Thinking of selling my new 6.2L Denali...
I changed mine every 4500,full synthetic and it grenaded at 27,000. I would never go 7500, let alone 4500 as these things are known to consume oil also- Hiebs

1000 miles from home dead 2022 Denali
Not dead, ticking so loud it was amazing that it wasn't, dealer didn't understand how it wasn't dead, no dash lights, nothing, even mechanic at dealership didn't understand how I made it there, they said normally it shuts the truck right down.- Hiebs

1000 miles from home dead 2022 Denali
I know it can be repaired, my issue is having to take time off work and have someone drive me a 1000 miles to pick up the truck, that's the ****** part, and I doubt they'll give me a courtesy car or rental to use for the duration that I'm without the truck.- Hiebs

Hi guys, long story short, 2022 Denali, 6.2, runs great, shifts fine, UNTILL I give it the juice. If I'm at lower speeds and hit it, the trans feels weird , like it's bumping or almost slipping, does it 80 percent of the time, normal city driving it seems fine, but when I punch it to get on the...- Hiebs

2022 Yukon driver side floor soaked!
Been to dealer 5 times now, they say they can’t find the leak, I’ve shown them videos of water pouring out from under the drivers side dash, but that’s not good enough, they keep telling me they need to see the leak to see where it’s coming from -

New 2021 Yukon 6.2l cabin noise
Any updates , i have a 22 Denali, same issues, I get headaches driving the thing, I can’t figure out where it’s coming from, also has tons of road noise, my 2020 ram rides way nicer and much quieter, sure makes me mad, for $85,000 it should be much nicer.
