Nothing all that unusual about reaching 400K miles. I've done that in gasoline-powered cars.

Note that the battery pack in that car was replaced at 250K miles, the equivalent in cost of replacing the entire engine and drivetrain in a conventional gasoline-powered vehicle if it had to be paid out of pocket. (Probably a lot more expensive than that.) Many conventional vehicles can surpass that mileage without such serious repairs. I've done it myself time and time again over the years.

Warranty costs are figured into the purchase price of the car. If you want to pay as much for a Toyota as a Tesla I'm sure they would be able to include an unlimited mileage powertrain warranty.

All-in-all not very remarkable achievement and it does not change my opinion that if someone gave me a Tesla I would give it back.

There is no free lunch.  The “unlimited mileage” warranty is paid upfront by the buyer as part of the purchase price of the vehicle (so basically baked in).

It strikes me as being scripted and rehearsed to promote Tesla. Honestly Dudes glasses & hat look like a prop to me, but I'm very cynical. I could be completely wrong. It sure wouldn't be the first time and it won't be the last. 😮 

He replaced tons of parts that would likely have cost more than a lot of nice cars brand new, That is not impressive at all to me.

I have seen plenty of 2nd and 3rd gen prius going over 500k miles without any major issues, and on the original battery!

If I throw enough money at a kia, I can make it to 400k miles too!

By the way, I have never had a warranty.

This example is probably better built. It could be already the present but I do not expect it. Maybe some prototypes will be more reliable to attract people. When masses buy them, the reliability will probably go back down. Marketing strategy, I guess.

Please forgive me but I watched that video and think the whole thing was phony made up BS

Unlimited mileage but only a certain number of years?
