I purchased a 2021 Silverado Z71 in April, and I love it, but an odd quirk with the infotainment system. Each time I get in my truck, with the same cell phone I always carry, I cannot make a voice activated call for up to 5 minutes. The response is always "please wait, I am loading your contacts". Why does the system load my contacts each time I get it the vehicle? Is there any way to have it store the contacts and not upload every time? Is it supposed to do this?
When I set "maximum start-up volume" to a good level, it will hold for a couple of starts. then it reverts to a very loud start-up volume. Radio blasts loudly until we turn it down. Reset maximum start-up volume repeatedly but will not hold. always reverts to loud start up volume. service department has not heard this problem, but a friend with a 2021 silverado has the same problem, exactly.
Looking at getting the 20" Factory Reproduction Style 59 wheels in black and would love to see if anyone has pics of them installed on their trucks.
This is more of a FYI after a bit of runaround with GM/Onstar support.
I'm on the 2nd week with my new '21 Sierra Denali. The issue I'm having is when accessing the "Apps" module in the infotainment system. When I try to open it I'm presented with a connection error asking me to check my network settings, available data, or connect to another WiFi (attached screenshot). After checking everything, connecting to multiple WiFi, etc. I called GM/Onstar support and after being passed around I ended up talking to a support tech that knew exactly what the problems was. This issue isn't related to the vehicle's setup, but apparently related to something that Amazon did with their service(s) that is causing the apps module to fail to load as it checks for status upon loading. This issue started popping up around 2 weeks ago and, according to the tech, affecting '21 Sierras (and later '20s). There is no ETA on resolution to this, but was informed that engineers are aware of the issue has there is an active service ticket for it to be fixed.
Hopefully this post will help out any other owners having the same problem as it's not something that is readily known to GM/Onstar support.
