Nissan doesn't stand behind warranty.
 Clutch catastrophically failed at 47,000 miles of mostly highway driving.  Despite a 60,000 mile power train warranty that was 100% silent on clutch exclusion, Nissan just said "no".  They said they couldn't prove it was a defect-maybe I abused it, therefore they refused to cover it.  I've been driving vehicles with standard transmissions for 40 years without one ever failing on me, so I know with 100% certainty it is a defect in their vehicle.  When I asked their mechanic who did the work on it how long a clutch should last, he said a hydraulic clutch on a vehicle like this should easily last 150,000 miles, but his name wasn't on the dealership sign.   When I appealed to the Nissan Regional manager he just said "no" with no explanation other than "he had reviewed it".
