2022 Tesla Model 3 complaints

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

As I was driving the car today, I had a car ahead of me at a full stop, so in order to slow down the car I lifted my foot off the acceleration pedal. However, instead of slowing down it sped up. My car has regenerative breaking (and it was turn on) which usually applies break when the pressure is lifted from acceleration pedal. However in this instant my car started speeding up. I then applied pressure on breaks, however it didn’t work. Fortunately the car ahead of me moved ahead and an accident was averted. My break and accelerator started working as expected moments later. But this can cause accident anytime. I have booked service request with Tesla. Also note that the car was not on Autopilot.

The car, on 6 occasions, rapidly decelerated while using the Autopilot feature when no obstruction was present. This was on the freeway, on a sunny afternoon, and seemed to occur at random without regard to overpass shadows, hills, etc. This nearly caused a collision from a car following me on one of the occasions.

The contact owns a 2022 Tesla Model 3. The contact stated that while driving at 40 MPH, the vehicle inadvertently turned to the right and then to the left. As a result, the contact stated that he momentarily lost control of the vehicle and collided with a barrier wall before careening to the right again into traffic. The air bags did not deploy. No warning lights were displayed on the instrument panel. A police report was not filed. No injuries were reported. The vehicle was towed to an independent mechanic, and the failure has yet to be diagnosed. The vehicle has not been repaired. The manufacturer was notified, and a case was opened. The failure mileage was 27,000.

Vehicle was being moved across the parking lot in Summon mode. It crossed a parking aisle and went into the next aisle, striking a parked vehicle with a passenger inside.

I was driving on Interstate 25 north towards Santa Fe NM at about 75mph with the cruise control engaged. The car abruptly slowed down to about 60 mph for no apparent reason. The slow down was so quick that passengers were pushed forward in their seats. This has happened before when cruise control was engaged. I had hoped that this was resolved by Tesla. There was not any vehicles in front of me for the car to believe a slowdown was necessary. I reported this to Tesla for repair and they replied that a repair was not necessary. They gave me instructions to override the action by pressing the acceleration pedal. I don't believe that is the solution to the problem and fear that if another car was following to close behind me that an accident could have happened. This car was purchased with cruise control but I cannot utilize it for fear of this braking problem

This was a case of phantom braking. While on the freeway with the cruise control set to 80 mph the car suddenly and unexpectedly slammed on the brakes. I had to step on the throttle to make the car stop braking. We were nearly rear ended by the car behind us. You can definitely come and inspect the car. I have not taken the vehicle to Tesla for inspection. No accident resulted from this incident, however it was definitely a very close call. There wasn’t a vehicle in sight ahead of us for at least a half mile. The car had no reason to slow down the way it did. I use Autopilot on my Tesla all the time. This is the first time I’ve experienced this behavior.

"Phantom braking:" Vehicle has braked Multiple times on the freeway while using adaptive cruise control, when no objects were In the vehicle's path. Typically occurs when driving on curved section of freeway at speeds above 50 mph.

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

While in cruise control the vehicle initiates braking rapidly for no reason. This happens at high speeds 55, 65 and 70 mph on clear roads. No vehicles in front of or coming from the other direction. There may be vehicles behind at times. It doesn’t happen all the time but happens enough to be a concern.

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

During a 30 mile trip on a two lane highway I activated the cruise control. A number of times the car made significant slow downs. They seamed to be associated with oncoming trafic. I then shut off the cruise control. Later on when I could see there where no oncoming cars I again set the cruise control for 65 MPH. After only about 15 seconds the car made a rapid deceleation. The deceleration was rapid enough to cause an ice chest sitting on the passangers side of the front floorboard to roll over. I shut of the cruise control and did not use it again for the remainder of the trip

In about a dozen incidences with my 12,000 mile model 3 the breaks come on unexpectedly. In one case i was on I-70 being followed by an 18 wheel truck / trailer when the phantom breaking occurred. Except for the attention of the truck driver and him slamming on his breaks to avoid rear ending me, I wouldn’t be here. I’ve opened 2 service complaints with Tesla and their response is that it is a learned correction for the car - Well it isn’t working.

