What's wrong, in plain English
Chrysler is recalling certain Ram 2500, 3500, and 5500 Cab Chassis trucks equipped with the Cummins diesel engine because an electrical short may occur in the intake heater grid relay, part of the truck's electrical system. This short could lead to a vehicle fire. Dealers will inspect the relay and replace it if needed, and in some cases will add insulating material to it after inspection.
What you should do
Contact FCA US customer service at 1-800-853-1403 to schedule an inspection with a dealer.
Until the repair is complete, do not park the vehicle inside a building or structure, or near other vehicles.
The repair is free of charge.
