As a car guy, I hate myself for saying this, but the Prius is leaps and bounds more reliable. The Prius can give you 200K + miles without any issues. It's well known for doing that. That hybrid battery could be of concern at 11 years, but I've seen some go in excess of 15 years before needing replacing. If it needs replacing, it's expensive, but once replaced, you have another 10+ years to go. The gas engines are very reliable as well a the hybrid system is as well. The Murano has electrical issues and don't get me started on the CVT. You'll be lucky to even get 100K miles before having issues.
