Automatic Emergency Braking problems of the 2025 Tesla Model Y

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 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.

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.

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.

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.

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.

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.

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.
