NHTSA Complaint #11538838 — 2023 RAM 1500

Incident #1: July 29 2023 Truck was purchased at 16 miles on the odometer and approximately at 160 miles the check engine light came on. The truck was coming to a stop when in sputtered, and the check engine light came on a few seconds after. The truck was drivable and was driven a few miles to my home. The truck was driven a few days later and the electrons on the truck such as the radio started to turn off, followed by a battery warning. I went to pull the truck over immediately as the engine was sputtering. I attempted a jump start of the truck and it ran for a few minutes then shut off. The truck battery was charged and put on a tow truck and sent to the dealership. They replaced the MGU "Motor Generator Unit" after which the issue appeared to have been resolved. The battery charge read between 13.8 - 14.2v and right in the middle of the battery charge indicator. Incident #2 August 15th 2023 The truck was parked at the Reno Airport, and when my flight was canceled, I decided to instead drive to San Francisco. The truck was parked in the sun for about 4 hours before it was driven again. I started driving and a few minutes later, was coming to a red light, started to apply the brakes, there was the same feeling of engine stalling when coming to a stop. The engine didn't stall, and no Check Engine light illuminated. I started the 25 mile uphill drive from Reno to Truckee, and noticed that the battery charge was slowly dropping down to 13v, then 12.8v, then to 12.7v when I got to Truckee. I pulled the truck over, restarted it and the voltage slowly climbed up to 13v and I resumed the drive. I started the climb to the Donner summit over i-80, and noticed the battery charge indicator dropping slowly. Approximately 65 miles later then charge was reading 12.4v and the low battery indicator light came on. I pulled the truck over to avoid it from stalling out like it did during the first incident.
