NHTSA Complaint #11492220 — 2017 TESLA MODEL X

MCU failure. Same symptoms as a failure of the mcu1, although mine was upgraded over a year ago to mcu2. It has failed. Failed strangely enough, after leaving the dealership, after an unnecessary recall to update MCU memory. My car does not have the problem. I was told, and given the car back. a mile from the dealership I realized that nothing was working. Can not turn on the defroster cannot operate any other features, air-conditioning, etc. it took three months to get the car back to them to try to address this problem all the time not having a fully functioning touchscreen and after two week time at the dealership they tell me that the MCU has failed and then I have to pay almost $2000 to fix it, additionally, they also said that this is the first MCU upgrade to the MCU to that they have seen fail, which brings up a whole lot more question. Carl was working fine when it entered the dealership to perform this unnecessary repair, but was not working when it left.
