On build quality, I have had four Fords in a row, a 2005 Explorer, a 2007 Edge (first year), a 2010 Fusion Hybrid (first year), and a 2018 Fusion Hybrid. All were solid, squeak and rattle free, with only the occasional minor issue.
I drove the 2010 Ford fusion hybrid for 8 years (115k miles), the build, battery and engine were practically the same as when i bought it. I only traded it in because I just wanted a new car at the time. I would have waited for the launch of the MMe had I known.
My 2018 Fusion is well-built, super quiet, and only requires maintenance every 12 months. Every aspect is Improved over its predecessor, especially the software in Sync 3. My car also does OTA updates when it is parked in my driveway and connects to my home network (although not as all-encompassing as the MMe’s OTA will be).
Ford is also taking advantage of all the available data and invention of the new EV players like Tesla and Rivian.
all that said, i feel we don’t have too much to be concerned about.
