2024 TESLA MODEL Y Forward Collision Avoidance Problems

Incident Description (in my own words): We were driving southbound on [XXX] from New Hampshire back to Boston in our Tesla Model Y. Traffic became increasingly congested and slowed to a crawl. My wife was driving, and I was in the front passenger seat working on my laptop. As traffic built up, my wife became momentarily distracted and did not apply the brakes in time. I noticed, in my peripheral vision, the vehicle ahead of us—a truck—suddenly filling the windshield. At that point, I heard the forward collision warning alert, but it activated extremely late, essentially at the moment of impact. The vehicle did not automatically brake or stop, despite the low speed, close proximity, and clear visibility of the truck ahead. We collided with the truck in front of us. Damage was minimal (license plate damage and a small dimple on the front of the vehicle), but the safety concern is significant. Both of our Teslas are configured with forward collision warning set to “Early.” Under normal circumstances, this alert triggers frequently, sometimes conservatively. In this incident, however, the warning activated far later than expected, and there was no automatic braking intervention prior to impact. The front camera appeared clean and unobstructed. I am filing this complaint because this behavior undermines my confidence in the vehicle’s collision avoidance and automatic emergency braking systems. I am also filing a similar complaint for our Tesla Model 3. I am now anxious about whether the software will perform as expected in situations where driver attention lapses briefly—precisely the scenario these safety systems are designed to mitigate. I am requesting that NHTSA review this issue, as the system did not behave in a manner consistent with its intended safety function.

Autopilot was engaged and active at the time of the incident. The vehicle failed to detect a stationary piece of road debris (appearing to be a dropped vehicle part) located in the driving lane. The system did not provide any warning, slow the vehicle, or attempt an avoidance maneuver. The vehicle drove directly over the debris, resulting in damage to the lower exterior/body panel. Road and traffic conditions were normal. This raises concerns about Autopilot’s object detection and hazard response capabilities.

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.

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.

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.

While driving ~40 mph with no Autopilot or cruise control active, my 2024 Model Y suddenly braked itself from 40 → 0 mph for no reason. The road ahead was clear. I did not touch the brake. My 3-year-old was in the car. We were nearly rear-ended and could have been seriously injured. When I went to Tesla Service, the manager insisted I must pay a $270 diagnostic fee unless they “find a problem,” while also saying the incident was likely caused by “shadows.” This makes me believe they will simply say “no issue found” and charge me despite this being a severe safety malfunction. When I reached out to Tesla Customer Support, they stated it was a known issue. This poses a serious risk of rear-end collisions, injuries, or fatality, and Tesla is not addressing it.

On November 8, my 2024 Model Y suddenly came to a complete stop from about 40 mph while I was driving with no cruise control or Autopilot active. This was extremely dangerous — my [XXX] was in the car, and we were lucky no one was behind us. It put myself, my child, and others in the absolute risk of collision and injury. When I contacted the service center they said it sometimes happened due to "shadows" or "sun". They refused to run a diagnostic on the car for free and wanted me to pay for it.

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.

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.

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.

There was a sudden unintended acceleration and the brake did not work, causing a major accident. Car caught fire and door would not open. The car has completely engulfed. There were no warning lamps, messages or other symptoms prior to the failure. Vehicle has been inspected by insurance and police, but not by manufacturer.

After Tesla Berkeley performed an alignment on my 2024 Model Y on July 22, 2025, the car suffered a complete systems failure while driving on the freeway. Within minutes of leaving the service center, multiple safety systems shut down at once — steering assist, emergency braking, lane keeping, stability control, etc... all turned off, and the car went into manual mode. The vehicle became extremely difficult to control at highway speeds, forcing me to steer and brake manually without assist. Because the Service Center was closed that evening, I couldn’t contact anyone, so I drove back first thing the next morning (July 23) to report the issue. I was initially told the next available appointment was two weeks later, but I had to beg to be seen the same day because the car was unsafe to drive. Tesla redid the alignment and told me the car was fine. After reviewing the alignment reports, both the July 22 and July 23 data are mechanically impossible. The reports show rear camber changes from −1.8° / −2.3° to −1.5° / −1.6°, then to −2.0° / −1.8°, even though rear camber on a stock Model Y is not adjustable. This means the alignment equipment or calibration was inaccurate, and therefore the toe settings were also unreliable. The car was almost certainly released with incorrect rear toe, which explains the immediate handling instability and safety system shutdowns. A later independent alignment on October 13, 2025 (America’s Tire, Roseville) confirmed the correct geometry (−1.9° / −2.0°) and proved Tesla’s readings were wrong. Since the faulty alignments, my car developed severe inner-edge tire wear, and I had to replace all four tires prematurely. This incident involved a total system and steering-assist failure immediately after service, making it a clear safety hazard. Documentation (alignment reports and tire invoices) are available upon reques

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.

