I can’t speak for the OP, but a “rotor” can mean the brake rotor on a disc brake, which can warp due to excessive use/heat. They are common on most cars, and usually need to be “turned” (ie. machined to be flat) when they are out of tolerance.

Throwaway economy: I haven't been able to find anyone to turn a rotor in ~10 years, but Amazon will bring me brand new ones tomorrow.

Sure, quality has gone down, but, well, that's why it's not worth turning them anyway.

I’ve owned some Hondas recently where the rotors noticeably warped after several years (maybe since the cars have such good longevity?).

It probably strongly depends on driving styles. I also trust OEM metallurgy far more than anything you can purchase off Amazon.

I've got a 2012 Toyota with regenerative brakes that's had its rotors turned twice (by independent shops) after they've become rusty/noisy around every 5 years or so. But it still has all the original rotors and pads! The mechanics wouldn't replace them since there wasn't enough wear. It's almost bizarre at this point. Maybe in 2027?
