NHTSA recall 11V355000

What's wrong: The fuel tanks may not have consistent welds between the fuel tank and fuel filler neck spud which can affect the strength of the joint. Some fuel tank spud welds may not provide the expected strength in the event of a severe rear impact to the vehicle. An improper weld can result in a crack in the joint which could illuminate the emissions malfunction indicator light, cause a fuel odor, or allow fuel to leak out.

Why it matters: Fuel leakage, in the presence of an ignition source, could result in a fire.

The fix: Dealers will replace the fuel tank free of charge. The safety recall began on August 16, 2011.
