What Went Wrong? 
2005 Nissan Xterra SUV Off-Road 4WD 4dr SUV (4.0L 6cyl 6M)
How an Alternator Died at 21,00 Miles! 
 After having a 2000 Nissan Xterra that never ever needed a repair, I purchased the new one in 2005, all two months of them. Now at 21,000- miles, my alternator and idling arm are dead. Go figure. Dealership thought the progressive noise it made was lack of oil! Wrong! New dealership can't explain why it happened. Neither can I or the next dealership I may have to go to,,,probably NOT Nissan!
