My 2017 does the same thing - hard acceleration and it stutters at ~4500. I'm at about 350 miles so far, and my expectation was that the limiter should be off by now. When I asked the dealer, she told me I should be finished with the rev limiter by 300 miles.
.
From what I've heard it's the number of running hours, which is twenty, that will turn off the lower rev limit.
I guess if we both have the exact same issue this is a break-in "feature" and not an actual issue. 😏
