GMC Yukon Broken Exhaust Manifold Bolt

in GMC
I have an 07 Yukon SLT with the 5.3 engine, bought used last fall with 55k miles. I was cleaning the engine area and noticed an exhaust bold sitting crooked on top of the spark plug boot. I thought it was cross threaded, but realized it was broken when I touched it. There's never been a wrench on the engine with this Yukon, according to the dealership where I purchased it. I also purchased an extended warranty.
When I took it to the local GM dealer they told me that the extended warranty did not cover broken bolts. Had I ignored it until the manifold was leaking, they would have covered it.
Why would the GM 5 yr, 100,000 mile drive train warranty not cover this item, in lieu of my non-performing separate warranty? They quoted me a price of $290.00 to repair.
Has anyone else had this kind of problem with exhaust bolts breaking? The service writer did not seem surprised and even guessed that it was the front bolt before even looking.
