Automatic Emergency Braking problems of the 2022 Tesla Model 3 - part 1

While at a red light, my car was stopped with Tesla full self-driving (fsd) on. When the car in front of me nudged forward, my car, still in fsd , accelerated and drove into the car in front. Looking at the event report of my car, the automatic emergency break did engage but too late. This means the sensors in front failed to recognize the vehicle ahead.

Tesla m3 rwd 2022 - 79750k miles. Touchscreen keep restarting throughout the day , in the morning when I am backing out of the garage, while I am driving, while I parked. It is dangerous specially while I am backing out of garage, car will stop sometime, because whole system reboots. I have no visibility I have to wait till its finish restarting. Tesla's main computer handles everything in the car, a/c, turn signals, speedometer, backup cameras, forward collision warning and many more necessary function of the car. Tesla service center diagnose stats "the cause was identified as kernel panics detected in the system. The internal memory of the car computer is corrupt and will not allow enough data transfer and causing the computer to reboot to clear space" they suggested to replace the computer and its a out of warranty fix, since I drove 79k miles. This is a crucial of the car and it should not fail in 3 years, driving 79k in California is not unusual, Tesla service also blamed that we didn't extended our warranty after 50k. We couldn't find any correspondence from Tesla on service app or email regrading warranty extension. $3000 to replace a computer is a very high price.

While traveling at approximately 70 miles per hour on an interstate, the vehicle's automatic emergency braking system engaged multiple times in rapid succession—approximately five separate braking events. Each time, the system falsely detected an obstacle, which it appeared to interpret as a person in front of the vehicle. In reality, there was nothing on the road; the system was reacting to a roof-mounted strap that was fluttering slightly in view of the forward sensors. These false positives caused the vehicle to brake suddenly and forcefully, creating a highly dangerous situation for vehicles behind me. Multiple drivers were forced to swerve to avoid a collision. Thankfully, no crash occurred, but the repeated unexpected braking posed a serious risk to my safety and the safety of others on the highway. Additionally, I had previously disabled the automatic emergency braking feature in the vehicle's settings. However, I later discovered that this system reactivates by default every time the vehicle is restarted. There is currently no option to permanently disable this feature, meaning drivers must manually turn it off for each individual trip, which is not clearly communicated by the system. This issue has not yet been inspected by the manufacturer or a dealer. No warning lights or error messages appeared before or during the braking events.

When the vehicle is set to regenerative braking mode, lifting off the accelerator pedal causes the car to decelerate significantly. However, in many cases, the brake lights do not illuminate during this process. This could potentially create a safety risk, as drivers behind may not realize the car is slowing down and may not respond in time. Tesla.

I'm not quite sure what component was affected, some module of some sort got water in or near it that wasn't supposed to. It is available for inspection. Yes my safety and others was out at risk. Yes the problem was fixed by service center supposedly. Yes the car has been inspected by the manufacturer. There were no warnings. What happened was on 12/29 I was driving the car and out of absolutely nowhere a bunch of warnings came up including loss of abs, any and all safety features. And more importantly lost usage of brakes almost entirely when car came to a stop it was grinding and shakey. This problem all arises due to Teslas negligence when it came to installing a new windshield on the vehicle. As stated in messages below, they made a mistake while installing my windshield that caused this major issue to arise. They have offered nothing as a solution but saying that their error is supposedly fixed.

Tesla needs to be required to implement trailer mode to all Model 3/y vehicles (not just those equipped with a tow hitch from the factory) because the basic autopilot and existing safety software does not correctly identify when the vehicle is towing a trailer. Legal aftermarket tow hitch installations exist for small trailers, such as u-haul trailer. However Tesla does not recognize these aftermarket installs. And Tesla needs to be required to add the required trailer software mode for vehicles with aftermarket hitches to provide the required safety software when towing. It is needed because of the cars emergency braking, collision avoidance, navigation, and autopilot modes need to know that a trailer is connected so that the vehicle software does not make an unsafe maneuver depending on the driving situation/condition.

