On March 23, 2026, my vehicle experienced a sudden and simultaneous failure of multiple critical safety systems without any prior warning. The alerts displayed included: automatic emergency braking unavailable, traction control disabled, stability control disabled, and additional driver-assistance features becoming unavailable. This incident created a serious safety hazard, as the loss of these systems significantly reduces vehicle stability and braking assistance, increasing the risk of loss of control, especially at highway speeds or in adverse weather conditions. In addition, the front-facing camera exhibits fogging and reduced visibility during cloudy and rainy conditions, which further impacts the reliability of safety and driver-assistance systems. Based on my research, similar issues have been reported by other Tesla owners, suggesting this may not be an isolated incident but a potential pattern defect. I am concerned about the safety of operating this vehicle and request that this matter be investigated for potential defects affecting critical safety systems.
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.
It was snowing and I was driving slow. About 8:40am, Feb 6th, 2026, I got a "one pedal driving disabled" alert just for a moment, then tried to stop before an intersection because a signal was turning to red. However, break didn't work and I had to enter the intersection under a red signal. Fortunately, there was no car in front of me, also a car coming from the side didn't notice signal changed. No accident, but very very scary. On Dec 6th, I also got an alert "one pedal driving disabled" and even after I released an accelerator pedal, speed didn't slow down. I reached Tesla on Feb 6th, but the service scheduled 4 weeks later. It's not safe to drive at all, thus, I will try to have them to check my vehicle ASAP.
Any time you drive my vehicle there’s either violent shaking in the brake pedal, steering wheel, tires. When you try to brake it stutters. Using fsd it failed to stop instead almost hit a pedestrian on scooter and reported the time and date to Tesla. It stuttered and thank god I was able to jam in brakes. After 9 service visit the admitted they missed something and wheel alignment was off and tires were cupped. Along with a bracket for suspension. Which has not solved issues. It scary driving this vehicle especially as a single father who has to make long trips in the weekend for hockey.
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.
1. There is a constant thunking noise coming from the front suspension when traveling on slightly bumpy roads at low speeds. 2. Both front seats squeak and squeal as if they are loose and not bolted in correctly. 3. Front brakes screach and squeal when coming to a stop in cold or wet weather, escpecially pronounced during cold weather. (this is an active service bulletin in all vehicles made in their berlin factory but is happening in u. S. Built vehicles as well.
My 2026 Tesla Model Y with under 3,000 miles experienced a sudden and total loss of power steering while driving. The car became extremely difficult to control. Tesla towed it to their service center, where they claimed it was a software-related issue that could not be replicated. The service center released the car back to me but refused to provide written assurance that the vehicle is safe to drive, stating only that it is “cleared for release. ” I’m concerned this issue could reoccur, creating a risk of loss of control and injury. The lack of transparency and refusal to confirm the vehicle’s safety in writing raises serious safety concerns about potential defects in the steering or software systems.
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) . The the damage was highly unusual — although I was driving slowly, approximately 10 to 15 miles per hour on my street, the front wheel became completely detached from the suspension, the suspension itself was severely damaged, however, the rest of the car’s body sustained with minimal impact. I had hard time to find Tesla service to help me, so I contacted allstate and they had a towing company to transport the vehicle to gwatney collision center, the only Tesla-certified body shop in our area.
Since I purchased my 2026 Tesla Model Y rwd, the vehicle has had a persistent mechanical noise and vibration issue coming from the front suspension and brake area. This issue has been ongoing since the first weeks of ownership and has not been repaired or properly diagnosed after multiple service visits. Details -component/system failed: front suspension/brake assembly (unknown exact component; may involve control arms, bushings, or brake rotors). -availability for inspection: yes, the vehicle and recorded videos are available for inspection upon request. -safety risk: the vehicle produces loud clunking or popping noises when driving between 10–20 mph or when turning and braking. It feels unstable and unsafe at times, especially on wet roads. This raises concern about potential front-end component failure while driving. -reproduction and confirmation: the issue has been reproduced and confirmed multiple times by Tesla service in vancouver, wa and portland, or. Tesla’s internal system shows that the issue was escalated for “in-car investigation by engineering,” but no permanent repair was completed. -inspection history: Tesla technicians and engineers have inspected the vehicle several times. I also recorded multiple videos with cameras mounted inside the fender to document the sound and provide visual proof of the problem. -warning lamps or messages: no warning lights appear. The issue is purely mechanical but noticeable during low-speed operation. The first symptoms appeared within the first month of delivery. -manufacturer contact: Tesla service centers in vancouver and portland are aware of the issue and have escalated it, but no resolution has been provided. This problem has continued for months despite repeated service visits. The vehicle was identified as needing further “factory-level investigation,” but I was told the local service centers cannot fix it. I believe the issue may be a manufacturing or design defect affecting suspension safety. My life is risk.
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. The vehicle was not repaired. The manufacturer was notified of the failure and offered no assistance. The approximate failure mileage was 4,900.
While driving along a few roads using traffic aware cruise control (tacc) or autopilot (ap), the car will suddenly brake for no reason at all. Speeds reduced from 75 to 50 in 2 seconds. Had there been a car close behind me, we may have collided. I am able to reproduce this on several other roads as well. I have not yet reported this to the manufacturer, but a review of internet forums shows this to be a relatively common occurrence among owners. They refer to this as phantom braking.
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.
My 2026 Model Y won't stop on the road when I released the gas paddle and even I felt it speeded up a little bit at 35 miles. It put me, my [xxx] daughter and other's safety at risk. I hit on the brake and feel need to hit harder abnormally to slow the car not even mention to stop the car. It took me long way to stop the car. At once I stopped the car, it tried to speed up and I hit the paddle again. Right after, then it tried to rocking back and forth and vibrated finally stopped. I tried serval time to repeat the issue it still exits. And I called Tesla customer service. They haven't look at it yet. But I in the service mode here is the some components are malfunctioned. 1. Rgenerative braking backfill, braking pedal torque is unavailable. 2. Traction control setting is unavailable. 3. Di_brake torque is invalid. Di is drive interface. 4. Hold stopping mode is unavailable. There is no any warning showed in the console before and after the issue happened. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
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.
