Let's no go there about QR25DE reliability. Besides the issues with the butterfly valve screws, there was the failed pre-catalytic converter issue on the '02-'03's (both Sentra and Altima). I was one of the unfortunate ones with pre-cat failure and had my '03 Alty's engine replaced under warranty at 82,0000km due to high oil consumption. I got great service from the dealer and Nissan seems to have fixed the root cause of the problem. The replacement motor now has 125,000km on it and no issues.
I do not own a Rogue, but my test drive of one was very positive. The 2nd gen QR seems to be much smoother. And one would assume this secon gen motor would have the bugs worked out. I would love to test drive a used example with a few miles/km on it to see how the QR behaves.

I agree, they have been using the QR25 in the Sentra and Altima for quite a while and it has been a fairly reliable engine, unless you have a butterfly screw come loose...
If they put a new engine in, I don't see what the problem is. Chalk it up to bad luck.
