Fail To Accelerate problems of the 2017 Nissan Altima

For the past two weeks I noticed that my vehicle started loosing power at highway speeds randomly. There were times I depressed the accelerator and a significant delay took place with the car speeding up. Yesterday 10/09/2020 while driving home from work it happened again. The car failed to accelerate at highway speeds and began skipping between gears. After getting off my exit for home, I came to a complete stop and waited for the light to turn green. I depressed the accelerator and nothing happened for about 5 seconds. The car finally drove forward and I slowly drove the remaining 4 miles home with my hazard lights on. I made an appointment with the grainger Nissan dealer in garden city, georgia for today at 9:00 am. I explained the situation to them and was informed that it would take a few days to diagnose the problem. A couple hours later I got a call from the advisor stating that my cars transmission needed to be replaced for $3800. I asked if this was a common issue with Nissan Altima's that have 90k miles on them. He stated that there are some vehicles that have been identified with this issue by the manufacturer and others are not covered by any warranty. He stated that during production they labeled some vehicles by the VIN number with the issue and would repair those vehicles at no cost to owner. However my vehicle did not receive that label. My concern is if they are aware of the failure with their transmission how do they determine which cars they will fix and which ones they will not. What are the criteria to meet eligibility for repair their defective product?.
