Has anyone seen this issue before? If so, what was the cause of the failure? I was traveling home from deer camp Friday and it blew apart. I zip-tied it together and made it about 2 miles and it blew apart again. I found a hose clamp in my tool bag, put that on tightened it down with small channel locks. I cleared the codes with my scan tool, and went about 30 miles and the codes came back and it blew apart again. I pulled off the side of the interstate and called AAA. I had the truck and my 30' toyhauler both towed to the nearest town. It is sitting at the dealership waiting on a new pipe/hose. Something is causing an overboost condition. Apparently GMC has this as the weak point intentionally in the case of an overboost condition. 2023 with 29,000 miles and zero previous issues.
