2019 TESLA MODEL 3 Forward Collision Avoidance Adaptive Cruise Control Problems

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

While freeway driving with autopilot (adaptive cruise control) engaged the car will suddenly break VERY hard when there is no reason to. This is SUPER dangerous when traveling at 70 mph and someone is behind me. This is a known issue (phantom breaking) that has been a problem for years and not resolved.

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

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

I was traveling approximately 70 mph in passing lane when I engaged (standard) autopilot, as I approached to pass a vehicle with another vehicle following me in the same lane as I was traveling. My vehicle (phantom) braked hard to which the wheels began to squeal slightly and the vehicle behind me had to brake hard to avoid hitting my vehicle. I almost immediately applied pressure to the accelerator pedal to avoid a complete stopping of the vehicle and to which the vehicle responded to accelerate. And I disengaged the autopilot immediately by applying an upward motion on the gear stock.

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

Car is on cruise control on a two lane highway, posted speed 55 mph. It has ghost emergency stops on cruise control not auto pilot . My car doesn’t have it. It renders a simple feature unusable.

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. The vehicle made a turn left and found itself in a lane that was coned off. Traffic was queuing in the adjacent lane. The vehicle edged forward into the closed lane and waited to join the lane to the right. Even though other drivers were giving way, the vehicle failed to move. The driver took manual control in order to complete the manoeuvre.

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. Cruising at 30+ mph the vehicle was late to slow down ahead of a left turn junction. The vehicle then cut across the junction as it was moving too fast to make the turn correctly. There is Go_Pro footage of the incident here... https://vimeo.com/738674524/5db5854102

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. After successfully crossing a junction the vehicle accelerated too quickly on a narrow residential road with another vehicle approaching from the opposite direction. The vehicle was travelling at 27 mph when it was forced to brake hard. There is Go_Pro footage of the incident here... https://vimeo.com/738677992/0a3c3d4713

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. The vehicle stopped short of a STOP sign at a junction then slowly moved to the middle of the junction, failing to make a right turn. After manual re-routing the vehicle brakes for no reason other than a pedestrian is close by. The vehicle then fails to make a left turn successfully, cutting the corner. There is Go_Pro video here.. https://vimeo.com/738680260/7c4eeba7e2

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. The vehicle approached a busy intersection to turn left. Although drivers were giving way to the vehicle, it failed to complete the turn in a timely manner. The vehicle edged forward and then rapidly made the turn at 12mph . The driver had to take over as the FSD made the turn too sharply and too close to a bollard. There is Go_Pro video here https://vimeo.com/738682868/d5b572a69d

Yesterday I had the most frightening driving experience of my entire life. It was raining heavily and I was going about 35 mph on the local road in my model 3 standard, 3 years old. Suddenly I lost all traction and was slipping side to side +/-90 degrees from the direction of traffic. I immediately took my foot off the accelerator and tried to slow down but didn’t brake. I swung 180 degrees each way about 5 times. Luckily no one hit me but I was taking up all lanes as I careened all over the road. I can’t believe how easily the model 3 loses traction in the rain. This is unacceptable.

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. The vehicle was navigating through roadworks with temporary signage and cones in place. This seemed to interfere with the FSD with the vehicle moving left to right in an erratic manner and accelerating to 28mph whilst still in the roadworks zone. There is Go_Pro video of the incident here https://vimeo.com/736104870/581215a7e7

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. At 10mph the vehicle attempted to change lanes whilst there was another vehicle in the other lane. If the driver had not intervened there may have been a collision or the other vehicle would have to brake hard to avoid contact. There is Go_Pro video of the incident here. https://vimeo.com/736107290/2a01155c84

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. At approx 20 mph the vehicle entered a stretch of road works with temporary signage and cones. The vehicle performed an emergency stop for no reason to the frustration of other road users. The driver had to take control of the vehicle. There is Go_Pro video of the incident here. https://vimeo.com/736110202/bcedc1c516

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. At 25 mph the vehicle veered across two solid white lines and into the cycle lane. There is Go_Pro video of the incident here. https://vimeo.com/736112946/2d0d7a4ed3

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. The vehicle failed to recognise a speed limit change approaching a sharp left turn. The vehicle took the turn too fast at 29mph veered into the oncoming lane. The quick reactions of the driver, who took control averted a collision. There is Go_Pro video of the incident here https://vimeo.com/736115753/289c3413e9

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. On a section of road with a 15 mph limit the vehicle was travelling at 39 mph. It then attempted to take a corner at 25 mph veering into the oncoming lane. Vimeo Link - https://vimeo.com/735797650/15baa75187

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. On a section of road with tight, blind turns, the vehicle accelerated from 23mph to 27 mph into the approach to a turn. In making the turn the vehicle crossed the median into the oncoming lane. There is a Go-Pro video of the incident here https://vimeo.com/735805944/eab3a31083

