I had this happen today started truck while in wal mart with my chevy app. Got into truck started to drive and all of the reported warning lights came on. Of course my brakes where gone to the floor like a old manual system. I had the recall done early Dec. I have started he truck with the app several times since then. I had on star give me the codes drove slowly to the dealer told the service advisor everything that happened she asked a couple of questions and showed her the codes. They had this happen to another customer recently and everything was the same and the codes. She did state that GM is aware of this issue and is "working on it".
They said they had fixed the other vehicle by test driving and computer programing and some other stuff wasn't paying a lot of attention since I had read about this on this forum.
I was just glad she knew about it and admitted GM knows about it. I am in a Colorado for now they only had this one 4wd vehicle left on the lot and it was just turned in.
Thanks
