Gordon,

Well put. Your posts in this thread have been very good.

No matter who makes your turbine, or what they write in their warranty cards, if they're sold in the United States, then their sale is under the jurisdiction of the U.S. Uniform Trade Act. There is a section in that law that states simply that if, due to defect, a product cannot be used for the purpose for which it was sold, then the purchaser is entitled to a return/refund. That supercedes any shop or manufacturer's policy or statement on their receipt or warrany card, even in the case of electric or electronic items or components. Nobody should have to pay for an upgrade to fix a problem that's in the design, if the problem means you can't do with the engine what you bought it for. Maybe somebody will give the seller the 'option' to fix it, free, or give back the money the buyer spent on it.

That's not to say that the user can't screw up an engine, but when manufacturer admits that there is a flaw, shouldn't that be the end of the 'cost to fix' discussion?
