The contact owns a 2019 Ram 5500. The contact stated that while driving at an undisclosed speed, the vehicle stalled. The vehicle was towed to a certified mechanic to be diagnosed. The mechanic associated the failure with the diesel pump. The mechanic informed the contact that the diesel pump was previously replaced with a generic part.

The failure mileage was approximately 110,000.

The DEF system failed on this truck at the end of 2025. The truck has entered limp mode, and if we continue to drive it, it will shut down completely. The vehicle has been at Darling's RAM in Ellsworth, ME since March 2026, and they say that they are still waiting for the parts. Why aren't parts available?? They have no idea when parts will be shipped from the manufacturer. Why is this at all acceptable?? I am running a business, and I am having to cancel orders from my customers because Stellantis is not sending the parts. This makes the vehicle unsafe to drive, and I feel that this is unacceptable.

I would like to report a major safety concern with the push button start system and programming on the 2019 and up 5500 cab and chassis with the 6.7 Cummins. On November 29th we had a 2019 Ram 5500 that went in the ditch and ended up on its side because of soft ground. It was laid fully on the passenger side. It was still running. Operator tried to turn off engine and it would not. After he climbed out drivers side window he tried to clamp off fuel line. Truck continued to idle until it stuck a few of the main bearings to the crank shaft . truck was towed in and all fluids were checked and filled as needed. Turning the engine over with a barring tool was I was able to free it up. I charged batteries and turned on key it wouldn’t crank. (shifter was in park when unit was unloaded off wrecker into shop) PCM has numerous codes including lost communication with TCM. Didn’t display gear selecting in cluster. After clearing codes truck would start and run. These chassis’ will not turn off if the transmission dash display does not display park or neutral and will not turn off if PCM loses communication with TCM even if transmission is in park or neutral.. Luckily this was not an accident were anything started on fire but chassis should either have a impact or tilt sensor or programmed so if you hold start button for a certain amount of time or press it a certain number of times it overrides ignition system. A mechanic with a 2019 2500 with the Cummins says that his manual states that it button is pushed and held it will turn ignition off after holding for 5 seconds. I test a couple of other 2019 5500”s that are located here and with transmission in drive, vehicle stopped motor running have held button for up to 3 minutes and pushed it up to 30 times and ignition will not turn off unless dash display shows park on neutral. If there had been damage to fuel lines it could have been pumping diesel fuel onto the accident scene

The contact's husband owns a 2019 Ram 5500. While her husband was driving 45 mph, he heard an abnormal sound coming from the engine as the check engine warning light illuminated. The vehicle stalled while depressing the accelerator pedal. Her husband pulled over to the side of the road and upon inspection, he discovered that smoke and a fire had started in the engine compartment. Her husband grabbed the fire extinguisher and extinguished the fire. The contact owns a towing company and was able to tow the vehicle to a dealer. The dealer informed the contact and her husband that a rod had gone through the engine block. The contact and her husband were provided an estimate for the repair which they declined. The contact had the engine replaced by an independent mechanic. Upon investigation, the contact discovered the vehicle had been placed under NHTSA Campaign Number: 21V439000 (Engine and Engine Cooling) which she linked to the failure. The manufacturer was notified of the failure and the contact was initially provided a case number. The contact then received a call from the manufacturer that her claim was denied. The vehicle was repaired. The failure mileage was 164,716

While unloading cargo, I was standing on the flatbed of the truck, leaning over the standing side-gates, without realizing they weren’t locked in place. The gates fell down onto a co-worker and I fell out of the truck. Similar incidents have occurred before and after this accident. These gate latches don’t have any warning systems in place to indicate when they are unlocked. It is unknown if this component has been inspected by others.

The transfer case shifted itself into neutral while driving on the highway. It wouldn't go into any other gears and it lost all functionality. I wasn't under load and had been maintaining a set 65 mph. There was no warning the RPMs just redlined. I set the vehicle into what registered as park and when I got out it continued to roll towards me. I had 3 small children in the vehicle at the time and had we not made it off the highway in time I hate to think what could have happened. I am a mechanic by trade and it is the only reason we were able to get it to a safe area.
