I'm close to 5 years with my Model S. My warranty ran out after just over a year as I passed 50k miles. Nothing expensive so far and I have driven 185k miles now. I have not done a single official service. The extended warranty would have been a total waste because I drive so many miles. I had a few small things that I fixed myself. You can get most parts on eBay now. The real expensive stuff is the drive train and battery. Both have 8 years warranty so no worries there.
Are you on the latest update? I've seen many people complain that newer updates introduce bugs, and they'd prefer an older version.
