Service brakes, Forward collision avoidance, Mar 1, 2022
On several occasions (probably around 10 times) since I purchased the car in November of 2021 I have experienced phantom braking while using adaptive cruise control. Most have been minor with a couple instances of severe braking that could definitely have caused a rear end accident if there were cars behind me. These have occurred on busy city streets while traveling 40-50 mph. None have occurred on freeways. I have not notified Tesla but see that others are having problems too. Software appears up to date.

The contact owns a 2021 Tesla Model 3. The contact stated while driving approximately 75 MPH, the vehicle decelerated inadvertently. The contact stated that the vehicle would detect a non-existent road hazard causing the vehicle to slow down dramatically, almost causing a rear-end crash. The contact stated that there were no warning lights illuminated. The contact stated that while researching online he became of similar failures. The dealer and the manufacturer were contacted; however, no assistance was offered. The approximate failure mileage was 10,000. On a recent trip up the same two-lane segment of US-95 where chronic incidence of my 2021 Tesla Model 3 suddenly removing acceleration causing a very dangerous unexpected drastic slowing from high speeds, recurrence of this problem indicated what might be causing the problem. There are certain times of day when on a mostly level asphalt roadway it appears there are patches of water or grease on the pavement when seen from a distance.

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.

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
Vehicle speed control, Forward collision avoidance, Feb 25, 2022
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.

Adaptive cruise control engaged. Traveling over the crest of a hill after dark, the brakes automatically applied hard when an oncoming vehicle approaches uphill. This has occurred on several occasions.
Vehicle speed control, Forward collision avoidance, Feb 22, 2022
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.

Was driving on clear roads, there was a driver ahead of me but they were over 100 yards away, the vehicle behind me swerved to make sure they didn't get hit by my car's auto-braking safety feature. the vehicle was on autopilot using adaptive cruise control and just randomly used the safety feature without any warning or indication that there was any object on the freeway. The Incident had occurred in the morning on the 405s freeway.
Forward collision avoidance, Feb 21, 2022
This complaint was prompted by reading recent news reports of 'phantom braking' with our model vehicle. Previous to these reports, I did not have an awareness of NHTSA and their reporting mechanism. Driving on a highway, adaptive cruise control application. Sudden braking applied without my foot touching brake pedal. It was a sunny day, without any obvious need for braking. I was able to apply acceleration which terminated the braking cycle. No harm done, however if there was a car behind me there could have been a significant car accident at high speeds (>70 mph). This 'phantom braking' also occurred late 2021, also at highway speeds, on at least two occasion on the same trip cycle, in similar driving conditions (clear, dry). Nothing has been inspected. No indicators or warning lamps or messages applicable.

Three times so far in a week, the car has had extreme hard breaking on the freeway. These were done in full self drive mode. Absolutely terrifying and so unsafe for my family to have this happen.
Forward collision avoidance, Feb 20, 2022
When driving on one way road and a vehicle is travel inbound. The vehicle will stop extremely hard without any notice of anyone or anything in front of me. Even when travel on a open highway the vehicle will sometime stop extremely hard and freak out like something is in front of me when their is nothing.

At highway speeds while using cruise control I experienced several times what is now being called phantom braking. I have ceased using the cruise control as this is a scary problem.
Service brakes, Forward collision avoidance, Feb 20, 2022
The car will brake seemingly for no reason while on Autopilot. The environment does not change at all, yet the car will randomly brake very hard as if someone was in front of me and slammed the brakes. It also happens very commonly, more common than tolerable. No warning beeps or chimes or any indication of anything event. I'm not sure if this is inspectable, I have brought the car to service a few times under warranty for unrelated issues. This problem is pretty much widespread across Tesla's autopilot system. This has happened many times, but the most dangerous one by far was on I-75 and slammed the brakes from 85 to 45-35 in a matter of seconds.

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.

Driving on an open 2 lane highway between Lecanto and Gainesville, car slammed on the brakes while in autopilot. There were no obstructions or other reason to stop.
Forward collision avoidance, Feb 19, 2022
Similar to the reporting of others, I wanted to confirm that we had a problem with our Tesla 3 auto-pilot feature erroneously triggering emergency braking by misinterpreting oncoming traffic. This happened twice in a similar situation. While driving on a single-lane highway in auto-pilot, the car abruptly braked when a semi-truck passed in the opposite lane. This sudden deceleration could have lead to a rear-end collision but fortunately the driver behind had left enough breaking space. The same thing occurred again on the same road - also with a semi-truck in the opposing lane. This time, vigilant that the auto-pilot might be malfunctioning, the sudden breaking was quickly overcome by pressing the accelerator. There is no doubt on our end that the current version of the auto-pilot will trigger emergency braking mistakenly based on misinterpreting opposing traffic.
Lane departure, Forward collision avoidance, Feb 19, 2022, crash
The car was on FSD jerked right toward a semi truck then jerked left toward the posts in the median as it was accelerating and FSD would not turn off. Was trying to control the car but it kept pushing and accelerating causing us to crash in to the median posts. Normally FSD would turn off if it was unsure but this day it would not. Plus other times it would phantom brake if we were on 2 lane road and met on oncoming large truck. We also had other times of phantom braking going over a hill. We have reported this to Tesla but no response yet. We owned this car 11 days when our wreck happened.

While driving on the highway without any cars in front of ours, three times the vehicle slammed on the emergency braking system and attempted to stop the car causing cars behind us to slam on their brakes to avoid hitting ours.

My 2021 Tesla model 3 has a issue of what is called Phantom Braking. On 2 lane undivided highways and on all types of roads the car will randomly slam on the brakes to what I assume is to prevent hitting a obstacle that doesn’t exist. The car will apply the brakes extremely fast and drop roughly 20 MPH or more in just a few seconds. I am unable to use cruise control on 2 lane highways because it slams on the brakes it seems like anytime it sees a dip in the road or a mailbox on the side of the road it triggers the emergency braking system. I feel lucky that no one has been behind me while these events have happened. It happens almost every time I drive the car. I have contacted Tesla about this issue and they say everything is fine and they would rather have a lot of false positives than to miss a actual event. I feel like it is a very unsafe feature and needs to be addressed because other manufacturers have this down with hardly any issues. This has been happening on the car since it was new and has not improved the car has 7500 miles on it.

When in Autopilot mode, the car will sporadically brake without any obstacles in front of it. This has occurred to me about half a dozen times. Always on the highway. Initially it would happen in the daytime near overpasses or when entering shade from a sunny area. Twice it occurred to me at night, on a well lit interstate in an urban area. This is often referred to as Phantom Breaking.

I was driving my car and had it on autopilot. The road was empty and all of a sudden the car decided to apply brakes when nothing was infront of it. I was able to take control instantly to prevent a sudden stop however I was lucky there were no cars behind me

With the Autopilot engaged on the freeway I have had several of these phantom braking experiences but last night I was lucky to avoid a accident with the car following me.. This happened at 74 miles per hour with the autopilot engaged the brakes slow me down to 60 miles per hour before I could disengage the autopilot.

When the vehicle is in autopilot at high speed, it breaks suddenly without any visible obstacles. This happens at Kraft once every 200 miles of highway driving with autopilot on. The speed drops suddenly from 75 mph to 40 mph.

The car has twice gone into emergency braking mode on the interstate for no good reason. One incident was as the car was approaching a dark shadow area under an overpass, and the other was in a construction zone and I have no idea what triggered it. In both cases if someone had been following closely I may have been in trouble.
