2021 TESLA MODEL S Forward Collision Avoidance Problems

On October 17, 2025, while using Full Self-Driving (FSD) mode on my 2021 Tesla Model S Plaid, the car failed to stop at two red lights within a three-hour period. In each case, the car attempted to drive through the intersection even though the signal was solid red. I intervened manually and applied the brakes to prevent a potential collision. There were no prior warnings or alerts, and I have not modified the vehicle. This behavior endangers my safety and the safety of others. I am willing to provide the vehicle and any available data logs for inspection if requested.

GETTING WARNING ONDASH THAT SAYS "Adaptive ride control unavailable. Vehicle speed limited - Proceed with caution". On the internet many reports are noted of the same problem w Tesla vehicles, especially Model S cars. These have occurred soon after to taking delivery of after 20-30 K miles. Mine occurred at about 31,000 miles in my Model S 2021. Tesla says the need "diagnostics done first " at $275 and then the fix for another $300. This does not seem right.

I engaged Tesla's Autopark to park my car in my usual spot. The car kept going after reaching the back of the parking space, crashing into a pole located around one foot behind the parking spot. The time between when it should have braked and the post was of such short duration that I had no time to apply the brakes and prevent the accident. The car lacks both radar and lidar, either of which would have detected the post. Instead it relies on a single video camera. What made this parking different from previous safe parking attempt in the same space was that the car was perfectly lined up. That meant that the camera could not make use of parallax to enable the AI to notice that the post was moving against the background and must, therefore by close behind instead of 40 feet away. For Tesla Autopark to function safely, it needs to "know" how far back possible obstructions are. It could do so by never backing up with perfect alignment. Instead, the car should move enough from side to side to generate enough parallax effect for it to be able to determine if it is about the crash. The service manager who called to tell me that Tesla decided the accident was my fault absolutely refused to even hear my opinion on what Tesla could do to prevent such accidents in the future. He told me he had be instructed to deliver Tesla's disclaimer and to not listen to anything I might have to say. As an engineer who has patents in the area of both aviation and automotive safety, I have an opinion that might have been worthy of Tesla's hearing. I now suggest you folks warn people that Autopark should not be used to complete the parking procedure unless and until Tesla decides to address this problem. In the meantime, drivers should be cautioned to either not use the feature or to tap the brakes lightly to disengage the feature several feet before reaching the back of a parking space. The driver can then complete the maneuver manually.

Driving Southeast on [XXX] between Gallup, NM and Albuquerque, NM. I was traveling at 75 MPH on an open road, it was a sunny day. I had the adaptive cruise control engaged (ACC). Literally no traffic in front of me for as far as the eye can see. Nothing that would cause an alert or obstruction in front of the car. The Tesla was on ACC and suddenly braked, hard. I immediately disengaged the ACC and drove manually. It was a frightening incident. If there had been traffic behind me, it would have resulted in a crash, as I would have been rear ended. If the traffic had been a truck behind us, we would probably have sustained extreme injuries. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driving on divided highway at night, the car slowed dramatically at each exit from the highway.

Vehicle braked without warning with cruise control engaged. Luckily there were no other vehicles near us when this phantom braking occurred.

The adaptive cruise control has had phantom braking issues from day 1 of ownership (and through every software release from Tesla as I always update when a new one is available). Most of the time it's not possible to identify exactly what triggers the event. However, on July 27th 2023 I drove from Phoenix to Sacramento via I10, I210, I5 and had 6 phantom braking events. 5 were directly correlated with passing a semi with me in the #1 lane and the semi in #2. I had the car in adaptive cruise control mode, but I maintained steering control. The car approached the semis normally, but as soon as the car was completely alongside the truck it began braking aggressively. More than just allowing regenerative braking to slow the car, the brakes were applied. This did not happen with every passed truck, maybe 1 in 10. One of the 6 phantom events could not be correlated with any clearly identifiable cause. There is no warning when the car begins decelerating so it is a surprise to the driver. Further it is an extreme hazard to following vehicles who WILL be forced to react. I have not directly reported my specific events to Tesla. For one thing they have no reasonable way to do this (online access, phone access. The number they give to report problems hits an automated phone tree where there is no option for reporting issues). Clearly Tesla is well aware of their phantom braking issues. I'm reporting this to you now in order to apply more pressure to Tesla to finally resolve this. In general, considering some of the other phantom braking episode beyond this one specific trip, I have occasionally noticed the car displays a yellow signal light on the driver's display but only while phantom braking has already begun. I believe this is case where the car believed it saw a caution sign or signal light in it's cameras and was reacting to that. There were no signal lights, but the sun was either coming in that direction or reflected off of other vehicles or buildings.

