The incident involves the malfunctioning of the Tesla Vision and Parking Assist systems in my 2023 Tesla Model Y. Over the course of owning the vehicle, I have experienced multiple issues with these systems that led to three parking accidents and safety concerns. On several occasions, the Tesla Vision system displayed a message indicating "Tesla Vision will experience degraded performance." This message appeared consistently, signaling an ongoing issue with the system's capabilities. The degraded performance of Tesla Vision was particularly evident in its inability to accurately gauge distances and detect obstacles during parking maneuvers. The Parking Assist feature, which is crucial for safe and efficient parking, also exhibited significant flaws. The system failed to provide accurate distance measurements and warnings, which are essential for preventing collisions. This was especially problematic in tight parking spaces and while maneuvering near obstacles. Specific incidents of concern include: 1. A parking accident occurred when attempting to park in my garage. The Tesla Vision system failed to accurately detect the garage door, resulting in a collision while exiting the garage and attempting to turn the car. 2. Another incident involved a collision with a white column positioned against a gray wall, which the Tesla Vision system failed to recognize, leading to vehicle damage. These incidents highlight the unreliability of the Tesla Vision and Parking Assist system
