1 Vehicle Speed Control problem

Failure Date: 09/01/2025

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.

2 Vehicle Speed Control problem

Failure Date: 08/13/2025

Driving on I 880 south on the fast lane. The car suddenly braked for no reason and began to shutdown. It warned me to pull over before complete shutdown. Luckily there was space on my left and I was able to rolling stop. Nothing on the screen was working. Turned on hazard light. Got out of car with my phone. Accessed Tesla app and ran battery check. After couple mins the error went away. Tried to slowly move with hazard light on. It appeared to have fixed itself. Slowly merged back into freeway when it was safe. Attached notification when I tried to schedule service request.

3 Vehicle Speed Control problem

Failure Date: 05/23/2025

Unknown I was driving with no advanced driver assistance systems (adas). My vehicle took control of the steering wheel, swerving uncontrollably, almost hitting approaching cars, and a wooden electricity post. It was diffucult to keep the steering wheel steady. I struggled to pull the vehicle to the side of the road until I made a complete stop. A witness checked on me and was concerned that I had almost crashed.

4 Vehicle Speed Control problem

Failure Date: 05/23/2025

I have had supervised full self driving in the vehicle for well over a year. I have used the Smart parking feature Monday-Thursday to park the vehicle at work and it has worked flawlessly. On [xxx] around [xxx], I went to [xxx] . After entering the gate to parking on [xxx], I drove slowly. I was able to select a parking spot and tapped on it on the screen for the selection and then started the automatic parking. There were no other cars around as we were all just starting to enter the gate and park. The car began to move in reverse. It then paused turned the wheel a bit, turned it back, tried to decide what it was going to do and started to move forward. The car then drove up the curb on to the walkway and almost drove into the building. I was able to hit the brake quickly to stop the process. There was no damage to the building or the car. I had never had an issue with the Smart parking until this time. I then backed the car off the sidewalk and parked it myself.

5 Vehicle Speed Control problem

Failure Date: 02/28/2025

Tesla remotely disabled my vehicle twice (February 28, 2025, and March 6, 2025) without prior notice, legal justification, or a court order. February 28, 2025 – Tesla disabled my vehicle for 3 days my Tesla Model Y was remotely locked without warning, leaving me stranded and unable to use my vehicle. Tesla refused to provide a reason or reinstate access for three days. March 6, 2025 – Tesla disabled my vehicle again & attempted repossession Tesla again remotely disabled my vehicle, then sent a tow truck for repossession without legal notice. I called the police, who confirmed Tesla had no legal repossession order. Tesla refused to restore access, forcing me into a coerced “voluntary surrender. ” how this posed a safety risk I was stranded in public locations without notice or transportation alternatives. Had the vehicle been in motion, this could have caused a road hazard. Tesla’s lack of due process denied me the chance to dispute the action before losing my vehicle. Confirmed by law enforcement & Tesla’s own records police intervened on March 6, 2025, and confirmed Tesla had no valid repossession order. Tesla has refused to provide written documentation or a legal explanation for these actions. Regulatory concerns Tesla’s unilateral ability to disable vehicles raises serious consumer safety issues: what prevents Tesla from disabling vehicles arbitrarily? what legal safeguards exist to protect owners from unjustified manufacturer lockouts? should federal law restrict Tesla from disabling vehicles without court approval? request for investigation Tesla’s remote disabling practice endangers consumers and should be urgently investigated by NHTSA to determine if federal safeguards are needed.

