Are Altimas reliable?

Hey guys I’m looking at a 2019 Altima SR w/48k miles on it. I am just looking at the Altima rn because I see that it seems to be a reliable car, but I am also hearing many people talk badly about it both online, my workplace and also my mechanic whom I trust. So I was just curious what everyone’s thoughts on it were. I plan to keep it maintained and not drive like a fucking lunatic like some other Altima drivers, but I do live in a mountainous area.
