2021 Tesla Model 3 Complaint Log

Driving in autopilot during daylight hours (8:30am) about 70mph the vehicle suddenly braked long and hard, tires screeched when there was nothing around me or in the road. It could have caused a serious accident if anyone was behind me.

This is a complaint about Tesla using unqualified drivers to test Atopilot Beta on the public roads. Please note that the VIN of a random Model 3 Tesla has been used to enable this submission to be completed. Here is a video of a driver testing Autopilot on what is in his own words the most dangerous road in Virginia. https://www.youtube.com/watch?v=7VBhdrj1CqM He is driving hands free around sharp bends and against oncoming traffic entirely hands free but just giving the wheel a little nudge with his finger every 30 seconds to defeat the nag. At one point the car does swerve towards an oncoming car but corrects itself just in time. The driver is alert and monitoring the situation but because he does not have his hands on the wheel he is playing russian roulette with many lives. Please do not allow this madness to continue for one day longer. Elon Musk thinks this is all a joke which is why he has called it release 69. Smutty and unamusing. I will be posting a copy of this report on social media where it will be widely read. If you fail to take action there will be consequences. Thank you. I have archived this video in case the owner or Tesla decides to delete it. If that happens I will make another complaint with a link to my copy. A dummy USA address has been used to enable this submission. My true email address is used and you may contact me on this.

My Tesla will repeated and randomly brake strongly. This happens on regular streets and on the highway at speed. It’s not like slamming on the brakes with the wheels screeching. But a quick and strong deceleration and then it lets go. There has never been anything in front of me when this happens.

The screen keeps freezing while I’m driving. It freezes and after a while the screen shuts off and resets. The most dangerous situation was when while I was on the interstate between Barstow and Baker. The screen screen recently froze while driving on August 20th around 255pm

In Autopilot there has been a phantom braking problem (automatic emergency breaking due to object avoidance) since day one. It happened more than just regularly and would be uncalled for, scary, and dangerous. Ever since the update I have done that the company sent though, this has become now not just more than regularly but more than frequently and uncontrollably dangerous. It has done it around 30 times on a 9 and a half hour road trip. It has done a 20 mph slowdown from the speed limit FOR NO REASON in as fast as about two seconds frequently. The ONLY thing that has saved us from getting rear ended is due to driver diligence and pure luck of being on an open interstate because of the road trip instead of it being through the congested part of a city…where it still can happen easily.

Unexpected acceleration while driving my car at about 20 mph and making a right turn the car suddenly accelerated. Using the brake immediately worked. This has happened a few times with my car. The sudden acceleration surprised my wife and she asked what happened. The car does not have Full Self Driving installed and Autopilot had been off for several miles. There were no warning messages or chimes. T

Tesla Model 3 main computer system failure. Failure was not cause by any negligence by the operator. The vehicle was parked over night and upon attempting to operate the vehicle the following day there was no power to the screen. There were no warnings prior. The screen which displays vehicle speed, vehicle battery level, seatbelt warning indicators was inaccessible. Also as a result of the computer failure the vehicle did not emit the required pedestrian safety sound, the front and rear collision warnings were disabled, charging was not possible, the ability to disable passenger airbags in case of a child needing to be transported in the front was inaccessible, if the vehicle was operated during winter the ability to defrost the windshield would be impossible and all safety and security features were disabled. The screen/computer has been an issue for several owners as easily viewed by a simple google search. The vehicle is only a year and a half old and was purchased new. The issues that occurred from the defective computer could of easily have caused of an accident or a caused disabled pedestrian to have been hit. The computer was deemed the cause by Tesla’s service professionals.

After updating to Tesla software 2022.20.6 (and 20.7 and 20.8) sometimes the regenerative braking fails to activate when lifting your foot off the go pedal. Sometimes the car just coasts at full speed, and sometimes it almost feels as if the car continues accelerating after the pedal is lifted. This obviously creates serious safety issues -- if you are expecting your car to brake after lifting your foot off the pedal and it doesn't, you risk slamming into the car in front of you. The brake pedal still works, but a feature of EVs is one pedal driving, which has been broken.

