2022 TESLA MODEL 3 Forward Collision Avoidance Automatic Emergency Braking Problems

My car suddenly braked for no reason. I was at risk of a rear-end collision. I called Tesla and they instructed me to reboot my computer. They said an engineer would review the computer records and get back to me. No follow-up has happened yet. No, the vehicle has not been inspected. Before the incident, I heard a warning signal.

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...

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...

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.

While driving on the interstate with the adaptive cruise control engaged I’ve now had four incidents where I’ve had to over-ride the system because the car mysteriously slammed on the brakes attempting to stop the car when no threats were apparent. These were frightening and dangerous events. I’ve had several cars with adaptive cruise and never experienced this type of un-provoked emergency braking. The for situations were as follows: 1) The road gently curving to the right while I was in the second to far left lane and there was a concrete barrier left of the far left lane divining the opposing lanes. The car apparently mistook the barrier as a threat because it slammed on the brakes without warning. I override the system to avoid a collision from behind. 2) Driving down a three lane road in the center lane when a car entered the road into the right...

My mother was driving my brand new 2022 M3P from Garfield, AR, to S. Coffeyville, KS, on a two lane highway when we experienced a major AEB event while in cruise control (if not w/ autosteer engaged). On the way there and back to Garfield, we must have experienced 5-10 AEB events where the traffic aware cruise control thought that the hard shadows from trucks were actually objects in our lane. This is a horrible and dangerous design flaw. Why are we not allowed to go back to dumb cruise control like we used to have where it doesn't cause an accident risk due to the possibility of a rear impact from another vehicle? In one of these events there was a truck behind us, and my 70-year-old mother had no clue how to protect us from being rear ended. We desperately need an option to disable TACC at the...

Car randomly auto braked at night while on cruise control (45 mph). Car turning across traffic was roughly 200 feet away and well out of potential collision range. Also, car won't auto break when there is an actual obstacle in front. Could drive the car into a wall (believe me, I've verified this).

This is my third report for the same phantom braking issue I drove approximately 250 miles today and had three episodes one while passing a 18 wheeler he was on the right and fully in his own lane it braked forcefully. And two episodes with no objects or any explanations why it applied the brakes hard while traveling at 78 mph once with a car following witch caused me great concern. Side note I gave up using it on two lane undivided roads any oncoming large truck or RV triggers braking.

I have experienced multiple situations where my 2022 Tesla Model 3 has issues with the automatic emergency braking feature, which causes the car to slam on the brakes unnecessarily while operating in the autopilot mode. Generally, I've seen this the most on 2 lane roads, especially when large vehicles (semi trucks, etc) are in the opposing lane. In some cases, the car will brake when there are no cars in the opposing lane. My concern is that the cars traveling behind me may not have the reaction time to brake, due to not expecting my car to brake in front of them.

This has happened on a couple of different occasions but the one thing that has been the same is it has happened while utilizing the adaptive cruise control system. These incidents come out of nowhere and can be dangerous and cause an accident luckily we have not had that misfortune. While driving on the highway with adaptive cruise control enabled, the vehicle has suddenly and without warning activated the emergency braking. The first time this occurred the assumption was that it must have picked up something on the road because it only lasted for a brief moment, it slowed down the vehicle by 10-15 mph. Throughout this trip, adaptive cruise control was used and it didn't occur in that manner again. What is more alarming are the next couple of incidents which abruptly slowed the vehicle down by 30-35 mph this was very unsettling, luckily no one was behind the...

Multiple times while driving using adaptive cruise control while approaching a semi(both oncoming and overtaking) the car will slam on the brakes(phantom braking).

On a four-lane divided highway and again on a two-lane road my Tesla 3 long range AWD phantom braked for no apparent reason several times over a 145 mile trip while on cruise control and/or on auto pilot . On the two-lane portion of the trip I assumed the braking occurred because of shadows on the road. On the four-lane highway it braked for no reason. If someone had been closely following me, I am sure a serious collision would have occurred. I will not use either cruise control or autopilot until a fix is made. This Tesla on cruise control makes for a dangerous driving situation.

While using adaptive cruise control or the autopilot systems, the car will unexpectedly brake very hard (dropping speed anywhere from 5-20 mph). This can cause a safety issue due to other cars behind that aren’t prepared for a car to randomly hit the brakes and drop up to 20mph quickly. The problem is easily reproducible by using the systems while driving anywhere. Complaints and requests to the manufacturer have gone unfixed and brushed off as not a concern. This happens every single time I use cruise control, not just the date I had to select for the incident.

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.

