The area to the left of the headrest is definitely not a "wear" area, as nothing ever touches it, and the surrounding area is pristine. The right front corner is definitely subject to wear, but again the area surrounding it is pristine. The stitch is visibly broken. This, the only issue in that area, and a broken stitch around a pristine area is not usually a wear issue. The two defects together show a problem with quality of manufacture, and not wear and tear. I would have gone to Tesla, had the area repaired under warranty, and if they claimed otherwise, take them to small claims court. No judge would ever refuse this evidence as covered under Tesla's transferable new car warranty. Tesla is leading you on. Don't cave. The only problem I have is that a good interior shop may be able to correct these defects quickly at a reasonable cost by restitching these areas as the manufacturer should have done, possibly without removing anything.