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.

FSD failed to break when another vehicle was making a right turn. I had to take over is a split second. I have dashcam footage but unable to upload in this form.

On [XXX], at approximately [XXX], I was driving westbound on the [XXX], just before the [XXX] and [XXX] off-ramp, with my wife and our [XXX] baby in the car. While in traffic, I noticed the regenerative braking system was not slowing the vehicle down adequately, despite having a clear and sufficient distance from the big rig ahead of us. As the gap closed, I slammed down on the brake pedal, but it felt abnormally stiff and did not respond with the urgency or force expected. The vehicle failed to stop in time, resulting in a rear-end collision with the big rig. Thankfully, we were not injured due to the speed of the accident. The breaks have not been inspected due to it being in the collision center There was an alarm but it sounded off too late and the car ended up colliding.

shortly after i purchased this car it began to put itself into park while the car was moving slowly and even when it was in car wash mode going through a brush carwash that requires cars to be in neutral. i reached out to tesla support to investigate and they explained this is a safety feature that engages if the driver leaves the seat while the car is not in park. i explained to them that in both cases i had been sitting firmly in the seat and there should have been no reason for the car to put itself in park and asked them how i turn this auto feature off. they said there was no way to turn it off. i explained to them that ALL automation features should be optional, they argued with me. came to find out some sensor in my driver's seat was malfunctioning. they took the car to replace the seat/sensor, but i reiterated that all these auto features should be optional and a consumer should be able to turn them off. my car was rendered unsafe to drive due to the malfunctioning sensor, i should have had a way to turn off the feature, i asked them to open a ticket with their engineers to add settings to turn off this automation feature. fast forward to 6/25/25, as i am pulling my car into a parking space at a store the car SLAMS itself in park, so hard that i thought maybe i had hit something hard with one of my wheels. i followed back up with Tesla support and am being told there is still no way for me to turn off this automation feature. no automation feature should EVER be hard coded into a motor vehicle. the risk presented by malfunctioning automation features is too great, and if i want to completely control every aspect of my car i should be able to, regardless of how much automation it is capable of. i am filing a complaint now because Tesla is clearly not taking these concerns seriously

I was driving at a speed of 60 miles per hour in rainy weather when the car’s emergency braking system suddenly activated. At the same time, the steering wheel locked due to the braking, and I completely lost control of the vehicle. The car spun multiple times before crashing into the center divider of the highway and finally coming to a stop. This was an extremely dangerous incident from a safety perspective. This was the first time such a braking malfunction occurred. The incident has not yet been investigated by the insurance company, and no warning or notification was displayed by the vehicle at any point.

After update 2024.38.2 they introduced a "Active Curve Assist" which can't be disabled while using the cruise control. This has caused the car to excessively brake (70mph to 45mph), a couple times while a vehicle is following resulting in a near rear end collision and has created dangerous situations

Incident Details: Date & Time: [XXX] Driver: My spouse, Purpose of Trip: Personal (heading to a nearby soccer park) Location: [XXX] Weather & Road Conditions: Clear weather, dry roads, normal traffic conditions Driver Safety: The driver was wearing a seatbelt at the time of the incident Incident Description: My spouse was driving to the nearby soccer park with the vehicle in FSD mode. Upon approaching a railway crossing, the signal was green, indicating it was safe to proceed. However, instead of maintaining a controlled speed, the car suddenly accelerated while attempting to cross. Before my spouse could take control, the vehicle struck the boom barrier, which was either lowering or had already lowered at that moment. The incident happened so suddenly that she did not have enough time to react and override the system. Fortunately, no injuries occurred, but the vehicle sustained damage to the front bumper, windshield, and frame. The unexpected behavior of FSD at a railway crossing raises serious safety concerns regarding its decision-making. Safety Concerns: I have been a long-time appreciative user of FSD, but this incident has shaken my confidence in the system. I now fear using FSD. Given the serious nature of this incident, I request an urgent review and response regarding my concerns, as well as coverage for the necessary repairs. Request for Investigation & Cost Coverage: Access to Vehicle Logs: I request access to the vehicle's telemetry and camera recordings to determine why this happened. FSD System Review: Please investigate whether this was an FSD-related miscalculation and what corrective actions are necessary. Cost of Repairs: As this incident was caused by an unexpected FSD action, I request Tesla to cover the repair costs for the vehicle and any associated damages.

