The car started making a weird sound, thought it was transmission because it only happened when i accelerated. Took it to the dealership abd they wanted to charge me $1000 plus labor. I said no,this is a deffect and it should be covefed by the warranty, the said it wasnt. So i took it to a exhaust shop and they welded it but it cracked again and after a while, it actually tore a little hole into the muffler. So i let it be, maybe make the repair when i had the money to spare. But money being the issue, i went to a muffler shop and had it re soldered, it worked for a while, but now its back. It sucks thay gm put out the recall for specific vehicles knowing that it is a very general thing. Plase help me.
