Common Issues with Tesla Model Y's Power Seats

The Tesla Model Y is equipped with a range of advanced features, including power-adjustable seats. However, some owners have reported issues with these systems. Below are common symptoms, diagnostic steps, tools required, and repair instructions for addressing power seat issues.
