Adaptive Cruise Control Problems of Tesla Model Y - part 2

In early Nov 2025 my Tesla Model Y began intermittently showing warnings about the forward collision warning system and multiple sensors being offline. Tesla service replaced a faulty connector on Nov 3. On Nov 15, 2025, about two weeks later, the car had a sudden drivetrain failure while I was parking on a steep hill. I heard a loud bang from the front of the car and the vehicle immediately lost drive power and had to be towed. Tesla diagnosed a failed front motor inverter that blew the high-voltage pyrofuse and damaged the 12v battery; they replaced those parts. The vehicle is available for inspection and the repaired components and records are with Tesla. After that repair the car needed another visit for alignment and has continued to show worrying behavior: “vcfront offline/unable to contact vcfront” in the service menu, repeated “autopilot computer overheating” messages, intermittent loss or reduction of regenerative braking (braking feel changes unpredictably), a rear right seatbelt malfunction warning (later inspected and cleared by Tesla), and what appears to be significantly increased battery drain compared to before the inverter failure. This has now resulted in four service visits within about a month, all at Tesla service centers (no police, insurance, or independent shops involved). Tesla has confirmed the inverter/pyrofuse/12v failure and says the overheating was due to an air pocket in the cooling system, but the vcfront messages, inconsistent regen braking, and increased drain have not been fully resolved or clearly explained. I am concerned that a sudden loss of power, loss of regen, or failure of vcfront/autopilot systems could recur at speed or in traffic, creating a serious safety risk. Please note that I'm only able to view partially-complete paperwork from the latest service appointment in the Tesla app. I have requested this documentation from Tesla and will be able to provide all the service reports and communication as a follow-up.

While driving in rain at night, the vehicle’s automated driving system attempted to make a turn at an intersection near active train tracks. Instead of remaining on the roadway, the system steered the vehicle directly onto the train tracks, where the vehicle became stuck between the tracks and the paved road surface. All four tires were damaged, and the vehicle could not return to the travel lane under its own control. If a train had been approaching, this situation could have resulted in a severe or fatal collision. I had to manually reverse the vehicle a significant distance to return to the roadway. The malfunction appeared to result from the automated driving system misidentifying the roadway under rain and low-visibility conditions. This suggests a recurring risk for any vehicle using the system at this location in similar conditions. The safety issue has not yet been inspected or confirmed by the manufacturer. No warning lights or alerts were displayed prior to the incident. The affected components and system are available for inspection upon request. I also have dash-cam video of the incident documenting the event.

I am writing to report critical safety issues I’ve experienced while using Tesla’s full self-driving (fsd) software version 14. 1. 3. The recent update has introduced several dangerous behaviors that were not present in previous versions. One issue occurs frequently on neighborhood roads: the vehicle performs sudden emergency braking for no valid reason. For example, during one drive, it abruptly stopped because a few leaves blew across the road. There were no pedestrians, vehicles, or real obstacles present. These false-positive braking events are alarming and could easily cause a rear-end collision. An even more concerning issue arises during highway driving. The car now repeatedly swerves partially into adjacent lanes—without signaling—and then abruptly returns to its original lane. This happens constantly, even in light traffic, and it did not occur in previous versions of the software. This erratic behavior is incredibly dangerous and could easily cause sideswipe accidents or create confusion for surrounding drivers. It is clear that version 14. 1. 3 is a regression from earlier versions. The system’s decisions are more erratic, less confident, and frequently unsafe. I no longer trust the fsd to operate reliably in environments where it previously performed well. I urge your agency to investigate this software update as it presents a real and growing hazard on public roads.

Fsd was unable to avoid object in road, may be due to how the adaptive headlights work as I was unable to see the object as well fsd/adaptive headlights may may it hard or impossible to see objects on road at night no in the process of a insurance claim no.