The contact owns a 2024 Tesla Model Y. The contact stated that as he was driving forward at approximately 5 MPH after having stopped for a traffic signal his vehicle was crashed into the driver's right front fender by another vehicle. The contact stated the vehicle's front collision sensor did not detect the other vehicle. The contact stated that the driver's side front fender and the hood on his vehicle had to be replaced. The contact was not sure about the damage to the other vehicle, but there were no injuries. The police arrived on scene and wrote a report but he was not given the report number. The vehicle was towed to a local dealer and the body damage was repaired, however, the failure of the front collision avoidance sensor was not diagnosed. The contact stated that the failure reoccurred. The contact was driving at approximately 35 MPH at night when he crashed into the rear of a vehicle that was double parked on the street. The contact stated that the parked vehicle was in a poorly illuminated section of the street. The contact stated that his forward collision avoidance sensor had failed to engage and had not stopped his vehicle. The contact stated that the police were on the scene and had not issued a report. The contact had the vehicle towed to a local body shop, where the damage to the front bumper, grill, and headlights was repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 45,000.

I was driving on a three-lane highway (I-495) using the adaptive cruise control (autosteer) when I suddenly noticed the car to my right dangerously veering toward my vehicle. In an attempt to change lanes to the left, my car wildly overcorrected to the left, nearly sending me into the highway median, followed by another overcorrection to the right. The steering wheel felt almost uncontrollable. Luckily no collision.

When using FSD, I've noticed that on occasion at a red light, the car will start moving, albeit very slowly, a fraction of a second before the light turns green. I've assumed the car was watching the traffic lights from the other direction using its cameras. So on the [XXX] when this happened, and the car started moving I let it go thinking the light was about to turn green. But I was shocked that the car drove through the red light. Admittedly there were red lights in all directions. I know I'm supposed to be keeping control but it was so shocking that by the time I reacted the car was already in the intersection so I let it go. I downloaded a recording of it. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I continue to get completely FALSE forward collision warnings. Part of this is because my front camera housing keeps fogging up and over the past 529 weeks I’ve gotten a half dozen false FCWs. When these faulty alerts occur, a loud audible beeping is heard and red alerts are displayed on the screen. These faulty alerts are dangerous distractions, causing panic, fear, and uncertainty in the driver, causing them to take their attention off of the road while they assess what just occurred. This is a critical flaw in the functionality of Tesla vehicles that the company has refused to address. This also makes me insurance rate spike way higher and I’m getting charged extra for this.

Tesla has told me the AP4 computer has failed in my car which has resulted in them having to replace it. I had this issue start on 1/12, and I scheduled the earliest appointment available for 1/30. They did not offer me a rental or any assistance during this time, and I need my vehicle to commute to work and conduct other essential activities. It has just over 1,000 miles on it and is ~3 months old now. This issue impacts: backup camera, emergency braking, blind spot detection, lane keep/centering, assisting with parking, automatic high beams and wipers, cruise control/ adaptive cruise control, Vehicles built in GPS to be stuck at one location every time, has made my touchscreen not automatically brighten or dim, my auto dimming mirrors be too dim in most driving conditions, constantly fail to install system improvements and safety updates, and because my vehicle keeps trying to do this, it has caused increased battery drain as well. This has increased the safety risk of my vehicle tremendously, and i have received no reparations for it.

None of the cameras work in the Tesla. Unable to use any safety features. No reverse camera. Any adaptive cruise control, safety features are all disabled. Two months to get it repaired and serviced.

Back in late November 2024, Tesla pushed an Over-The-Air (OTA) update to my 2024 Tesla Model Y. Immediately after pushing this OTA, all of my car's cameras stopped working (INCLUDING my rear or "backup" camera). This is in violation of federal law as all new vehicles are required to have a backup camera. Additional safety-critical items were also impacted: the rear-view and both of the side mirrors remain tinted to the darkest level, reducing my visibility. The side mirrors are also tilted in the "downward" position, making lane changes incredibly difficult. Since the front-facing and side-facing cameras do not work the vehicle's forward and side collision detection systems are inoperable. The vehicle suffers from additional failures (GPS navigation, Maps, Autopilot, among many others). I have presented these issues to Tesla and they have continously pushed out my repair date. I have also asked for a loaner vehicle due to the failure of the car's safety systems (some of which are federally mandated!!). Tesla has ignored my pleas for a loaner vehicle and has also remained silent when I have repeatedly asked to return the vehicle under Washington State lemon laws. My safety and the safety of others have been put at grave risk due to the backup camera and collision detection cameras not working. Tesla has NOT inspected the vehicle as they continuously push my service date further out. No obvious warning lamps, messages, or other symptoms appear. The user doesn't know these federally-mandated safety features are inoperable until they put the car in "reverse" or attempt a lane change.

Park assist error message when put car in reverse. No visualizations on display. Early collision not working. Several times (not in this instance) backup camera has been black and does not show an image. Sentry system error message. FSD offline. (may not be a safety issue but wanted to provide information as it would show other errors in the system affecting safety) I have a scheduled appointment with the service center in February.

