So a couple weeks ago my facelift 2016 Model S greeted me one morning with a black MCU screen. The car still started and ran, but no HVAC controls or radio or blinkers as far as I could tell. So I immediately made an appointment through the app for service and the car has been down there for one week today. My car is just a few hundred miles out of warranty so I figured my only options were full MCU1 replacement or what they call now the infotainment MCU2 upgrade. Come to find out that because my car doesn’t have a power lift gate that the infotainment upgrade is not an option as of now. So I just got off the phone with Tesla service here in Reno and they tell me they are now replacing the Tegra card and that my total in parts and labor for repair of the MCU1 is $490. I glanced at the estimate and it looks like the Tegra card is $120 part and the rest is labor and diagnostic fee. It seems pretty palatable since I thought I was going to be in at $1000 or more for a repair. Just thought I would relay my experience for the benefit of others. Also they told me that part could be a week or two away.
