2025 TESLA MODEL Y Forward Collision Avoidance Problems

The vehicle was in supervised full self driving on the turnpike, when all of a sudden it darted out of the lane into th grass hitting a guard rail.

SUMMARY OF SAFETY DEFECT: Multiple critical safety systems randomly disengage without warning while the vehicle is in operation, creating an immediate crash hazard. DETAILED DESCRIPTION: For approximately one month, my vehicle has experienced intermittent, unpredictable failures of multiple safety-critical systems while driving. These failures occur randomly during operation and include: Regenerative Braking System Failure (PRIMARY SAFETY CONCERN) Lane Departure Warning System Failure Automatic Vehicle Hold System Failure Traction Control System Failure Automatic Emergency Braking System Failure Electronic Stability Control System Failure SAFETY HAZARD ANALYSIS: The sudden disengagement of regenerative braking while driving poses an acute collision risk. Tesla vehicles are designed with regenerative braking as the primary deceleration method when releasing the accelerator. Drivers develop muscle memory and expectations based on consistent vehicle behavior. When regenerative braking unexpectedly disengages mid-drive, the vehicle's deceleration characteristics change dramatically and without warning, creating a dangerous situation where: The driver expects normal deceleration upon releasing the accelerator The vehicle instead continues at speed, requiring sudden brake application Reaction time is insufficient to compensate for the unexpected behavior change Rear-end collisions or other crashes become likely, particularly in traffic Similarly, the Automatic Vehicle Hold feature unexpectedly disengaging means the vehicle may roll when the driver expects it to remain stationary at traffic lights or stop signs. PATTERN AND FREQUENCY: These system failures occur randomly and unpredictably while driving. The issues sometimes resolve after: Restarting the vehicle Restarting the cent However, the failures recur without warning during subsequent driving.

INCIDENT REPORT – TESLA Y – UNINTENTIONAL ACCELERATION SATURDAY NOVEMBER 29, 2025, APPROXIMATELY 2:40 PM On the above-referenced date and time, we were returning home with the intention of pulling the car into our garage, an activity performed over a hundred times in the one year we have owned the car. Because of the need to back in to allow the car to be charged, the following procedure is adhered to: 1.Disengage self-driving (if it was being used) in the street prior to entering the courtyard for residence. 2.Pull forward three-quarters of the way into garage (since the residence is the last on the courtyard and the car cannot be pulled beyond the garage opening to directly back in). 3.Place car in reverse and slowly perform K-turn to back into garage. On the date in question. The following anomalies occurred: 1.After placing the car in reverse (action 2), instead of starting to back out, the car lurched forward. The brake was immediately applied and the car stopped about a foot before hitting the garage wall. 2.The brake was applied again to assure self-driving was disengaged and proceed with action 3. 3.Car was placed in reverse and accelerator was lightly pressed to slowly back out of garage. Rather than slowly back out (as was done hundreds of times) the car immediately accelerated and rapidly gained speed. 4.The brake was applied to stop the car but could not overcome the acceleration (pictures of skid marks were taken). 5.In order not to directly hit the wall located across from garage, Car steering wheel was turned to minimize any direct contact ( skid marks will show turn). 6.Car came to a stop when it hit the wall causing significant damage to the car and causing damage to the wall (pictures can be forwarded).

My vehicle experienced multiple safety system malfunctions before a minor collision occurred. While driving, the car displayed warnings indicating that traction control had been disabled, followed immediately by a warning that the automatic vehicle hold/brake hold was disabled. These failures happened before any impact. At the same time, the vehicle’s cameras were not functioning correctly, and the vehicle did not provide any forward collision warning. The automatic emergency braking system also did not activate. Because these systems failed, the vehicle did not warn, slow down, or brake to avoid a collision. After the collision, the vehicle showed several additional safety system failures. These included automatic emergency braking unavailable, and repeated safety restraint system faults affecting both the front left and front right restraint systems. The airbags did not deploy even though conditions suggested they should have, and afterwards the vehicle displayed persistent airbag and seatbelt system error icons. The restraint system appears to have gone offline. The vehicle is currently unsafe to drive due to failures in braking, traction control, perception/camera systems, forward collision warning, automatic emergency braking, and the airbag/restraint systems. These failures occurred before the collision, contributed to the collision, and continued afterward. The manufacturer’s service center has declined to provide towing or a loaner or rental vehicle while the safety defects are being investigated, which will take about 30 days.

Self driving was maintaining vehicle. Looked at roadway before reaching down to passengers side for water bottle. The weight shift in the seat turned the self driving off immediately while turning sharp left. The Tesla Model Y crossed the left interstate lane barely missing an 18-wheeler. Drove 80mph in the central ditch, branches, and rocks. Car was still in drive, and rolled up to roadside which was covered in dust. The two eighteen-wheelers that I cut off then Drove away, and drove tesla to next exit to see damage.(dashcam footage available.)