Around the end of November, my 2024 Tesla Model Y's cameras stopped functioning. The sensors for blind spots and possible collision prevention stopped working. The GPS was also not working, the car believes it's been in the same spot for over a month. The lights of the car also do not work as promised, as now I have to manually turn them on on my dashboard and it goes on and off. I have been trying to get into Tesla to have this fixed but the appointment keeps getting pushed out due to the part that needs to be fixed not being in stock. I brought my car into Tesla for them to confirm that it is the part that is missing and that is the case but they couldn't fix it because they don't have the part. It's been over a month and my date was pushed out again, probably the sixth or seventh time. Tesla claims that there will be a software update that will fix this issue, however, my car is not updating and won't even accept a software update.

I initially visited the Milford, CT Tesla Service Department and communicated through the Tesla Ap on 12/14/2024 regarding my 2024 Tesla Model Y, which has only 2,357 miles on it. The car's cameras, sensors, & navigation stopped working, making driving unsafe. Now, the bright lights do not go on. The vehicle's camera/sensors are critical for safe operation. Tesla said the car may need a new computer, but they have none in stock. They texted me that they have many people facing the same issues.

According to Tesla the AI4 computer experienced an internal short circuit. This has rendered all cameras including backup camera, GPS, parking sensors, and automatic wipers inoperable. The visibility out of the vehicle is very poor to the rear without the backup camera. Parking without the rear camera and parking sensors is difficult. Not having physical controls for the wipers makes turning them on/off and changing speeds difficult, causing a lot of drivers distraction.

Tesla Full Self Driving v13.2.2 attempted to make a left turn while having a red light. The vehicle successfully came to a complete stop due the red light but once traffic cleared the intersection it attempted to proceed with the left turn while still having a red light. I immediately took over preventing the car from entering further into the intersection.

Around Dec 16 all cameras in my 2024 Model Y Tesla stopped working and it has not worked since that date. This affects many systems, the most important of which is that I now have no rear backup camera. I believe vehicle manufacturers are required to have functioning back up cameras. I notified Tesla service on 12/16 and was told there was a known computer hardware problem which would cause my incident. Tesla service told me they were unable to obtain the needed computer replacement for a month at least. They informed me there was no safety risk, but I disagree since I don’t have a functioning back up camera, nor lane change camera assistance. Also the display panel is very dark and impossible to read most of the time, posing another safety concern. Why has Tesla not issued a public statement about this problem, and why has NHTSA not mandated a formal recall?

The FSD feature for which we have paid in full to Tesla does not work. No cruise control and no Assisted Steering Control or Cruise Control works. As per their Service Department, AP4 Car Computer has internal short and camera can not communicate for above mentioned features.

Vehicle Information: • Make: Tesla • Model: Model Y • Year: 2024 Description of the Problem: After a software update pushed by Tesla, the AP4 computer in my 2024 Tesla Model Y shorted out, causing a complete failure of all systems controlled by this computer. The following safety-critical and driver-assist features have become non-functional: Cruise Control (adaptive or otherwise) Back up Camera Forward Collision Warning Lane Departure Warning Lane Keeping Assistance Blind Spot Warning Parking Collision Warning Full Self-Driving and Auto Park features Cameras required for Autopilot functionality Additionally, because the GPS system has failed, the vehicle’s Navigation system is inoperable. This impacts Tesla’s unique route planning feature that sets up Supercharger stops during long journeys. Without a functioning navigation system, I cannot properly plan my travel or locate charging stations, which severely affects the usability of the vehicle. Safety Concerns: The failure of these systems, especially safety features like forward collision warning, lane keeping assistance, and blind spot monitoring, puts both the driver and others on the road at risk. Losing access to safety-critical functions after an update is unacceptable and poses a serious danger to vehicle occupants and surrounding traffic. Incident Details: • The issue occurred immediately following a software update. • Tesla pushed the update remotely without providing any warning or indication of potential risks. • The failure appears to be related to a hardware short in the AP4 computer, directly caused or exacerbated by the update. Desired Outcome: • A thorough investigation into Tesla’s software update process and its effect on vehicle hardware and safety systems. • A resolution that prevents similar failures in other vehicles and ensures system updates do not compromise vehicle safety or critical functionality.

Hello , I just bought the new Tesla Model Y 2024 in the October and all of a sudden all the driver assistance programs are not working, including the Rear Camera(Reverse camera) I took it for the service on December 4th and they fixed issue on December 5th. After few days on December 13th the same issue happened again and Tesla service center is saying I need to wait till February 20th 2025 for the repair. All cameras are not working in the car, it does not show any backup camera, No forward collision warnings or no lane change assist Tesla is not considering this as a safety issue I am including a chat summary with the service center via PDF file. I have included previous repair invoice also when the same issue happened on 4th December

Cameras stopped working which made all of the safety functions and GPS stop working as well.

The car lost all ADAS functions, and GPS on the onboard navigation system. In addition. it can't use regular cruise control and it does not have rear view mirror blind spot warning capability any more. This all happened when the car attempted to install the "holiday" updated from Tesla automatically around 11/29/24 .

