 I bought a new 2005 in Jan-06 in Jun- 07 I have 80,000 miles on it.  This is my 5th Nissan I have purchased for use in my business and the only major thing I have ever replaced was a clutch at 200,000 miles.  My last was a 1997 & I replaced 2 clutches, a starter & alternator. I traded it at 487,000 miles & the others were over 300,000 miles. I got them all from the same dealership. Now at 80,000 miles the transmission seal leaks & the flange in rear-end went. Nissan dealer said it would take 10days to get the part. The same dealer sent my mechanic the wrong part 3X. After 2 wks & 20 calls to corp. no one returns my calls & no answers when they'll have the right part made, no loaner.
