I too have had this problem for the last 4 years. I also kept going to the dealer and getting blown off. I finally just bought a spare battery and keep it and a set of jumper cables in the trunk. This way I dont get caught off guard. On the other hand, I watch the volt meter and if it starts to register higher than 14.5 V, I clip a small charger to two wires I have attached to the + and - terminals of the battery ( being sure to keep them separated !!!! ) and let the batttery charge over night. This seems to control the problem. You might also be sure that there is not a CD in the player. I have a hunch that that continues to spin even when the key is off. Otherwise, its a new Acura for me the next time !!!

Also have a DTS with a battery draining in about 24 hours. Dealer (Sadlon) up here in Barrie figured it was the alternator $1400 bucks later nothing changed. Went back had it all tested for the 2nd time they couldn't find a thing and said the battery was good. Sent me on my way. Went to CTC'S corp who said that the DTS was a notorious GM product with a lousy wiring harness. Saw the reference to the TSB #1906368 and called the service manager at Sadlon who said there was no such thing ... Maybe in the US .. But not Canada ... Called GM Canada in Oshawa .. No clue there either. After $70,loo bucks in Canada nada and GM wants it this way. Anyone in the US who can tell me what the TSB essentially says.
By the way CTC'S answer for the DTS was like most of the other solutions for this DTS buy a battery buddy and a portable battery .... Best $100 bucks ... Car is off warranty so so much for the local Caddy dealership ... Back to Chrysler for another 300 ......

I was glad to find out Im not the only one dealing with the frustration of having my battery go dead on my 2006 DTS. It happened twice last year so I put in a new battery 8 months ago. Everything was fine and it then it went dead again last month. Jumped battery and was told everything looked ok. Then it happened again today - always seems to happen when the car has not been driven for a day or two. This time the mechanic will replace the battery tomorrow and do a draw test. As it seems to be an intermittent problem, Cadillac said the issue might not been seen during the draw test. I will refer them to TSP 1906368 as well as advise them to check for a possible poor ground from negative side f the battery as well as all other suggestions I read here today. I printed out this info to bring with me. Thanks to all.

Didn't find anything like the # you posted, but I did find these TWO TSB:
 
TECHNICAL
 
Bulletin No.: 09-08-50-017B
 
Date: February 11, 2010
 
Subject: No Crank, No Start, Discharged or Low Battery (Reprogram Rear Heated Seat Module)
 
Models:
2006-2010 Cadillac DTS
Built Prior to February 2, 2010
2007-2010 Cadillac Escalade, Escalade ESV
2007-2010 Chevrolet Suburban, Tahoe
2007-2010 GMC Yukon, Yukon XL
Built Prior to November 30, 2009
All Equipped with Rear Heated Seat RPO KA6
Supercede:
This bulletin is being revised to add build breakpoint dates. Please discard Corporate Bulletin Number 09-08-50-017A (Section 08 - Body and Accessories).
Condition
 
Some customers may comment about a no crank/no start condition or a discharged or low battery.
 
Note
This condition may be intermittent, therefore it is important to check if a revised calibration has been released on TIS2WEB for this concern, even if the condition cannot be duplicated at the dealer.
Cause
 
This condition may be caused by the rear heated seat module (RHSM) discharging the battery by keeping the serial data bus active, which creates a cumulative continuous draw of four amps on the battery after the vehicle is shut down, until the state of charge reaches three volts.
 
Correction
 
Important
DO NOT replace the RHSM or the battery for this concern.
Reprogram the RHSM with the latest software calibration.
 
Important
Select the correct calibration files for the appropriate vehicle configuration (body style) and RPO codes.
A revised calibration has been developed to address this condition. Technicians are to reprogram the RHSM using the Service Programming System (SPS) with the latest software available on TIS2WEB. Refer to the Service Programming System (SPS) procedures in SI.
 
When using a Tech 2(R) or a Multiple Diagnostic Interface (MDI) for reprogramming, ensure that it is updated with the latest software version.
 
During programming, the battery voltage must be maintained within the proper range of 12-15 volts. Only use the approved Midtronics(R) PSC 550 Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent during programming.
 
--------------------------------------------------------------------------------- -
 
Bulletin No.: 06-06-03-009
 
Date: October 19, 2006
 
INFORMATION
 
Subject:
Diagnostic Information on Battery Draw No Start - Body Control Module, BCM Power Timer
Models:
2006-2007 Buick Lucerne
2006-2007 Cadillac DTS
2006-2007 Chevrolet Impala, Monte Carlo
2007 Cadillac Escalade, Escalade ESV, Escalade EXT, SRX
2007 Chevrolet Avalanche, Equinox, Tahoe, Silverado, Suburban
2007 GMC Sierra, Yukon, Yukon XL, Denali, Denali XL
2007 Pontiac Torrent
When performing normal diagnosis on a battery that has gone dead overnight, a technician may notice that the vehicle has approximately 4.1 amp draw on the system. The draw may be steady or may drop down to a low milliamp reading for 1-2 seconds and then rise back up to the 4.1 amp range. If this amp draw condition is observed, check for aftermarket accessories or an improperly installed GM accessory that is wired into circuit 6815 (orange wire) for courtesy lamps. Anytime aftermarket accessories are installed into the courtesy lamp circuit, it can cause the inadvertent power timer in the body control module (BCM) to keep resetting. The BCM will remain awake and cause the draw of approximately 4.1 amps.
 
When servicing a vehicle with this concern, back out pin 1 of the connector 2 at the BCM and see if the draw goes away. If the draw goes away, check for an aftermarket accessory (Lojack, non-factory DVD system, alarm, etc.) that is improperly installed in circuit 6815.

For the first time since I purchased my 06 DTS in Jan. 06, I went out to the garage on Monday to leave and was surprised that there was absolutely no power to start the vehicle. I called for jump start service and it started right up indicating that the battery had totally discharged overnight. I had the battery replaced about a year ago since that was due so that should not be the problem. Dealer ran all their tests and said there was not anything wrong battery or electrical system wise. Now that scares me. My main reason for this email is that I likewise purchased a portable battery to put in my trunk should it be needed. Then, my brain started working and I realized that without power, I cannot open the trunk to get to the portable battery. I guess that I will have to put it on the floor of the back seat area. I also noticed that someone had indicated that you could not unlock the door without power and if that being the case, I still could not get to the portable battery pac, nor, could I get to the hood release so I could get a jump start from another source. And GM just sticks their nose up in the air? Where does one go from here?

I would first test the charging system. Also I would not rely on the car's alternator to charge up that dead battery---that makes the alternator work very hard indeed It should be tested and charged. Batteries do fail, even when they are nearly new, and jump-starting a totally dead battery is not a great idea. I know, sometimes it's necessary, but if you could have a charger in the garage, that's a lot better idea.
 
If the charging system checks out, and the battery is load-tested and found good, then you have a parasitic drain of some kind, and the dealer just blew it.
