Many times on my more expensive gadgets(side by side, tractor, cars.) the support and service has been lackluster. The first time I had to switch my backhoe for my box grader I said wtf? I have to do a half hour job of switching out this equipment? My Ford back hatch isnt closing in a properly aligned position so I turned it into warranty service before I reached 36k miles. Turns out nothings been done and now I'm over miles. When I paid for the extra service for my side by side, the first time they picked it up they "cleaned" it with a pressure washer blowing off my decals. Returning it in this condition without mentioning it. And it was a constant fight to get it fixed.
Long story short, Stern seems to be willing and able to fix and help their customers. The dried wax seems like you were looking for a needle in a haystack trying to justify a large purchase that chances are you'll receive your money mostly back on when sold. I get the concern, but support will help make it right. Time to start supporting, otherwise the gloom will only increase around here. My belief is you need to be able to manage your own games and if something is faulty look to support they'll likely make it right.
