The vehicle drove over a parking bump, struck a bench, and the automatic emergency braking system engaged, preventing the vehicle from hitting the wall. The air bags did not deploy. The contact stated that she had back pains, but was unsure whether they were related to the failure. There was no medical attention received. A police report was filed.

The contact owned a 2026 Tesla Model Y. The contact stated that while depressing the brake pedal to attempt to stop at a stop sign, the vehicle failed to respond as intended. The contact mentioned that when attempting to make a left turn, the steering wheel seized and became difficult to maneuver, and the vehicle crashed into a curb and merged into a landscaping facility. The contact was able to shift the vehicle into neutral, then reverse. The vehicle began to work as intended, and he looked out of his rearview mirror. He could see smoke coming from the rear passenger side, and he heard an abnormal noise coming from the rear passenger tire. No warning lights illuminated. A dealer was contacted. The vehicle was towed to a dealer to be diagnosed; however, the diagnosis was unknown. The contact mentioned the dealer, and insurance deemed the vehicle a total loss. …

On November 4, 2025, I believe my New Tesla (only 2 month old) had just updated to a new software version. That morning, when I tried to start the car to drive to Walgreens Pharmacy, the vehicle did not start - the screen was locked. I pressed the brake pedal several times, but there was no response. Then I pressed the accelerator and the brake again, and the car finally started. I believe i turned on the Full Self-Driving (FSD) mode as usual. The car backed out of my garage and moved only about ten houses down our street when I suddenly felt it was out of control, and within seconds, it hit a stationary vehicle on our street. I did not hear Forward Collision Warning or feel the Automatic Braking system engage. The tesla report told me that the collision warning failure and the Safety systems are affected, and the passage side (front right) tire shows 0 psi) . …

I've noticed periodically when the car is braking at start stop traffic in autopilot mode, the brake is very jerky and I can actually hear the pedal jerking and engaging. I wrote it off at the time in my head as normal operation of the car. I have brake pressure offset codes and brake booster mia codes. Sometimes I've noticed when I brake, randomly the pedal is super stiff and it feels like the car is driving on ice, as if the brakes aren't working or slowing me down at all, but I thought nothing of it at the time. Today on the 14th, I got into an accident at a relatively slow speed that in any other scenario I should have been able to stop. Yet I hit a parked car because as I was braking, I felt the pedal go very very stiff and unresponsive, and I carried the same speed as when I started braking right until impact, it seems as if I didn't slow down one bit. …

On August 15, 2026, at approximately 5:00 PM, the vehicle was being driven with Full Self-Driving (Supervised) engaged during light rain. As the vehicle approached traffic ahead, it did not slow or brake as expected. The driver recognized that the vehicle was not slowing and attempted to intervene manually by pressing the brake pedal multiple times. The driver reports that despite these attempts, the vehicle did not slow or respond to the brake pedal as expected, and a collision occurred. There were no known warning lamps or warning messages indicating a braking-system problem prior to the incident. The vehicle has not yet been inspected to determine the cause of the reported braking behavior. …

The contact owns a 2026 Tesla Model Y. The contact stated while driving using the ADS feature, the vehicle failed to slow down while making a right turn. The contact stated that when the vehicle came to the turn sign, the vehicle failed to yield and continued making the right turn. The contact's vehicle crashed into the rear of the vehicle in front of the contact's vehicle. The contact had to depress the brake pedal to stop the vehicle. No Police Report was filed. No injuries were sustained. The contact later received a warning that the vehicle's cameras needed cleaning. The technician came to the contact's residence and cleaned the cameras. The contact was advised to contact the NHTSA Hotline and report the failure. The manufacturer was made aware of the failure. The failure mileage was unknown.

I was driving my 2026 Tesla Model Y when another vehicle pulled out from a driveway and struck the front/side of my car. The Tesla failed to initiate Automatic Emergency Braking (AEB) and no airbags deployed. This raises serious concerns about the functionality of Tesla's safety systems in real-world scenarios. The vehicle has not been modified in any way and was in standard driving mode. I have contacted Tesla Support requesting a diagnostic and explanation, but I believe this incident should also be reviewed as a potential safety defect.

Our 2026 Tesla Model Y could not stop at a traffic light and rear ended the vehicle in front of it. Pumping the brake peddle had no effect. The incident did show up in the vehicles app. The front end was damaged (hood, drivers side fender and bumper). I contacted a Tesla representative and was instructed to make an appointment at a collision repair center to have the body work done prior to having the brake system diagnosed. I do not feel safe driving this vehicle at this time. I feel that Tesla should bear the cost for the collision repairs.

On April 11 2026, I was involved in a serious accident involving my 2026 Tesla Model Y. At the time of the incident, I was returning home from my daughter's event in downtown and had just entered my residential driveway. As I approached the driveway, I applied the brakes and slowed the vehicle. While momentarily stationary or near-stationary, I spoke to my wife, who was seated in the front passenger seat, advising her to secure the food she was holding due to the uneven surface of the driveway. Upon removing my foot from the brake pedal, the vehicle suddenly and unexpectedly accelerated without any input . The vehicle proceeded forward and collided with my garage door. Notably, no collision warning alerts were issued, and no automatic emergency braking system engaged prior to or during the impact. …

I purchased a new 2026 Tesla Model Y Standard and took delivery on approximately 30 May 2026. Within the first week of ownership, the vehicle displayed multiple safety-related warnings, including: * Steering Assist Reduced * Power Braking Assist Reduced * Automatic Emergency Braking Unavailable * Lane Departure Avoidance Features Unavailable * Automatic Vehicle Hold Disabled The warnings have occurred more than once. They initially disappeared and then returned on a later drive. Both incidents occurred while the vehicle was operating with Full Self-Driving (FSD) engaged. During the most recent occurrence, while parking at less than 3 mph, the vehicle's braking assistance appeared reduced and the brake pedal required significantly more effort than normal. As a result, I nearly struck a curb because the vehicle did not slow as expected. …
