You're certainly free to do so, but at that point you're really arguing about what should and should not be covered. Wear items like brake discs and windshield wipers generally aren't.

Brake rotors often outlive the car they're in. There's no reason not to assume this was due to faulty manufacturing. It's not normal wear and tear, nor something that "just happens" even under high performance track driving.

I've never seen and would never expect a brake rotor to outlive the car! A brake rotor is a regular wear item, you'll replace it many times over the life of a car.

That said, ruined in 2000km is ridiculous, certainly a manufacturing defect.

Warped at 2k probably means they rode the brakes down a mountain, usually a particular driving style.

That's laughable. I have to replace rotors on a semi-regular basis. It's absolutely normal if you drive your car hard even on the street.

He might have a point though. I remember the Nissan service writer telling me that if I went somewhere other than the dealership to get my brakes done, not to let them talk me into getting new rotors without seeing the measurement. Apparently Nissan OEM rotors are fairly thick and have plenty of "margin" before they get down to the wear limit.

He turned out to be right: I only recently replaced the rotors at 150,000 miles whereas at 100,000 miles, my Saturn and Ford had already had at least one rotor replacement. Since a lot of people will get a new car before the old one hits 100k, they may think of rotors as something that never needs replacing.

OTOH: those Nissan rotors were an absolute bitch to get off by that point. I was wearing hearing protection while wailing away at them with a 5lb hammer for at least 10 minutes each before they came loose.

It's a matter of proportion. One does not expect brake disks to wear after 2,000km, that's plain defective. If it were 50,000km I'd agree that's more reasonable for a wear item.

The issue wasn't that the discs were worn down after 2000km it was that they were "warped".

Warping is generally caused not by the rotor warping/bending so much as uneven wear or brake material deposits. This most frequently happens because the system is driven beyond design limits and overheated to the point that the pad material bonds with the rotor. It is also possible that this is a factory related issue and not overheating, but presumably this would have been noted on the test drive, and not after 2,000 km of gas.

If I'm the dealer, I ask myself which is more likely: 1. that my delivery inspection mechanic and the customer failed to notice a braking system issue at the time of sale, or 2. that a customer with a new car took it out and pushed it to the limits?

Exactly, fundamentally it's a piece of cast iron, cracking and other failure modes could be attributable to defects, but warping generally means overheating of the braking system.

I completely get that under normal operation brake disks should not be unusable after 2,000km. My point is simply that it's not expected to be a warranty item, so don't be surprised if the dealer hides behind that.
