2018 Nissan Sentra Power Train

My Sentra at around 75mph starts shifting back and forth abnormally between gears. The only thing that releases it is letting go of gas, forcing to drop speed, which also forces a shift to higher gear. You feel a jerk when it's jumping gears, but the RPM arrow also jerks between, started around 30k miles and getting worse.

TL* THE CONTACT OWNS A 2018 NISSAN SENTRA. THE CONTACT STATED THAT WHILE PARKED, THE GEAR SHIFTER FAILED TO SHIFT INTO DRIVE OR ANY OTHER GEARS. THE VEHICLE WAS NOT YET DIAGNOSED NOR REPAIRED. THE DEALER AND MANUFACTURER WERE NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 71,000.

I PURCHASED A NISSAN SENTRA BACK IN JUNE 2020 SO I HAVEN'T HAD IT VERY LONG. IT HAD ROUGHLY ABOUT 52K MILES WHEN I PURCHASED IT AND I PURCHASE IT BECAUSE MY FAMILY HAS HAD INFINITI'S AND NISSAN AND MY DAD WORKS FOR AN INFINITI DEALERSHIP. ALL OF OUR VEHICLES HAVE BEEN VERY RELIABLE. SO WHY WOULD THIS ONE BE ANY DIFFERENT. I RECENTLY HAD AN ISSUE DRIVING THIS VEHICLE WHERE IT JUST STARTED THIS WEIRD JUTTER OR VIBRATION AND THEN THERE WAS LOSE OF POWER/HESITATION AND WOULDN'T GO PAST 45 TO 50 MPH. I LIVE ABOUT 71 MILES AWAY FROM WORK AND HAD A HARD TIME GETTING IT TO WORK. AFTER GETTING OFF WORK I DROPPED MY CAR OFF BY THE CLOSEST NISSAN DEALER TO FIND OUT WHAT WAS GOING ON WITH MY CAR. THE SERVICE ADVISOR CALLED ME BACK TO SAY THAT MY TRANSMISSION WAS DONE AND THAT I NEEDED A NEW ONE. I THEN FOUND OUT THAT THE EXTENDED WARRANTY THAT I PURCHASED FROM THE DEALER EXPIRED ALREADY AND THAT I WOULD HAVE TO PAY FOR A TRANSMISSION IN A CAR THAT I JUST BOUGHT LESS THAN A YEAR AGO. AFTER FURTHER RESEARCH I FOUND WHERE NISSAN HAS A REALLY BAD ISSUE WITH THEIR CVT TRANSMISSIONS AND THAT THERE WAS A RECALL ON THEM. WHEN I ASKED NISSAN DEALER ABOUT IT THEY SAID THAT IT ONLY COVERS UP TO 2017 NISSAN SENTRA. MY DAD DID SOME RESEARCH AND FOUND THAT THERE IS A SERVICE BULLETIN REFERENCE (NTB20-035A) FOR 2018-2019 NISSAN SENTRA; CVT JUDDER. WHEN WE CONTACTED NISSAN CONSUMER AFFAIRS FOR ASSISTANCE THEY SAID THAT MY CAR WASN'T INCLUDED IN THIS, AND THAT THEY WOULDN'T COVER ANYTHING. NISSANS SERVICE BULLETIN SAYS THAT IF ANY OF SEVERAL CODES POPPED UP WHILE DIAGNOSING THE VEHICLE (P2859) REPLACE THE CVT TRANSMISSION. THIS IS MY FIRST VEHICLE PURCHASE ON MY OWN, I'M 23, AND I STILL HAVE TO MAKE THE PAYMENTS ON THIS CAR. I WAS QUOTED A TRANSMISSION REPAIR COST OF 4K TO 5K. NISSAN SHOULD BE RESPONSIBLE FOR THIS ISSUE BEING THAT THEY KNOW OF THE PROBLEM. ANY HELP ON THIS IS GREATLY APPRECIATED.

RPMS ARE GOING UP AND DOWN WHEN MAINTAINING THE SAME SPEED . WE TOOK IT BACK TO THE DEALERSHIP AT 9000 MILES AND THEY TOLD US IT'S A SPECIAL TRANSMISSION.BELT DRIVEN NOT GEAR DRIVEN. WE TOOK IT BACK A FEW MORE TIMES AND FINALLY WE TOOK IT TO MIDAS AND THEY TOLD US TO TAKE IT TO DEALERSHIP FOR THE TRANSMISSION PROBLEM AFTER THEY DROVE IT AND NOTICED RPMS GOING UP AND DOWN .

STOPPED GOING FORWARD WHEN AT TRAFFIC LIGHT WILL ONLY GO IN REVERSE. DEALERSHIP SAYS WARRANTY IS UP AND IT WILL COST 4000$ TO FIX. I AM CONFUSED AS TO HOW A CAR THAT WAS BOUGHT 4/20/2018 HAS THE NEED FOR THE TRANSMISSIOM TO BE REPLACED. THIS CAR HAS HAD REGULAR MAINTENANCE AND I DO NOT BELIEVE AFTER PAYING 479.09 A MONTH FOR THE PAST 23 MONTHS I SHOULD BE SPENDING AN ADDITIONAL 4000$

CVT FAILED AT 65000 MILES. EXTENDED WARRANTY REPLACED IT. VEHICLE WAS VERY DANGEROUS TO DRIVE AS IT WAS JERKING, SHUDDERING, REFUSING TO ACCELERATE, AND STALLED TWICE.

THE TRANSMISSION IS GOING OUT I WAS ONLY ABLE TO USE REVERSE, MY CAR HAS 46000 MILES I HAVE NEVER BEEN LATE ON CHANGING MY OIL AND GETTING THE CAR SERVICED, WOULD NOT RECOMMEND BUYING A SENTRA

TRANSMISSION OVER HEATS. TRANSMISSION HAS A LOUD NOISE AND DRAGS SINCE 60,000 MILES
