 Read the reviews and do your research before considering the purchase of a 2013 Nissan Altima.  Our CVT transmission was just replaced at 64K, 4k outside the warranty.    There are numerous complaints all about the same issue!  Shudder and juttering and then it just quits - torque converter locked up.  Luckliy for us it happened while we were coming to a stop! Stay clear of this car - it is going to cost you $3k-$4k some day for a transmission.  Nissan needs to admit that Jatco (75% ownership by Nissan) has built another flawed CVT transmission and start the recall.   They admitted this issue with 2003 -2010 CVT equipped cars. If you have had an issue with your 2013 Altima, we all need to complain to the NHTSA and have our cases logged.www-odi.nhtsa.dot.gov/VehicleComplaint/
