Dbs-than Answer
Just got a REALLY HOT tip from a mechanic about DBS in our 2005, C6, 6-speed Vets. Have you programed your vehicle to activate your home garage opener? Does your garage door have rolling codes? If the answer is YES, this may be the reason our batterires are dieing. The mechanic told me that he has seen this in some Cadillac and '05 Vets. He says that since the door opener has rolling codes, it may be communicating with our Vets even though they are shut down. It takes about two weeks for my battery to die, which the mechanic said is about the right timing for the door opener to drain the battery. I'm going to deactivate my opener RIGHT NOW!! I'll keep all Vet owners posted as to the progess of lack of. Good Luck.

Interesting. Well, to my knowledlge, only the 1SB (3LT) cars come with the garage door opener feature, so this would not explain DBS in the other packages.
Seems that the C6 in general is sensitive to various electronic issues... DBS is probably a function of several or many different things. But the more we know, the better!
Will be interesting to see if your DBS totally goes away once you deactivate the garage door opener. Best of luck!

on the mechanics analysis.The garage (homelink) unit would then NOT be the cause of DBS if the Vette were not in the garage (or proximity).
However, this same issue (DBS) has occurred EVEN when the vehicle is not in the garage (or proximity) for extended lengths of time.
Lastly, why doesn't this same occurance happen in other vehicles? As an example, I have a Durange ('05) that has sat for over 4 weeks in my garage. It has homelink, and the garage doors have rolling codes,
Yesterday I started the Durange - no problems.
Further, the homelink amperage 'draw' is just not sufficient to cause this issue during a two/three week period.

According to some surveys I have seen on this board and others the majority of DBS happens with the MN6. MXO's have garage door openers why don't they have the problem.If it were garage door openers/homelink I would assume it would affect both vehicles equally.

Same here. Mine is one year old, never check the steering wheel lock, and have never experienced DBS. There has to be something more than just the garage door codes going on here.

I highly doubt the mechanic's hot tip!! I have had several cars with the Homelink System and I have rolling codes on my garage door openers. I have never had a problem with them. My new 06 has the Homelink as well.

However, now that you mention it, my daytime office garage opener uses a rolling code, and I stopped using that garage about the same time my DBS's stopped last winter.
Good thought, but doesn't explain lack of DBS in automatics.
Also, I don't recall hearing about any DBS's away from home on this forum. Maybe I missed something?

Your mechanic should stick to mechanics and leave theorizing about electronic stuff to people who understand it.

I've said all along that I think a number of different issues are getting linked under the heading of DBS. For sure we know that some C6s came from the factory with defective batteries. For sure we know some DBS incidents were operator error, ie failure to shift to reverse, leaving the courtsey lights on, etc. Likely there are many other causes too.
It is striking that most of the complaints come from those with the manual transmission. That would tend to indicate a problem in the shift to reverse and/or column lock areas, since the auto cars don't have either one, and don't have many reported cases of DBS. It is also noteworthy that GM has removed both from the 2006 cars. My personal hunch is that most of the failures are related to the column lock failing to engage. Either the solenoid sits there drawing power, or the computers fail to complete shutdown procedures when the lock doesn't engage properly.
