather close behind me, who was quite surprised by the sudden braking. On the two other occasions, I was driving on a two-lane road with no-one behind me. I don't think there was oncoming traffic in the opposite lane, but I can't be sure. I have searched on the web and found that there are other reports of "phantom braking" in the Tesla 3. Otherwise the car is fine.

Experienced the "phantom braking" phenomena traveling southbound on I-75/85 just south of Atlanta approaching an HOV exit on the left. The car was traveling with "AutoPilot" engaged, not FSD, at ~70 mph, and the brakes were applied hard as the exit to the flyover approached on the left. I did not lose control and simply stepped on the accelerator to resume the correct speed.

Have only had the vehicle on 2, 2 hour trips and have had the adaptive cruise control hard brake with no one around me or in front of me multiple times. It goes from 65 down to 50 or less in a second. Incredibly dangerous. Especially if I had vehicles behind me. Would've caused an accident no doubt. I hear about many teslas having this issue as well. Just give me dumb regular cruise control.

I was using traffic aware cruise control (TACC) on a two lane highway to maintain my speed. There was a car behind me and no cars in front of me. My car suddenly reduced it speed (braked) for no reason. I turned off the TACC at this point because its erratic speed control did not seem safe, especially with a car following me. Later, when no one was following me, I again tried enabling cruise control (TACC) on the two lane highway, and multiple times it would unnecessarily and abruptly slow down the vehicle for no good reason (apparently becoming confused by oncoming traffic safely in the other lane, when approaching a hill, when approaching barriers on the side of the road, and sometimes for no discernible reason). I will say that TACC works well on multi lane freeways, but in my experience was non-functional and borderline dangerous on simple two lane highways. I contacted Tesla and inquired about turning off TACC and turning on standard (dumb) cruise control when driving on two lane highways. They stated that there is no option for standard cruise control, only TACC. So the options are to completely disable cruise control on two lane highways (inconvenient, but probably the best option), or use traffic aware cruise control and just deal with its erratic behavior on two lane roads (not safe in my opinion).

While driving on the interstate and state highways using cruise control the car braked suddenly for no reason.

There have been 3 separate instances in unexpected and sudden braking when using cruise control. All instances occurred when there were no nearby vehicles present. The first incident occurred on a 2 lane road when I was driving in daylight. I used the cruise control and twice over 10 min the car suddenly and unexpected slowed/braked startling me. After 2 times, I turned off the cruise control. Another incident occurred when I was driving on the interstate. Same experience. Sudden unexpected emergency braking as if I was about to hit something and there was nothing there, again daylight. Most recent occurrence my husband was driving, it was night on interstate and he had cruise control on and the car suddenly braked startling everyone in the car. There were no other vehicles present. He turned off cruise control for the remainder of the drive.

The contact owns a 2022 Tesla Model 3. The contact stated that while driving at 65-70 MPH with the cruise control activated, the vehicle experienced phantom braking. The calibration in progress message was displayed. The failure nearly caused a collision. The dealer was made aware of the failure and scheduled an upcoming appointment. The dealer later canceled the appointment and informed the contact that the vehicle performed as designed and advised him to review the owner's manual. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 30.

Mileage: 30

Report Phantom braking. It happened multiple times on Thru way from last 3 days. There were nothing in the front of the car but it applied brakes on thru way, lucky no vehicle on the behind. I am concern about safety of my family.

While using auto-pilot, the vehicle suddenly applied brakes without apparent reason. E.g. while crossing an intersection and another vehicle crossing the same intersection in opposite direction, Another occasion was when climbing a steep slope on a two lane road. Yet another was on a four lane highway. I was in the right lane and another vehicle was in the left lane and ahead of me.

Using adaptive cruise control the car will often brake for no reason. This has caused me to not trust a system I was promised and paid for and I can't use any form of cruise control as there is no option for standard cruise control on the model 3 Multiple times during a trip the ACC will lightly apply the brakes when there is no objects in front of the car. About once per week of heavy use of ACC the car will slam on the brakes unexpected and for no reason. This has caused me to be honked at and almost rear ended on multiple occasions. I no longer use the system because of this. My ask is for the NHTSA to recall the model 3 and force Tesla to install radar on affected Model 3's. Vision only is a terrible system and Tesla greatly downplayed the pitfalls of it when I was purchasing the vehicle

The Tesla will slam on the brakes unexpectedly while using cruise control. It does this for no apparent reason and has almost cause several accidents including me being rear ended while cruising at 60mph.

No one around me on the interstate with my cruise control on. With no cars near me or any recognizable object to detect, the car phantom broke for me without warning. Nearly caused an accident for the car behind me.

While driving with cruise control set to 90 mph, my vehicle rapidly decelerated to 70 mph — with no other vehicles around. The vehicle suddenly braked for no reason at all, multiple times. Autopilot was not engaged and I was steering the vehicle myself. This while driving West on HWY 76 in Colorado a clear sunny day around mile marker 141, near Proctor, CO. The middle of nowhere. I have a 50 second video I would be happy to share but no video upload option.

Using the Autopilot system on a recent road trip, I experienced numerous incidents of “phantom braking”. I previously owned a 2018 Tesla Model 3 with witch I made the same 500 mile RT journey several times without ever experiencing this phenomenon. There were vehicles following mine in a few of these of these incidents which created a serious concern about a rear-end collision. I immediately reported the issue to Tesla service who confirmed the problem via remote diagnostics but did not offer any solution other than to wait for future software updates. The incidents occurred without prior warning in the form of messages or alerts of any kind.

With cruise control on the vehicle abruptly applied breaking system without driving involvement and quickly reduced speed from 85 to 60 before driver could engage accelerator to prevent chance of being rear ended. I have a video file if needed.

Tesla "Phantom Breaking" - Traveling at freeway speeds using cruise control, the car applied panic breaking without warning. There were no obstacles anywhere near the car. If I had not applied 100% throttle immediately I would have been rear-ended at high speed. The problem occurred with no obvious input and without warning. I am not able to reproduce it. I have not reported it to Tesla because the problem is well known yet Tesla has not publicly acknowledged it. There was a audible alert that sounded at the moment the breaking occurred, not before. The on-board camera system did not record the event. The car is new, Nov. 2021 delivery, I have driven it less than 1000 miles and this was the 4th, and most violent, "Phantom Breaking" event. I now consider the cruise control too dangerous to use. Because all of the other driver assist features depend on adaptive cruise control, they are now also useless.

While driving with cruise control on the vehicle will automatically brake for no reason. I was just on a road trip and had this happen multiple times while going 80mph. If someone was behind me it could have caused a accident and someone could get seriously hurt or possibly die. I scheduled service at the dealership and it sounds like this is a well known problem that does not have a fix. I could see this issue causing some bad crashes. I put 3/5 as the incident date, but this happens almost on a daily basis.

We just purchased this vehicle new one week ago. Several times while using cruise control on Highway 101 in Mason County, WA we have experienced severe "phantom breaking". There is no reason for the sudden breaking and seems to be quite random and dangerous.

When driving with Traffic Aware Cruise Control or Autopilot enabled, dangerous automatic braking occurs when the car senses conditions that do not warrant automatic braking. This unnecessary automatic braking occurs randomly when encountering overhead roadway signs, parked vehicles safely on the shoulder, oncoming vehicles fully in their lane on 2 lane highways, cross traffic that is far enough ahead of the vehicle that it is not a threat, and for no obvious reason at all. These automatic braking events are violent and slam on the brakes when they occur and create a danger from rear end collisions from other drivers since they are unexpected and occur for no obvious reason. Tesla service states that the Traffic Aware Cruise Control and Autopilot systems are Beta systems and thus require driver monitoring to maintain control of the car when using the systems and nothing can be done until improved software is developed and implemented. Driver intervention for unexpected violent braking is difficult because the events are unexpected and create driver shock which slows a reaction to slam on the accelerator pedal to stop the inadvertent automatic panic braking. In my vehicle, I find that the Traffic Aware Cruise Control and Autopilot systems are essentially unusable as they pose too great a risk of a rear end collision.

I have a 1 month old Tesla Model 3 that when i use the cruise control every time i go past a truck on a 2 lane highway, my car will initiate emergency breaking. This has caused cars to almost rear end me. I took the car to Tesla to be serviced, and the issue didn't get any better. I have videos of this happening if you need them

When Adaptive Cruise Control or Autopilot is active the vehicle will brake suddenly, often with no apparent reason. On flat roads, highways, clear weather and even no traffic from time to time it will randomly regen brake for no reason. The only time this occurs and is duplicated regularly is when driving on a single lane highway. Whenever a 18 wheeler is passing on the opposite lane the vehicle always regen brake suddenly, regardless of the position of the passing 18 wheeler even when it's apparent that the passing 18 wheeler is staying in its lane. Sometimes if the 18 wheeler has a wide load the regen braking is much more aggressive and the forward collision will give a warning. These instances can be overridden by pressing down on the accelerator and that will override the automatic regen braking. The problem with that temporary fix is that when I know it's going to happen I'm prepared but when the times it happens randomly I might as well just never use adaptive cruise control or autopilot.

Vehicle's adaptive cruise control is ON. Auto-steer is OFF. Vehicle rapidly phantom breaks under these observed conditions: 1. As the vehicle is passing a semi-truck with the semi in the lane immediately to the right. The camera shows the semi clearly in the lane to the right. The semi is not veering over into my lane. The cruise control seems to think (incorrectly) that the semi is in danger of coming into my lane. The vehicle rapidly slows by +/- 5 mph, which made a couple of folks following me irritated as my car is slowing and brake lights are coming on for no reason. I can decrease this reaction by the vehicle by steering the vehicle to far left side of my lane when passing the semi, but even then, it would still sometimes phantom brake. This happened about 15-20 times during a 2000 mile trip. This reaction by the vehicle, is decreasing safety, not increasing it. 2. Same condition with the adaptive cruise control on (auto steering off), passing a semi that is in the lane immediately to the right, but this time the car rapidly slows itself when I am about 5 car lengths back of the truck. This is an unsafe problem and needs to be fixed asap. If fixing it is going to take time, then Tesla should be required to turn off the adaptive function with cruise control so only speed control is functioning.

The contact owns a 2022 Tesla Model 3. The contact stated while driving 70 MPH with the Cruise Control activated, the phantom braking system engaged inadvertently, and the vehicle almost came to a complete stop. There were no warning lights illuminated. The contact depressed the accelerator pedal and was able to continue to drive the vehicle. The contact stated that the failure had been reoccurring daily while driving. The manufacturer was notified of the failure an informed the contact that they were working on the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 150. The VIN was not available.

Mileage: 150

Multiples times while the car was using cruise control we have had it unexpectedly and aggressively brake. This seems to happen when a car is coming towards us in the opposite lane. We have only had the car for 4 days. It is to the point we do not use the cruise control. If someone would have been behind us we would have gotten in an accident. We have also had the forward collision warning go off while not in cruise control.

