Why the downvotes? I'm serious. If cars start lasting 600k+ miles and are shared by multiple drivers and families, car companies will ‘need’ to recoup their losses. Expect prices of car components (the stuff that wears out) to skyrocket, and patent litigation to get rid of the after-market/3rd-party compatible components.

I don't think you even have to imagine any malice or profit-protection on the part of the manufacturer to see that.

The simple fact that current cheaper parts are going to be replaced with higher-quality parts is going to cause a corresponding rise in maintenance and replacement costs.