On November 10, 2025 while my 2025 Tesla Model Y was being driven, in Miami, Florida, around 2:55–3:05 PM, the brakes failed completely. Despite firm brake pedal pressure, the vehicle did not slow down or stop as expected and continued forward until a collision occurred. The brake pedal felt normal with no loss of resistance, but the car did not decelerate as expected. No forward collision warning (FCW) or automatic emergency braking (AEB) activated prior to impact. There were no audible or visual alerts displayed before or during braking. After the collision, the vehicle’s screen displayed messages stating “Airbags Deployed” and “Automatic Emergency Braking is unavailable. Feature may be restored on next drive.” However, the airbags did not deploy. A burst of white particulate dust, consistent with airbag propellant or deployment powder, was released inside the cabin. None of the vehicle’s cameras recorded the incident; there is no Dashcam or Sentry Mode footage from that time. At the same time, the cell phone, which was actively linked to the vehicle through Bluetooth and the Tesla app, stopped transmitting location data through the Life360 app for a few minutes. This may indicate a coinciding electrical or data interruption affecting both the vehicle and connected devices. This incident placed my families safety and that of others at serious risk. Multiple safety systems appear to have failed simultaneously, including the braking function, forward collision warning, automatic emergency braking, camera recording systems, and airbag deployment.

My model Y tesla deployed the emergency brake system while I was driving the vehicle. There wasn’t any vehicle or anything in the way for my tesla to do the emergency brake. I did get whiplash from the incident and been experiencing neck and shoulder pain. Lucky I was able to get an appointment to service my Tesla the next morning but at this moment they haven’t given me any diagnostic. My Tesla did have a message related to the camera that showed up like 5-10 minutes prior to the incident but the warning message disappeared after a few seconds.

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!

Vehicle Autopilot settings with default settings, 1) traveling marked highway speed of 75 mph, vehicle detects something in either the lane to the right or left will slam on the brakes possibly causing a rear end collision, 2) traveling at marked highway speed of 75 mph, vehicle detects curve signs either to the right or left will slam on the brakes possibly causing a rear end collision, 3) traveling in town at marked speed of 40 mph, vehicle detects a vehicle turning at a safe distance for the speed either right or left will slam on the brakes possibly causing a rear end collision. Vehicle Autopilot settings: Forward Collision Warning “OFF”, Lane Departure Avoidance “OFF”. Emergency Lane Departure Avoidance “OFF”, Automatic Emergency Braking “OFF”, Obstacle-Aware Acceleration “OFF”, will remain set for the current drive without any of the above safety issues. Next drive the Automatic Emergency Braking “ON” and the above safety issues can happen. Tesla must make immediate software improvements in the Automatic Emergency Braking system and/or allow continual “OFF” setting disabling of the Automatic Emergency Braking system.

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.

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.

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.

While driving westbound on Lee Jackson Memorial Highway (U.S. Route 50) after passing the intersection with Stonecroft Boulevard in Chantilly, Virginia, the Autopilot system on my Tesla Model Y malfunctioned. Without any warning or obstacle in my lane, the vehicle suddenly and sharply veered to the right, directly toward two vehicles traveling in the adjacent lane. I was holding the steering wheel at the time and was able to immediately countersteer to prevent a collision. There were no audible or visual warnings from the vehicle before or during the incident. The Autopilot system did not display any messages or alerts, and no braking or turn signal was engaged by the system. The lane shift was abrupt and uncommanded. The dashcam footage clearly captured the incident, and it is available for inspection upon request. To my knowledge, the issue has not yet been reproduced or inspected by the manufacturer or service center. The vehicle has not been examined by police, insurance representatives, or others at this time. This unexpected maneuver created a serious safety risk for myself and nearby drivers.

1. Brake I used the FSD all the way from the New Asian Market (Charlotte, NC) to the T-section of [XXX] and [XXX] (Columbia, SC), then changed to driver control and turned to [XXX] (home). Entering the garage, when arrived at the parking spot, I released accelerator pedal and pressed the brake pedal, the car did not stop but pushed forward, and hit a wooden shelf, BBQ grill and the drywall. The car, shelf, BBQ grill and the wall all damaged. 2. USB Storage The USB memory did not record any information.

This car is three months old. Driving near my home on a four-lane divided road with 55MPH speed limit. While having either cruise or auto-steer enabled and using cruise control only, experiencing ongoing instances—during every drive—of unexpected and unexplained hard, sudden braking, reducing vehicle speed dramatically (multiples of 10MPH in less than five seconds). Each time, there has been very light traffic, and there is nothing I can see on the road that could explain the reason for the braking, hence the unexpected nature. The problem could easily cause a rear-end collision soon if another car is following closely, and I’m not able to correct and accelerate fast enough. Vehicle is very clean all around, including camera locations, and the weather is perfectly sunny and temperate each day. I do not recall this event happening while driving at night in my semi-rural area. I have not yet reported the problem to Tesla, so they have not inspected or attempted service on the vehicle.

