NHTSA Complaint #11694911 — 2023 RAM 1500

I have taken my truck in to the dealership twice already for the same issue and they are telling me they cannot find the issue. My truck would not start, so I replaced the battery. Noticed that the voltage would drop after driving it about 20 miles or so. Normal range is 13.5V. Starting the truck, it starts out at 13.5V but after about 20 miles or so, the voltage would drop to 12.5V. Dealership could not find out why. Engine light is not on but the voltage drops every single time I drive. I bought it with 11 miles on it in June of 2023 and didn't have this issue until September of 2025. The truck only had about 37,400 miles on it when it started messing up. I am scared/worried that the truck will just stop while driving. I have read many forums and stories about many others are having this issue too. The Motor Generator Unit (MGU) malfunctioning. There are recalls for 2019-2022 MGU but not for 2023 or later.
