Adaptive Cruise Control problems of the 2025 Tesla Model X

The full-self drive of my Tesla failed to follow the programmed navigation directions I set to take me home in one direction, but instead the vehicle took a completely different path on its own. When the vehicle was programmed to turn right towards my home, the car quickly jerked back into traffic and I was forced to take control before accidentally hitting another vehicle the vehicle continued to go into another direction and did the same thing several times later. I put my home address in the navigation to go home, but as soon as my Tesla was about to turn right into my subdivision it quickly pulled and jerked me left back into traffic and took me completely into another direction several days again. I let the car complete its misdirection and the car took me around the block into a parking lot and bought me back to my original planned destination to my home.

While operating a 2025 Tesla Model X on full self-driving (fsd supervised), the vehicle engaged in leader-car following behavior and trailed a slow-moving vehicle onto an active railroad crossing. Fsd failed to ensure the exit path was clear, causing the vehicle to suddenly decelerate from 12 mph to 0 mph, stranding the car directly on the tracks just as the crossing's active warning lights and gates triggered. When attempting to take immediate manual control to clear the tracks, the vehicle suffered a severe drivetrain control lockout. The vehicle remained unresponsive and stuck at 0 mph for approximately 3 seconds despite driver intervention to shift into reverse and accelerate. After the 3-second software lag, manual control was recovered, and the vehicle reversed. A dropping railroad gate arm struck the vehicle's panoramic roof and hood during the escape. Telemetry stats and multi-camera dashcam video of this autonomous software failure and control lockout have been retained.

My Tesla Model X was in autopilot mode (v13. 2. 9) at the time of the incident. The vehicle’s advanced driver-assistance system was actively controlling steering and speed, while I remained attentive with my hands on the wheel I was closely monitoring the car’s operation but was not manually steering, braking, or accelerating during autopilot engagement the vehicle collided with stationary flexible delineator posts. The impact occurred at 55mph. The flexible delineator posts were the only object struck. No other vehicles were involved in the accident, and no persons were injured. No passengers or bystanders affected. The collision with the flexible delineator posts caused damage to my vehicle’s front bumper area and cracked right headlight. There was no damage to any property besides my own vehicle. The incident was captured on the Tesla’s built-in camera system (dashcam). I have saved the video footage, which clearly shows the car’s approach and the impact with the flexible delineator posts. This video is available and can be provided for review.