Recently Tesla released it's latest version of fsd, v14. 1. 4. One of the key features is the revamping of the driving modes: sloth, chill, standard, and mad max. Tesla also removed the ability to manually increase or decrease the speed of the car. This is a problem. Let me illustrate it with a real-life example. Yesterday I was driving of a 40 mph road and the car correctly set the speed. I was using the standard mode so the car allowed an overage of around 10% so the actual speed was 45 mph. In our area this is typical for most drivers. As we entered a village, the posted speed limit was changed to 30 mph. The panel was perfectly visible and readable. The car did not register it and continued at 45 mph. I changed to mode to "sloth" and the car decreased its speed to 40 mph but I was still 10 mph above the legal speed limit. I came across a second 30 mph panel and again the car "ignored" it. Because I did not have the ability to manually reduce the speed of the car, I had to disengage fsd and drive the car by myself. Tesla claims fsd must be supervised. Fine. But removing the ability to manually change the speed of the car should be a requirement not a design preference.

Tesla fsd v14. 1. 3 feels unsafe for the typical “average” driver because it no longer allows users to set a maximum speed limit offset when using the standard driving profile. In fsd v13, drivers could specify a max speed offset—such as 10% or 15% above the posted limit—when fsd was enabled. However, this option is no longer available in fsd v14. As a result, fsd v14 in the standard profile often speeds on highways and makes aggressive lane changes to pass slower vehicles. This behavior feels unsafe and stressful for most everyday drivers. Tesla should restore the ability for each driver to set their own comfortable max speed limit and reduce the aggressiveness of lane changes.

New update to asds software allows the vehicle to do 15-25+ over the speed limit and no ability to control. This is unsafe and Tesla took away the ability to control speed. Either engaged or not, this is completely unacceptable and they seem set on this being the only way to go.

Tesla fsd issues: 1. Phantom braking sudden to a full stop for no known reason in the middle of the road, throwing my dogs into the floor and the car stopped completely on the highway. If an infant had been in the car ina car seat, their neck could have been broken 2. Sudden jerkiness when making turns 3. In one case the car suddenly changed lanes and was a close encounter. 4. Fsd system is now completely non-functioning. 5. These issues started about about 1 month ago and worsened in the past 1 week after the latest software update. Tesla premium connectivity navigation issue 1. Instead of taking me on main roads to my destination, it has been taking me down rural, isolated dirt roads. In one case I was directed to a dirt, logging road, isolated and dangerous terrain. I had to turn around in a secluded area and the navigation system kept directing me to dirt roads, although main roads were close by once I opened my iphone for directions. 2. In lynchburg, va the navigation directed me towards an exceptionally steep downgrade to the river and would have been a catastrophe 3. These issues started this weekend 10/24 - 10/26/25 door locks 1. Door locks respond occasionally and there have been times I left the car assuming it would lock but it had not. There is no rhyme or reason to this. 2. This issue started 10/25/25 I am following up with Tesla next but thought you should be made aware. I did the recent Tesla software update and things just got worst.

My 2024 Tesla Model Y hit a parked vehicle on the right side of the street during fsd self driving. The car suddently slanted to the right and hit the parked vehicle. During fsd drive, it did not give any warning before the accident. My dauther was injured on her face. Clearly the new version fsd v14. 1 software is very defective. I am located in san jose, CA.

Upon purchase of the vehicle, unlike previous models and versions of the software - the vehicle’s speed limit control was incapable of being set - instead, using fsd, you had to select from percentage based offsets - which were frequently ignored and would still go much higher or much lower than the percentage value set. The owner of the vehicle was unable to say limit to only 10 over the speed limit; instead it was percent based and not reliable. In addition, more than a third of the time - the speed limits in the infotainment system did not match the posted speed limits. Sometimes, in the middle of a highway - it would randomly go from 55 to 25, posing a significant threat hazard when using the fsd or cruise control system (which is something Tesla charges extra for access to) causing the vehicle to immediately decrease speed when other vehicles behind are getting up to speed and not expecting a vehicle to randomly slow down excessively. Additionally, when you manually override the speed limit control, or the system does, the user interface hides this limit so the driver is unaware of what limit of speed it is set to. These issues were already bad enough, but just yesterday my vehicle was pushed a software update that dramatically reduced the performance of fsd, and now I am unable to manually control the speed limit at all in fsd. This was a regression from purchase, when a scroll wheel at least allowed me to manually set the speed limit or correct it when it was wrong. Now, that feature has been removed and instead there’s a duplication of fsd profiles (left/right on the right scroll wheel does the same as scrolling up/down). And continuing this trend, the driver is incapable of seeing what the speed limit is set to because it’s hidden from the user interface. In addition, the driving behavior for fsd has significantly regressed from before the update. Cruise control’s most basic functionality should be to set a speed limit. Now this feature has been removed.