On 12/16/2024 my vehicle received software update 2024.39.15, after installing the update i went to the grocery store and noticed nothing was working in the car except basic driving functionality. cameras were showing up as a black screen. TACC, aurosteer and FSD supervised were no longer working as well as AEB,FCW,BSM,LDW,LKAS and the gps had me in the middle of the ocean, headlights on during broad daylight. I informed a service center by my home and they simply didn’t care, i took it to another service center 50 minutes away and they took two days to do repairs and diagnostics, i was told the computer had shorted out and the technician replaced the car computer and AI4 (HW4) computer system which runs safety features. A software update physically pushed from tesla should not be shorting out computers on its vehicles, i heavily rely on the cameras and safety features since living in a state where nobody knows how to drive (lol). I hope my vehicle is fixed and this issue doesn’t persist anymore.

AP4 computer failure has led to navigation, cameras, blind spot monitoring, lane departure and other systems being inoperable. Tesla has stated they don’t have the parts to fix and have pushed out my service repair time twice already. Issue reported on December 4th, since then no time table for repair has been given. Tesla keeps stating the car is operable, leaving out the facts it’s dangerous to drive due to small rear windows and blind spots based on the cars design to work with operable cameras that give the drive clearer angles to view.

They advertise it as a computer failure. The cruise control doesn't work, none of the cameras displays, causing me to hit the lawnmower in my garage. Other functions as navigation, range prediction, and automatic light/dark display switching don't work either.

Navigation is frozen. No cameras work. No full self driving features work. No cruise control.

My New 2024 Model Y Tesla is having a computer failure - no navigation / GPS (stuck at last address when issue occurred) and no cameras (including rear camera). With limited rear windshield visibility and no backup camera functionality, we've been put in dangerous situations. They keep pushing out the service dates waiting on new parts / computers. I found this article that details the widespread issue and parts shortage. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The display went black. I reset it. It came back but none of the cameras work.

All safety sensors appear to be out of service. Navigation is stuck at one location and is not working. All cameras, including backup, are out of operation (only shows dark screen). Back up sensor does not work. This issue has been ongoing for 1 month on a brand new vehicle. Tesla service center has no ETA on resolution. Service appointment has already been pushed back to next year (Jan 2025).

No cams working, no reverse cam, no 360 view, no auto wipers, no regular cruise, no FSD, no ASS or dumb summoning, no emergency braking, no park assist and for some reason no navigation

My computer has failed. No cameras work including the rear camera. It no longer has cruise control, keeps me in my lane, or has blind spot detection.

Tesla has told me the AP4 computer has failed in my car which has resulted in them having to replace it. I had this issue start right around Thanksgiving. I scheduled the soonest appointment available for 01/03. Not offering me a rental or anything on my brand new '24 Tesla. It has just over 1,000 miles on it and is ~1 months old now. This issue impacts: emergency braking, blind spot detection, lane keep/centering, assisting with parking, automatic high beams and wipers, cruise control/ adaptive cruise control, back camera, Vehicles built in GPS to be stuck at one location every time, has made my touchscreen not automatically brighten or dim, my auto dimming mirrors be too dim in most driving conditions, constantly fail to install system improvements and safety updates, and because my vehicle keeps trying to do this, it has caused increased battery drain as well. This has increased the safety risk of my vehicle tremendously... Tesla has not seemed to publicly acknowledge the issue yet either.

Tesla has told me the AP4 computer has failed in my car which has resulted in them having to replace it. I had this issue start right around Thanksgiving, specifically [XXX]. I scheduled the soonest appointment available for 12/13 however Tesla contacted me and moved my appointment because they stated that the part was unavailable at this time and should be delivered by 01/20/25. Not offering me a rental or anything on my brand new '24 Tesla. It has just over 2500 miles on it and is ~2 months old now. This issue impacts: emergency braking, blind spot detection, lane keep/centering, assisting with parking, automatic high beams and wipers, cruise control/ adaptive cruise control, Vehicles built in GPS to be stuck at one location every time, has made my touchscreen not automatically brighten or dim, my auto dimming mirrors be too dim in most driving conditions, constantly fail to install system improvements and safety updates, and because my vehicle keeps trying to do this, it has caused increased battery drain as well. Additionally, the vehicle came to a stop on the highway when my wife and I were in the car on the night of [XXX], forcing us to perform an emergency pullover and abandon the car 22 miles north of Rochester, MN overnight.

