I am not in Houston, but in the Atlanta area and I am convinced it is the bad buffering antenna that is causing this problem and seems GM and others like Audi have not figured out their receivers that are being installed are garbage. For this kind of money, I should at least be able to receive under an underpass. the receiver doesn't hold a buffer long enough. It's actually real time streaming. Not good for satellite radios.

In almost every vehicle i have had since satellite radios were a thing, it has worked flawlessly. Ever since I bought my 2018 Silverado High Country, the satellite radio reception is garbage. There is absolutely no buffer and as soon as I drive under a bridge or even look at some trees, the signal drops. And when driving on I-20 near a forest, I may not hear a game, any music, or news for a good 3-5 minutes. Streaming through my phone's bluetooth seems to be the only remedy to ensure the signal does not drop. Is this a known issue for GM trucks? Another forum I was on had a few others mention the exact same problem. If GM is aware, has there been a fix? A recall or something to fix the lagging satellite antenna issue? The truck is beautiful but after spending that kind of money on a luxury truck, I would expect the radio signal for satellite stations be much stronger. I would suggest starting with the receiver and install a quality one that can actually hold a buffer long enough to drive under an overpass at a minimum.

Just started reading these posts and realized i can relate. My truck has been experiencing shake and rattle. I had the wheels balanced and aligned and it lasted for a week before the same rattle came back. Took to dealership and it was found that 3 out 4 tires were suddenly out of spec. For 3 days my truck has been in the shop while the ordered tires again failed spec during a road force balance. Someone please explain why GM is sending to the dealers tires out of spec and that the suppliers where they are receiving the new tires are continually out of spec? Wouldn't it be simpler to use a different brand other than Goodyear that continues to have the same issue time and time again?
