Tesla has seen a wave of high-level executive departures since early last year, including key figures like CEO Elon Musk's confidant, Omead Afshar, chief battery engineer Drew Baglino and global public policy head Rohan Patel. The head of Tesla's Optimus humanoid robot team, Milan Kovac, announced he was leaving in June, and top battery executive Vineet Mehta did so in May. Their departures, along with others in legal and supply chain leadership, have raised questions about internal stability at the company as it navigates a sales slump and a shift to robotics and self-driving technology.
