What's wrong?
The reluctor wheel on the crankshaft is a timing wheel inside the 3.0L diesel engine on affected 2014-2018 Ram 1500 and Grand Cherokee vehicles. As the crankshaft turns, the wheel gives the crankshaft position sensor a signal the engine computer uses to time fuel injector pulses and camshaft timing. The engine needs that signal to keep combustion synchronized.
On these vehicles, the magnetic signal material can separate from the body of the tone wheel. Once that material delaminates, the crankshaft position sensor loses the clean signal the computer expects. The engine computer then loses synchronization for fuel injection and camshaft timing, which can result in an engine stall.
There is no warning sign before failure. The stall happens when the signal is lost, so owners should not wait for a dashboard light, noise, or drivability change to confirm the problem.

What happens at the repair
At the dealer, a Ram technician updates the powertrain control module software. The update lets the vehicle keep propulsion by reading the camshaft position signal if the crankshaft position signal is lost. The recall repair is free, with parts and labor covered. The manufacturer also offers reimbursement for owners who already paid to repair this problem before the field action. The owner letter asks customers to send the original receipt or other adequate proof of payment to the company so the expense can be confirmed.
