Extreme squeal coming from belt/pulley system. Shop replaced drive belts and installed new idler pulleys. Squeal still exists. Going back into the shop this week to check for binding pulleys on accessories. Shop finally ended up replacing inner bearings (2 of them) in the small idler/guide pulley between the drive/crank pulley and the alternator pulley. Odd design on the part of Nissan but the shop finally got rid of the squeal.
