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/
2020 Tesla Model 3 complaints
Owner reports filed with NHTSA about this vehicle, newest first and reproduced as filed. They are unverified accounts: one proves nothing, and a pattern across many is the thing worth reading. Back to the full 2020 record →
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.
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.
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.
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.
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
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 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 car has randomly braked multiple times, for no reason at all. Maybe shadows or mirages?
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 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.
The contact's husband owned a 2020 Tesla Model 3. According to a police report, while traveling at 70 MPH, the vehicle veered across three lanes of traffic and hit a light pole. The contact was wearing a seatbelt and the air bags deployed upon impact. The paramedics arrived at the scene; her husband was intubated and taken to the hospital. Her husband was pronounced brain dead due to injuries suffered in the accident and passed away two weeks later. According to the police report, witnesses stated that no effort was made by her husband to avoid or slow down prior to the collision. The contact disputes this claim and stated that her husband was not a reckless driver and would not have intentionally hit a light pole. The contact believed that the cause of the accident may have been related to a mechanical failure and would like an additional investigation conducted about the accident. The vehicle was towed to an independent tow yard and destroyed. The manufacturer had yet to be notified of the failure. The failure mileage was unknown.
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.
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 ah
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.
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.
Car was stopped at a red light. All of a sudden car speeds up & was out of control despite applying brakes
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.
The car suddenly brakes when the accommodative cruise control or full automatic driving is engaged. This happens at random times when driving on the highway. The braking is sudden and severe requiring driver intervention. Only happens with cruise control or full auto. Has happened several times since the car was purchased.
While traveling on highway with Full self driving engaged car would occasionally brake and had to quickly press on the gas pedal for fear a car would hit me from behind. This seemed to happen when I approach an overpass but not most overpasses and typically happens once or twice during highway trips of about 80 miles on NJ garden state parkway. I had not reported this to Tesla or had the car checked for this issue and report it now seeing that there were formal reports filed on this issue to NHTSA. I do not recall whether any warning lights or audible alerts occurred during these incidents. First occurred after I took possession of car a couple of years back.
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.
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.
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
"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 i
The contact owns a 2020 Tesla Model 3. The contact stated while driving approximately 20 MPH, there was a loud sound coming from the vehicle. There was a warning message to take control of the vehicle displayed. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The contact related the failure to NHTSA Campaign Number: 22V063000 (Electrical System, Forward Collision Avoidance). The approximate failure mileage was 9,800.
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 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
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
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.
The contact's granddaughter owns a 2020 Tesla Model 3. The contact stated while her granddaughter was reversing, the rearview camera failed to turn on, causing the rear end of the vehicle to crash into a cement post. The contact was unsure whether there was a warning light illuminated. There were no injuries sustained. A police report was filed. The vehicle was towed to a Tesla-certified autobody mechanic but was not diagnosed or repaired. The vehicle was then towed to the contact's residence. The contact later received notification of NHTSA Campaign Number: 21V00D000 (Electrical System, Visibility, Back Over Prevention) however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure but did not provide any assistance. The vehicle was not diagnosed or repaired. The failure mileage was approximately 400. VIN tool confirms parts not available.
Sporadically when driving at highway speeds, car will experience an error. Steering assist IMMEDIATELY decreases (wheel harder to turn), cruise control (if enabled) will disengage, and following Error codes appear on flatscreen : - Vehicle Hold Feature Unavailable - Tire Pressure Monitor System Fault - Automatic Emergency Braking Disabled - ABS (Anti-lock brakes) disabled - Regenerative Brakes Disabled - Steering assist reduced - Traction control disabled Unsure of which component is at fault. Tesla Service center (Norfolk VA) has pushed off appointment for more than 30 days but has acknowledged that there is an issue. SAFETY: Loss of ABS is a major safety risk to occupants. Loss of steering assist also puts driver and others at risk due to increased steering effort. Loss loss of regenerative braking also a safety risk due to the instantaneous change of vehicle braking behavior when regenerative braking switches off.
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.
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.
