    2007 cts ecm issue!!!

    So yesterday, my key got stuck in the ignition with the Theft Mode System light on, tried everything i could look up to make it stop doing that but no luck. So I brought to a mechanic and he said that the ECM is needs to be re-programed. So than i brought to the Cadillac dealership and they said most likely i need to replace the ECM, but they haven't done the diagnostic check yet, he just said 9 of 10 times thats the problem. big thing is he said it'd cost $1100 ($800 for a new ECM, $300 for reprograming and labor) to do, and before i go blow over a grand on this i was hoping to see if you guys had any issues like this. I'd greatly appreciate feedback, thanks!

    Your best bet is to get a salvage ECM and have the dealer reprogram that one to your vehicle's specs. That's ~$800 saved

    ----------

    BTW according to GMPartsDirect.com the MSRP of the ECM is $537.14 $800 is quiet the mark up, I guess that's how dealerships earn their great name!

    MSRP Online Price
    $537.14 $279.31

    I would either do what CTSM said and find one at a salvage yard or on ebay. Or buy a new one online and have the dealership install the new one. that way you only spend about 800 to 900 dollars, you get a brand new ecm that will come with a warranty of some kind, and you'll save about $200.

    Hello james.koukoulis,

    I am sorry you had to deal with this issue. I understand your hesitation if the dealer confirms it to be an ECM replacement due to cost. I see CTSM offered insight to your situation. If you would like to further discuss anything with us, please reach out via private message or by email at socialmedia@gm.com.

    Sincerely,

    Laura M.