On the day of the incident, I drove my vehicle into the charging station and activated the Tesla fsd autonomous driving and automatic parking functions. During the automatic parking attempt by the vehicle, the system exhibited the following severe loss of control behaviors: 1. The vehicle automatically collided with the vehicle in front without any human operation. 2. It paused for about 1 second after the collision. 3. Then, the vehicle suddenly accelerated in reverse at high speed, again without any driver operation. 4. It directly hit another Tesla that was charging behind my vehicle. The entire process is fully executed automatically by the vehicle system. I cannot intervene or stop the system through the steering wheel or brakes. Ii. Severe security risks when the accident happened, my friend was sitting in the passenger seat. If the vehicle had moved a few more inches, it could have caused serious injury or even a life-threatening situation. This system failure is a combination of sudden unintended acceleration (sua) and the loss of control in autonomous driving decision-making, posing a significant systemic risk to public traffic safety. I immediately contacted Tesla and sent a complaint letter to the north carolina consumer center. They accepted my complaint and sent an email to Tesla, but it has been over twenty days and I have not received a response from Tesla.

Tesla removed the speed limit offset feature in fsd version 14. 1. 4 and now only uses speed profiles called sloth, chill, standard, hurry, and mad max, and this has made my car extremely unsafe to drive. The problem is that these profiles make the car go either way too slow or way too fast and I cannot adjust it to match actual traffic conditions anymore. To make matters worse, the speed limit detection is broken and frequently shows the wrong speed limit for the road I am on. When I use sloth, the car never goes over the detected speed limit no matter what, so if the system thinks I am in a 35 mph zone when I am actually on a 55 mph highway, my car crawls along at 35 while traffic is flying past at 60-70 mph. I have people tailgating me, honking, flashing their lights, swerving around me dangerously, and I have almost been rear-ended multiple times because my car is going so much slower than everyone else. Without the ability to set a maximum speed offset, I am stuck going whatever speed the broken detection system thinks is right. If I switch to standard, hurry or mad max to try to keep up with traffic, sometimes the car goes way too fast for the actual conditions or blows through school zones and residential areas at unsafe speeds. I cannot fine-tune the speed anymore to drive safely with the flow of traffic. I am forced to either be a rolling roadblock and risk getting hit from behind, or use an aggressive profile that might go dangerously fast. This happens every single time I use fsd now and the combination of broken speed limit detection plus no manual offset control has created a seriously unsafe situation. I feel endangered every time I drive and I am genuinely worried about causing or being in an accident.

Reporting fsd incident on 10/08/25 approx around 8. 15 pm I was going on I-90 towards western mass / u mass amherst using fsd on 10/08/25 on I-90 road work was ongoing and it was 2 lanes. All the vehicles started going in the right lane as left lane had cones . Left lanes cones were tapering on its way ahead. My Tesla fsd chose the left lane which I would not choose as I saw at the distance cones were tapering to form a single lane . Tesla fsd drove in left lane and as it noticed cones tapering into single lane fsd acutely cut into the right lane in front of the of the truck at a very very narrow margin . Once the right lane , fsd asked me to take control of the car. From there till u mass amherst I could not use fsd . This was scary experience. I wanted to report using voice command but I got busy . Please you must have recording of the event. No body was hurt no vehicle damage just wanted to make aware about fsd.