Bought my Tesla Model Y on [XXX]. Exactly one month later on [XXX] I start my car to find that none of the cameras are working. This means Autopilot, cruise control, rear camera, blind spot monitoring and many more safety features are completely down. In addition the GPS does not function meaning my car is not trackable and Maps don't work, another safety concern and main reason we bought the car. This is a widespread issue that Tesla Service Centers have been informed about from Tesla that it is a bad computer that needs to be replaced - in a 1 MONTH old car. My only option is to wait for a computer to be assigned to me which is at earliest on January 21st of 2025, almost 6 weeks without a fully functioning brand new $46,000 Car with only 1400 miles on it. Tesla are also unwilling to make any kind of restitution such as a loaner car, or a refund for the Full Self Drive and Connectivity packages I just purchased but cannot use as my car is broken.

All cameras stopped working. With this, all safety features are not working. I can’t see to back up at night. No collision avoidance, no lane departure warning, high beams don’t stay on, turn signal doesn’t stay on. It has been two weeks and Tesla has no fix. There was no warning, just noticed it one day as I was driving it and was very dangerous in dark snowy conditions. I called Tesla service immediately and they gave me an appointment for following week. Then next day I got message from them that there are a large number of vehicles having the issue and they said they don’t have a fix for it and moved my appt out 7 weeks. I have gotten no help from them and I told them I don’t feel safe driving the car. They have not provided another car.

After latest Tesla software upgrade, all cameras and GPS stops working. All automatic functionalities of the car stops working without cameras, and it is really unsafe to drive, for example back up the car since the physical rear view mirror is very small, and car is naturally designed with those cameras to function properly.

On Nov 23, 2023, I was reversing car from my driveway in the morning. Car started giving warnings with issue on all its cameras. While reversing car, it will give error that rear view camera not available. While giving left/ right turn signal, it is showing blank screen for that view. All other safety features like blind spot detection, lane assist are not working at all. I also started getting error message that emergency brake is not available. I have been contacting them for immediate repair/ provide loaner car from same date (11/23/2023). Earliest appointment date given is Dec 11, 2023. This is not acceptable at all. It is very dangerous to drive the car without those safety futures. I am also concerned on any other issues which it has not reported. I don't feel safe to drive the car.

The computer is not working which connects to the forward collision warning system, navigation, and all safety when it comes to driving. I am still waiting to hear back from Tesla about the problem and haven't had a resolution.

Vehicle cameras stopped working. Navigation stopped working. Screen also stopped working for a time. Was able to get it back on but it went off multiple times since. If I can't see the screen, I can't tell how fast I'm going to do anything else. Cameras control many of not all of the safety systems. So those are all inoperable. Issue is being reported across multiple forums all over the internet as "short in ap4 module."

All safety features and cameras on this vehicle are currently disabled. Specifically, the following functions are not operational: Forward and parking collision warnings, Blind spot warning, Lane departure and lane-keeping warnings, Rear cross-traffic warning, Self-driving capability, Adaptive cruise control, Navigation system, Location tracking, Sentry mode, Premium connectivity features, Reverse camera, Front and side cameras. Additionally: the headlights remain on continuously during daylight hours. The interior control panel screen and the side and rear mirror displays are stuck in night mode.

While driving between 50-55 mph the Tesla applied emergency breaking even though there was nothing in front of us and no risk of accident. The car went from 55 to about 5-10mph in the matter of a second. We are lucky no one was directly behind us or it would have led to a high speed rear end accident.

#Issue Description I experienced an issue with Tesla’s Full Self-Driving (FSD) system when a trailer hitch was attached to my vehicle. From what I observed, the FSD system appeared to detect the trailer hitch as an object in close proximity to the vehicle. This caused the vehicle to accelerate rapidly to the FSD maximum speed of 85 MPH, regardless of the road conditions or posted speed limits. This issue occurred when the lane markings were visible, but the hitch obstructed the rear camera’s view. On the FSD display, this obstruction was represented as a persistent “cloud” following the vehicle. I attempted to adjust the maximum speed limit manually to mitigate the acceleration, but this did not prevent the behavior. Each time I engaged FSD, the car would accelerate rapidly, even in situations where such high speeds were not appropriate for the road conditions. # Steps Taken to Resolve the Issue I covered the rear camera, which allowed FSD to function normally and prevented the rapid acceleration. The “cloud” visualization on the FSD display also disappeared once the camera was covered. # Trailer Mode Tesla offers a “Trailer Mode,” but I did not enable it since I was only using a hitch without towing a trailer. My understanding is that FSD does not operate in Trailer Mode. # Reference: This issue has been reported by other Tesla owners, as discussed here: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have had multiple incidents of “phantom braking” when using traffic aware cruise control and auto steer. It usually happens on one lane state highways with opposite direction traffic, sometimes with turns or hills. The vehicle has slammed on the brakes without warning, sometimes the warning tone also sounds. Each time there was absolutely no danger, nothing abnormal. On a couple occasions there was traffic behind me, and it must have scared them. They probably thought it was a hard brake check. If I wasn’t able to quickly over ride the braking with the accelerator it very easily could have caused an accident. On two occasions my pregnant wife was in the car and it scared her very much. I am personally afraid to use it now, knowing it’s going to slam on the brakes is nerve wracking and UNSAFE. Tesla does not seem to care about addressing the issue, rather putting all eggs in the “full self driving” basket instead of improving this very obvious safety defect. From reading online forums it seems to affect just about everyone. I’m hoping their engineers address it and they release a software update correcting it, but as mentioned above it doesn’t seem to be on their list of priorities; the problem has been happening for several years now and has resulted in at least one known fatality. Hopefully the NHTSA can light a fire under them and have this scary safety defect addressed.

