Uninformed speculation: they need oil changes, but aren’t in the regular service so it will break down, causing costly repairs or forcing you to buy a new one. The planned obsolescence is baked right in.
The motors are sealed and will last long beyond drivetrain warranty periods (which is 8 years, 120k miles on Model 3/Y). Battery packs do have a coolant that is intended to last the life of the vehicle, though I’ve heard of it being drained/replaced after maintenance where someone had failed valves in the coolant system.
ICE vehicles break down far faster, requiring loads more maintenance and parts replacement over their lives, even when properly maintained. More moving parts, more friction, more points of failure.
My man, change your drivetrain oil. Call me old fashioned but vehicles should last longer than 8 years. This “lifetime transmission” stuff is hogwash. I have a 5 year old ICE car that I plan on changing it’s transmission oil and filter…in about 3 years.
Your drivetrain is made out of actual materials. Not some marvel movie space metal. It will shed some metal into the oil when it moves. You don’t want to drive around with grit soap for lube.
Dude, this is utterly ridiculous nonsense and no one should be having their Tesla motor drive units cracked open to change lubricants. Not only does it void the 120k mile warranty, but it proves you have no experience with them.
You may as well be telling me to have my rear diff rebuilt on an MX-5 after 10,000 miles.