6 Vehicle Speed Control problem

Failure Date: 02/18/2025

This is my 4th safety report about the same issue: unexpected braking while on cruise control. Since my last report, Tesla offered another free month of auto pilot but I did not take it for fear of this braking issue. On Tuesday [xxx] I was returning to my home in las cruces nm from colorado. I was on [xxx] toward albuquerque, and there was very little traffic. I decided to see if I could get away with the cruise control. As I was pulling into bernalillo, there were some oncoming cars in a left-turn lane at a signal, and my car braked automatically. . . Enough to lurch me forward. I decided to stop at the "new" Tesla dealer in bernalillo (I got my car in santa fe) and ask about the automatic breaking and whether they'd fixed it. The 2 service employees looked at each other and one said "no". I then asked about whether I needed to re-boot my key card since my screen went blank while I was in CO, during a snow storm, parked. I luckily had my phone and on the Tesla app, under roadside service, it gave me the option to re-boot the screen! I did so. The serviceman said he didn't think the blank screen had anything to do with my key card, but I could re-boot it if I want to. (a prior complaint also reported the failed key card in less than a year and Tesla's unwillingness to replace it). Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

7 Vehicle Speed Control problem

Failure Date: 12/18/2024

While using cruise control (tacc) or fsd, the vehicle inadvertently brakes until vehicle stops, due to detecting light glare or other things as a collision threat. This happened many times. Reported to Tesla service, they said it is a bug and I should file a bug report. I have previously filed many bug reports about this but no software update fixed the problem. Incident happened many times, Tesla should have records of all, because when there is a disengagement, driver is asked to tell what happened by voice.

8 Vehicle Speed Control problem

Failure Date: 11/21/2024

Harsh braking while using cruise control. Known as "phantom braking". This is causing extremely dangerous situations. The vehicle slams on the brakes while at high speeds for no apparent reason. Perfect weather and road identification markers. Happens with oncoming vehicles in normal path of travel as well as when there is a break in painted lines on the roadway. This creates a serious potential for an accident injury or death. Happens consistently.

9 Vehicle Speed Control problem

Failure Date: 09/01/2024

2023 Tesla Model Y has frequent phantom braking issues when using cruise control. Let me clarify I am not using any sort of auto-pilot or self driving options. I am simply using cruise control. The incidents that cause many braking issues are unjustified to the point I have no idea what the Tesla may have recognized to make it slam on brakes. Very dangerous.

10 Vehicle Speed Control problem

Failure Date: 08/23/2024

I have reported this same issue twice before. When on cruise control, the car brakes unexpectedly. My 2nd and most recent report was on June 2, 2024: ". . . I had already disabled "apply brakes when regenerative braking is limited" under dynamics on the screen. (see photo) he showed on the screen, under autopilot, that I could disable automatic emergency braking, which I did. I was concerned that this warning pops "the vehicle will not automatically apply the brakes even when a collision is detected" (see photo) but he suggested I try it to see if it would solve the cruise-control braking. I was hopeful, and disabled it, knowing that it might take a while to know if that solved the problem. I drove the 30 miles home on the frontage road instead of the interstate, and when there were no other cars around, I set cruise control at 50 mph, the speed limit. I came to a series of small hills in the road, and was reminded of the first time the automatic braking happened, on a 60 mph road with longer amplitude hills of greater height. Amazingly, it happened again! pretty significant braking and slowed me to 25. This time I waited it out to see if it would resume the cruise control at 50. It did not. I have since restored the automatic emergency braking as that seems important for a crash situation. I have restored the "apply brakes when regenerative braking is limited" since that obviously was not the problem either. " I did not use cruise control again until August 23, when I happened to be returning home from silver city to las cruces and was on the same highway, 180, where the problem first occurred. It is a 2-lane road and often there is no traffic, so I felt safe trying cruise control again. I set it at 55, the speed limit, and after only a few miles the car braked again. I do not use cruise control anymore, and was dismayed to find that Tesla is again offering a free trial of autodrive! this is a huge safety issue!.