I would like to add my voice to those complaining about the phantom braking problem in recentlly built Teslas. On more than one occasion, the car has slammed on the brakes, in broad daylight with good visibility, FOR NO GOOD REASON. At the very least, Tesla should be compelled to add plain-vanilla cruise control that permits the driver to switch off any traffic-aware assistance features. This problem is ongoing and occurs nearly every time I attempt to use the traffic-aware cruise control. The problem makes this feature too dangerous to use.

While using “Traffic-Aware Cruise Control” the car regularly sounds an alert and breaks rapidly in preparation for a forward collision despite no such danger existing. Most often this occurs on a two-lane highway when a large van or semi-truck is traveling in the opposite direction; in its own lane, nonetheless. This feature is marked as “beta” but there is no standard cruise control option. This issue can be easily reproduced and happens multiple times on any given day when said circumstances exist. Tesla service advisors have told me the only fix is to not use the feature. I am scared the sudden breaking may cause whiplash, a rear end collision, or other danger presented by sudden unnecessary breaking. When using the additional Autopilot feature, “Autosteer,” the incidents seem to happen even more frequently and invoke a slight swerve right - away from the vehicle in question. This could make it...

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.

Phantom braking issue. Usually occurs on two lane roads, sometimes there is a vehicle in the opposite lane, other times there is nothing in front of the vehicle in either lane. I have reported to Tesla, they say they’re aware but have no solution. I have kept a log of when it happens since the first time I reported it to Tesla and was told there is no solution. I commute 128 miles a day and the below log shows it happens on daily basis multiple times a day. 1/5/2022 5:32pm 1/5/2022 5:35pm (multiple times) cruise set at 65, speed got down to 45 1/5/2022 6:30pm 1/6/2023 5:59pm 1/6/2023 6:01 1/6/2022 6:33pm 1/6/2022 6:34pm 1/6/2022 6:37pm 1/10/2022 6:37am 1/10/2022 5:11pm 1/12/2021 7am 1/12/2022 5:49pm 1/12/2022 5:50pm 1/12/2022 5:53pm 1/12/2022 5:55pm 1/13/2022 6:13am 1/13/2022 6:15am 1/13/2022 6:16am 1/13/2022 6:18am 1/13/2022 6:21am 1/13/2022 6:09pm 55 to 38 1/13/2022 6:11 pm 55 to...

on 2-3-2022 on a 200-mile day trip I had two false braking events one while passing a large truck on a divided AZ Hwy 260 and one for no notable reason what's so ever on the same Hwy. I do not have FSD just autopilot this is my second compliant to NHTSA thank you. Mike

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.

Vehicle frequently brakes hard to prevent a collision with an object that does not exist. Also known as phantom breaking that is a commonly known issues with Teslas autopilot.

Cruise control is completely unusable on two lane roads. Automatic braking ensues every single time a car is in the opposite lane. Sometimes it only slows 5-10 mph but other times the car gives the warning for an imminent collision and tries to brake to zero. This is exceedingly dangerous on the highway when other cars are behind me. It generally functions fairly well on the interstate but it does happen occasionally there as well.

Traffic aware cruise control is dangerous to use. Automatically slams on brakes on 2 lane roads with large vehicles in oncoming lane. Brakes at the top of any sort of hill, brakes for shadows of overpasses on the highway. System is dangerous and has caused several situations where I would have been rear ended on 2 lane roads and larger highways. Recent road trip had almost a dozen phantom braking events on a one hour drive on a straight 2 lane road during the day.

The TACC (traffic aware cruise control) applies sudden, hard braking especially on two lane roads and almost always when meeting a large truck (semi-tractor trailer). This is commonly referred to as “Phantom Braking“. Drivers should be allowed to disable automatic braking while using cruise control on two lane roads. It is very dangerous in that it may cause a rear end collision. The cruise control as currently implemented in Teslas is unusable and without a doubt a safety hazard. I have experienced phantom braking events every time I have used cruise control on a two lane road. It will hard brake 9 out of 10 times it meets a large truck and sometimes when meeting small cars.

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.

Our Tesla is experiencing a Phantom Braking that appears to be a known issue. We drove the car from eastern KS to western CO and experienced multiple occurrences (more that 10) of unexpected braking while using either the adaptive cruise control or the auto pilot feature. The car would dramatically slow from 75 to perhaps 65 and then accelerate back to 75. My wife also takes the car to work on a 20 mile commute and she has also experienced this. I have not discussed this with Tesla Service yet, but have read many posts about this and that we should report. So....here it is!

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”.

I received my 2022 Tesla Dec. 3, 2021. I have experienced approx. 100 phantom braking incidents in roughy 3,000 mi. Driving. The system causes a loud alert and extreme braking which is extremely concerning while driving. This has happened in all conditions (daytime sunny, cloudy, night, etc.). Several camera warnings though I have cleaned them and alerts still happen. It happens on 2-lane roads more often than multi-lane highway. Happens at residential and highway speeds. The extreme braking could easily cause rear end collisions if traffic were close. As a driver the abrupt alerts and braking could cause driver errors. This is a “safety” feature which is extremely disruptive to drivers is in fact a safety issue in my opinion. The data below is the most recent incident and it happened 3-5 times in a 300 mile drive. Tesla Service cancelled an appointment to look at my car. In a...

