I don't think that the average consumer is capable of diagnosing their vehicle. Just the trade terminology alone is a big study. Also, with the complexity of the systems, they interact in so many ways that the proposed repair that the kiosk comes up with, will have a lot of conditions such as," as long as there are no mechanical problems with the engine" that would go along with an electronic problem. My neighbor had the Check Engine light come on in his Buick, and the codes indicated a problem with the mixture being too lean. Well, the head gasket was slowly failing, altering the mixture. the car was not running hot and the electronics, the fuel control, and the ignition system were fine. If this car had been plugged into a computer to dignose the problem, it would not have picked up the head gasket. I think the software would have to also consider that there is a lot of hands on testing that needs to be done. My Ford Explorer had a bad fuel pressure regulator causing the thing to run rich, run like doodoo, and to flag a whole bunch of codes. the test that nailed it was a fuel pressure test. So far, there are no cars with a fuel pressure monitor or sensor. Good idea, but a really difficult application.