My vehicle’s auto-high beam system does not properly recognize other traffic. It specifically fails to substantially dim the high beams when approaching oncoming vehicles or when behind other traffic on roadways. I have reported this to the manufacturer and attempted to have the dealership fix this on multiple occasions. The dealerships insist that the vehicle dims the required number of pixels in the headlights to not blind other drivers. However, this does not appear to be effective as other drivers that I have followed behind reported that they were being blinded by my highbeams while I was behind them. There is a notable difference between the highbeams and the low beams which the car fails to substantially adjust for when using this required feature to utilize the self driving/auto pilot feature.

While on a two lane road, my car decided to go around the car in front of me into on-coming traffic while in full self-driving mode. I had to jerk the car to the right to prevent a head-on collision!!!! I missed the on-coming vehicle by seconds!!! this was terrifying!.

I would like to formally report several incidents I have experienced with my newly purchased Tesla Model Y. I acquired the vehicle on [xxx], collected it from washington d. C. , and drove it back to houston between September 20 and 21. Prior to my return journey, I conducted a test drive. During this drive, at dusk, I engaged full self-driving (fsd) mode. The vehicle stopped appropriately at a traffic light; however, once the light turned green, it moved forward but veered into the yellow safety buffer zone located between the lanes of opposing traffic. I intervened by manually steering the car back into the correct lane. A similar occurrence happened in washington d. C. While attempting a left turn under a highway overpass—the vehicle again crossed into the yellow lines. These incidents suggest that the fsd system did not reliably detect the yellow lane markers. On the weekend of [xxx], during my drive to houston, I primarily used fsd. While navigating a road construction zone, the system failed to recognize large safety cones (yellow columns) and nearly collided with them. Fortunately, I was attentive and promptly took control, braked, and changed lanes to avoid an accident. This demonstrated the fsd’s inability to identify these safety markers. On Tuesday, [xxx], I drove the vehicle to work and returned home using fsd. As I exited the highway onto a ramp merging with frontage lanes, I observed that fsd did not reduce speed appropriately and nearly made contact with vehicles on the frontage road. This indicates that the system was unable to interpret the ramp as a short section intended for deceleration and safe merging. On [xxx], while returning home in the evening after work, I used fsd due to light traffic. The vehicle navigated turns and stops satisfactorily and paused roadside before my house. When I resumed manual control to park, the vehicle suddenly became unresponsive, accelerated onto my front yard, struck the flower bed stones, information redacted pursuant to the freedom of information act (foia), 5.

Bought a brand new Model Y and I less than a week I received the below two error message warnings and the airbag light comes on. Cabin occupancy radar obstructed. Front passenger safety restraint system issue. Also to engage the fsd, I have to double tab 2-3 times in order for it to engage.

The full self driving (supervised) adas in this vehicle will react to shadows on the road and can put the car or other cars at risk. We have had multiple instances where, on a sunny day, the car will react to shadows cast on the road and take evasive action like braking or switching lanes abruptly. This can be hazardous due to the random nature of the of the occurrences and them happening at times when a driver may be lulled into a false sense that the car seems to be driving itself well. So far we have been lucky that no other vehicles were traveling too close behind or to the side of us. We have experienced this behavior multiple times and there are other people online who have reported this. The car gave no warning indicators either before, during, or after the occurrence. Note that our car uses a hardware 3 computer. I believe that this issue may have been fixed on newer Tesla cars that use hardware 4.

