#75 of 96 DTS battery drain... I think I have a solution
Feb 12, 2011 (10:06 pm)
Bought my 2006 DTS last fall. It is my road car, not used around my mountain village, just on trips "off the hill" of some miles. The car sits for days and sometimes, weeks at a time. I have high security and routinely just get out of my cars and leave the keys in them. On the cars I don't use but a few times a year (Silverado and Corvette) I maintain batteries with Harbor Freight battery tenders... work great.... But back to the DTS.... my battery has been going dead and I've done all the regular trouble shooting, including reading the forum. My mechanic did the ground scraping and such and it still went dead. I have put a new battery in the car, even though a few weeks before the old battery was indicating an ok condition after I had AAA jump the car and I had driven it 80 miles back to my mechanic's garage. So I kept trouble shooting and I think I have got the answer. You need to lock the car to shut down the electrical systems between driving the car. If you don't lock the car, a lot of the electronic systems keep running. To test my theory I locked the car for a week after I had installed the new battery. When I unlocked the car and started it up it had the full 14.5 amp registering. For the last three days I have left the car unlocked in the garage. The amps have dropped to 11.5 and the while the car started, in just three days a bunch of "stuff" inside our cars is pulling amps. I realize that a lot of the folks that buy DTS's are older and only drive their cars occasionally.... and while I am older, my circumstance has me in that same "light," though i love the performance of the car.
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.

Interesting approach. Will give it a try.

Our keyless remotes do not work on our 2007 DTS after being away from the vehicle for a short period. Once you unlock the door using the key the remote will once again work. Or, if the door is already unlocked, all you need to do is open the door and then the remotes will work. Basically this means we cannot pop the trunk or remotely start the car until we open the driver door or unlock the driver door. Anyone have the same issues or know of the problem and how it needs to be fixed? The dealership tried to reprogram the remotes and thought they fixed it until we walked away from the vehicles for a few minutes, came back, and same problem, didn't work.

I have a 2006 DTS and gone through 4 batteries since July 2006.
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.
#79 of 96 Fuse Problem 2006 Cadillac DTS
May 06, 2012 (10:45 am)
I own a 2006 Cadillac DTS and Here is my problem, my fuse that operates the cigarette lighter's front and back blew the other day, it requires a #15mini fuse, so I replaced it and it was fine for a day, then it blew again, so I took a look at it and found the fuse was bad once again, I thought maybe I replaced the fuse with a defective one, it happens, the fuse box is located under the back seat next to the battery, anyway I replaced it again and it blew right away soon as I put it in the terminal, and the connector's on the fuse were very hot. Now none of the other fuses in either fuse box (under hood), or (under seat) have had any problems. Have you heard of this, and if so what was the problem, and solution, thank you.

#83 of 96 2006 DTS electrical problem
Oct 16, 2012 (3:22 pm)
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 !!!
