Cadillac DTS Electrical Issues

Anyone having a battery drain problem with 2006 DTS Luxury III? My battery has been lasting approximately ten days prior to failure. Car has less than 500 miles on it. I agree about the lousy fuel economy.

    We have had this problem. We bought the car Dec. 02, 2005. On February 10, 2006 car was setting in our garage and would not start. When I bought the car the mileage was 56 and the first time it would not start the mileage was 412. On May 01, 2006 the mileage was 974 and car would not start and it was setting in my garage,again. I did not buy this car to have to drive it every day or every week. The dealer claims that they cannot find anything wrong the first time, they charged the battery and ran a series of tests on it. The second time it happened, they replaced the battery, charged the new battery and ran another series of tests and said they could not find anything wrong. I know of another Cadillac (2006) in the neighborhood that has experienced the same problems. This must be an engineering flaw in the electrical systems, computer, or something. Each time the only solution that the dealer gave me was to drive the car more. I paid too much for this car for this to be happening. My other car did not have this much mileage on it until it was about 18 months old. It still started and never gave any problem of this nature. I also hear that the Corvettes are facing this same problem on a regular basis and I know that this is not a car that people want to drive every day. There has to be a problem in the systems of these automobiles. If it can happen in my garage it can happen anywhere. I do not believe that driving the car more will solve the problem it may only delay or hide the problem for awhile.

    I don't own a DTS but my father is looking at one. The issue with modern cars is all of the electronics that use a small (very small) amount of battery power to maintain settings and memories. For the average person who drives a car daily, it never becomes an issue, but judging by the miles you noted, your car is driven very little, so when it sits, the various components and accessories gradually discharge the battery. Even something as simple as the clock in the car will wipe out a battery if left long enough. Other than driving the car more so the battery recharges regularly, the other thing you can do is get a trickle charger to plug in when the car is in the garage and sitting for extended periods which would keep the battery maintained at the proper charge. They are relatively inexpensive and are available at most auto part stores or somewhere like a Sears auto center. By the way, this was explained to me by an electrical engineer who used to work for a large truck manufacturer. Hope this helps.

    I have an '03 Deville and also drive it very little -sometimes only once or twice a month around town for a day. I also use it on trips - that's why I got it -for the 400-800 mile trips I take every couple of months. I replaced the battery a couple of months ago just because it was 3 years old not because there was anything wrong with it. The car always started even though it had not been driven for weeks. I think that there must be a problem with a car that can't sit for a month without a battery charge. Another thing to remember for those of you who sparingly drive a car. Oil should still be changed at least every 3 months. It breaks down when the car is not driven. My mechanic friend says that this type of driving is considered "severe use". Forget about the usual 3,000 mile oil changes. Just do it every 3 months.

    The first time that it happened the car only sat for four days, after being driven for more than 100 miles. The second time it happened the car sat less than ten days. I had another vehicle that sat six months and it would still start. I believe your explanation by the electrical engineer, but this tells me that the electrical design is not keeping up with the loads that are being put on it. This in my opinion is a design and engineering flaw. If GM knows this then they need to make this apparent to potential customers and/or not overload the system they have designed.
  • Hi all,
    I hope someone can help me or I will be forced into selling this gorgeous vehicle!! I just purchased a 2004 DTS with every known option and only 37000 miles. It is just beautiful....one BIG problem....my husband is 6'4" and the drivers seat does not go back far enough for him to be able to drive comfortably. His knees are literally up against the dash!! Is there any solution to getting the drivers seat to go back a few more inches?? Hope so or we are going to have to sell this super luxurious baby!! Thanks so much and hope I can get a solution!!

    My 2003 DHS was that way :(

    My 2006 DTS goes way farther back

    Check with service manager before you get rid of it. Couldn't do anything on my 03

    Good luck

    My '03 is about right but I'm looking forward to the next DTS with more seat travel. What I'd do is check -not with the dealer - but with a body shop. It might be possible to remove the seat and move the track back. Unless the track is on a hump like my new '90 Mitsubishi Galant which I sold in a month because of seat travel it should be possible to move the track back. You'd lose some back seat space but probably nobody rides back there anyway. The dealer most likely will try and sell you a new one. Let me know what the body shop says.
  • dispencer1dispencer1 Posts: 489
    So what did you do? Take it to the body shop or what?
  • Well, unfortunately, I have not been able to do anything. Cadillac said it doesn't recommend any fix, the dealership was useless and body shops want seat extensions like the ones available for Ford Mustangs.....leaves me with not many options!! I was really hoping for a better response, but no one seems to want to take this project on!! Any ideas???