My car slammed on the brakes on the highway this morning at 75 mph. A box truck was following me but thankfully he didn't hit me. I was in what Tesla calls Traffic Aware Cruise Control (TACC) at the time and quickly brought the car out of TACC and hit the accelerator to get me back up to speed so I didn't pose a danger to other drivers on the highway. I dont know exactly how much my car slowed, but it was enough to throw me forward in my seat. There were no vehicles in front of me at the time. This was a classic example of "phantom braking", which is talked about a lot in the Tesla community. This is my 2nd report of phantom braking to the NHTSA.

In a 90 mile drive I experience phantom breaking 4 different times. No car was in front of me, in fact nothing at all was in front of me when my car slammed on the brakes 4 separate times. One time there was a car somewhat close behind me. I also twice experienced audible warnings and flashing alarms to take control immediately of the car when my hands were on the wheel and I was already in control of the car, it was alarming and shocking to get these alarms while already in control and driving. I believe this car, as currently configured, can pose a danger to other drivers on the road.

I was driving on [XXX] across Kansas and my car suddenly braked hard. I was in cruise control when it occurred. I was not in automated driving mode as I don’t have that feature. This happen once before earlier this year on a two lane highway when a truck was coming toward me in the opposite lane. This time I was on a 4 lane highway with a large dividing median and there were no cars near me. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While using adaptive cruise control the vehicle regularly decelerates for no reason and without warning "phantom braking". I experience this about once a week, but experienced it multiple times on a longer drive this weekend. The unexplained abrupt braking could result in being rear-ended by another vehicle.

On multiple ocassions when using adaptive cruise control the vehicles slams on the brakes without warning and for no reason and brings car to a near standstill in the middle of traffic unless I slam the accelerator down and fight the car. Engineers from Tesla inspected the vehicle and said everything was working normally, but it continues to malfunction and almost causes accidents with cars behind in traffic having to slam on their brakes as well.

I was driving on a street at the speed limit there were no cars in front of me and behind me thankfully the car just braked very hard suddenly for no reason and I lost complete control over the vehicle after the car came to a complete stop I was able to continue driving. Thankfully there were no cars behind me because if there were I don’t even want to imagine the accident I could’ve caused aside from this the breaking was so hard that my whole body hurts and I am afraid to drive the vehicle as I do not know when to expect this breaking since it can happen so suddenly at any time.

I was parking the Tesla Model Y at very low speed, when there was a sudden unintended acceleration. The car banged against the wall of a building and was severely damaged. My family - wife and two children were in the car.

I was driving and going about 50mph and there was no other car near me. Suddenly the car slammed on its brakes. Dropped to probably 10mph. My mom and I were both wearing seatbelts but our heads were thrown forward. My neck and shoulder are sore and stiff today now. There were dark skid marks in the road ahead of us and I believe the car saw those and broke because of them. If there had been a car behind us, we would have be rear ended. There were no warnings beforehand. When the car broke, lights flashed and there was also an alarm. The vehicle has not been inspected by police or manufacturer.

1st incidence: The car with full self driving mode self-changed to shoulder lane on [XXX] for unknown reason. I had to steer back to my lane to avoid hitting the FWY divider. 2nd incidence: with autosteer/cruise control mode, the car self changed to left lane, again I quickly guided the steering wheel back to my lane to correct the action and it caused a car accident.

The incident occurred on [XXX] at [XXX] PST in Sammamish WA, where my car (2024 Tesla Model Y) incorrectly enabled Automatic Emergency Braking , and unexpectedly applied brakes when I was traveling at 45 mph on an empty road. The sudden braking reduced the speed of my car to less than 15 mph in a span of 2 seconds and eventually brought the car to a halt . I strongly believe this was done in error due to a system malfunction, as there was no potential cause of a collision given there were no incoming vehicles or any vehicles ahead. There were also no pedestrians or any objects such as animals or wildlife on the road. One this incident occurred, an alert with code “APP_W050” appeared on the car screen. (photo attached). Due to this abrupt unexpected braking, It caused a significant treat to my safety, as I could have potentially lost control of the car and slid off the road into a ditch or another vehicle traveling behind me could have potentially collided with me in the rear end.

