Transmission Not Go Into Gear problems of the 2015 Nissan Xterra

Bought my x-terra brand new and was told is has a bumper to bumper 36,000 mile warranty, at 22,000 the car would not shift into gear. Had it towed to a Nissan dealership that is saying the clutch is bad from normal wear and tear and not covered under the warranty. We've read a lot of other reviews of this happening to other people as well and want to report it. Both drivers in our household are experienced clutch driver with a combined 20+ year experience. I called Nissan customer service to further investigate and they called the dealership and just "took their word for it" nothing was really investigated at all. Poor customer service on both ends. I called the dealership we bought it from that is 4+ hours away from our current home and they said they would've taken car of it and fixed it under the warranty. We can't have it towed 4+ hours away after being taken apart. Bottom line Nissan has something going on with their clutches, and is blaming it on the consumers and not abiding to their warranty.
