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.

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
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.
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.
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.
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.
The contact owns a 2022 Tesla Model 3. The contact stated that while driving approximately 60-70 MPH, the vehicle independently stopped without warning. Also, while driving approximately 80 MPH, the vehicle decelerated independently to 20 MPH abruptly. The contact stated there was an abnormal beeping alert prior to the failure. The vehicle was taken to the local dealer, where they informed him, they were waiting for a firmware update. The vehicle was not diagnosed or repaired. The vehicle was taken to another local dealer, Tesla (9140 E Independence Blvd, Matthews, NC 28105. The manufacturer was notified of the failure but no further assistance was provided. The approximate failure mileage was 7,826.
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.
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 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.
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.
On a two lane road doing 60 mph, with vehicle on cruise control, it slowed rapidly to about 30 mph all on its own. When I say rapidly like right now-I was afraid the vehicle behind me would not be able to stop. Then accelerated back to the set speed. NO WARNING…..this problem is easy to duplicate. As of now I cannot use cruise control too dangerous.
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
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.
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)
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.
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.
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.
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.
The contact owns a 2022 Tesla Model 3. The contact stated while driving approximately 65 MPH, the vehicle inadvertently started braking with the cruise control was activated. There was no warning light illuminated. The vehicle was not taken to the local dealer. The manufacturer was informed of the failure and was awaiting a response. The failure mileage was approximately 1,500.
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.
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.
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.
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.
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.
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.
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.
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”.
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.
