    Dts Problem!

    My 2006 DTS is going crazy! The door locks constantly lock and unlock while driving. While this is happening, the sifter indicator on the dash is moving from drive to neutral to reverse, to park which make the engine stall! I replaced the sifter control.....$300! Still the same problem. Please help, any suggestions would be appreciated

    Re: Dts Problem!

    I would take it and have the trouble codes read at the dealer.
    The codes will tell you what is wrong with it so you don't just throw parts at it and HOPE it fixes it.

    My first guess would be the door module, but it could also be a number of other things causing it.
    Have you worked on the radio lately??

    Nothing has been done to the car except regular maintenance. Seems like there's a bad connection somewhere.

    I agree with Jim. With todays electronics, many systems and wiring are multiplexed making it hard to diagnose. Let the dealer scan it for codes.

    Could be a bad or corroded ground wire. I'd start at the battery itself. Lift off the rear seat and have a look at the posts. Even if they don't look too bad, make sure the connections are firm and secure and wipe off any crud that may have accumulated over time and then spray with some battery post protectant. I still use those old felt rings. They're old school, but I swear they work.

    Also, check to make sure a fuse hasn't come loose. Good luck.

    I had similar problems. Not as bad as yours. All was corrected by a Software down load at the dealer.

    I was also thinking this sounds like something that can be fixed with a software flash before trying anything mechanical. Nature of the beast these days.

    lthomas11002, have you been to dealership yet for your issues? If so could you please update us at to what went on with them (whether there was a fix or not and what was done to the vehicle while it was there). Thank you!

    This thread has me thinking,if the heater fails to come on when using the remote start would a software "fix" eliminate this annoyance? The heat works normally otherwise.

    I would think it is very possible that an update would correct that problem.
    My dealer spent over TWO AND A HALF HOURS installing updates to mine about at the end of 2007...
    There were a LOT of updates to install.
    I was back in the service dept watching and talking to the Service Manager while he did it.

    I have not experienced a lot of the problems that other people have mentioned.
    That may or may not be due to all of the software upgrades I have had done.

    Re: Dts Problem!

    I have a problem at times where the power windows and door locks on passenger side are dead. If I shut off the car and open the door and close it the problem goes away for a few days. Has this happened to any of you?

    Absolutely. That was my exact problem. It was really annoying, especially if I had a passenger with me. It was corrected over 3 years ago with a Software upgrade and since then I have never had that problem again.

    There was a service bulletin out on this (not a recall) but it may be covered anyway. Check with your dealer. I’m sorry, I have no idea what the bulletin number is. If you have an extended warranty it would be covered.

    Good luck.

    Re: Dts Problem!

    Try this. Reprogram your door lock options, select another mode, drive around for a while if that dont work disconnect battery both pos. and neg. for about 10 min. this would be like a computer reboot. The car will hopefully zap the electron gremlins. Mike

    Re: Dts Problem!

    Sounds like there are a lot of software upgrades and the average customer does not know about them. What do they do? I'm thinking of going in and telling them to give me the full menu.
