Good gas mileage cars, but depending on the year of the car seems to affect how good it is. Check out this sight for the year Ford Fusion your looking at to see the complaints, problems with this vehicle... www.carcomplaints.com
Yes, some early models had transmission flare issues. Annoying , but the cars still functioned. So research is key.
Pretty good overall and the hybrid version is very dependable.
Yes, a guy at work has a 2015 model and has had zero problems with it. He and his wife bought it new. HTH. -Jim
Yes, I've owned two, one from each of the first two generations. They're excellent cars in so many ways. The 4 cylinder models 2006-2009 have a not-so-amazing Mazda automatic transmission that likes to be maintained well. The Aisin transmission in the 2006-2009 V6 models is excellent in comparison. The 6F35 transmission in the non-Sport variants of the 2010-2012 models is really hit or miss. They had some software issues in earlier years, mostly sorted out by 2012, but YMMV. The V6 models are NOT known for their fuel economy. Both of mine have been the 3.0 V6, in two different generations of the engine. The 2011's 3.0 was slightly more efficient and a significantly more powerful engine, but averaged about 21-22 mpg. The 4-cylinder in the 2010-2012 is really very good, smooth and relatively powerful. My strongest recommendation for reliability in a Fusion is to go with a 4-cylinder with a manual transmission (only available on the S trim, if I recall), or to go with a 2010-2012 Sport model with the 3.5L V6 and Aisin automatic, if fuel economy isn't the very top priority. You'll find the rest of the car, suspension, etc, is really very good.
