I have owned my 2012 v8 nv for 1month now it has about 1000 miles on it, and I have noticed about 1 out of 5 times I turn on the van and drive that the transmission will hard shift, until I turn off the engine and come back later and its running normal again. I have recently taken it to a local nissan dealer and they can't get it to happen while their test driving it. When its working it drives just as smoothly as you could ask. Not sure if maybe there is a computer problem or if its in the transmission.
