Hello, welcome. My name isXXXXX will do my very best to assist you with your question. I apologize if you have been waiting long for a response.

From what you are describing this issue that you are having is infact consistent with a DEM module failure which is very common on these vehicles. I am also a warranty inspector and I have inspected this issue many times. To correct this issue the DEM would need to be replaced and programmed to the vehicle.
