Two problems related to software have been reported for the 2016 Tesla Model X. The most recently reported issues are listed below.
My touchscreen went black and systems became disabled (air control, autopilot, music, navigation). Within a week the readings on my phone app were not correct and it took some time for the power to engage the gears. My backup camera went dark. Finally, I could not put my car in gear and it had to be towed by a specialty towing service. Tesla tells me it is a software issue, but I think a memory chip has gone bad. I think this relates to an existing investigation on this issue by NHTSA.
The contact owns a 2016 Tesla Model X. The contact stated that the touch screen media control unit failed. The vehicle was taken Tesla (470 lancaster Ave, devon, PA 19333), and the software was updated and the computer was reviewed. The contact stated that on another occasion while driving, the screen deactivated and returned to normal function independently. The contact stated that the failure caused the turn signals, air conditioner and wipers to lose functionality. Additionally, the failure caused the vehicle's driving range to be limited to 40 miles. The vehicle was not repaired. The failure mileage was 63,000.
