Hey team Jaolop,
I took my 2013 Fusion (1.6l turbo) to the dealership due to the constant emission of (unspent) gasoline odor. This had been getting worse for a few weeks. The dealer replaced the entire fuel injection assembly; apparently that's all one big, unified thing now. The whole deal was covered under warranty, and apparently I'm the first to have this service performed at what is a pretty high-volume Ford dealer in Phoenix. The recall notice has apparently not gone out yet either.
The gas fumes were getting pretty crazy...not sure if enough for ignition, but that was certainly a concern for me.
Gentlemen, start your service departments!
