My car was delivered with this "feature" particularly on the driver's side. Slow, sometimes noisy, to the point I was worried I'd be stuck with an open window or a broken one. Mobile service ended up replacing the inner window seals and it's both quieter and operates more quickly and smoothly now. It was particularly bad in winter or when wet.
Trust your eyeballs and ears. If it seems wrong it's probably wrong. Nothing Tesla does on these cars from a body and trim perspective is special or different other than sometimes being particularly poorly executed through design or assembly or both. I have a 13 year old car that has better fit and finish in the interior than this thing has brand new, the wipers work better, the buttons and switchgear work better, and the windows work better, that 13 year old BMW is much better screwed together in all respects and everything the driver touches or moves operates more smoothly, more quietly, and more reliably. Don't get me wrong, it all "works" in the Tesla, but it all feels half-baked when you've been used to Toyotas and BMW's and such where the engineering behind all these systems was institutionally excellent for decades before you got the car. Tesla isn't a body and trim company, at least not yet, not when they designed Model X from a clean sheet of paper just 8 years ago, and brought it to production just 6 years ago, when they were barely making any cars at all. I'm willing to forgive that stuff bceause I like the product and I'm an Enjoyer of Weird Cars. But I have no idea how they expect the average vehicle purchaser to put up with this stuff. I guess that's why X is priced where it is, lol, Anyway, end rant.
But the service people are, usually, able to make the car better than new. Everything I've brought to their attention so far has been addressed and then some, so, [fanboy] the car isn't just getting software improvements continuously, it's also finishing its QC checks and getting better every time!
