2019 Ram 2500: sudden loss of power

Filed May 4, 2026 · Transmission · NY

The transmission failed. Prior to the failure, the vehicle had an undiagnosed fluid leak believed to be coming from transmission-related hoses/lines. These hoses were replaced; however, the issue persisted and ultimately resulted in transmission failure. The failure occurred while the vehicle was in operation, which caused a sudden loss of power/drive capability. This created a hazardous situation, especially in traffic, as the vehicle was unable to accelerate or maintain speed, increasing the risk of a collision. The fluid leak and subsequent transmission failure were inspected by a service center. The leaking hoses were identified and replaced; however, this repair did not resolve the underlying issue, and the transmission ultimately failed. No indication of symptoms of failure prior.

I have experienced unexpected loss of power during acceleration, lack of exhaust breaking and engine codes p003a and p006f which I believe are associated with the turbo actuator.

Then there was an awful noise from under the hood - it was a now loose pulley and belt.

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.

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.

Driving home one evening and truck started losing power and downshifting and completely disabled on the road. Transmission was blowing fluid out of the dipstick tube and engine was running horribly then died all of a sudden and wouldn’t start back up. Come to find out after having transmission repaired by a shop because Ram refused to warranty it, that the CP4 high pressure fuel pump has Grenaded and sent metal all through my fuel system and my truck is completely disabled with a “void” warranty due to a dealer claiming I didn’t perform a service on my truck that isn’t due for another 17,000 miles.
