Brand new Ram 2500 Diesel caught fire after about 1100 miles. Best I can tell it started around the alternator. Made a low "whirring" or "humming" noise during a few short drives just prior to the event that had not happened before. I was just parking when I noticed smoke coming from under the hood and opened it up to find a small fire involving the alternator and extinguished it with a fire extinguisher. The fire department came out and ensured it was extinguished and then a fire investigator came out and conducted an investigation. Took three days to get the dealership to accept the truck being towed back so it can be investigated by manufacturer.

My truck was started in the morning and as it sat idle in the driveway I started attaching my trailer. By the time I got the trailer attached(20 seconds) there was smoke pouring out from under the hood. I immediately turned off the truck popped the hood and it was engulfed in flames. I was able to put out the fire with the garden hose. No check engine lights, no warning lights on dash, and I had just got it back from the dealership 2 days earlier and it passed a safety inspection before I picked it up. Im not sure what component failed but whatever did caused a fire