I was trying to reverse the car from my Garage. I turned on the Engine and put the vehicle in Reverse Gear. The vehicle just zoomed out of the driveway leaving me without the ability to control it and hit a tree on a neighbor's house and stopped. Then I tried to bring the Car into the Garage by engaging the Drive Gear. Again, the vehicle zoomed into the Garage, hit a few objects in the garage and stopped. At that point I just turned off power and walked out. I took pictures of the damaged parts. At that time, I only noticed damage to the Rear on the Driver Side and the front on the Driver Side. When a tow-truck came a couple of days later, I noticed damage on the Front on the Passenger side also. When the incident happened , the street was empty and luckily no one (including me) was hurt n

Vehicle Information: • Make: Tesla • Model: Model Y • Year: 2025 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) 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.

2025 Tesla model Y cameras and sensors all stopped working within 700 miles driven from brand new. Affected systems included all cameras, including backup camera, as well as GPS navigation, with the GPS system believing the vehicle to be static at a Tesla facility in California. This not only prevented the self-driving and navigation from functioning, it caused numerous safety features to be disabled including (mandatory) backup cameras, collision-avoidance system, lane-departure warning system, cross-traffic alert system, rear collision avoidance system, and automatic safety braking. Upon reporting to Tesla, was told a "new component" was required, which later was told was a new computer. The manufacturer initially set a date 2 weeks in the future for a repair; then they pushed it a month; then tried to push it another month before I pushed back. This resulted in it being taken in earlier than the repair date. The vehicle is still awaiting repair. There were no warnings of this failure, it simply all happened at once. Upon confronting Tesla service with this being a known issue [XXX] ) and requesting a loaner for the meantime, they eventually found one, but only after great protestation and pushback, with eventual threats of legal action leading to a more personal touch. This is clearly a known issue which they are downplaying. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I took delivery of the Tesla Model Y yesterday (12/24/2024). The car has 73 miles on it as of now. First, the rear view camera stops working this morning (12/25/2024) and parking assistant is not available. Then the autopilot won't turn on and the car shows an alert that "power limited". After I arrived home from a supercharger (the car is charged to 80% as of now) around 1pm, the screen turns brick, and it will not turn on again after rebooting. It can drive, but the power feels weak. I called Tesla roadside service. The car has been towed to the Fresno service center.

Automatic Emergency braking stopped working. Parking assist stopped working. Back window is dismal. You can't see anything behind through the window. All cameras stopped working and it poses a safety hazard.

All cameras and related functions stopped working, including back up camera. GPS is not working. Tesla pushed back my service appointment until 1/21/25. Safety is an issue now due to blindspots and they will not give me a loaner car. Tesla informed me the computer needs to be replaced. They reported this is wide spread and Tesla is not sure why it happened. I was informed that even though my new appointment is 1/21 it is likely that it would be pushed back further. I have only had this car for 5 weeks. No warning lights came on prior to this happening.

Computer system failure causing all cameras to fail, mirrors to stay darkened even in daylight, navigation system not updating, collision and lane departure feature failure. Issues were reported to Tesla and an AP 4 computer replacement were scheduled, however service has been delayed for several weeks ( now 9 Jan 2025). The car does not feel sufficiently safe to drive with the impaired mirror visibility couples with the lack of any cameras or safety features working.

The automatic pilot computer (AP4) failed on my 2025 Tesla Model Y after approximately 400 miles. This controls a lot of the vehicle's auto pilot features but it also controls a lot of its safety features, such as the back-up camera, forward collision warning and blind spot warning. As of 19 December, the Tesla Service Center has had my vehicle for 14 days with no fix for the foreseeable future.

What component or system failed or malfunctioned, and is it available for inspection upon request? There were multiple component and system failures that were experienced. My vehicles autopilot and full self driving took over causing my vehicle to crash head on into a tree. How was your safety or the safety of others put at risk? My safety and others were at risk because I had no control over my vehicle. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. The car was taken into custody of the insurance company. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No.

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 December 7, 2024. I scheduled the soonest appointment available for December 24, 2024 however Tesla contacted me and moved my appointment because they stated that the part was unavailable at this time and should be delivered by January 24, 2025. Not offering me a rental or anything on my brand new 2025 Tesla. It has just under 1,000 miles on it and have the car since November 8, 2024. 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. This has increased the safety risk of my vehicle tremendously. Tesla has not seemed to publicly acknowledge the issue yet either.

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.

Safety is the first think that I believe

We were Driving East on I-40 at mile marker 245 Friday Nov 29 2024 around 8:50am in the right lane. We were passed by a gray Ford F-150 on the left. We had the "Traffic Aware Cruise Control" enabled. Our Tesla braked hard when the F-150 was directly beside us. The Ford was not in our lane at any point, and never changed lanes. Luckily a car behind us was not following too closely or an accident could have happened.
