NHTSA Complaint #11670247 — 2021 RAM 1500

The MGU of the 2021 Ram Laramie (e-torque) is not functioning properly and hampers the safety of the vehicle. The MGU, which controls the alternator, will not charge the battery beyond 13.0/13.2 volts during driving. As a result, when sitting for several days, the battery will not have sufficient voltage to start the vehicle since it is not charged fully during driving. Additionally, the MGU is now making a strange bearing noise so we will see if a failure is imminent. Considering this MGU controls the starting of the vehicle during stop/start, and the battery is not charging sufficiently to ensure the owner is not stranded, I consider this a significant safety issue (especially when I live in a place with winter of 8 months). I have not seen any warning lamps, but the charging indicator/screen shows 13.0 as below normal.
