Honda Civic Paint Peeled Near Rear Window - They Refused Warranty Coverage

My 2018 Honda Civic Sedan Elegance Diesel Manual vehicle has paint peeling from the top corner of the rear window, as shown in the attached image. I’ve driven various car brands over the past 20 years, and I’ve never encountered such an issue with any vehicle—especially not with a Japanese brand—within just ten years. I’ve spoken with authorized service centers, but unfortunately, the dealerships stated that no action can be taken under warranty. Dear Honda, a brand we trusted and paid a significant amount of money for based on its quality and reputation, how do you explain this defective and faulty product? Please take responsibility and resolve this issue.
