Thought I would share today's experience with a set of rotors that failed. I was expecting a seized caliper as rotor was rusty and brake pads were cleaning corrosion off other 3. After tearing it down this separation from the fins rusting away. Rotors were brand new a little over 2 years ago. O Reillys replaced them under warranty even though it said 2 year warranty. Said they have never seen this before. Last winter made a trip to visit family in snowstorm but washed it within 1 week of driving in the slushy stuff

Even Chinese rotors don't rust that bad. Maybe N. Korean rotors?
I didn't think they could get that bad in Kentucky 
I'd expect that to be more likely in New England, Minnesota, or Canada, but not Kentucky
This is why coated rotors are awesome

Dear Lord have mercy. What in Putin’s name is that?
WOW I cannot believe they are only two year olds. I've seen 50 year old rotors in GA that looked better..
Somehow I don't think that was a planned alloy... Some aluminum melted into the furnace? Seems like some galvanic corrosion or something? Usually cast iron is pretty rust resistant even in the rust belt.
Wow.. like everyone else has said.. just wow.. But.. I live in Michigan, so here is where salt is thrown around in crazy amounts during the winter..and I haven't had a rotor/disc die that early of a death, ever! Usually can get about 4-5 years out before they are very rusted but not falling apart.. Glad to hear you got them to replace them!
That's crazy.
I had a seized caliper on sons Forte. I had to get what was available quick to get back on road. New caliper and Rotor from Autozone uncoated. I had the Raybestos Element coated ones on there (but either hose or caliper failed anyway). Pictures are ~2 year old coated caliper/rotor and then the surface rusting 6 day old one.

That is what crappy rotor, I hope it was at least very cheap.
Wow that's bad. I'm wondering if O'Reilly faced a covid era supply chain problem and sourced whatever they could find.
Depending on the area and weather, automobiles can rust pretty bad in KY, at least in my area where they salt the roads if it MIGHT snow, then if it doesn't snow much, that salty slush is super concentrated and more of it stays on the road instead of being plowed or melting/flushed off the road.
This statement is confusing:
There are two rotors pictured, neither looking like they had any pad contact from being driven recently.

Something must be terribly wrong with that metallurgy.
I've replaced 25 year old rotors that had ~250K miles on them that looked way better than those rotors.
