Got mine replaced under warranty within my 3Y/60k km period. Not covered past this treshold even under my full extended warranty. Rust came back pretty much just as bad as before during the following winter.
Still need to perform replacement but there is another option on page 2 of this thread which I am giving one last try:
I found this mesh grill material that can be bought already powder coated. Perforated Hexagon Aluminum Grill Mesh Sheets by customcargrills I know it’s been a while but I had this thread in my « Followed Threads » list for when I would grow tired of my rusty grilles… Ordered a sheet of 16x48...

I’m hoping the powder coated aluminum will hold better over time and at least it will not rust…ordered quickly and endes up buying matte black…dont know if gloss black would have been better but mine have had no shine to them for so long I probably wont notice!!
Even my GF comments about the rusty grilles and she doesnt really care about cars!!
