NHTSA recall 07V278000

What's wrong: On certain trucks built with 26 gallon fuel tanks, the fuel tank may have a depression at the seam between the top and bottom halves of the tank (not visible from outside the fuel tank). If a depression is large enough, fuel may permeate the fuel tank wall resulting in a fuel odor, or a "service engine soon" indicator light.

Why it matters: If left uncorrected, a fuel leak could eventually develop. A fuel leak in the presence of an ignition source could result in a fire.

The fix: Dealers will replace the fuel tank free of charge. The recall began on June 25, 2007.
