Mitsubishi Repair: Mitsubishi Camshaft, new car warranty, oem parts


Question
Hi, I have a problem. I have a 2004 mitsubishi lancer, bought it brand new, still have my warranty that is about to expire in early april this year.

On the way to work my car stopped. Roadside service believed it to be a camshaft problem/ timing belt. I have done all required services for the car and had replaced my timing belt in october of last year. Had it towed back to the mechanics who placed timing belt in, they showed me that it was still intact and it wasn't the belt that caused my camshaft to break.

I then had it towed back to the dealership where i intially bought the car from. They FIRST claim it is the timing belt that caused it to break. They NOW claim it is a non genuine timing belt that was put in. And that voids my new car warranty. Im confused? I guess my question is how is it possible for the belt to jump the teeth, snap my crankshaft then place itself back on in perfect position again? Now the belt is is perfect condition still, no marks etc.

Shirley,
The camshaft itself is an extremely strong piece of metal.  It's simple a thick metal rod with paddles on it that pushes the valves down to let clean air in and exhaust gas out.  For that to truly break, I would assume it was a poorly manufactured part; which your drive-train warranty should still cover.  It sounds like the dealership is trying to find a loophole in the warranty so they do not have to honor it.  

Because of the excessive labor and parts cost that the dealership should have to absorb in honoring the warranty, I can see why they are pushing back and putting the blame on the belt you had installed back in October.  You may want to read over your warranty very carefully and see if there is anything mentioned that may say something like "only the dealership may perform service on the vehicle and can only use genuine Mitsubishi OEM parts."  You may even want to have a lawyer look into it if you know for sure your warranty is still valid.

And to answer your question, it is impossible for a timing belt to jump teeth, break the camshaft, and re-seat itself properly back on the cam sprocket :).  
Good luck!
