They did drain and flush the fluids and seemed to take care of the problem after i drove it again on a cold start. I do have a smell of that diff oil after i got home from the dealer , but i guess its normal till it gets more settled in. I am happy my car came out the same way i brought it in. I did contact GM for a extra level of support and they did do everything they can to make sure i was pleased. I was also happy they kept my car inside for the few days it was there. Overall i am feeling much better my car is back in my Garage! Also you can use this tool/advise as some others say works well, all the dealers get the customer surveys and rely on them 100% -

Awesome to hear! Hopefully that is fixed and the noise will not come back.
