2007 NBS Silverado Battery Rundown!

  

biglg -> 2007 NBS Silverado Battery Rundown! (5/22/2008 7:30:34 AM)

Anyone have a NBS silverado and has the battery run down issue?  I know my 2007 tahoe had this problem however I havent ready anything about this on my Silverado.  About 2 weeks ago I had the radio on for about 15 minutes one night while drying it off after a bath.  It was dead at that time too.  Almost identical issues to the Tahoe but I have read of a fix, TSB, or recall for the silverado's.

I hadnt driven the truck for about a week and went out to drive it yesterday.  It was 100% dead.  It was so dead that the codes for the garage door opener were messed up.  I jumped it and it started just fine.  However, this is a pain and I am not going to be driving it very often.  Will i need to jump it every time I drive it?

Yeah, I work 24 hr shifts and left my dome lights on and they drained my battery dead, called onstar and they had somebody out in 20 minutes to get me going again, but it is an annoying problem. I thought there was battery rundown protection on the chevys, my 2004 Ford had it on it.

I had that with my 2003.  They had a recall on it and reprogramed the computer to fix it. That was the only time it was ever back to the dealer.  Never had another problem.  No problem with the 07.

BigLG...don't you have a bunch of aftermarket stuff in your truck also? Make sure that stuff is not casing your drain before you condem anything else

shawnvw,
Not sure what aftermarket stuff you are talking about.  The only aftermarket electronic item in the vehicle is a kenwood rear view camera.  However, the way it is wired it is on switched power so that isnt the problem. 

I will be taking it to the dealer as this was a mass issue with the new Tahoes and this problem is almost identical to my 2007 Tahoe issue when they made an update for the computer. 

I just wanted to see if anyone else was having the same issues.

Have you had the BCM reprogrammed?  Just a thought, as that was the problem with my 2007 Tahoe and this corrected the problem.  It would run down when sitting, and I have not had an issue since.  There is a TSB on it, and mine was done in 11/07.  There is so much tied into the systems anymore that run more then we do not expect it that it sure doesn't take long to discharge them.  Hope this helps!

I have the same problem with my battery. I have gone to the dealer 3 times they cant find anything. I have notice if I start the truck around 6 am and let it run for about 10 min. it is fine the whole day. If I start the truck after 8am I have to jump start it.