Tesla allows owners to enroll as FSD beta testers however, the owner cannot unenroll when they request. The FSD beta is extremely dangerous and makes the use of even ACC impossible to use. I have requested to leave the beta via emailing fsdbeta@tesla.com, which an automatic response is received stating to unenroll respond to that email with your VIN and they will process the request. However, they do not process the request; I have sent dozens of email requests with no response and am still stuck in the beta software queue. I have attempted to submit service requests but the app recognizes the verbiage and blocks the submissions, stating to send the email instead. There is no other method to contact Tesla.

This is a complaint about the unacceptable fire risk that affects all Teslas due to the dangerous battery chemistry and the vulnerability to impact damage that can trigger an instantaneous fire . The VIN of a random Tesla has been used. This problem affects every Tesla. Here is a video of a test conducted by a European testing authority which shows the Tesla igniting almost immediately after a deliberate crash that only caused a minor strike to the underside. https://www.youtube.com/watch?v=QRDCKfCdh90 When NHTSA and many other testing authorities perform crash tests on Teslas they should do so with a fully charge battery that is warm from charging or from having being driven. This is a much more realistic scenario than using cold depleted batteries that are less prone to instant ignition. By comparison with a Tesla the Pinto was just a damp squib. And yet it was recalled and grounded. Please do the right thing before even more people get burned alive. Thank you

Had significant dangerous and scary Phantom breaking while driving on Highway 80 across Nevada. Seemed to be related to open highway with no vehicle visible on forward view during bright daylight. Sudden and deep breaking would occur at 75 mph or 80 mph repeatedly and with no apparent reason throughout the 12 hour drive. Was particularly pronounced when passing large semi-trucks. Would get sudden Phantom breaking just as Tesla would just get by a large truck. Could have caused serious event if another vehicle had been following. At first this just seemed inconvenient and unpredictable but in some cases seem like significant safety issue. Had to stop using system. Tried to report to Tesla but they have no way on their web site or private Tesla account to report.

While driving the rear passenger driver side glass just shattered, this seems to be a issue with a lot of Tesla 3 models. The glass has a outward bulge, nothing hit the glass. Luckily this did not result in a crash, but could have. There are a lot of people that have reported this on the internet, this is a new 2021 model still under Warrenty and Tesla refuses to repair it under warranty even though a lot of them are having the same problem.

The adaptive cruise control system consistently phantom brakes in situations where there is no traffic in front of the vehicle while cresting rolling hills. Sometimes this braking is relatively minor (<5 mph) while other times it is aggressive enough the passengers lurch forward. At the worst, this happened approximately 10 times in 30 miles while going the speed limit of 80mph.

While driving on a divided four lane interstate state highway, during daylight hours, sunny, clear, dry, minimal crosswind, the car spontaneously braked while under cruise control from approximately 75mph to 45mph. There was no oncoming traffic or mirages. Fortunately no following traffic either because they would have either struck us or run off the road. This happened three times in a very short period and we haven’t used it since.

My Tesla slowed from 70 to 50 on the freeway in under two seconds for no apparent reason while on autopilot. There was a concrete barrier a few feet away on the shoulder, which I had been driving next to for about a quarter mile before the incident. There was no other traffic within 50 yards of me.

I engaged the cruise control while driving on the highway. I let go of the accelerator and it correctly kept the speed I had requested. It warned me that the car would not break. As the car passed another car (probably a police cruiser) that was parked in the ditch separating the two directions of the highway, the car suddenly applied the breaks and decelerated substantially. A pickup truck towing a trailer that was driving behind us was forced to swerve onto the right shoulder to avoid rear-ending our car.

This incident happened last summer, 2022 but I recently read that it is happening to many other people and thought I should report it. I was driving on Hwy 71 south in the Cincinnati area with the ADAS with the cruise control and auto steering in operation. All of a sudden the brakes slammed on with me not doing anything to cause it. There were no cars behind me and I touched and released the brake pedal and it went back to a normal driving mode. I don’t believe I hit a pothole or bump on the highway. I did not report it to Tesla.

