Fiat Chrysler Automobiles (FCA) USA will be contacting the owners of certain 2022 Ram trucks because their vehicles may have a manufacturing defect within the Engine Control Module (ECM) that could affect vehicle safety. This defect affects vehicles equipped with Cummins 6.7L turbo diesel engines and could result in an unexpected engine stall.

The RAM trucks affected by this defect include:

The FCA Technical Safety and Regulatory Compliance (TSRC) organization became aware of the problem in August 2022 when they were contacted by the RAM truck assembly plant regarding suspect ECMs manufactured with a defective component. According to the NHTSA safety report, some ECMs may have been manufactured with a misaligned capacitor that could short-circuit and create an internal loss of communication. This internal loss of communication could result in a loss of motive power and an increased chance of an accident.

The suspect period for these defective ECMS began on May 31, 2022, and ended on August 23, 2022, when the ECMs were quarantined. This time period was determined using supplier traceability and vehicle production records. Similar vehicles not included in the recall did not receive suspect ECMs or were repaired prior to release from the assembly plant control.

Owners who receive notices will be asked to return to their dealers to have ECMs in their trucks replaced. FCA US, LLC’s number for this recall is Z87 and the NHTSA campaign number is 22V-642.