Using auto pilot on highway car would apply hard breaking for no apparent reason. Several times this nearly caused crash as cars that were behind me has to swerve to miss hitting us. This happed at least half a dozen times. Most of the breaking was quick and abrupt, but at least twice they were abrupt but took the car from 75 to 20 on the interstate.

I was using "Autopilot" on a 4 lane divided highway. There were no other vehicles on my side of the road, nor on the other side. There were no close objects, vegetation or buildings. I was going 65mph (the limit for the road) when the car suddenly, without any warning braked very hard and the speed fell to 47mph in a a second or two. I quickly cancelled Autopilot and regained control. This has happened more than 20 times during in 3 weeks of driving this Model 3 Long Range AWD. It has occurred with the speed set at 45, 55, 60 and 65. In the media, this is referred to as "phantom braking"

Driving on a 4-lane limited access road while using adaptive cruise control (Tesla calls it "Autopilot", my car suddenly reduced speed dramatically. There were no other cars nearby, nor was there any kind of obvious obstruction. I was able to turn off Autopilot and resume speed, but I worry what might have happened if there had been another vehicle behind me.

The adaptive cruise control system (Autopilot) brakes even when there's no obstacle on the road, or if there's a truck on the opposite lane. This also triggered the forward collision warning system. If there was a vehicle behind me, this would've caused a crash

The contact owns a 2022 Tesla Model 3. The contact stated that while driving 75 MPH, the braking system erroneously activated causing the vehicle to abruptly stop. The contact indicated that prior to the braking system activating, an audible beeping noise was heard inside the cabin. Additionally, there was no vehicle or object nearby to cause the Forward Collision Avoidance system to be activated. The cause of the failure was not determined. The local service center was notified of the failure. The manufacturer was not contacted. The failure mileage was 1,800.

Mileage: 1,800

When driving in cruise control on a 4 lane highway (2 in each direction) the car automatically went into a hard brake, slowing down approximately 20 mph. The car returned to cruise control and 5-10 seconds later did the same thing again. There were no cars within roughly 1/4-1/2 mile in front of the vehicle, but there were cars heading in the other direction in the lanes traveling the opposite direction.

- Cruise control and Autopilot are causing rapid and unneeded emergency braking. This issue essentially renders the car unable to reliably use basic cruise control capabilities - Unneeded braking can cause an unintended rear collision by someone following behind the vehicle, also raises blood pressure of drivers and passengers in the car when braking happens violently and unnecessarily. - Issue hasn't been reproduced. But others I've spoke with are experiencing this on the Tesla Model 3 - The vehicle hasn't been inspected by anyone. - There is no warning audibly or visibly in the car. However the problem seems to occur when the car can't determine if an oncoming car or other obstacle is in the actual lane of the direction of travel or not. My guess is that this has to do with the vision system that's tied into autosteer and cruise control

The contact owns a 2022 Tesla Model 3. The contact stated that while driving at 70 MPH with the cruise control activated, the vehicle experienced phantom braking. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 6,000.

Mileage: 6,000

While using adaptive cruise control, the car suddenly braked on Interstate at 65 mph when no obvious obstruction was seen. There was one truck over 100 yards ahead in the slow lane. The braking occurred after I changed lanes to pass. There were no vehicles ahead in the passing lane. Despite a light rain, visibility was not overly affected.

Just purchased a new Tesla Model 3 (long range) yesterday. On the drive home, I engaged the cruise control after the car reached its required calibration distance of 50 miles. Occasionally, but without warning, the car would automatically apply the brakes with no car or other visible obstruction ahead of me on a long straight road. The brakes were applied so firmly that the car would have come to a complete stop within 200-300 feet if I had not engaged the gas pedal to stop the braking action. The suddenness of the braking forced the car behind be (my wife, who was following at a safe distance) to aggressively brake in order not to rear-end me. This happened 3-4 more times during the 120-mile drive home, so I finally disengaged the cruise control and "manually" controlled the accelerator by foot for the last 20 miles of driving, without further incident.

Potential computer system/programming issue. TACC autopilot issue. Highly numerous amount of 'phantom braking' events, potentially could cause loss of vehicle control and/or rear end collision. Also, auto-dimming headlights issue, in that oncoming drivers could experience blinding high-beam lights due to the fact that the lights do not dim automatically until the oncoming vehicle is very close. This is potentially a high risk for auto accidents. Again, high amount of phantom braking!!! These issues are ongoing issues, and started upon delivery of my vehicle, new, in December 2021. Tesla service will not address these issues.

When driving my husband's new Tesla on the highway for the first time, with adaptive cruise control on, there were two frightening incidents: 1) I was traveling in the left-most lane of a 3 lane highway (3 lanes in one direction) moderate traffic. I signaled my intention to change lanes, and started to migrate into the middle lane. There was an 18-wheeler in the right-most lane slightly ahead of me. The Tesla suddenly braked hard without warning. Either I or the Tesla also swerved back towards the leftmost lane (it happened very fast and I was panicked, so I'm not sure which of us initiated the swerve). The Tesla then seemed to recover from being "spooked", and accelerated back up to the set speed. 2) Later that day, I was traveling on a highway again, this time just two lanes in one direction. Traffic was light. The Tesla again braked suddenly, though there were no cars nearby, and then resumed speed. Additionally, when driving in moderate traffic in town, the Tesla let out loud alarms twice to alert me about cars it deemed I had not paid sufficient attention to as traffic slowed approaching a light. Cruise control was not on, and it did not brake, but it was startling. I usually drive a 2017 Volvo V60 with adaptive cruise and collision-avoidance technology, and it is MUCH less sensitive than the Tesla is.

While driving with the adaptive cruise control enabled or the autopilot enabled, the car will do a hard braking episode which may reduce the speed from 60mph to 40 mph about a fast as is possible without locking up the tires. This happens on four lane divided interstate driving as well as two lane undivided driving. In either type of driving, there may not be any traffic anywhere in site. The most common condition for the occurrence of the braking is while using the adaptive cruise control on a two lane highway and a large truck or farm vehicle approaches from the other direction while driving in the center of their lane. The car acts like it has detected a possible collision, annunciates the collision warning, and brakes hard. I am reporting this because it is obvious to me that this is a safety defect. If someone were following behind me, even at a range considered safe, the deceleration is fast enough to cause the car behind me to collide with me. These hard braking episodes will happen as many as 4 or 5 times in a full day of highway driving. Many smaller episodes of less dangerous braking occur throughout a full day of driving and I consider them annoyances. I received my new car in January of 2022 and have driven it 4300 miles. The car has exhibited this condition since the fist time I tried to use these features starting February 3, 2022. I will not use the cruise control or autopilot when passengers are in the car because it is very alarming to them when it happens. I now rarely use autopilot when I am alone because of the constant state of fear that an uncontrolled braking will happen which would cause an accident. I would be happy to share further information with you. I am aware of the investigation that you began last week looking into the phantom braking phenomenon for Tesla owners. From reading the Washington Post article on the subject and then various posts on Tesla forums, my experiences match the phantom braking descriptions.

Can’t believe there are a few hundred reports of phantom braking. This is essentially a standard feature of the car. Nearly every other highway drive using autopilot the car will hard brake for nothing. Most recently was Tuesday around 11pm on highway 91 between hartford and new haven, CT. In the right lane of the highway traveling at about 67 mph the car abruptly hit the brakes. I am accustomed to hovering my foot over the accelerator so was able to reengage and regain cruising speed. Luckily no car was behind me or anywher near me. There was no overpass, exit ramp, flashing lights or anything else obvious that might have caused the hard brake. I’ll not while I’m here that the auto brights feature is bizarre and potentially dangerous. Autopilot turns on the brights when there are no cars immeadiately in front and this can only be disabled per incident. When is it ever a good idea to have the brights on on a 3 lane highway during normal traffic hours? Annoying, sure, but could actually cause problems distracting or blinding other drivers

I had multiple episodes of phantom braking while at highway speeds on cruise control. Most were small taps on the brakes that I could feel. There was one instance of a sudden 20mph drop from 67mph to mid forties and a second similar one they also resulted in the alarm within the vehicle going off. There were no vehicles, pedestrians, or other objects in the road in front of me and no reason for the car to brake.

In a 90 minute stretch of 2 lane highway on the way home from vehicle delivery, the car “phantom braked” for every semi-truck and most taller pickups which were approaching in the oncoming lane. At least 100 times on this maiden voyage. This unwarranted hard braking is unacceptable and unsafe.

Good evening, we took delivery of our Model 3 just over a week ago and have a big concern with Autopilot. Over a dozen times thus far, the car disengages Autopilot and begins to brake. This is MUCH worse at night when approaching hills or other cars and is very unsafe, especially for the people behind us. Is there a feature I can turn out to improve this? Perhaps add STD Cruise w/no emergency braking? Help!!!

On multiple occasions in different environments the autopilot system has randomly braked/slowed to a dangerous level. This has occurred during city and freeway driving. It has not yet caused an accident, but I am now hesitant to use the feature in most situations. There is little consistency or understanding as to when or why this occurs. Please analyze the situation and require Tesla to remedy this problem.

While driving down the freeway in auto-pilot this morning, I was in the middle lane and somebody in the right most lane put on their turn signal to indicate that they were planning on moving into my lane after I passed, but my car suddenly panic-stopped from 65 to almost zero all at once, and I almost got rear-ended. It completely scared me, and I disabled auto-pilot for the rest of my drive to work! My car’s only 5 days old, and I now have anxiety about its auto-pilot capabilities!

The contact owns a 2022 Tesla Model 3. The contact stated that while driving at various speeds, the vehicle would independently downshift while in cruise control while passing semi-trucks driving in the opposite direction of traffic. The contact stated that while driving to work on one occasion, the failure occurred fourteen times. The contact stated that there was a beeping sound coming from the vehicle during the failure. The contact had called a service center where he was informed that the failure was normal vehicle operation. The vehicle was not diagnosed or repaired. The failure mileage was 0.

While driving on the highway my car suddenly decelerated almost to a complete stop while going 60+ mph. It happened when I went under an overpass and there was a dark shadow on the road due to the overpass. It also happened when I was driving in the direction of the sunset which caused a big glare on the road.

Phantom braking when using either cruise control or auto pilot. This happens during the day and night. If there is a car on the other side of road, it will brake very hard. This happens on one lane highways or large freeways. It is extremely dangerous especially if you have another car behind you. It will go from 80 mph to 50 mph in one second.

