Anyone have an extended service plan had the plugs changed by the dealer and had a plug or plugs break and have it covered under warranty?

I have a Ford ESP and am thinking about having the dealer change out the plugs at 50,000. They gave me a rate of 200 something to have it done if everything goes right, I was hoping the ESP would cover anything extra if the plugs break.

Anyone have any experience on this?

 

I don't recall anyone having succeeded. I think it is considered normal maintenance.

 

I inquired about this with my dealer, they said that with my Ford ESP I was covered!......
