2016 Infotainment System will not Dim

Infotainment system will not dim when the lights come on as of tonight ... 8th day of ownership . Dim control in settings does not work at all. And when I turn the lights on if I tell it to turn off the display and back on it comes on dim ... But then. Will not brighten back up.

Tried to restore factory display defaults and get a message saying it is unable to restore.

And the command to restore all factory defaults is grayed out

So it seems totally screwed to me. Firmware is .51

Any ideas other than a trip to the dealer?

Can still control the dim functions with the odometer reset knob?

No nothing would dim the info center .... Only if I turned off the display and back on ... But then it would not brighten back up if I turned the lights off ... AND the dim and auto feature in the settings had no effect

... But wait ...

Third times the charm ... After starting the car after dinner to discover it would not dim. To stopping on the way home to restart the engine, which had no effect. Then messing with it in the driveway with no effect .... An hour later, when I went out to the store... It worked flawlessly again.

WTF???

Wondering if the .55 OS update will help or solve the problem .
