Come off it - it is a seat, it's going to get crumpled. This kind of desire for perfection in everything creates enormous amounts of waste due to rejected products. This kind of thing is why the supermarkets reject wonky veg. Suck it up and sit on it.
I’ve got white seats in mine and from new I had a noticeable crease. I probably wouldn’t have bothered for a couple of small ones.
I’ve been having issues getting them fixed. I get the impression that it’s not always an easy process under warranty if it’s not reported with low mileage and has to be authorised outside of the UK. However, I reported mine when they were less than a day old.
Are Tesla owners getting a bit carried away with these "quality" issues? This is what my Porsche seat looked like after 10k miles - see the crease on the driver's side bolster (I weigh 78 kg by the way). Our leather sofas have some creases on them too. That's just how it is with soft squashy surfaces! Tesla vegan seats are actually among the best for not creasing very much. Leather seats tend to be a lot worse, but it's not something I would tend to complain about unless the stitching fell apart or the surface starting cracking.
