2026 Tesla Model Y Brakes Problems

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'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. The brakes did not respond as they did mere seconds before and I hit a parked car. I understand teslas may throw codes left and right in service mode that may mean nothing, but I am worried about the brake booster code and wonder if maybe it caused the accident I was involved in. My friends told me they heard about tesla brake issues and that I should look into it and when I went to go check the codes hours later there they were.

The contact owns a 2026 Tesla Model Y. The contact stated that while driving at approximately 10 MPH into a parking spot, the contact depressed the brake pedal, but the vehicle failed to stop. 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 vehicle was able to be driven away from the crash site. The vehicle was taken to the dealer, who test-drove the vehicle. The contact was informed that the vehicle was not equipped with a manual parking brake; however, the brakes were functioning normally according to the computer, and to wait for corporate's report before taking the vehicle to a collision center for front-end repairs. The vehicle was not repaired. The manufacturer was made aware of the failure and opened an investigation. The contact was informed that the vehicle was safe to drive. The failure mileage was approximately 6,000.

There is a SERIOUS safety-related FSD (full self driving) fundamental design flaw with stop sign behavior. On previous versions AND on the latest and best version of FSD (currently that is v14.2.1.25) when FSD approaches a stop sign AND there is no white painted stopping line, FSD will make its full initial stop (also called the zero-speed stop) directly at or behind the stop sign instead of making the initial full stop beyond the stop sign at a location where the driver can see cross traffic. Sometimes the FSD initial full stop is 20, 30, 40, even 50+ feet back away from the edge of the road. At these distances from the edge of the road, most of the time, there is NO VISUAL of cross traffic left and right. The FSD stop then turns into the FSD "creep" where FSD, after stopping 30 feet back WILL THEN commit to the turn from 30 feet back giving drivers little to no time to see cross traffic. If I am the supervisor of FSD who is liable for my safety and my vehicle's safety, I need to be able to see cross traffic before my car (with FSD engaged) decides to commit to the turn, but FSD DOES NOT CARE IF THE DRIVER CAN SEE. The "creep" is perhaps the least human-like manuever that FSD performs. From the stopped location directly at the stop sign, they creep may inch up and stop again, it may inch up a COUPLE TIMES and stop again, it may pull up to the edge of the road and stop again, OR it may just pull out into oncoming traffic in one swift motion. Bc of this behavior, FSD has almost got rear ended countless times at stop signs. Also, cross traffic see's the creep and thinks i'm about to pull out in front of them Drivers go beyond the stop sign to a location where they can see to make their one and only full stop. To avoid this issue, FSD needs to do this too (i.e. make initial full stop at the edge of the road) This is legal in mostly every state (I live in PA) Tesla has not provided a single response to these reports and nothing seems to be getting done about it.

On several occasions, my Tesla Model Y has braked for no reason while using Traffic Aware Cruise Control as well as when using Autopilot. I can re-create this situation on the same parts of the highway. The sudden, uncommanded stopping creates a hazardous situation with the cars being me as I may get rear ended. At this point, I do not feel safe using Autopilot or TACC. I submitted a ticket to Tesla but they declined to work on it.

We just took delivery of our 2026 Tesla Model Y Juniper yesterday. Today, my wife was driving to work at around 40 mph when the car suddenly performed a hard brake (phantom braking), coming to a complete stop for no apparent reason. The driver behind her nearly rear-ended her. Importantly, she was not using Autopilot or Full Self-Driving at the time of the incident.

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.
