I know that this is never going to happen but IMHO lying and misrepresenting that repairs are required when they are not, is fraud, and should be treated the same as someone stealing your wallet.
I had my fall oil / filter change at local Kia dealer. If you own a Kia you probably know all of Canada is designated as being subject to the "severe service" maintenance schedule, not the normal or routine one. This is a license to abuse customers and sell them services they don't need. If all of Canada is "severe" then there should be no such thing as a normal schedule in your owner's manual.
So this time my differential / transfer case was checked for proper oil level as recommended at 75k km. Normal service schedule says never change oil, severe schedule says change at 125k km. Dealer recommended changing it at 75k km for $300. Declined. Lots of similar examples of service recommended in advance of the contrived severe service schedule, but declined.
