Thank you so much for this amazing detail!! I was able to follow the exact instructions, photos, service bulletin and the YouTube video you included that helped me get the job done myself in just a couple hours. To people reading this post currently: this only has to do with the vehicle shorting out when you hit a bump. This issue has been bothering me for about a year now and I have spent hours looking for answers. I have a 2015 Tahoe Z71 and it seemed to run better instantly after this change.

My 2015 Tahoe does this same thing over big bumps. I found this thread and he even included a GM Service advisory on the ground wire on the driver side dash, it's deep in the corner under the windshield. I did it yesterday myself and it wasn't a major issue. The insulation was exactly how they said it would look like. Dash went back on no problem as well. Here is the link with all the info you need and make sure this applies to your year/model vehicle. This guy did major homework and really provided all the info to get the job done.