Just bought the car a few weeks ago. Have had several instances of phantom breaking. Can't drive down a residential street at 25mph as the cars parked along the side of the road cause the alarms to go off and the breaks apply themselves. Also happens when driving on 3 lane roads with a middle suicide lane and there is a truck parked in the middle lane suicide lane. The car will apply emergency braking just driving past the truck. Or past a school bus that is off the side of the road. Very irritating. My subaru has never done this. Multiple dates this has happened

Phantom braking occurs when 'autopilot - cruise control' is engaged, while traveling at highway speeds.

My vehicle is experiencing a significant number of phantom braking events. The issue seems to be primarily contained to two way roads, more often when traffic is coming from the opposite direction, more often at night, going through intersections, at the crest of hills, and when there's no lead car in front of me in my lane. Without a lead car in my lane on 2 way country roads, it's not uncommon for the vehicle to rapidly decelerate, somewhere between 10-30 mph for around 3-10 seconds per instance, at least once per mile or so driven.

I have reported to Tesla that my brand new 2022 Model 3 is braking and indicating far ward Colli on warnings when there are no issues present on the roadway. I have submitted well over 50 bug reports within the past month detailing these incidents when they happen. Each of these incidents are a safety hazard. Unexpected braking not only is scary, but also causes problems for vehicles following behind me. I’ve had other vehicles nearly collude with my vehicle from behind (due to my car quickly decelerating for no reason). I’ve also been on the receiving end of some road rage incidents because my car is slowing down for no reason, people think I’m brake checking them or trying to intentionally cause a rear end collision. I have sent my concerns to Tesla on three occasions. They have not investigated my specific claims and only respond to say that the behavior is “normal” for the software and hardware configurations within the vehicle. I’m not sure how a system that can be this unsafe can be considered “normal”

Phantom Braking

2022 Tesla Model 3 Long Range. As already known the Tesla Model 3 has the issue of "Phantom Braking". Now that I have a $65,000 for 3 days I am very angry and concerned about the phantom braking. Here are some details. Within 10 minutes of initiating Autopilot or Cruise Control the vehicle brakes without any reason when driving highway or freeway speeds (I did not try it on city roads). For the most part the vehicle unexpectedly decelerates 2-5 mph. Although, it is just a little bit it makes for a very unpleasant ride. However, it happens repeatedly. And this happens all the time when Autopilot or cruise control is activated. I counted 5 occasions of phantom braking within less than 3 minutes. The last of those 5 was an unexpected and heart stopping deceleration from 84mph down to 52 mph in less than 2 seconds. This can really give you a heart attack because it is very unexpected. You cannot even drive 10 miles without this happening. There wasn't even a car in front of me for at least 1 mile. So no reason whatsoever for this braking "maneuver". Since I have read about this issue I only (if even) try cruise control or autopilot when there is no vehicle behind me within 1 mile to avoid someone rear ending me. But still.....it is a serious safety issue. One, because of following traffic rear ending the vehicle and second it is really HEART STOPPING when for no reason, out of the blue your vehicle decelerates very HARD. Thank you.

We took our first out of town day trip of about 400 miles round trip, mostly freeway driving, last week 2/19/22. I tried using Tesla Traffic Aware Cruise Control several times during the trip, and we experienced at least 3 episodes of the "phantom braking" that I have read about. On those occasions, the system abruptly sounded alerts and braked automatically while cruising at about 80 mph (speed limit 75). There did not seem to be any obvious reason for this braking on the freeway on two occasions. There was one episode on a two lane section of straight highway, cruising at about 70 mph, when a large semi truck/trailer passed us in the opposite direction, both of us staying in our lanes, when the TACC sounded alert and applied brakes abruptly. I am very reluctant to use this function now until Tesla resolves the issues involved. It is very disconcerting and potentially dangerous when these events happen. I did send a "bug report" to Tesla from the vehicle the day after this happened. No response as yet.

Car will brake for no reason at all. Hazardous for any cars behind the vehicle when it randomly brakes.

Brand new Tesla Model 3, driving 60 mph on 2 lane highway. The shadow of an oncoming 18 wheel truck was cast into my lane, as it was oncoming, probably 60 mph as well. I believe the shadow triggered the "Automatic Emergency Braking", and my car violently slammed on the brakes, and released them about 30 mph. If there was a vehicle behind me, there almost certainly would have been a collision. Thankfully, no one was behind me, and my car never left the proper travel lane.

Phantom braking keeps occurring when my cruise control is set. If there is oncoming traffic with their headlights on in the opposite lane, my car will begin to brake. It also occurs sometimes when there are no other cars nearby.

My car when it’s on cruise control will all of a sudden have phantom breaking issues causing it to decelerate very quickly almost causing many crashes with cars behind me. This issue needs to be addressed quickly before someone is injured or even killed

I purchased this vehicle 10 days ago and have had “phantom braking” about a dozen times already. Some more drastic than others. Most cases was at night and most cases there were absolutely no objects that should have triggered the vehicle to rapidly slow down. It is extremely annoying and dangerous as I went from 75 to 60 in about a second. It seems to happen more when there is little traffic in front of me than when I am moving along with a lot of traffic.

The vehicle will randomly SLAM on its brakes while traveling when autopilot or even just regular cruise control is engaged. We will be traveling 85 MPH and the car will randomly hit the brakes and drop down to 65 MPH in about 2-5 seconds. There are no other vehicles in front, but can sometimes be behind. It is extremely dangerous and could cost people their lives. These kinds of incidents will happen 15-20 times on a 150 mile road trip of all freeway driving.

The autopilot applies the brakes when there is no obstacle in front of the car. One example - I was driving @ 60 mph on an entrance ramp from I-10 to SH 99 with the cruise control engaged but not the full autopilot (no lane keeping assist). There was a spot in the highway approximately 50 yards ahead where there was a slight dip and oil and lubricants had made a dark spot on the roadway approximately the size of a small car. Without any input from me the car slowed quickly from 60 to @ 30 mph. Fortunately no one was close behind me. Another example - I was driving @ 70 mph on SH 99 with the autopilot engaged. As we approached a gentle left hand turn the system apparently picked up the concrete guardrail as an obstacle and braked the car from 70 mph to @ 40 mph. As the autopilot continued the turn and maintained the lane the car sped back up to 70 mph. No one was behind me but there were cars in the lanes next to me that reacted when my car slowed down and sped up. My car is a 2022 Tesla Model 3 Dual Motor Long Range. It does not have the full self driving option.

This vehicle suffers from frequent, intense phantom braking/automatic emergency braking, as well as frequent false forward collision warnings. The phantom braking puts us at significantly increased risk of being rear ended. The incidents are so frequent that the ADAS systems are essentially unusable. The constant false collision warnings have conditioned me to ignore the forward collision warnings, so if there comes a day when a real forward collision warning occurs, I'll have been conditioned to ignore it, possibly to the detriment of my safety and others. Tesla needs to communicate a a plan to prevent phantom braking and false collision warnings.

Phantom breaking issues..very dangerous

Phantom breaking issues..very dangerous

The car regularly brakes unexpectedly at highway speeds when the cruise control is engaged. It is behaving as if it detects a car in front and is trying to avoid a front end collision but there is no object there. I wonder if some debris or something flies in front of the camera and the car interprets it as another vehicle.

Just bought the in November and I experienced the phantom braking few times on the street without cruse control active and also on the freeway with and without autopilot on, on the street almost got rear ended.

Phantom Braking. Yes my safety and the safety of cars behind me were put at risk by the sudden braking. I have not contacted the dealer yet. There was no warning prior to the issues occurring. I sure wish I'd known about phantom braking before I set off on a road trip across I-70 recently. Very dangerous indeed. I drove my 2022 Model 3 from Denver to KC round trip last weekend and phantom braking occurred about 30-40 times total. I was using TACC cruise control and going about 75 MPH during these times. I didn't want to turn off TACC cruise control because the roads were straight and it was a 9 hour drive, but I did drive with my toe on the accelerator to be safe and was always on guard, especially when cars were directly behind me. It would suddenly brake when the pavement texture changed, under an overpass shadow, after a bridge and randomly when I had no idea it would occur. I was afraid of getting rear-ended and it made for a pretty tense trip. I sure hope it gets fixed or I won't be taking it on extended road trips. It would be a shame to not be able to safely use cruise control. Also, makes me aware of other Tesla's out there that might phantom brake as well so we need to be careful. Unacceptable and dangerous.

When using auto pilot or adaptive speed control the vehicle seems to see shadows or things that aren't there and brakes hard. It's happened several times and fortunately no accidents have occurred.

When driving on highway with “autopilot” engaged…. Vehicle brakes for no apparent reason at random times. Super dangerous especially if someone is following you. Vehicle brakes hard and is not safe

Driving on the highway, traffic is slowing in front of me and automatic braking kicked in and made the vehicle come to a full complete stop. I can normally override the brake by pressing on the accelerator, but it continued to stop, with several vehicles behind me slamming on the brakes because my vehicle wouldn’t move. Vehicle in front of me was a quarter mile ahead before I could move again.

Driving on a two lane highway with adaptive cruise control on, the car sometimes decelerates and sometimes even comes to a quick stop with brakes when a vehicle approaches from the opposite direction. Although it does not happen every time, tractor trailers turn red and the car slows from 55 mph to 10-20 mph rapidly. Cars behind me have nearly hit me in the rear because of the fast stop where none was expected (or needed). On occasion, the car slows when no car is coming, but there is a rise in the road, or a curve. In Rochester, at Tesla Service, I was told that the adaptive cruise control was "performing within specifications." If that is correct, the specifications are dangerous and need to be modified. The only remedy, I was told, was not to use adaptive cruise control.

The car brakes by itself. It seems to happen when there is an oncoming car in the opposite lane. The car slows down; it does not come to a complete stop but it is obviously dangerous enough that I will not use the cruise control

On January 25, 2022, between approximately 7:30am and 8am while using cruise control, the auto suddenly braked three separate times between the above stated times. The third incident was so violent, that the passenger was thrown toward the dashboard and the driver pulled over to the shoulder to allow traffic from behind to pass. The incident could have caused a rear end collision given the sudden, involuntary braking. This was the first opportunity to engage the cruise control given we were driving a long distance at between 60-70 mph. Cruise control was disengaged after this incident and not used the balance of that trip. On February 8, 2022, at 7:44 am while using cruise control at approximately 65 mph, the vehicle again braked. The driver disengaged cruise control and did not use it again during that trip. The incidents have been reported to Tesla and there have been no explanations of the phantom breaking nor any assurance that the issues will be addressed. Given the breaking occurs at random times at high speeds while using cruise control, it is a dangerous condition and likely will cause rear end collision at some point. Would request that the issue be address and the phantom breaking be eliminated.

2022 Tesla Model 3 experiences sudden and unwarranted braking. Vehicle will use Autopilot and suddenly brake on roads. Commonly known as “Phantom Braking.”

