What owners report

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. …

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 was using the vehicle's Autopark feature to parallel park on a public street in a normal/spacious parking spot. I selected the parking spot on the center screen and started Autopark. During the maneuver, the vehicle reversed into the parked car behind me and caused a dent (low-speed crash). I was supervising the maneuver and did not press the accelerator or brake before impact. After the incident, I reviewed dashcam footage and vehicle telemetry. The rear vehicle was clearly visible in the rear camera view. Telemetry shows the vehicle had already shifted to Drive before impact, but it continued moving backward for about 1 second and then contacted the parked car behind. Telemetry also shows accelerator pedal position was 0 and brake was not applied during the impact sequence. This appears to be an automated parking/close-range obstacle stopping failure or delayed stopping response. …

On March 14, 2026, at 20:54:21 UTC, while the Autopilot system was engaged, the vehicle malfunctioned by initiating a sudden, unprompted right-hand steering command within 0.3 seconds, resulting in a collision with another vehicle traveling in the adjacent right lane. Telemetry data from the event confirms the system failed to maintain the lane despite the Primary Steering Torque Sensor measuring 0.00 Nm, proving no driver input caused the maneuver. This unintended steering event at cruising speed created an immediate safety risk to myself and the occupants of the other vehicle. To date, the manufacturer (Tesla) has declined to perform a technical or remote diagnostic review, redirecting the case to a collision center instead. …

I purchased a 2024 Tesla Model 3 a little over a year ago. Recently, and after an update, myself, and other drivers in my life, noticed the self-driving feature was malfunctioning - to the point I used the audio reporting feature to report this problem twice to Tesla. The car would veer off the road when flasing lights appeared and would jerk suddenly for no reason when it thought there was a obstruction in the road (sticks, plastic bags, etc.). Last month this malfunction has caused an accident, and my car has been totaled, my insurance will not cover it, and I have been advised by two separate attorneys to sue. This has been litigated in court with lawsuits against Tesla (See Benavides v. Tesla; see also IN RE: TESLA ADVANCED DRIVER ASSISTANCE SYSTEMS LITIGATION). …

On October 17, 2025, while Full Self-Driving (Supervised) was engaged, the vehicle made an abrupt, uncommanded steering input to the right, causing a collision with a tunnel wall. This crash appears to be the result of a critical vehicle hardware failure. In the 24 hours prior to the crash, the vehicle logged multiple critical steering errors, including EPAS3P_a086_dasMia, which indicates the Electric Power Assisted Steering system was "Missing in Action" and not communicating. Furthermore, the vehicle has logged daily, recurring hardware faults for the Steering Column Control Module (SCCM_a016_hardwareError) since it was purchased. The uncommanded steering action created an extremely dangerous safety condition resulting in a collision. All stability and traction control faults appeared at the exact moment of impact, not before, indicating the steering system failure was the root cause. …

The contact owns a 2023 Tesla Model 3. The contact stated that upon starting the vehicle and shifting to drive(D), the front trunk opened inadvertently, blocking the visibility of the roadway. The contact stated that the failure had recurred several times upon shifting to drive(D), which required the contact to exit the vehicle and manually close the trunk. The vehicle was taken to a Tesla service center and to Tesla Service Sunnyvale(680 E El Camino Real, Sunnyvale, CA 94087), where unknown repairs were performed several times; however, the failure persisted. Additionally, the contact stated that while attempting to reverse out of the garage, the contact was unaware that the garage door was closed, and the vehicle hit the garage door. …

The contact owns a 2023 Tesla Model 3. The contact stated that while entering a parking lot, the brake pedal failed to respond, the driver was unable to control the steering wheel and crashed into a Ford vehicle and a tree. The air bags deployed, and the vehicle stopped shortly after. The forward collision emergency braking system failed to engage. There were no warning lights illuminated. The vehicle was towed to a tow lot. A police report was filed. There was no reported fire. The contact sustained injuries to the neck and shoulder and had bruises. Medical attention was provided. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 12,166.
