Just bought 2013 Nissan Sentra, transmission problem the first month and replaced. Car decelerated on Mass Pike immediately to complete stop in middle of highway in traffic, had to jump out and run to side of road. It was replaced, 3 weeks later same thing happens, on highway and car comes to complete stop in the middle of highway with oncoming traffic. Car is dead again and in shop, I am afraid to take it back. I got online and see all the same complaints. Are they waiting for a death? I am waiting to hear what they say is wrong then will call car dealership.
