 Went to Patterson Nissan, Longview Tx. Check engine light was on. Found a broken wire on the purge valve connnector. After 2 days, went back to dealer as they had not contacted me on doing the repair. The dealer wanted $1,700.00 to fix a broken wire on this connector. Said the whole wire harness had to be replaced. (For real) they said it was a comon problem. Nissan never mentioned the TSB, but it is a Technical service bulletin, advising this can happen. Fyi.... local garage, Kilgore Automotive, fixed my broken wire on my Nissan.  Cost.... $65.00 There is a TSB (technical Service Bulletin) out from Nissan, on this very same problem, as it is a known existing problem! Yet, Patterson Nissan of Longview either does not know about it, or they are trying to stick it to customers, to get this corrected. There is a "pig tail" available online, to fix this too. It is about $140.00, installed!  Wonder why Patterson could not do that, as well!!!  BEWARE of Patterson Nissan is either not aware of this, or were trying to screw me. Jury is out on that. Also, on the CVT TRANSMISSION, Nissan says if you use any replaement fluid, rather than their iwn, it will void the warranty. Their fluid is two to three times the price of other fluids... beware!
