Any common problems with slightly older Primes?

I'm currently looking to buy a used Prime, probably from 2021, although there are a few low mileage 2017s and 2018s in my area that are tempting. What I want to know is: are there any serious problems that specific years of the Prime tend to run into? For example, my 2007 HiHy has problems with the battery which were common in HiHys from that year. Any consistent issues with specific years of Prius Prime?
