I had the exact same issue on my '22 AT4x right after delivery. The rear seatbacks have a metal bar that a spring loaded latch grabs onto to hold the seatback in place. There is apparently a plastic sleeve that is supposed to go over the metal bar that keeps it from rattling. The tech that fixed my truck found the sleeve in the floor of the truck.

The speed limit sign are very inconsistent. I have a data plan on my GMC, so it isn't an issues of not having the data. Sometimes I will drive for 20 minutes or more before the speed limit sign starts showing any data. Otherwise, I miss the lock/unlock button on the rear doors as well as the footwell lighting my 2022 Tahoe had.

One thing I don't understand about the programming on the trucks is why the interior lights and puddles lights don't come on as you walk up. My 2022 Tahoe Z71 would turn on the interior lights as I got close to the vehicle (not the puddles lights unfortunately) before I unloacked it, but my '22 AT4X does not. I'm also missing the footwell lighting and the glovebox light that was mounted to the lid instead of lower in the glovebox. The Tahoe also had a small sliding door to the right of the center stack for sunglasses as well as an unlock button for the rear doors. I like my new truck, but it feels like there were a number of corners cut considering the $80k asking price.

Last week I picked up my AT4X that has been on order for months. Today, I noticed that the piece of padding and gloss black trim that juts out below the infotainment screen and above the climate controls flexes a lot when you push on it on the end closest to the driver. I didn’t see anything lose, but the amount of flex makes me think a mounting point is either loose or broken. Has anyone else noticed this issue?

There is a Youtube video that shows how to do it. The video is about fixing the dash rattle common in these trucks. Basically, you remove the A pillar trim on both sides of the truck and then the top dash trim piece pries out. There are push clips across the front edge of the trim piece that you pop out and then you just lift the trim up and away from the window. The speaker grills are part of the trim panel, and you will need to twist and remove light sensor in the middle. I hope that helps.
