Rust all over the doors and drawers

Fridge is 3 years old purchased when I renovated the kitchen. I cleaned often with SSQQ cleaner. Now one door has an even haze of rust and spots and pitting have appeared on both. Similar pitting on the drawer front of my gas range and beginning on dishwasher door. I see these complaints have been filed for several years. I wish I had seen them when I was shopping. Is there a class action I can join? I am retired on a fixed income and am furious about this. I guess I will be starting the arduous process of seeking recourse under the extended warranty.
