The problem with the JD Power report is it includes any kind of problem, and this means it includes customer confusion issues.
This is why cars loaded with tech like the Audi are near the bottom.
Most of us that have a Model 3/Y know first hand that Tesla has some fit/finish and paint issues. Where it bugs some of us like myself, and other people don't care so much.
I was really annoyed with my delivery because they asked me to pick up an obviously defective car. I reluctantly signed for it with the due bill regarding them fixing a bumper alignment issue. It's still of a bit even after they fixed it, but it's not bad.
In terms of fit/finish its worse than any car I've had in recent memory including a 2015 Model S.
It doesn't really bug me because the car is great other wise.
It's just so fast, and so enjoyable to drive. It's not just that, but the entire experience is pretty awesome. Other people have had issues with service which I haven't had. It's been pretty smooth for me since the disaster that was the delivery quality.
Now it's not all rainbow and skittles. If I could pay $1K to a charity to dunk tank the entire autopilot team I would gladly donate that amount.
