I heard a clicking noise from under the hood and after pulling off the cover plate for the engine exhaust manifold I saw the manifold was cracked. At idle speed fumes get inside vehicle. Repair has not been made so old part is available. Upon research on the internet there are numerous other complaints of this problem. I sent an E-mail to GM and someone called and said they need more people to report it to get something done. I believe it is a safety issue because of the fumes and possible fire hazard.

Started to hear loud rattle coming from rear of vehicle, thought maybe a heat shield around muffler went bad. Took it into the shop and they stated "not sure what happened, though you have something that has come loose in the resonator". around $100 to get the resonator removed, have not quoted a new one from the dealer yet. I would imagine the replacement part will fail just as the original part has done.
