All warning

[Saltville59]

I have a 2007 Yukon. While driving the radio would go black and all warning lights would come on. It continued to drive and operate. Then one day it would not start, it did absolutely nothing. I had it towed to the dealer. They have had it for 2 weeks and cannot figure out a fix. Has anyone had a similar experience and know a fix?

Could be a number of things, the most likely culprits are the battery, battery cables and grounds, the Body Control Module or BCM. They should have a Tech-2 to put on this and run some tests, not sure why it's taken them 2 weeks other than it sat in the parking lot for 13 days.

Two weeks and no diagnosis from a dealer shop? They’re playing you trying to sell you a vehicle and steal yours.

IMO.

Pics of the truck, please.

As folks have stated above, a competent dealer should have diagnosed the cause of the issue by now. Something is wrong here.
