 My 2013 Nissan Altima was a dream to drive for 4 years, then suddenly at 68,000 miles the transmission started shuddering and needed replacement.  I take impeccable care of my vehicles and paid attention to all recall and TSB’s to follow manufacturer recommendations.  The CVT software update succeeded in getting the transmission past Nissan’s 60,000 mile warranty period but did not fix the problem.  Now a $4,000 repair is all on me.  More than 10 years of producing these transmissions and they still don’t have it right.  They know they are junk but refuse to do anything to address it.  Absolutely unethical fraud. I will never buy another Nissan.
