Sensors and crumple zones are part of it. But for the Telluride, some of the issue as well is that the OEM parts are often available only for gross assemblies. So where as historically you could get discrete parts for other manufacturers, for KIA they often only have big pre-assembled assemblies available. That was the case for the alternator which played a few different roles and could only be replaced en-masse. Headlights are another area where any damage requires an entirely new assembly.

The approach makes repairability really, really expensive.
