    Fuel system, gasoline: storage: tank assembly

    Honda is recalling certain model year 2012 pilot and acura mdx vehicles. The vent shut float (vsf) valve case in the fuel tank assembly does not meet the design specifications.

    Risk: As a result, fuel may leak from the tank, increasing the risk of fire.

    Fix: Honda will notify owners and dealers will inspect the vsf assembly date and, if necessary, replace the fuel tank assembly, free of charge.

A recall only helps if the repair was done. Enter the vehicle's 17-character VIN on NHTSA's official recall lookup before you buy.
