My mom’s Chevy had a similar looking paint “cancer”. It’s usually something stupid with one of the under layer treatments .. like that’s where the clamp was on the robotic holder during the process so that little area has no adhesion promoter. Then the elements (rain, salt, whatever) gets at it and the paint peels off. But will they change their manufacturing process …. NOPE. They’d rather gamble on all the people that won’t seek warranty work because they think it must be their fault.
