The MCU on my 2013 MS stop working about a week ago, and I just stumbled upon this thread. Now I'm debating whether I should:
1) Take it to Tesla and pay out of pocket for an MCU1 replacement, and hope that it's later recalled and get reimbursed.
2) Go to ev-fixme for a 3rd party repair, which should last longer than a refurbed MCU1, but I think will be much harder to get reimbursed, if at all.
For my vehicle, the turn signals no longer work (not just audibly, they don't light up either when the car is in Drive). The headlights and AC luckily come on, but I have no way to control them. No parking sensors, rear view camera, or autopilot.
