Well the saga continues. It worked just fine for about a week and and now it is having the same issues. Talked to the dealer again today and they finally admitted mine was not the only one. They claim Lincoln has no fix at this time. SYNC 3 was supposed to correct all the problems. Looks like this is going to be a sequel to SYNC all over again.
Issues to look for.
1. Screen goes black and blank after start up and can not be recovered, even after shutting the car off and restarting. Everything works fine the next day.
2. Screen goes black but controls are still visible and function normally.
3. Screen goes black, controls are still visible but are frozen and do not function.
4. Screen is normal, controls visible and function, but can't switch from one screen to the next. (audio to Climate)
Any of this sounding familiar? This is a 2017 MKC with less than 1000 miles on it purchased new in November 2016.
If any of these issue show up on yours it is not a fluke. It will continue to happen more regularly as time goes buy. The backup camera continues to work normal during the problems, so it appears that it is not the screen it self.
