2020 Tesla Model 3 Complaint Log

I had 2 incidents of "phantom braking" in the vehicle this past week. I was just in cruise control, and the roads were in good condition, visibility and skies were clear, there were no cars in front or behind me, and we were cruising about 70 mph. In 2 cases, the car just slowed by itself for a few seconds and then I disengaged the cruise control. In 1 other cases, the car made an abrupt braking from 70 to about 40 mph. I disengaged and then did not use cruise control any longer. I've been told by Tesla service that the car's "radar" feature was replaced/disengaged in lieu of Tesla Vision, which apparently is in "beta" phase. In any event, this should not be happening, especially in just basic cruise control under ideal road conditions.

Driving on cruise control (not autopilot), in the following conditions: on an interstate highway with all lanes in the traveling direction clear, no obstructions and no traffic to the front or to either side of the car, on a straight road with no bridge or on or off ramp in front of the car, daylight and no rain or or other participation, the car can unexpectedly and without warning aggressively brake. If the driver does not immediately regain control of the speed (by pressing the accelerator, or turning off the cruise control) the braking has caused the speed of the car to go from 75mph to 30mph. Unlike other Tesla accident avoidance features, the braking occurs with no indication that an obstruction is being avoided. I have owned the car since it was new and until Saturday 8 October 2022, the adaptive cruise control worked as expected. Since that Saturday (less than a week) the braking has occurred several times. Each time it required a sudden depress of the accelerator pedal to recover speed control of the car. The first photo I've attached shows a screengrab of the moment of one deceleration on Monday 10 October saved as a dashcam video. As you can see there is no obstruction and no other traffic around the car at the time. The second photo is a snapshot of the chat session I had with Tesla service where they claim that this behavior is caused by a curve, off ramp, a bridge, a two lane road. As you can see in the first photo, none of this is the case.

While driving on an open highway using the Tesla Auto Pilot (Adaptive Cruise Control, NOT Full Self Driving), we experienced 3 separate instances of unexpected braking. In each case, we were on flat terrain with no vehicles in front of us for hundreds of yards. The weather was sunny and warm with few clouds in the sky. We were driving westbound between 10am and 1pm at the time of the incidents. During the first incident, the vehicle began to brake sharply and violently enough to startle, awake and scare a sleeping adult passenger in the front passenger seat. From memory, the braking rapidly dropped our speed by 15-20 mph. Thinking it was a simple glitch, I attempted to re-engage the system two more times and the same type of behavior occurred each time. I drove the remaining hours of our drive without engaging Auto Pilot. After researching the issue following the drive, I learned of the "phantom braking" issue many customers have reported. We then reported the issue to Tesla and created a service appointment to check out the vehicle. Tesla responded back that the ran a full remote diagnostic and the vehicle has no hardware issues reported by any sensors and said the service appointment was unnecessary because there was nothing to look at.

The contact owns a 2020 Tesla Model 3. The contact stated while driving 75 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 made aware of the failure and informed the contact that a technician would inspect the vehicle at the residence. The failure mileage was 26,498.

Autopilot has repeatedly slowed down very quickly and suddenly on multiple occasions over the past year for no reason on a completely clear road. It’s the same “phantom braking” issue as described in this article: https://www.cbsnews.com/news/tesla-phantom-braking-nhtsa-750-complaints/

Sold car with defective parts. Scratched rocker panels that Tesla refuses to take responsibility for. Broken and rattled center console dash. Crooked front hood that the service center has not fixed. Broken driver seat that has foam missing on one side that tilts the seat and makes driving uncomfortable. The service center has not fixed these issues and the car was sold defective.

MY ROOF GLASS CRACKED FROM INSIDE OF THE GLASS THAT IS SANDWICH TO IT. THEY REPLACE THE ROOF GLASS FOR FREE. A FEW MONTHS LATER, WHEN I PULL INTO A PARKING LOT AT AN ANGLE, THE WINDSHIELD IS CRACKED FROM INSIDE OF THE GLASS JUST LIKE THE ROOF GLASS. NO DAMAGE FROM OUTISDE AND INSIDE OF THE GLASS. BUT TESLA WANT TO CHARGE ME FOR NEW WINDSHIELD.

