Yeah, a few crank main bearing failures were attributed to cars that replaced the crank pully and that REMOVED the vibration dampner/harmonic balance. I THOUGHT I read that the Rogue pullies kept the stock dampner in place...so it should be a non-issue.
As for warranty issues....if you have some sort of internal damage, my money would be that they would blame it on the pully replacement. For myself, i would not take it in for service with an aftermarket pully on it. Not worth it IMHO, as if you have a future issue, they can go back in the records and see you had an aftermarket pully on it. Personally, I won't chance it, YMMV.
