I went out to the car today (late 2015 P90D 27K mikes) and the drivers screen said, "Please wait for your Tesla to Power Up." I waited 3-4 minutes and the screen in front of the steering wheel came up. But no touchscreen. I tried the brake and holding in the 2 wheels on the steering wheel. No change or reset. I called Tesla and they actually answered. That is rare in So. Cal. He said the MCU is out. Not the 12Volt battery since it was replaced. He wants it brought in to a service center. I have purchased the extra 4 years of warrantee so I would guess it is a $200 deductible. Is it possible this happened from the recent update of a few days ago? Any thoughts would be appreciated.
