Carrier/rack problems of the 2008 Nissan Rogue

I noticed a whinning sound coming from my vehicle. I took it to a mechanic who then reported it was the transmission. I then took my car to a Nissan dealership and they confirmed that it was the cvt transmission (carrier bearing area). I was not aware that there had been issues with the cvt transmissions in Nissan. Nissan had extended the warranty however due to me the consumer not being made aware of the issue that Nissan was having, I didn't know that I should be on the look to see if my car was having issues until I heard the whinning sound. I drive a lot for work, therefore my car has 123,233 miles on it but is very well taken care of and is only 5 years old and has no other issues. I am currently battling with Nissan to have them fix their defective product (cvt transmission). Nissan should be made to correct these defects in their products regardless. Nissan knows of the issue, but from the research I've been doing online they are not taking responsibility for the defective products. Americans should not spend their hard earned money on products that are defective and then companies bailing out. Companies need to take responsibility!.
