Hello! I got a brand new Nissan Sentra 2013 in January 2014. Had no problems with the car till a few months ago. Car would suddenly start to loose speed, then it would “jerk” once and gains the speed back. Exp. – i was driving 35mph on a straight road and suddenly speed dropped from 35 to 20mph in about 2-3 seconds, then after a couple of seconds it jerked and started to gain the speed back. As of now car has 24,000, I do regular maintenance every 3 months with Nissan dealership, drive on short distances only. Thanks
you should still have powertrain warranty on your Sentra, worth a shot to ask dealer for diagnostics?
