This morning, I was waiting in the left turn lane on [XXX] turning east onto [XXX] in Moorpark, CA. Waiting at the light, I tapped to turn on autopilot and expected it to turn left… it tried to make a right turn from the left turn lane. This is not the first time autopilot has tried to make an unsafe and illegal turn from the wrong lane. I once had it attempt a U turn from the right lane on [XXX] .

2020 Tesla Model 3 driver assistance complaints
Page 3 of 8: complaints 41 to 70 of 194, newest first, as owners wrote them.
I am contacting you regarding campaign #23V‑838 and the recent Tesla software update, which I believe has compromised the safety features of my Tesla Model 3. For over two years, I’ve trusted my Tesla’s capabilities, notably its autopilot feature. However, the latest update has introduced a wheel detection system that’s overly sensitive and disruptive. Previously, my driving experience was smooth, responsible and safe, with hands on the wheel and autopilot assist for when I needed to make blind lane changes, allowing me to look over my shoulder briefly at the blind spot while the wheel kept straight without rear ending anyone. Now, with this mandated update, I’m forced to make frequent, forceful adjustments to the steering wheel. I can’t look away from the front of the car even briefly to check my surroundings. This constant intervention and forbidding drivers from looking around to check for safety is distracting and dangerous, leading to abrupt autopilot disengagements and brief rapid ways in which the car behaves as the car disengages and throws you into manual when you weren’t expecting it. This isn’t just about inconvenience; it’s a safety hazard. I’m now more focused on maintaining autopilot than on the road and surrounding conditions. This undermines the very purpose of the feature. As someone who’s always vigilant about my surroundings, especially at intersections, I find this update counterproductive. It forces me to turn off the feature, leaving me without the assistance that I’ve come to rely on for safer driving. I urge you to review this matter with utmost priority. The balance between driver engagement and the autopilot system’s safety has been significantly disturbed by this update. Necessary adjustments are needed to prevent potential accidents and ensure that this technology continues to enhance driving safety and efficiency. Thank you for addressing this critical issue.
I am writing to bring to your attention a concerning issue regarding the recent update related to recall alerts in my vehicle, which has inadvertently led to an increase in distraction while driving. I received a software update for my vehicle, which included new features aimed at enhancing autopilot alerts. However, instead of improving safety, these updates have unintentionally resulted in an increased level of distraction while driving. Issues Identified: Frequency of Alerts: The frequency of recall alerts has become excessive, leading to a constant stream of notifications while driving. This has proven to be highly distracting and has compromised my ability to focus on the road. Alert Presentation: The visual and auditory presentation of the alerts is intrusive and often occurs excessively during driving. The alerts are not sufficiently streamlined to ensure minimal disruption, causing a significant distraction. Impact on Driving Behavior: The continuous alerts have forced me to divert attention away from the road, leading to an increased risk of accidents and compromising overall road safety. Recommendations: As per most other vehicle brands that benefit from self-driving technologies, like Cadillac and Ford, they are not affected by this recall, and do not make the driver continually look at the display for information regarding to the alert. Intelligent Alert Timing: Incorporate a smart algorithm that considers the driving context before issuing an alert. This can prevent alerts during critical driving moments, reducing distraction. Comprehensive Testing: Conduct thorough testing of software updates before release to identify and address any unintended consequences, such as increased distraction. Before this update, it was a lot less distracting to drive this vehicle, due to the limited notifications. Since this update, I've found myself removing my eyes from the road because of the increased notifications. A reversal of this recall is in need.
While operating TACC with lane keeping assist, I experienced multiple iterations of phantom braking when the road and weather was clear ahead. This phantom braking could potentially cause other drivers to collide with the vehicle that unexpectedly braked in the middle of the highway. This problem has been a common issue with multiple people taking their cars to the service center to get checked out with no problem identified. There are no warning lights or indicators that the Tesla is going to phantom brake on the highway. Recommend having Tesla provide information regarding this phantom braking.
At 11:47 AM Pacific time on December 23, 2023 my Tesla model three auto pilot system failed after a recent update mandated by the federal safety agency. Ever since the update, the vehicle, cruise control and auto pilot systems no longer function properly, and while I was in, cruise control and auto pilot traffic stopped ahead and the auto pilot system disengaged while I was waiting while it was slowing down, which has never happened in four years of ownership and over 60,000 miles of driving. The new recall software update has made the vehicle unsafe and it should be retracted and corrected. What once was a safe feature is now unsafe. Please investigate this with Tesla to prevent possible injury or death resulting from this programming failure.
Your latest mandates has arguably made the car less safe by removing what allowed the system to operate safely. Please roll back this “recall” it’s not a recall in the slightest it’s a shot at someone or multiple people that dislike Tesla.
