Wife's rig is a 09 tahoe. Been having issues with it the last couple weeks. Randomly will be driving down the road, and the navigation/radio turns on and off, and I also believe all accessories inside loose power. Then a couple times after shutting off vehicle, it will have NO power. No door locks, lights, ignition, acts light it has no battery. Then after sitting awhile it randomly has power again. Always has happened when I haven't been around, so have been un able to trace wires. I have checked all connections at battery, main fuse, fuse block, ect. Everything is tight and clean. I'm at a loss with this thing!! Anyone have any experience with the new body style GM's doing this?

Sounds like a faulty ignition switch
That's shouldn't cause vehicle to loose all power tho at times.

-Oh no I picked a side-
Not in an 09. Sounds like a possible communication problem between modules. But you won't know till you check codes and see if there are any U codes.
Guess ill have to get it into the dealership then!

Probably a 12v with positive and negative connections:fawkdancesmiley:

Thanks for the update. If it's a Schwabbie special, WalMart, or some other POS pile of garbage, I've seen issues with voltage loss at the connections cause stuff like this.
Thanks Man. Just seeing this tho!
Its got a AC Delco Battery in it- so it should be a good one.
I know, seems the site went down right after I posted. :haha: If you still need it scanned, I'll be down at the shop sometime tomorrow after 10am.
Edit: Your box is full.
