Intermittent electrical problems on my 2004 CTS

Lately I have had intermittent electrical problems with my 2004 CTS.
Sometimes when I start the car it initially greets me with my personalized message, but then a few seconds later it's switching to "Home settings" and all my stations and customizations are gone. If I press "1" on the door panel or press "unlock" on the remote it might briefly switch back to my settings but quickly reverts to "Home settings" again. Other times the door panel buttons or the remote buttons have no effect at all.
If I turn the car off and then restart it everything usually works ok again….
I have also seen problems when locking the car where the driver side lock doesn't always work even though the horn sounds to indicate the car is locked….
Has anyone experienced these problems? And what could be the issue?
It's out of warranty and I am afraid of taking it to the dealer and have them spend a whole day replacing everything from computer modules to sensors and locks….
