I've been paying particularly close attention to shortages along these lines. The chips and special parts going into our logistics system are at the root of making everything it transports possible. We don't even have the fancy AI trucks yet and yet the US runs on a network of semis and fleet trucks that are rapidly running out of replacement parts. The breakdowns in repair/production capacity are so scattershot that there's no telling what the transport delay will impact next. Those chips compete for production space with every other kind of vehicular computer system, let alone other kinds of chips a micorprocessor plant could retool to make.

Technically, you can implement versions the core features with analog/mechanical solutions, though they won't work as well and will require more parts. Most importantly, modern cars have been designed with the expectation of central control by a chip, so manufacturers would need to do a complete redesign + test for an old-school analog car that also passes modern safety and emissions standards.