The contact owns a 2020 Tesla Model 3. The contact stated that while reversing or driving forward, while depressing the accelerator pedal and adjusting the seat, the vehicle independently shifted to park abruptly. There were no warning lights illuminated. A software update was previously completed. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted and suggested a reboot and service on the vehicle. The approximate failure mileage was 20,000.

I was driving on a deserted highway on Interstate 395 heading from LA to Mammoth Lakes. There were no cars behind or in front of us. I first put the Tesla into Auto Steering mode, and things were fine for a while. Then I experienced "phantom braking" with no warning. The car started to brake on its own, and then I disengaged auto steer and drove manually. About 30 minutes later, I put the car into simple "cruise control" and things were fine for a while. Then again with no warning, the car started to hit the brakes. I disengaged the cruise control and took over again. In both cases, there was nothing around us. The weather was clear and sunny. This shouldn't be happening. There was a recent Tesla software update where Tesla apparently discontinued its use of 'radar" for the auto steer and is only relying on the car's cameras. I don't know if this is the cause of my recent phantom braking, but this is concerning to me as it is a safety problem especially if there were any cars behind me.

This vehicle has the phantom braking issue whether you are using adaptive cruise or autopilot, and has happened at least 15 times in the past two years. Because of the sudden braking, we almost had a collision with a semi-truck coming up behind us on I-5 heading south the last time and the driver thought I was brake-checking him, making him very angry and giving obscene gestures at us for it. We reported it to the Tesla service center, and they basically said it happens, and they disclosed it in the operator manual. That is unacceptable. This is very dangerous, and lives could be lost in the circumstance where someone is following close behind. Tesla basically is saying it can happen and there is no fix which absolutely unacceptable and this car is dangerous to drive.

Tesla software version 2022.24.8 that I currently have installed has switched off the vehicles equipped forward facing radar. I can't find any method to undo their software update, I'm unable to find a way to contact a person via their website. I've lost control of my lights and wipers when the vehicle is using Autopilot. Both of which are set to automatic leaving me the driver with absolutely no way to turn them off short of turning off Autopilot which I've paid money for. I'm unhappy that a vital safety feature that I'd paid for (radar) has been switched off by the manufacturer without any means whatsoever to turn it back on. I do not want their software overriding my decisions as the driver, radar needs to be on and I the driver need to have full/complete control over lights and wipers.

The other driver hit the rear of my tesla model 3 which cause the car accelerate fast about 40-50 miles, the brake is not working either. I can not brake or slow down the car.

Car randomly apply brakes when no obstacle present while Auto Pilot is engaged. Also gives a lot of false collision warnings.

"Phantom braking" issue. When car is in autopilot or enhanced autopilot mode (an upgrade I purchased after I bought car), will brake suddenly and firmly at high speed for no apparent reason. Until September 2022 car would very occassionally brake too easily in autopilot mode (perhaps 3 times in two years), but it was not sufficiently forceful or frequent to cause alarm. However, on 9/26/22 and 9/30/22 during daytime driving car violently braked on highway at least 6 times over approx 500 miles of driving. Fortunately, these incidents caused no damage, collision, or injury. There was little additional traffic on the road at the time. However, items in car, and two cats in carriers on back seat were thrown forward and displaced, and the incidents were very frightening. When I realized this was happening in autopilot modes, I stopped using feature completely and have not since. At 11/19/22 service appt for issue at Alhambra Tesla dealer I was told this was a "known issue" with no current solution; however, I was told that the more I used autopilot and hit accelorator during phantom braking, the faster car would "learn" not to do this. Given that taking the risk of continuing to use autopilot at all poses a serious risk of injury, I am truly shocked at the suggestion that I continue to use this feature and essentially train my car not to be dangerous. Via Tesla app I gave information and dates to Tesla prior to service appt and was told that they would attach vehicle log to file for service visit.

The car has regenerative breaking where the car is supposed to slow down when you lift your feet off the accelerator. Since a new update, some times (10%), when you lift off the accelerator the car does NOT slow down and will maintain speed. This inconsistent behavior is extremely dangerous and you don't know if the car will slow down or not. Tesla refuses to acknowledge this is an issue.