Tesla’s full self-driving (fsd) system has repeatedly demonstrated unsafe behavior in my 2021 Model Y (VIN [xxx] , ~60,184 miles). The issues involve adaptive cruise control, lane keeping assistance, and forward collision warning. Fsd frequently follows vehicles too closely, leaving insufficient distance. When I disengage, I am left with no safe option: braking hard risks being rear-ended and triggers a hard-braking event, while lifting off the accelerator leaves me dangerously close, still flagged as unsafe following. Fsd often waits until less than a mile before highway exits to attempt lane changes, causing last-second darting, missed exits, or unsafe maneuvers. It also performs excessive and unnecessary lane changes that add risk without improving efficiency. Merges are frequently unsafe, forcing me to brake hard to let others pass or accelerate aggressively to avoid being cut off. On several occasions, fsd has jerked or swerved into adjacent lanes without signaling, seemingly triggered by shadows or changes in the road surface. These phantom maneuvers are unpredictable and hazardous. On [xxx] at about [xxx], at a t-shaped intersection, fsd failed to yield to a vehicle traveling straight with the right of way while I was making a left turn. I had to slam on the brakes to disengage, narrowly avoiding a collision. This was the second such incident in the same intersection in one week. These repeated failures—unsafe following, late exit attempts, failed merges, phantom swerves, and failure to yield—create significant risks for me, my passengers, and surrounding drivers. The problem has been reported to Tesla multiple times via in-car voice reports and a written service request, and logs from my vehicle should confirm these events. No warning lamps or system alerts appeared before or during the failures. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

This happened after I installed the most recent software version. My wife was driving with fsd enabled when the car suddenly braked hard. A little while later, as it was supposed to make a left turn, it suddenly accelerated on its own, ignored a red light, and drove straight through the intersection. A warning light appeared on the screen, notifying her that fsd was inoperable, but it was already accelerating, so it was too late to intervene. Therefore, the car crashed with another car. My wife, mom, and my baby were in the car, and my wife got injury on her face. I have a recorded video, and Tesla should have the log for that moment.

When using the adaptive cruise control or “autopilot” feature on my Model Y, the vehicle will brake extremely hard without warning. This sudden, unnecessary braking is commonly referred to as phantom braking. The failure is available for inspection upon request. This malfunction poses a significant safety risk to myself and others, especially vehicles following behind, as it could lead to rear-end collisions. The issue is widespread, with many other drivers experiencing the same problem. The problem is easily reproducible on highways, particularly at certain intersections where no obstacle is present. The system will sometimes display a “curvature assist” prompt despite the road being straight, causing the vehicle to brake abruptly. I have not taken the vehicle to a dealer because the warranty has expired. The issue has not been confirmed by a dealer or independent service center, nor has it been inspected by the manufacturer, police, or insurance representatives. However, I reported it directly to Tesla and have received no response. No warning lamps or error messages appear before the failure, aside from the inaccurate “curvature assist” prompt. Cause: unknown.

The curvature assist function activates and applies the brakes automatically on straight and level sections of freeways with no observable obstacles or curves, requiring driver to resume acceleration to override the brakes.

The forward-facing camera system, automatic emergency braking (aeb), and autopilot/cruise control have repeatedly failed on a 2023 Tesla Model Y with approximately 22,000 miles. The aeb system becomes unavailable and the autopilot disengages without warning, including at highway speeds of 70 mph and city speeds of 30 mph. The active safety systems are functional less than 10% of the time. The sudden, unexpected loss of active safety systems at speed presents a serious risk of accident and injury. The problem has been reproduced and confirmed by an authorized Tesla service center on three separate occasions. Repairs attempted include replacement of the triple forward-facing camera assembly (twice) and replacement of the car computer (hw3) with a firmware update. Despite these repairs, the defect recurred within days of each service visit. A fourth service appointment is now scheduled for the same issue. Warning alerts appeared on the vehicle display prior to each failure, specifically "camera blocked" and "automatic emergency braking unavailable. " these alerts were first detected in August 2025 and have recurred through January 2026. All three repair attempts were covered under the manufacturer's basic vehicle limited warranty, confirming acknowledgment of a manufacturing defect. The vehicle and components have been inspected by the manufacturer's authorized service technicians. The vehicle is available for inspection upon request.

Traveling today using the cruise control function in Tesla Model Y, the car took over the control of the car and applied braking for no clear reason. Was going 70 miles an hour, had been using the cruise control for about 30 minutes when incident occurred. There were semi trucks in the slow lane, I was in the fast lane. There were no vehicles in front of my car. The car suddenly lunged forward as the brakes were automatically applied. Simultaneously, the steering wheel began to jerk back and forth causing the car to veer back and forth. Vehicles around me began braking as well to avoid rear ending my car and to avert hitting my car as it veered back and forth. I had to fight the steering wheel in an attempt to pull it off the active roadway and then the car suddenly gave all control back to me at which time I was able to disable the cruise control and take full control.

