#40 of 252 Re: 2004 Chevy Suburban battery drained to zero [richard7564]
Dec 24, 2011 (4:35 pm)
I went thru 3 battery's in 1 1/2 yrs. tested all the fuses to see where the drain was coming from. found some wires under drivers seat that had gotten drug into the track and chewed up the outer casing. so we loosely ties up those so it could not happen again. but after months another dead battery. I had 3 battery shops looking into it. and another 4 mechanics trying to help. but it came down to a girl at auto zone who figured it all out!!! she told me to replace the bolts of the battery. they are made of pot metal and guys get all macho tightening them down and they can strip. I told her come to think of it there were several times that my cables were loose! and because it is a side mount battery they can vibrate themselves loose! have not had a problem since!!!!
#41 of 252 07 Tahoe - EXACT SAME ISSUE AS POST #26
Jan 04, 2012 (8:40 pm)
2007 Tahoe LT-3 w/ 59000 miles -- Truck ran fine for two weeks after purchase. 5 days ago, slow start... 4 days ago, NO start. ACTED like a Dead Battery, BUT lights, radio, etc. still working!! When jumped off, all a/c controls (pass & aux) come on and sometimes Park Assist is turned off or get a TPMS Service notification. Have had same recurring issue and had to jump start Tahoe every morning and everyafternoon when leaving work. No aftermarket ANYTHING installed - just factory Rear Entertainment System (no NAV either). Don't even have a phone charger plugged in!!
Took to parts store for load testing --Battery:OK, ALT:OK, -- took to trusted mechanic for diagnosis....
Mechanic tells me: When you start the truck, all "modules" come to life. When you shut truck down, all "modules" have a rest period before going into hybernation. Mechanic says that one (or more) of my modules is NOT hybernating, and since they require a 12 volt power source this is my battery drain. OBD-II diagnostics revealed a GMLAN code -- something about HIGH SPEED BUS CIRCUIT??
I have read multiple posts concerning this issue we are all having. Here is a compilation of fixes that other consumers have managed to squeeze out of dealers:
1) Service Update #07007B where the BCM (Body Control Module) needs to be replaced;
2) Technical Service Bulletin (TSB) 06162 which is a software update to the Body Control Module (BCM);
3) HIGH SPEED BUS BAR overheats which simulates a dead battery (this info came from a bulletin dated April 2009, but I dont remember were i found it posted)
4) Someone posted that Service Update #07007 is actually a RECALL pertaining to certain VIN#'s. I attempted to verify, but site that was linked to this information is no longer up (go Figure, right??)
HERE IS THE MOST RECENT BULLETIN I HAVE FOUND......
5) Bulletin #09-08-50-017B - Dated Feb 11, 2010
Its the rear seat heater. It does NOT to be replaced, just reprogrammed using an SPS System w/ latest software update. Applies to Escalade, Tahoe, Suburban, Yukon, Yukon XL manufactured prior to November 30, 2009. ALL affected vehicles equipped with Rear Heated Seat RPO KA6.
GM has to know what the issue is here... I just want to fix the problem, NOT sell the truck. If anyone has additional info, or has been able to resolve the issue -- PLEASE post a response !!!!!!! Feel free to email me and I will forward the long version of everything I have.

#47 of 252 2007 Tahoe battery drain issue
Dec 17, 2006 (6:19 pm)
My 2007 Tahoe has drained the battery twice when sitting with the engine off, key in accessory position and the DVD playing. The first time was after 30-40 minutes. Today it happened at a drive in restaurant after no more than 15 minutes. The tow truck driver told me he had the exact same call the day before. Is anyone experiencing this problem?

We have a '07 Suburban and have had the battery drain twice and had to jump start it. I was trying to decide if we had a marginal battery or what. One time the kids were watching a DVD in the driveway, another time I was parked on the side of the road with the flashers on. Next time I'm in the dealer I'll have them check the battery. Are you going to have it checked out? We have the Nav-radio set-up, not sure if that means anything...
#49 of 252 Battery gone dead

Hi Gregg, I sure hope you call GM open case number with them and then call B.B. Do not let your dealership know what your doing I have a friend that works for another dealership who is a service writer.
He said once they know your going to lemon the suv out that they will change the invoice on the repair order. I'm trying to Lemon this Tahoe out, I have not tried used my dvd since this my battery went dead a few months ago.
Its ashame because every weekend I going snowboarding and my kids want to watch a movie, but afraid that my battery will go dead there is no Chevrolet dealership there to fix my Tahoe.
