If you haven't solved this yet and did what I did (which was park my truck), well, I lived your nightmare for the past 5 years or so. Took the vehicle to a Michigan dealer as well and they kept replacing expensive part after expensive part and ultimately, I was $4,000 in before they claimed it was a wire harness with bent pins that then also had to be replaced. This worked for about two years and everything started happening again. I took it to other local mechanics (including one that had the TSB) - everyone gave up and my Yukon was parked for the past 3 years with only some short drives here and there.
But I fixed my problem! I'm now up to 1700 miles without an issue and as you'll see from my other thread, I have very little experience working on vehicles, but do a ton of research, watch a lot of videos, and wholeheartedly listen to the great people here.
I kinda went slow with things...cleaned up a ground here, a ground there - some were a mess and needed it. But, none of those fixed my problem. It wasn't until I replaced the negative battery cable (that comes from the battery) that fixed all of my issues. While I was at it, I also replaced the positive battery cable that goes to the under hood fuse block as well.
Please take the advice from everyone else here before me...I'm just a rookie at this, but I was able to solve my problem on this one.
If you decide to do this, I'll dig up some of the videos that I used - there is one hard reach, but other than that, it was just basic tools.
Best of luck!
