I noticed on on the day before yesterday that my sat radio had lost all 12 of my presets. All of them went back to saying "Hold to set" or something like that.
I gave it a few key cycles, hoping they would come back, but they never did. Yesterday, I finally gave up and reprogrammed just preset #1.
Today, that preset was lost again. I also noticed today that it had lost my customization of the button bar at the bottom of the screen. I had replaced the Backup Cam icon with the 360 Cam icon, but today it had gone back to having the Backup Cam icon in that spot.
I've only had my truck for 3 weeks. I think the build date (month) was 3/19.
