I think there is something wrong with your antenna or the wiring that connects to it. I think the antenna is in the shark fin, and working in there would require minimal "tearing into things." Maybe start there and see what you find.
2017 Any way to fix awful XM reception?
I saw an old thread or two about this but I thought I'd start this one because I'm thinking of dropping the headliner and getting to the XM antenna to see if there's anything I can do to boost the signal. Has anyone tried anything?
I live in the country and didn't really pay much attention because the only place it went out was along a ~1 mile stretch where there are high power lines on the side of the road. But... I've been doing more driving down in the city this week and just about every city road that has power lines on one or both sides causes the XM radio to lose signal. It's so bad that either I'm going to stop using XM or I have to fix it somehow. None of my prior cars had this problem in the same places.
So I guess I'll start by asking, has anyone tackled this problem and gotten any results? Of course, the car is under warranty (2017) but from the older threads it doesn't seem like much relief is to be had by taking it to the dealer. I'm hesitant to do that anyway because it makes me cringe thinking about the dealer tearing into things.
Thanks,
Mike

Just as a data point, I get virtually perfect reception on all XM channels except when I drive into a parking garage, and 2 other specific spots: one is under a rail road overpass, and one is as I pass through a somewhat deep stream valley with heavy tree cover overhead. It will drop out for ~1 second at those spots. Otherwise it is solid.
That is why it seems likely you have a disconnected antenna wire terminal, broken antenna or antenna wire, interference, or some similar kind of problem that is affecting your reception.
This is probably true, although I once had a vent problem on a Honda. The tech checked another car and said they all do that. I said, yeah, I know... they are all broken (and proved it). He fixed it under warranty. And he even had to drill a hole and add a screw that was never designed into the car.If every Volt radio on the lot performs as poorly as yours, you are SOL. If not, you have a case.