2022 Tesla Model 3 experiences sudden and unwarranted braking. Vehicle will use Autopilot and suddenly brake on roads. Commonly known as “Phantom Braking.”

When using cruise control or Autopilot the car will all of a sudden slam on the brakes. This has the potential of being rear ended by the car behind me. This is usually when a larger truck is approaching in the on coming lane and I suspect the Tesla thinks it is about to hit it. This happens so often that I cannot even use the cruise control feature.

When on two lane roads and adaptive cruise control is engaged, the car ghost brakes when larger on coming vehicles are detected. This sudden braking could cause other cars to hit my car from behind. This occurs frequently. I reported this to Tesla during a service visit and they did something that didn't help. They did say to report back if it didn't help. I'm reluctant to use the adaptive cruise control.

Phantom braking on the highway. No other vehicles in my lane or the lanes next me. Vehicle slammed on brakes and warning chime sounded

Phantom braking on the highway. No other vehicles in my lane or the lanes next me. Vehicle slammed on brakes and warning chime sounded

Driving 45mph on an expressway. The wind blew apple blossoms off the trees beside the road. The posed no danger nor did they cause a visibility problem for me. The cruise control slammed on the brakes and I was nearly rear-ended.

The automatic emergency braking system activated for no reason while driving northbound at night in the right lane on MA Route 24 as I approached the intersection with MA Route 79. At the time of the incident, there were no vehicles in front of me, nor were there any vehicles entering from Route 79. The adaptive cruise control system was engaged at the time of the incident. This has happened on several occasions at that same intersection under the same conditions. It has also happened when I've been driving in the left lane on the highway and passing a tractor-trailer in the right lane. The sudden, unexpected deceleration put us in danger of being rear-ended by traffice behind us, creating the possibility of a multi-vehicle, high speed collision. The problem hasn't been reproduced or confirmed by the mfr, police or others. The vehicle has not been inspected by the mfr, police, or others. There were no warning lamps, messages or other symptoms of the problem prior to the failure.

Phantom Braking - Severe, very large number of instances since taking delivery of this auto in December 2021. Severe risk of rear-end collision should this occur when being followed closely. This occurs very often. On a 13 mile drive this morning, 2/19/2022, phantom braking occurred 12 times. The Tesla repair center repeatedly cancels an appointment made to address this issue, stating that 'it's normal for this to occur. Remember, autopilot is a Beta function'. The one time that I was able to have the vehicle seen by the repair center, this is what I was told. Warning chimes do sound. However, this extreme braking is unsafe, and could possibly result in loss of control if it occurs on slippery roads.

Vehicle brakes on cruise/autopilot for no reason occasionally

On cruise control, on a 2 lane highway when a tall truck is coming in the opposite direction, the car breaks as if it was going to be a head on collition. I reported to Tesla service and I was told not to use cruise control in a 2 lane highway.

Phantom braking on open roads. Occurrences: Twice on February 16, 2022 Twice on February 17, 2022

Car randomly brakes while the autopilot feature is turned on, it has also happened while just in normal cruise control. Car will brake unexpectedly even in broad daylight on a straight road with no other vehicles around.

I was travelling on a 2-lane road at 50 mph using the car's autopilot (adaptive cruise control). As a pick-up truck approached me in the opposite lane, the car beeped loudly and applied the emergency braking at great force, reducing the car's rate of speed from 50 to 25 mph.

When I drive this car in cruise control, I never know when it will suddenly brake without warning, trying to bring the car to a stop whether I am going 65 or 30 mph. It will see a shadow in the road, a pedestrian on a sidewalk, an oil spot on the pavement, and will abruptly throw the car and me into rapid deceleration. If it is sees a car in the oncoming lane, driving appropriately in its own lane, my car in the opposite lane will suddenly brake like I am about to have an accident. It will brake if it sees a vehicle coming around a bend in the opposite lane. Not only is my vehicle's braking uncomfortable and alarming, it is exceedingly dangerous. On urban and semi-urban highways, multiple times someone has almost rear-ended my car. Only because I was hyper-alert to the situation was an accident averted. I am an excellent and conscientious driver, with both hands on the wheel, not using my phone. I am not using the "self-driving" mode and never have. It is an option I paid $10K for but have never used. My main concern is for the safety of my current vehicle and for the other cars on the highway around me.

When driving on two lane roads using adaptive cruise control, the car will often decelerate or brake suddenly when there is oncoming traffic or lighting conditions change. There is no warning when this happens. I recently made a 200 mile trip and this occurred at least 15 times during the drive. I felt unsafe especially when there was a vehicle behind me.

When cruise is turned on the wipers turn on. This was their response. Hello Dominic, This is Ken from Tesla virtual service center. We have been getting some push back on the most recent update doing what you are saying regarding autopilot/autowipers. Our auto wipers and sensors with our windshields need improvement and is still in beta. I am not sure why the factory has decided to lock in the auto wipers function during autopilot for that reason on last months firmware update. Your comments along with others have been reported back to the factory to provide feedback to them on the problems you are facing as a customer. Unfortunately, there is no way for us to override this or turn it off. hopefully it will no longer be the case after the next update but a mobile tech coming out on the 19th will not be able to rectify this concern.

I was driving on the highway with cruise control activated at 60mph. The vehicle randomly broke and slowed. No other car was on site and no other person or object was around us. This has happened several times. This random braking on cruise control. This is dangerous. Please help with this issue and let me know what the next steps are. Thanks.

Took delivery of 2022 Tesla Model 3 on Wednesday February 16, 2022. 3 incidents since taking delivery when autopilot adaptive cruise control is engaged and car randomly slams on brakes. 2 incidents with no known hazard in view of direction of travel and the other when approaching oncoming traffic driving in opposite lane. No indication (such as beeping on normal lane departure) that the vehicle was going to engage automatic braking.

I only picked this car up on 2/16/22. Several times with the cruise control or autopilot/autosteer engaged on a two lane road the vehicle braked suddenly and severely in response to semi-trucks in the oncoming lane.

I have experienced the phantom braking problem commonly reported on in the news. On several occasions when the cruise control is set, the car will randomly slam on the brakes endangering my safety and those around me. This has happened on city streets in a 45 MPH zone (for no apparent reason), a 2 lane state highway (when a car approaches from the other lane traveling in the opposite direction of me), and on an interstate (when approaching an overpass). This happens very frequently regardless of whether I use automatic steering. I have not taken it to a service center or otherwise reported the problem as it appears to be common amongst other owners of this make/model.

I was driving on the highway on autopilot, I had my vehicle traveling at around 75mph when suddenly it slowed down abruptly all the way down to 58 for no reason at all. There were no cars behind or around me. Phantom braking is a real thing.

I purchased from Tesla Motors, Inc. (“Tesla”) a Tesla Model 3, VIN: [XXX] (the “Defective Vehicle”) and took delivery of the vehicle on December 10, 2021, from the Loveland, Colorado, service center located at 1606 N. Lincoln Ave. (the “Service Center”). Since the day I took delivery of the Defective Vehicle in December 2021, the Defective Vehicle dangerously, suddenly, and repeatedly slams on the emergency brakes while I am driving on the two-lane roads that are my route to commute to work. This defect has existed and the Defective Vehicle has been unsafe and noncompliant with Tesla’ warranty since the day I took delivery of it. The defect substantially impairs the use and market value of the Defective Vehicle, as the Defective Vehicle is a danger to anyone who drives it. My daily commute is approximately 25 miles each way to and from my home, and, on average, the vehicle will slam on the brakes no less than fifteen times per commute. Often, the occurrence is much higher than fifteen times per commute. Vehicles following behind me have had to swerve to avoid the Defective Vehicle and my belongings fly into the dashboard. One morning, the emergency braking caused my vehicle to slip in the snow, and I was fearful I would hit an oncoming vehicle head on because of the unexpected emergency braking. This defect is severe and endangers my life and safety and the life and safety of any passengers. I have attempted several to have the vehicle repaired at the Service Center, but the Service Center has either refused or been unable to bring the Defective Vehicle in conformity with the warranty. I have asked repeatedly when the repairs will be made, but no one at the Service Center responds to me in the app and the Service Center unilaterally cancels and closes service appointments I attempt to make. I have notified Tesla that the vehicle is a Lemon under Colorado law. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

The vehicle when autopilot is engaged, sometimes when passing large vehicle like a semi truck or for no reason the vehicle will slam on the breaks, sounds warnings for forward collision. Could cause an accident if traffic around is paying attention or a road rage incident. Phantom Braking it's mostly called

The vehicle suddenly brakes quite significantly and without warning periodically when cruise control or automatic steering is in place. It happens most often on two lane roads when a truck or a vehicle with headlights on approaches in oncoming traffic. There is no warning and it is so startling that it causes the driver to overcorrect or worry that the car will completely stop with traffic moving behind us. It is totally unpredictable and unanticipated. Once the vehicle has passed, it rapidly resumes speed. It feels as if the car has total control, not the driver. I have not notified Tesla, but plan to. Very dangerous and unnerving.

I own a 2022 Tesla model 3 I am having issues with the Problem known as Phantom Braking which occurs while driving in cruise control. This happens somewhat randomly but especially when the road takes a curve, or when a large vehicle comes in the opposite direction. For example, if going 60 mph, it brakes immediately to 30 mph, and if going 30 mph, it brakes fast to 15 mph. This results in groceries sliding forward and seat belts being activated, not to mention the car behind having to brake to avoid a collision. The Tesla service department says there is no fix for it, it is just part of the current full self driving package.

Driving on I-26, 4:30am, no cars around and my car aggressively brakes causing me to react quickly and disable smart cruise control. Making a return trip 1 week later on I-95, the car at various times brakes for no reason multiple times on a700 Mile trip.

Using the Autopilot cruise control for the first time, the vehicle was traveling at the speed limit when it suddenly began braking at an aggressive rate. Since the vehicle is brand new to us, and this being our first Tesla, my wife and I thought that maybe we did something to cause the braking. We tried the autopilot cruise control again later that evening and the vehicle did the same thing. Luckily, there was not a vehicle behind us on either occasion or else we would have been rear ended. This is extremely unsafe. How can you feel confident enough to drive on cruise control when the vehicle randomly brakes at an aggressive rate? This is going to get someone killed, if it hasn't already.

While using adaptive cruise control, the car would often brake for no reason. This seemed to mostly occur when going over the crest of a hill.

Phantom braking on highways, multiple times on full self driving (auto pilot)

I have approximately 3300 miles on the car since new. I cannot safely use the adaptive cruise control feature because the car randomly applies significant braking. This has happened about 10 times in a variety of conditions including completely clear with the car recently cleaned.

car will put on brakes when in cruise control with no warning and without a danger of collision happens fairly frequently

This issue happens only on one side of an highway (I-76E), otherwise I have not noticed it elsewhere. When using cruise control or autopilot, the vehicle changes the max speed from like 65 to 45 or 50 mph (in 65 mph highway). It happens in 4/5 places on the highway where it reduces the speed of the car abruptly. This may cause rear ending of the vehicle if there is a closely following vehicle.