Car breaks heavily without warning or cause. No cars in front view yet applies breaks like avoiding an accident. Almost caused me to get rear ended multiple times.

While driving in Highway, Interstate or Freeway with cruise control enabled with or without autopilot the car suddenly breaks for no reason. It is a clear phantom break. It happened many times in different occasions even on the I40 with no car around in the middle of the Desert. In a couple of times a big truck was following and I was almost rear ended because this.

While traveling on interstate highways over a period of 2 days both in overcast and sunny conditions the vehicle initiated braking multiple times in cruise control only (not on autopilot). No other vehicle nor obstruction was near when this would happen.

Tesla has been phantom breaking during autopilot multiple times in a single drive and has happened on multiple drives.

This "self driving" Model 3, with FL License Plate [XXX], attempted to merge onto I95 south from an on-ramp, and very nearly caused a major accident. The vehicle had a bumper sticker on the back that said something like "please be patient, I am a self driving vehicle." The vehicle was merging from a left side on-ramp, at a VERY LOW SPEED, and crossed two lanes of interstate traffic, very erratically accelerating, then braking, then accelerating again, and then braking. My vehicle was directly in its path, and I had to brake hard, and take to the shoulder to avoid the collision. If this vehicle's trips are logged, it needs to be investigated. If it weren't for the humans paying attention, the actions of the Tesla car/driver would have caused a major accident, and most likely bodily injury or death.

Seat sensor fail and was able to drive in the middle of the intersection to make a left turn. Since the sensor fail if vechicle is driven less the 5 mph the car will go in park- very scary when in the middle trying to turn left

The contact owns a 2021 Tesla Model 3. The contact stated while reversing the vehicle from her residence at 3 mph and attempting to turn to the left, but failed to turn. The contact stated the vehicle continued to go straight and ran into a chain link fence. The contact stated no warning light was illuminated. The contact stated no one was injured nor sought medical attention but she was frightened. The contact attempted to straighten the vehicle by turning left again and drove into a railing. The contact stated the instrument cluster screen when blank after the second crash. The manufacturer had been informed of the failure. The contact towed the vehicle to local dealer and was being serviced at the moment of the call. The vehicle was not diagnosed or repaired. The failure mileage was approximately 12,297

Please note that I have used the VIN of a random Tesla Model 3 to submit this complaint since the number of the actual car is unavailable. There has been an incident on a motorway in Germany and a full video is available here. https://www.youtube.com/watch?v=oKcvLeMWp3c This is a single vehicle incident. The front RH wheel has simply fallen off. There is no other car involved. There are no air-bags deployed. How much more evidence do you require before you demand a recall? The suspensions are deadly fragile. I will make it simple for you. Watch THIS video https://www.youtube.com/watch?v=-fkpIvIeHhc Plenty more where that came from. https://www.youtube.com/watch?v=-fkpIvIeHhc Have a nice day. Keef

Car would slow down and suddenly using regenerative braking for no good reason while on Traffic-Aware Cruise Control (part of Autopilot) on very lightly traveled highways, mostly on I-80 in WY, UT, and NV. Incidents happened on 1 to 2% of every mile traveled. I have marked the date as July 3 below, but actually multiple (20 to 50 total) incidents occurred from 7/2 to 7/4, and 7/9 to 7/11. Incidents could occur whether Autosteer was engaged or not. No alarm sounded to indicate that a collision was imminent. If I didn't intervene, the car would sometimes recover almost immediately and slowed only 5 mph, but in other cases it would slow down by 20 mph within 2-3 sec before recovering. Speed limits were typically 75 to 80 mph; I was normally traveling around that speed. Although these highways have low traffic density, my biggest concern is that another car will rear-end mine if it's following too closely. My own observations: 1. The most frequent incident type seemed to occur when there were no vehicles ahead for 15 to 30 sec following distance. Prior to this, Traffic Visualization would sometimes show the next vehicle with uncertainty (flickering in and out or changing size) even though it doesn't normally show a vehicle outside of 4 to 6 sec following distance. Typically that vehicle was a semi-trailer and its appearance to myself (and probably to the cameras) changed due to lighting, details of the trailer, going over a hill, etc. 2. Less frequently, the car would slow down while passing a semi-trailer. Generally Autosteer was not engaged in these cases. 3. High crosswinds could be felt in many cases, but not all. 4. The system seemed much more reliable in areas with more traffic. I'm not sure, but I speculate is that the AI may start looking for vehicles where none exist if it can't easily see any. 5. When mentioned, 2 other Tesla drivers confirmed seeing similar behavior.

