2025 RAM 2500 Engine Problems

Subject: Safety Concern – Vehicle Shuts Down While Driving / Request for Replacement Despite multiple warranty repair attempts, my 2025 Ram 2500 continues to experience unresolved electrical failures. In addition to the previously documented issues, the vehicle shuts down while driving, forcing me to immediately pull over, place the vehicle in park, and restart the engine in order to continue driving. This condition has occurred unexpectedly and without warning. Losing power while the vehicle is in motion presents a serious safety risk, especially during highway or interstate driving. Given that I rely on this truck for work and frequently travel long distances between New Jersey and Texas, this behavior makes the vehicle unsafe and unreliable for its intended use. The truck has already undergone repeated diagnostics, module replacements, software updates, wiring repairs, and battery replacement at authorized Ram dealerships. Despite these efforts, the issue persists. At this point, I have...

Check engine light consistently comes on with codes p0263, p0272, p0266 for contribution balance codes for cylinders 1, 2, 4 & 5. Truck runs rough. Dealership says it’s a 5-8 week process to test and get injectors into replace if that’s the issue. 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...

On Sunday, 9/14/25 driving on a 70 MPH interstate highway, pulling a trailer behind the Newly-purchased 2025 truck (only 700 miles on it), the road narrowed down to one lane because of a traffic obstruction and cones. As I slowed down to about 35 mph and then went to speed up again as the traffic eased, the vehicle provided a ping notification sound and the Electronic Vehicular Instrument Cluster (EVIC) display stated something to the effect of "Shift into 'P' to start vehicle". I realized that the vehicle was not responsive as expected, indicating power steering had failed, likely because the engine was off. I'm uncertain whether the steering wheel was locked, which is likely, because at that speed, only a very slight turn of the wheel was needed to move into the closed lane on the straight road. I continued to coast to get the vehicle and trailer over...

When letting off the gas and coasting to turn on a road around 10 mph, vehicle motor shut off and lost power steering control. Vehicle alerted to place vehicle in park, press break and push start button. Vehicle started back with no issues. Reported to dealer, dealer picked up and stated they could not find any issues and returned to me. Following day while going to work vehicle again shut off when pulling up to a gate entry and then again approaching my return to home at stop sign. All three times vehicle was under 15 mph and approaching turn/stop. New Truck, only 30 miles on it when first incident occurred and only 160 miles now. Dealer still not able to duplicate or locate the problem. System is showing no codes.
