I think it would be fair to say that all manufacturers have their own fair share of quality issues, but unlike other manufacturers, for whatever reason (possibly too rushed, possibly arrogance due to market position, possibly a bit of both?), they don't seem to do much to fix the problems before the customer takes possession. A PDI seems to be something Tesla pay very little attention to if they do one at all.
I have always been of the attitude that its not that a problem has arisen, it is how that problem is rectified. Unfortunately, Tesla can fall very short here. At times it is almost (or actually is) impossible to communicate with them and when you do, you can ask 5 different people the same question and get 5 different wrong answers. For some reason, their staff do not know how to say "I do not know" so you get some made up story, and at other times, it transpires that you have been blatantly lied to. I think some of this comes back to the attitude that Tesla are doing us a favour rather than us being a customer that allows Tesla to flourish. I must admit, if Tesla were not the only vehicle manufacturer who sold vehicles that met my requirements, I would have walked several times. There are some great staff in Tesla, but there also seem to be a few really bad staff, systems and processes that seem to cause unwarranted issues.
Finally, the car is always evolving, so ownership experience changes on a month by month basis. It is not unusual for big backward steps to be taken or promises to become forgotten. I often wonder how many of the promised FSD features have now been deleted from the product backlog.
I'm sure much of this is down to rushed schedules (certainly less busy collection centres seem to fair better than more busy ones), but unfortunately, that is used often as a valid excuse.
imho Driving experience is good, not so for the ownership experience.
ymmv.
