FCA is recalling roughly 58,000 vehicles in the United States to update powertrain software that will help prevent engine stall in diesel-equipped Ram pickups and Jeep Grand Cherokee SUVs.
An FCA investigation discovered the tone wheel in a small percentage of engines may, over time, lose magnetic material. Should this occur, it may disrupt signal transmission to a sensor that monitors crankshaft position – a condition that may contribute to engine stall.
The recall is limited to certain model-year 2014-2019 Ram 1500 Classic pickup trucks and Jeep Grand Cherokee SUVs equipped with 3.0-liter diesel engines.
FCA is unaware of any related injuries or accidents. However, the company urges customers to follow the instructions on their recall notices; mailing will begin no later than Oct. 1. Service will be provided free of charge.
Customers with additional questions or concerns may contact their dealers or call (800) 853-1403.
Like-model vehicles equipped with gasoline engines are not subject to this recall. And vehicles equipped with FCA’s newer, third-generation 3.0-liter EcoDiesel V-6 are similarly unaffected.
Additional vehicles will be subject to recall in Canada (est. 22,079) and certain markets outside North America (est. 51,879), a population that also includes model-year 2014-2019 Chrysler 300 full-size sedans equipped with 3.0-liter diesel engines.
