Having had experience with a 2015 and my current 2020, they have improved so much. The new engine is much more refined, although still a noticeable 4 banger, no rattles, and minimal creaking compared with the 2015 (only creaks when it sits in the sun and gets really hot). Mine is the last year of the Alabama built ones, and what I’ve seen and heard is that the SA built ones are even slightly better. I do have an occasional harsh downshift with my 9G which I didn’t with the 7G plus, but apart from that I really can’t complain, it’s way better built than my first one, and much more solid. I will say though, that this new one still isn’t as solid as my old 2010, which had 120k miles when I got rid of it, and was basically a tank.