The forward collision warning censor gives an absurd number of false positives. I have Tesla insurance, and the insurance rate is HEAVILY affected by forward collision warnings. Nearly every day, one is triggered with -nothing- in front of me. I mean empty road ahead. Or, a car is about 7 car lengths ahead of me, they begin to slow down to make a turn, begin their turn, and nearly exit the lane. Without slowing down, and still 3 car lengths ahead, I get an angry forward collision warning and a major increase in insurance with -zero- risk of accident. It seems to happen most frequently at low speeds

The car has randomly braked multiple times, for no reason at all. Maybe shadows or mirages?

This vehicle has frequent episodes of phantom braking at highway speeds. No obstacles, stop lights or other vehicles in proximity

on July 19,2022, when I was driving on driveway, at less than 5 miles, I tried to stop to drop my wife and applied brake. Instead of brake, due to computer mal function, it accelerated & hit the garage door, broke the garage door, door fell on the car parked in the garage, damaged that car,and tesla automatically reversed. while reversing brake wasn't working too so I tried to put in drive & brake still was not working so to stop the car for safety, I hit the curb in my front yard All airbags were deloyed, inuring both of us. All doors were locked & we couldn't open any of them. We could open windshield. We shouted HELP and my neighbor came & open the door from outside so we could get out otherwise we both could be dead inside the car

The contact owned a 2020 Tesla Model 3. The contact stated while pulling into the driveway and depressing the brake pedal, the vehicle failed to respond, accelerated unintendedly, broke through the garage door, and crashed into the vehicle parked inside the garage. The other vehicle moved away and damaged the garage. There was no warning light illuminated. The air bags did not deploy. The contact shifted into reverse (R), pulled out of the driveway and shifted into drive (D). The brake pedal was depressed but the vehicle failed to respond. The contact stated that he hit the curb to stop the vehicle, and the vehicle stopped. The contact stated that all the air bags then deployed. The vehicle failed to unlock. The contact rolled down the windows and cried for help until the neighbors arrived and opened the vehicle from the outside. The contact sustained bruises on both arms, and the contact's wife sustained bruises on the right shoulder and on the left leg. Both the contact and his wife received medical assistance. There was no police report filed. The vehicle was towed to a third party it was sold to. The other damaged vehicle was totaled. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 9,600.

Unexpected Phantom Braking was experienced in this vehicle on a sunny day at mid day on I-30 going East through Arlington. The car was operating on Traffic Aware Cruise Control. Travelling at approx 70mph the vehicle suddenly slowed very quickly below 50 mph before I interceded to resume control of the accelerator to resume my speed before I was rear ended. This occured as I was approaching an overpass in my middle lane.

the recall NHTSA Recall Number21V-00D has NOT been fixed by Tesla on my car. I have scheduled service multiple times and they continue to deny availability of parts to repair. This is frustrating! How can this manufacturer have all the parts for nee car sales and not for a government mandated recall?? Can you do anything?? Please, advocate for me a tax paying consumer. Raul Martinez

Phantom braking: While driving down the highway for no apparent reason the car brakes and one time we had a car behind us that almost hit us. This is very dangerous and Tesla need to fix this asap. This has happened multiple times since around March 2022. The passengers in the car are slammed forward without any warning. Today was the scariest because we were almost rear ended and my 6 year old granddaughter was slammed forward. This is unacceptable.

Cars computer froze and I was stuck in cruise control. Hitting the brake would not disengage. Pressing up on the stalk would not disengage. I could manually slow/accelerate the car with the brake/accelerator but after letting off the car would continue on at that speed while everything else remains frozen. No turning signal function. I was afraid to attempt to stop the car fully as it would not disengage. Screen eventually went black and reset after what felt like forever. Functions returned to normal.

Body control module failed. Car locked my wife inside the car when the power for the entire car shut down. Managed to get her out. Car was towed by Tesla to their repair facility in Pensacola FL on 6/22/22. It has been there since with no ETA on repair, they cannot get body control modules to repair the car. This was a previously known defect (see article https://hackaday.com/2021/02/11/tesla-recalls-cars-with-emmc-failures-calls-part-a-wear-item/ ). Tesla staff in Pensacola said they had 6-7 cars at their facility with the same exact issue.

