When I picked my Edge up from being serviced by the Dealer, I was told that the noise when shifting into 5th was odd and probably should not happen, but since no codes came up from the computer to identify a problem, nothing could be done to fix it. They told me that Ford was called and they knew nothing about the problem. They said that probably not enough people have brought them in for service for the problem, hence Ford has not been made aware of the problem. They said that hopefully over time Ford will become aware of the problem and address it.
