Not just in Norway, but right here in the U.S. of A. Ordinary Tesla service almost always happens much faster, but Tesla service centers don't handle body shop repairs. Those are handled by outside contractors, and there are reports from some body shops of waiting on parts for weeks or -- in some (hopefully rare, isolated) cases -- for months. Tesla claims to be addressing that problem, but obviously they haven't solved the problem everywhere, at least not yet.
See the InsideEVs news article: "
Tesla To Apply 'Brute Force' To Solve Body Shop Wait Issues, 300 Additional Body Shops Added Soon"
Tesla is having growing pains. That's what happens when you grow rapidly. It's one factor which car buyers need to consider. Tesla's very rapid rate of growth does have consequences, both good and bad; and car buyers should consider that situation before buying.
But let's put this into context. Despite the probably rare cases of Tesla cars spending unreasonably long periods in the shop waiting for parts, Tesla's Model S tops the list of
Consumer Reports' annual survey for customer satisfaction
every year. And the Model X isn't far behind; it's in the top ten.

@David Green: You need to keep reminding us about how you have forgotten more about the auto industry than I will ever learn. For some reason, I keep forgetting that "fact".