The contact owns a 2020 Tesla Model 3. The contact stated while driving 30 MPH, he heard an abnormal noise. The contact stated no warning light was illuminated. The contact continued to drive to his destination. The contact stated he parked the vehicle, he noticed that a large section of the front passenger’s side rim was missing. The contact filed a complaint on the Tesla application and made them aware of the failure. The contact purchased the front passenger side rim from the Tesla website. The contact took the vehicle to an independent mechanic and had the front passenger’s side rim replaced. The contact stated that the vehicle was still driving to the right. The vehicle was repaired. The contact attempted to reach the manufacturer but was unable to speak to a representative. The failure mileage was approximately 28,500.
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.
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 contact owns a 2020 Tesla Model 3. The contact stated while driving at various speeds and using Self Driving feature, the vehicle experienced phantom braking. There were no warning lights illuminated. The contact depressed the accelerator pedal and continued to drive the vehicle. Additionally, the contact stated while reversing, the vehicle inadvertently moved forward and slightly bumped into a guardrail. There was no further information provided. The contact depressed the brake pedal and was able to successfully reverse after several attempts. The contact also stated that the vehicle would fail to make normal beeping sounds and alerts while reversing. The manufacturer was notified of the failure and informed the contact that unless he provided the specific time and date of the failure, they could not assist. The vehicle was not diagnosed or repaired. The failure mileage was approximately 10,000.
While driving at highway speed, the vehicle's automatic emergency braking unexpectedly activated, without cause or warning, which caused a very rapid deceleration of the vehicle. Fortunately, the traffic on the highway was light and no other vehicles were around, but this "phantom braking" had the potential for a major collision. This is the first time this has happened on this vehicle. The vehicle has not been inspected by the manufacturer and there were no prior warnings.
The upper control arm on my vehicle creaks and it is a known issue amongst the Tesla model 3 owners. This creak can eventually wear to the point the ball joint will separate during driving. This is a safety issue that can cause an accident. Tesla denied the warranty repair due to some after market parts. This is not a valid reason to deny me warranty because this issue is prominent in all cars of this model and year regardless of aftermarket parts or not. Currently the issue is present at low speeds. Tesla applied a "patch" to keep water from getting into their poorly designed ball joint. Unfortunately by the time they got to this repair for my vehicle it was too late. And water had gotten in and caused the damage and now it is a safety concern.
The contact owns a 2020 Tesla Model 3. The contact stated that while the vehicle was in reverse, the rear camera would intermittently fail to operate as needed. The contact had previously received notification of NHTSA Campaign Number: 21V00D000 (Electrical System, Visibility, Back Over Prevention) but stated that the vehicle was not included in the recall. Neither the dealer nor the manufacturer had been notified of the failure. The approximate failure mileage was 20,000.
My Tesla Model 3 is equipped with standard auto pilot (no full-self driving) and traffic aware cruise control (TACC or otherwise known as adaptive cruise control). While engaged, I experience, on average, per 60-mile trip a minimum of 1 phantom braking event. Note this is not on residential, county or state roads, this is on divided highways. The vehicle will slam on the brakes for no reason and will at times activate the forward collision warning system. It's so bad I've disabled many of the safety systems for fear I will cause an accident. Traffic aware cruise control on a two lane road (this does not steer or lane center the vehicle), is unusable because it constantly brakes for oncoming traffic in other lanes, or aggressively brakes for vehicles turning in front of you, even with plenty of distance to clear. The system will even continue to brake, after the turning vehicle has fully cleared the road. This requires the driver to slam the accelerator to cancel the braking action. When I first purchased the vehicle in February of 2020, there were no issues with Phantom braking. This issue has become worse with over-the-air updates. I canceled my full-self driving subscription because the phantom braking was even worse with that software. Additionally, Tesla uses a driver safety score to determine insurance rates if you are using their branded insurance program. When these phantom braking events occur it sometimes registers as an emergency braking event which deducts from you
There is a complete failure of the Autopilot (cruise control) feature and sudden braking when using. There is an extreme risk to personal safety when using this feature. On several occasions, I have been using this feature on the highway while going the posted speed limit of 65 or 70 mph. Suddenly, the vehicle will decelerate aggressively and violently causing any vehicles behind me to slam on their brakes to avoid a collision. This feature of the vehicle is not recognizing road signs, or other inanimate objects, correctly and mistakes them for some hazard that requires braking. Very dangerous.

NHTSA publishes every complaint as the owner wrote it and investigates only a fraction. Spelling, capitalisation and judgement are the filer’s own. What carries weight is repetition: the same component failing the same way across many filings, and whether the manufacturer eventually opened a recall for it.