11 Vehicle Speed Control problem

Failure Date: 08/16/2024

Driving north on [xxx] just north of red ond oregon on a 2 lane section at sunrise with traffic aware cruise control set the Tesla braked aggressively when a semi approached in the oncoming lane. Neither vehicle crossed the center line but the crash alarm blared and the car braked almost causing a rear ending accident. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

12 Vehicle Speed Control problem

Failure Date: 08/03/2024

While driving straight on a 2 lane divided highway, the traffic assisted cruise control decided it needed to slow itself down significantly to 15 mph under the speed limit (posted speed limit was 65 mph). There were no vehicles in front, behind, or beside my vehicle. The breaking occurred when it came across a line break where cars from the opposite side of track could turn left onto a service highway but no one was in that divide nor in the turn lane. There was no warning or any obvious indication that the vehicle should harshly slow down for any safety reason, where in fact is there was a vehicle behind me, it could cause a crash. I made a request for Tesla to repair the vehicle, but in my attached photos, you can see that they admit to the issue being software related and insisting that it is an unrepairable problem until a software update can be issued.

13 Vehicle Speed Control problem

Failure Date: 07/08/2024

The contact owns a 2023 Tesla Model Y. The contact stated while driving 35 mph, the vehicle misread the route 10 road sign for the speed limit sign and the vehicle decelerated to 10 mph. There were no warning lights illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 9,000.

14 Vehicle Speed Control problem

Failure Date: 06/25/2024

We were about the park in the marked parking lane and the vehicle unintedly accellerated, the brakes did not work and we saw message "automatic emergency brake not available" and air bags not available. We tried to control the vehicle to avaoid crashing into the porch of the infront apartment and steared the speeding vehicle and the vehicle hit the pillar of the aparement and finally came to halt few meters away in the parking lot as the front right wheel broke. 1. The adas automatic emergency breaking seems failed 2. Forward collission warning seems not working 3. The safety of the driver and the passenger were at risk while the collission happened 4. I am not sure if the similar incidents happened or can be reproduced by the dealer/manufacturer. 5. Vehicle components inspected by the Tesla collission center but no software logs inspected and they said that they cannot get the device crash/event logs. 6. At the incident/while the incident was underway we saw few message that displayed "automatic emergency brake is not avaiilable" and "air bags are not available".

15 Vehicle Speed Control problem

Failure Date: 06/13/2024

The contact owned a 2023 Tesla Model Y. The contact stated that while driving at 30mph, the vehicle independently sped up and took over the contact was unable to control the vehicle. The vehicle struck 2 parked cars, and 2 street signs. No warning lights were illuminated. No injuries were sustained. A police report was filed. The vehicle was towed. The insurance company deemed the vehicle totaled. The manufacturer was made aware of the failure, and a case was opened. The failure mileage was approximately 12,000.

16 Vehicle Speed Control problem

Failure Date: 06/12/2024

We were trying to park the car in our garage when the car suddenly sped up. And hit our the fence . I released the pedal but it kept driving until I hit the brake. Air bag did not deploy. The car?s front was smashed. Our fence is also badly damaged. I have asked Tesla to investigate if it was because of the autopilot taking over but have not received a response from them yet after more than a week.

17 Vehicle Speed Control problem

Failure Date: 05/28/2024

Was traveling along the I-5 south about 5 miles north of the 99 interchange. Vehicle was in traffic awareness cruise control when it suddenly applied the brakes. Vehicle did not sound any warnings. Vehicle did not display any warnings. Vehicle made no attempt to warn driver of a braking event. Vehicle traffic awareness cruise control was set to 79 or 78 mph in a 70 mile per hour zone. I was able to push the accelerator pedal to regain speed but had already dropped to about 65 mph. Vehicle did not pass under a shaded section ( I. E. No bridge or trees or big rigs) there was change in color of the road top. My foot was resting just in front of the accelerator pedal. Fortunately for us, there was no vehicles directly behind us. This incident is the 3 of this kind in this vehicle. This has me spooked to use any of the convenance software. I already do not like using the autopilot feature because of it erratic behavior. It feels very unsafe and unpredictable. We are unable to predict when this car will act on its own and feel it will cause us harm one day with actions like this. We are glad that no one was following us closely because they might have hit us. We are also upset that the vehicle never stated why it braked suddenly.

