To be fair, cars are becoming less and less serviceable.
I had a light bulb that died on my car, and tried to change it myself. How hard could that be?
Turns out the light bulb is so buried under the engine I ended up giving up and bringing it to the shop. And often even independent shops can no longer service cars, you have to bring it to your maker's dealership because only they have the proprietary tooling to fix it.