Adaptive Cruise Control. The vehicle in this mode suddenly brakes for no apparent reason which under the right circumstances could cause a collision. Tesla Service Center looked at it but could not reproduce. This has happened many times on various dates not just once. Sometimes it happens more than once on a trip, sometimes it does not happen. This happens with no warning. Tesla knows about this problem for years but has failed to correct.

There was a trash can on the edge of the road and my vehicle was in autopilot/FSD mode and for some reason it swerved over too close to the edge of the road. I intervened in time to avoid hitting the trash can head-on but it still struck the passenger side mirror and scraped across the passenger rear fender. The mirror got slammed into the passenger side door causing damage to the door and trim at the bottom of the passenger side window.

Going north on New York State highway I-87, there is a bridge which results in Tesla Autopilot erroring EVERY TIME AND EVERY DAY and results in a "Full Self Driving Error" which causes Telsa car to brake along with putting on hazard lights. Issue was reported to Tesla, but they responded that it happens to everyone under this bridge so there is nothing they can do right now. The fault occurs on a busy highway at 55mph zone, and happens 100% of time going under the bridge, every single day. The bridge is wide enough that shadow results in error and car loses all understanding of what lane it is in. Today at the Tesla service center, the employees all reported the same issue as well and that there is no idea if it will be fixed. Happens only when using FSD/AP driving support; manual driving is unaffected.

On 10Jul2023, approximately 1:00pm, while traveling southbound on Hwy 69, south of Toll Road 49 in Lindale, Texas, while driving in the right lane and speed set at 75mph, when all of a sudden the car activates the right blinker and - without slowing - pulls into a fairly short, dedicated right turn lane that turns into a business. At the end of the turn lane is a drainage culvert. The route of travel did NOT include a turn and the car should have been continuing straight down the highway. The car enters the turn lane and never slows from 75mph. I immediately hit the turn signal button to use the camera to get a look to my left to see if a car is there and also look over my left shoulder when there was no response (no camera) to activating the left turn signal. This all occurs as my hand is grabbing the yoke and my foot moving to the brake. I see the blue "path indicating line" wavering left and right and then lock into a right turn into the business parking lot at the end of this dedicated turn lane. Again, there is a culvert at the end of the turn lane also. As soon as I see over my shoulder that the lane to my left is clear the car attempts to make a 90 degree right turn at 75mph. At that exact moment I am able to yank the yoke left and tap the brake to disengage the Full Self Driving Beta as the car is starting the right hand turn. The rear end of the car breaks loose and slides as I get the yoke steered into the right hand lane of the highway. I allow the speed to bleed off to get the rear tires behind me and continue on. My dog has been thrown around the back of the car, my wife banged her head on the passenger side window. This whole event occurred in mere seconds.

Third time this week I have been thrown forward into the steering wheel with no cars or objects surrounding me.

Another automatic phantom braking throwing us toward in the car with no objects or other cars in proximity.

Oncoming vehicle suddenly turned in front of 2021 Tesla Model S resulting in collision at 34mph. Automatic braking did not engage, collision warning system failed to sound alert. Air bags deployed however seat belt completely spooled out causing the driver to strike the windshield and break the glass by contact with the top of the head. The vehicle was a total loss and the dealer never inspected the car.

When using adaptive cruise control vehicle randomly applies brakes while driving at highway speeds, for no reason. Sometimes braking is severe, sometimes moderate, sometimes light. In the instances of severe or moderate braking, a real danger exists that following vehicle will be unable to stop and will collide. This happens relatively frequently, particularly on some highways. Sometimes multiple incidents occur on one drive.

Vehicle is typically operated in FSD Beta mode. I have had approximately a thousand driver initiated disengagements due to unsafe or potentially unsafe operation in Beta mode. At times there have been indirect indications of unintended vehicle operation potentially due to anomalies with system hardware and communications between modules and control systems. The refreshed S and Y models feature a vehicle display behind the yoke steering wheel. When at stop signs, stop lights, or when turning, the yoke (in an upright or near upright position) blocks safety related displays indicating intended vehicle path, bollards and critical safety-related driver annotations. Visibility of these safety critical displays is further degraded when stopped making unprotected turns with the yoke erratically moving. The ability of the driver to safely takeover control of the vehicle is further degraded by the chaos associated with the yoke whipping back and forth on unprotected turns, and drivers and passengers being unable to see critical displays. When the vehicle, driver and passengers all have a reduced capability to ensure safe operation the chaos further degrades safe vehicle operation. At a minimum an over the air recall is required to add safety critical displays/annotations to the large rectangular display between the driver and front passenger similar to Y and 3 models. As noted above I also have hardware related concerns on my vehicle which at times appear to be masked/accommodated by the firmware but are more evident on secondary systems independent of safe vehicle operations.

