Rust on the ASX

Hello guys! Unfortunately I had to find out that the drive shafts and the exhaust are rusty on my six weeks new ASX! Is something like this normal, or is it due to poor quality? A Dekra employee told me that the drive shafts were probably not painted, that was bad! Did someone have to have similar experiences? Has Mitsubishi saved there? Some screws on the exhaust system together with mounting brackets are totally rusty, as if they were already years old. before a MX-5, the exhaust system was still ok after 10 years. Does anyone have a tip for me? Thanks and greeting Bulbrok!
