2025 TESLA MODEL Y Service Brakes Problems

I am writing to formally report a serious safety incident involving a Tesla vehicle and to document multiple critical system failures that occurred during an accident, resulting in physical injuries to me. On the 12/24/2025, while operating Tesla under rainy conditions, I experienced a sudden and dangerous malfunction of the vehicle. During the event, the steering system became unresponsive and appeared to lock, preventing me from maintaining control of the vehicle. Simultaneously, the braking system failed to respond as expected despite my attempt to apply the brakes. These failures significantly impaired my ability to avoid or mitigate the collision. Most concerning, the vehicle’s airbag system did not deploy during the impact. Given the severity of the collision and the resulting injuries, the lack of airbag deployment represents a serious failure of a critical safety system designed to protect occupants in such events. As a direct result of this incident and the apparent malfunction of multiple safety systems, I sustained physical injuries that required medical evaluation and treatment. Beyond the physical harm, the incident caused significant emotional distress and raised serious concerns about the safety and reliability of the vehicle. I am submitting this complaint to formally document these safety failures and to request a thorough investigation into the performance of the steering, braking, and airbag systems involved in this incident. I believe this matter presents a significant safety concern not only for myself but also for other drivers and passengers who rely on these systems to function properly in emergency situations. Please confirm receipt of this complaint and advise me of the next steps in your investigation process. I am prepared to provide additional documentation, including medical records, photographs, vehicle data, and incident details, upon request. Thank you for your attention to this serious matter

The contact owned a 2025 Tesla Model Y. The contact stated that while the vehicle was parked in a school zone area, and while engaging the brake pedal, the vehicle unexpectedly lunged forward with no warning light illuminated. The contact stated that after lifting their foot from the brake pedal, they heard a hissing sound and the vehicle accelerated. The contact attempted to avoid a collision by making a left turn; however, the vehicle traveled into a bushy area and rolled down a hill. The contact sustained injuries, including head, neck, and back injuries, and received medical attention at a local emergency room. The contact stated that the air bags deployed during the incident. A police report was filed. The vehicle was towed and deemed a total loss. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 7,213.

ON 11/29/2025 AT 1635 HOURS, OUR TESLA MODEL Y - AWD WAS PARKED ON OUR DRIVEWAY WITH A LESS THAN 1% INCLINE AFTER IT WAS SNOW BLOWED, CLEARED OF SNOW. THE TESLA WAS PLUGGED IN TO ITS CHARGER. THE VEHICLE THEN UNEXPECTEDLY, UNCONTROLLED BEGAN MOVING FORWARD, STRIKING THE CAR IN FRONT OF IT SHORTLY AFTER I WALKED IN FRONT OF THESE TESLA. THIS INCIDENT COULD HAVE SERIOUSLY INJURED MYSELF OR ONE OF MY CHILDREN. TESLA SAID CAR IS OPERATING AS DESIGNED AND WAS DUE TO COLD TEMPS, SNOW AND SLIGHT GRADE OF DRIVEWAY. VIDEO IS AVAILABLE FROM SECURITY CAMERAS ON HOUSE WHICH CAN BE SUPPLIED UPON REQUEST AS YOU SYSTEM DOESN'T SUPPORT THE VIDEO UPLOAD.

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. MANUFACTURER RESPONSE: Service Visit Date: November 28, 2024 Diagnosis: Tesla Service Center acknowledged this as a

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.

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.

Tesla removed the creep/roll braking function (which mimicked an automatic transmission) from the Model Y 2024 forward. You now have to use the accelerator to control slow speed maneuvers like backing. It seems that it would be pretty easy to press the accelerator too much and have the car lurch forward or backwards. Seems like an accident waiting to happen. It would be safer to have your foot on the brake pedal and allow the car to creep backwards similar to an automatic transmission. Tesla should return the "creep" function as an option. This is what China is doing and the US should do the same.

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.

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.

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.
