Not really. When was the last time you went out to eat and told a friend, "My server did their job" or "My food was what I expected"? Probably not very often, but if you had poor service or bad food you probably let someone know about it and probably right away. It's the same case here, you're hearing the loudest voices expressing their complaints, but people don't post when their car is just "doing what its supposed to do".
Also take into account the messengers - car forum members. We're pretty quick to alert others to issues, actual and potential and (most of us) are also fanatical about our vehicles - if there's something wrong in the least we're going to get online and ask about it and what we can do to fix it. We're also talking about a sports car that in many instances probably didn't get driven gently right out off the lot, amplifying potential areas of vulnerability.
I'd say that in most cases an engine with the age and miles the OP is looking at purchasing has most likely had any issues that Nissan could take care of already addressed. That's not to say that the current owner has maintained the vehicle since then and certainly it should be inspected like any other used car, but I wouldn't shy away from buying one.
