Wow at the Pump
I I clarify that the 6.6l is in my 26 Sierra 2500HD Ultimate. My wife has a 25 Yukon XL Denali with the 3.0l diesel. Can't beat more than 500mi to the tank!- Nautilus571

Wow at the Pump
One of many reasons I love my 6.6l diesel! Prices have dropped more than $0.50 a gallon over the past couple of weeks. The membership clubs like BJ's and Sams are even a dollar less a gallon than that.- Nautilus571

Aftermarket "Authoritative" Horns -- What Experience/Recommendations Do You Have?
I would like to install the loud obnoxious train horn on my 25 Sierra HD that would use the normal actuator on the steering wheel. But I don't want to have to disassemble the entire front end to install it... guess I'm stuck with stock... smh- Nautilus571

No sounds
My 2025 Sierra HD did this on me twice. I parked it, turned it off, let everything shut completely down (all this clicks and clacks) for about 30 minutes, started it back up and everything worked. What really blew my mind is the turn signal clicking is actually coming through the audio system...- Nautilus571

New 2025 Z71 Diesel Owner – Excited to Join!
In the past month I purchased two new GMC vehicles both being diesel. First diesels for me as well. I purchased a 2025 Sierra 2500HD Denali with a 6.6l Duramax for me, and a 2025 Yukon XL Denali with a 3.0 Duramax for the wife. So far no complaints. I just can believe the range indicated for...- Nautilus571

Another 6.2 failure
Owners manual specifically states to use only premium grade fuel. Anything else will result in issues with the engine.... I have a 2019 Sierra Denali with 44k mi and the 6.2L L87. Love it. The only issue recently like in say the last several thousand miles is oil evaporation. Shortly after an...- Nautilus571