Issue is consistent on 2 way lane roads but sometimes occurs on Highway roads going in the same direction. Whenever I travel with autopilot or cruise control if there is a semi-truck on the opposite lane driving towards me the car will slam on the brakes for no reason. This has also happened a few times on the highway when passing a semi-truck on the same flow of traffic as myself. This has not only terrified myself but also my family and other passengers. It makes this feature almost unusable.

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.

On a recent road trip while driving on highway 70 in CO and UT at speeds of around 70mph with Autopilot or Cruise Control engaged, the car phantom braked multiple times in response to nonexistent hazards on the road. Fortunately there were no cars nearby in both instances, as I am positive we would have gotten rear-ended in both situations (the car braked to around 40mph). These were both really scary scenarios and undermined my trust in those systems in the car, I have been hesitant to use them since

Autopilot and Traffic Aware Cruise Control systems are basically unusable on two lane highways. Almost every vehicle that passes on the opposite side of the road triggers an alarm, disengages Autopilot/TACC, and results in an abrupt, jarring deceleration. This occurred 10 times in a 160 mile trip, but would have happened many more times if I had not given up trying to use either system. Holding my foot on the accelerator for such a long drive was inconvenient, and the repeated sudden slow downs resulted in a strained, tired neck. It seems unethical for a $60,000 vehicle to lack basic cruise control capabilities.

The autopilot feature which keeps the car in it's lane and speeds up or brakes the vehicle based on its surroundings is not functioning properly. It slams on the brakes whenever a semi-truck or large vehicle is driving in the opposite lane on a two-lane road. Especially if there is a bend in the road. It thinks that a forward collision is going to take place.

Phantom braking, almost caused a car to rear end me. This was on a straight two lane road a tractor trailer was coming the other way. This has also happened on a right hand curve with smaller auto where the software thinks I'm going to run into the car even though I'm turning right into the curve. Very dangerous. Same thing happens with the forward collision warning.

When the ADAS is active, during normal driving on a two-lane highway, where there is never any question of an obstruction in front of the car, the car unexpectedly and violently brakes; often the collision warning alarm sounds. This usually happens when the car meets traffic in the oncoming lane, but sometimes there's nothing else at all on the road. This is a new car (since January) and it has happened ever since I first used the ADAS. For example, last night, on a trip of about 50 miles it happened at least thirty times, nearly every time I met an oncoming vehicle of any size. Service personnel tell me this is normal behavior and they cannot do anything about it! The system is supposed to have switches to turn off the collision warming and braking so that it can be used as a normal cruise control, but setting the...

The car brakes SEVERELY on two lane highways when passing another car. Mainly occurs when passing semi trucks. It is going to get someone rear ended if this is not fixed. The cruise control is not usable.

When i drive on highway, it out blue slam brake several time i am not sure what trigger it. it was out blue from 70 mph to 50-60mph. i don't see anything around car to trigger phantom braking or brake. also on one lane highway, when semi truck or some car/trucks pass by me it slam really hard few time from 60 mph to 30 mph instant, some car almost hit my rear because of instant slam brake. I had to brake quick to undo it. it happen on cruise control only, also happen during auto pilot. the road was fine, other vechile wasn't going toward me.

Sunday, January 2nd, on the way back from Vegas back to Sacramento, on the highway with Lane assist driving, the car suddenly braked going from 70+ miles to almost a complete halt. I was able to steer it into the oncoming lane to avoid the pick up truck from hitting us from behind. The braking system again slowed the car down significantly a few more times on this trip and wee have not used this feature since. Car was bought on December 26th and we are fairly new owners of a Tesla.

While driving on an undivided highway at night using either traffic aware cruise control or autosteer, about every minute the car would aggressively decelerate up to 15mph. Every time a car would pass in the other direction, the deceleration would be abrupt and would slow to ~10mph below the speed limit. This occurred at least 3 times within a ~7 minute window. The road was straight, unlit, with a 50mph speed limit, and was sufficiently wide to safely pass oncoming cars. Random deceleration with no oncoming cars would be less severe but frequent. I contacted Tesla about this and they confirmed these occurrences but stated it was in response to a curve in the road or a vehicle being detected. They claimed the system performed appropriately. Despite being alert, these decelerations are startling in the absence of visible explanation to the driver. If I was being tailgated, a rear end...

