I'll join the club. I notice it mainly during light throttle. It stops if i accelerate faster or let off the pedal. I've only driven it in 2wd. Maybe it's when cylinders are deactivating? Sent from my SM-G892A using Tapatalk

Mine does it, a very high pitch noise for probably 20 seconds or so. It does it regardless if i set the parking brake or not. It is also a different noise than when i unlock and open the doors. Sent from my SM-G892A using Tapatalk

I didn't pay for the hotspot so i connected mine to my home wifi for software updates. I'm not sure how long it connects each time. You can check by going into the wifi options. Sent from my SM-G892A using Tapatalk

I also have a rattle from the rear headrest depending on temperature. If i drop them forward, the noise stops. Sent from my SM-G892A using Tapatalk

I use fuelly.com to log fuel mileage and see what others are getting. You don't have to sign up if you don't want to, just scroll to the bottom of the page and click, browse vehicles. There are some 2019s listed already including a Trail Boss.

The GMC's look a little different.

Nice!

I got all the windows tinted! I also got Llumar Air 80 on the front windshield. It is clear and reduces heat by almost half and blocks 99% UV. No effect on HUD or auto lights.

The airbags may deploy differently depending if the computer reads whether the seatbelts are fastened or not. The issue maybe if you pull the clip so it reads you are wearing your seatbelt during an accident when you are not. I know of a specific example when the clip was disconnected and the airbags still deployed in an accident.

Finally arrived! Pacific Blue Sierra

My Sierra just arrived today in Texas. It was invoiced and received a VIN on 09/10/18 so it only took 2 and a half weeks. The dealer did claim they put a rush on it?

My truck just arrived today. It received a VIN on 09/10/18. That was only 2 and half weeks from production to delivery in Texas. The dealer claims they put a rush on it so maybe that is why it didn't take a month.

Doug, How long from when your truck got a VIN until it arrived? I got a VIN on 09/10 but GM keeps telling me it is code 4300 in Ft. Wayne, hasn't been shipped, and no ETA. Good looking truck by the way!

I'm still waiting on my 2019 so I can't say for sure... but on the past trucks, there is a wire that comes from the bottom of the buckle between the seat and console. Follow it a short distance to a small connector. Unplug that connector and it will read that the seat belt is buckled.

Someone may have a better solution but this is what I did. There is a wiring panel to the left of the brake pedal with a black cover. I put a crimp connector on a wire and connected it to a stub in there. I then wired it to a relay so it does not draw power directly from the stub. The stub I used provides power when the key is in the on position only, not accessory. I included a picture showing which stub I used. It may be safe to pull power directly from it but I wanted to play it safe. When I add the picture, it is sideways. The bottom of the wiring panel is the right side of the picture.
