The contact owns a 2023 Ram 1500. The contact stated that while driving on several occasions at various speeds, the seat belt, ABS, check engine, and other unknown warning lights illuminated. The contact stated that the messages “Service Transmission – Continue in D – Do Not Shift or Turn off Engine until You Reach a Desired Location”, "Service Power Steering", "Service Parking Brake", "Park Sense Temporary Unavailable", "Service Transmission – Continue in D”, and “Do Not Turn off Engine”, “No Buss” were displayed. Additionally, the windshield wipers activated inadvertently. The contact stated that on one occasion, while in the middle of traffic, the vehicle was pulled over to the side of the road and the contact attempted to turn off the vehicle by depressing the ON/OFF button, but the vehicle failed to turn off. After several attempts, the contact was able to turn off the vehicle. The contact turned off and restarted the vehicle several times to reboot the vehicle. When the vehicle was restarted, the vehicle failed to accelerate. The vehicle was towed to a dealer where it was diagnosed that there was an unknown issue with the wiring on the passenger’s side of the vehicle. The vehicle was repaired, but the failure reoccurred 1 year and 7 months later. The vehicle was taken to another dealer where it was diagnosed and determined that the CAN-C network was offline, the OCM was the module taking the bus down, circuit D13 was at 0.37 volts instead of 2.7 volts, and D14 had 0 volts, indicating a ground short. A connector was found in the wiring diagram closer to the OCM that should only have the OCM in it. D14 was rubbed through on the seat frame where it ran down from XY420A. While the technician was removing the wiring harness, the short to ground was no longer present. The rubbed section of the wire was cut out, and a new wire was installed, but the failure reoccurred within 24 hours. The vehicle was taken to the same dealer where it was diagnosed and determined that wiring needed to be resecured. The vehicle was

First incident, vehicle completely lost power and turned off while driving down highway, fortunately I was able to coast in to shoulder and request a tow. Second event the vehicle flashed all warning lights while traveling down interstate and had a quick shudder. This was similar to first incident. However, lights eventually cleared themselves and power wasn’t lost. Third incident vehicle warning lights flashed on and lost power. Eventually restarted and drove to dealership. Mechanic visually witnessed vehicle lose power again while in inspection bay. Engine control module was replaced during visit. Two weeks later, vehicle failed to start again with same symptoms of all the warning lights and check engine lights being on. Vehicle was able to start next day and was driven straight to dealership where it currently sits. These repeated and spontaneous engine failures, including when driving at highway speeds, are an extreme risk to my life and the life of others and are unacceptable for a vehicle with 45,000 miles.

The vehicle was taken to the residence and then to a dealer, where the failure could not be duplicated. During the second occasion, while driving up a bridge, the vehicle lost automotive power and the vehicle decelerated to 28 MPH. The vehicle then coasted down the bridge, and it was pulled over to the side of the road, turned off, and restarted. The check engine warning light became illuminated. The vehicle was parked for several hours during a class, the vehicle was restarted and reset independently, and the warning light was no longer illuminated.

I have taken my truck in to the dealership twice already for the same issue and they are telling me they cannot find the issue. My truck would not start, so I replaced the battery. Noticed that the voltage would drop after driving it about 20 miles or so. Normal range is 13.5V. Starting the truck, it starts out at 13.5V but after about 20 miles or so, the voltage would drop to 12.5V. Dealership could not find out why. Engine light is not on but the voltage drops every single time I drive. I bought it with 11 miles on it in June of 2023 and didn't have this issue until September of 2025. The truck only had about 37,400 miles on it when it started messing up. I am scared/worried that the truck will just stop while driving. I have read many forums and stories about many others are having this issue too. The Motor Generator Unit (MGU) malfunctioning. There are recalls for 2019-2022 MGU but not for 2023 or later.

On 3 separate occasions the truck has completely broken down while traveling 60-84mph. Each time, while in motion, the check engine and battery lights come on on the gauge cluster. Voltage starts rapidly draining from the battery indicator before systems start being shut down. Fiirst is entertainment, then climate, the ABS, then steering, and then all power and engine loss. I almost lost control the first time while trying to make it safely over to the soft shoulder. Each of the three times this had happened, the truck was completely dead in the side of the road and was towed to a dealership three times. The truck was towed to 2 different dealerships. The first two times to Imperial Dodge where they charged the battery the first time and did a software update the second time. Most recently the truck had been at DCH Temecula, for two weeks, where nothing has been done due to them not being able to recreate this issue. They recommended that I take video, while driving, as the issue happens live. This is a major safety issue in general but unacceptable that the manufacturer and dealerships only solution is for me to put myself and my family in jeopardy, and break California law, to diagnosis this massive unsafe vehicle.

Just before I was completely stopped at a red light, the engine died, the transmission shifted to park, and the emergency brake was set. After several minutes and several attempts, the engine started and I was able to drive it home. The only indication something was wrong was the “Check Engine” light was on. That light was off the next morning. I took it to the local Ram dealer to be checked out. The result of the computer diagnosis was “Nonplausable codes.” They said there was nothing they could do. Our fear was (and remains) is that this might happen again while driving at a higher speed in heavy traffic. That could possibly cause serious injury or death, or both. Due to that serious concern, we took it back to the dealer and ask them to keep it for a while to see if it happened with them. While they had it, different personnel drove it over 400 miles, but the problem was not reproduced. Also, no recall has been issued for this model truck. However, there has been a recall for other models with the Etorque engine because of unexpected stalling. We are concerned every time we drive it. In fact, my wife will not drive it nor take the grandkids anywhere in it.

Check engine light blinks on and off intermittently, vehicle shakes and feels as if it’s going to stall. From time to time when going to accelerate I pulled out on a main roads and the vehicle lost all power my kids and I flew forward. While idling at a red light, the vehicle started to shake as if it was going to stall and jerked forward and hit the car in front of me. I brought this to the attention of the dealer. I purchased it from and They stated they cannot find any issues. I have pictures and videos of the check engine light coming on in intermittently. I also called when it lost power, pulling into the intersection. This all should be recorded with Jerry Ulm dealer in Tampa.

Four times the truck has powered down while driving - all were when slowing to turn. No prior warning lights or out-of-spec conditions - battery level reading normal prior to shutdown. Truck shut down the engine automatically. Restarting the truck prompted the battery light but no check-engine light. Emergency brake auto-deployed, stopping the car. In all cases I was stopped in traffic (most recently while crossing a highway), but no accidents. Truck is currently at dealership for diagnostics - preliminary code investigation appears related to the auto-start system causing the engine to shut down. Per dealer, they require input from RAM engineering.
