306,000 Ram HD Trucks Recalled for Fire Risk, Owners Should Park Outside

Owners are told not to park the vehicles inside garages or buildings until the problem is fixed.

Stellantis said today that it will recall 306,165 of its Ram HD pickups and chassis-cab trucks from the 2021 through 2023 model years. The issue is an intake heater grid relay on trucks equipped with the 6.7-liter Cummins diesel engine; the affected trucks use an older design of heater grid relay that is no longer being installed. The automaker had previously recalled Ram HD trucks for the same problem in late 2021.

Stellantis said the relays could overheat, which opens the possibility of fire. The company said there were six fires reported that could have been related to the issue. Five of these happened while the vehicles' engines were running, while the other was with the engine off. The automaker said the risk is "minimal" but still advises owners or users of the trucks not to park them indoors.

The company will start notifying customers in March. Until then, owners can check the National Highway Traffic Safety Administration (NHTSA) recalls website to see if their truck is involved in the recall.
