Hatchback/liftgate Support Device problems of the 2015 Honda Odyssey

On December 28th we unloaded the back of our minivan and closed the liftgate and everything was fine. The next morning we came out and there was a 5"x5" section of the paint just peeled off and laying on the ground it peeled all the way down to the base color (perhaps primer layer). Realizing this was clearly a defect we quickly did our research and realized this is a very common issue with Honda vehicles, specifially Odyssey and commonly in the white pearl color. Brought the car to the dealer to have them look at it. They quickly asked if I wanted and estimate. I explainted that I was aware this was a common defect at which point they acknowledged it is an issue with the primer and they would take images and get in touch with Honda corp. Honda corp said my VIN did not qualify for their warranty extension as that only applies to 2012-2014 models. My car was delived in 2014, but was the 2015 model. They knowingly have sold me a defective product and they are refusing to take ownership of this widespread issue. This section is clearly going to spread. The cases that are more advanced than mine are ridiculous.
