Sorry, have not had any issues with my iPhone 13 or Apple CarPlay at all. Ready to roll as soon as I start the vehicle, and works great for the duration of my drive.

Thank you for the info. I was hoping it would magically disappear with a few engine cycles, and it did not today. Guess I'll run it in to the dealer soon and see what gives.

So, I had an engine light stay on when I started the truck after work today, got 1100 miles on the truck. Got the info below via email from onstar after they investigated. Just curious if anyone else had had this happen, and what/how long at the dealer? Thanks for any prior diagnosis/timeline. ECM - Engine System P11D5 The Emissions System is not performing as expected. An issue has been detected in the Exhaust Emissions System which monitors and controls exhaust gases released into the air from the engine. If the vehicle is continually driven with this light on, the emission controls might not work as well, the vehicle fuel economy might not be as good, the engine might not run as smoothly and could lead to future repairs. Service within 7 days

Me too! I remembered this comment when I took delivery of my truck a month or so ago, had 4 miles on it. Pushed the brake peddle to start, and it almost went to the floor. Followed these steps then, and has been fine since.

Looks great, congrats!!

Thank you, (and all) I was wondering if tire wear would be an issue. I'll just follow the inflation sticker. Not looking for premature tire replacement, that's for sure.

Hey all, I have always followed the tire pressure sticker on the door jamb when airing up, but the stated pressure seems excessive (60 front/70 rear) for cruising around with an empty truck? This is my first 2500HD, so not sure... I've got stock 20" Goodyear Wrangler Trail Runner LT275/65R20 What are you guys airing up to with this tire? Thanks for any input. M

Ended up getting 60k for the AT4 on trade.

Sounds promising, my VIN sticker states my truck build date was 10/21 and I drove it home from the dealer on 11/4. What did you order?

You are correct, my new truck is very quiet while cruising down the highway.

Those came from Chevy with the midnight or trail boss package as I recall. Too long and a couple trucks ago to remember exactly, sorry!

It is easy to do, select settings from the Home Screen, system, then wifi networks. Good for any updates if you do not have the wifi hotspot data plan.

Nice truck, enjoy it! BTW, just did the same thing AT4 to 2500 LTZ, need more capability as well.

So I shifted gears, requested my hold deposit back for the high country and instead bought a 2022 2500HD LTZ in white. It has all the options the high country and had the addition of black rims and badges, so happy about that. One less thing to do to it.

Nice truck! Those black wheels would look great on the RST!

That is a nice looking AT4! I was looking at my local dealer at the same thing in white, and they wanted a $10k market adjustment on top of sticker, so I passed, and moved on to a Chevy High Country. Too bad, I really like the AT4 trucks!

Wow, just placed a hold/sold deposit on an inbound 2500HD Silverado High Country with the diesel. Supposed to arrive by the end of the month. Not sure what I'll get for my AT4 till I get up there for an estimate. Hopefully I won't take too much of a beating. Sadly, there is not a 5th wheel hitch available for the carbon pro bed, so an upgrade was needed since I'm going to be looking for one. Have not owned a diesel before, so will be checking the forum for tips. If anyone can recommend any threads from break-in/towing, etc that would be great! Thanks!

Hi All with Carbon Pro bed - - I have been thinking of getting a light weight 5th wheel for my truck, but GM dealer said there is not a suitable hitch available for the bed. Am I outta luck, or has anyone found a good after market hitch? Thanks!

I love my 6.2L of kick @ss American muscle!

I purchased PN 84791287 and had it installed at the dealer. It is a high quality flush mount tonneau.

Just ticked past the 7,500 mark the other day, and the truck is being a very good boy with no issues since day 1.

Thanks guys. I will be waiting for them to do it, and wondered what amount of time I had to plan on.

So I got the Onstar monthly vehicle status check email, and it listed a recall for air intake calibration. Has anyone had this done, and if so, how long did it take the dealer to do it, just curious. Thanks

I can't imagine you being disappointed with the AT4. No complaints here whatsoever. My last Raptor with the 6.2 was a ticking clunker: lifter noise when idling, drive line clunking when coming to a stop, all of which according to the dealer was normal. That kind of stuff drives me nuts!

Nice looking truck, enjoy!!
