2019 Ram 2500 ENGINE,FUEL/PROPULSION SYSTEM

On June 26, 2024 during a long road trip, the vehicle lost power repeatedly in the middle of an area with no road service. It put my safety and that of my passenger at risk on the highway as losing power suddenly causes danger in fast-moving traffic causing the risk of potential collisions with other vehicles. There was no warning lamp indicating the failure would occur. To this date, the dealer has not fixed the issue. After approximately three weeks, I picked up the vehicle after it as allegedly repaired (at that time the dealer stated it was an electrical issue). The vehicle failed again not more than one-half mile from the Omak Dodge service center placing my safety at risk yet again. I managed to get the vehicle back to the service center at which time, the dealer stated after consultation with RAM technical support, that the issue was a failure in the fuel system. The dealer claims that the problem was the failure of a fuel injector/pump that caused particulate matter to contaminate the entire fuel system. Being that it was allegedly a power train failure, it was to have been covered under the power train warranty. After approximately three months of delay, the dealer stated the truck was repaired. On arriving at the dealer to pick up the truck, the dealer stated it wasn't repaired and had an exhaust issue. The truck remains at the dealer to this date, October 25, 2024. The dealer states that the exhaust issue is yet another issue with the truck that is covered under a warranty voluntarily extended to 10 years by RAM.

I’ve been waiting for a recall fix for the Y78 on my Ram Cummins. My dealer keeps saying they only get in a couple of the high pressure fuel pumps every few weeks. I’ve started the process back in December with no estimated wait time other than it will be many months before they fix it. I know many people who have but a direct replacement pump that will remedy the problem and have been reimbursed for parts and labor. My really helpful dealer this morning told me to contact NHTSA and file a complaint about how to go about the reimbursement process to get it fixed myself or provide me other options to get it fixed. Any help would be appreciated.

My truck began idling hard and stalling out. I've contacted the local dealership multiple times to have the recall fixed for the CP4 fuel pump replaced and software updated and keep getting told they don't have the parts. I'm now having to schedule to have the truck looked at out of my pocket.

I have been having issues starting my truck when I took it in they said it was an ecu reflags needed. I believe it is an open recall y78 for over a year and they do not have the part. But my truck all of a sudden loss power on the freeway doing 65 my wife and daughter started crying I barely made it to the edge of the freeway with being hit within inches of a semi truck. We sat on the side of the freeway with trucks passing us shaking our truck from the wind. Finally I had to call Chp to have cars slow down when it became night time I fears for the safety of my wife and daughter. Yes the issue now is it won’t start at all but they are telling me go somewhere else it could take 2-3 months to fix the issue. No one inspected it yet just that it wouldn’t start. It was continuously having power surges but too light. Then all of a sudden loss power and it says service exhaust system see dealer.

Issue with high pressure fuel pump and loss of turbo boost. At first Mopar/ Dodge refused to replace the fuel pump regardless of the recall. After hours on the phone they finally agreed to replace fuel pump but said no idea why turbo isn’t working correctly.

I STARTED MY PICKUP AND PULLED OUT OF GARAGE PUT IN PARK TO CLOSE MY GARAGE DOOR AND WITH 2-3 MINUTES AT IDLE, SMOKE WAS COMING INTO THE CAB, GOT OUT OF VEHICLE AND OPENED HOOD AND FOUND FLAMES COMING FROM FUEL INJECTION PUMP AREA, WAS ABLE TO GET FIRE OUT BEFORE IT BURNT THE TRUCK COMPLETELY.

Engine started to slip or misfire. Became worse and then light came on saying Exhaust Emission Service was needed. The truck lost power as it limped to the side of the road. The Service Electronic Ignition light then came on and truck turned off. Would not crank again.

TRUCK MAKING TICKING NOISE FROM ENGINE FROM FUEL PRESSURE PUMP CP4?? MAKES NOISE AT IDLE AND WHEN IN MOTION SOMETIMES JERKS AND STALLS

TRUCK HAS CP4 FUEL INJECTOR PUMP. PUMP CAN FAIL WITHOUT WARNING. WHEN IT FAILS THE PUMP DISTROYS THE FUEL RAIL SYSTEM. TRUCK CAN THEN LEAVE THE OCCUPANTS IN A DANGEROUS SITUATION. WHEN PUMP SHUTS DOWN THE ENGINE YOU LOOSE STEERING AND BRAKES. YOU ALSO LOOSE THE EXHAUST BRAKE FEATURE. HAS NOT HAPPENED ON MY TRUCK. THESE PUMPS WILL FAIL AT SOME POINT.
