According to them, GM does not warrant tire balance. They people at the dealer aren't being assholes about it but I will drop it right back off if it isn't fixed.

Add me to the list of owners of a $50K vibrator. My 2015 High Country started vibrating at around 70MPH when it hit 9000 miles. I'm at 14K miles now and it is getting worse so I dropped it off yesterday. Received a call today saying the tech had confirmed the vibration exists and that the first step is a force balance at a cost of $230. I told them to go ahead and do it. The next step will be to look at the tires if this doesn't fix the issue. What is really strange is that it doesn't always happen. I can be driving into work vibrating away at 70MPH, hit some traffic and slow down, get back up to speed and experience no vibration.