There are two problems with our new 2022 Model 3. 1) The car randomly "phantom brakes". I counted on Monday-- 5 times in roughly 50 miles including twice from 75 MPH to under 40 MPH with maximum braking. All events were on a wide open freeway in a rural area with very light traffic and no movement or vehicles that would possibly explain it. The phantom braking is so bad that the car isn't safe to drive. 2) ABS malfunctioned resulting in a very slow speed impact. A car stopped abruptly in front of me, I hit the brakes where ABS kicked in, the car also automatically braked, but the deceleration was no more than just lifting my foot of the throttle. The ABS was chattering audibly and pulsing through the brake pedal so the ABS was definitely triggered but it appears it was falsely sensing wheel lockup when there was none. If I had been able to just lock the tires up or modulate the brakes myself to prevent lockup, the accident would not have happened. For ref, I'm 52, I've been driving since I was 15, and I have roughly 1,500,000 miles of driving experience. I ride motorcycles and am also a commercial pilot. This is the first accident involving another car I've ever had (never been hit or hit anyone). Tesla has refused to provide the crash data recorder info stating that they are not required to do so in Texas. Based on a conversation in person with a Tesla technician, it appears this is a very new policy with Tesla. At the risk of being accusatory, there are very few reasons Tesla would refuse to provide this data and most if not all of those reasons are to prevent owners from getting data that shows the car malfunctioned. I do have the camera video showing the accident and you can see at 20-25 MPH, I was in full ABS roughly 3 seconds before impact. This was on a dry, clean roadway. I'd guess I should've stopped in 1-2 seconds easily and my 8,000 truck can stop much shorter than what the Tesla stopped in.

On multiple occasions while driving at highways speed on freeways, vehicles adaptive cruise control activates emergency braking when there are no obstacles in front of the vehicle. Cause of braking appears to be caused by high contrast shadows from overhead signs, billboards, and other tall vehicles that are on the road. This has caused moments where an accident could occur from the vehicles emergency braking activating when there is no actual reason that the system should activate. It also creates concern for the use of the cruise control system and autopilot while driving on the freeway.

We have experienced 6 or more incidents of phantom braking in the few weeks we have owned the car. This mostly seems to occur on sunny days when there are distinct shadows in the road. This mostly occurs on highways at high speed and typically slows the vehicle down well below the speed limit prior to correcting itself. It has also occurred once at lower non-highway speeds. It is concerning mostly because it could easily cause an accident whereby the person behind me is unable to stop in time.

When using the autosteer function and also the adaptive cruise control, the vehicle seems to have a phantom braking issue. The car will apply brakes in an aggressive manner when the vehicle is faced with oncoming traffic in the opposite lane headed the other direction on a 2 lane road. This seems to occur when a large truck such as UPS or semi tractor trailer is approaching in the other lane headed the other direction - the vehicle seems to recognize that as an imminent forward collision and begins to aggressively brake the vehicle, which could cause a following vehicle to rear end me. This has happened on several occasions with varying degrees or severity (how hard it applies the breaks)

On two occasions I've been driving on a highway using autopilot at 70 MPH and the car started to brake for no reason. During one of the incidents the car also started to steer to the right and also cause a crash.

Have had several phantom braking espisodes when driving with cruise control on both at 45 mph. It brakes by itself and there is nothing in front of me that would of caused this

My car suddenly braked for no reason. I was at risk of a rear-end collision. I called Tesla and they instructed me to reboot my computer. They said an engineer would review the computer records and get back to me. No follow-up has happened yet. No, the vehicle has not been inspected. Before the incident, I heard a warning signal.

On several occasions, while using adaptive cruise control and/or autopilot, the vehicle sharply slowed or braked with no apparent obstruction or threat. It once happened while cruising at 80 MPH on freeway 10W in Phoenix, in the carpool lane. There were no vehicles within a concerning distance in front or behind me, so I was not necessarily at risk - but certainly would have put myself or others if there had been more traffic in the lane. The same happened while on a 3-lane road (Queen Creek Road between McQueen and Arizona in Chandler) this morning. Adaptive cruise control was set at 56 MPH when vehicle suddenly braked and slowed without any visible threat or danger. Again, there was not traffic near me (front or rear), so no significant risk. No warning chimes or messages were given prior to any instance of braking. The problem has not been inspected/reproduced/confirmed by a dealer or service center.

The auto emergency braking consistently brakes for no apparent reason while using adaptive cruise control or autopilot. The Tesla Model 3 will consistently slow and brake while passing a semi or larger vehicle while myself and the vehicle I am passing are both within our lanes with no abnormalities. This "phantom braking" is the worst on a two way (one lane each direction) highway at night. It was so bad I could not use and trust the autopilot/cruise system because it was more unsafe to use it than to just turn if off. I feared that I would get rear ended or it could aggressively brake in a corner causing me to loose traction. I also had the vehicle brake with no vehicle approaching and no one behind. It just randomly applied the brakes and the collision warning went off. Literally nothing in front or behind me on a two lane highway (one lane in each direction). My cameras were clean

The contact owns a 2022 Tesla Model 3. The contact stated while driving 60 MPH with the cruise control activated, the vehicle stopped independently and without warning. An unknown dealer was contacted and made aware of the failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 1,000.

Mileage: 1,000

While driving with either cruise control or autopilot my car constantly brakes or “phantom brakes” for no apparent reason or brakes VERY hard when semis are approaching in opposite direction. This happens mainly on one lane country roads. On the freeway it’s less but it has braked for absolutely NO reason ( no cars around) at least a few times per month. My wife will not use cruise control due to this happening so often. I drive it most of the time and since I use cruise control or autopilot it “phantom brakes” every single day.

Feb 14, 2022: 5:55 p.m. on cruise aka AP. Aggressive/phantom braked 31 mph to 0 in 1 sec heading west on Wildhorse Parkway between Caspian Spring and Buckskin Bend San Antonio 78254 with a car behind 3 lengths. 30 sec later control panel displays cruise control will not brake. Same day 724 p.m. set cruise to 39 mph braked very hard travelling northwest on Shaenfield Rd about 200 yards from McDonalds 8107 TX-Loop 1604 San Antonio TX 78254. Complete 17 sec video comments about cruise control brakes available. Unable to attach video. Feb 17 cruise or AP used twice at 2:00 to 3:00 p.m. and 9:00 to 9:30 p.m. No engagements with hard braking. Since ownership Feb 4-17 side repeater and back cameras indicate false distance of oncoming traffic making for unsafe condition and issue was raised with Tesla tech and he informed me since cameras are static, nothing they could do. Additionally, Feb 14, turn signal camera for blind spot detection did not come on during right turn signal but came on for left turn signal.

The contact owns a 2022 Tesla Model 3. The contact stated while driving approximately 55 MPH and using the automatic cruise control, the vehicle inadvertently slowed down with a larger vehicle approaching from the opposite lane. The contact stated no warning light was illuminated however, a warning alarm bell chimed and the vehicle decelerated to 20 MPH. The contact reported that after the larger vehicle went by, the vehicle resumed the pre-set cruising speed. The vehicle was not taken to the local dealer; however, several scheduled appointments with the techs at the dealer had been canceled. The vehicle was not repaired. The manufacturer had been informed of the failure and the contact was informed that the failure was a software issue known as Phantom Braking. The contact stated that the manufacturer recommended continued use of the cruise control in order to gather more data on the cause of the failure. The contact was concerned about the risk of a crash while using the feature. The failure mileage was approximately 200.

While using cruise control, the car will very frequently hesitate and slows down a few miles per hour, but in addition, the car will suddenly, very forcefully try to stop. This happens more often after dark and with on-coming vehicles, especially trucks. There is no warning sound or chime as will happen if there is actually an obstacle. The vehicle simply tries to stop and I feel that I would have ended up into the windshield if not restrained. The touch pad also shows no warning notice as it does if there is an obstacle such as a car in the way. This has happened with other cars behind me, but not anymore as I no longer use cruise control, especially if there is any traffic at all. The vehicle has yet to be seen in any Tesla service center due to difficulty getting an appointment. On-line searches reveal that this is a problem for others as well. The vehicle has not been inspected by anyone else. This issue appeared very shortly after picking the care up on 12/31/21. I had a 2019 Tesla Model 3 which never did this.

I was traveling northbound on a two lane highway with a speed limit of 55mph. I was traveling 60mph with Tesla autopilot to include autosteer engaged, it was light outside and partly cloudy. A tractor trailer approached traveling southbound in the opposite direction, my vehicle immediately slammed on the brakes, dropped speed to under 25mph, and the forward collision warning chimes and alerts on the screen started. It should be noted I was well within my lane of travel going northbound; the tractor trailer was also well within its lane traveling southbound. At no point did my vehicle or the tractor trailer veer towards each other, and at no point was there ever a chance of our vehicles colliding. This happened a total of two times, both times the circumstances were identical involving tractor trailers.

While driving on the interstate with the adaptive cruise control engaged I’ve now had four incidents where I’ve had to over-ride the system because the car mysteriously slammed on the brakes attempting to stop the car when no threats were apparent. These were frightening and dangerous events. I’ve had several cars with adaptive cruise and never experienced this type of un-provoked emergency braking. The for situations were as follows: 1) The road gently curving to the right while I was in the second to far left lane and there was a concrete barrier left of the far left lane divining the opposing lanes. The car apparently mistook the barrier as a threat because it slammed on the brakes without warning. I override the system to avoid a collision from behind. 2) Driving down a three lane road in the center lane when a car entered the road into the right lane and was still going much slower than the center lane. My car slammed on the brakes despite the other car never coming close to entering my path or lane. 3) two instances of the car emergency braking on a two lane road because it apparently mistook oncoming traffic in the opposing lane as a threat. Again had to override to avoid being rear ended. This adaptive cruise system is too dangerous to use as I cannot trust it to not brake hard and unexpectedly.

My mother was driving my brand new 2022 M3P from Garfield, AR, to S. Coffeyville, KS, on a two lane highway when we experienced a major AEB event while in cruise control (if not w/ autosteer engaged). On the way there and back to Garfield, we must have experienced 5-10 AEB events where the traffic aware cruise control thought that the hard shadows from trucks were actually objects in our lane. This is a horrible and dangerous design flaw. Why are we not allowed to go back to dumb cruise control like we used to have where it doesn't cause an accident risk due to the possibility of a rear impact from another vehicle? In one of these events there was a truck behind us, and my 70-year-old mother had no clue how to protect us from being rear ended. We desperately need an option to disable TACC at the very least. I don't care about what laws may be in place for these systems, until it is perfect, we should be allowed to have full control over our vehicle without unpredictable events occurring. Trying to teach a 70-year-old how to drive differently isn't a proper solution when they've driven vehicles their entire lives that let them do what they want. Demand that Tesla allow permanent disablement of these systems, not just turning off AEB every time you get in the car! And I'm not convinced that AEB is even related to TACC braking. Regardless, fix it!

