Rattle noise under hood . Found fan for a/c coolant bearing failure fan blade wobble noise started while driving to the market.
After about 34,000 miles I hear a rattling sound coming from engine. After getting diagnosed the Nissan service department in wake forest nc said that it was my fan motor and it's out of warranty. So I did my research and found out a lot of Pathfinder owners are dealing with the same exact issue. I heard the noise immediately after turning my air own pulling out of my driveway.
