Hello there!
I purchased my 2007 Fusion back in August of last year and haven't had any issues with it (only had to do regular maintenance and replace the rear brakes). But recently I developed a clunking noise which sounds like it's coming from the front of the vehicle but it's fairly hard to tell. I recorded a video of the issue (blurred out the top section of it for privacy reasons).
If you listen carefully when the car is going over small bumps you can definitely hear a clunking sound, especially towards the end of the video.
