If it seems to you that FCA recalls a lot of vehicles, you’re not mistaken. Out of 77 passenger-car recalls posted by the National Highway Traffic Safety Administration in the past three months, Chrysler brands have accounted for eleven. That’s over 14 percent, which is a fair bit more than the company’s domestic market share. (And don’t even get us started on Maserati.)

Now the Italian-American automaker has issued another, and it’s for about half a million vehicles. This time it’s Ram HD trucks that are being called in for a problem with their water pumps.

The problem, according to a statement issued by the automaker, is with a bearing in the water pump that could overheat and spark a fire in the engine compartment. Fortunately FCA says it is unaware of any such incidents occurring, let alone any injuries, and no longer uses the component in question.

The recall affects Ram 2500, 3500, 4500, and 5500 pickups and chassis cabs from the 2013 through 2017 model years – specifically those equipped with the 6.7-liter Cummins diesel six. FCA calculates there are nearly half a million of those out there: the vast majority (443,712 units) in the United States, with another 46,220 in Canada, and 4,485 abroad.

Those units will need to be brought in to their local dealers to have those water pumps inspected, and replaced where necessary. No timeline has been set at present, but in the meantime owners and operators are advised to pay attention to the warning light on the dashboard.