While driving a Tesla Model Y on a freeway in arkansas, the vehicle was operating in autopilot mode (Tesla's driver-assistance system). During a highway merge, the vehicle followed a state trooper's car too closely and failed to slow down appropriately. The trooper had to apply his brakes to avoid a collision. After stopping the vehicle, the trooper issued a written warning, explicitly attributing the issue to equipment failure and advising immediate correction. This issue appears to involve a failure of the adaptive cruise control and forward collision detection system while autopilot was engaged. No collision occurred, but the situation posed a clear safety risk to both the trooper and my vehicle. This was not the first issue with the vehicle's automation. In a previous incident (November 2024), the vehicle exceeded the posted speed limit while on autopilot, resulting in a traffic citation. Tesla has been notified, and a service request is open. Diagnostic review is pending. There were no warning lights or alerts from the vehicle before the incident. The vehicle remains available for further inspection if required.

When using Tesla autopilot (adaptive cruise control) Tesla curvature assist will engage on straight roads during nice weather and great forward visibility. When Tesla curvature assist engages, the car brakes and slows dramatically. I have had drivers behind me think I was brake checking them or messing with them. This feature is dangerous and there is not an option to disable.

Accident involving my Tesla while the full self-driving (fsd) feature was engaged. Vehicle information: [2022, model - y, ] incident summary: while driving with fsd engaged, the vehicle hydroplaned and the steering wheel started spinning uncontrollably and despite attempts, couldn't regain control of the car, and it spun while crossing lanes. A truck hit the front of the car and ended up on shoulder.

Three different occasions, while utilizing adaptive cruise the car applied all breaks, causing me to lunge forward with the car coming to a complete stop. I did not see anything that would had caused the car to apply the breaks and the camera's did not record any obstacle. This was brought to the Tesla dealerships attention and I was told there is nothing that can be done about it. If I had not been wearing my seat belt, the potential emergency braking could had resulted in me sustaining a blunt force impact to my chest with the steering wheel, not to mention a possible motor vehicle accident with the vehicle behind me. I did look through the manual and there is no way of me turning feature off or lowering to a warning versus a suddent stop.

Update to odi 11678614. This problem applies to non-fsd (full self driving) Tesla Model Y cars. Tesla's manual describes autopilot as traffic aware cruise control - it's the first step on non-fsd cars. The second step on non-fsd cars, autosteer, is active lane keeping. In older ys, the first stalk pull engages autopilot, second pull engages autosteer. 2026 juniper doesn't have a stalk - a single scroll wheel press engages both. I read the 300 page juniper 2026 Model Y manual before driving it for the first time. On page 108, it lists 7 things that will cause autopilot to disengage. I presumed that comprehensive list was complete. Unable to attach. Having *autopilot* disengage when turning the wheel in *autosteer* is not listed. During my 59k miles on my 2021 model y, I used autosteer for at least 20k miles. Turning the wheel in autosteer did * disengage autopilot. In my first emergency situation in the 2026 juniper Model Y, turning the wheel * disengage autopilot, and the regen properly kicked in for the disengagement. This action came very close to causing a serious accident. My objections are 1) the action of *autopilot* (disengage / remain engaged) when the wheel is turned in *autosteer* is not documented, and 2) it's different between the old and new ys using the same current software. I understand there were problems with autopilot remaining engaged, and perhaps the change was a good idea; that's an entirely different discussion. Make the action consistent and document it and I'm happy. Summary: in heavy traffic, while on autopilot / autosteer (cruise + active lane keeping), the car beside me suddenly tried to pull into my lane. I made an emergency lane change by turning the wheel, but the cruise also disengaged, (contrary to operation in the prior model) and went to maxiumum regen braking, causing the car behind me in the new lane to nearly rear-end me. Punching the accelerator during the surprising braking avoided the collision.

