Chrysler Pacifica reliability?

I bought my wife a 2017 Pacifica new and haven’t had any real issues with it. The oil housing on the top of engine started leaking at 130,000 miles and wasn’t an expensive fix cost about $300 to have it replaced. It’s the part with the oil cap is molded into. It gets old and cracks. Common problem on all of those engines even in the jeeps too. We have over 140,000 miles on it now and haven’t even changed the brakes yet. The tranny shifts ok but is quirky and has a hard down shift sometimes but it’s been like that since day one. It gets almost 30 mpg on the highway too.
