Vehicle speed control, Forward collision avoidance, Jun 4, 2022
The autopilot used for automatic cruise control regularly brakes for unexplained reasons when there is no immediate threat. This is not only scary but it could cause an accident if other cars were right behind me. There is one part of highway 470 in Highlands Ranch, CO, where it happens every time, like autopilot is expecting the speed limit to drop so it slows way down for me, but the speed limit hasn’t changed. Other times it just happens randomly. It will happen at least once usually every hour I use autopilot.

The car, when using its "traffic aware cruise control" exhibits extreme sudden breaking for no reason (phantom braking). On Thursday, I was on a major interstate in the middle of the day, perfectly marked lanes, no gradient changes, no weather or visibility issues, with absolutely nothing in front of me. The car would suddenly brake aggressively for no reason, sometimes hard enough to hurt my neck. If another car had been following me, I would have been immediately rear ended. Too add insult to injury, Tesla charges for the full self driving function which fully navigates the car on highways, and even though it is so dysfunctional that it is dangerous, they will not refund it after I reported this behavior. Tesla FSD and traffic aware cruise control, in it's current state, is a danger to the public.

The Tesla Autopilot system in my Model 3 repeatedly malfunctions by way of "phantom braking".The latest incident I was luckily able to capture on camera. In this incident, my vehicle is driving down a Nevada highway in the heat, with no oncoming vehicles and a vehicle in my lane well over a mile away and increasing (they had just passed me a few minutes prior). With the speed set to 74mph (driving 73 at the time) the vehicle proceeds to apply heavy brakes, and slows to 56mph for no reason (no vehicles behind, thankfully). My safety and the safety of other motorists is put at risk with these events as the unexpected braking not only whips around the passengers of MY vehicle, but also puts at risk any vehicles that may be behind me, expecting me to maintain my current velocity. The problem has not been reproduced by a dealer as far as I am aware, but the service department of my local Tesla dealer has confirmed the issue is caused by the "Tesla Vision" camera-only system. They (service team) claim that there is no issue with the system, and that it is behaving as expected. They do not view this as a malfunction, and merely view it as the system being extra cautious, which is simply lazy. This component has not yet been inspected by any entity mentioned above. There were no symptoms of this issue prior to it occurring, however this did occur repeatedly over the course of my trip to/from Las Vegas.
Electrical system, Vehicle speed control, Other or unspecified, Apr 30, 2022
We were driving on the freeway at 69 mph and suddenly with no warning the center console main screen froze. All electronic functions of the car stopped and the car was stuck at 69 mph. Speedometer And turn signals did not work. We managed to get to the side of the road (mechanical brakes and steering were unaffected). The car could not be put in Park so a manual reboot was not possible. The car rebooted itself (screen went black and then came back online) after about 10 minutes or so and then the car functioned normally.

The contact owns a 2021 Tesla Model 3. The contact stated while her son was driving 70 MPH on autopilot, the vehicle independently decelerated to 45 MPH. The contact stated no warning light was illuminated. The driver was able to continue driving to his destination. 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 8,900.

While driving, typically on two lane roads with oncoming traffic, the vehicle will suddenly break hard for no visible reason. Often it is the case that the vehicle breaks so hard that things in the car fly forward and the seatbelts lock up causing people to grunt at the force and scream. This happens while using full self driving or just regular cruise control. There is no warning and people behind my vehicle have a high likelihood a rear ending me since there is no visible or obvious cars for my breaking. Also it would appear that I am brake checking the person behind me, causing them to become angry with me through no fault of my own, but it is understandable based on the reaction of my vehicle. When this happens I typically report the issue directly to Tesla using their voice feature to report issues. The command is typically “bug report phantom braking.”

Brakes were automatically engaged and speed dramatically reduced on an otherwise deserted, two-line highway. Speed was reduced from 68mph to 30mph in a few seconds multiple times in the span of two hours. Adaptive cruise control was active at the time. This would put myself and any vehicles behind me in danger, so I disabled the feature for the remainder of the drive. The behavior has been reproduced multiple times since then, in various conditions. No warning lamps or other messages appeared at the time. I reported the problem to the manufacturer and schedule a service appointment. The manufacturer canceled this appointment, stating, "Our technicians will be unable to change this behavior."

