    I have a 07 LTZ that is crazy. It thinks the lift gate is open, when its not. This means you have to turn off the interior lights to drive at night otherwise they stay on. The power liftgate sometimes makes a really bad knock noise as it is closing. Sometimes when we hit a bump the door locks freak out switching several times without any buttons being hit. It has been to the dealer, twice, and of course they could not get it to do it. :grrrrrr:

    Anyone having these types of problems? Please help!

    well, you get it. I'm totally 100% frustrated with dealerships and welcome the chance anyone has the ability (aka "still under warranty") to get the service department there/anywhere to do something. Maybe they'll be tired of seeing you after a time and actually spend some time looking for the problem and/or actually replicating the problems.

    Good luck with it all! Hopefully someone here will have better advice for you. :)

    sounds like a bad ground wiring to me. have them run an electronic ground test among a few other things. you might have to leave it there all day but its worth it in the long run.

    Good luck with that one. I would say the dealer is your only option here. i once owned a van that did the same thing that when hitting a bump or bumps, the interior lights would flash and the door chime would ding.

    thanks I will start there. I am frustrated with the dealers and the lack of caring and attention to service.

    the dealears care but a lot of techs are dumb they just put on parts, and electronics is everything these days and most techs avoid learning it. Like said before its probably your ground wire it could just be loose or maybe its corroded. also have them check the TIPM :totally intergrated power module" it controls everything. also you could get your own scanner and run a dio on it but they probably already did that. Anyways good luck :money:
