Try with the dealership first. They would argue that this is the result of a rock chip and you should have taken care of it soon after the rock chip. Although there is no way to tell if this happened before or after the sales, it's probably after the sales because you would have noticed it earlier. Maybe there will handle it as a goodwill gesture.
If no luck, you can always try MB Canada 1-800-387-0100.
As for the questioned if this can be a DIY, it all depends on the size and the location of the rust. Main question is would it show after the DIY? To fix it properly would involve sanding, primer, spray paint the whole panel.
If you decide to get this professional repaired, go to Western MB. They do great work.
