Recall 22V642 affects 4,907 2022 Ram 2500, 3500, 4500, and 5500 trucks for an ECM short. Repair is free at any franchised Ram dealer.
Ram is recalling 4,907 2022 2500, 3500, 4500, and 5500 trucks because the engine control module can short-circuit after a misaligned capacitor causes an internal communication loss. That failure can cause a loss of drive power and increase crash risk, and Ram dealers will replace the control module free of charge.

What's wrong?
The engine control module on these 2022 Ram 2500, 3500, 4500, and 5500 trucks is the computer that manages key engine functions. On Cummins 6.7L turbo diesel models, it reads sensor inputs and sends commands that keep the engine running as designed. The module depends on small internal electrical parts staying aligned and insulated.
In the recalled trucks, a capacitor inside the engine control module was built out of position. That misalignment can create a short to ground inside the module. When that happens, the module loses internal communication, so the engine computer no longer passes signals the way it should. Ram's repair uses an engine control module without the misaligned capacitor.
There is no warning sign before failure. The problem is inside the module, so an owner is not given a reliable sound, smell, light, or driving feel that proves the failure is about to happen.