An incident occurred in April of 2023 while running FSD Beta 11.3.6 firmware. I have been unable to retest this location on more recent software, so this concern may have been mitigated with a subsequent update. As seen in the video, the yellow lane marking on the left transitioned from the roadway up onto the movable center median. Once on the bridge, the left repeater camera and the center display visualization both illustrate the lane centering was definitely biased towards the left side of the lane, a possible indication the vision-based lane centering was miscued by the yellow line now appearing on the barrier instead of the road surface. This left bias brought the vehicle uncomfortably close to the barrier, which resulted in a manual takeover. It is difficult to judge based on the low resolution of the repeater camera view, but my estimation is that the tires were approximately 12 inches away from the protruding bottom lip of the barrier. [XXX] This same left lane marking concern also occurs at the entrance to the Oakland, California Caldecott tunnel eastbound bore. The Google maps link provided shows the yellow line which defines the left lane edge disappears at the tunnel entrance, at which time the vision-based lane centering seemed to be cuing off of the curb as the lane edge, rather than there being a marking that would delineate a lane edge further away from the curb. An FSD beta user (name and date unavailable) reported contacting the curb at this location at approximately the same date as the GGB recording. [XXX] The GGB matter was brought to the attention of the Bay Area Toll Authority with the suggestion they contact Tesla. I have been unable to verify that the Toll Authority followed up on that suggestion. The release notes for Beta 11.4.4 suggest the issue might have been addressed, to wit, "Improved offset consistency when controlling for static obstacles."

I am writing to urgently express my concerns about the latest software update for the Tesla Model 3’s autopilot system, which, in my view, significantly compromises safety. As a Model 3 owner for over two years, I have generally found the vehicle and its features to be reliable and safe. However, the recent update has introduced an overly stringent hands-on-wheel detection mechanism that is not only inconvenient but also potentially hazardous. The new update requires frequent and often forceful interaction with the steering wheel to assure the system of driver presence. This change is drastically different from my previous experience, where I received only one hands-on-wheel violation in two years. The current sensitivity of the system disrupts the smooth operation of the autopilot, leading to frequent and abrupt disengagements. I have found myself struggling to maintain the system’s activation, inadvertently causing the vehicle to exit autopilot mode multiple times. This issue goes beyond mere inconvenience; it actively detracts from driving safety. The need for constant and sometimes aggressive adjustments to satisfy the system’s requirements is distracting and can lead to erratic vehicle behavior. The irony is stark: a system designed to enhance driving safety and ease is now a source of potential danger and stress. The unpredictability and over-sensitivity of the updated system could lead to dangerous situations, especially on highways or in heavy traffic, where sudden disengagement of the autopilot can be particularly risky. As a driver, I now find myself more focused on keeping the autopilot engaged than on the actual driving conditions and surroundings, which is surely contrary to the feature’s intended purpose. You need to investigate this issue as a matter of urgency. Adjustments are necessary to prevent potential accidents and ensure that the tech helps, not hinders.
During a month-long road trip in the US, I experienced frequent "phantom braking" incidents while using adaptive cruise control. In some cases, Autosteer was also active. By "phantom braking" I refer to sudden hard braking by the car itself in clear daylight conditions on interstate highways with no vehicles visible ahead of me for at least 1/2 mile. By "frequent" I mean that this behavior occurred multiple times per hour over multiple days. I decided to cease using cruise control for the remainder of the trip after the following episode occurred. With cruise control active on a four lane interstate, I was changing lanes to the right to allow a pickup truck to pass me on the left. I had just passed a semitrailer, who was in the right lane. I could see him in my rear-view mirror as I began the lane change. The road was empty and visible for at least a mile ahead on a sunny morning. We were all traveling about 75 mph in a 70 mph zone. While straddling the lanes, the car suddenly slammed on its brakes, requiring both vehicles behind me to take evasive action. I over-rode the car’s action by pressing the accelerator pedal swiftly and firmly. No accident occurred. I stopped using cruise control entirely for several months, and I have only rarely used it since then, and only when the road behind me is empty. In those few recent trials, I have not experienced any phantom braking. Finally, I speculate that the braking may have been triggered by "mirages" of what look like puddles on the road. We humans are familiar with this phenomenon, but the camera AI may have interpreted those as obstacles.
Phantom breaking occurred twice while driving east on highway sr 152. Our car was traveling straight with no cars in front of us. I was using cruise control set at the speed limit when the car suddenly slammed on the brakes, the car slowed from 65 mph to 20 mph in a few seconds. This happened twice in a matter of 10 minutes. I no longer use cruise control. Apparently there is no fix. I have two relatives that have experienced same problem with their Teslas. I will suggest that they report to the federal safety agency.
