Yeah that Model X may have issues, like an iPhone 1. I think the difference is Tesla has a keen interest in actually fixing them. The factory knows what they screwed up, which cars are affected, and how to address them complimentary at the next service. 100% of cars get fixed.
Porsche is one of the highest quality cars you can buy from a volume manufacturer. The electronics on my 2015 Boxster are not the best, specifically the $2000 active cruise control is completely non functioning (so I have no cruise control at all). The dealer doesn’t know what the PAS feature is, and asked me if I meant PASM or PSM. They don’t know how to fix or reset it, or how to even connect to that particular module. The only way they really can fix it is to order you another car without it. That’s the operating model for these old line auto makers, and people are sick of it.
