I tried that AI diagnosis for my 15 old Ford C MAx too, however with a diagnostic problem the issue is unless you've got the ground truth, there's simply no way to verify any tool / human with a metric that you can compare and decide on future tasks.

The AI might be very good at diagnosing all minor issues, but might not lead to a successful repair, whereas human mechanics are extremely good on 80% of major issues that's not the ground truth, but will lead to successful repairs (that might not address the root but simply patch it). So it comes down to manage expectation / outcomes.
