    Tahoe Constraints - 1/27/22

    This should be an option, that's how my Denali is.

    Vibration on acceleration

    Thank you and sorry for the vague description. The noise is only for a second or two and then nothing and is not consistent. Tire pressure is fine and I have stock 22s. Going to check the engine bay to see if there are any loose wires, etc. it sounds like light plastics bouncing against each...

    2022 Z71 - how to keep it in sport mode?

    any thoughts on whether using sport regularly can hurt long term engine reliability?

    Vibration on acceleration

    2021 Denali. Hearing a slight vibration (almost like a cellphone buzzing) when accelerating. Mostly happens on right turns. Sounds like electronics or plastic pieces touching and vibrating. Any ideas?

    Baby’s first check up.

    Glad to hear about you and the pup enjoying the truck. Still haven’t let mine on the 21. They are reserved to our 1999 mountaineer.

    Which build months are safe from lifter problems?

    I just posted about the rough idling on my Yukon. Would be interested if you understand what I am describing.

    Brand new 2021 Denali shuddering

    So I just found this video on YouTube. If you watch at the 59 sec mark, the RPMs slightly waiver a bit after start up. This is exactly how my truck behaves. Hope this is a helpful example. Seeing it on another vehicle makes me feel it is normal and nothing to worry about, but I would be...

    2021 Yukon no heat

    Haven’t had a need to use the heat yet but will give it a shot now to be sure … might be a one off. Sorry to hear about your trouble and hope it’s not too cold where you are.

    2021 Yukon SLT or 2021 Tahoe Premier

    I would go with the premier for the added options. Albeit you are in Florida, I would rather have the 4wd and not need it than need it once and not have it. Not a huge fan of the SLT front end. Magnetic suspension should be a huge advantage over your Ford truck but I agree the SLT will still...

    Brand new 2021 Denali shuddering

    Good to know, thanks. What I am describing is a slight fluctuation in rpm (+\- 50) from time to time. It’s very minimal but noticeable. I have other vehicles that behave similarly but I may be hypersensitive in this situation. Not sure but will continue to drive, enjoy and monitor.

    Brand new 2021 Denali shuddering

    Yes it is black - thanks, I can’t help staring out the window at her myself. Going to enjoy it until there is a good reason to be concerned, but may call the dealer for insight before going in as well. I am not one to try and shut off the DFM until there is a known, reliable method...

    Brand new 2021 Denali shuddering

    Thank you! Good to know. How many miles do you have on your Tahoe? I think I am going to try and get past the 500 mile break in (per owners manual) and a fresh tank of premium to see if any improvements. I have dfm but no auto stop/start. Appreciate the insight.

    Brand new 2021 Denali shuddering

    First, I want to say I did not join the forum to complain. I have had my 2021 Yukon Denali for a week and I love everything about it so far. I am noticing a slightly rough idle. I don’t even know I would call it rough. Very slight rpm fluctuations and a couple faint shudders. I have a September...
