Thank you for your many emails re: problems with the caddy DTS. After six trips to the most unhelpful dealer (Coleman Cadillac, Bethesda, MD) where they blamed it on Onstar and finally on my Mother, she went to a lawyer. He sent a letter to GM and their customer dis-service person contacted my mother via phone and email and basically said it was her fault. No wonder they went bankrupt!
 
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.

I noticed recently that the lights inset in the front bumper do not come on when the headlights are turned on. Is there something you have to do to turn them on or is it an electrical failure? Thanks in dvance if anyone can help.

#66 of 96 Electrical problem solved Cad. 2006 DTS by usabravo

Previously posted messages no crank/no start. Dealership and GM believed the problem to be a module. I kept telling them it sounds like a grounding issue. Eventually, the electrical would die completely while driving and then 10 seconds later electrical would come back on. No speedometer, no power windows, no power locks, no gas guage reading, etc. Display would flash all kinds of crazy messages.
 
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.

I have a 2006 DTS that when it sits for a week the battery went dead. It went to the dealer 4 times and they said they checked everything out and said it was the radio memory that was draining the battery. So they put a switch under the dash to cut the radio off when parked. This did not work and you also lose all your preprogramed stations.The real reason is that the ON STAR system is draining the battery as it communicates with the car all the time. When you open the door it thinks you are going somewhere and runs a check on the whole system. The dealer WILL NOT disable the ON STAR no matter what you say. If you leave your DTS at the airport while you are on a 2 week trip to Europe you will have a dead battery when you return. If you use the car every day you will be OK, but if it sits the only recourse you have is to put a battery kill switch on the car. You will lose your radio stations but your battery will be OK. This is not a easy task as the battery is under the back seat and you don't want to keep lifting the seat out to turn on the switch. You need to run two cables from the battery to under the hood where you will mount the switch. It cost me about $200 to have this done but it sure was worth it. I like the car but it is going BY-BY when I can afford to dump it and buy a non-ON STAR car. I have always had Lincoln Towncars that sat for months that always started right up. So give up on the dealers as they will jack you around forever and never solve your problem except tell you to drive it more.
 
GOOD LUCK

I had the same problem for the 1st two years I owned my '06 DTS. After 4 batteries
and many service calls I had to utilize the Lemon Law to get it resolved. The
car has been fine since.

#72 of 96 Service Air Bag by idavid

Feb 04, 2011 (2:38 pm)

I have a 2006 DTS with 37,000 miles and I'm getting a Service Air Bag message when I start the car. Does anyone know where I can take the car to get the error codes from the system other than a dealer? I would like to try to fix this problem myself if possible. I'm in the Detroit Mi. area. Thanks

sometimes (often actually) a store like Autozone or Kragen/Oreilly will read these for you for free. Tell us the code and we'll advise you further.
