rust spots forming on edge of door, 2 acid washes, not gone

Rust spots forming on edge of 4month old door!! They've done two acid washes, but it keeps coming back. Solution...there is none. Detailing department says there is no fix, even if I try to touch up the spots and put a clear coat it will still return.

Let me say the detailing department at the dealership has been FANTASTIC and have gone above and beyond to give fantastic customer service to me. But, they have no solution for this. I can only continue to clean and try and seal it by waxing it by hand, but this is only temporary. What kind of BRAND NEW vehicle already has rust forming? So naturally my concern is that I'm gonna have a rusted out door in two years. Total horse $hit that I paid over $40,000 for this BRAND NEW vehicle, and I have to deal with rust 4months in. Nissan, I'm feeling very ripped off right now!!!!