On 6/18/2022, nearly all visual based safety and convenience features of my car ceased to function randomly. I was given errors/warnings on the screen that cruise ("autopilot") control was unavailable and that automatic emergency braking was unavailable. I drove the vehicle manually to my destination, and after sitting overnight, it magically all worked again. Software on the car at the time was 2022.16.1.1. I am filing this compliant because since obtaining this vehicle in March of 2022, the "autopilot" system has been a constant area of concern. Tesla really needs to get this system working, or perhaps be forced to reduce its functionality (like just have a normal speed based cruise?) until its ready.

On or about June 15, while driving my TeslaI received a notification from my Tesla that the automatic Emergency Braking was disabled. There were also notifications that Autosteer was unavailable, and so was cruise control. I made an appointment with a Tesla repair center for repairs to the car under warranty. My initial appointment was postponed to enable remote diagnosis. On July 6 I brought my car to a Tesla repair center. After looking at my car, Tesla informed me that the car had no then current alerts or faults. They "were able to confirm this is known firmware characteristic. Tesla is working to to resolve this in a future firmware update." It's not clear to me what they are saying and whether this was a false positive from the firmware error reporting system or a transient fault that they could not reproduce. In any event, the fault reporting and the failure of Tesla to repair its firmware for a 2 and 1/2 year old car is a concern to me.

Car was stopped at a red light. All of a sudden car speeds up & was out of control despite applying brakes

Autopilot regularly will panic brake (phantom brake) it also will often randomly change the set cruise control speed from 70 to 35 or from 75 to 35. This is a dangerous system that should not be allowed on the road.

I have reported multiple times that the car suddenly brakes in the middle of the express way with no apparent reason. This issue is known as phantom braking. Tesla postponed the diagnosis of the car multiple times and I was told by the service department that the problem was going to be fixed by replacing the radars when I left the car on May 16, which they did not do. The last events of phantom braking occurred multiple times and even I continued stepping on the accelerator, the car continued to engaging with the emergency braking. This is a safety issue and the company has failed to fix it

When using the adaptive cruise control phantom breaking occurs. This is extremely dangerous because at times cruise is set to 60-75 mph and car will randomly hard brake. If someone was following me this could definitely cause an accident. It’s also so abrupt that it jolts your body forward. I have not taken the car to any service center to reproduce. There are no warnings, no indications of anything visually on the screen that the car would see to cause the breaking. There is also one spot on my route it consistently does this on. This issue has been occurring since early 2021. I take the same route daily for school drop off purposes. It’s a 45mi trip one way. The issue will consistently occur at least twice one way on the trip if I’m using the adaptive cruise system. I do not use auto pilot only the cruise.

The car exceeds the speed limit with adaptive cruise control/autopilot, despite all the available settings being set to strictly obey the speed limit. Driving on the highway in a 60mph zone enabling autopilot will set the speed to 60mph, as expected. If the speed limit increases, the car will change to the new speed limit, e.g. 70mph. Now, if the speed limit drops back down to 60, the car will NOT slow to 60, although the correct speed limit is displayed. Also happens on streets.

We were pulling our car from 5th floor of a parking garage and as the car was coming down the ramp into the 4th floor, it accelerated itself to a high speed, hit another parked car, and came to a stop hitting concrete pillar in the garage. Our car was damaged severely and all the airbags got deployed, smoke came out it. We are still in shock from the incident and it was a traumatic experience for all 4 members of our family including two of our children. It would have been catastrophic had there been another person around or if something more had happened. Our car unexpectedly accelerated and none of the warnings worked. Tesla car usually gives us warning (a shrilling beeping noise) when an unexpected obstacle, be it another car or a trash can or a human, is within a short distance of the vehicle. This warning sound comes up even when no automatic driving feature is used. But on that day, the warning sound did not come and we think the vehicle may have malfunctioned. When we searched in the internet, we found many incidents of unexpected acceleration with Tesla Model 3.When we brought our concern to the insurance, we were asked to report to NHTSA. The car is now with insurance and the manufacturer has not looked into it as we haven’t informed them yet. The car was in excellent condition and there were no warning or failure lamps on before the incident. This warrants your attention and hence we are writing this to you. Please advise us the next steps and if we need to preserve the car to retrieve any data recorded in the vehicle. For the safety of other drivers and pedestrians, this needs to be thoroughly investigated. Kindly do the needful.

