I hope someone can help.  Recently bought a 2011 C2S.  Memory setting for 'key button 1'  and 'person buttons 2.3' do not work.  Following Owner's Manual instructions, but get no "beep" or any other indication that settings were saved.  Pushing buttons results in nothing.  I move seats all over, make the 'save' and nothing works when I press the buttons.  Is there a trick I do not know, or is something broken?  Thank you.

How about key #2?  Does it have same behavior as key #1 with the three buttons?  I get the confirmation beep each time, all three buttons and each key. 

 

If key #2 has the same problem, maybe there is a bad fuse for the comfort settings.  If you have access to a Durametric you could try to see if there are any codes or a reset.  Outside this it may be a dealer trip is warranted.

I had exactly the same problem. Turns out the CAN bus control module which controls the key memory and light at the bottom of the door was loose / disconnected (behind the door card I think). If your door light does not work that's a pretty good sign that you have the same (or similar) problem.

BTW, I assume that you held the "1" (or 2 or 3) key while pressing the "M" (Memory) button to save the setting(s) ?

I have similar problems: white lights in doors flickering; passenger-side window doesn't auto-up, sometimes doesn't auto-down; reverse mirror setting can't be changed; and key programming can't be changed. Do you know how to access and check the fitment of the CAN bus control module? Has anyone identified other culprits for these problems? Also, the after market Dynavin stereo seems to spontaneously power down.
