It’s generally not necessary to replace cars every 5 years due to part shortage. For years the OEM (original equipment manufacturer) replacement parts fill into the wholesale and retail channels. If the manufacturer stops offering the part, there are still parts in those channels to meet demand, sometimes for many more years to come. The manufacturer may keep offering parts beyond the requirement, too. Parts can be profitable, and service can be a big part of dealer revenue. Dealers who make money on service put pressure on the manufacturer to keep parts available. Physical parts are also pretty easy to copy, so if demand persists beyond the availability of OEM parts, you can often get aftermarket parts. There is also a channel of junkyards and enthusiasts who hoard used parts with life still left in them. I’ve got a couple friends who like old vehicles and they are able to get parts for trucks that are nearing 40 years old. I own a car that just turned 12 and have never had the slightest problem getting parts for it, even OEM.