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. On a wide residential road, with a speed limit of 30 mph, the vehicle accelerated to 44 mph. The display on the vehicle incorrectly says the limit is 65 before the driver had to manually adjust the maximum speed. There is Go-Pro Video of the incident here https://vimeo.com/735815741/e651f8ab92

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. At 45 mph and without indicating etc, the vehicle swapped lanes from left to right on a dual lane highway. There is Go_Pro video of the incident here. https://vimeo.com/735819637/601febb81d

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. Cruising at 35 mph on a broad residential street, the vehicle failed to recognise road markings and signage indicating that the vehicle was entering a “slow school” zone. There is Go_Pro video of the incident here https://vimeo.com/735823359/7795c10089

While driving on the freeway tonight at about 11:45 pm with no one nearby and no shadows or debris in the road, the car on autopilot slammed on the brakes, taking the car from 68MPH to below 45MPH in less than a second, which could have resulted in a rear end collision had someone been behind the car. The car has done this many times in the past but this time was unusual in that three beeps occurred right as the car slammed on the brakes. I saved the video and will see if the video shows the incident.

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. While FSD was engaged, the driver approached a road closure sign due to road works occurring. Ignoring these well-marked signs, which clearly said 'Road Closed', the Tesla proceeded past these signs until the driver had to perform a stop to prevent the vehicle from colliding with the road works. A link to the clip of the incident can be found below: https://vimeo.com/733970645/9ef2ad21d2

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. While FSD Beta was engaged, the driver approached an intersection, the FSD stopped correctly to yield to oncoming traffic on a one-way street. The vehicle was travelling across the intersection according to its navigation. There was also a cyclist ahead of the Tesla at the intersection. As the cyclist entered the intersection, the Tesla followed and attempted to travel around the cyclist to complete the manoeuvre and continue travelling straight ahead. However, the Tesla then deviated from its course and instead travelled left at the intersection, travelling the wrong way on one-way street, causing the driver to perform an emergency stop and reverse out of the dangerous situation. The Tesla appeared to panic at the presence of the cyclist when attempting to travel around it, and then headed directly...

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. As the vehicle approached a rail crossing, with lights indicating it was safe to cross, the vehicle rapidly reduced speed from 21 mph, creating a hazard for the vehicles behind. The driver had to take back control of the car to mitigate the risk of a collision. A link to the clip of the incident can be found below: https://vimeo.com/732400249/c1dbfe39dd

My friend was driving the vehicle (Tesla Model 3, 2019) while Full Self-Driving Beta 10.12.2 mode was engaged. The FSD Tesla makes a left turn at an intersection on a protected left turn, but slows down considerably just before the traffic lights - which did not apply to the Tesla but rather the traffic from the opposite side of the intersection - after making the turn, stopping in the middle of the lane. The driver disengages and accelerates to complete the manoeuvre, to avoid a rear collision. The Tesla may have mistaken the red traffic light showing for other traffic as one it should pay attention to, almost causing a collision and displaying the inadequacies of its vision and cameras. A link to the clip of the incident can be found below: https://vimeo.com/732401882/8837a257a0

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. The vehicle was travelling at approx 35 mph - too fast for a narrow and winding road. The vehicle crossed the central line into the oncoming lane and a moment later veered towards the right - nearly making contact with the curb and causing a collision. The driver had to take back control of the vehicle. A link to the clip of the incident can be found below: https://vimeo.com/731689228/485219aa71

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. Travelling on a narrow and winding road the driver had set the max speed to 20 mph. After re-engaging FSD mode the Tesla “reset” the max speed to 35 mph. Clearly too fast for the road conditions, the vehicle had difficulty negotiating the road safely and almost veered into the wrong side of the road. A link to a clip of the incident can be found below: https://vimeo.com/731691467/e336068d60

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

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. The vehicle approached an intersection, on a bend in the road, at more than 30 mph and braked to a near halt whilst in the middle of the intersection. The speed limit is signed at 15mph. The vehicle then proceeds in FSD mode and takes another corner 5 to 10 mph in excess of the speed limit of 20 mph. A link to a clip of the incident can be found below: https://vimeo.com/731419136/51bfb24df3

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. The vehicle was stationary at a “no right turn on red light” intersection. In spite of the sign, in FSD, the vehicle took the turn in “autopilot creeping forward” mode, making an illegal turn on a busy intersection. Please see a link to a clip of the incident below: https://vimeo.com/731427985/e4d022bdea

Car suddenly braked hard while driving 60mph on a highway nearly causing me to get rear ended. No clear indications as to why it braked.

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

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. The Tesla fails to slow down when approaching a curve in the road resulting in taking the corner far too quickly, despite the fact that there is a sign by the road warning drivers to slow down to 15mph. Tesla also failed to recognise the change in speed limit due to a blind turn in the road approaching, the car continued to go at a rapid speed (30mph) and even turned left when the road curved toward the right, leading to the driver taking control to steer the car back on path. During the turn, the Tesla was engaged in FSD Beta 10.12.2 and crossed the dividing line into the opposite lane. If another vehicle was approaching this incident would have resulted in a collision as the Tesla strayed...

