About a month ago my MFT when unresponsive. I could touch the screen, but was unable to control the radio or other functions via the touch screen. The voice control button didn't work either. I performed a reset on the MFT, and still was unable to use the touchscreen or voice commands. I was planning on taking it into the dealer to get it looked at. Before I was able to schedule the visit with the dealer, my battery was dead after sitting for ~12 hours. We had nothing plugged into the USB or 110v ports. I got it jump started and the MFT and voice commands returned. I took it into the dealer a couple of weeks later and mentioned this incident, and they performed this TSB. All has been well now for a couple of days. Just providing another data point.