Car randomly auto braked at night while on cruise control (45 mph). Car turning across traffic was roughly 200 feet away and well out of potential collision range. Also, car won't auto break when there is an actual obstacle in front. Could drive the car into a wall (believe me, I've verified this).

This is my third report for the same phantom braking issue I drove approximately 250 miles today and had three episodes one while passing a 18 wheeler he was on the right and fully in his own lane it braked forcefully. And two episodes with no objects or any explanations why it applied the brakes hard while traveling at 78 mph once with a car following witch caused me great concern. Side note I gave up using it on two lane undivided roads any oncoming large truck or RV triggers braking.

On my daily commute to work on the interstate while in cruise control the car will slam on the brakes fro no apparent reason. This abruptly takes my car from 70 mph to 40. Happens multiple times in cruise control every day.

I have experienced multiple situations where my 2022 Tesla Model 3 has issues with the automatic emergency braking feature, which causes the car to slam on the brakes unnecessarily while operating in the autopilot mode. Generally, I've seen this the most on 2 lane roads, especially when large vehicles (semi trucks, etc) are in the opposing lane. In some cases, the car will brake when there are no cars in the opposing lane. My concern is that the cars traveling behind me may not have the reaction time to brake, due to not expecting my car to brake in front of them.

This has happened on a couple of different occasions but the one thing that has been the same is it has happened while utilizing the adaptive cruise control system. These incidents come out of nowhere and can be dangerous and cause an accident luckily we have not had that misfortune. While driving on the highway with adaptive cruise control enabled, the vehicle has suddenly and without warning activated the emergency braking. The first time this occurred the assumption was that it must have picked up something on the road because it only lasted for a brief moment, it slowed down the vehicle by 10-15 mph. Throughout this trip, adaptive cruise control was used and it didn't occur in that manner again. What is more alarming are the next couple of incidents which abruptly slowed the vehicle down by 30-35 mph this was very unsettling, luckily no one was behind the vehicle at the time of these incidents. The adaptive cruise control has not been utilized since the last incident which occurred the third weekend of January 2022. The severity and abruptness that the vehicle slowed and I must mention without warning can potentially cause a fatal car accident, especially while driving on the highway. The vehicle has not been inspected or serviced since the incidents and as long as adaptive cruise control is not used there have been no further incidents of this nature.

Multiple times while driving using adaptive cruise control while approaching a semi(both oncoming and overtaking) the car will slam on the brakes(phantom braking).

On a four-lane divided highway and again on a two-lane road my Tesla 3 long range AWD phantom braked for no apparent reason several times over a 145 mile trip while on cruise control and/or on auto pilot . On the two-lane portion of the trip I assumed the braking occurred because of shadows on the road. On the four-lane highway it braked for no reason. If someone had been closely following me, I am sure a serious collision would have occurred. I will not use either cruise control or autopilot until a fix is made. This Tesla on cruise control makes for a dangerous driving situation.

Freeway driving on a clear day in low traffic on a straight road using Tesla’s TACC adaptive cruise control the car abruptly slowed from 73 mph to @ 50 mph with no vehicle in front of my car. This was a very brief deceleration. The braking released after @ two seconds and the car returned to the set max speed (73 mph).

While using adaptive cruise control or the autopilot systems, the car will unexpectedly brake very hard (dropping speed anywhere from 5-20 mph). This can cause a safety issue due to other cars behind that aren’t prepared for a car to randomly hit the brakes and drop up to 20mph quickly. The problem is easily reproducible by using the systems while driving anywhere. Complaints and requests to the manufacturer have gone unfixed and brushed off as not a concern. This happens every single time I use cruise control, not just the date I had to select for the incident.

When driving on two lane highways and using the "autopilot" cruise control, the car will occasionally panic brake for no valid reason. This occurs almost every time an oncoming semi passes in the oncoming lane as well as going over bridges with raised sides or when there is crack seal on the road that is slightly more reflective. This has happened several times when crossing a bridge with cars following closely, almost causing several accidents. Tesla service was contacted immediately and I was told that it was a "software issue" and that there was nothing I could do. I tried disabling emergency braking in the car interface however it had no effect on the issue.

I would like to add my voice to those complaining about the phantom braking problem in recentlly built Teslas. On more than one occasion, the car has slammed on the brakes, in broad daylight with good visibility, FOR NO GOOD REASON. At the very least, Tesla should be compelled to add plain-vanilla cruise control that permits the driver to switch off any traffic-aware assistance features. This problem is ongoing and occurs nearly every time I attempt to use the traffic-aware cruise control. The problem makes this feature too dangerous to use.

While using “Traffic-Aware Cruise Control” the car regularly sounds an alert and breaks rapidly in preparation for a forward collision despite no such danger existing. Most often this occurs on a two-lane highway when a large van or semi-truck is traveling in the opposite direction; in its own lane, nonetheless. This feature is marked as “beta” but there is no standard cruise control option. This issue can be easily reproduced and happens multiple times on any given day when said circumstances exist. Tesla service advisors have told me the only fix is to not use the feature. I am scared the sudden breaking may cause whiplash, a rear end collision, or other danger presented by sudden unnecessary breaking. When using the additional Autopilot feature, “Autosteer,” the incidents seem to happen even more frequently and invoke a slight swerve right - away from the vehicle in question. This could make it even harder to recover from the phantom breaking event.

This vehicle has frequent issues with phantom braking whenever cruise control is engaged. The brakes are suddenly applied automatically and sometimes severely. This occurs dozens of times on long drives and I purchased the car new 6 weeks ago. I have reported it to Tesla and was told this is a “known software characteristic”. I brought it in for service and provided date and time stamps for dozens of occurrences. The service manager confirmed with me that this is a known issue that Tesla is looking into and that even her own Tesla has this problem regularly. This is clearly a safety issue and makes me feel unsafe to drive this car, which is especially concerning since one of the biggest selling points for me was its rating as the safest car on the road.

Phantom braking issue. Usually occurs on two lane roads, sometimes there is a vehicle in the opposite lane, other times there is nothing in front of the vehicle in either lane. I have reported to Tesla, they say they’re aware but have no solution. I have kept a log of when it happens since the first time I reported it to Tesla and was told there is no solution. I commute 128 miles a day and the below log shows it happens on daily basis multiple times a day. 1/5/2022 5:32pm 1/5/2022 5:35pm (multiple times) cruise set at 65, speed got down to 45 1/5/2022 6:30pm 1/6/2023 5:59pm 1/6/2023 6:01 1/6/2022 6:33pm 1/6/2022 6:34pm 1/6/2022 6:37pm 1/10/2022 6:37am 1/10/2022 5:11pm 1/12/2021 7am 1/12/2022 5:49pm 1/12/2022 5:50pm 1/12/2022 5:53pm 1/12/2022 5:55pm 1/13/2022 6:13am 1/13/2022 6:15am 1/13/2022 6:16am 1/13/2022 6:18am 1/13/2022 6:21am 1/13/2022 6:09pm 55 to 38 1/13/2022 6:11 pm 55 to 44 1/13/2022 6:13 pm 55 to 46 1/13/2022 6:14 pm 55 to 42 1/18/2022 6:09 am 55 to 41 1/18/2022 5:39 pm 1/18/2022 5:43 pm 1/18/2022 5:44 would not resume speed on cruise control 1/18/2022 6:17 55 to 42 mph 1/18/2022 6:18 55 to 44 1/19/2022 6:14 55 to 37 1/19/2022 6:47am 70 to 32 1/20/2022 6:10am 55 to 47 x2 1/24/2022 7:32pm 70 to 53 1/26/2022 6:33am 1/26/2022 6:07pm 55 to 45 1/26/2022 6:06 55 to 48 1/26/2022 6:15 55 to 49 1/27/2022 6:48 55 to 47 1/27/2022 6:50 60 to 43

on 2-3-2022 on a 200-mile day trip I had two false braking events one while passing a large truck on a divided AZ Hwy 260 and one for no notable reason what's so ever on the same Hwy. I do not have FSD just autopilot this is my second compliant to NHTSA thank you. Mike

Twice now the car abruptly slowed down from about 75 to 50 in the left lane of the highway with nothing in front or next to my car. Falsely thought there was something in front of the vehicle and it quickly decelerated. Oddly happened both times in the same spot on the highway. Seems to be an issue with that area on how it looks in the "Tesla Vision" software. Both times almost caused an accident with the car behind me.

Random "phantom braking" while on cruise control. Unexpected and significant braking. On icy or wet roads, this could cause a departure from the vehicle path and road. It happens often enough that I'm rarely using it anymore. And fora feature that is supposed to be a safety feature (reducing driver fatigue, backup to emergency braking, safe following etc.) this is very bad.

Driving on a two lane rural road with a 55mph speed limit, I had traffic aware cruise control engaged with the speed set to 55 mph. A truck crested a hill coming the opposite direction, fully within their lane, and the car engaged the emergency breaking system. Fortunately, no one was behind me at the time as this could have resulted in me being rear-ended.

Cruise control is completely unusable on two lane roads. Automatic braking ensues every single time a car is in the opposite lane. Sometimes it only slows 5-10 mph but other times the car gives the warning for an imminent collision and tries to brake to zero. This is exceedingly dangerous on the highway when other cars are behind me. It generally functions fairly well on the interstate but it does happen occasionally there as well.

When using cruise control (TACC) with or without using lane centering (Autosteer), my vehicle will often brake suddenly (and harshly) for no reason at all. It's worse on undivided highways (with no median). I've noticed the phantom braking occurs most often when an oncoming tall vehicle (18-wheeler, RV/motor home) approaches, or I approach an underpass, or I approach a large shadow on the road (from a building or large tree). During a 90-mile trip last weekend, my car phantom braked almost a dozen times, sometimes severely. Fortunately, no one was following close to me. I feel this is a safety hazard and should be fixed.

Traffic aware cruise control is dangerous to use. Automatically slams on brakes on 2 lane roads with large vehicles in oncoming lane. Brakes at the top of any sort of hill, brakes for shadows of overpasses on the highway. System is dangerous and has caused several situations where I would have been rear ended on 2 lane roads and larger highways. Recent road trip had almost a dozen phantom braking events on a one hour drive on a straight 2 lane road during the day.

