The driver seat, seatback, will recline if you leave the vehicle running and exit the vehicle. Seems once you leave bluetooth or key fob range, is when it happens. And it happens very often, most every time. I had another 2026 Tacoma Limited hybrid and it did the same thing. So it clearly isn't a "just me" or "just this one" situation, it has to be happening to others and hasn't been reported yet. The seat back will recline all the way back until it touches the rear lower seat cushion.
