    6.2L Rough idle and poor low RPM response

    Our 2023 exhibits the same characteristics from time to time, but much more prevalent in the first few thousand miles (like nearly all the time). Dealer never found anything wrong and now at 17000 miles it is mostly smoothed out.

    illuminated running boards

    Half the lights on my passenger side work, so sounds like i need that same thing done. Glad to hear it wasn't a big deal. Do you remember if they had to order parts/keep the vehicle an extended time to do this?

    2023 GMC Yukon AT4 6.2L dead at 10K miles

    My dealer service department said the same (and they are a very high volume dealer). The forums seem very scary about these 6.2L engines but they sell how many of these a year vs. how many reports we see on this forum? I'm up to 14k miles on our 2023 and expect to run it up to about 75-100k...

    Recirculation Issue

    Same here...the recirc doesn't seem as effective at alleviating outside smells as in our previous (non-GM) vehicles. Not enough of an annoyance to check into service for (especially with no loaner programs).

    2023 Yukon Denali 6.2L Idle Vibration - Normal?

    I would swear its related to the low idle but keep reading about fuel injector issues being a new-ish problem. Maybe I'll try a couple tanks of the name brand top tier gas, rather than the place I've been using. I'm only at 1300 miles.

    2023 Yukon Denali - Satellite Performance

    Thanks everyone. Sounds like a standard quirk of the system I'll have to adjust to.

    2023 Yukon Denali - Satellite Performance

    Since new, my SiriusXm reception on my new Denali seems to pause/refresh 2-4 times in the first couple minutes of driving. Clear skies/not under a bridge/tree/etc. Does everyone else have this issue to some extent? I've thought about having a fresh signal sent by Sirius to the vehicle, but...

    2023 Yukon Denali 6.2L Idle Vibration - Normal?

    Hi All. New owner here. Since i first took delivery at 5 miles, I've noticed a intermittent vibration at idle, mostly when stopped at stoplight - felt in seat and floorboard. Like a slight kick. I've read alot about idle vibrations due to lean mix/low idle speeds for emissions - is this what...