18 Vehicle Speed Control problem

Failure Date: 04/24/2024

I am reaching out on behalf of my wife who met with accident on 3/24/2024. She was driving Tesla y model and this accident occurred due to system failure of vehicle , brakes and steering wheel get locked and she was not able to do anything and car hit the couple of trees on other side of parking lot . She was not using autopilot feature and it vehicle didn't stop after applying the brake instead of stopping , its get accelerated and steering was also locked.

19 Vehicle Speed Control problem

Failure Date: 04/15/2024

Car was being driven into a car wash. Driver went to put car into neutral and car lurched forward and crashed into car in front of it without gas pedal being engaged. Vehicle has not been inspected by manufacturer or others. No warning lamps or other messages. May have been related to recently installed full self driving software that was automatically installed but was not requested by vehicle owner. Vehicle owner did not intend to engage any sort of self driving or automatic acceleration systems.

20 Vehicle Speed Control problem

Failure Date: 04/08/2024

Car warned that drivability - acceleration and top speed reduced/performance may be restored on next drive but gave no opportunity for me to pull over safely. Felt like someone pulled the e-brake during regular driving speeds and prevented me from safely slowing down, steering or maneuvering the vehicle into a safe spot. This occurred during a rainy night with my wife and 3 daughters in the vehicle who were terrified and still afraid to drive in the vehicle. Tesla replaced the front drive inverter and about a month later the same issue happened again on a busy road around 1pm in the middle of traffic and this time the rear drive inverter had to be replaced. Myself nor my family have felt safe in the vehicle but feel stuck with it.

21 Vehicle Speed Control problem

Failure Date: 04/04/2024

During a 2,300 miles recent trip in texas, the vast majority of the speed limit signs were not seen by my 2023 Tesla Model Y autosteer/autopilot (not fsd). This created issues with the autopilot/autosteer as it was not usable in several instances and can create safety issues like distractions, etc. . . I had the latest software revision. The key point is that this is not happening at all in colorado where I live. Tesla support responded that I needed my cameras recalibrated which is a totally illogical response as it is not happening in CO.

22 Vehicle Speed Control problem

Failure Date: 04/01/2024

You have no doubt heard the news that Tesla has deployed full self driving to all its vehicles as a "free trial. " my Tesla received this update in the past few days. Last night I was driving on an expressway and engaged what has up until now been traffic-aware cruise control by pressing down one time on the right stalk. I expected regular cruise control but the car started steering for me. Tesla has changed the default behavior of the cruise control activation (one single downward press on the stalk) to instead activate autopilot. My attempt to regain control caused me to jerk the wheel side to side in a way that could have led to an accident had I been in heavier traffic. This was unexpected behavior from the vehicle and I find it unacceptable that Tesla has changed a default function in this manner. I had to hunt around on the screen to find the setting to change the behavior back to regular traffic aware cruise control from one downward press. Furthermore, on the same 20 mile trip I had three phantom braking incidents while the car was on traffic aware cruise control mode. This is more than typical and these events can be dangerous if they happen in traffic. Tesla should not be allowed to deploy changes, especially without notice, that modify basic functionality of a car in motion from what the driver has become accustomed to.

23 Vehicle Speed Control problem

Failure Date: 03/23/2024

This car does not have full self driving, and I do not use auto steer. I experience multiple phantom braking events every time I use the "traffic aware cruise control. " sometimes I can see that the cruise control set speed has been reduced from the speed I set, and I have to cancel and reset it to resume the original speed. Sometimes the cruise control set speed is unchanged, and pushing the accelerator will cause the car to resume the set speed. Yesterday I drove 320 miles and had about 6 of these events. I'm concerned about these events causing an accident from the sudden speed reduction, or getting into a road rage situation because the person behind me thinks I am brake-checking them. Internet research indicates that these complaints are very common during the past few years. If Tesla can't - or doesn't want to - solve the problem, they should at least allow us to choose basic cruise control to avoid this problem. Adaptive cruise control would be more reliable with radar, but Tesla is doing everything it can to make the cars cheaper, and radar was eliminated. Personally, I think trying to do everything with cameras is a fatally flawed approach - especially considering cars travel at night and in varied weather and lighting conditions.

