As long as the bearings remain properly sealed, an electric motor will usually run happily for years and years. And if it fails, it's often a simple (though expensive) component to remove and replace.
The problem is entirely with the batteries. The chemistry necessary to contain that much power makes them unstable as shit.
You'd think, but they don't work it that way. There are Teslas on the road that are on their 3rd motor in less than 100k miles. Apparently they're built to be swapped out like modules, with the batteries being more robust. One guy is on his 14th motor and 4th battery, though he's the current record holder for sheer mileage on the car. It seems like it depends a lot on the type of driving you're doing.
