Did you take the car to the dealer for their update?
Did the Buick Lady call you back?
Took mine in to the dealer with everything apparently working. The kept it for almost two hours. Of course there is no way to tell what they did, but I did have to pair the phones again. Everything works so far.
The Buick Lady I talked to assured me that this problem was over. Guess we will see
Got a call back from Buick. I asked if I should go to my dealer to follow up on my outage, and the answer indicated that I would not be any better off, as the dealer service dept would not have any additional solutions. She could not verify if any OTA updates had been installed, and the dealer would not know either. I could not get confirmation if I was back to the pre attempted update status, or even what the update was attempting to address. Given that my outage was the same as yours, but happened 2 days ago, unless you were informed of the issue resolution in the last 48 hours, then the problem is most definitely not fixed. As I posted earlier, I was told that GM is aware of the issue, but not the reasons that trigger the problem. Starting the car during an update-in-progress or being in an area without connectivity did not convince me as being the triggers for my outage.
Everything seems fine for now.