My 2022 Tesla Model 3 was hit on a highway from behind the car with 100 mph , the car spun multiple times and hit the guard rail. The Car Rear and front side was heavily damaged due to the impact but the Air bags were not deployed. The Car is declared total loss. The car is less than a year old and does not have any issues. Police report says that the Car Air bags are not deployed. There are no warning sign or any failures before the crash. I want to bring this incident ( Tesla AirBags for Model 3) to you attention as this is a Safety and risk to other drivers driving the same car.Also, i do have the Crash report if required.

While driving in cruise control, NOT AUTOPILOT, my car phantom braked. The road was clear, the weather was clear. I'm thankful there was not a car behind me. I was doing the speed limit at the time 70mph when the incident occurred. the date lised below is an approximate date. It has occurred several times. I drive 45 minutes to work Mon-Thurs and cruise control helps for the long drive

Trip to California and back from AZ. Had several instances of severe braking. If I did not press the accelerator immediately, the car would slow down under what seemed like nearly maximal braking. No reason was apparent for this behavior. Some braking instances were on long straight stretches of I-40 with no other cars visible. This issue was only occurring if I had the cruise control engaged. Under normal daily driving without cruise control this issue of emergency braking does not occur. Each time this happens, it is totally unexpected and is extremely disturbing. I have stopped using the cruise control function on the vehicle out of fear of it causing an accident.

CAR HAS PHANTOM STOPS ON CRUSE CONTROL THREE TIMES IN SIX MONTHS

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

The contact owns a 2022 Tesla Model 3. The contact stated while driving approximately 80 MPH with the cruise control set at 80 MPH, the vehicle independently slowed to almost a complete stop. The contact stated that she pulled the vehicle off the highway. The contact stated no warning light was illuminated. The contact returned the vehicle to the highway and engaged the cruise control and set the control to 80 MPH; however, the vehicle failed accelerate to the designated speed. The contact stated that the inadvertent phantom braking failure recurred. The contact turned off the cruise control and continued her trip. The contact had taken the vehicle to a local dealer, where it was diagnosed, and she was advised that the manufacturer was aware of the failure but a remedy was not yet available. The vehicle had not been repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 9,000.

When we're traveling on the highway at 55 mph plus and have cruise control engaged, the car will unexpectedly and suddenly brake for no reason. The problem is happening more often. This has even happened when there are vehicles behind us, but thank God they were not following closely. We may end up with whiplash, or worse, being rearended. We have complained to Tesla at least 3 times since February 2022 about this problem. The first time, they changed the front camera and said they thought that might help. It didn't. The next time, the service dept. said that there was no fix for the problem, but Tesla was working on it. Most recently in April 2023, the service tech., said there was no fix and he did not expect that there would be one anytime soon. This is unacceptable.

When driving on a vacation and on a highway from Tucson, AZ to Laughton, Nev we experienced what is being called PHANTOM breaking traveling approximately 75 mph several times. Extremely lucky to have not been rear ended. It also has happened with the FSD Beta late last year when I leased the software for a month. Can supply dates.

