    Did you have any issues when purchasing your ECM from this website? I see they require your VIN to ensure you receive the proper ECM for your car but just want to be sure before I make a purchase this large. I believe my ECM is faulty as well. I have received a few P codes as well as a few others even though I've replaced them all within the last 2 years.

    Good luck getting a new ecm right now. They currently aren't making any till they figure out the problem. My car has been at my local dealer for a month now waiting on a new ecm. Aug 15th is the estimated date to resume production on them but that's no guarantee.
