Then the new battery isn't any good or the cables are corroded or loose.
If you had a bad alternator, even a jump start wouldn't have gotten you going very far.
Maybe he didn't charge the battery properly prior to selling it to you.
I took vehicle home all fine for about 30 miles running around town. Park in drive way on 10 degree slop and came back in the morning turned key and nothing happened same as before. Tried several starts within an hour after--nothing. Tow truck arrived again and this time driver tried starting the car--and it started!! Not consistent. Took vehicle to dealer and all the bad codes are back again (cleared on the first repair) and they are stumped because the vehicle starts and they cannot duplicate the problem. Any suggestions...............
Through the lawyer, Mom found an excellent independent mechanic, Gili's Automotive, Rockville, MD. Gil did a complete diagnostic workup, including checking out the Onstar program. He said there were "several" computer updates from the manufacturer that had not been downloaded by the dealer. There were also some problems with the electrical system not being grounded correctly. Needless to say, Gili's fixed the problem - she has not had any problems since. She also takes the car to Gili's for regular maintenance as the cadillac dealer is totally unreliable.

Apprently they listened and looked harder and found under the steering wheel lower dash a wire had its insulation rubbed through and was grounding. Apparently the wires are not routed correctly causing rubbing. Apparently Cadillac DTS 2006 has had prior problems with this (they found out from GM after mine was disagnosed) however there is no TSB at this point. Apparently there should be at this point.
They fixed the problem and now I am happy. I was losing my mind with the intermittent problem. Good luck with your problem.
GOOD LUCK
and many service calls I had to utilize the Lemon Law to get it resolved. The
car has been fine since.
I am trying to install a back up camera system on my 2008 DTS and I need to know what the color code is for the back up lights wires leading into the tail light module. I find a yellow, yellow/white, purple, green, black, and one color that I don't remember right now. I'm trying to find the positive and negative colors for the back up lights. Anyone able to help?
Would appreciate thoughts on my theory.... I am still going to test it further, when I have a chance to let the car sit for a full week... then I'll leave the car unlocked with the battery charger standing by.
As a final note, when I get in the car I hear a very faint wurrring sound, a space, then the sound again.... and it might continue but by then I have started the car. That same sound can be heard when I get in my lady's 2007 Yukon. She makes a habit of locking her car every time she is out of it. Her battery is 4.5 years old with no sign of weakening.
I usually leave the car unlocked in the Garage, from now on follow your advice and plan to lock it.
Have you found anymore on this issue since your Feb. 13, 2011 post? Thanks.

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 ......

Built Prior to February 2, 2010
2007-2010 Cadillac Escalade, Escalade ESV

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.

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.
Is your mechanic with one of our GM Dealerships? If so, let us know as we're available to follow up with your service department if you like.

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.