While driving on the highway from philadelphia to allentown using I-476 north i was driving using cruise control and the car suddenly applied brakes ( phantom braking) there was no one either in front or sides or behind me. No accident happened
At lease several times in the past 3 months, when using AUTOPILOT and when passing semi-trucks on my right my Model 3 has automatically given a very loud, what I believe to be either a Forward Collision Warning or a Lane Departure Warning, then braked and seemingly veered to the left! This is scary beyond belief and has only happened when AUTOPILOT is engaged and large semi-trucks are to my right. I thought you should know about this issue. Thank you,
Driving on the freeway with the adaptive cruise control set to 78 mph. Traveling in the #1 lane, medium traffic, no vehicles in front of us for a while (in our lane or the #2 lane next to us). Roadway was dry, sun was overhead at that time of the day. Weather said it was 72 outside, so not excessively hot. While nearly cresting the top of a slight incline, the car hard-braked, taking the speed from 78mph to 58mph for no obvious reason. (Thank heavens the car behind us was following at a safe distance and was able to brake, too.) There was no debris on the roadway or any other reason why the car would need to brake. Suffice to say that we deactivated the adaptive cruise control for the remainder of the journey.
I've had the car since December 2019. The car will "phantom brake" when the autopilot adaptive cruise control is on. This happens intermittently, ~1 time per month on my normal commute. I will be going along, cruise set to 75 and out of nowhere it'll slam on the brakes and lose 10 MPH in a second before I can take over. This occurs with absolutely no traffic or reason, it'll be an empty highway and it does it. I drive with my foot over the accelerator so I can floor it to override the car. This is the exact opposite reaction I would think that someone should have to do with a safety feature. Tesla tells me the system is working fine, but random brake checks on the highway should never be normal. I don't understand how this system was approved to operated by the government.
I was driving on the Garden State Parkway in New Jersey in the right hand lane. I was using basic auto pilot and needed to pass a pick up truck in front of me. I disabled auto pilot and went into the left lane. I re-engaged auto pilot and the vehicle took a hard right and hit the truck. I heard the audible chime once it made contact with the truck indicating that auto pilot disengaged. My car went back into the left lane and I took control. We moved to the shoulder and waited for state police to arrive. Luckily no one was injured. A police report was filed.
On September 9, 2023, we were driving from Winter Park, CO to Omaha, NE. Three or four hours into our trip, we experienced what is described on the internet as "phantom breaking" four or five times in an hour. We were in a remote area on I-80 with no cars ahead of us or behind us and no debris in the road. We have occasionally experienced this hard automatic breaking for no obvious reason before in our almost four years of driving this Tesla, but we never thought much of it. This time since it happened so many times in such a short amount of time, we researched online if there was anything we could do. With that information we turned off the "Automatic Emergency Breaking", which seemed to do the trick. When we contacted the Tesla Service Center in Council Bluffs, IA for an appointment to see if they could fix the problem, they asked for more information. They said the following: "We performed a remote diagnosis on the Autopilot System in the vehicle and its affiliated hardware and all checks came back in good standing with no faults." They then suggested I read the Owners manual for factors that may cause the vehicle to brake when not required or expected. I read it and told them none of those conditions were present. They said that was all they could do and suggested if it happens again I should file a "bug report" (which was a new concept to me!). The phantom breaking happened, but Tesla either doesn't seem to believe me or does not have the ability to properly diagnose or fix the problem. I will try to remember to turn off the Automatic Emergency Breaking, but that raises other safety concerns . . . .
On 9/3/23 we were traveling from Moab UT to Green River UT and the cruise control was engaged at highway speeds. We were not using the "Autopilot" functionality. Without warning, the car suddenly decelerated under what felt like hard braking. There was no warning immediately before the hard braking started and the car had no warning indicators of any kind either before or after the incidents. The hard deceleration happened at least four times. One of those times a raven flew up from the road, but the other times there was nothing in the road. At least three of the incidents occurred on highway 6 traveling north. The last time it occurred was on I-70 westbound after we stopped the cars and cleaned all the cameras and ensured there was no debris on the front bumper which could cause issues with the forward-looking radar. We lost confidence in the cruise control feature and did not enable it for the rest of the trip. This is a safety issue because the car does not just reduce speed, it feels like it is braking hard or perhaps full regeneration of the battery. Either way, on these 2-lane highways, there are often situations when other drivers are driving too close to the rear bumper and a sudden, inexplicable hard braking is very likely to cause collision. A collision at these speeds could push the car into oncoming traffic, leading to fatalities. We asked Tesla service to look into the issue, and said there is likely footage of at least one of the events (because I honked the horn to start recording). The Tesla service person gave several reasons why it deceleration may occur, but Tesla is neither reviewing the footage, nor taking action to remedy the issue. They said "Our remote diagnostics has confirmed the vehicle hardware is operating as expected and there are no repairs the service team can make in regards to this." With service unable to make a fix to the car, this problem remains unresolved and we have lost confidence in cruise control.
