Bringing this back to the top. Thank you so much for all the information. Yesterday I tapped 23 and installed footwell lights and they work brilliantly. Once the weather cools off a bit (90's yesterday), I'll get them installed for the back seat.

If this is a 2021 it is extremely likely you need a firmware update on the infotainment system; I have the same issue and waiting on the dealer to get my truck in for this an address a couple small issues from time of delivery.

2021 RST, I've had a bit over a week. Had this issue crop up once, so far. I will have dealer update infotainment firmware for possible unrelated issue.

I've had my truck for roughly 10 days and found this issue early on. I will have it resolved when they replace my passenger side mirror since it was damaged prior to delivery.

I've had my truck just over a week and noticed anytime I hit "apps" on the display it brought up a connection error and said to check my internet connection. I work in IT, specifically networking and I tried all the typical stuff; connect truck to home wifi, have truck forget home network, turn off wifi on phone, power phone off completely, - all resulted in the same error. After I did everything I could I contacted On*Star who put me through to the connection troubleshooting folks. There was a module change between 2020/2021 involving wifi resulting in the infotainment system not communicating with the Wifi module of the truck. I have thought they were all bound by hardware but, from what they told me, wifi is separate from Infotainment system and they only communicate wirelessly. The fix is a firmware update which can only be applied by the dealer service dept. Likely because the system cannot communicate via wifi and thus cannot download update. So, if pressing apps on your display results in a message stating to check your internet connection then the dealer must update firmware. I have yet to have this done, hopefully will be completed within the next 10 days. If so I will update here. Hope this helps.

I tried messaging the OP about the bass cut method he used on the door speakers; I find them terribly annoying and fear the doors will rattle soon enough if I do nothing about it. How satisfied are you with the solution? Did you make additional changes later?