The TACC (traffic aware cruise control) applies sudden, hard braking especially on two lane roads and almost always when meeting a large truck (semi-tractor trailer). This is commonly referred to as “Phantom Braking“. Drivers should be allowed to disable automatic braking while using cruise control on two lane roads. It is very dangerous in that it may cause a rear end collision. The cruise control as currently implemented in Teslas is unusable and without a doubt a safety hazard. I have experienced phantom braking events every time I have used cruise control on a two lane road. It will hard brake 9 out of 10 times it meets a large truck and sometimes when meeting small cars.

I have experienced phantom braking events every time I have used cruise control on a two lane road. It will hard brake 9 out of 10 times it meets a large truck and sometimes when meeting small cars.

On February 2, 2022 at approximately 8:00 a.m., MST, I was driving north at 50 mph on a stretch of two-lane highway with moderate traffic. Adaptive cruise control was engaged. A large truck was approaching, traveling in the opposite direction. Suddenly, and without warning, my vehicle’s brakes were applied, without my involvement, slowing my vehicle to approximately 20 mph and causing the driver of a vehicle traveling behind me to slam on its brakes to avoid a rear-end collision. No collision occurred and no one was injured. It could have been a lot worse, but this problem needs to be identified and fixed.

Our Tesla is experiencing a Phantom Braking that appears to be a known issue. We drove the car from eastern KS to western CO and experienced multiple occurrences (more that 10) of unexpected braking while using either the adaptive cruise control or the auto pilot feature. The car would dramatically slow from 75 to perhaps 65 and then accelerate back to 75. My wife also takes the car to work on a 20 mile commute and she has also experienced this. I have not discussed this with Tesla Service yet, but have read many posts about this and that we should report. So....here it is!

Vehicle applies 100% braking sporadically when traveling at highway speeds on cruise control, causing loss of control and risk to vehicles behind it. It seems that the vehicle’s forward sensors mistakenly interpret an imminent collision and apply full braking force, without any potential collision risk present. This happens in all scenarios, single to multiple lane highways, dense traffic to no traffic. This is commonly referred to as “phantom braking”.

I received my 2022 Tesla Dec. 3, 2021. I have experienced approx. 100 phantom braking incidents in roughy 3,000 mi. Driving. The system causes a loud alert and extreme braking which is extremely concerning while driving. This has happened in all conditions (daytime sunny, cloudy, night, etc.). Several camera warnings though I have cleaned them and alerts still happen. It happens on 2-lane roads more often than multi-lane highway. Happens at residential and highway speeds. The extreme braking could easily cause rear end collisions if traffic were close. As a driver the abrupt alerts and braking could cause driver errors. This is a “safety” feature which is extremely disruptive to drivers is in fact a safety issue in my opinion. The data below is the most recent incident and it happened 3-5 times in a 300 mile drive. Tesla Service cancelled an appointment to look at my car. In a chat exchange they deflected it as environmental, driver error, dirty cameras, etc.

Issue is consistent on 2 way lane roads but sometimes occurs on Highway roads going in the same direction. Whenever I travel with autopilot or cruise control if there is a semi-truck on the opposite lane driving towards me the car will slam on the brakes for no reason. This has also happened a few times on the highway when passing a semi-truck on the same flow of traffic as myself. This has not only terrified myself but also my family and other passengers. It makes this feature almost unusable.

While traveling on a two lane highway while using Traffic Assist Cruise Control I have had several collision alarms and emergency braking situations that were severe enough to cause my unprepared wife to say that she could have gotten whiplash. Luckily there was no one following us closely enough to cause a rear end collision. I have notified Tesla and they said that since it is actually in beta that the system is working properly. With the software capabilities that Tesla has I feel that they should provide a workable basic cruise control that can be used.

When driving with cruise control on the car will suddenly apply brakes if it detects a car coming at me from the opposite lane. This is a safety hazard as the cars behind me would have no idea I would be stopping and poses a serious rear end threat.

On a recent road trip while driving on highway 70 in CO and UT at speeds of around 70mph with Autopilot or Cruise Control engaged, the car phantom braked multiple times in response to nonexistent hazards on the road. Fortunately there were no cars nearby in both instances, as I am positive we would have gotten rear-ended in both situations (the car braked to around 40mph). These were both really scary scenarios and undermined my trust in those systems in the car, I have been hesitant to use them since

Autopilot and Traffic Aware Cruise Control systems are basically unusable on two lane highways. Almost every vehicle that passes on the opposite side of the road triggers an alarm, disengages Autopilot/TACC, and results in an abrupt, jarring deceleration. This occurred 10 times in a 160 mile trip, but would have happened many more times if I had not given up trying to use either system. Holding my foot on the accelerator for such a long drive was inconvenient, and the repeated sudden slow downs resulted in a strained, tired neck. It seems unethical for a $60,000 vehicle to lack basic cruise control capabilities.

The autopilot feature which keeps the car in it's lane and speeds up or brakes the vehicle based on its surroundings is not functioning properly. It slams on the brakes whenever a semi-truck or large vehicle is driving in the opposite lane on a two-lane road. Especially if there is a bend in the road. It thinks that a forward collision is going to take place.

Every once in a while (once per 100-200 miles) I experience "phantom braking" when using Adaptive Cruise Control with Autosteering (not sure if Autosteering matters – I always use ACC with Autosteering together, so hard to tell). That is when ACC decides to quickly reduce speed significantly for no apparent reason (no cars or other obstacles in front). It could be dangerous as it could lead the car behind me to crash into me.

Phantom braking, almost caused a car to rear end me. This was on a straight two lane road a tractor trailer was coming the other way. This has also happened on a right hand curve with smaller auto where the software thinks I'm going to run into the car even though I'm turning right into the curve. Very dangerous. Same thing happens with the forward collision warning.

When the ADAS is active, during normal driving on a two-lane highway, where there is never any question of an obstruction in front of the car, the car unexpectedly and violently brakes; often the collision warning alarm sounds. This usually happens when the car meets traffic in the oncoming lane, but sometimes there's nothing else at all on the road. This is a new car (since January) and it has happened ever since I first used the ADAS. For example, last night, on a trip of about 50 miles it happened at least thirty times, nearly every time I met an oncoming vehicle of any size. Service personnel tell me this is normal behavior and they cannot do anything about it! The system is supposed to have switches to turn off the collision warming and braking so that it can be used as a normal cruise control, but setting the switches to off has no effect. This behavior is not only extremely annoying but also distracting for the driver and potentially hazardous when an inattentive driver is following closely.

The car brakes SEVERELY on two lane highways when passing another car. Mainly occurs when passing semi trucks. It is going to get someone rear ended if this is not fixed. The cruise control is not usable.

When i drive on highway, it out blue slam brake several time i am not sure what trigger it. it was out blue from 70 mph to 50-60mph. i don't see anything around car to trigger phantom braking or brake. also on one lane highway, when semi truck or some car/trucks pass by me it slam really hard few time from 60 mph to 30 mph instant, some car almost hit my rear because of instant slam brake. I had to brake quick to undo it. it happen on cruise control only, also happen during auto pilot. the road was fine, other vechile wasn't going toward me.

Sunday, January 2nd, on the way back from Vegas back to Sacramento, on the highway with Lane assist driving, the car suddenly braked going from 70+ miles to almost a complete halt. I was able to steer it into the oncoming lane to avoid the pick up truck from hitting us from behind. The braking system again slowed the car down significantly a few more times on this trip and wee have not used this feature since. Car was bought on December 26th and we are fairly new owners of a Tesla.

My vehicle brakes suddenly when auto pilot is actuated for no reason. Often times, this is a very abrupt brake. This happens many times every time driven

While driving on an undivided highway at night using either traffic aware cruise control or autosteer, about every minute the car would aggressively decelerate up to 15mph. Every time a car would pass in the other direction, the deceleration would be abrupt and would slow to ~10mph below the speed limit. This occurred at least 3 times within a ~7 minute window. The road was straight, unlit, with a 50mph speed limit, and was sufficiently wide to safely pass oncoming cars. Random deceleration with no oncoming cars would be less severe but frequent. I contacted Tesla about this and they confirmed these occurrences but stated it was in response to a curve in the road or a vehicle being detected. They claimed the system performed appropriately. Despite being alert, these decelerations are startling in the absence of visible explanation to the driver. If I was being tailgated, a rear end collision would have been highly probable. I owned a 2018 Tesla Model 3 and have driven the same road at night and never experienced this.

The vehicle is having a very serious problem with phantom braking whenever the cruise control is engaged. The problem occurs randomly regardless of road conditions or traffic conditions. While driving at any speed with cruise control engaged the car with randomly brake hard and sound an alert. The road has always been clear of obstructions and debris. It will also engage braking abruptly when a large truck or bus is coming towards me in the opposite lane on a two lane road. At first I thought it was an anomaly. But now after 3400 miles of ownership I fear for my safety while driving because of the conduction. To the point that I have stopped using the cruise control and auto pilot because of the issue. Considering that autopilot was one of the main reasons for me to purchase the vehicle, it seems like I have been missled and sold a vehicle that is unsafe for public roads.

On multiple occasions, my car has slammed on the brakes while using adaptive cruise control when nothing is in front of my car. It’s concerning because drivers behind me have almost rear-ended me and have gotten road rage at me because they think that I am brake checking them.

The car on a day basis exhibits random braking incidents when utilizing traffic aware cruise control (TACC). These have happened since the car was new (now has over 2,500mi) and can range from mild to severe. All of them happen without an obstacle ahead. Some times it seems the vehicle reacts to shadows from trees or larger structures, other times there's no obvious reason behind the reaction. The braking happens both on interstate highways as well as county two and four lane roads, and isn't related to elevation change or curves (happens straight and level). Several of these instances have been close to causing accidents due to traffic behind me getting caught off guard, which is usually followed by some sort of road-rage-like reaction. I no longer use the system when there's any traffic behind me due to the fear of getting rear-ended. I have recalibrated the cameras 3 times to no avail.

Driving on two lane road with oncoming semi truck traffic causes adaptive cruise control to abruptly apply brakes. As this has happened numerous times, I called Tesla who advised me to not use adaptive cruise control. I do most of my driving on two lane roads over long distances to shop or see a doctor, etc. Not having ANY cruise control is better than causing an accident, but why cant Tesla program a simple non-adaptive cruise control?

On 1/24/22: 9:11 am eastbound Redden Road east of Bridgeville, DE. This is flat terrain with mostly open fields on east side of the road. On a straight Regular 2 lane road, center yellow strips and white edging. West bound truck triggered braking and swerve to left. 9:14 Another truck and same circumstances further east and same result. Turned off steering assist and cruise control. 10:42 westbound on Redden Road roughly same area. Truck eastbound. Slight braking 150 yards in front of me then brakes slammed on while passing each other. Braking reduced speed by 10 mph or more and swerve to right. Hard braking and a swerve to the right for no reason. Anyone behind me would have hit me. Basically I have to make sure road behind me is completely clear before turning cruise control or auto steer on! Anyone within 5 car lengths would hit me. Not safe. Can they remotely download these events from the car? TESLA VIRTUAL DIAGNOSTICS Reviewed the logs and confirmed the phantom braking and confirmed it was due to not having a forward facing radar. System overly sensitive to err on the side of caution. They hope to fix it eventually via software updates. In my opinion, it isn't safe and should be de activated and money refunded.

