It's bullshit to equate satisfaction survey results with quality. So you don't get all offended, I'll use Porsche as an example.
Porsche cars, like every other manufacturer out there, can exhibit reliability problems. In some cases, the problems can be really pretty bad and fairly prevalent. And yet Porsche usually ranks pretty highly in customer satisfaction surveys due, in part, to brand loyalty. And in part, because of the feelings evoked by driving the car.
I'm a perfect example. I flat out love my 911. Love. It. But my car isn't perfectly reliable and it has flaws (e.g. the manual gearbox can be notchy at times, especially when cold and the sound system is meh). Doesn't matter to me. Nor does these issues seem to matter much to a majority of 911 owners. My subjective satisfaction level is like 11 out of 10. I'm so happy with it, I'm in the market for a second, more extreme 911.
So I would imagine the same is true for Teslas. Or Jeeps (which are notoriously unreliable). Despite the reliability issues and fit and finish issues, the owners still really like them.
Satisfaction and reliability just don't correlate very well, at least with certain brands. You'd think they would. But they don't.
I've always said the same of Audis. They can be pretty glitchy, but when it happens the service is almost always impeccable and the cars are, IMO, tops in their classes because the driving experience is just so good.
