“I started my 2018 Ram 2500 in the early morning and a message popped up in my message center ( service 4x4 system) . Usually it would not be a big deal because you should service your vehicle to keep up with maintenance , but I just bought the truck 10 months ago and it has 5000 miles on it. Have an appointment with dealer to find out the problem, 4x4 will not engage in the mean time.”

“I was pulling my 5th wheel trailer up a steep hill, and my engine fan sucked in my fan shroud cut it into large chunks, they then flew into my radiator and punctured it resulting in loss of all engine coolant. Apparently this has been happening for quite some time with 4th gen Ram trucks after searching on multiple internet forums. This in my opinion should be a recall. It left my 2 kids, wife, and two dogs stranded on the side of the road.”

At time of purchase it had 555 miles on it, and we'd only driven it 3 time prior to this. We were driving below the speed limit. The truck starting loosing power, we saw a little smoke in the rear view mirror. As we slowed the smoke increased. Upon lifting the hood, transmission fluid was squatting out across the engine poring on the ground, flames were moving along the back of the fire wall. We put the fire out ourselves prior to the fire department arriving. …”
