I just experienced my Tesla MCU screen black-out.
My vehicle is a 2015 Model S at approximately 45,000 miles.
I was making a quick trip to the grocery store and upon returning to my vehicle, the MCU screen turned black. I thought it was going to take a while to load since I've been experiencing slower MCU functions ( the msg "please wait while vehicle powers up" plastered on the dashboard for the past 6+ months), but after attempting to reboot/reset, the MCU screen remained dark. The blinkers were not working, the AC unit was turned off, and I had no control over the headlights and other standard functions/adjustments. I'm starting to think that this is a pretty big issue in regards to safety because I probably would have called a tow truck if I wasn't just 5 miles away from home.
If the MCU was merely for entertainment purposes (radio/apps/seat warmer..etc), then maybe it can be brushed off as a vehicle part that is permissible to deteriorate over time/usage. Tesla's MCU1 chip, based on what I'm reading here (if the vehicle is pre-2018 and fitted with the original 8g chip) then MCU failure is inevitable - it's just a matter of time. This is concerning because they're basically selling a vehicle that is guaranteed to fail after certain limitations of time/mileage/usage. It's a pre-established vehicle part failure that applies to a large number of manufactured vehicles grouped by year-made, and follows a systematic pattern of issues and failures. I don't know how much more needs to be proven that this is in-fact a manufacturer defect that Tesla is strictly liable for... considering this is almost a textbook issue for manufacturer recalls.
If your out of warranty we can help you. The first post on this thread has all the information. Also, AFAIK in the past any recall would reimburse owner for repair of failure even if repaired 3rd party.
