rstrick, I'll bet most here would think that if the line was cut by an OEM component that's part of the original truck, it should probably be something covered by warranty. I'd think it would indicate an improperly placed clamp or whatever cut the line, or at least an improperly located vent line where it wasn't safe for the line. Now, if a rat/mounse chewed the line, then that could be argued against a warranty. I've seen many wires chewed by rodents on motorcycles, vehicles, and even house components...phone lines, TV cables, etc. If you're going to get Dodge to fix it, I would obtain the allegedly "chewed" piece of line and have it checked by a pest control expert to possibly support your side of the issue. I think it's easy to tell a rodent chew vs. a cut line. Unless it's a very tiny wire, you can always see the little bugger's multiple bite marks on the component that was chewed.
All that said, the $1500 price sounds insane. Why can't the line just be spliced with a very professional method or replace all or the bulk of the line with a quality material to insure a good seal so that the code isn't thrown. It sounds like their pricing reflects some kind of wholesale replacement of the charcoal canister and every stinking line in the evap and vent system. Maybe they have some kind of legal limitation as to how they repair an emissions component. In this era of totally assinine fed intervention into every aspect of life, if could be the case. If so, find a good mechanic who can fix the problem instead of throwing out the baby with the bathwater.
And understand that I'm basing most of my response here on the fact that it's a vent/evap line or something like it that's relatively simple. If it's a hole in the gas tank or something major affecting the evap system, then cost is going to rise accordingly.
Still, barring absolute proof that a rodent chewed a hole in anything, it sounds more like a warranty issue of something being cut or rubbed through by chaffing...especially on an '11 model.
