NHTSA Complaint #11719736 — 2020 RAM 1500

My 2020 Ram 1500 Laramie was parked in my garage. I started it to let it warm up before driving. The garage started filling with smoke and the smell of fire. I backed the truck out of the garage and noticed flames on my backup camera. The 7 way plug was on fire. I quickly shut the truck off as soon as I got it out of the garage. I put water on the fire to get it out before it took over the back end of the truck. I had drove the truck the day before and filled it up with gas so my life and my son's life was as risk knowing there is a electrical issue. It also was parked in our garage when it started smoking and it could of burnt the whole garage and house down if I didn't get it out of there as fast as I did and noticed it burning. I had contacted 3 dealer ships and they all said sorry we can't help you. I decided to contact Ram directly to file a claim. Ram told me specifically not to take it to any dealer and they would look into it. 3 weeks later they sent out an investigator to my house. They took pictures of the truck and the damage. They plugged in a code reader and it didn't throw any codes. I asked the guy for the report and he said he couldn't give me one. I have since heard back from Stellantis and their email said things like this happen and they have declined any further assistance associated with this fire. They than said to contact the insurance. A fire is a safety issue and there is major concerns of safety. I don't feel safe when they said it was safe to drive after they did the investigation. I took it to a dealer ship to have it repaired and it started to smoke twice driving it to the dealership.
