Complete MCU Failure

Good luck and let us know your thoughts on MCU2! Getting my upgrade a week from Monday. Already had one appointment cancelled due to lack of parts - after I got the message telling me the parts had arrived! My MCU1 is on the fritz and I think my last call to service is what got me back on the MCU2 appointment list, because while they were trying diagnose my issues they asked if I wanted MCU2.

It seems odd they are still experiencing a parts shortage. I assume the quantity needed for upgrades must be a very small percentage of the volume they need for the new production vehicles.

Lost my center screen, backup camera, TPMS, AP and cruise control, Slacker, radio, nav, charge timing, outside temp, half my motor power, Homelink and access via the app. Still drivable and headed to the SC Monday for the MCU 2 upgrade.

D'oh! Did you have the MCU2 upgrade scheduled already?

Just got home with my new MCU2, haven't really had a chance to wring it out just glad to have a functional car again. Just in time too, car was unwilling to charge at home last night and luckily I had enough zap to make it to Santa Barbara. I ordered the unit long ago but think my MCU failure speeded the process as they overnighted the part.
