TCU ISSUE: Hoping for comments/ suggestions. My 2021 Turbo Creo worked fine for 2.5 months. Then the TCU started acting funky. It will turn on but only stay lit for a few seconds, then go dark. The motor works fine and I can adjust assist levels using the handlebar remotes, but the assist level and the battery level do not show up on the TCU because it is dark, and keeps going dark in a few seconds after restarting it. The manual shows there is a coin cell battery in the TCU, but I wouldn’t expect it to be depleted in less than 3 months, and I don’t feel competent to take the TCU apart to replace the battery. Mission Control shows all software is current. I am a great distance from a dealer. Thank you for comments/suggestions.
