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.
Incident involving my 2026 Tesla Model 3 equipped with hw4 hardware and the latest fsd (supervised) software. During a garage reverse maneuver performed under fsd supervision, the vehicle had sufficient time to assess the surrounding environment before initiating the maneuver. There were no pedestrians or moving obstacles nearby. An adjacent parked vehicle was present next to the intended reversing path. During the maneuver, the vehicle made initial contact with the adjacent vehicle. At no point did the vehicle provide any collision warning, alert, or indication that a collision had occurred. After the initial contact, the vehicle continued moving and a second impact occurred shortly afterward, resulting in additional damage. Immediately after the second impact, the driver intervened and took control of the vehicle to stop the maneuver, before further damage is caused. My main concerns are: 1. Why did fsd fail to identify the adjacent vehicle before the maneuver? 2. Why was no collision warning provided before or after the initial contact? 3. Why did the vehicle continue the reversing maneuver after the first impact instead of stopping till driver intervention? 4. What if is pediatrician who qualify ada, children, elder was in the position of the adjacent vehicle, this failed sensing would cause imparable result. I would appreciate a technical review of this event and a detailed explanation of Tesla’s findings.
The vehicle's full self-driving (fsd) system was actively controlling the vehicle while executing a reverse maneuver into a residential garage — a routine the system had successfully performed on multiple prior occasions. During this session, the fsd system misjudged the maneuver and the vehicle struck the wall of the garage, causing damage. The failed component is the fsd software/sensor system. The vehicle is available for inspection upon request. Safety was put at risk because the system was in full control of vehicle movement in a confined space. The unexpected behavior did not provide sufficient time for the supervising driver to intervene before impact. No warning lamps or messages appeared prior to the failure. The system gave no indication it would behave differently from previous successful executions of the same maneuver. The incident has not yet been confirmed by a dealer or inspected by the manufacturer, though a vehicle incident data report has been requested from Tesla.
On February 5, 2026, at 12:21 pm pst, my 2026 Tesla Model 3 (hardware 4) collided with a 5-inch wooden pillar while using the autopark feature. The system failed to provide any audio chimes or visual warnings prior to the impact. I officially requested the driving logs from Tesla to investigate the cause of this failure, but Tesla refused to provide any logs or data. Furthermore, Tesla service center technicians insisted there were no hardware defects, effectively confirming that the collision was caused by a software/algorithmic failure of the Tesla vision system to detect a stationary vertical object. Despite Tesla’s claim that the vehicle is "operating as designed," the system's inability to recognize common infrastructure and its failure to warn the driver constitutes a severe safety risk. This defect must be investigated to ensure the safety of the hardware 4 autonomous platform, as the lack of proximity alerts could lead to far more serious accidents involving pedestrians or other obstacles.
