Toyota Avensis Paint Is Chipping, Flaking Away Piece By Piece

My 2013 Toyota Avensis has many paint chips. I told Toyota Turkiye, but they won't take responsibility. I think the peeling paint is not my fault, and I want to find a solution to fix it. The paint is chipped, which makes it look bad and lowers its value, doing nothing that can cause this. I park it, find it sometime later or notice it that it's flaking away.... It's sad to see my car lose value because of something I can't control. My old gray 2011 Avensis didn't have any paint problems, even after using thinner. It's confusing why my current car is having issues. Yet Toyota Türkiye is not acknowledging or fixing this issue. I expected better help and responsibility as a loyal customer. Want to maintain its worth and quality, so please take this seriously, get back to me immediately.
