Have you ever fixed an older combustion engine vehicle? You watch a youtube video and a few hours later, you can, in most cases, at least get the car to a state so you can drive it to a mechanic. On modern combustion engine vehicles this is still possible, although a bit more difficult.
Uhhh, EVs? No way you’re fixing anything in there.
Most EV components you’d need to replace are the same as in an ICE. There’s way less that needs to be done on an EV. The expensive bit has an 8 year warranty on most EVs including Tesla.
Tesla cars can only be serviced by Tesla mechanics with Tesla parts, and they have software locks.
