Corrosion usually affects the body, the suspension, the exhaust, and bolts. The only thing the EV doesn't have is an exhaust system. And compared to the Model 3, which is mostly steel, there are some ICE cars which could do better - for example, the Ford F-150 has had a majority aluminum body for a few years now. Regardless, this isn't a win for the EV column, it's not the powertrain that rots.
