As a pretty bad home mechanic, I want to agree with you. The DEF in my BMW went bad (urea has a short life span) and BMW charged me out the wazoo to reset the computer auto-shutdown feature (you get 200 miles to fix it or it won't start again) and I had no other choice, since I can't do it myself. I can flush the DEF, but I can't reset the computer without their tools. I don't believe even iCarly can un-flag the error.
On the other hand, my political beliefs tend to say that government exists to protect you from me and me from you, and the emissions of your vehicles falls into that category. So maybe there's an argument to be made that at least certain parts should be locked down?
(for the record, I don't think any of it should be for the sake of competition and home repair, I'm asking for the sake of conversation / devil's advocate)
