FUEL/PROPULSION SYSTEM

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.

ENGINE

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

POWER TRAIN

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.

FUEL/PROPULSION SYSTEM

There is a safety recall on my 2019 Ram 5500 rollback tow truck. The recall number is Y78. On November 17 My truck unexpectedly stopped working on highway M33 in rose city Michigan. I discovered there was a recall on the vehicle for a premature fuel system failure. I called the FCA they told me to take it to Thelen Chrysler Ram in Bay City Michigan. I called Thelen to confirm I could take it there and they said yes. I spent $522 to have it towed there on Friday November 18. I tried to contact the service department and left several messages on the following Monday and Tuesday. On Wednesday I called the main dealership office and informed them that the service dept. was not returning my calls, they hand carried the phone to the very arrogant service dept. manager [XXX]. I informed him about the recall on the truck and he said they have not looked at it yet and that he would get back to me when they had time to look at it and didn’t know when that would be. On the 28th he finally called me back and confirmed my fears that it was a total fuel system failure. He then says that there is a recall for that issue but Ram does not a a fix for it, the 2020 models have a fix for the same problem but not the 2019 models. I told him I need it fixed in a timely manor and he told me that’s not possibly because they take care of their regular customers first and they don’t have the lift equipment to fix it that the mechanic would have to do it on the ground and that I need to take it to a different shop. Here's my complaint: I own a tow company called Local Towing Service,LLC. I depend on this tow truck to make my living. FCA told me to take it Thelen , I called Thelen and they told me to have it towed there, now they are telling me to take it some where else that they can’t fix it but it says on their website that they service Ram 5500 chassis . Ram has a recall for this issue with no fix on the 2019 but they do on the 2020? This makes no sense. They know how to fix it. How can INFORMATION Redacted PURSUANT TO THE FREED
