Following an investigation by the National Highway Traffic Safety Administration, Chrysler will extend fuel-tank warranties on 153,817 V-8 cars from the 2006 model year. The extension applies 5.7- and 6.1-liter versions of the Chrysler 300 and its Dodge Charger sibling, plus the now-defunct Dodge Magnum wagon. Dodge, like Ram and Jeep, is one of Chrysler's brands. After receiving hundreds of reports that after refueling the V-8s in all three cars may stall at low speeds or when stopped, NHTSA opened the investigation.

The agency found that when you put in higher-ethanol gas, a malfunctioning shut-off float in the cars' 19-gallon fuel tanks could swell into a stuck-open position and allow fuel to enter what's called a "purge line," NHTSA said via the Detroit News. That, in turn, could make the cars stall shortly after you refuel. You can restart the car after it stalls, and NHTSA said the problem never represented a serious safety threat. Chrysler addressed the conditions with a new fuel shut-off valve that's more resistant to changing shape, spokesman Eric Mayne told us. NHTSA deemed the solution adequate, the Detroit News said. The agency closed the investigation today, and Chrysler said it will extend fuel-tank warranties on the vehicles involved to a lifetime provision.
