“In the last 2 months my truck has lost all electric power while making a slow right turn. Voltage drops and I lose power steering. Dealership put a new battery despite there being an active recall for this exact issue. However, my VIN number is not included in the recall. I was able to video it happening. It happens when the vehicle is in motion”
