Pay attention to your transmission shifting. If it shifts hard or doesnt downshift when you step on it, your transmission may be the source of not having power. Check my thread on 2012 R/T transmission problems.
Other than your perception of slowness, what makes you think they "de-tuned" your ECM? What on earth would make them do that even if they could -- which I'm pretty sure they can't.I got my Durango back with a new transmission and the ECM was de-tuned. Noticably slower. I'm in the middle of a lemon law case.
I'm not familiar with CA lemon laws, and while surprised, I'm glad you got the satisfaction you were looking for. I think you mean your attorney took the case on contingency basis. But that is usually only for damage/injury cases where there is likely to be a monetary settlement. If all your getting is a new car, how is your attorney being compensated?JRRF, I thought the softer, slower shifting was just in my head because it was gone for a month but I remembered the D having more guts. So I test drove a new R/T at another dealer. Big difference. Also, I saw a new sticker under the hood with "PCM performance update" hand written in marker on it. I called my service advisor at my dealer and asked about the sticker and my perceived slowness. He said it's normal to update the software and my update was to protect the new transmission, hense my perceptions and my de-tuned ECM.
My attorney received a letter from Chrysler asking for my loan payment history and registration last week. He was told by a Chrysler Rep in Irvine Ca that they will be taking my D back before March. The circumstances of my D clearly violated CA Lemon law. My Attorney handled this case on consignment