I have had multiple incidents of sudden speed reduction on major hi ways. (us 287 and I 25). Usually these incidents occur when I am traveling north (increasing elevation and later in the day), but that is not always the case. The events appear to be totally random, but result in a speed reduction of 70mph to 40mph rapidly enough that loose items (including pets) fly. on occasion I have had to be very quick to accelerate to avoid being run over by a tailgater. I scheduled a service appointment, but was discouraged from doing so by Tesla Service people who said “the car is still learning”. The fault has not improved. If anything it happens more frequently. At this point, I would say we travel “on edge”.
The contact owns a 2020 Tesla Model 3. The contact stated that on three occasions while driving at various speeds, the vehicle experienced phantom braking. The contact continued driving. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 13,000.
Sudden hard "phantom" braking while in adaptive cruise control. This put myself and other drivers in danger of a collision. The problems been reported to Tesla, but as of yet not fixed or inspected.The problem seems to be completely random with no advanced warning of any kind.
The car repeatedly rapidly decelerates when passing semi-trucks on the highway. This creates a problem for vehicles driving behind my vehicle as it creates sudden braking for them and it creates a bit of panic for the driver of my vehicle due to the suddenness of the braking. This problem occurs almost every time the vehicle is driving over 60mph on a freeway and is midway in passing a semi-truck trailer truck. The dealer has replaced the camera but the problem still occurs. Collision lights occur at the time of the error but no other warnings occur.
While driving on the freeway, my 2020 Model 3 “phantom braked” multiple times while using the cruise control. No autopilot for lane keeping assistance. There were no cars in front of me or any hazards. The pavement was pretty new. I was using this feature earlier in the trip with no issues then it started all the sudden with multiple incidents in a short amount of time.
My car cameras and audio will randomly stop working. Come to find out I took a recording with a timestamp of 1151 pm where I am on the highway and driving. Have witnesses of me driving and the issue. My model 3 logs, as stated by service technician, say my vehicle is "Parked and not being operated". This means I am driving with potentially dangerous and absolutely unreliable software in my car. It shows the car isn't being operated as I am going 60~ on the highway in traffic. My car cameras will go completely black and the audio warnings will go out including the backup sounds which are a required feature. Have contacted Tesla since 2020 and no action except a blanket statement of "a future update"
Phantom Braking occurred almost 40 times on our recent trip from Northern NV to California and return. We left on July 16 and returned on July 21. Our route was from Minden NV to Las Vegas on Highway 95 and then onto Temecula CA on Highway 15 and 215. The return trip was on Highway 15 to CA 138 to Highway 14 to Highway 395. All travel was during daylight hours. Sometimes phantom braking was so severe, the deceleration cause us to be thrown forward towards the dashboard. We wore seat belts to prevent hitting the dashboard. This also happened on a similar trip in 2022 and was reported to Tesla and were told that nothing could be done. The current software version is 2023.20.9
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.
While driving on the freeway I5 in central California in the middle of the day there were no cars in front of me and the vehicle went into sudden PHANTOM BRAKING mode. I was driving at 75 MPH and it suddenly went into hard braking. Extremely dangerous. The vehicle behind me had to swerve around us. We could have been killed. I was using the cruise control but NOT the Enhanced Autopilot. This needs to be fixed. We escaped severe injury or death by sheer luck
Had cruise control on and “phantom braking” occurred about 10 times on a 22hr trip from California to Oklahoma. Very scary. Car went from 80 to about 40mph in seconds. How is this even possible for Tesla to have these vehicles on the road? I’ve only had the car for 2 weeks.
I was driving from indio,ca to Orinda,ca on interstate 10-210-5 north and the vehicle had at least 6 phantom braking events when the car was in cruise control and one event the auto pilot was on. There was clearly nothing front of me. This is so dangerous and there will be a bad accident if it isn’t fixed. Please have Tesla fix this.
Recurrent phantom braking while using autopilot. Sudden deceleration that does not seem to correlate to any specific traffic or weather condition.
When driving on a longer trip, I have repeated sudden deceleration and sometimes harsh braking when using cruise control. This has also happened in normal daytime hours with no traffic around me on rural interstates. On my last trip, I had to keep my foot on the accelerator to keep the car at a constant speed. It is unnerving to me and very scary for passengers. It has made it impossible to use cruise when I have passengers. Tesla has said there is no hardware issue and have declined to service the car.
