My words to the dealer would have been
If you can't tell me what you're going to do to my car, Don't PHUCKING touch it.
I got an update today 12273 I think was the number could anyone find out what it was. The dealer did not know, but they updated it anyway.
i asked a gm tech and they told me they could not discuss it with me. so any help?
When I talked to my Service Manager on Thursday he told me there was an update. He grabbed a tech to explain since it didn't say what it was for. The tech said it was to fix an issue with not being able to restart the car after a stall.