Hi. My issue is partly related to case pe-22-002 and may also contribute to it as well. I will forward my dash-cam videos (the false detection of cars in-front of me for 63. 5% of that drive is included here) to your email as support for the investigations. I have been noticing warnings that a car is in the lane I am changing into when there is no car present. This has happened several times, despite the camera showing no cars and checking for myself showed no cars. The first time it happened, it scared me so bad I jerked back into my lane and could have lost control of being safely in the lane. I filed a service request and was told it would cost me an est. $195. 00 to have them look at it, but they said they think it is software related and tried to say they don't deal with software issues. It has experienced many occasions of decelerating for no cause when using the full self driving, autopilot and cruise control. It would cause me to have to disengage them as I felt it was effecting my distance efficiency. I found a new issue last night that caused concern. We have been getting high reports of following too closely, so I drove from plainview, TX to amarillo, TX in complete control myself while driving 100% perfectly and it reported that it claimed 63. 5% of that drive was "following to closely" when in-fact any time a vehicle was in-front of me by (I think) 30 car lengths, I changed into the other lane where the was no vehicles in the lane at all. It is my personal opinion that it is a combination of the cameras not being infrared and not seeing well enough in low light situations, and the software unable to tell the difference between darkness/shadows and objects that should be avoided. These false alerts occur more for me in low light conditions, but the unneeded deceleration has occurred in all conditions.

Traveling on i35 south, approx 70 -75 mph. Using adaptive cruise control/enhanced auto pilot. No vehicles present within a mile of my vehicle. Braking spontaneously engaged, reducing speed to 40mph within seconds. If a vehicle were behind me they would have absolutely collided. I've not filed a report with Tesla. Vehicle did not display any warning, or any other sort of indication that a malfunction had occurred. The problem has not been reproduced by me, however an internet search returns multiple complaints of these exact symptoms.

Car slammed on the brakes on its own while the auto steer function was being used going 80mph. If someone was behind me they would’ve rear ended me.

Something occurred with the steering, automatic braking, or lane keeping assistance on 01/10/2024 at approximately 6:35am while I was driving my 2022 Tesla Model 3 long range north in the carpool lane just south of the 106th off ramp in sandy utah. The roads were a little slick so was proceeding cautiously at around 65 mph when the car turned to the left slightly, then immediately to the right, which caused it to do a 180 degree turn in the same lane, I wasn't sure what was going on as the car felt like it was driving itself. Before I knew what was happening, the car then veered to the east across three lanes of traffic while driving backwards, it then stopped just as it was struck in front of the wheel on the front drivers side by a two trailer semi-truck which spun the car around. Luckily I was conscious so could slowly limp across the last couple lanes to the right side of the road where I called 911. I've driven all kinds of cars in all kinds of conditions and in many countries in the nearly 32 years I've been a licensed driver and have never lost control of a vehicle, I'm sure the steering or lane assist was trying to intervene so must've somehow inadvertently caused the crash! it's only through the grace of god that I'm still alive to tell about it! also, none of the airbags went off even though the impact from the semi was very jarring!.

Driving on the freeway 70mph on cruise control. Not auto pilot. No one around us and no warning. Suddenly car applied brakes on its own and dramatically slowed. Good thing there was no one behind us or else there would have been an accident and we would have been badly injured. Monday Jan 1 2024 1:35pm.

Please help phantom braking is getting worse.

I was in the carpool lane when traffic came to a complete stop. I pressed on the brakes but they were heavy as if I was not able to press it down all the way. There was no information prior to the accident from the Tesla trying to warn me about an incoming collision. It wasn’t until after the accident the Tesla acknowledged that there was damage done to the car. Prior to the accident there was a service required for the front passenger safety restraints. This accident could have been much worse as I tried to swerve out of the way to avoid traffic but wasn’t able to make it back in time.

Car brakes hard on cruise control when no other cars are around.

The contact owns a 2022 Tesla Model 3. The contact stated while driving 75-78 mph with the cruise control activated, the vehicle experienced phantom braking. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 13,300.

My car was purchased Aug 2022. In Nov. 2022 we took a short trip. I believe 5 or 6 times the car breaked for no reason. I believe it is called phantom breaking. One or two times it was a hard break that I believe could cause an accident if someone was behind me, or the wrong person driving. I was sudden and hard in those two situations. I took the car in and after they drove it two miles they told me there were no issues. Then in June 2023 we went on a long trip. I do not use autopilot, this is only cruise control. On this trip probably between 35 to 45 times we experienced the same issues. At least 5 times they were hard breaks and could cause an accident. I again opened a service visit to Tesla. Again, they drove the car 5 miles and claimed there is nothing wrong. I did not accept this answer and asked for the gm. Finally after demaing this for 20 or so minutes an man came and said he was the manager. He also argued in the beginning but when I told him I have found accidents caused by this he finally admitted that it was something called "phantom breaking" and that that it should be fixed very soon with an update. So then again, in August my wife and I went on another trip. It still is happening and probably 6 or 7 times this occurred. It seems to mostly be on smaller 2 lane highways and occurs usually when there are no cars, trucks, or anything nearby. But all it would take is a tailgater to cause a wreck. In August when we returned I made another warranty appointment her in las vegas and immediately they cancelled the visit on my app. They are lying about what is occurring and telling me that it is usually when I am following too close or some garbage like that, which is absolutely not true. I just made another appt today but I am sure they will cancel it. What do I do. I really want to go through nevada lemon law at this point. My name is dane warren and my phone is 702-444-5644. Below I am putting in the most recent incident and mileage then. Happens many time.

