[HUMMERICH23]

Well I got my Truck back last Friday and so far everything has been ok and they ended up doing 4 updates to all the computers including the PCM, TCM, BCM, and OnStar. They think it was a combo of one of those so they just reset and updated all of them. GM engineering gave them all the updates and besides crossing fingers to see if it works (including dealer and GM) they couldn?t figure it out.

I think it was OnStar even though they said it already had the latest update and equipment .They said my drain was around 300 milliamps but bounced from 250-400 but most of the time it was around 300.

So far she has been great and no problems and the only thing I have noticed which I have always noticed is the volt gauge bouncing between 12-15 volts on me all the time. I read in the book it says it drops lowering during Fuel Economy Mode (whatever the hell that means, shocked to read fuel economy and hummer in same sentence). One service tech thought that was strange thinking it should stay at 14 and the manager said that is normal. What?s your guys? do???
