On [xxx], the owner of a 2026 Tesla Model 3, left the garage of her house in the Tesla, and engaged the self-driving as the driver has done dozens of time in the past. The car proceeded down the driveway, as it has always done in the past. However, in an instant, before the driver had time to react, the car went straight where the driveway curved, and the car hit a tree. The video from the Tesla cameras was saved and confirms that the car was in self driving mode, there was no driver intervention causing the accident, and the driver did not have time to react and prevent the accident. This accident was due to a failure of the Tesla self-driving. The encrypted dashcam video was copied from the usb drive named [xxx], from the folder [xxx], and then accessed by logging into [xxx] and dragging and dropping the video file into the dashcam app. That was saved to our pc as [xxx}. Since the saved video did not show the telemetry data, the video was loaded into [xxx] and saved with the telemetry information visible. Another video was saved capturing the whole exportdash. Cam interface. That has bars showing where the car was actively steering, braking, or applying acceleration (“gas pedal”). This shows that the car was actively steering a second before the collision, but then stopped. There was no time for the driver to react to the car's failure to properly steer. The video showing the car in self-driving mode and failing to navigate a turn on the driveway can be accessed at this youtube link: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.

On sept 22 2026at approximately 10:26 am, my Tesla vehicle was involved in a low-speed, 5 -10 mph rear-end collision while the full self-driving (fsd) supervised automation system was engaged. The vehicle failed to initiate a timely braking sequence for a lead vehicle, resulting in an impact. There was a sudden accleration right before the hit along with a sudden braking. Critical safety failures & discrepancies: 1. Unwarned system degradation: following the incident, Tesla service technicians reviewed my vehicle diagnostics and explicitly stated that internal logs flagged the fsd system performance as degraded or "suspect" since the beginning of September 2026. However, prior to the crash, the vehicle provided zero driver-facing warning messages, dashboard alerts, or mobile application notifications indicating that the automated safety systems were compromised or operating with a defect. 2. Telemetry log contradiction: Tesla's initial internal review claims that the vehicle's telemetry indicates an accelerator pedal override by the driver. I explicitly state that my foot was not on the accelerator pedal and no such override was physically made. There is an active sensor tracking or system logging discrepancy regarding driver inputs during this fsd failure. Evidence maintained: I have preserved the complete, 4-angle synchronized Teslacam dashcam footage of the incident on my computer as visual proof of the vehicle's un-accelerated 5 mph forward creep. Furthermore, I have submitted an official data privacy request to Tesla to force the extraction of the raw, unredacted vehicle telemetry logs (di_accelpedalpos) to legally dispute their pedal position claims. I am filing this report to assist NHTSA's active investigations into Tesla autopilot/fsd traffic safety violations, specifically concerning automated braking failures and inaccurate driver-override telemetry classification.
I had fsd (full self driving) (supervised) enabled. The navigation map and turn instructions (which appear on the right side of the touchscreen) indicated that my car was to make a left turn at the upcoming intersection. After a full stop (at the stop sign), my car crept out into the intersection, preparing to make an unprotected left turn (upl) onto a major street (2 lanes of traffic in each direction). My car stopped (creeping out) when fsd “realized” that it was not yet safe to make the turn. My car, however had crept out far enough so that other vehicles coming from my left (in the right lane) had to swerve left to avoid hitting my car. There was another car behind my car so I could not “manually” back up (taking over from fsd) to remove the front of my car from the path of vehicles coming from my left. (if just one of the drivers of those vehicles coming from my left had been distracted, a likely collision with the front of my car could have occurred!) eventually, there was a sufficient gap that I could (manually) make a right turn instead. Since this incident, I have had to preview the navigation map for every trip (before enabling fsd) and be prepared to route around any upls. After driving this car over 6500 miles (98 % on fsd), I have found fsd to be very safe overall! my only notable “risk of collision” event was the above-described upl attempt! I have contacted Tesla customer service (via phone calls and online) on several occasions to report this hazard, but nothing has been done; (although on a live phone call, the representative acknowledged that others had also voiced my concern!) during a chat with Tesla’s “grok” chatbot, grok stated that a ‘prefer protected turns’ option would be a low complexity addition that could coexist with continued upl improvement”. Given this information, I think Tesla is being negligent by not adding the “prefer protected turns” option to the vehicle user interface.
