I just sold my 2021 Denali 6.2 for 63K. I put around 3,500 miles since December and originally I paid 59K (original sticker was 69K). First time ever for me a depreciating asset, a vehicle, turned into an appreciating asset.

I just looked at trading into a Denali with the CP bed. There were no back fender well liners and I was told those are not available with this bed. Not sure if true but it didn't look finished without them. That was a negative along with the lack of variety in bed covers.

Wow that sucks. Makes my issues seem minor in comparison. My 6.2L sounds like it has an exhaust leak and evidently it is the fuel system so I'm told and completely normal even though other trucks on their lot don't do this with the same motor. Also my bed looks like Stevie Wonder aligned it. Taken to dealer twice and evidently if there are no trouble codes and it still drives there is nothing they can do. Very disappointing when thinking about how much these trucks cost. Hope you get some resolution.

My 6.2 makes this noise when started first thing in the morning and also under acceleration between 1,000 and 2,000 RPM. Took it to the dealer and of course they say it is normal. I believe it may be the high pressure fuel system. They basically told me if there are no CEL lights and nothing evidently wrong I had to live with it. It drives me insane on an over 60K truck every time I drive it. Add that to the out of alignment bed and I am not happy at all with this purchase.

I agree completely. Also even if something doesn't look and sound right as long as there is no CEL or trouble code then there is nothing they can do.

Yea mine still does this but only under light acceleration. More like a rattle than a tick I guess. It is annoying. My 2019 5.3L didn't do this at all.

I have a rattle sound under light acceleration between 1-1.5K rpm. Not sure if this is like yours. Not my video but sounds just like my truck, a 2021 6.2L (Turn up volume to hear it). It's driving me nuts especially on a new expensive vehicle.

Mine does this too. May be ice accumulating on one of the front sensors. That or road grime.

Does anyone else notice this noise when in 4 cyl or less than 8 cyl mode? Wondering if it is due to the flapper or flappers. Edit: Not my truck, found this on another thread, but sounds just like mine.

Is this the exhaust leak type sound you are hearing?

Unseen issues will continue to exist no matter how thorough an inspection but uneven body panels and out of alignment beds should not. Especially at 60-70K. I don't think that is a lot to ask for with any manufacturer.

TSB regarding vertical alignment is here in case anyone needs it. https://static.nhtsa.gov/odi/tsbs/2020/MC-10181703-9999.pdf

Found this TSB regarding bed alignment and it may help some here. I haven't taken it to the service dept yet. https://static.nhtsa.gov/odi/tsbs/2020/MC-10181703-9999.pdf

Yea I have a rattle in that same area. I tried to locate it by putting pressure on different parts of the dash with no luck. It changes with different temps as some days there is no rattle at all.

Yea regarding up and down mine is really close on the passenger side but off quite a bit on the drivers side as well. When I had the TSB done to correct the left to right, the I noticed the bed is now centered but it is not quite as wide as the cab overall.
