I am writing to report a concerning incident involving the full self-driving (fsd) feature on my 2026 Tesla Model Y. The incident occurred on Saturday, may 24, 2025, at approximately 8:30 am edt at the intersection of lee road and diplomat circle in orlando, florida. My wife and I were traveling from safety harbor, FL to foxtail coffee on lee road in orlando, a trip of approximately two hours. The fsd system performed well for 98% of the journey. However, at the aforementioned intersection, the vehicle was stopped at a red light in the left lane, first position, for approximately 45 seconds. Suddenly, without warning, the car accelerated and ran the red light. Thankfully, there was no cross traffic, and no collision occurred, but this was a frightening experience that significantly undermined our confidence in the fsd system. Even though we love the vehicle, we felt the need to report the incident.