The blind spot warning is non-functional, plus the camera image system is defective in low light conditions as the image displayed is obscured by the glare of the turn signals

When I signal to change lanes the side cameras show the blind spot. At night the camera is blinded by the light from the turn signal due to a fault in the camera, Tesla has a fix but want hundreds of dollars to repair.

Vehicle at least once per day automatically brakes. Phantom emergency brakes for no reason randomly when going straight on the road no objects come into obstruction for the cameras. Common Tesla problem. This needs to be fixed. It has almost caused a few accidents for me now.

Front passenger seat seat belt gives me an error saying front safety restraint system fault. Tesla says it's not a problem and will not fix it

"Phantom braking" issue is very real and very dangerous on my vehicle. Problem occurs while operating the car with Autopilot engaged such that the adaptive cruise control is in operation. Problem happens with or without also having the auto-steer function engaged. Problem is that the vehicle will suddenly, very unexpectedly slam on the brakes. This can cause the driver of the vehicle to go into panic mode and for obvious reasons is also very dangerous for vehicles that are following the malfunctioning Tesla. Sometimes, this sudden, hard braking occurs when a vehicle coming toward the Tesla makes a left turn in front of the Tesla at a VERY far away and VERY safe distance - so safe that the driver of the Tesla is caught completely off guard when the Tesla decides to slam on the brakes. And cars behind the Tesla are also caught off guard. Other times, this "phantom braking" happens for no apparent reason at all - totally out of the blue. I am now very leery to use the autopilot feature, even though that was one of the vehicles biggest selling points. I am positive that only reason I have not been rear-ended is I have quick enough reflexes that I have been able to push my foot on the accelerator quickly enough to over-ride the sudden braking before the car behind me hit me. I have called Tesla's service department about this issue. They do acknowledge the issue, although in a vague manner as if they are reluctant to fully admit how prevalent and serious the issue is. I've asked if there are any adjustments I can make to the various settings that might reduce this problem. The representatives that I spoke with had only anecdotal experiences from conversations with other customers complaining about this problem. My Tesla has several control settings which could be related to this problem. They are not well explained in the owner's manual, plus some settings appear to overlap or conflict with similarly named settings. Confusing! Many incidents, so is date is not specific.

Shift stalk also serves as fsd disengagement- to Shift into reverse with a regular car, it’s a very explicit mechanical shift with either the manual or automatic gear box. So consider this scenario where I nearly back crashed into the car behind me. In fsd, it can be disengaged either by 1) braking, (2) breaking torque with the steering wheel or (3) lifting the gear selector stick. So, I arrive at a stop light, I brake because fsd driving is producing an alarm that it came too close to the car in front of me (not me, fsd too close). Being human and not realizing that fsd disengaged when I hit the brake, a then lifted the shift stalk to disengage fsd to get it to shut up with the alarm. Actually what this did was shift me into reverse. Light turns green, I step on the accelerator and I go backwards. This event would be impossible with a conventional shifter. the other major issue is in a school zone. I acknowledge that the software appears to have placeholders where it recognizes a school zone, brakes and proceeds. The issue however is, when on the zone, in fsd and having manually set to the zone speed, the crosswalk guard flags the lane to stop, fsd instead, proceeds to snap to the left and attempt to pass the car in front of me, breaching all zone protocol.

I was driving on highway 205 near Tracy CA. I was in the left lane approaching a left curve in the road. The right lane to me was occupied by a semi with "wide load" on the back. It was in its lane and just ahead of me. As we both approached the curve in the road, my car experienced a "phantom brake" episode thinking it was going to hit the truck. Again both our vehicles were in their respective land and the truck was not crossing over the line.

I'd like to register a complaint that features and functionality were removed from my vehicle at the request of the NHTSA inappropriately and for without justification. Several features including the ability to play sounds out of external speakers while moving were removed without any real study or analysis provided to justify the action taken. You did not provide any evidence for this change. No proof that it was a safety hazard at all. This is bullshit and I want my feature back. If you think this is an appropriate use of your authority you're a disgrace and a waste of government time and resources.