“the affected system was Tesla full self-driving (fsd) (supervised). Fsd correctly selected the northbound left-turn lane but, while executing the left turn to westbound pecan street, intermittently directed the vehicle into the eastbound lanes carrying opposing traffic. ”.
On August 26, 2026, at approximately 8:56 am, I entered a public parking garage in washington, DC. Full self-driving (supervised) was engaged and controlling the vehicle during a reversing maneuver. I remained attentive to the vehicle's surroundings, including pedestrians and surrounding traffic. While reversing under fsd (supervised), the vehicle's right rear corner collided with the corner of a stationary structural pillar in the parking garage. I did not command the vehicle to steer into the pillar. Upon becoming aware of the impact, I immediately applied the brake. There were no injuries. The collision resulted in damage to the right rear area of the vehicle. After the incident, I photographed and recorded the scene and vehicle damage and saved the available Tesla dashcam footage. I also requested the vehicle data from Tesla. I am reporting this incident because the vehicle collided with a stationary structure while fsd (supervised) was engaged and controlling the reversing maneuver. I do not know the specific technical cause of the incident. The vehicle and available recorded data can be made available for inspection upon request.
Tesla Model 3 full self-driving (supervised) feature I was using self-driving mode in my Tesla Model 3 while traveling on [xxx]. The vehicle suddenly turned right without warning, struck a mailbox, broke the right-side mirror, and came to a complete stop. There were no vehicles in front of or behind my car at the time of the incident. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
The horn system on the new Tesla are not effective. Other drivers cannot hear the unit is facing the ground, and a high speed. Other drivers. Can I hear it specially when it’s raining. The use of the original point was effective and never had a problem on my previous last Tesla, or any other car for that matter. Please help before a serious. Ask her that happens.
After a recent Tesla software update, a mandatory full self-driving disengagement feedback window appears every time I disengage fsd while the vehicle is still moving. The feedback window covers a large portion of the display with a black overlay, noticeable enough something popped up. There is no setting to disable it, dismiss it immediately, or postpone the response until the vehicle is stopped. I am required to select a disengagement reason before I can access the controls and information behind the overlay. While this window is displayed, I cannot properly view or control functions such as music and other touchscreen features behind the area. This is especially dangerous because it appears immediately after I take manual control from fsd—a moment when my full attention should be on the road and the vehicle. The system effectively requires me to look away from the road and interact with the touchscreen before I can make another needed adjustment. This occurs every time I disengage fsd and is consistently reproducible. This behavior began after software version fsd v14. 3. 3. My vehicle is a 2026 Model 3. The problem occurred everytime while traveling at any speed. I believe this mandatory, non-dismissible overlay creates a serious driver-distraction hazard by obstructing the center display and requiring touchscreen interaction while the vehicle is in motion. Tesla should allow the feedback request to be dismissed, delayed until the vehicle is parked, or disabled entirely.
Complaint title: defective horn system on 2026 Tesla Model 3 - ineffective in rain or highway conditions description: the horn on my 2026 Tesla Model 3 highland is dangerously inadequate. It uses a single pedestrian warning speaker instead of a proper horn, which is easily overpowered by road noise, tire noise from large trucks, and especially rain. I cannot reliably alert other drivers, including 18-wheelers, when they are drifting into my lane or failing to yield. This creates a serious safety risk in wet conditions and highway driving. Traditional horns have been effective for decades — this design fails basic safety expectations. I am requesting immediate investigation and a fix.
We bought the new 2026 Tesla Model 3 and picked it up on 5/3/2026. The next date 5/4/2026, I was trying to drive it to work. I got in the car and used the Tesla’s full self-driving function and let it drive the car by itself. It started moving forward and tried to make a u turn. Since there was not enough space for it to make a u turn because there was a car parked on the sidewalk, so it stopped for a moment. But unfortunately, it continued to move forward and hit the car parked on the sidewalk. It supposedly backed up a little after the stop, but it didn’t detect the car parked on the sidewalk and still moved forward and hit the parked car. The Tesla's fsd is malfunctioning and caused my accident because there was such a big car in front and it didn't detect it and still hit it.
