#537 of 896 2006 DTS DEAD AT START UP TODAY
Aug 06, 2007 (9:00 pm)
Just as I was beginning to like owning this car after several problems in my first months of ownership it would not start up at all today. Of course I called Cadillac and they are arranging a for a roadside effort to start the car or a tow to a near by dealership. This is my third Cadillac and have never had this many problems with the other two combined. Considering that this one was bought new and the others used I am of course very disappointed. The car only has 2500 miles on it.
Depending on the outcome of all of this I will have to make some choices as to what to do about this. I have what has been a very reliable Lincoln Town Car as were most of my previous cars including the now defunct Plymouth Acclaims,
Chrysler LHS and of course my two previous Cadillacs. Have other DTS owners at this forum had repeated electrical problems with their DTS models? What have you done and what was the outcome. Any suggestions as to how to get maximum help from Cadillac corporate will also be much appreciated.

Was the battery dead? You just got a new battery and this suggests more serious problems than a defective battery. I will point out that on the used Cadillacs that you had, the first owner probably went through the agony of fixing all the problems so you got trouble free cars.

I've heard of some owners having electrical problems relating to poor grounding. Hope it's not too serious. Please keep us posted.

The battery was dead when the tow truck arrived but they were able to jump start the engine so I could drive to the nearest dealership. It turns out that there is a TSB on this issue, relating to this issue. Document number given to me was ID# 1866186 Subject Battery goes dead (re program door modules) Key words DDM intermittent load module parasitic PDM # pic 4264-10/10/2006 and is referenced to 2006 DTS models. Condition Concern: The vehicle discharges or becomes dead while vehicle is parked. Recommendations/Instructions: Re program the door modules using the most current calibratation available. This problem is potentially present in models built before October 1, 2005. Above is a summary of the TSB. Dealer kept the car over night and it now seems fine BUT am not holding my breadth as this in milder form (hard starts and stall outs)
has occurred in the first month of ownership. I am working with Cadillac corporate to try to resolve this issue in that while NOW corrected I am concerned it will happen intermittently in the future. One really bad aspect of this is that Onstar goes dead so can not be diagnosed from the satellite and can't use the phone to summon help. Fortunately the car was parked in my garage when the most recent incident occurred. I had hoped to use this vehicle for longer trips but with this issue now a question I may use my Town Car in that I have not had any problems and my cell phone operates independently from the vehicle. It would be a good idea for Onstar to have a separate battery for its system for emergencies of this sort. Thank you very much for your interest and concern. I will continue to post significant updates and welcome follow up questions and information from other DTS owners.

Would you explain what you mean by stall out?
If they have cleared up the problem that was draining the battery, you should not have any furthur problems. However, taking a wait and see point of view is right.
As far as hard starts and an engine that stalls goes, if the battery is able to turn the engine over as it should, then that is some other problem.

Your absolutely right! And oddly enough it does but it is only good for a short time (a few hours at most) after main battery goes dead. In my case I drive the DTS every other day generally alternating with my Lincoln Town Car. The DTS had been idle for about 46 hours and the defect causing the power drain had also caused the Onstar battery to go dead.
I was just working on an Onstar survey of customer satisfaction online and it was so long, ponderous and irrelevant that I zapped it about 40% of completion. I have a feeling that my power issue may not have not been resolved and that I may be slightly surprised when the car is again dead at start up some morning. Needless to say unless I start getting better results from this car it will in fact be my last Cadillac. My experience with Cadillac has been going downhill, my 98 Deville was a trouble free car, 2004 Deville had a quirky cruise control and oil leak,
this car has had three in shop repairs to the electrical system. I do like the appearance of these cars and they are good performers when they are working as they were meant to but the 2006 DTS with only 2600 miles on it has been a huge disappointment so far. If you buy a car other than DTS which cars and models are you considering? Many thanks for your reply and keep in touch so we as buyers and owners can help each other to get the best value and reliability for our money.

I would recommend a Lexus based on J. D. Powers. I suspect that the quirky cruise control was more your accidental pushing the coast button than anything. I can say that my 2002 Seville was very trouble free and so far my 2007 SRX has not been troublesome. I did run the battery down on it once playing with the rear seat, but since then it has been OK.

I recently posted the following:
"There is a fix for the KNOCKING sound. Cadillac has a TSB out on this. They replaced my EVAP Canister Part Number 15941577 under warranty. Too early to tell if the replacement corrected the problem - will have to wait till the weather cools off to test."
Well, so much for the fix. Had a couple of cooler days (70s) and the knocking noise is still there. Back to the drawing board.