I was driving on a divide highway at 70 mph in the HOV lane with cruise control activated, not auto steering, when the car abruptly slowed down. No car was visible in front of me. If someone was following closely behind me an accident could have occurred. I reported this to Tesla.

When the cruise control is set at a speed or the line centering cruise control is used the car will slam on it's brakes and go from the set 75 to between 50-60mph then back to the set speed. This happens almost every time I drive the car on the highway and a few times in town(35mph) it happens so often I stopped using cruise control because I am afraid of getting rear ended. I have been looking online and others are calling this phantom braking.
Vehicle speed control, Forward collision avoidance, Feb 28, 2022
Our company Model 3 is having repeated phantom braking issues either in Traffic Aware Cruise Control (TACC) or in Autosteer mode. Through time we have determined some expected situations but there are also many other times totally unexpected. The most common situation is while driving in TACC mode (standard cruise control) on a standard highway (one lane each direction) and passing a semi-truck. This situation results in phantom braking about in about 50% of instances. Beyond semi's, phantom braking can occur from other vehicles, shadows from trees, going up or down small inclines, changes in road coloration (going from cement to black top), and even when no obvious reason is present on a totally clear, flat road. During a 2-3 hour drive the average is about 20 instances of phantom braking. This has been reported to Tesla. They have apparently reviewed the information and determined nothing is malfunctioning with the vehicle and reminded us that Autopilot functions are all Beta and they are not responsible to resolve the problems. Attached below are reports completed for Tesla to describe information about phantom braking instances during a test period which was about an hour of driving.

My Tesla 3 accelerated out of control when parking at my place of work which is a daycare center. I could have killed children, others and myself. My foot was fully pressed on the brake. Tesla is claiming it is driver error. That is false my foot was pressed fully on the brake. Scared to go back in the car. I don’t want that car on the road. I hit the curb went airborne missing a car, sign, brick wall, trees onto an embankment. I have a wittiness too.

Tesla Model 3 Phantom Braking while on cruise control. This car is a daily driver mostly expressway miles and cruise control is used every day for the majority of the drive. While driving on cruise control at 70 miles an hour the car will randomly brake hard enough for all items on the car seats to be sent to the floor. This happens in wide open situations with no other cars around in broad daylight. This has been occurring about twice a month since purchase. I am worried someday I may be rear ended or the car may brake hard into a slide. This has been mentioned to Tesla multiple times at service calls and they say they are working on it

Phantom braking while cruise control engaged. I do not have Full Self Driving, was only using the basic cruise. Appears to be worse when approaching large semi trucks, but has also happened numerous times when absolutely nothing is around (no cars, animals). No warning provided. Example: car will go from 75mph to 60mph in 1 second, then “recover” and go back to 75mph.

I am experiencing phantom breaking on our Model 3. While traveling last weekend on Interstate 5, as well as on CA 101 - the vehicle frequently slowed abruptly while driving at highway speeds. This occurred both with other vehicles around, and with no vehicles present - also while driving at times in clear daylight and while approaching shadows from surrounding objects such as trees or highway overpasses. It rendered the adaptive cruise control non-useable on a 5hr drive home due to the sudden and abrupt slowing of the vehicle.

I currently drive a 2021 Tesla model 3. When I drive this car down two lane highways my cruise control is almost un usable not to mention auto pilot. Almost every time a larger vehicle, something like a Semi truck comes from the other direction in the opposite lane my car slams the brakes. At night time it’s even worse when headlights are in the distance my car slams the brakes and when the headlights are closer it slams the brakes again. It also has random phantom breaking. I tried the service department and the told me it was a software issue and there was nothing they could do. The technician told me it would improve if I purchased FSD. I don’t believe it, if basic cruise control doesn’t work how is FSD going to work. I don’t know who to contact or even what to do about this issue, the service department refuses to even look at my car.

