What's wrong, in plain English
On these vehicles, the fuel supply lines may not have been properly attached, and they may not be fully seated where they connect. Because the lines are not secured the way they should be, they can gradually work themselves loose or come apart entirely. When a fuel line separates like this, gasoline is able to leak out of the fuel system. A leak of this kind raises the chance that a fire could start.
What you should do
Where do I find my VIN, and what do I tell the dealer?
