Automatic Transmission Control Module problems of the 2010 Nissan Rogue

2010 Nissan Rogue sw pre-owned certified on 2/24/2012; mileage: 13,403. Purchased security+plus service warranty. The summer of 2014 Rogue started a whining noise going up hills or under a light load. There was no other indication from the vehicle that it was under distress, no warning lights appeared etc. Dealership mechanic test drove and confirmed the cvt was failing. 6/13/2014; mileage 44228 per warranty, installed: "1-transaxle assy; 1-trans exchange expense; 5- ns-2 cvt tranmi; 1tranmission CO; 1 cooler kit-auto. " "certified concern, per tech line replaced cvt transmission assembly, programmed tcm, installed transmission cooler, operates per design. " the cvt was flushed and cleaned on 6/06/2018 at 78,882 by same dealership. Miles since new cvt was replaced 44228 - 78882 = 34654 June 24, 2021 upon returning from a trip the car was not shifting properly. At starting of an intersection the voc light flashes and came on, and the car hardly would go across the intersection with the gas pedal pushed to floor. There were times gear shifting would rev and not shift smoothly. It was dangerous doing only 55mph in a 75 mph on I-10 returning. On July 22, 2021; mileage 92762; took to dealership for digonostic; they reported: "caused by check codes and a/b counts no code present. Transmission has b counts recommend transmission replacement. " "cvt assembly $4890; front lower control arms if done at time of cvt $650 & drive belt $180. ". And, of course, they informed me that the warranty expired 1 year to the month. However,it is my understanding that 2010 Rogue were given an extended 10 year warranty/150k. My warrenty book indicates differently. I believe Nissan's warranty on my specific vehicle is misleading and needs reviewed. And may be considered fraudelant. A 2010 Nissan Rogue has less than 94,000 miles 1 cvt replaced prematurely now requiring another new cvt transmission replaced. North America Nissan denied asst beyond warranty.