The Traffic-Aware Cruise Control has been braking unexpectedly and for no valid reason. The most recent example was when we were driving along US Hwy 24 between Wilkerson Pass and Fairplay, CO. The car suddenly braked even though there was no hazard. This has been happening regularly on this drive, in both directions, multiple times per drive. When this happens, the road is generally straight, with little, if any, elevation change. This is a safety issue because if this happens when a car is driving closely behind us, the unexpected braking could result in a rear-end collision. I have not reported this to Tesla because I understand this is a widespread issue that many people encounter, so I believe Tesla is fully aware of the issue. This problem seems to have gotten significantly worse after Tesla deactivated RADAR in the vehicle (without my consent). My understanding is that they are now using only cameras to manage Traffic Aware Cruise Control. Regardless of the reason, this issue has been happening with much greater frequency since around December, 2022 or January, 2023.

Our Tesla, in the "Full Self Drive" mode, has on more than one occasion applied the brakes suddenly without warning while traveling on the freeways. The date I indicate below was the last occurrence. I see that others have indicated this malady and I wanted to add our voice to this conversation. Thank you

When in autopilot, at highway speeds, the car suddenly will brake. There is nothing that instigates this and it seems to be a safety hazard.

In August 2022 I was driving my Tesla S. I was traveling 25 miles an hour or less. I unfortunately lost consciousness for a very short time. My tesla then crashed into a parked car. There was snow emergency braking nor any emergency alarms. In theory describes shouldn’t of happened with an emergency braking system.

Today was at least the 3rd time "phantom braking" has occurred. While traveling on I-64 in Virginia, my speed was about 75mph with adaptive cruise control on. Suddenly, the car braked hard, slowing to about 40mph. I thought the car was going to stop. Fortunately, there were no vehicles behind me or there could have been a rear end collision. I did not use the automatic feature again for the rest of that drive.

Car repeatedly, randomly slams in brakes while cruise control engaged for no apparent reason. Not speeding, no other cars or blockages around, open highway on a bright, clear day.

The vehicle intermittently brakes for no reason with the cruise control enabled. This is going to cause an accident.

The contact owns a 2021 Tesla Model S. The contact stated while driving 70-75 MPH with the Autonomous Self-Driving feature activated, the vehicle experienced phantom braking on numerous occasions. The dealer was made aware of the failure and informed the contact that the vehicle performed as designed. The vehicle was not diagnosed nor repaired. The manufacturer was made aware of the failure. The contact related the failure to the Full Self-Driving (FSD) Beta 10.69.2.2 software update. The failure mileage was 17,102.

Mileage: 17,102

On at least nine occasions the car has very suddenly and with no input from driver braked hard during passing another vehicle, when assuming the original lane after passing a vehicle, and, on one occasion when no other vehicle was close by. I have brought all incidents to Tesla's attention. They tell me the problem resides in the software of the car and that they "are working on it". This is a very serious problem, which has been going on for over a year in my case. A totally unacceptable and extremely dangerous situation! Occurred in December 21, 2020; Several times during the summer of 2021, other sporadic times, and most recently on September 6 and 8, 2022

The contact owns a 2021 Tesla Model S. The contact stated while driving 72 MPH with the autonomous self-driving feature 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 56,292.

While using wildly falsely marketed $10k "full self driving" add-on across multiple software revisions and after reporting each and every bug to company I have experienced potentially fatal phantom breaking while at highway speeds and could have been killed by rear ending on at least 4 occasions. Have experienced 20+ erroneous forward collision errors with automatic breaking or lane assist corrections for obstacles such as hills, mailboxes, trees, absolutely nothing at all, etc. When driving around mildly banking left turn corners with 45mph speed limits whenever approaching a left turn lane within median the car will violently lurch into the turn lane causing panic for passengers and nearly causing a collision within resuming concrete median. While using autopilot the car failed to stop, correct or warn when a vehicle entered my lane and caused an accident with several thousand in damages. Car does not properly break for turns on highways requesting driver take over for what should be an easily navigable turn. Doesn't take apex or break early and will drift lanes making other surrounding drivers nervous. Moving the horn from muscle memory location to awkwardly placed touch button has prevented timely use of horn on multiple occasions which could easily result in fatal accidents. Overall this car is a literal death trap not at all even remotely ready for production use on public roads and neither I nor any of my passengers feel safe using the feature that was over priced, over promised and under-delivered. Tesla service center employees too worried about retaliation from management to inquirer about problems because of previous reparations from corporate offices. List of problems is shockingly egregious and should not be legally permitted on roads.

