Tesla at 1.2M miles, only took 14 motors & 4 batteries.

Yeah, it's a Tesla problem. Toyota EV motors for example last hundreds of thousands of miles.

Which Toyota EVs exactly?? Or do you mean hybrids which are an entirely different beast and design?

And what is the power density of the motor and drive? Highly likely the denser one will be the shorter lived unit.

Motors should not be a wear item. Industrial motors frequently last forever unless abused and only bearings are replaced if brushless.

That’s not true at all. An industrial motor compared to a vehicle traction motor is like comparing an I beam to a toothbrush. Sure they’re long and flat, and both deflect with use, but that’s about it. Everything from bearing design to cooling design to insulation is different.

Most of their cars aren't high quality. They use non-automotive rated hardware often.

What exactly is automotive rated? What standard specifically?

I remember hearing that Honda / Toyota etc only design their engines and transmissions to last 250k miles. If you get more than that great, but nobody design their consumer stuff to last 1M miles like long haul trucks.

Even 250k miles is an incredibly long ownership for most folks. And those that put enough mileage per year on a vehicle for it to be fast, put a lot of non-wearing steady state mileage.

Reality is that if some manufacturers are designing for 150k, and some for 250k, the average owner that drives 12k miles a year and is tired of their car after 10 years is going to be way closer to the design limits of the 150k car, and statistically be likelier to have failures of items, as compared to the 250k design vehicle.

This 100%. I've only had one vehicle I took to over 100k miles and I had it for 8 years. I usually keep a car 5-6 years. I'm planning to do that longer with the Teslas just because of the drivetrain warranties. I'm just losing my urge to tinker with things and the simplicity of an EV with a warranty to cover the big stuff for 100k miles.

I'm pretty gentle on vehicles and I've had cars that were 15 years old that still looked brand new, so for me the involved materials at the touch points have to be pretty poor for them to show wear with me that's a huge turnoff if it does become an issue. Painted plastics kind of suck.

Well, the reality is that every modern EV battery pack will outlast a Kia/Hyundai ICE and these electric motors are simply flawed. Overall a non-issue.
