Bought a 5spd Fusion S in July. Since I've had it, I have noticed on several occasions that when I let the clutch out in reverse, the back right wheel area makes a loud bang before the car starts to move. The first time it did it I thought I ran over a tennis ball. It dosent do it all the time, but it usually does it when I am backing strait out of a parking space or my garage. Also, has anyone else had trouble with clicking hubcaps? I noticed the day after I bought my car that the drivers side front hubcap made an annoying clicking sound. Took it to the dealer and they couldnt find anything wrong with it. They said they had a lot of complaints about the fusion hubcaps but ford hasnt decided to do anything about it. After I brought it in the clicking disappeared so I dont know what was causing it.