On 4 Aug 2022, at 10:24am (CST), while traveling northbound on Hwy 287 just south of Henrietta, Texas with the Tesla Autopilot speed set at 80mph with a posted speed limit of 75mph, the car was in the left lane of a two-lane, high-speed highway, when the car suddenly and unexpectedly slammed on the brakes, gave a "TAKE CONTROL IMMEDIATELY" warning and rapidly shifted its lane position, almost causing a wreck with the car behind me. There were no vehicles beside me and nothing to the front or sides to cause concern or indicate that there was any reason for the sudden and abrupt braking maneuver.

The contact owns a 2021 Tesla Model S. The contact stated while driving approximately 45 MPH, the vehicle approached another vehicle that had slowed for a traffic light and did not automatically start braking. The contact manually applied the brakes, but the vehicle crashed into the rear end of the vehicle in front. The contact stated he noticed no warning lights illuminated nor warning chimes sounded advising of a vehicle ahead. The contact said both air bags deployed. The vehicle had crashed and damaged the entire front end which crumpled to the front tires. The police were on the scene and filed a report. The contact and the occupant of the other vehicle were not injured. The vehicle was towed to a collision center. The vehicle was not repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 1,000.

Mileage: 1,000

The vehicle put the brakes on when on adaptive cruise, but with very few cars around. The last time, there was no car in front of me, but the vehicle braked so fast the the car behind me almost rear ended me. I’ve noticed that it happened twice on a South bound stretch of I-35 in Temple texas. This needs to be addressed or there is a strong potential for an accident.

On March 18th and March 19th we have experienced 4 episodes of unexpected emergency phantom braking while using auto pilot. Once on the 18th and 3 times on the 19th. Only once was there another car in our vicinity and that car was next to us within their lane passing us at the time. All 4 times the cars collision warning chimed and hard emergency braking was applied by the car for no reason. If there had been cars following us we would have been rear ended. To date these are the only times this has happened. Tesla says they have no current fix. There was no indication of any problems with the auto pilot/collision warning prior to this.

Car experienced “phantom braking” at freeway speeds (it suddenly and unexpected applied brakes by itself) - AutoPilot was engaged and was on freeway. There were no vehicles or objects in front of car. It was a multi lane freeway and multiple lanes on either side. Was extremely dangerous and could have caused a severe accident had i not taken evasive action and taken control/overridden immediately (would have otherwise been rear-ended).

With autopilot engaged, the vehicle will randomly apply brakes at highway speed with no vehicle in front of it at a distance of at least 1/2 mile. The issue seems to be weather independent. The issue occurs on every occasion where autopilot is engaged at highway speed. I scheduled a maintenance appointment for the issue. My last Tesla model S (2018) did same thing with less frequency. Severe auto braking at highway speed presents serious danger to vehicles behind me.

Third time this has happened on my new Model S Plaid. On Autopilot, the car randomly slams on the brakes when we were driving down the interstate at 70 mph for no reason. There were no other cars around us.

While in autopilot, the car brakes for no reason, phantom breaking. This happens while in right lane near exits, and happens inconsistently while in other lanes. It dropped from 83 on autopilot to 49 in one instance. The person in the back seat almost drove her head into the back of driver seat. The passengers will never buy a Tesla. Another issue, important controls for the car are not intuitive for use and provide distractions from driving. The blinkers and horn as well as tire pressure gauges and other items necessary for safety are too “non conforming”. Someone please address these issues with Tesla. Also, almost every control is so small and flat with no raised markings, those with essential tremors are susceptible to not be able to reach or activate controls due to the extremely small size of the controls.

when travelling around 70-75 miles on AutoPilot car makes strong brakes which is known as phantom breaking. This is happening every single day on highway which is really scary.

Automatic emergency braking on interstate where it is dangerous to slam on the brakes in the middle of traffic.