While driving on freeway with adaptive cruise control engaged, the vehicle suddenly slammed on the brakes with the wheels initially locking up (there was an audible screech from the tires). There was no traffic obstacle that would have suggested that there was a reason to do this. It was daytime and the weather was clear. I was able to immediately take control of the car and re-accelerate to prevent vehicles behind me from rear-ending me.

On 19 July 2023 at approximately 4am in the morning, while with my wife traveling north on I-95, I was driving approximately 77 mph and my 2022 Tesla Model 3 slammed on the brakes. I had several cars directly behind me that had to slam on brakes and perform other evasive driving maneuvers as well. Luckily my reaction time was quick enough for me to slam on the accelertor to avoid a very serious wreck and pile up. This is the 3rd time this has happened but thankfully the first 2 times I did not have traffic directly behind me. Although I paid an extra $6000 for the enhanced auto pilot, I do not use it, as I am now scared to death of this car at highway speeds. On the night/morning of 19 July, I was on just regular cruise control. The very next day (20 July) I applied for an appointment with the local Tesla service center here in the richmond va area. After a couple days, and I had not taken the car in yet, Tesla sent me a message and informed "that I am not to bring the car in. " I have not heard from them since then. . . And today is 5 August 2023. Respectfully request that you weigh in to either get me a refund for this car, or in some way restore my confidence in it. I am scared to ever put this car on the highway again. Thank you.

I was driving my 2022 Tesla Model 3 long range. This car does not have autopilot (because we do not trust that technology). We were traveling eastbound on I-8 just east of exit 61 from san diego to arizona on Sunday July 16 at about 2:30pm. The weather conditions were not an issue; it was sunny and warm. I was in the left lane doing 77mph with the cruise control on. I had passed a vehicle in the right lane and it was now maybe 500 feet behind us, still in the right lane. Suddenly, the Tesla Model 3 braked hard for no reason. The car braked so hard that the tires were starting to squeal. We were well inside the lane (had not drifted to either side). There were no obstacles in front of us. There was no discoloration on the highway from any repair or car fire. The road was completely visible. The car's speed had dropped from 77mph to about 57mph before I could press on the gas to resume normal driving. Had there been a car behind us, it's possible we could've been hit from behind. The car in the right lane did wind up passing us and I'm pretty sure they thought our driving was dangerous -- borderline insane. There were no warning sounds, no alerts on the monitor. It was completely random, completely sudden and completely dangerous. The car did this 2 more times before I disengaged the cruise control for the rest of the trip. I do not have a dashcam recording of this incident, but I do have one of a similar behavior from the car a few days earlier on July 13. It's hard to tell from the video exactly where it happens.

While using cruise control on an interstate road trip, the emergency braking system repeatedly caused the vehicle to slow excessively to where I was almost rear ended. This occurred approximately 15 times over a period of 3 hours. While traveling at 75 mph, the vehicle almost came to a complete stop on the interstate and almost caused accidents. There was no object in front of me or vehicle that should have caused the braking system to engage. Tesla owners call this “phantom braking” and after experiencing it so many times while on my road trip, I believe this is a very serious issue that needs to be investigated further. I do not feel safe using the cruise control any longer because of this issue.

We drove from colorado to minnesota and the car would phantom break while using cruise control. This happened about a dozen times during the trip. It would happen on an open road with no cars around. Very dangerous.

Driving at speed limit (70mph) on interstate 5. Was using cruise control. On 5 occasions, driving n, then s 4 days later, car braked suddenly with no obstacle or vehicle within 50 yards.

My car engaged the automatic emergency braking (aeb) when the car in front of me lightly tapped on their brakes-- when the aeb engaged, my car come to a complete stop. . . I tried to accelerate to prevent being rear ended, but my accelerator was disabled and I had no control of my car. . . Nearly causing me to get rear ended and probably causing a 5+ car collision. Many Tesla drivers have experienced this, and it is absolutely terrifying and needs serious attention because lives are absolutely endangered due to this, and Tesla will not take responsibility, nor have they acknowledged the problem, at all. I've had this happen several times in the last week and I am just waiting to get in an accident at this point. This is unacceptable.

