It is GM's fault when they do not proactively manage their supply chains. It's GM's fault when they use incoming parts to build new trucks rather than use those parts to repair existing trucks. It's GM's fault when they totally mismanage the reliability and durability of their trucks. I suggest selling whatever GM stock you may have because the recent fiascos are going to cause buyer blow-back and reduced future sales which will drag down stock price.

Running AC is normal to dehumidify people, clothes, etc and keep window fogging to a minimum.

And right you are Sir! Good explanation. Thanks!

I agree the cause is most likely vandalism. Time to talk to your insurance agent about filing a claim (i would assume under your comprehensive fire & theft coverage).

So Nathan I'm curious what Pam at Robideaux Motors told you to expect for delivery time on your factory order. Availability of Sierra & Silverado HDs continues to be poor because of microchip supply issues, especially for top end Denalis that require more chips than lower trim models.

So Nathan tell me what Pam told you to expect for delivery time on your '22 Yukon factory order?

Whoops I see that the "other dealership" identified a root cause and has agreed to process a warranty claim. Winning! You might think about how snow-plowing when in 4WD could be a possible contributing factor for transfer case bearing and u-joint failures.

The fracture surfaces of the yoke need to be examined microscopically with good illumination to assess if the failure was caused by fatigue crack growth to final fracture (when the yoke was being heavily loaded as you "walked out from the shoulder"). Think of it this way; if a significant portion of the yoke cross-section was cracked by a growing fatigue crack, the yoke when heavily loaded may not be able to withstand the loading stresses and then can "catastrophically fail" to complete fracture into two or more pieces. If the fracture was caused by fatigue there will be tell-tale characteristics that indicate fatigue and where the crack initiated and how far it grew until the final fracture event. Crack initiation sites for fatigue crack development are typically associated with surface defects such as a deep scratch or gouge or maybe a forging or casting defect. Examination by someone with extensive experience repairing broken equipment may be fruitful. If the fatigue crack initiation site can be traced to an as-delivered defect, it may provide a good argument in support of a warranty claim. For clarity do understand that for common failure analysis of fractures the following terminology and defintion is used by failure analysts. To wit, a part is cracked before it fractures completely into two or more pieces. Try to avoid piecing the two halves of the fractured yoke back together as mechanical rubbing damage between the two fracture surfaces will obliterate fracture details. That can make interpretation of the fracture cause more difficult and less definitive. If you can take well-illuminated pictures of the yoke and fracture surfaces, it may be possible to give you a remote assessment of the failure cause. However, in spite of all that, I agree with mrjulian416 that an insurance claim for damages sustained by sliding off the road will probably be the best route to take to cover your damage costs. Unless there is clear indication of a yoke manufacturing defect as root cause for the fracture, GM will (rightfully) refuse a warranty claim. Go get 'em and good luck!

animal41 -- I feel your pain. I ordered a full-up Sierra Denali CCSB 4WD 3500HD back in April. The order was rolled to a 2022 in July and built Aug 17 whereupon it went into "Chip-Hold" on some parking lot in Flint. Dealer has been less than helpful updating status. But in the last few days it appears that the truck has been "chipped" and shipped. Dealer still has not obtained an actual delivery estimate. FFS! I suggest deep breathing and meditation!

Doh! Homer face plant. Obviously go to Chevy inventory listing.

Review GMC inventory for trucks configured like what you've ordered. If the truck was built Wednesday it will soon hit the GMC inventory. The window sticker will be available to print. Good luck. My 2022 Cayenne Red Denali SBCC 3500HD was built back in August and is apparently still sitting on a parking lot in Flint, MI on "chip hold" awaiting chip modules to complete the build and ship. I do however have the sticker confirming the truck has what I ordered (less heated rear seats).

Mike-cubed -- A google search turned up Tirechain.com. Lots of good information and a very wide range of products. Prices seem high but OTOH I haven't bought tire chains in several decades with the advent of AWD. I did note they sell cable chains for LT tires. As for the caution above that new diesels will destroy "normal truck" chains, I suppose so if one is stupid enough to apply excessive accelerator inputs.

Mike-cubed, Good search and information. Get a cheap set of chains with packaging that indicates they fit your rear tire size and you're golden. I recall that Les Schwab Tires in the past will buy back unused chains for your original purchase price at the end of snow season. Or if you believe you will actually need to use chains such as for a freezing rain/ice storm event, see if cable chains are available. It seems likely (to me at anyrate) that cable chains will fit rear wheels without interference. Let us know how you decide to go.

Are you referring to the signs posted on WA mountain passes that state something like this: "Vehicles over 10,000 GVWR must carry chains at all times"? This sign is directed at large cargo trucks... think semi-tractor/trailers. Furthermore if you have 4WD and M&S rated tires you never have to use chains. I suggest you search the WA DOT website for official information and regulations.

The window sticker is available for each vehicle shown on the GMC inventory listing. THe sticker for my factory order is absolutely consistent with what I ordered less heated rear seats which has been deleted by GMC (presumably to save a few chips per vehicle). There is a $200 credit on the MSRP for the deleted rear seat heat. And the standard equipment listing on my MSRP unequivocally includes Front & Rear Park Assist.

All those trucks outside the Flint plant are probably on "chip-hold" waiting for chip modules to be received and installed at which time the particular lucky truck will be loaded onto transport for delivery. I have a 2022 cayenne red 3500 Denali HD with Denali Ultimate option that has been held since manufacturing completion (less certain chip modules, of course) on 17 August. My original order was placed 7 April for the same as a 2021. So tired of waiting.

Only if you are a conservative! It is afterall the "People's Republic of California" !
