FSD Safety Incident – Collision While Exiting Parking Space My Tesla Model Y was operating in Full Self-Driving mode while exiting a parking space. Instead of proceeding straight out of the parking space, the vehicle accelerated while turning toward a basketball pole and collided with it. There was a clear, unobstructed path to exit straight ahead. The vehicle’s unexpected acceleration and turning maneuver happened so quickly that I did not have time to intervene. My hands were positioned next to the steering wheel, ready to take control. I believe this was an FSD driving error and am requesting a formal investigation.

Severe vehicle electrical network short circuit and central computing safety failure. Following a factory warranty replacement of the front windshield bi-cam assembly, the vehicle's internal diagnostics flagged continuous Redundant Control Unit (RCU) data link communication errors and an active network voltage mismatch (VCFRONT_a265_ESPVoltageMismatch). While actively operating the vehicle at speed on a live roadway, the main infotainment screen and safety computer completely locked up, went black, and froze on the Tesla logo. I suffered a total in-motion loss of my speedometer, primary safety displays, and driver operational interface while moving on a live street. Video proof captured on the road confirms that the vehicle's high-speed Camera Serial Interface (APP_w352_csiDevice1Down) is actively shorting out mid-drive, overloading the primary CAN bus communication network and crashing the safety computer while the vehicle is in motion. This vehicle represents an immediate driving hazard.

Subject: Suspected Sudden Unintended Acceleration While Reversing — Tesla Collision on October 25, 2026 On October 25, 2026, at approximately 11:00 AM Pacific Time, I experienced an unexpected acceleration incident while reversing my Tesla on my property. I was reversing slowly when the vehicle lightly contacted another car that I own. Immediately afterward, the Tesla unexpectedly accelerated backward at a much higher speed and struck my garage with considerable force. The garage impact brought the Tesla to a complete stop. The vehicle subsequently moved forward and stopped. Fortunately, nobody was in the vehicle's path. However, the incident created a serious risk of injury, particularly if children or pedestrians had been nearby. I visited a Tesla Service Center after the incident. I was instructed to obtain a Tesla privacy data report, but I have not yet received a technical explanation. My preliminary review of Tesla's vehicle data indicates that the recorded accelerator signal increased from approximately 4.4% to 100%, reverse speed reached approximately 12.4 mph, and a crash-related event and braking activity were registered. I do not remember my exact foot position during the incident. I cannot determine whether the acceleration was caused by physical pedal input, an electronic or mechanical fault, or another factor. I am requesting that the federal safety agency review this incident as a potential vehicle safety concern. My primary objective is to understand what happened and help prevent similar incidents from causing serious injury or death. I can provide the original Tesla privacy report, photographs, and additional details upon request.

While using Full Self-Driving (Supervised), the vehicle drove appropriately on [XXX] through the school zone, stopped at the traffic light, and made a right turn onto [XXX]. Immediately after the turn the vehicle accelerated rapidly, changed into the left/inside lane, and reached 46 mph in the active 20 mph school zone. I was pulled over; the officer’s notes state actual speed 46 mph, active 20 mph school zone, inside lane pulling away from all traffic. The acceleration happened extremely quickly.

While driving on Colorado state highways with Traffic-Aware Cruise Control (and/or Autopilot) engaged, the vehicle repeatedly and unexpectedly decelerates rapidly from highway speeds of 75–80 mph down to approximately 45 mph. This occurs with no vehicles, obstacles, or other hazards visible ahead that would justify the slowdown. The deceleration is abrupt and feels aggressive. It has happened on multiple occasions during normal highway driving. I am forced to immediately override the system by pressing the accelerator to regain speed and avoid creating a hazard for traffic behind me. The issue occurs even in clear conditions with good visibility. This sudden braking creates a significant safety risk of being rear-ended by other drivers who are not expecting a vehicle to drop 30+ mph without warning. I have experienced this repeatedly and am concerned it is a safety defect with the vehicle’s cruise control / driver-assistance system. The problem occurs specifically when cruise control is active and does not appear to happen in the same way when I am fully controlling the throttle manually.

On XXX at approximately 1:18 PM Pacific Time in [XXX], my Tesla Model Y collided with a stationary metal post/barrier while operating under Full Self-Driving (Supervised). FSD was controlling the vehicle during a low-speed maneuver. The vehicle moved forward and struck the stationary obstacle. I did not intentionally press the accelerator, apply the brakes, or override the steering before impact. I applied the brakes only AFTER the collision. This was not a collision caused by my manually steering or accelerating the vehicle into the obstacle. I have preserved the original Tesla-recorded accident video, which displays the blue "Self-Driving" indicator during the relevant maneuver. Tesla's official vehicle data also records: 13:17:50.255 - ACTIVE_FSD 13:18:17.661 - Significant acceleration anomaly, approximately -7.29 m/s², consistent with a possible impact 13:18:18.268 - DRIVER_APPLYING_BRAKES 13:18:18.285 - FSD state UNAVAILABLE The suspected impact event occurred approximately 0.607 seconds before the recorded manual braking event. This supports my account that I braked in response to the collision, not before it. I am concerned that FSD failed to avoid a stationary obstacle while controlling the vehicle. I request that the federal safety agency investigate FSD obstacle detection, path planning, steering, propulsion and braking behavior, and whether adequate collision warnings were provided. I request preservation and examination of Tesla's complete FSD logs and an assessment of whether the automated system contributed to this collision. I dispute any assumption that this incident was caused solely by manual driver operation. I have the original video, Tesla CSV data and damage photographs available as evidence.

The speed recognition of Tesla Full Self Drive is unsafe in its present form. The speed recognition is very inaccurate. While driving on an interstate highway where the speed limit is 70MPH, it is recognizing a route sign with a much lower number as a speed limit sign and suddenly applying braking, causing me to nearly be rear ended on multiple occasions. Every time I pass this sign I have to either disengage full self drive, or I have to override it to keep from being rear ended. The same thing happens on another highway, where the exit ramp has construction going on. When you are on the main road, it recognizes the exit ramp construction speed limit and tries to reduce you from 65 to 35. This problem has been reported to the manufacturer with no response other than "it is being forwarded on to the appropriate team for review"

While using Tesla Full Self-Driving (Supervised), my vehicle approached an intersection and came to a complete stop at a red traffic light. The vehicle remained fully stopped while the traffic signal was still red. Without any accelerator input from me, the vehicle unexpectedly began moving forward toward the intersection while the traffic light was still red. I did not press or touch the accelerator at any point during this event. As soon as I realized that the vehicle was moving forward against the red light, I immediately applied the brake to stop the vehicle and then immediately reversed to move back to a safe position. My intervention was necessary to prevent the vehicle from entering the intersection and potentially colliding with cross traffic. There was no collision and no physical injury. However, the unexpected movement created an immediate and serious risk of a collision. My pregnant wife was in the passenger seat at the time of the incident. Full Self-Driving (Supervised) was engaged throughout the event. I have preserved the original Tesla Dashcam footage documenting the incident, including the red traffic signal, the vehicle coming to a complete stop, the unexpected forward movement while the signal remained red, and my immediate braking and subsequent reversal. I am reporting this incident because the vehicle unexpectedly proceeded toward an intersection against a red traffic signal while Full Self-Driving (Supervised) was engaged, requiring immediate driver intervention to avoid a potential collision.
