 I bought a 2006 Nissan Maxima in 2008 with low miles from a dealership.  By the time it hit 72,000 miles, the transmission was jerking. I called the dealer who said the warranty was up, so they could not help me.  What?  R U  kidding?  I've had two Maximas  a 1998 and a 1999 that performed well over 200k miles.  I called headquarters who told me to get a diagnosis from Nissan service only which costs $130.  Service rep said I need another tranny which would cost $3,000's .  that's for a rebuilt transmission.   Waiting for  headquarters to take action.
