Well boys... Looks like replacing the sway bar module didn't fix her. I picked it up this morning, drove it back to my work, got back in it to go fix a flat tire on my wife's car (when it rains it pours), and there went the sway bar light flashing and no start... I couldn't believe my eyes. I called the dealership back and they sent their master tech and director of service out to my job to look at it while it was messing up. By the time they got there.. problem gone... I have a couple videos on my phone of what it was doing which I showed them but how good is that??? At least they know I am not crazy. Oh well... Back to the drawing board.

- rattling coming from front end (turned out to be sway bar disconnecting briefly, intermittently)
- manual shifting (auto) would hesitate or jam and take numerous taps of the shifter to finally shift to a higher gear
turns out the shifting would be delayed due to the fact the BUS line was busy with the e-disco communication

Sway bar e-disco uses the same BUS line as various other systems. Being that they use the same "road" of information it can cause issues. I recently had my whole sway bar system changed and it fixed a couple issues which seemed at the time unrelated.

I noticed in the fuse box that the same fuse for the sway bar feed is also the one for the fuel pump relay and a couple other things. They contacted some high finagled engineer to help so... maybe he will. Keep yall posted.

Okay latest update. They said the system just needed to be flashed so they did that today. I tested out the sway bar twice in the parking lot before leaving and it worked just fine. No flashing light.
Fingers crossed!

Thats great news, I am really hoping at least one of ours is fixed! haha, but I have a couple questions about the fix they did. I wonder how the figured out the system needed to be flashed? What consists of a "flash" and what exactly does it do really? Maybe thats a dumb question but I have no idea the answer so maybe someone could help me there. Also, did your jeep ever run weird or would crank over but not actually run when the sway bar light was flashing? I just stopped in the dealership for a visit and showed them the videos I have of what it's doing which seemed to help them understand alittle.... or not...we'll see. The tech said that low voltage from the battery can cause issues like this, which is what a couple people here mentioned, but he said my battery seems fine. He also said he is going to e-mail some stars something or other to see if they can help.

A flash is just a computer update as far as I know. So since they replaced and electronic part, they had to tell the computer to play nicely with it. That's my guess. I could be making things up.
So if they replaced your actuator but didn't do a system update that could explain your problem.
As for whether or not I had other issues, yes, my Jeep was going into whatever I can describe as limp mode. It would downshift, engine fan would come on, and it threw 24 error codes including ABS not working, couldn't detect fuel level, etc. Luckily I could clear those with my Flashcal.
Never had it not start but I also left the unit unplugged when all this started happening so that it was still drivable.

FINALLY!!! The dealership actually got to witness the jeep doing it's "thing." Bad part... no idea whats wrong. But at least they know I'm not crazy here. They are leanin towards a bad spot in a harness somewhere.