On several occasions while driving in the highway with AutoPilot engaged for adaptive cruise control, the car has suddenly applied the brakes very hard when there were no hazards in my lane. This has occurred on curves in the road when oncoming traffic was detected in the other lane and also when there has been a vehicle stopped on the shoulder.

1) When using autosteer and/or adaptive cruise control the vehicle randomly brakes and very rapidly decelerates. This has occurred on at least a dozen drives, beginning on my first long road trip after owning the car for 2 months. 2) If another vehicle is following my car, we could very easily get into a rear-end accident. This happens at high speeds going from 75mph to 55mph in seconds, so the chance of a collision is high. I also become very scared when this happens which temporarily takes my attention away from driving. 3) No the problem has not been reproduced by a dealer. I live 150 miles from the nearest Tesla dealership. 4) No the vehicle has not been inspected. 5) No warning signs which is why this "phantom braking" is SO TERRIFYING.

During the use of the Autopilot feature in Tesla, the car suddenly starts braking with no obstacles. This can cause a safety incident on the road when there are vehicles behind and the Tesla suddenly stops for no apparent reason.

On 2/17/22 at appx. 8:08am with adaptive cruise control engaged the collision warning alarm chimed and the car beaked quickly for 50mph to 30 mph. There was an SUV in the oncoming traffic lane. This has happened several times. The system sometimes does not recognize that approaching vehicles are in a correct lane. This happens with larger approaching vehicles such as large SUVs and trucks. Additionally we have been getting many (dozens) of dashboard error warnings that one or more of the cameras are blocked or blinded. As Tesla has chosen to delete lidar and depend solely on cameras as safety system detectors this affects Adaptive Cruise Control, Automatic Emergency Braking, Blind spot warning, Forward Collision Warning, Lane Departure Warning, Lane Keeping Assistance, and cross traffic alert.

I've owned this vehicle since October of 2021, and wish to provide examples of my own issues concerning phantom braking while using the Autopilot/Traffic Aware Cruise Control Feature on my Model 3 Standard Range Plus. Having now put roughly 6,000 miles on the vehicle in the conditions found in western Maryland/south-central Pennsylvania, I've been able to find these consistencies concerning phantom braking: On an undivided 2-lane highway: 1. When it's a dashed line that allows for passing on long straight stretches, more phantom braking incidents occur than when the center line is double-solid. Those are usually 5-15mph braking events until the opposing vehicle has passed without incident. 2. When going down/up a gently sloping hill and the car is unable to see the lines far enough ahead because of a turn. If a vehicle is coming the opposite direction, the car appears to believe that the opposing vehicle is in your lane and coming right at your vehicle. These are usually the hardest phantom braking events. 3. When vehicles are parked parallel along the side of an undivided road, and especially at night, the car appears to think these are threats to its/my safety. I say that they appear worse at night, as when my headlights cause the rear taillights/reflectors to visually brighten, the incidents are more frequent. These vary wildly, from having no braking events to hard braking events. On a divided highway: The most consistent issues in my case happen when going up/down mountains. A highway turns into 3 lanes, with the rightmost lane for large, heavy trucks that are going slower than the rest of traffic. If you are in the middle lane, and that slow truck is using it's 4-way blinkers, Autopilot/TACC appears to see it as an emergency vehicle, and heavily brakes. I've gotten in the habit of always using the leftmost lane to avoid this issue. The trucks are clearly in another lane, well out of mine, and are moving, even if slower than the rest of traffic.

On multiple occassions, while using the adaptive cruise feature, (but not the auto steer feature) the vehicle will suddenly slow down to the speed limit, without any warning or notification that anything has changed. This happens in multiple occasions on the Long Island Expressway between exits 48 adn 32. The vehicle slows by itself for no reason at all. fb

I owned this 2021 Tesla Model 3 for six months. On many occasions, while using the adaptive cruise control mainly on two-lane roads at various speeds between 35-55 MPH, the car would unexpectedly rapidly apply the brakes when there was no hazard present. This almost got me in a road rage situation, as the following vehicle thought that I intentionally brake-checked them. I discontinued using the system. I no longer on this vehicle, but can provide new owner’s information if needed.
