Hi, my MCU was change last year in July 2019 CPO under warranty. I believe my MCU is going to die soon (Out of warranry). I just did a new software upgrade and it stuck again at 80%. SC try to push to redownload it and still stuck at 80%. Last previous software upgrade it got stuck, was repush and got completed. Not this time. Everything still back to normal. I can drive, use radio, fan, etc. just unable to do software upgrade. Only the right scroll wheel and 3G is disable, but WIFI work. I check on tesla website: Vehicle Warranty it said this: Touchscreen and Media Control Unit: 2 years or 40,000 km, whichever comes first i check the detail on this PDF: https://www.tesla.com/sites/default/files/downloads/tesla-parts-accessories-body-repair-limited-warranty-en-us.pdf first page said: EFFECTIVE DATE: JULY 2, 2020 does it mean, my MCU does not apply to the warranty since it got replace last year 2019? We have something call legal warranty in Quebec that state "The legal warranty says that, if a merchant sells you something that isn’t of good quality, durable, safe and in line with any expectations created by the merchant, you can, among other things, get a refund or have the product replaced. The legal warranty also protects consumers against hidden defects." but It take time to get thing resolve. Will only use this as last resort.