The emergency automatic brake, cruise control and auto pilot feature gets disabled frequently. All 3 features gets disabled at same time. Contacted tesla service center in decatur-GA. They are saying they cannot find the problem and hence cannot solve it. They say the engineers are looking into it, and my car needs a firmware update. No estimated time to fix these issues is given. The service center advised that the car is safe to drive! Please help. Thanks.

In moderate city traffic, the emergency braking system sounded and engaged prematurely and harshly. I was not using any automatic driving features and was driving “manually.” A vehicle in front of me stopped, and I intended to slow then stop in a reasonable fashion. I have 25 years’ driving experience, and am well-experienced to do this safely. The emergency braking system suddenly engaged at about 25 mph, grinding my car to a halt. The driver behind me was not expecting such a short stop, and rear-ended my vehicle. No one was injured in this crash. My seatbelt trigger deployed, which tripped the pyro fuse, rendering my car undriveable. I could not move my car off the roadway and caused traffic clogs. The repair bill was roughly $9000 for my vehicle. The weather was clear, the street was dry and the sun was near high noon.

My car when passing under signs or on two lane undivided roads will hit the brakes very aggressively. It’s difficult to reproduce and catches me and other drivers by surprise. The car didn’t do this during my first year of ownership, but now it happens several times a week. This will happen when using cruise control and autopilot. To me it’s rendered both features unusable.

Car engages self breaking while on autopilot without any particular reason. Repeated brhavior happened and almost caused rear end collision.

I was traveling on the 91 freeway headed west in corona, ca. I was in the fastrak lane approaching an overpass. I was using the cruise control option and going about 73 mph when out of nowhere my vehicle acted as if someone slammed on the brakes. We were moving with the flow of traffic and luckily I had my foot resting over the gas pedal so I immediately pushed down to override the system. The car behind us had to change lanes to avoid hitting us.

Vehicle was at a stop with brake engaged and then it proceeded to go full speed into a vehicle two meters away without acceleration pedal engaged. Emergency brake did not activate during or slightly before the collision. The brakes had to be engaged manually, but vehicle was already past a certain velocity on its own accord to be able to stop properly without damaging property or harming pedestrians.

Need to ship vehicle to Hawaii however the remedy for the active recall is currently unavailable.

The Tesla lane assist and adaptive cruise control failed while I was driving on the highway (I-295 in DC). I have not paid for the full self driving, so I was using the autopilot every Model 3 uses by default. The car skidded into the barrier on the side of the highway and tore up the back left tire and scraped the car. Autopilot was engaged but the car didn’t slow into the turn. I started to slow it down manually by down clicking the knob on the steering wheel, but it lost control even though autopilot was on the entire time. I’ve driven on autopilot on that highway hundreds of times. Autopilot always slows down on its own going into a turn. I was paying attention and am a very attentive driver. But autopilot normally would never have a problem with a turn like that, so I didn’t want to hit the brakes or do anything to disengage autopilot at the last second. I thought that would make things worse. I took over manually once it hit the barrier, obviously. At that point, I kept it from veering back into the other lane so that it would not hit the car next to me. Normally, there is more traffic ahead of me when I drive in that lane at that point on 295, so autopilot slows down because there are cars directly ahead of me. In this case, there were no cars ahead, so the autopilot didn’t reduce speed until later than normal. But I have been using Tesla autopilot for almost 3 years. It normally works quite well. The issue here seems to be that the autopilot does not see far enough ahead. Even though a sharp turn was coming up, it did not slow down at all until it was very close to the turn in the highway. The reason I am reporting this now is that Tesla ignored me when I reported it. I brought it in for service, and it cost me $1500 for Tesla to repair the wheel after the crash. But Tesla didn’t investigate the failure by the autopilot, or pay for it. And I saw on the news that you are investigating autopilot failures, so I thought you should know about this one too

Last March we drove to Tampa Florida and on 3 occasions using cruse control the car came almost to a stop felt like I hit brakes very hard. each time we were in the middle of a highway with no cars around us. I called Tesla they said do report a bug. The weird thing is each time it was at dusk. I just read an article and thought to report it. I am not sure if Tesla reported it. It has not happened in the last 6 months but very scary when it happens.
