Nice find. I was so close to purchasing an Accord. I just fell in love with the 6 during the test drive.
The noise is normal. I had that with my BMW E90. It's annoying but it's not like I'm sitting in the garage listening to it.The 6 also has that high pitched humming electronic noise when it's off. And that noise will be there from 1 minute to 10 minutes, I thought it was weird, but thinking it's probably normal....Is it normal? Should I ask the dealership?
The Fusion does have build quality issues, I inspected two Fusions parked near my work today, and both have door misalignment issues. On one of them the door sank so much that it actually bent the bottom corner of the door a tiny bit....really glad I passed on the Fusion and picked the 6 instead.
That is actually a good read and although I might sound biased due to the car that I ended up choosing amongst the competitors, it's spot on.
