On certain vehicles equipped with a 3.0 L diesel engine, a problem with the engine tone wheel could cause a loss of signal to crankshaft position sensor. If this happens, the engine could stall and you may not be able to restart it.
Safety Risk
A sudden loss of engine power could increase the risk of a crash.
Corrective Actions
FCA Canada will notify owners by mail and advise you to take your vehicle to a dealership to update the powertrain control module. This update will help maintain engine power if the crankshaft position signal is lost.
