I did not replace it with another car. I never had any CVT problems. The part of the Nissan that bothered me the most were the batteries. The dealership had to put three in before they found one that was reliable.
The problem is that it had a CVT with no other option.
Were your batteries replaced under warranty? If so good, if not, I would have gone elsewhere. My 2002 SE battery lasted 10 years+ I just decided to change it because I was afraid, it gave me no problems. I think it was a Panasonic
