> I was under the impression that stainless steel didn't rust, albeit obviously depending upon the grade. Like my kitchen sink is made of stainless steel and doesn't have a clearcoat. Has never rusted and won't over decades. Is your kitchen sink installed outside where it can rain, snow, etc?

Are you thinking a sink doesn't get exposed to water?

  A kitchen sink isn't usually exposed to road salt. It's also probably made with a different grade of stainless steel. (As others have noted, it looks like Tesla intentionally chose a less-resistant alloy for price reasons. This would be consistent with other consumer complaints about their build quality.)

  To the extent that a truck parked outside does? No, not really. Consider the that a kitchen is typically climate controlled so lower RH means the water left in the sink will evaporate quickly. It’s not just water either, being outside exposed material to sunlight, dirt, dust, acid rain, temperature extremes, road salt, etc.

Are you aware that kitchen sinks are typically subject to frequent and prolonged encounters with water and other substances?

  A kitchen is a climate controlled space. The water left in a sink evaporates quickly. There is no acid rain or road salt in a kitchen, etc. Being outside is damaging to materials, moreso than just water exposure.

    The average kitchen sink sees a far more challenging environment than you seem to believe. My kitchen sink sees acids, bases, salts of all sorts, and just about every manner of abuse. Boiling, freezing, and rapid changes in between. It has nothing to do with environment. As others have mentioned, most kitchen sinks, like good "silverware", have a higher chromium content. The CT seems to have a low grade SS. The (in)famous Delorean clearly used a better grade of stainless steel. There were no problems with Deloreans rusting, with people having said vehicles many decades later will zero body rust. That was specifically the #1 noted feature of the car.

Boiling, freezing, and rapid changes in between. Does your sink get coated in salt for weeks at a time? In areas where road salt is used, cars certainly do. Cars parked outside will often still be wet after a nighttime rain, while water in a climate controlled kitchen sink rapidly evaporates. If your kitchen sink is still wet the morning after washing dishes, you’ve got bigger (mold) problems to deal with. Even 316 ‘marine grade’ stainless will pit and rust, given enough time outside. I’ve seen it plenty, metal NEMA 4X enclosures rated for outdoor use are made from 304/316 SS, and those eventually rust.

Sinks are made from a more corrosion-resistant alloy than the one used on the Cybertruck.
