2016 Silverado High Country. 
Radio has been working great for years with no problems (SiriusXM). Turned the truck on today and nothing is working regarding SiriusXM however all other forms of radio or audio work. Im in a city and have never had XM issues before. Not sure what to do and haven't seen any recent forums with a good answer. Thanks in advance for any help or tips.

Welcome to the site.

 

Log into your XM account and send a refresh signal to the truck.

is it not working in a certain area, or is it dead everywhere ?

Dead everywhere, it was working just fine the day before, I have very few if any dead zones around where I live for an example. And it won’t let me reply for some reason to the other comment but I have exhausted all efforts through SXM help that’s why i came here. 
Thanks!

2nd guess:

 

With what you have described here this is either due to a fault with the antennae itself ( even if it looks o.k. the antennae itself can fail internally ) or the XM radio receiver. Both will cause this fault here as I have seen before.

What has to be done is to have the fault codes checked/read out of the radio and XM control unit using a compatible scan tool/computer that will plug into your vehicles data port that can communicate with all computers in your model. There will be at least one fault code set with this issue here that will help to diagnose and locate this fault. This has to be done with a fully compatible scan tool/computer that can read all the computers in your model.

I would say most common for this issue that I have seen is the XM receiver itself as these tend to fail and require replacement usually by a dealer as the old receiver has to be deactivated by the dealer and the new receiver activate in your model for it to work.

Appreciate all of that info and advice, I’ll get that checked asap. Thanks again!

Same issue for me! I’ve used Sirius xm before and all was fine then one day blocked signal. I’ve tried refreshing and spent multiple calls with Sirius and nothing has worked. They want to charge me $400 to replace my antenna.

The satellite antenna is separate but within the same shark fin on the roof. The seal at the bottom has been known to not drain water and flood the internals causing them to corrode and fail. Buy a new antenna with seal and replace.

      Because that is IDIOTIC, much like this question. They've already been forced to do it by past administrations - why would you roll that back when it's a GOOD thing?  WHO IS ARGUING FOR LOWER MILEAGE???? 😂  NOBODY IS!!   I'm certainly not! What I want is RELIABLE vehicles again that are worth the price paid!    I don't get your logic here ...   In 2003 I paid $2,200 for our '86 Grand Marquis. It's STILL running and I've never been inside the engine, aside for the timing cover since it was leaking, so I threw a new timing set in since that makes sense. Transmission is ORIGINAL. Electric pump in the gas tank is ORIGINAL. Rear end is ORIGINAL. I'd have to hit my head REAL hard to want to pay $60k or more for a car that still can't come close to the comfort, seating and storage space, or reliability of this one. Nothing is even in the ball park! Hundreds of thousands of brands and models have been built and sent to the crusher while this one keeps on going!   https://postimg.cc/Z9XRrCSg   I've got a whole fleet of cars, motorcycles, and a truck close to this age for summer and winter. No one could pay me enough to buy anything built this century. I have zero use for any it.

      Since I'm the one who has to fix them when they break, I'll take vehicles over 30 years old all day, EVERY day, over ANY modern crap. Have you attempted any repairs on anything built after 2006? It's a friggin nightmare, and gets worse the newer the model year.    If I had the will or desire, I can make any car of any age outside of a Model T (I don't have THAT much will ...) just as powerful, comfortable, and have all the tech the new stuff does, and get pretty close in mileage, too. I prefer SIMPLICITY. The less the vehicle has, the less to fix WHEN it breaks, not IF.   I'm glad you snot-nosed punks don't like them. More for us, plus that keeps the prices from climbing more than they already have.👍

      Bringing this thread back on topic. I just noticed the incredible lack of bright chrome across the entire new lineup. Even the Denali has tinted the brightwork in the grille and has none elsewhere. None of them have chrome bumpers. As far as I can tell there aren't even chrome mirror caps. I'm curious if this also happens out back? Are there no chrome rear bumpers either? This is quite the departure for GMC.
