Check engine light or misfire

The Office of Defects Investigation (ODI) has received 80 consumer complaints alleging an engine stall and loss of motive power on model year (MY) 2022 RAM 1500 pickup trucks and 2022 Jeep Wagoneer SUV vehicles. The particular engines in the subject vehicles are equipped with the Fiat Chrysler Automotive Group LLC (FCA) 5.7L Hemi eTorque system. The eTorque system is a mild hybrid system that lets the vehicle partially power itself. It accomplishes this by converting the captured energy from the braking system into electricity for the battery pack, which is then used to power a variety of electrical components. ETorque engines replace the alternator with a 48-volt battery-powered belt drive and a motor generator. The motor generator provides extra torque to the crankshaft during gear changes. Simultaneously, the motor generator uses the 48-volt battery pack to increase torque. Many of the complaints state that the vehicle's engine would shut off, often while travelling at slow speed, the vehicle would shift into park and apply the emergency brake. The vehicles were sometimes able to be restarted. In addition, complaints state that the malfunction warning light with the battery fault symbol appeared on the dash. Many complaints state that a low voltage condition fault is present, sometimes not being able to restart the vehicle. On April 13, 2023, FCA announced recall 23V-265 describing a defect in certain 2021 Ram 1500 vehicles equipped with 5.7L eTorque engines. The recal
