Thanks for the article.
How can you find that and not the dealer?
That's incredible.... you know I really think this was the problem.
This is well discussed on the Giulia forum (a separate entity from this board). When you are 80% or 90% (or more) of full steering travel and going slow, the inside wheel will judder a bit--it feels alarming, like the front end is shifting in an unpleasant way, but it is natural and nothing to be concerned about. It is easy to do because of the steering ratio and somewhat large turning radius.
Sadly, FCA has little control over its dealers once they establish a franchise. Franchise protection laws make it very difficult for manufacturers to do much about low-performing dealers---they can't just yank the franchise license and give it to someone else. If they close a franchise, there are state guidelines about when and where they can open another one.
It sounds like the dealer has no clue what they are doing. I know you said that the CEO was nice, but ultimately he is responsible for the poor training, lack of loaner car, poor storage of your car, poor communication of repair work, and overall the total nightmare experience you have had. No wonder why FCA was slow to take action--if there was nothing wrong with the car in the first place, they would lean on the dealer to figure it out and put it back together.
No excuses overall, but I do hope that you give this awesome car another chance. I have over 5k miles on my 2018 and it has been a perfect ride (and a heck of a lot of fun). Never, never, let that dealers' service department touch another car of yours.
