NHTSA Complaint #11630703 — 2016 NISSAN SENTRA

My 2016 Nissan Sentra malfunctioned while driving on the Highway three separate times. The car suddenly lost its ability to accelerate and seemed to power down while becoming more difficult to steer. It seemed to start shuddering and I thought it may have been a front end flat tire. After pulling off the road and putting the car in park, when I waited a minute or two, I placed the car in drive and there was no problem until a month later and it hppended again except on an interstate while driving over a long bridge. Two different Nissan dealers could not diagnose any issues and kind of threw up theirs hands with no suggestions except to bring it in again if it happens once more. The auto has become hazardous to drive for two seniors, and no one seems to be able to diagnose or fix the issues. I read online about Nissan CVT transmission recalls for these Sentras, but never received any recall notifications.
