Cadillac DTS Electrical Issues

Comments

  • My mother's 2007 DTS has not experieced any problems with it starting, but she has experieced it cutting off in traffic (!) at least 5 times. After the first 3 tim;es, the dealer kept it for 10 days only after my mother said she did not want it back - they did not find anything wrong, except that some codes were missing related to the brakes???? (GM even came to "investigate", but refused to talk to my mother!) They fixed the codes, then she took the care in about 3 months later for the regular oil/maintenace and to have them look at some vibrating that she was feeling in the front end, and they discovered that the brake pads were worn. They fixed them, but then she experieced the car cutting off while driving 2 more times. The dealer and GM have not resolved the problem and basically tried to make it sound like it is something my Mother is doing while driving??? My parents have been Cadillac owners for 50+ years, but this is the last one! To make matters worse, the salesman talked her into leasing the car and she has no options until the lease is up! So much for customer service!
  • Hello, I know the exact part that you will need to resolve your problem. It's called a Crankshaft sensor. I have a 2003 DTS and this was happening to me sporadically usually at stop lights or when I would come to a complete stop. Lindsey's Cadillac, which is the dealer in my area, could not find the problem. Fortunately a friend of mines had the same symptoms with his DTS and he visited a Caddy forum in which someone told him to get a Crankshaft sensor. I believe the part was roughly $60 bucks. I paid $70 or so in labor. Never had the issue since. I didn't even take it to the dealer to replace the part, I used a local Midas in the area that knew GM cars and they replaced it for nearly a fraction of what the dealer was charging. Good luck, and I am 100% sure this will resolve your Mom's DTS issue.
  • Thank you, Caddylvr. The car is in the shop right now - they still haven't found anything. I will pass on the info. Much thanks.

  • My 2008 Cad. DTS has a humming noise when the car is shut off. I suspect that it has something to do with the reomote outside mirrors. recently I see what appear to be hydraulic fluid staind near the mirror on the passenger side. Dealer is clueless.

    Here's a new one for you: Saw a streaming leak in my driveway just after pulling into the garage. Then noted a puddle under the car: Red, oily liquid. Called the dealer who had it towed in. The fluid was from the power steering. Per the maintenance write-up: A return line had a hole burned in it from contact with a battery cable. Wonder how many of the dead battery episodes are due to the battery grounding out to some part of the car.....

    I have a Cadillac 2006 DTS. If I don't drove the
    car for 7 days the batter dies. I have had 3 new batteries installed, numerous visits to the dealer and each time I get the same answer, "we checked everything and we don't find any problems". After reading all the the similar complaints on line how is it that GM can't come
    up with a resolution. Plus the battery is located under the rear passenger seat. Brilliant
    design. Is there any reason the tax payers should loan GM any money. They need to be allowed to fail and thus survival of the fitist

    Your problems sound very familiar to mine. I have
    an '06 DTS and went through the same episodes. I submitted my problems for arbitration under the lemon law, but GM went into bankruptcy. Now I am back where I started. GM needs to work on their QA
    if they expect to survive.

    I had your exact problem last year. The service writer found a TSB that addresses your problem. It is technical service bulletin number 1906368. My vin matches up to cars that need to have the body control module reprogrammed.
    Give this info. to your dealer. This hopefully should fix your problems. It fixed mine!

    So any pending buybacks under the lemon law are no longer valid if started or settled before Friday? I know the accident lawsuits that were placed before bankruptcy, both settled and pending are now against the "bad" GM. And good luck in that, as there are very few assets there. Wonder if you can withdraw and subsequently refile?
  • I have a 2002 dts with 60000 miles that I purchased a month ago with a clean car fax. I drove it for a month problem free.One day the car would not , start so I jump started it and got it to the mechanic . He said I need a new battery He installed it and on the way home I stopped at a store when I tried to start it it would not start so I jumped it and got it back to mechanic Any Ideas as to why it wont start even with a new battery ?

    So you say he put in a new battery, you drove a short distance, it would not start, BUT you were able to jump start it?

    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 had a similar problem with a 2006 DTS and found the trouble to be a poor ground from the negative side of the battery at the floor under the back seat. The floor and the threaded hole where the cable is attached had the same paint finish as the exterior of the vehicle so the ground would come and go. This also caused strange charging voltage fluctuations on the instrument panel battery voltage indicator. Once I cleaned the paint off the floor and put a star washer under the cable end, the problem disappeared.
  • Bingo a frayed ground wire led to some grounding issues. ty fixed and back on the road

    Anyone with a similar problem--if the ground cable looks good you might also check the connection at the engine module, under the hood. A mechanic friend of mine works for a local Buick/GMC dealership and indicated that they occasionally see corrosion at the engine module (positive) cable from the battery. Cut back the heat shrink at both ends of the cable (under the seat and under the hood) and be sure there is no corrosion under the heat shrink or under the terminal connections. On my 2006 DTS one end of the positive cable was crimped, the other end crimped and soldered. The ground was crimped and soldered at the battery end but not at the chassis end. I ended up soldering all of the cables at both ends: ground cable, engine module cable, and the smaller body module (under the back seat) cable. Never had a problem after doing all that.
  • CADDYMAN HERE I HAVE BEEN DEALING WITH THE SAME PROBLEM SINCE JAN 2007. DEAD BATTERY THREE TIMES. I WENT TO A LOCAL DEALER THE 3 TIMES IT HAPPENED. I DECIDED TO TAKE THE CAR BACK WHERE I BOUGHT IT.AND LET THEM CHECK IT OUT.THEY REPAIRED SEAT MODULES. REPROGRAMMED DOOR MODULE AND RAN UPDATE. THEY SAID THEY WERE NOT SET WRIGHT.ITS ONLY BEEN A MONTH. WILL SEE WHAT HAPPENS.
  • :cry: 2006 DTS Performance with 11,600 miles. Went into the store and came out turned key to start position and light on dash went on and nothing happened--car would not start, no clicking, no nothing. Half of the electrical seemed to work. Door locks and windows would not work nor keyless remote. Dash was displaying messages such as service parking assist, service air bag, left rear door open. Tow truck was called and battery was in fine condition, DTS towed to Cochran Cadillac Pittsburgh. While removing car from flatbed tow driver turned key and vehicle started. Dealer checked it out and said there was a loose ground.

    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...............
  • I had the exact same issue several times on my 06 DTS. Here is what I did that seemed to have solved the problem. Disconnect cable from battery to ground. Clean paint off floor around ground connection. Cut heat shrink away from negative and both positive cables at battery, other end of positive cable at module under rear seat, and positive cable at engine module (passenger side under hood). Soldered the crimped connection at each of these cable ends and taped the heat shrink back on (this requires a pretty stout soldering iron because the cables are rather large). Clean all connections with contact cleaner. Reinstall all the positive cables and reinstall ground cable at floor with a star washer under the cable. After doing all these things I never had the problem again. :)
  • Dealer claims this is not the problem and that General Motors tech. is now saying it is somehow tied into the Onstar module. They are going to disconnect the module and want me to drive the vehicle, and if it corrects the problem they will replace the Onstar module. If not it is back to the drawing board. The problem is, as you know, if the vehicle does not start it must be towed each and every time--a jump does absolutely nothing as the battery is in great shape!
