NHTSA Complaint #11651401 — 2017 NISSAN SENTRA

I was driving on the highway and saw that my RPM was fluctuating a lot even though on cruise control, it was losing its power. It started slowing down and even though cruise control was off, I was indeed in drive and not neutral. when I fully pressed the gas it did absolutely nothing. I was close to home 10 minutes so I had to just put emergency lights on and keep going but at the stop signs and lights sometimes it would stop completely and get stuck at 0 even though i was pressing the gas pedal all the way. Once I was going - it let me go, seemed like it allowed it. Then but never past 25 But anytime I slowed it almost shut off or did shut off. This is a safety issue since I am not able to drive the speed limit. I risk getting rear ended. There were no warning messages on my dash when this happened. I took the car to a mechanic, who stated I needed a new transmission. I bought a transmission and the mechanic replaced it. It was fine for a couple days then started having the same problem. I took it to Nissan to get it diagnosed and they stated that it was due to the transmission. Nissan stated the recall expired so they could not help me
