I got a postcard a few months back saying my 2014 Versa had its warranty on the CVT extended to 7 years/84,000 miles. A few questions as I got 72,000 miles on the car. What are the signs that transmission is going bad on this car? I had a couple jerky movements the other day going around a corner after a stop at a stop sign.....may be bad gas or sticky foot pedal. I am going to watch it closely. Also, when the extended warranty says 7 years, does that mean through 2021 or just through 2020....it was not clear on that. Any information appreciated.
