While I cannot speak for all electric cars, I do know that the Tesla Model 3 does not have a scheduled coolant or lubricant replacement.
There is a lubricant in the car’s electric motor/fixed-ratio drive mechanism. It’s a strange mixture coolant/lubricant, but it’s sealed for life. It was blue in color, but it didn’t look oily.
The bottom line is that you don’t need to worry about the presence of any lubricant.
I believe that older Tesla’s, the Model S/X and the original Roadster, need to be maintained with fluids. But not the latest.
My Model 3’s recommended service interval is “Never”.