There were 3 back-to-back incidents of phantom braking. Car was in Navigate on Autopilot mode on Highway 85 somewhere near Blossom Hill and going a 65mph (posted limit) but it slowed down dramatically causing the possibility of the car being rear-ended. There was no blocking vehicle or object that should have caused it to slow down and brake. In all three incidents, I was able to assume manual control and safely speed-up again.

The contact owns a 2021 Tesla Model 3. The contact stated while driving approximately 65 MPH with the self-driving feature activated, the vehicle experienced phantom braking. There was no warning light illuminated. The contact stated that there were no other vehicles nearby in the lane. Additionally, the contact was unaware of any shadows or anything else in the lane. The contact stated that the vehicle slowed down and then resumed a higher speed. The contact stated that he disengaged the self-driving feature and manually drove the vehicle. The vehicle was not taken to a dealer or independent mechanic to be diagnosed or repaired. The contact stated that he attempted to notify the manufacturer thru the vehicle App but was unable to leave a full detailed report. The approximate failure mileage was 10,445.

Cruise control set to 75mph (speed limit) on lightly trafficked divided highway at ~5pm on June 26. Skies were overcast and temp was about 80 degrees. Car braked from 75 to about 62mph but did not disengage adaptive cruise control and neither did I by applying the brakes. There was light traffic and it did not happen while approaching an overpass which has triggered this before on two occasions. After rapid deceleration to 72, car increases speed but fluctuated in high 60s and low 70s before returning to the programmed 75. Incident lasted about five seconds in total. Once car returned to 75, I disabled cruise control for remainder of journey. This was a 45 mile journey and the issue did not surface until about 35 miles in to the journey. Because this has happened before, I was mentally prepared for it this time and wanted to see if the car would eventually stabilize back to the 75mph programmed speed. In two prior incidents in late 2021, the braking was severe and without warning so in those instances I immediately deactivated system by pressing brake pedal. The incident I report now also had no warning, good weather, no cars within about 100 yards, and no sun glare at all. Road surface was very good as it had been recently improved in 2021 so lane markers were excellent as well.

On June 18 and 23, 2022, I was driving I-5 in Washington State with adaptive cruise control engaged when, abruptly and without warning, the vehicle decelerated. I overcame the first instance by depressing the accelerator; the vehicle self-corrected in less than a second in the second instance. In both cases, there were no vehicles in the immediate vicinity to present a possible hazard. The concern is for vehicles following closely during an incident that might not react quickly enough to avoid a rear end collision. The vehicle has not been inspected by another party and no attempt has been made to reproduce the condition for another entity.

Car brakes while using adaptive speed control. In one incident the car was traveling at 71 miles per hour and braked to 25 mph. In other situations the car braked by at least 5 mph, on some situations this happened while speed control was engaged and I was traveling at 50 mph or less. In all these situations, there was not another vehicle in front of me that posed an immediate threat of collision. The adaptive self dimming headlights do not work properly while driving at night. Lights do not always dim for approaching vehicles or when approaching another vehicle from behind. On some occasions the bright lights engage when approaching other vehicles OR dim when not approaching another vehicle. Other times the light repeatedly switch from bright to dim when following other vehicles. I reported these issues to TESLA. The response was that their engineers are aware of the problenms and it is related to a firmware update and that will be coming. I worry about being struck from behind when the brake suddenly engages. I also worry that the headlight situation can cause a crash by blinding drivers.

