I have a 2015 Eco. My truck sometimes shutters when shifting, mostly from 2nd to 3rd gear, but occasionally other times as well and seems like it is getting more frequent. The dealer has tried to replicate the problem multiple times but was never able to do so. The last time I took it in I emailed the service advisor a few videos that I had taken while driving when it happened. They kept it overnight and said that it was just boost escaping the turbo? That seem right? My warranty is going to run out soon and I'm worried right after it does, I will have a major issue to deal with.
