Rings and cylinder walls wear out. It is inherent in the design. You have one piece of metal that sprung to press against another piece of metal so hard that it makes an air tight seal. There is a thin layer of oil between the two pieces of metal and oil today is better than oil fifty years ago. Still, the coefficient of friction is not zero. Anytime there is friction between two objects, one or both exhibits some wear after a certain period of time. If you can accept that things like brake pads and clutches are wear items, it is not a leap to accept that rings and cylinders also wear out. It is impossible to build piston rings and cylinders that do not wear. The Wankel Rotary engine is a good example of two parts wearing. The seals between the rotors and combustion chamber are notorious for leaks, despite the many years the engine has been in production. Their wear rate is much much higher than a piston engine.
If the warranty was that extensive, I would think their ads would be proclaiming "This is the last vehicle you will ever have to buy!" Wouldn't that be a hell of a selling point and something to capitalize on?
My Jeep only came with 3 year / 36,000 mile warranty. I'm not worried about it. If I was, I probably would not be able to fun in my Jeep.
