Hey guys. I just bought a 2015 2500 Ltz truck last week. Truck has 300 miles on it at this point. Story is, yesterday I was walking by the truck and noticed the lights flash. I looked over and then the lights came on and the starter started turning but it wouldn't crank. It did this for 3-5 seconds and then stopped. One key was on the console in the truck and the other was in my safe. I say this because I originally thought that someone was screwing with me. The doors were also unlocked, which tells me that It wasn't caused by a key fob. Anyone ever heard of anything like this?
