Leaks are not that uncommon as people think. Go to any car brand forum and you will see complaints of engine oil or other fluid leaks and even water leaks. It happens. I have 18k on mine and no oil leaks at all and most others don't either. Their are some that are leaking from the gasket but very few and are being fixed for free. It happens. Remember these engines are still built by humans and none of us are perfect everyday.
