I have seen a few posts about tank issues in general on multiple sitesI just joined this forum hoping to see if anyone has had my problem yet, but I think not. We just purchased a 2008 G8 GT a month ago. It has performed great but the check engine light came on. Long story, short, I have to have a new gas tank because there is a crack in the seam which is allowing air to escape and possibly fuel. The catch is my dealer is having a problem locating a part. So even though we like the car, I wanted to let you guys know about my problem. I hope it is not something that becomes a "recall" or something. Thanks for listening.