I was driving on I39 north of Madison WI this afternoon, it was a clear day with light traffic and early afternoon on adaptive cruise control when the car on two occasions braked hard for no apparent reason. This braking would be a serious safety concern if a car had been behind me, as they would not have anticipated me braking so severely for no reason. From my reading this is a known problem with this car.

Beta Autopilot was engaged, driver had hand on steering wheel, vehicle was traveling less than 35MPH (speed limit) and coming around a corner when it misjudged the road curve. The road curved to the left and as the car took the turn it took too wide of a turn and veered slightly off the road. Unfort the front right side of car went up and over the begining of a rock incline. The front right tire blew out and ONLY the side AIrBags deployed (both sides). The car traveled about 500 yards along the road and then turned itself off. I could not get the horn to work, nor put it in neutral. There were no warning signs before incident. In fact the I belong to a beta driving scoring rating and for that day Tesla rated me a 91/100. I called Tesla roadside assistance and they said they would not provide any help as it was viewed as an accident and not a self-driving issue. It was reported to Tesla and I have called several times to try and understand why the car didn't stay in the lane and why only the side airbags deployed. I reported this to Tesla Customer support and was now told they would not provide any information based upon their analysis, although initially I was told that it would take 5 weeks for engineering to review and get back to me. Vehicle is at repair facility and was told damage to car will be almost $28-30K. Car previously had issues with Forward Collision Warning system going off, although I was not aware there was a recall regarding this exact problem, back in October 2021

My 2021 Tesla S has on multiple occasions hard braked when in cruise control when there were no vehicles in view. All occurrences were on four lane interstate highways with no surrounding vehicles.

On Nov 14 at 09:01 AM while driving on the freeway with clear weather and autopilot is on for at least 15 min and and i am fully attentive and no traffic the tesla auto pilot decided to turn left and hit the cement barrier of the freeway damaging my left rear wheel then it tried to correct it fault by turning right to the right lane abruptly luckily there was no traffic coming on my right side too otherwise it would have been fatal I have the incident recorded by the sentry mode cameras and exact time and sec and the logs of the car black box proves that the tesla auto pilot was engaged at that time when it hit the cement barrier I reported this to tesla so they would take responsibility of their risky autopilot software but they dont care and told me i can report it to NHTSA it doesnt matter to them even with all the documented proof i have

This was a Autodrive malfunction event on a brand new Tesla Model S. I was in standstill traffic when my car, which had been engaged in Autodrive, lurched forward and suddenly accelerated at a high rate of speed into the car in front of us, without any driver prompts. The problem was immediately reported to Tesla who has been delaying in providing the data logs and engineering analysis for over two months. Tesla did what they called a "safety inspection" after the crash and says the car is fine. They have refused to try and replicate the malfunction because they maintain the car is fine. Luckily, no one was injured, and there was only property damage to my car and the car in front of me, but there is something wrong with the software, the cameras, and/or the front end sensors and their calibration for the car to have done that.

DRIVING ON HIGHWAY AT 65-70 MPH WITH AUTO PILOT AND SPEED CONTROL ENGAGED. WENT TO CHANGE LANES FROM LEFT TO RIGHT. PUT ON TURN SIGNAL, CANCELLED AUTO PILOT BY TURNING STEERING WHEEL TO RIGHT AND MOVED TO OPEN RIGHT LANE. THERE WERE NO VEHICLES AROUND US AT ALL. THE CAR SUDDENLY, UNEXPECTEDLY, AND VERY SHOCKINGLY SLAMMED ON THE BRAKES CAUSING ITEMS TO BE TOSSED AROUND IN THE CAR, ENGAGING ALL OF OUR SEAT BELTS WITH SOME DISCOMFORT, AND SENDING SOME LOUD ALARM OR WARNING SOUND TO GO OFF IN THE CAR. IT SCARED ME, MY WIFE AND DAUGHTER VERY MUCH. IF THERE HAD BEEN A VEHICLE IN THE LAND BEHIND US, THERE'S NO WAY THEY COULD HAVE AVOIDED HITTING US VERY VIOLENTLY AND CAUSING INJURY AND PROPERTY DAMAGE. THIS HAPPENED 2 OR 3 TIMES IN MY FORMER 2016 MODEL S, BUT I NEVER EXPECTED IT IN THIS 2021 MODEL. A GOOGLE SEARCH WILL REVEAL THE VAST NUMBER OF TESLA DRIVERS WHO HAVE HAD THE SAME OR SIMILAR EXPERIENCES.