Phantom braking in city and highway with no obstacle in vehicle path. Sudden and strong emergency braking enough to cause a rear end collision if being followed. Very scarry in one 700 mile road trip we had 11 such occurrences . Thank you for your help. Mike

Dangerous or phantom braking of vehicle on two lane road at highway speed.

I took delivery of my Tesla Model 3 in mid December and have have driven approximately 2,000 miles, almost all highway commute miles. I have had horrible experiences with the Autopilot cruise control slamming on the brakes for no apparent reason. Nothing in front of the vehicle, sometimes nothing around the vehicle at all. Behavior is sometimes a quick deceleration of 10 mph or so; however, in some cases FULL brake is applied, coupled with an audible collision warming. Again, these things are happening with NOTHING present in front of my vehicle, and sometimes with nothing around me at all. During my daily commutes, I experience, on average, 5 to 10 instances of this unsafe slowing/stopping procedure. In one instance, the vehicle decelerated from 64mph down to 37mph, for no reason, with a line of other vehicles following me. We narrowly avoided a multi-vehicle collision, caused by a completely unnecessary braking application. Needless to say, as the line of cars passed me, each of the other drivers were very unhappy with me, probably assuming I had “brake checked” them, considering there was no one in front of me and no reason to quickly decelerate from 64mph to 37mph. Had they been following closer or not paying attention we surely would have all be involved in a collision. I reported the issue to Tesla and was told “the vehicle detected a ghost object…This is currently a normal characteristic of autopilot…” There is no other “normal” cruise control feature on the vehicle, it’s either use Autopilot and risk being involved in a collision, or drive the vehicle myself (which defeats the purpose of purchasing the vehicle for commute reasons). Very unhappy that Tesla did not offer to even look into my issue, considering it’s not an occasional problem, it occurs several times per commute trip,

@ 1:36pm, while driving on US State Route 50, in IL, I had adaptative cruise control engaged, but autosteer unengaged. While a semi-truck was passing in the opposite incoming lane, the forward collision warning system falsely activated with warning chimes, and applied full braking. There is another vehicle that was following me, which had to take evasive maneuvers to avoid an accident. This was reported to Tesla Motors for which they responded that the vehicle log shows no hardware errors, and a software bug report need to be created when this happens. This happens daily, more than six to eight times a day, and is very dangerous.

As widely reported by Tesla owners, I have also experienced issues with the TACC - traffic aware cruise control - feature of this vehicle. I have owned it for almost 2 weeks and in that time on both highways and city streets the 'cruise control' feature has initiated braking for no reason. The system is supposed to be 'traffic' aware however in these instances there was no vehicle in front of me in any position to cause a braking event. This type of erratic behavior could easily cause an accident (being rear ended). This is happening when the 'autopilot' feature is not engaged, but rather just using the only available cruise control feature the vehicle provides: TACC. It seems as though the software is interpreting shadows, changes in painted line/lane markings, or other environmental stimuli as 'traffic' and reacting, but that's just a guess. All I know is that it is very annoying at a minimum and potentially quite dangerous!

Traffic-aware cruise control unexpectedly decelerated and/or activated collision warnings and automatic braking approximately 20 times during a 300 mile, 5 hour drive. All incidents occurred on undivided highways and state roads. This unexpected braking reduces speed by 10 to 30 miles per hour on 60 mile per hour roads. This braking issue greatly increases risk of accident, specifically if another vehicle was following too closely. Braking events occur sporadically, usually attributed to large vehicles driving well within the opposite lane. Some events happened for no reason. Occurrence of unexpected braking is higher at night. This vehicle has been inspected by Tesla in the past due to this same issue and the cruise control and autopilot system was confirmed by technicians to by working properly. The ability to disable adaptive cruise control to standard “dumb” cruise control may solve this issue. This issue instills no confidence in Tesla’s so-called “full self-driving computer” and has me avoiding using these features for my safety, as well as other drivers’ safety. This vehicle is available for inspection upon request. Dashcam video is available on request.

The cruise control and 'autopilot' features will panic brake when oncoming traffic passes car. It is more common on two lane highways. There are no overrides and the issue occurs in all modes of cruise control. Through research on forums, this is an issue with all Tesla vehicles model year 2017+ The car brakes hard, enough to lock passenger seatbelts. Sudden hard braking with no reason can cause a rear end collision or loss of traction in inclement weather. I have notified the manufacturer of the issue, their suggestion is to recalibrate the cameras and reset the on board computer. Neither has solved the issue No warning lamps, no symptoms.

Driving on a two lane road with no other cars in front of or behind me the car would randomly brake at different levels and in the most recent incidence slammed on the brakes. This issue is noted by many other drives online as Phantom Braking and Tesla will not repair it as they claim it is a software related issue but not deemed as dangerous or a real issue to be concerned with. Tesla will not service the vehicle and closed my tickets without further response.

VERY AGGRESSIVE phantom braking on two lane highways and at night with oncoming headlights. Car will reduce speed by 30mph or more in seconds. This is a new car, a month old. Tesla says cruise is part of autopilot, but we turn autopilot off and just use cruise and it still does it very often. It is extremely unsafe. The internet is full of similar complaints. We need NHSTB to pressure Tesla to fix this. It is a major safety hazard.

Using the cruise control frequently results in the autopilot system abruptly applying the brakes, risking a rear-end collision. This happens even when no car is in the lane in front of me. The cruise control is integrated with the autopilot system, which apparently is mistaking oncoming traffic with a car in my lane. The cruise control is integrated with autopilot and its traffic-awareness feature. The cruise control cannot be disconnected from autopilot, and the following distance feature cannot be turned off as with other makes of cars. I reported the issue to Tesla service and was told other drivers have reported the issue, yet the issue has not been brought to the attention of all Model 3 owners.

Three incidents within 5 minutes of what Tesla owners call "phantom braking" whenever the car has cruise control on. For no predictable reason and no warning the car brakes suddenly and forcefully - could be shadows, reflected lights, oncoming traffic, who knows. It is a scary phenomenon and caused me to get in very dangerous situations - almost got rear ended at 60 mph. This is after owning the car for only 10 days. Called Tesla and they had no answer except to say that the car "will learn."

Car brakes randomly when using traffic aware cruise control. Dozens of events every hour of driving, some of which caused the car to brake to the point of losing traction.

When on adaptive cruise control, random and sometimes severe automatic braking incidents occur when no obstacles exist in front of the car. It is as if the car is getting confused as towards what is ahead, and frequently applies the brakes as if it was going to crash into something. This is always unexpected, and requires driver intervention to correct/override.

**Im well aware that Tesla's AutoPilot system is not autonomous** There is no 'dumb' cruise control option on Tesla Vehicles, only Traffic-aware-cruise-control (TACC). TACC is unusable, and quite frankly dangerous, on any single-lane divided road. Anytime a large vehicle, such as a semi or box truck, passes by in the opposite lane, my car abruptly and aggressively brakes while TACC is engaged. This poses a danger to myself and others behind me. Im filing this complaint in hopes that it will coerce Tesla to address this issue faster.

On at least five occasions since purchasing this car new on 12/07/21, the car, while on Autopilot (non-FSD), has suddenly and unexpectedly braked on clear roads. On each occasion, there were no vehicles in front of me nor any objects visible on or near the roadway. On two occasions, a car following me nearly collided with my car. All the incidents occurred AFTER camera calibration was completed. The car has 143 miles at this writing.

While driving on freeway at 75mph the car for unknown reasons applied braking and steering and brought the car down to 45mph before I could disengage the autopilot function. This has happened multiple times with just cruise control and both cruise control/steering. All instances happened for unknown reasons, sometimes on a 2 lane highway or multiple lane freeway with nobody around except behind me. I had a very difficult time controlling the car when this happens and the vehicle behind me had to slam on their brakes and swerve around me. This is a very scary and extremely dangerous issue. Issue has been reported to Tesla and awaiting fix.

While using TACC on a 2 lane road the system mistook a vehicle approaching in the opposing lane as a threat and braked hard. This could have easily caused a collision had someone been following closely.

The contact owns a 2022 Tesla Model 3. The contact stated that while driving at various speeds with the cruise control activated, the vehicle would independently brake with the Forward Collision Avoidance warning chime being audible. The contact stated that the failure would occur when oncoming large vehicles or as another vehicle in the opposite lane would drive past the vehicle. The contact called a service center where an appointment was made; however, the contact received an email that informed him that the appointment was cancelled. The contact was informed that an internal diagnostic was performed and that no defect was discovered. He was informed that over time the vehicle would adapt and improve its performance over time. The contact stated that the failure had persisted, and no improvement had been made. The vehicle had yet to be repaired. The failure mileage was 16. When travelling at 62mph with cruise control engaged, if a semi is oncoming in the other lane, the car will brake suddenly and slow by 30 plus mph in seconds.

Mileage: 16

Forward collision avoidance system triggered 4 separate times in a 70 minute/60 mile drive on a stretch of highway and rural roads. The highway consists of 40 miles of divided and undivided highway, with up to 2 lanes per side. Occasionally, the undivided section has center turning lanes. Junctions and turnoffs are common. 3 incidents of forward collision detection automatic braking were triggered by semi trucks in the oncoming lanes on 1 lane per side undivided highway. The vehicle automatically applied the brakes, taking the vehicle from roughly 60mph to 30mph quickly during each instance. The trucks were not particularly close, nor were they appearing to leave their lane into mine. The 4th automatic braking incident occurred seemingly randomly on a rural, undivided 1 lane per side state road. All of these had the potential to cause an accident if I were being closely followed. All incidents occurred using the Autopilot cruise control feature. The auto steer lane keeping feature was activated for at least 1 of the 1st 3 events, but I do not recall which. In all of these instances, the vehicle did not perform any other evasive maneuvers. The 1st, 2nd, and 4th incidents were completely unexpected. The 3rd occurred during a particularly narrow, curvy section of undivided highway, which we were actively anticipating. Due to a configuration issue, the onboard dashcam was not functioning during these events and no video of these events was recorded. This vehicle is expected to go into the service center late December for this and other trim quality issues. Customer service indicated interest in these events and advised me to file bug reports when these occur. For issues with lane keeping, the autopilot auto steer feature regularly under-steered during most curves (narrow canyon driving) and often strayed closer to the lanes to the left of me than I would under my control.