24 Vehicle Speed Control problem

Failure Date: 03/10/2024

I want to report what I think is a very dangerous issue with my Tesla Model Y. We have experienced numerous times that the car brakes without warning. I have talked to Tesla about this "phantom braking", and they say it is "normal". The traffic-aware cruise control cannot be disabled to create a normal manual cruise control. I gave them a hypothetical situation where this could be life-threatening, but they dismissed it. Two weeks later, that very scenario happened, thankfully not ending in tragedy. I was driving at 65 mph on a wide, two lane paved highway (near dove creek, CO). A car going in the opposite direction was stopped on the shoulder on the other side of the highway. A large semi truck, also going in the opposite direction, pulled into my lane to pass the parked car on the side of the road. I saw what was happening, let off the accelerator, and steered over onto the paved shoulder (wide shoulder) to avoid the oncoming truck. My car's traffic-aware cruise control, using the car's cameras, interpreted the situation as an apparent collision danger and automatically braked hard. In this situation there was a large pickup doing what most pickup drivers do. . . . Tailgating close behind me to get me to drive faster. Neither the driver of the pickup, nor me, were expecting my car to brake hard, as we had all assessed the situation correctly as not being dangerous. I responded as quickly as I could by pushing on the accelerator to cancel the cruise control, but the pickup almost rear ended me. At that speed, it could easily have turned into a fatal accident. Tesla says I can't disable the cameras, so I just don't use the cruise control now. I was told you can disable the "traffic-aware" part of cruise control on older model Teslas, but not 2023 and newer. Often the phantom braking occurs with no apparent reason (although the car's cameras and computer would probably disagree). Do many people have to be killed to take a safety hazard seriously?.

25 Vehicle Speed Control problem

Failure Date: 03/01/2024

Vehicle: Tesla Model Y blue purchased in oct’ 23 Tesla setting: regenerative braking (single pedal driving) issue: brake pedal/acceleration pedal malfunction I was pulling my car out from the parking lot to pick up my mom, from the hospital entrance. I just turned right and had to take an immediate left to leave out of the parking lot. The Tesla was driving at approximately 5 miles an hour at that point. I lifted my foot from the gas pedal for the car to stop with its regenerative braking. However, instead of coming to a stop, the Tesla started rapidly accelerating, with my foot not even on the pedal. When I slammed the brakes, the car was unresponsive and continued accelerating. I started honking madly to warn people that I had no control over the car I was driving. The vehicle continued accelerating over 100-150 meters in 4-5 seconds and banged a parked car (Lexus SUV) at the end of the parking lot. It continued accelerating while pushing Lexus over the curb, destroying road sign poles and landscaping shrubs; crossing the street, and the middle curb. At the end of the street was a tree and a ditch. Lexus couldn’t move any further and Tesla stopped. All airbags deployed. One of the emergency response detection systems called 911 immediately. The first thing the police asked me was if I pressed the emergency brake. I said the car doesn’t have one. I can’t even turn off the vehicle while it is moving. The parking button takes care of it. I used to love my Tesla but I can’t trust it anymore. What I want from them at this time investigate all the incidents thoroughly instead of blaming these as a user error. A) think about adding the redundancy system. Something mechanical where the driver reacts within a couple of seconds. Software bugs are hard and sometimes it is impossible to find the root cause. Logs may not contain everything that you need to debug the problem. Consider it as a p0 issue. B) compensate for the damage and property loss.

