Odd electrical system problems
My 2012 CLS550 started having a strange series of electrical problems:
--the heat controls go crazy off calibration, requiring huge temperature adjustment. Next day, they are fine again.
--Audio disappears. Each song or message consists of only a slight click and no other sound. Next day, sounds are okay.
--The main control knob for the GPS starts doing nothing when you press down on it. Later, it works fine.
I am NOT seeing any flickering lights, error warnings, etc. This makes me suspect that this is more likely some sort of message-passing fault in the computer system, rather than a power problem, but of course I can't be sure.
The car was into the dealer, and the dealer did not find anything in diagnostics.
Has anybody seen such problems, or figured out how to get them fixed?
Thanks !!!
