SOLVED!!! I had all the same exact symptoms described and discovered my airbag module was corroded!!!! See Pics .Major part of KBUS issues. Advise all to at least check it out.. Just unplug it and everything works properly !!! Be advised your airbags won't work unless you replace the module. Also, you don't
have to remove the entire center console to just unplug the airbag module, just need to remove the upper portion between the seat backs...kinda tough if you cant get the top down, otherwise it can be accomplished at home. There are some YouTube videos on removing the center console, but watch the latter portion to see how to remove only what you need to move...I learned the hard way!!! Good luck.
