Update:

 

So still running into this issue.  Hoping I finally caught a code this time.  During this “no start” forscan picked up code U0253-20 - Lost communication with accessory protocol interface module.  Module Restraint Control Module.  
 

After waiting a couple min and trying again the engine starts no problem.  Subsequent checks for codes show nothing.  Before I start changing out the RCM I figured to run it up the flagpole here to see if that even makes sense for this to be the issue.

I have the same problem, finally after years found a code pointing to the RCM.  Did you replace it and was the problem fixed?

I have a 2012 Edge, and this on again off again starting problem is driving me crazy and the dealer, who's had it for a week now for the second time and still can't replicate the problem. So he wants me to pick it up again and see if we run into the same problem again. We already replaced battery, the ignition switch, and a relay, each time the on again off again starting problem returned. I would like to know more about that exposed wire under the carpet fixing the problem, which could be what I might need my dealer to do. How did they ever figure that out? I have so far seen three problems like this but no clear fix, other than the posted here.