26 Vehicle Speed Control problem

Failure Date: 02/20/2024

On almost a daily basis, with the cruise control set to maintain speed (vs the option of advanced speed control that will adjust to signs), the car will inexplicitly and quite randomly decelerate aggressively at highway speeds. On four separate occasions just today(although it happens at least once or twice a day), with the cruise set to 70 mph, the car will randomly decelerate aggressively or even change the max speed of the cruise to 55 mph. On all occasions, the posted speed limit is 65 or even 75 mph. This is dangerous, particularly in dfw traffic during rush hours, with traffic flow moving at similar and often higher speeds in close proximity. Having my car aggressively decelerate without warning to 55 mph has caused me to be tailgated and honked at. This has been happening since I've received my car. At first, I tried to use the advanced features of the cruise, but whilst driving on the dallas tollways, where the toll road has a speed limit of 75 mph and the regular highway paralleling at 65, the car is unable to differentiate and would often interpret the wrong speed limit and aggressively brake. Going from the flow of traffic (close to 80 mph) to 65. This is why I switched the cruise to absolute speed rather than any sort of posted adaptive. It's seems to have gotten progressively worse. So much so that I only use the cruise where traffic is light because of this issue's unexpected and random nature. Besides being dangerous, it's also very scary as it's completely unexpected and aggressive. I did make a service support call, but the Tesla technician said it's a known issue and no data available if/when it may be fixed. Currently, car is running software v11. 1 2024. 2. 3.

27 Vehicle Speed Control problem

Failure Date: 02/01/2024

After making a right turn, the car accelerated automatically and drove onto the sidewalk. The driver was hitting the brakes and attempting to redirect the vehicle with the steering wheel but both components of the vehicle were locked, causing the vehicle to lose control and crash into several things on the sidewalk (flower pot, parked cars, building pillars). The Tesla is completely dead so we are unable to retrieve any data within the vehicle. The safety of civilians on the street as well has the driver and passenger of the vehicle were at risk due to the lack of control of the vehicle. Two weeks after the accident, Tesla sent out a recall notice in regards to autosteer which can increase risk of collision, but prior to this no notice/warning was in place. The police were involved and at the scene at the time of the event and a police report has been made. No messages were seen on the screen or on the Tesla app in regards to any car mode (autopilot, cruise control, etc. ) the vehicle could've been on, nor any warnings about risk of collision due to the recall.

28 Vehicle Speed Control problem

Failure Date: 01/26/2024

At 9:37 a. M. On January 26, I was driving on freeway 60. The three cars in front of me braked suddenly. I stepped on the brake quickly, but after I stepped on the brake for 3 seconds, the speed of the car still did not slow down, and it directly hit the rear of the car in front. Afterwards, on the Tesla app on, an alarm was displayed, saying that at 9:37, there was a problem with the steering wheel and brakes(unavailable) and also, there is a manufacturer recall number:tbd NHTSA recall number 24v-035; tc2024-027 (the manufacturer has failed or is unable to remedy this safety recall for my vehicle in a timely manner, I want to file an online complaint with NHTSA).

29 Vehicle Speed Control problem

Failure Date: 01/07/2024

The cruise control has been braking for no apparent reason, putting myself and the people behind me at risk. It also tried to stop at multiple green lights rather than continue driving. The his also outs me, my passengers and people behind me at risk. There were no warnings about this behavior. I have the latest update and will also contact Tesla about the issue.

30 Vehicle Speed Control problem

Failure Date: 01/05/2024

Car slams the brakes while on autopilot with no obstacles on the highway. Car speed reduced at least 20 miles for no reason. Weather was clear.

31 Vehicle Speed Control problem

Failure Date: 01/05/2024

While driving at hwy speeds in the #2 lane the #1 lane to my left was closed with construction cones. I was in the lane with cruise control activated and driving at approx 70 mph with flow of traffic. I had been in this lane for a few miles when all of a sudden the car rapidly decelerated approx 10-15 mph in a very short distance. I took control of the acceleration by quickly taping my brakes. Luckily there was no one behind me, as it could have created an accident risk. My only guess is the car interpreted the line of cones as a hazard even though they were not in my lane.

