What's wrong?
The engine control module, or ECM, is the computer that manages the 6.7L Cummins Diesel engine in the 2016 Ram 2500, 3500, 4500, and 5500 trucks. It reads sensor signals and controls engine functions such as fuel delivery, timing, and electronic communication with the rest of the truck. The engine depends on that module staying powered and communicating correctly.
In affected trucks, the ECM can short circuit. A short circuit means electrical current travels where it should not, which can shut the module down instead of letting it keep the engine running. When the ECM drops out, the engine can stall because the computer is no longer controlling the diesel engine.
There is no warning sign before failure. The truck can be running normally, then stall when the ECM shorts, so an owner should not expect a warning light, sound, or change in engine feel first.

What should I do?
- Check your VIN to confirm your 2016 Ram 4500, 5500, 3500, or 2500 is included in this recall.
- Contact a franchised Ram dealer to schedule the free ECM replacement that fixes the no-warning engine stall.
- Bring the owner letter if you have it. If not, reference recall number 15V592 and Ram recall R52 when you call.
- Drive cautiously until the repair is complete, and pull over if the engine stalls.
What happens at the repair
At the dealer, a Ram technician replaces the Engine Control Module, the computer that manages engine operation, because the recalled module can short circuit and stall the engine. The replacement ECM and labor are free under the recall. If you've already paid for an ECM repair tied to this issue, Ram's reimbursement process asks for the original receipt or other proof of payment so the expense can be confirmed. Send that documentation through the instructions in the owner letter or ask the service desk for help.
