Had a 2018 Sierra 2500 for a loaner while my 1500 was having warranty work done. We got a couple 0 degree days here in St Louis during the polar vortex and the 2500 went into limp mode and wouldn't allow me to go above 25 mph. CEL came on and a message popped up "Reduced Engine Power". I was 30 miles from the dealer that loaned it to me and they sent someone out and gave me a 2019 Silverado 1500. Next day they towed the 2500 back and found the diesel fuel had "gelled" from the cold temps. Curious, is this common in diesels? I let it warm up for at least 5 minutes before driving as I know diesels need a little more warm up time than gas engines. How could it idle and drive up to 25 mph with the fuel "gelled" as the dealer put it? Didn't shake or sputter, just had the rpm limiter kick in at 25 mph. -
Hello, I am desperate for any assistance that can be provided for our situation. We are US military stationed in Germany. Our 2015 Sierra recently threw the p21dd code. We ordered the replacement reductant tank and installed it ourselves. The engine codes were cleared but we are still getting limitations on our speed and distance. We are stuck at 88kph/80km until we drop down to 6kph. In the research that I've done so far, it seems we need a manual regen done on the truck in order for the limitations to go away. This is where we are having the biggest issue. GM will not assist us in any way because we do not reside in the US. They constantly revert us back to the German GM entity and I've lost all hope in trying to communicate with them. We have been hung up on more times than I can count because we do not speak German. So, is there any hope for fixing our vehicle before it goes limp? If we can't get it fixed, we don't know what we will do as we cannot sell it in this state, we can't ship it in this state, and we definitely can't drive it. We are struggling to find a light at the end of this tunnel and would greatly appreciate any help available.

Hi, 2001 GMC C3, 6.0 keeps going into limp mode. Need help. Its been to numerous legit mechanics, everyone thinks they know the silver bullet fix. Always fixed for a week or so, then it starts again. Has had TB replaced, all all associated possible problems, wiring, wiring, wiring, knock sensors, etc. etc. Been struggling with it for over a year. Nice truck, would like to keep it, otherwise trading it in and gonna stick GMC with it. Dangerous to drive it anywhere but local. Anyone have any suggestions? It has onlly 130,000+ miles on it and runs fantastic when it isn't in limp. HELP!