On multiple occasions, my car has slammed on the brakes while using adaptive cruise control when nothing is in front of my car. It’s concerning because drivers behind me have almost rear-ended me and have gotten road rage at me because they think that I am brake checking them.

The car on a day basis exhibits random braking incidents when utilizing traffic aware cruise control (TACC). These have happened since the car was new (now has over 2,500mi) and can range from mild to severe. All of them happen without an obstacle ahead. Some times it seems the vehicle reacts to shadows from trees or larger structures, other times there's no obvious reason behind the reaction. The braking happens both on interstate highways as well as county two and four lane roads, and isn't related to elevation change or curves (happens straight and level). Several of these instances have been close to causing accidents due to traffic behind me getting caught off guard, which is usually followed by some sort of road-rage-like reaction. I no longer use the system when there's any traffic behind me due to the fear of getting rear-ended. I have recalibrated the cameras 3 times...

Driving on two lane road with oncoming semi truck traffic causes adaptive cruise control to abruptly apply brakes. As this has happened numerous times, I called Tesla who advised me to not use adaptive cruise control. I do most of my driving on two lane roads over long distances to shop or see a doctor, etc. Not having ANY cruise control is better than causing an accident, but why cant Tesla program a simple non-adaptive cruise control?

On 1/24/22: 9:11 am eastbound Redden Road east of Bridgeville, DE. This is flat terrain with mostly open fields on east side of the road. On a straight Regular 2 lane road, center yellow strips and white edging. West bound truck triggered braking and swerve to left. 9:14 Another truck and same circumstances further east and same result. Turned off steering assist and cruise control. 10:42 westbound on Redden Road roughly same area. Truck eastbound. Slight braking 150 yards in front of me then brakes slammed on while passing each other. Braking reduced speed by 10 mph or more and swerve to right. Hard braking and a swerve to the right for no reason. Anyone behind me would have hit me. Basically I have to make sure road behind me is completely clear before turning cruise control or auto steer on! Anyone within 5 car lengths would hit me. Not...

Phantom braking in city and highway with no obstacle in vehicle path. Sudden and strong emergency braking enough to cause a rear end collision if being followed. Very scarry in one 700 mile road trip we had 11 such occurrences . Thank you for your help. Mike

Dangerous or phantom braking of vehicle on two lane road at highway speed.

I took delivery of my Tesla Model 3 in mid December and have have driven approximately 2,000 miles, almost all highway commute miles. I have had horrible experiences with the Autopilot cruise control slamming on the brakes for no apparent reason. Nothing in front of the vehicle, sometimes nothing around the vehicle at all. Behavior is sometimes a quick deceleration of 10 mph or so; however, in some cases FULL brake is applied, coupled with an audible collision warming. Again, these things are happening with NOTHING present in front of my vehicle, and sometimes with nothing around me at all. During my daily commutes, I experience, on average, 5 to 10 instances of this unsafe slowing/stopping procedure. In one instance, the vehicle decelerated from 64mph down to 37mph, for no reason, with a line of other vehicles following me. We narrowly avoided a multi-vehicle collision, caused by a completely unnecessary...

Traffic-aware cruise control unexpectedly decelerated and/or activated collision warnings and automatic braking approximately 20 times during a 300 mile, 5 hour drive. All incidents occurred on undivided highways and state roads. This unexpected braking reduces speed by 10 to 30 miles per hour on 60 mile per hour roads. This braking issue greatly increases risk of accident, specifically if another vehicle was following too closely. Braking events occur sporadically, usually attributed to large vehicles driving well within the opposite lane. Some events happened for no reason. Occurrence of unexpected braking is higher at night. This vehicle has been inspected by Tesla in the past due to this same issue and the cruise control and autopilot system was confirmed by technicians to by working properly. The ability to disable adaptive cruise control to standard “dumb” cruise control may solve this issue. This issue instills no confidence in Tesla’s so-called “full self-driving...

The cruise control and 'autopilot' features will panic brake when oncoming traffic passes car. It is more common on two lane highways. There are no overrides and the issue occurs in all modes of cruise control. Through research on forums, this is an issue with all Tesla vehicles model year 2017+ The car brakes hard, enough to lock passenger seatbelts. Sudden hard braking with no reason can cause a rear end collision or loss of traction in inclement weather. I have notified the manufacturer of the issue, their suggestion is to recalibrate the cameras and reset the on board computer. Neither has solved the issue No warning lamps, no symptoms.

Car brakes randomly when using traffic aware cruise control. Dozens of events every hour of driving, some of which caused the car to brake to the point of losing traction.

When on adaptive cruise control, random and sometimes severe automatic braking incidents occur when no obstacles exist in front of the car. It is as if the car is getting confused as towards what is ahead, and frequently applies the brakes as if it was going to crash into something. This is always unexpected, and requires driver intervention to correct/override.