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

Hello, I recently drove 600 miles and experienced numerous random, frightening and dangerous occurrences of "phantom braking" while in cruise control mode. The car suddenly slammed on the brakes (I could hear the tires screech) while the highway was almost always completely empty, and always completely devoid of any potential danger. In three occurrences, the car was confused by something physical (albeit posing no danger at all): it was confused a "divide highway" sign post at the beginning of a divided highway median, the distant back a truck, a least a quarter of a mile ahead, and an incoming truck a least a quarter of a mile ahead in a long curve. In all other occurrences -the vast majority of occurrences- whatever triggered "phantom braking" was nowhere to be seen (the highway in front of me was completely empty of any traffic or obstructions), and never materialized. My safety and the safety of drivers behind me (and potentially in other lanes in case of a pile-up) was compromised during every occurrences. I stopped using cruise control when a car or truck is behind me. I contacted Tesla Service. They did an over the air check and said that there was nothing wrong with the system, that each occurrence provided data to improve the Beta system (it would have been nice to be told when I purchase the car that my family and I were Beta testers of an automotive safety product), and that Tesla is "working on a firmware update". Not very reassuring, and most importantly, no fix

I was driving my car north on I15. Suddenly the car applied full breaks when there was no objects on the road. I could no longer control the car. Even when my foot was on the accelerator the car automatically depressed the break pedal. Luckily there was no vehicle behind me. I was also fortunate that we were going on a straight section of road. If this happened mid turn I would have completely lost control. These cars are a danger to society. It is impossible to drive them safely when they take control away from the driver.

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

Driving on the freeway at night, cruise control was on and going 70 mph. There were no other cars around and the car started braking on me out of no where. My speed went from 70 mph down to almost 20 mph on the freeway. Luckily there was no one behind me otherwise it would have been a bad crash.

I have had several incidents of my car rapidly decelerating when in assisted driving mode and I am driving on the highway. I am driving at 65 and all of the sudden it decelerates, making it extremely dangerous. There are no apparent barriers or nearby objects causing this to happen. I am very concerned this will result in a significant accident. I have filed this claim previously without anything happening. Additionally, I had a problem with my rear warning signal not going off when I was in a parking garage, causing me to back into a car. I filed a claim with Tesla and never heard back from them.

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

I love my Tesla but I hate the computer. It is dangerous! More accurate to say I hate the UNFRIENDLY user interface. I am surprised NHTSA OKed this computer interface. It needs a GOOGLE quality voice activation feature. The current one is deaf to most words normally used to drive a car. E.G., to turn the lights on while driving on a road where “LIGHTS ON” is required. I must hit a button to see all controls. Then I must hit the “LIGHTS” button. Then I must hit the “LIGHTS ON”. All this while having trouble reading the small print on the screen. The reading is difficult. All this while taking my eyes off the road to even see the screen. This is just one of very many examples. The actual use of the computer is VERY OFTEN more user UNfriendly and UNSAFE than the “LIGHTS” button. Dangerous, DANGEROUS. I almost killed another driver when my car was new because I was WORKING the computer and I ran a red light. Fortunately my car stopped because I hit the breaks or because the car was, in fact, SMART??????? I am surprised NHTSA OKed this computer interface. The computer is smart but using the interface is dangerous.

The Tesla computer and especially the USER INTERFACE IS UNSAFE. More accurate to say I hate the UNFRIENDLY user interface. I am surprised NHTSA OKed this computer interface.

Fortunately my car stopped because I hit the breaks or because the car was, in fact, SMART??????? I am surprised NHTSA OKed this computer interface. The computer is smart but using the interface is dangerous. I want to bring this issue up to NHTSA, not to issue a recall, but to ADD on a user interface as good as GOOGLE? What is the chance that they will re-investigate a safety decision they have already made?

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

Nearly every time I use the "Traffic-Aware Cruise Control" on my Tesla, I experience a phantom braking event. Nearly all the time it is when the road is clear, in the daytime. I use this feature infrequently because I cannot rely on it at all and I'm concerned it will cause someone to hit my from behind.

