Yes, happened to me a couple of months ago. I got a recall notice in the mail but it didn't say what for. I tried on mygmlink and it wouldn't work. I finally called the dealership to find out it was a PCM upgrade for E-85 fuel tables. I don't run E-85 so I don't care...

I called them Friday night and they called me back 1 hour later and told me to check it and it showed up as registered then. That's very fast. They had to call dealer to verify purchase as title was still in dealers name.
