Fiat Chrysler is recalling almost a half a million Ram pickups with 6.7-liter engines.
According to the company, a water pump issue could cause the trucks to catch fire.
The recall affects the 2013-2017 Ram 2500 and 3500 pickups, and the 3500, 4500 and 5500 chassis cabs.
A company spokesman says the problem could cause the trucks to overheat, exposing drivers to everything from a burning odor to a fire.