On multiple occasions (100+) during a 4,000 mile road trip, (may 7-26, 2023) this vehicle slammed on its brakes while driving down the highway while using the adaptive cruise control feature. Speed reduction was up to 25 mph from highway speeds of 65 - 80 mph. This braking was quite dramatic, just short of locking the brakes up. Traffic conditions varied from very light (no vehicles in sight) to moderate traffic (vehicles in front, in rear and/or to the side). Weather was mostly clear, roads were mostly in good shape, there were no animals, people or other non-vehicle obstacles noted. Several instances were lodged in the vehicles "bug report" functionality, but not all, so Tesla should have a pretty good record of the status of the vehicle when several instances occurred. On more than one occasion we were very close to being rear ended because of this phantom braking. In contact with a Tesla service center, we were told this is a known issue but no fix had been found.

While driving on the highway at highway speeds, our Tesla Model 3 frequently will perform a phantom braking action, presumably due to incorrectly sensing a collision. Thankfully, so far the traffic has been light on the freeways. Otherwise, this could’ve easily caused a wreck. This has happened to us approximately 20 times in the past two days. We ensured the sensors are free of any dirt.

Phantom braking of vehicle consistently around: 1. Emergency vehicles when driving in lane next to emergency vehicles flashing light. 2. Digital maintenance signs set and flashing messages on side of road. (consistently when I pass a particular sign on a particular highway).

Adaptive cruise control fails. Repeated phantom braking on the highway. Would cause severe high speed accidents if there was traffic, luckily there was not. Not yet. Not yet. No. First appeared on my first long (5+ hr) road trip and brakes were applied jarringly for no reason, braking from 80mph down to 55 before I could turn the cruise control off. Repeated this more than a dozen times on the highway.

I was driving my car north on i15. Suddenly the car applied full breaks when there was no objects on the road. I could no longer control the car. Even when my foot was on the accelerator the car automatically depressed the break pedal. Luckily there was no vehicle behind me. I was also fortunate that we were going on a straight section of road. If this happened mid turn I would have completely lost control. These cars are a danger to society. It is impossible to drive them safely when they take control away from the driver.

While driving on the highway on a clear day using what I call cruise control that also adapts to the speed of vehicles in front of my vehicle, as well as to extreme weather conditions, with no other vehicles around me, the car randomly decided to apply the brakes without provocation which slowed the vehicle from the setting of 74 mph to 49 mph before I could react and correct the aberrant braking. This is the 4th time this has happened in this vehicle. Previous incidents occurred in heavier traffic, so I suspected the aberrant breaking was an overcorrection relative to the other vehicles around me. After this most recent occurrence, I am confident there was no other reason for the car to suddenly brake other than due to a fault with the car.

While driving across the nevada and utah deserts, while on cruise control, traveling at 80 mph we experienced 7 phantom braking. There were no vehicles or obstructions in sight and it was on straight stretches of road. We are no longer using cruise control due to the danger of possibly causing an accident.

Our 2022 Tesla Model 3 has "phantom braked" three times on the highway. During each episode, the vehicle slowed from 75mph to 45mph in about half a second - with no vehicle or obstruction in front of us. This was a 4-lane highway all three times. If a car was behind us, it likely would have collided with us. No precipitation, the car was clean and cameras clear. I took the car to the latham service center at 326 bold niskayuna road near albany, new york, to have the sensors and car checked. The tech took the car for a 10-minute drive, didn't experience phantom braking, and said that since he "could not duplicate the concern" no repairs were needed. After several messages expressing concern that this did indeed need to be fixed, neither the owners scott and carolyne nor the tech responded.

With the autopilot engaged, on the freeway, and at freeway speeds, the car will automatically brake without reason and without any traffic in front of the car. In a stretch of 100 miles, the car did this 8 times. The car even "phantom brakes" on regular cruise control. This is not only alarming but dangerous! had the road been wet, or slick, we could have easily crashed! this malfunction needs immediate attention! thank you, steve & liza starr.

During normal operation vehicle suddenly engages braking system l. This has nearly caused 2 accidents. Tesla insists there is no fault with the car.

The car suddenly braked for no good reason nearly caused an accident.

Constant phantom breaking at interstate speeds. Tesla insists this is not a problem.