Just completed a 3 day cross country trip from Palm Desert CA to Saint Paul MN. On a long highway trip like this, we rely on 'cruise control' to maintain consistent highway speeds. Tesla provides adaptive cruise control as a feature of Autopilot. On numerous occasions, the adaptive cruise control unexpectedly stopped, causing the vehicle to slow, or unexpectedly braked hard causing the vehicle to sharply reduce speed. Due to the frequency of Tesla autopilot phantom braking, I found that my foot needed to consistently hover over the accelerator pedal to counter the numerous instances of phantom braking. This was necessary to prevent a possibly inattentive driver behind the Tesla from driving into the rear of the Tesla or another vehicle driving behind the Tesla. This phantom braking occurred as many as 6 to 10 times per day over 3 days and approximately 2,000 miles. The adaptive cruise feature malfunctions under certain conditions and our vehicle is available for inspection upon request. Our safety and the safety of others was put at risk by unexpectedly slowing or braking hard while driving at posted highway speeds and putting our vehicle at risk of being rear ended, and perhaps the same for a vehicle behind our vehicle. The phantom braking issue has been well documented in press & social media and I find it difficult to believe that it has not been reproduced by an independent organization such as NHTSA. I believe that the manufacturer (Tesla) is aware of the phantom braking

Complete shutdown or blanking screen while driving causing GOD knows what is working and what not. definitely driver won't know his/her speed, car systems status like blinker, auto pilot,...etc until the system comes back to become available. 1st time this happened, Tesla sent me its service mobile service person who mentioned that he could not find anything wrong and if it happened again he will schedule the car for an in-house service center appointment for the main computer unit to be replaced. When the incident happened again Tesla scheduled the service appointment but after inspection the report came back that this is a recurring incident in many teslas and require a firmware update! Service report attached (Job number 4 and 5)

Vehicle will repeatably go incorrect speed limit while on Autopilot or Fsd(beta), internal mapping data has incorrect speed limits, sometimes 65 in a 30, other times 25 in an unmarked 55. Speed limit may change multiple times within a short distance making it hard to correct without slowing or speeding up This is on software 2022.45.12. ( fsd 11.3.3), has been a constant issue on previous versions, also affects regular auto pilot

On a two lane road with no traffic approaching and no traffic behind us on us95 in the Nv desert, the model 3 slammed on the brakes and slowed from 60mph to 30 or less. This is with the adaptive cruise control engaged, not auto steering. This happens several times. There were several times when large semi trucks were approaching in the opposing Lane and the model 3 slammed on the brakes also when adaptive cruise control was engaged. When we reported this to Tesla they said they need the exact date and time of each incident, or they could not help us. These breaking incidents happened during a 12 hour trip between Carson City and Rancho Cucamonga. This is an unbelievable safety hazard as if someone is following too closely and the car suddenly decide to apply the brakes. The person behind you is going to be caught off guard and crash into you. I cannot believe this is been going on for over a year as I have read several articles about the problem. There is no warning whatsoever when the car does this.

On 3/16/23 at 3:30 PM, my car came to a complete and sudden stop on the highway and would not move. The only warning was a slight lurch the car made a few second prior to shutting down. The car would not restart or go out of park. I sat on the highway waiting to be hit from behind. I was on a bridge with no shoulder. Eventually the IL police arrive to block the lane behind me and use their truck to push me off of the bridge to where I could pull onto the shoulder. The trooper noted that they have had other calls of Tesla stopping in the middle of the highway and locking up. Currently the vehicle is in the Tesla service department and they have provided no diagnosis yet.

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

The accelerator pedal snapped off without any warning while driving on the interstate attempting to pass a vehicle. As I pressed the accelerator pedal, all resistance in the pedal disappeared and vehicles regenerative braking immediately engaged despite my efforts to maintain a safe speed on the interstate. Due to the regenerative braking and the lack of an accelerator pedal, I quickly found myself in the very dangerous situation in which my car was attempting to come to a stop from a high rate of speed in the middle of the interstate. I was luckily able to make a hard right turn to cross a lane of traffic in order to reach the safety of the emergency lane just before the car came to a complete stop. While doing so, I nearly clipped the front of another vehicle. The vehicle was towed to the dealership where it was serviced and a new accelerator pedal was installed. However, the service department had notified me that they had never had an incident like this before and even had difficulty knowing exactly how to fix it. The service to replace the accelerator pedal took nearly two weeks, leaving me without a reliable vehicle for my daily work commute. Upon picking up my vehicle, the service department also could not confirm that the vehicle was test driven with the newly installed accelerator pedal which heightened my safety concerns even more. When I asked to speak with someone in regards to my safety concerns going forward, no manager was available despite phone calls, message