During my trip, traveling at speeds ranging from ~30 to ~75mph my car suddenly and with no advance warning braked to a full stop, four separate times. I was not using cruise control or any driver assisted features. There were no obstacles in the road. I did not get in an accident because there were no other cars near me on the two different roads I traveled on.

My family and I were on [XXX] heading toward Sacramento when the Tesla Y suddenly braked. We were using autopilot and going around 70 mph. The car was trying to pull a full stop in the middle of the freeway! I quickly disengaged the autopilot and stepped on the pedal to speed back up. I'm guessing the Tesla saw a hazard on the road and put on the brakes. The problem is there were no hazards. Our safety was put at risk because we could've been reared, and it could've caused a pileup. Luckily, it was early Sunday, and there weren't a lot of cars on the road. We stopped using the autopilot immediately, so the problem has not been reproduced. We have an appointment with Tesla in four days. I will be reporting the incident to them. I'll ask for an inspection then. There were no warning lamps or other symptoms prior to the sudden braking. It was a very jarring experience. I have my kids in the back seats.

This is my fifth Tesla, so i.am very familiar with the Self Driving feature which is mostly good. However, recently I got a Model Y and with in 24 hours I was rear-ended on the freeway! I had the car in Full Self Driving mode (FSD)! For some reason it just braked hard in the middle of my driving however, traffic was backing up. I injured my lower back and neck and I'm now having to go in for therapy and schedule a CAT scan. Luckily the person behind me was fine. After the incident I downloaded the zip disk which records incidences. The car had documented pre and post accident! But the actual incident there is no record... almost like it got wiped out!?!

The vehicle would not stop and ran into the back of a friend. I am not safe in the vehicle as we were in a parking lot no way I could’ve reached top speed.

I was driving down the highway with my wife and baby at about 65 mph. I was using regular cruise control with no one in front of me when all of a sudden, the car braked extremely hard. Luckily, the car behind me was far enough back to switch lanes and pass me. If it was closer, this could have resulted in a highway accident. The car stopped braking maybe around 30 or 40 mph. I may have it recorded in the Tesla camera system since I pressed the save button approx 4 min after it happened. I also scheduled a service call with Tesla that will hopefully happen on may 7th

My wife and I purchased a model Y 2024 just a few weeks ago. We have had multiple experiences when using cruise control where the car inexplicably slows down rapidly when there are no vehicles in front of us decelerating.

While using autopilot with beta self driving installed and stopped at a traffic light, left or right turn traffic signal turning green causes car to move into oncoming traffic (moves straight through intersection).

While using Autopilot or Beta self-driving - when a Minimum Speed Limit sign is detected on [XXX] in Georgia, the system usually reduces to the speed of the vehicle to posted minimum speed (40 miles an hour) instead of maintaining current speed limit.

While driving to work, using FSD, the autopilot steered me into the path of an overtaking vehicle moving at about 20 mph faster than my vehicle. By quickly taking over steering and speed control, I was able to avoid a collision. A couple miles further down the road, the car could not decide on which exit lane to use, and weaved between two possibilities, probably alarming and angering drivers behind me. Again, I had to take over control. Taking over speed and steering control was necessary two more times in my 25 minute trip, most of it on well-marked multi-lane highways. Of the four incidents, only one would have resulted in a serious high speed collision, had I not taken over very quickly. Having coached robotics competitions, and piloted aircraft with autopilot, it is my opinion that the FSD (SUPERVISED) software is at alpha stage in development (not yet up to beta stage, at which it could be safely released only to select skilled drivers, with suitable disclaimers and warnings) . At delivery, no introduction to the car's controls is provided, so customers are on their own regarding finding out, by trial and error and the occasional potentially lethal collision, how to safely drive the vehicle with FSD engaged. The manufacturer should be required to instruct all customers on the very high level of vigilance required to operate with FSD engaged.

Unknown. Drove car in front of garage. Car came to a full stop. About to put car into reverse from drive in order to back into the garage, when car suddenly accelerated forward. Turned wheel sharply to the left in order avoid hitting neighbors fences. Vehicle traveled in an arch and collided with a tree next to an fence and stopped.

We purchased a 2024 Tesla Model Y approximately one month ago. We have experienced multiple occurrences (10-15) when Traffic Adaptive Cruise Control was engaged. Our car suddenly braked for no apparent reason. Last night, while traveling at 65 mph, on a four lane major highway, it happened again, nearly causing a rear end collision. We are hesitant to use cruise control because this feature (T.A.C.C.) is built into cruise, no way to separate it. After researching online, we discovered this is not a new or unusual event and has been reported by hundreds if not thousands of Tesla owners, dating back at least 3-4 years (if not longer). There are no warnings prior to the event. The car suddenly slams on brakes in what seems to be a “panic stop.” We understand a record of these occurrences are recorded and available from Tesla at your request. We have registered a complaint with Tesla as well.

Car decelerated drastically to a low speed when driving on the highway using cruise control.
