What 57 owners told NHTSA about the 2025 Ram Ram 2500 Regular Cab

I parked in a lot for about 30 minutes while taking a short hike. When I returned and started the truck the dash was black, no gauges, no PRND indication, nothing and the warning lights in the mirrors stayed illuminated continuously. We were in a National monument and decided to try and get back to the visitor center for someplace safe. When I placed the vehicle in what should have been reverse the vehicle rolled back but only because it was on a slope. When I shifted to where drive should be nothing happened. I tried several times as we were now in the traffic lane on a curve. I went completely back to park then cycled to drive and it worked. On the drive to the visitor center I noticed that the blinkers did not work either. Also, what I thought were manual gauges like the speedometer and fuel gauge did not work. When we got to the visitor center the vehicle would not shift into reverse from drive. I had to go back to park and then to reverse. I was able to get the vehicle working by disconnecting the negative battery cable for about 5 minutes. This just happened today and we are 1500 miles from home so the vehicle has not been inspected. If another car would have come around the corner while we were disabled they would have hit us as it is a one way loop so only one traffic lane that we were in.

Multiple sources have stated it can be a software update issue and some states still waiting after weeks for fix to be made and paying for a rental car out pocket to have reliable transportation for work and taking care of kids.

While driving in 4x4 on a snow covered road, the truck simultaneously got a check engine light as well as several other error messages to include service required to the emergency braking and the trailer brake controller. At the same time, the full exhaust brake engaged without any driver input and caused a sudden slowing of the truck's tires on a slippery surface. The owners manual specifically warns "Do not use the exhaust brake feature when driving in icy or slippery conditions as the increased engine braking can cause the rear wheels to slide and the vehicle to swing around with the possible loss of vehicle control, which may cause a collision possibly resulting in personal injury or death." Fortunately I had a lot of weight in the truck when this happened and I was able to control it, but a malfunction that turns on the full exhaust brake, especially while 4x4 is engaged, is dangerous enough that there is a warning in the manual. This happened twice. I had a solid check engine light on, and the following day while waiting for a service appointment, a slew of new warnings were flashing across the screen, locking the transmission in 6th gear, advising the 4x4 was no longer available, and may others. I attempted to shift from drive to reverse, the gear shifter locked itself in park. I shut the truck off to try restarting it and moving it, but there was no power getting to the truck to use the sos button to call for help in a poor cell reception area, no lighting worked while obstructing half of a travel lane on the roadway. The truck had good voltage prior to this. The truck was towed to the dealer with 5100 miles on it.
