Automatic Transmission Torque Converter problems of the 2011 Nissan Frontier

I was driving my truck as normal when I heard a chatter from the gear shift. . I lost all power in the low gears and it would take 45 seconds to get to 60 mph. I drove it a short way like that and the check engine light came on. I parked my truck for a few hours an when I went to drive it back home the problem seemed to be fixed and was driving normal. I started my drive home and after 50 miles I could smell something burning so I started to get over to the side of the road. At that point I lost all power and the truck was dead. It would not start and I had to call for a tow truck to get my family and I home. I was watching the temperature and oil pressure gauges on the dash and they were normal so it was a surprise to me when I took it to the mechanic and he told me the problem happened because the lower part of the radiator that cools the transmission cracked leaking radiator fluid into the transmission. This caused all the parts to swell up causing the computer to burn up, sensors to fail. I spent over $4000 on parts and labor to get this fixed. That included a rebuild kit, band,piston, exchange rebuilt torque converter, new valve assembly, radiator, radiator cap, front pump bushing, crank sensor,revolution sensor, and all the labor. There were known issues of this exact problem and earlier models up to 2010. There was a class action lawsuit about it. Well the problem is still there on the 2011 model. I should be reimbursed for all my cost since Nissan knew about this issue and still made a inferior product the following year. They did nothing to address this engineering flaw even though they had complete knowledge of the problem. This could of been avoided by having a separate transmission cooler . Nissan was negligent for letting this design go to market when they already knew it was an issue. It should of been resolved on the 2011 but it wasn't,.