32 Vehicle Speed Control problem

Failure Date: 01/02/2024

I was driving on a 2 lane road with cruise control engaged (not full auto pilot). As I approached an intersection with an oncoming semi-truck, the vehicle slammed on the emergency braking system slowing from 60 mph to 45 mph in about 30 feet. I think it is called phantom braking. I was driving into the sun at 2:45pm.

33 Vehicle Speed Control problem

Failure Date: 01/01/2024

During highway driving, on two separate occasions that were two days apart, while using cruise control set to ~72mph the vehicle suddenly tried to stop. It quickly decelerated by ~25mph before I intervened by pressing the accelerator. There were no obstacles in the road and on the second instance there weren't any other vehicles in site (was in remote northern nh/vt). Had someone been driving behind me we very well could have been rear ended. I was driving with by wife and three kids and did not feel safe.

34 Vehicle Speed Control problem

Failure Date: 12/26/2023

I am writing to express my dissatisfaction with my new Tesla Model Y rwd, which I received on December 3, 2023. I have encountered two major issues with the vehicle and the customer service. First, I was promised by Tesla representatives that I would receive six months of free supercharging after delivery, as part of a referral program. However, this offer has not been activated yet. When I contacted Tesla, one of the supervisors told me that I was not eligible for this offer, because I placed my order on September 23, before the program started. This is unacceptable, as I was assured multiple times by Tesla agents that they would honor the offer and match it before delivery. I also offered to take back my self-driving capability which is available to me for free for the first 3 months. Second, I have experienced serious problems with the auto-pilot feature of the vehicle. I have used it four times briefly in the last month, and every time the car slowed down significantly when it was supposed to cruise at 50 mph. Twice, I had to avoid rear collisions by pressing the accelerator or the brakes. I reported these incidents to Tesla through the app, but I have not received any response or explanation. The most alarming event occurred on December 26, when I was with my family on a return trip from ikea in woodbridge, va. The weather was bad and the Tesla suddenly stopped on the road. I suspect that the front camera falsely detected an obstacle and caused the car to brake abruptly. These issues are not only frustrating, but also dangerous and potentially life-threatening. I am very disappointed with the quality and performance of the Tesla Model Y, as well as the lack of customer support and accountability. I request that Tesla either provide me with a satisfactory solution or compensate me for the inconvenience and risk that I have endured. I have a legal background and I am aware of my rights and remedies under the lemon law and other consumer protection laws.

35 Vehicle Speed Control problem

Failure Date: 12/17/2023

What component or system failed or malfunctioned, and is it available for inspection upon request? slowed down entering a driveway when car sped up on its own , forward collision warning/emergency automatic breaking did not warn or do any breaking. No sound or warning on the computer screen. I brake but the car still hit the post. I do not know what speed it accelerated to. I am not sure if autopilot kicked in but the car accelerated when I have already released the accelerator. How was your safety or the safety of others put at risk? yes - injuries sustained. Has the problem been reproduced or confirmed by a dealer or independent service center? when calling Tesla on Dec 23, 2023 - was told by the rep that ticket has to be filed but I was disconnected and I was not able to get through the lines. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? yes - car was totalled. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? I never saw any warning lamps come on as I always driven with distance. The camera was worked was worked on due to the wiper going on even when not raining on October 24 but the fix did not work. Once at the emergency room, trying to call Tesla or texting the no that responds when buying the car no longer accepting my text. The promise that when we get car accident, Tesla will call - no phone calls. All I received was text alert car suffered failure and was deactivated. I was in pain and not able to follow up and try to do report and look at pictures. . Today I just received a letter dated 2/8/2024 about recall no 23v-838 in the mail. But the car is gone. . . The software version it had is 2023. 27. 7. The tech guy came here to the house on oct 25, 2023 and checked everything.
