What owners wrote

Once again for the about 100th time our 2021 Ram 1500 EcoDiesel cuts off and when I means cuts off everything is off. No warning of any sort. Was going about 50mph and just completely shutdown on 880 Southbound in SF Bay Area. Truck has 52k miles is maintained and no codes no nothing. I had my children in the vehicle at the time of incident. We slowly pulled the shoulder with the help of rig driver slowing down to make sure no one hit us.
