will gmc pay for a new motora

What is your question?

I have a 2015 gmc sierra 2500hd there's around 150,000 miles I take very good care of it. I was on vacation in Vegas i was leaving the bank and going to the hotel when I stopped at a red light i noticed it was idling ruff then I seen a ton of grayish smoke coming out so I take it to gmc dealer there and all they tell me is that I need a new motor so I take it to a diesel mechanic and he tells me that a glow plug broke off into number 7 cylinder a month later I look into it More and find out there is a recall on my make and model of truck for a glow plug module I look up to find out that a messed up glow plug module can cause my glow plug to break off with all this being said will gmc pay for my motor