With the autopilot engaged, on the freeway, and at freeway speeds, the car will automatically brake without reason and without any traffic in front of the car. In a stretch of 100 miles, the car did this 8 times. The car even "phantom brakes" on regular cruise control. This is not only alarming but dangerous! Had the road been wet, or slick, we could have easily crashed! THIS MALFUNCTION NEEDS IMMEDIATE ATTENTION! Thank you, Steve & Liza Starr

While using autopilot the car randomly decelerated from 75mph to almost 30mph in the highway (I75) super quickly. If a car has been behind it might have caused a crash.

I ran over an object in the road too small to see. The tire burst and went flat. The burst also created a hole in the wheel itself. The alloy/material from which the wheel is constructed was not strong enough to keep a hole from being created when the tire burst

I used Autopilot on my Model 3 for the first and only time a few weeks ago, and had a terrifying experience with "phantom braking" that could have killed my entire family while going ~75mph on the I-5 near Bakersfield, CA. The I-5 here is split with 2 lanes in each direction, and is straight with no bends. I was driving in the right northbound lane, with Autopilot engaged (adaptive speed control only, no automatic lane-steering). My right foot was off both pedals and two hands were on the wheel. There were no other cars in sight except for a single car driving northbound behind me in the left lane. This car began to pass me on the left, and when its front bumper was aligned with the mid-point of my car (I could just barely see the front bumper through the corner of my eye), my Tesla suddenly automatically slammed on the brakes with absolutely no warning! I immediately clenched the wheel as hard as I could, and had to quickly respond to prevent the wheel from automatically veering to the left. While fighting the wheel to try to keep the vehicle straight, and my family hanging on for their lives, we screeched to a grinding halt at a 45 degree angle facing the left lane. We were extremely lucky to not hit the passing car and fortunately there were no vehicles behind us. I disengaged Autopilot and quickly got out of there so we weren't vulnerable. I speculate that the camera on the left panel between the driver and rear door saw the passing car, and wrongly invoked automatic evas

Since taking ownership of vehicle in summer 2022, have experienced multiple incidents of vehicle emergency braking for no apparent reason while using cruise control. In a few instances when I have attempted to use cruise control again after initial phantom braking incident, there is a 2nd incident of emergency like braking for no apparent reason in the same trip. Have never attempted to reuse cruise control within same trip after experiencing issue twice in that one trip. When phantom braking occurs: - It is while using cruise control (with or without steering assist). - There is no audible or visual warning (not even from auto emergency braking system) before or during vehicle braking. - Is a very strong braking force akin to an emergency maneuver. - There is no clear reason for why vehicle braked - no obstacles in road or slowing traffic. - Level of traffic (light or moderate) does not seem to be a factor, but I don't use system in moderate to heavy traffic. - Weather does not appear to be a factor - it can occur in perfect driving conditions (sunny, clear day). In most recent incident, was traveling at 78mph on highway with no traffic in front or behind vehicle for approx. a half mile in either direction. Without warning or reason, vehicle began to brake hard, slowing vehicle down to 62mph before I could disengage system (approx 1-2seconds). Unclear how low vehicle would brake to if cruise control wasn't disengaged. Cruise control feature feels extremely risky to the point

The contact owns a 2022 Tesla Model 3. The contact stated while her husband was driving 80 MPH with the cruise control activated, the vehicle jerked forward and decelerated to 52 MPH. The contact stated there was no warning light illuminated. The driver deactivated the cruise control and continued driving to his destination. The contact stated she also experienced the failure on February 27, 2023. The vehicle was not diagnosed or repaired. A dealer was not contacted. The manufacturer had not been informed of the failure. The failure mileage was approximately 1,000.

