At what miles would a new car breakdown if you did 0 maintenance?

2019 Honda CR-V.

It's totally impossible to say. Depends a lot on how it is driven, the climate it is in, the road conditions and a number of other things.

It is STUPID to think about that. Maintain your vehicle. You could DIE or cause the DEATHS of other people driving with worn tires.

Impossible to say.

The oil would be worthless by 20,000 but even then it may not die. I was surprised how many miles I got out of crs when I said that I was not going to spend another dime on them.

Leased a car and did no maintenance at all and it was fine at 80,000 miles. Don't know what happened after that nor do I care. Not my problem!

I know of someone that did that… Never did an oil change on a brand new car. The car made it approx 29K km ( ~18K miles ) before the engine seized. The engine oil had solidified

Oil and filter changes need to be done every 3,000 miles if running regular motor oil and every 5,000 miles if running synthetic oil.
Lease a car if you're not going to take care of it.

What a stupid question.

With zero maintenance any car, regardless of brand will break down as soon as the oil no longer does its job. About 50,000 miles.

Somewhere between 0 and 250,000 miles.

It's really depends on how bad you abused it.