    I have a 2006 DTS Performance - I drive it about once a week, and I have not had the battery drain issue yet. I had heard of people having the same issue with the STS, which is one of the reasons I went witht the DTS instead.

    I know that On Star wakes up and polls periodically for a specific number of hours after the car is shut off. It is, however, supposed to stop waking up after the car sits for more than X number of hours - 8 hours, if I recall.

    Any chance you have a battery with a bad cell? Would not be the first time this has happened, even in a new car.
  • Went to BBB and challenged GM on battery drain. GM will not do anything to correct the problem. My understanding is that dealers have received a letter from GM telling them how to better keep batteries charged up on lot and improve customer satisfaction with this problem in the future. What does that do for you when you are away on a long trip and come back to an airport at midnight and your caddy will not start.

    I have an 06 DTS, and the battery had to be replaced with
    450 miles on the car. It sat for 2 weeks, while on vacation.
    Upon my return the car wouldn't start. Roadside Assistance
    replaced the battery. I called Cadillac customer assistance
    and essentially told them what you stated about the design
    problem. The response I got from the person I spoke to, Terlin, she never heard of the problem. I think the Cadillac engineers need to assess the problem. There are other problems I am having with this vehicle which I will list at another time, as I am in the resolution stage at this point.

    I hope you still read this conference. I just bought a 2006 DTS and have had the same problem. Coincidently enough I also spoke to someone at Cadillac with same name and was given a response similar to yours. Can you bring me up to date as to what has happened with your car since your post on November 30, 2006. Any information you can provide will be greatly appreciated. The car was sold to me new and has only a little over 400 miles on it. I am taking the car to the dealership next week and am eager to offer suggestions as to how to resolve this problem.

    I also just got a 2006 dts and the car wouldn't start after having it 1 week. Though it has 17,000 miles and 1 year old. Can you tell me what has ahppened in your case so I can be more informed with my dealer. It sounds like the same problem.
    Thanks!

    what has happened with your battery problem? I too seem to have the similar problem.
    Thanks,
    Chris

    The dealer changed the battery and "noted numerous low voltage codes stored in BCM. ECM and TDM. Cleared codes" this is the text from the invoice. Hope this will help you resolve your cars problem. It has only been three days since this repair was done and car has been okay since then.

    I now have an additional piece of information. When I had the car jumped by cadillac service the man told me that there is a software update to Onstar. It seems that Onstar keeps communicating with the car and runs down the battery. My battery tested fine. So far, it is working fine after 1 week.
  • I BOUGHT A NEW 2007 CADILLAC DTS, AFTER 3 WEEKS AND 800 MILES, THE WIRES IN THE ENGINE BURNED, CADILLAC WOULD ONLY FIX THIS "MINOR MALFUNCTION" AS THEY CALLED IT. I WANTED A NEW CAR. THE CAR IS A LEMON. THEY HAD NO CONCERN ABOUT ME, IM VERY DISAPPOINTED. THIS WILL BE MY LAST CADILLAC AND GM CAR. AVOID THIS CAR.

    We bought our DTS-III Performance in January 2006 and it has performed beautifully until Monday. It was completely dead. We could not pop the trunk and nothing would work. I put a "digital" charger on the car and it said the battery was "open." Then I put an older "dumb" charger on it and it took a charge so I brought it to the dealer where they told me they couldn't find anything wrong. We even had a "check engine" light on but they said there were no codes stored in the computer. When I got home with it I looked at the car with my laptop computer and it said there had been 20 minutes and one "warmup cycle" since the last codes were Cleared so the dealer was pulling my leg when he said there were no codes.
    :confuse: This car now has about 14,000 miles on it. It had been sitting in the garage for only one day. Sometimes it sits for 3 or 4 days and we've never had this problem before. The dealer said there was another DTS in at the same time with the same complaint. They said "drive it for a few more days and maybe it will happen again--then call roadside assistance" Wow--is that lousy service or what?