My friend was driving my car (a Tesla Model 3) at the time of this incident. At the time of the incident the Tesla’s Full Self-Driving Beta system (version 10.12.2) was active. The Tesla fails to slow down when approaching a series of sharp bends in the road resulting in taking the first corner far too quickly. The posted speed limit according to the sign was 15 mph, however, the Tesla was travelling at approximately 30mph, double the posted speed limit. The Tesla therefore drives into the turn too widely and tries to steer into the oncoming traffic lane, forcing the driver to intervene quickly to correct the manoeuvre and reposition the car back into the lane. During the entire incident, the car was travelling, autonomously, at 25mph. Please see below a link to a short video showing this incident: https://vimeo.com/720341558/004264b711

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. The vehicle was travelling at 21mph approaching a railroad crossing in moderate to busy traffic. The crossing was open. The Tesla slowed quickly to 7 mph for no reason. The driver had to take control of the vehicle in order to maintain progress and not cause a hazard to other road users. A link to the incident can be found below: https://vimeo.com/729934579/b3e3d6438a

My friend was driving the vehicle (a 2019 Tesla Model 3) while it was engaged in Full Self-Driving Beta 10.12.2 mode. The Tesla was in traffic waiting to turn left at an intersection. As the vehicle made the turn it decelerated from 18mph to 10mph at a secondary red light - for no reason. The driver had to take control of the vehicle in order to maintain progress and not cause a hazard to other road users. A link to the clip of the incident can be found below: https://vimeo.com/729935224/032493c7fd

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

Sudden braking / deceleration while on adaptive cruise control. Has been happening frequently on I66 east between Haymarket and Rte 28, often at same locations. No visible hazards and often no other cars immediately in front of vehicle. Vehicle has "Autopilot," not full-self-driving. Has been happening for more than two years.

My car brakes for no apparent reason consistently in the same location every time. What has been described as “phantom braking”. When I hit two spots on I5 northbound near the berkley exit. The set max speed of my cruise control will suddenly drop and the vehicle will brake. The speed then adjusts up to the prior setting and the vehicle will return to normal. This in total lasts about 5 seconds but results in dangerous braking.

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

A Tesla model 3 was eastbound on a two-lane roadway at approximately 7:20am local time. A westbound school bus slowed, and activated its amber warning lights, followed by the red stop lights and driver side stop sign. The Tesla, proceeded through the traffic control devices of the school bus while the bus was accepting child passengers. It was evident that the "driver" of the model 3 had full self-driving mode engaged, and was not fully paying attention to the road as he was clearly interacting with his smart phone, held at steering wheel height. The Tesla FSD system clearly failed to appropriately stop and wait for the school bus traffic controls. Had the students needed to cross the highway (instead of only boarding from the shoulder) a serious vehicle/pedestrian incident could have resulted. NOTE: Model 3 was NOT my vehicle - This form is flawed that it makes the assumption...

The traffic-aware cruise control frequently brakes hard at high speeds (70-80mph). It will brake for no reason, bringing the car's speed from 80mph to 30mph in a few seconds. This happens about 3 times an hour. If there was a car close behind me whenever it happens, this could have caused significant harm. I feel this is an extreme safety risk. My vehicle has not been inspected, but this is a common complaint among Tesla owners in recent months.

I have a Tesla model 3 SR and it only has the standard autopilot option, not the full self driving option. When on the freeway in a single lane and autopilot is engaged, if the single lane splits into two lanes, the car will swerve violently trying to determine which lane to take. This is a danger for the other vehicles behind me, as they are confused as to which lane the vehicle will take. Sometimes it will take a left or right hand turn lane and then start beeping when it determines that it made a mistake. A huge safety risk, as somebody would be thinking that I would move left or right, but instead the car moves into the lane going straight ahead at the last minute.

Even after the firmware update which was supposed to have FSD beta come to a full stop, the car still does not come to a full stop. The car slows to a speed of around 0.5 mph at a stop line with a stop sign and continues on if it is clear, but only comes to a full stop if it believes it needs to yield to other vehicles. Watching videos of other vehicles demonstrating the capabilities of FSD beta with the latest firmware version show the same behavior.

While driving on I 70 in Kansas with cruise control on, the car violently decelerated several times during a trip. This happened with no reason, with no object in the vehicle path and was like someone jamming the breaks and tire nearly skidding. If someone was behind me they surely would have rear-ended my car.

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

Automatic Cruise Control and Tesla's Auto Pilot feature phantom braked extremely aggressively when it saw on coming traffic. Sometimes without any traffic. Through a roughly 1,200 mile road trip it happened at least 2-3 dozen times to the point where I turned it off concerned it might phantom brake aggressively with a car behind me and cause me to get rear ended. Sometimes it would give me alert sounds, sometimes it would just brake. This was never nearly as much of an issue until the November update of 2021.