I've driven my old 2021 Tesla Model Y for 4 years / 59k miles. Four days ago, I got a new 2026 Tesla Model Y. The new y has made a change to the interaction of the cruise control and automatic lane keeping. In the old one, first cruise was enabled, then lane keeping. If you disengaged lane keeping by overriding the steering wheel, cruise control was maintained. In the new y, a single selection enables both cruise and lane keeping. The safety issue is that overriding lane keeping by turning the steering wheel disengages both features at once - the old method kept cruise control enabled. I was driving in heavy traffic today on a 6 lane interstate with cruise and lane keeping enabled. The car next to me abruptly swerved into my lane, causing me to make an emergency lane change to avoid a collision. When I overrode the lane keeping to avoid the other car by turning the steering wheel, my cruise control also disengaged (unlike the old system), which caused maximum regenerative braking to kick in, abruptly slowing me in the new lane. I had to punch the accelerator to avoid being rear-ended in the new lane. This change in lane-keeping / cruise control applies to all new 2025/2026 Model Ys - the "juniper" model update. This change, according to reddit and facebook forums, seems to be universally hated and many other drivers have raised the same safety concerns. I agree with them, but didn't make a report until now because I had not yet experienced an issue where this almost contributed to a high-speed crash. Thank you.

In fsd mode, my Tesla Model Y always heads to the "do not enter" road and I have to take over manually to prevent entering the "do not enter" road. This has happened almost all the time I am there. This is a very unsafe. Tesla needs to correct this issue at their highest priority.

All cameras went blank on vehicle 4 year and 7 months old. All driver assistance systems became suddenly disabled. Tesla service diagnosis established that computer needs to be replaced for a cost of $2,000.

I have had multiple incidents of "curvature assist active" message appearing on screen while on cruise control. It suddenly reduces the speed of the car. This happens on a straight road with no curves or slope. It also happens at random. On the same stretch of road at the same time of the day, this issue pops up sometimes and doesn't on other times. Every time this comes up, the car reduces speed suddenly. For example, I go from 45 mph to 23 mph in a few moments. If there is a lot of traffic behind me and the car behind me was not expecting such a sudden decrease in speed as there is no obstruction in front of me, this could lead to a safety issue. I took the car in for repair. The technicians could not find out what the issue was. They said they recalibrated the sensors and test drove and did not see this occur. As this is occurring randomly it might not have shown up when they test drove. But, it happened to me when I took the car back and it keeps happening randomly at least twice a day. There is no specific location and/or time of the day. Tesla doesn't provide an option to disable this "curvature assist" feature for something so basic as cruise control. Along with this I have had 2 incidents where my car applied brakes suddenly when there was no obstruction in front of me. In both incidents, I had to immediately take over and speed up to avoid any issue with traffic behind me. If there is any safety incident due to these issues, Tesla will have to be held liable.

While driving along a few roads using traffic aware cruise control (tacc) or autopilot (ap), the car will suddenly brake for no reason at all. Speeds reduced from 75 to 50 in 2 seconds. Had there been a car close behind me, we may have collided. I am able to reproduce this on several other roads as well. I have not yet reported this to the manufacturer, but a review of internet forums shows this to be a relatively common occurrence among owners. They refer to this as phantom braking.

It is impossible to disable automatic emergency, breaking system permanently. The vehicle brakes strongly and abruptly causing the cars behind to slam on their brakes and potentially cause accidents. Every time I disable it, it comes back on next time we get into the car. There has been several instances where the vehicle hit the brakes really hard, even if there was nothing in front of it. . I was told that this is happening because Tesla does not use sensors but realize on cameras for these features and it can be quite wrong. I don’t know how to drive this car safely because the car makes decisions for me. Since it happens all the time, I’m having to keep my foot on the gas, and when it slams on the brakes, I counter it by pressing the gas pedal. The incident date is just an estimate, but it happens all the time.
