The turbo? That's laughable...you need to find another dealer (if possible). I'm betting it's the shitty auto transmission that comes with the EB, as noted above.
With regard to the engine, I probably had unreasonable expectations. I thought it would be a larger version of the 1.6 EB I had in my 2015 and 2019 Fiesta ST’s. It ain’t, not even close.
The transmission is pretty much a turd.
