Took the Murano in for a load noise under the hood on the pulley side. Had to leave it there all weekend, bummer. After I dropped it off they couldn't get it started and had to push it. Called monday and they hadn't done anything because the battery was dead, didn't even call me. Was told they couldn't do anything without replacing the battery first, for $150. Anyways the whole battery issue is solved, got an interstate for $50. The story I got initially was that the bolts on the alternator were too tight and had been stripped out, they could tell this just by looking at it, HOW??? Next is that the idler pulley is bad from age??? 1 year 3 months and 36,000 miles is old for a car? Anyways new story this morning is that idler pulley was replaced, alternator bolts are now not stripped, just were too tight ( this still baffles me). Asked if alternator was loose from stripped bolts and if that caused the battery problem. that was when told that the bolts were never stripped. Whole thing just seems fishy to me. To top it all off none of this is covered under warranty, just my extended warranty which has a $100 deductible.
