Cars have service schedules, but they aren’t legally enforceable like they are on aircraft to keep the aircraft certified for flight, nor do cars have to keep maintenance records - and with good reason.
Serviceability is also a design feature and philosophy in aerospace, especially in engines, that is sold as a feature of the product and it’s life cycle for “up time”. I don’t believe that is very much of a consideration in automotive.
Best example I can give on cars is the need to replace timing belts. Known routine service repair. The expense of having this done is incredibly high (on transverse engines) since it usually involves dropping and twisting the engine somewhat so the covers can even be removed. I personally consider this as a known design defect since they know it has to be done (service manual) and do nothing to mitigate it - why should they since they hope to get a lot business pushed back to there service departments. It is what it is almost all cars have this problem.
Looking on Craigslist at some cars, had to laugh at this one, the person I’m sure (or hope) meant miles per gallon. Then again, maybe it’s accurate.
