BCM issues
many, many folks are having electrical issues, especially w/ 2007 tahoe. most say it's the bcm. probably so, and it drains the battery. but nobody speaks directly to the issue w/ answers. please someone.....you have to have experience w/ this.

I had a drain on my battery on an 07 suburban. I would leave the hazards on for 10 mins and it died. They reprogrammed the computer and never another problem. It was a fairly common problem iirc. If you have anything extra wired to the car, I was told the bcm could be affected.
