Can anyone tell me if the VERY COMMON problem of broken exhaust manifold BOLTS are covered under the 5 year/60,000 mile warranty? When I asked last spring at my local dealer while I was there for an oil change it was just "Not part of the power train" but now I'm starting to really wonder. I turned 5 years in October but am at 58,000 miles. If the dealer steered me wrong last spring I'm going to be a little bit unhappy.
