Milan65

Older post so you may not have this issue anymore. Just in case. My 2011 V6 Milan (70K miles) always felt as if it was stumbling under constant speed or light acceleration. It felt almost like pulling a trailer. It was at the dealer for weeks undergoing every test they could do. Long story short, after a lot of research I decided to re-look at the rear (dogbone) motor mount even though the dealer checked and determined it to be within spec. I replaced it with a solid version from Steeda (https://www.steeda.com/fusion/steeda-ford-fusion-engine-mount-06-12/). No more problem (at least not noticeable). The inner part of the OEM version gets softer and softer. Might not be your issue but I really hated the symptom and was extremely pleased with the result.
