What's laughable is that you think they can collect $1200 (or whatever) a vehicle and pay out $3000/vehicle, and cover all the costs of promoting and selling and be in business. Of course some will collect. But most won't. I've been buying new vehicles for more than 40 years. I've had very few failures. None that extended warranty would gave covered.

Not outdated, it's just as true as ever. Those selling extended warranties do so because it makes them extra profit. If they were going behind the price would get cranked up until they are again profitable. If it makes you sleep better -- go ahead an buy one.

It will be in the QR code at the bottom of the drivers doorpost (most smartphone cameras have built-in decoder) I think someone is misleading you. On 2023 Denali Ultimate, the - 3.0 has MCQ - 6.2 has MHS and the NHQ transfer case (the 2 speed one) (8 speed, and column shift version applications also shown for completeness.) Probably hard to read with usage chart so without chart --

Not always just a Gm division thing. Seems it might also depend on year. Might also depend on trim. Might also depend on build date. My 2023 Denali 1500 only has buttons on the front doors. When standing ready to open rear door, I can easily tough the button on front door to unlock. Yes, extra arm motion, but no extra footsteps required. There have been lots of threads about this issue since the buttons started disappearing on some trucks.

Did you reboot the phone during the forget/re-pair process?

2023 Upfitters docs include this info about charging and auto stop/start

Fwiw, the charging system is managed and monitored by computer. It adjusts charging, can turn adjust loads etc etc. This chart indicates what OEM equipment (but doesn't use standard industry coding)

Don't put Dex Vi in your 10 speed.

Thanks for the update

I agree that name brand is likely a good idea -- but for this job I'm using a random freebee I've had for years.

There may have been updates that didn't change the onstar version. There many be updates that require the vehicle to be plugged into dealer computer.

Mine has no audio files in the root. USB hadn't been used in this truck. (usb is old, I've used for years in other vehicles) I didn't even start the truck. Just used acc mode. I only stayed in truck long enough to verify that it would play and didn't wait for index to finish. Once I selected usb as source it said it was indexing, and the audio started playing. I was able to use arrow controls to move between songs while this was going on. I think my 4GB is about 45 hours of audio. Makes 80GB work out to 900 hours...that's a lot of audio!!

What file format are you audio files? My 2023 will work with MP3's. Haven't tried any other file types. Most of my audio was cd's that were converted to mp3's using itunes on a descktop (a few years ago) About 16GB usb formatted with FAT32 About 4GB of data. (mostly audio) Files organized with nested folders. Artist>album>song

What truck / transmission do you have?
