Ram Heavy Duty Diesel Trucks Engine Fire Risk
critical How serious is it? About this label
Serious — a fire can start in the engine bay even with the truck shut off, so park outside away from structures until the relay is replaced; the notice does not tell owners to stop driving.
⚠ Park outside, away from buildings — fire risk. See all such recalls.
What's wrong, in plain English
These diesel trucks use an electric heater to help the engine start in cold weather. The relay — the switch that turns that heater on — can short out electrically, and it can do so whether the ignition is on or off. A short there can start a fire in the engine compartment. A dealer will replace the relay free of charge. The repair is being rolled out in stages, starting with 2023 models, then 2022, then 2021.
What you should do
2. Park outside, away from buildings and other vehicles, until the relay is replaced.
3. Call your Ram dealer or FCA US at 1-800-853-1403 (recall 13A) to schedule the free relay replacement.
