NHTSA Complaint #11610654 — 2017 NISSAN ROGUE

The transmission on my 2017 Nissan Rogue is failing. I was driving from Queens, New York towards my home in New Jersey with my 10 year old nephew. There was a lot of stop and go traffic. Once I got into Manhattan, I noticed my car was having a hard time accelerating. The RPMs would go up to 4 but my car wouldn't go pass 40 miles on the speedometer. I pulled over to the side and turned off and turned on my car to try to reset it. It worked and I was able to continue driving. However, when I got to the Lincoln Tunnel entrance, the same issue was happening. Because it was stop and go traffic. I decided to again turn off and turn on my car. This time, when I tried turning it on, the car wouldn't turn on. I attempted it again and on the 3rd try, I was able to get it started, the check engine light came on, but the car drove fine until I got home. I took it to the dealership the next day, and they told me the transmission is failing and it would cost me $6200 to replace it. I asked if there was a recall on it, they said there was but my warranty expired. I thought the warranty was extended for another 10 years. Is this not the case? I'm confused by what I'm reading online. Is my dealership required to replace my transmission at no cost? This is a pretty dangerous situation as I don't feel safe driving my car anymore, it was especially scary since I had my nephew with me.