The car will phantom brake suddenly and sometimes hard while the adaptive cruise is on. I have reported to Tesla and they say there’s nothing they have to fix right now. This is extremely dangerous and Tesla needs to focus on a fix.

What component or system failed or malfunctioned, and is it available for inspection upon request? - Cruise Control randomly slams on its brakes, no warning at all. No, it is not available upon request. How was your safety or the safety of others put at risk? - Cruise Control (Autopilot), puts my safety at risk because it can injure you if you are not anticipating the brakes being slammed, and it can put others at risk because if they aren’t following at a safe distance or not expecting the car to slam on its brakes, it can lead to an accident. Has the problem been reproduced or confirmed by a dealer or independent service center? - No. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? - No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? - No.

For no reason, the car applied significant braking while in Autopilot. There were no cars in front of me, no obstacles in the way and it was a clear, dry day. This is not the first time this has happened but it was the most significant.

The Autopilot applies the brakes for no apparent reason, when there are no other vehicles in front of it, under good driving conditions; in clear daylight, on empty roads and on straight stretches of highway. My family could have been involved in a serious rear end collision, or caused other vehicles behind me to collide, if traffic was heavy at the time the system determined it needed to apply the brakes.

When driving on the highway in adaptive cruise control, our vehicle all of a sudden breaked which slowed the car down dramatically. There was nothing around us that would have caused the car to automatically apply the breaks. This happened multiple times in a single drive on both Autopilot and Adapative Cruise Control. Luckily, no one was directly behind us when this happened so no collision was caused, but had someone been directly behind us we would have been hit. The vehicle has not been inspected by the manufacturer, insurance or police. The breaking was very random, and we had to tap the brakes to take control and hit the gas to get the car back to highway speeds. We have stopped using cruise control and autopilot after seeing this is a known issue and an investigation is ongoing. It is extremely concerning that this "phantom breaking" happens without warning and at random when there is nothing around the vehicle to cause it to apply the automatic breaking system. This is a safety issue on the road.

I had 2 phantom braking incidents one one trip today. The situation was similar- a car broken down on the shoulder. In both cases i slowed down and moved a bit left to give them room. I had cruise control on but as I braked, it came off. In both cases, once I passed the cars, the Tesla brakes hard. In one case I was almost rear ended by the guy behind me. In both cases, i was in full control of the car and was slowing down and giving way. The phantom braking occurred as I was abreast or past the hazard - in other words, too unnecessary and too late to help anyway. It scared the heck out of me - twice. The car is unsafe at any speed

While driving at 70 mph with adaptive cruise control engaged I experienced several instances of "phantom braking." The car braked hard all by itself with no driver input. This happened several times on June 2, 2022 and again on June 6, 2022.

I was driving on the freeway, North on I-5 here in Washington State, approximately 60 to 65 mph, when in autopilot the car phantom braked for no reason. The breaking was very hard, and occurred in the passing lane; this could’ve easily caused an accident but luckily did not.

When I am driving and using the cruise control (Tesla calls this Traffic Aware Cruise Control), the car will randomly brake while I am driving, sometimes very abruptly and hard, even though there is no obstacle, the road is clear, there is no weather, no danger, etc. There is no way to disable this "feature" if I do not like it so that I can use cruise control normally, the only solution is to drive it manually and not use cruise control. If somebody is behind me they almost run into me. I will provide a date below when this occured as requested, but it occurs EVERY SINGLE TIME I DRIVE THE CAR. Need to have an option to just have normal Cruise Control without the "Traffic Aware" portion. This is a REAL issue. I love my Tesla but I absolutely HATE this dangerous "feature" that DOES NOT WORK properly.

