I'm back again with another problem this wonderful piece of crap that GM produced. I started noticing a small exhaust leak when I would start my truck but, it would go away as it warmed up. In Dallas this week we finally had a cold snap and my fantastic truck sounded like a tractor as I went down the road. So i took it to my Handy-dandy local dealer and they told me that it would cost $284 to replace the 15 dollar part. So I raised all sort of Hell and the manager who is new actually helped me for once. I guess since my truck is only a few hundred miles out of warranty. Anyways this is fixed for the time being and I am now wondering what the next issue will be.
