2024 Duramax COLD START in Freezing Temps (FAIL) GMC Sierra Denali 6.6L Diesel

Welp, the video is self explanatory. I really had high hopes for this thing in the cold, but was let down. Not only did it not start, but it wouldn’t let me stop the “cranking” process so I can further diagnose or let the glow plugs warm up. It just had a mind of its own as you see in the video. 2024 GMC Sierra Denali 2500HD 8ft bed with the 6.6L diesel. This is the second time I had “service emission system” pop up. See my last video on it where it randomly happened in a heated warehouse. Going to have it towed to GMC and have them deal with it. My next cold start video, I will make let the glow plugs warm up a while before attempting again. Then, I’ll make one with the block heater plugged in and see if that helps any. The point of these videos is to simulate various situations one might be in, and how the truck handles it. I love my 2024 Duramax, but it has had its fair shares of little issues. Shoutout to warranty lol! Thanks for watching, and stay tuned for updates. Also, comment below your experiences and also what you think of this situation. Any tips and advice are always appreciated as well!
