2014 Nissan Sentra Sedan SV 4dr Sedan (1.8L 4cyl CVT)
Great for the first 1,000 miles
 Purchased my 2014 Sentra SV used with 38,xxx miles in August 2015. Everything was fine for the first thousand miles then the transmission began slipping. I did my research on several cars before buying, including the Sentra, but dismissed the claims about the transmissions- BIG mistake. Now, not even two months after purchasing, i have an appointment with my local Nissan dealer to look at my transmission. It's jerking, little or no power, sends the RPMs up to 5,500 randomly, and I feel totally unsafe in this vehicle. This is my first Nissan and likely my last. My two prior vehicles made it to well over 100,000 miles with few major repairs and certainly not a transmission. A 2014 model vehicle with less than 50,000 miles should not need a new transmission. Update---Ended up trading the vehicle in Apil of 2016 for a 2016 Hyundai Veloster. I shouldn't have left Hyundai when I did and learned my lesson the hard way. 10 yr/100,000 mile power train warranty and the dealership is very easy to work with!
