Damn. Make sure you try to leverage the 3rd party warranty. It'd be pretty stupid to buy the warranty, not even get to your first oil change and have a problem, then be denied the claim. They can't say you didn't maintain it, it hasn't been long enough! Get that KM fixed up on the invoice! Or at least if Mitsu won't do that for you, hammer that 3rd party call centre. They can be a bitch to deal with but if you push enough you should get somewhere.
