Ram 1500 diesel sensor ring may cause engine stall

NHTSA campaign 20V475000 · Reported 2020-08-13 · Chrysler (FCA US LLC)

high How serious is it? About this label

Serious, since an engine that stalls while you are driving can lead to a crash; the notice does not tell owners to stop driving, so you can keep using the truck, but get the free update soon.

What's wrong, in plain English

These trucks have a 3.0-liter diesel engine. A toothed ring on the crankshaft, which the engine uses to keep track of its own timing, can come apart in layers. If that happens, the engine loses the signal it needs to time the fuel injectors, and it can stall. The fix is a software update: the engine computer is reprogrammed to use a second timing signal from the camshaft so the engine keeps running if the first signal is lost.

What you should do

2. Contact your Ram dealer, or FCA US customer service at 1-800-853-2002, to book the engine computer software update.
3. Have the update installed — it is free, and it usually takes only a short shop visit.
