For the last week now, the whole center console (navigation, radio, climate controls, etc.) on my 2012 F150 will just go out while I'm driving. Sometimes it will come back on in a few seconds, sometimes it takes 5-10 minutes, sometimes I have to turn the vehicle off and then back on.

I have the extended warranty through Carmax, so I am covered through 100K. I took it into them and the screen was off, and the person checking in the vehicle confirmed it was not working. But of course, when the technician restarted the vehicle, it was working and he has no idea what is wrong nor how too diagnose it since it is working.

Any idea on what to have them investigate next?

 

Only thing that comes to mind is a loose connection. Try disconnecting any wiring that goes to the unit several times. Just pull it off and push it on several times to try to clean the terminals. No guarantee it will solve your problem but it might.

Good Luck!