The window is opening alone

The contact owns a 2022 Tesla Model 3. The contact stated while the vehicle was parked, she noticed that the driver’s side window would activate while the vehicle was turned off. The contact stated that window would roll down independently. There was no warning prior to the failure. The vehicle was taken to the dealer and the contact was informed about NHTSA Campaign Number: 22V702000 (Visibility). The vehicle was not diagnosed or repaired due to parts not being available. The manufacturer was not notified of the failure. The failure mileage was approximately 3,812. Parts distribution disconnect.

TESLA MODEL 3 DUAL MOTOR-WITH AUTOPILOT ADDITION TO PURCHASE VEHICLE HAS REPEATEDLY DEMONSTRATED ABERRANT BEHAVIOR WHEN IN “AUTOPILOT” MODE. DURING FREEWAY DRIVING THE VEHICLE HAS “MISSENSED” LANE SPACING AND UNEXPECTEDLY ATTEMPTED TO DIVERGE OR SWERVE, EXIT OR TURN OUT OF OR OFF OF THE LANE WE HAVE BEEN DRIVING IN. THIS HAS OCCURRED WHEN AN OFFRAMP OR CHANGE IN THE LANE DEFINITION OCCURS AND IS NOT “REGULAR”. SUCH AS A LANE THAT FOR SOME REASON IS NOT MARKED WITH A NORMALLY DEFINED WIDTH, OR A BREAK IN THE LINES THAT DEFINE THE LANE. DURING FREEWAY DRIVING THIS VEHICLE HAS SUDDENLY AND FOR NO APPARENT REASON, DRASTICALLY REDUCED ITS SET SPEED DURING AUTOPILOT DRIVING. WE WERE DRIVING IN RELATIVELY STRAIGHT, CLEAR AND UNOBSTRUCTED LANES ON OPEN HIGHWAY WITH NO TRAFFIC OBSTACLES. ON MULTIPLE OCCASIONS OUR VEHICLE HAS ACCELERATED BACKWARDS WHEN SET IN DRIVE. THIS HAS OCCURRED WHEN WE ARE BACKING UP TO MAKE A 3 POINT EXIT UP OUR DRIVEWAY. AFTER BACKING UP, STOPPING WITH OUR FOOT ON THE BREAK, AND SETTING THE CAR IN DRIVE, IT REPEATEDLY MOVED BACKWARDS. WE HAD TO RESET THE POWER, ON MULTIPLE OCCASIONS, PHYSICALLY GET OUT AND PUSH CAR FORWARD IN NEUTRAL TO AVOID BACKING INTO OUR GARAGE. THIS CONCERN WAS REPORTED WITH VIDEO EXAMPLES TO TESLA REPAIR CENTER. WE TOOK THE CAR THERE, THEY EXAMINED IT AND DID NOT FIND OUT WHY IT WAS DOING THIS. SINCE IT WAS EXAMINED, THE CAR HAS REPEATED THIS BEHAVIOR. I HAVE NOT YET REPORTED THE REPEATED INCIDENT, AS I HAVE 0 CONFIDENCE THAT THEY WILL S

While in the cruise control mode my car will periodically come to an abrupt slowdown. Often when I’m on the freeway and I am very concerned that one day I will be rear ended by the cars totally unexpected slow down. It has happened at least 30 times in my Tesla model 3

The "traffic aware" cruise control automatically slows the car when entering a portion of highway with a reduced speed limit. Sounds good in theory and Tesla says this is intentional and cannot be modified in settings. However, suddenly slowing down from 65 mph to 45 mph when all traffic PERSISTS at 65 mph could lead to rear end collisions or loss of control.
