Is this by any chance with the premium radio with 6-CD changer and automatic heater/AC controls?
If so, there's a problem that causes the controls to freeze -- bad solder joints on a printed circuit board in the radio. There are posts here about it, including at least one where a member indicates what was found on the board and how it was fixed.
If it's not the premium system then, as far as I know, it's not something I recall being reported here before. But the intermittent nature would also suggest poor contacts -- possibly bad solder joints, or a loose/contaminated connector contact.
Let us know if it's the premium radio and we'll go from there, or do some searching with the search function -- the other posts should come up.