When on Autopilot (Traffic-aware cruise control), the vehicle will brake suddenly and severely when cresting a hill that the cameras in the car cannot see over, if there is no other traffic in front of the car for the Autopilot cameras to reference against. This is most notable and disturbing on inter-city freeways in the western U.S. such as eastern Oregon or Nevada, where the freeways are rolling. This behavior (braking when cresting a hill with no vehicles visible in front of the car) is quite repeatable. The vehicle is a 2021 Tesla Model 3 with "Tesla Vision," i.e. cameras only with no radar. It is not possible to turn off the "traffic aware" element of Tesla's cruise control. If the Tesla interface had a toggle to turn off "traffic aware" so that it had conventional cruise control (i.e. the vehicle will simply hold the chosen speed regardless of surroundings), that would be helpful and in many ways safer. Ideally, though, they would reprogram the Traffic Aware Cruise Control so that it can handle cresting a hill.

On a trip to Northern California, I used the "traffic-aware cruise control", and there were several episodes of sudden hard braking for NO REASON. With no vehicle ahead for 20 car-lengths, no curves, no vehicles moving into our lane from the side, we had no clue to why this jarring experience occurred. I thought it might have been caused by gentle inclines in the road ahead, but there were plenty of these that did NOT cause this violent slam of the brakes. So, I dismissed that explanation. The final time it occurred, there was no incline, no impediments of any kind. Just a clear, flat lane ahead and no vehicle to the right, plus an unusually wide shoulder to the left. Not even a center divider wall or K-rail. The car is now scheduled to be taken to Tesla on June 29, but having obtained the appointment through the app, I have no way of knowing if I must leave the car overnight, if I can get a loaner, or even if they'll call me when it's done, assuming they can fix it.

The contact owns a 2021 Tesla Model 3. The contact stated while using a self-driving mode at 50 mph, it would not stay in the lane and drive slowly into the next lane. The contact stated on April 9, 2023, while using a self-driving mode at 15 mph, a pedestrian walked into the lane and the vehicle did not detect the person and hit the pedestrian. No air bags deployed. The contact did not sustain any injuries. The pedestrian sustained an unknown fractured leg and a fractured arm and sought medical attention for his injuries. A police report was filed. The vehicle was not drivable. The vehicle was towed to a Tesla collision shop and had the front windshield replaced. The contact took the vehicle to the local dealer but was informed no failure was detected. The vehicle was not repaired and continued to experience the failure. The manufacturer had been informed of the failure. The failure mileage was 48,570.

This happens to me all the time. Especially on interstates such as I-4 in Florida. The car will suddenly brake with no warning, slowing down dramatically. For example, if driving at 80 mph the car will suddenly for no reason slam on the brakes to 50mph, almost having other cars behind me rear end me. This issue has never been dealt with by Tesla and Tesla claims it's a normal problem to have. I've never had any other car with adaptive cruise control do this.

Vehicle will engage breaks when there is no obstacle or while on a straight road when placed in cruise control.

Since purchasing my vehicle a year ago, it had has occasionally engaged the emergency braking system in situations where other cars have not been a threat or directly in front of me. This week, the system engaged when I was driving up an incline on the highway with no vehicles around me. Very disconcerting and DANGEROUS. As a result I deactivated the system. This is a flaw.

We have experienced numerous occasions of phantom braking, or sudden breaking while using the adaptive cruise control. The dealer could not find and mechanical or software problem although the issue persists. This is unsafe because the vehicles breaks suddenly and aggressively from speed without warning and when no breaking action is needed. I fear being rear ended by a following vehicle and have been reluctant to use cruise control. Warnings appear intermittently regarding camera visibility and needing cleaning the cameras have been clear when this warning appeared.

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.

My 2021 Tesla Model 3 has various issues with the auto pilot feature. When engaged the car makes sudden and abrupt stops while driving. This has happened various times while driving on the freeway when there were no obstructions present. The autopilot feature also prompts to change to the right lane, when dismissed the prompt appears again repeatedly. This is repeated throughout the drive and poses a major distraction. There was supposed to be an “over-the-air” correction but my vehicle has never received the software update.

Sudden unexpected deceleration. There was no car or obstacle in my lane and my car hit the brakes. It seems to have gotten worse with the latest firmware update. It seems like when a shiny object is on a mailbox near the side of the road the car hits the brakes. The truck behind me could have hit me and got very angry and sped around me. This is going to cause an accident if not fixed. It's happened multiple times now.
