Consumer Description

Started hearing bearing noise from the eTorque MGU (motor generator Unit) at around 40,000 miles on odometer. Took the vehicle to dealer for problem determination and they confirmed it was a problem with the MGU. I was told a total failure can cause the main electrical fuse to fail without warning leaving the vehicle completely without power in traffic. There is also the possibility of the bearings seizing and the entire pulley shearing off while in operation. Through two different online owner forums, I have verified that this appears to be an increasingly common problem with 2019-2024 models. RAM appears to be aware of this problem as they issued a Technical Service Bulletin on 1/1/2022 (S2208000009) which talks about the bearing noise and underlying problem.
