In November 2020 the high pressure fuel injection pump failed on my truck while crossing a four lane intersection. The pumpwas confirmed failed by dealership service shop. Had a check engine light and service exhaust system warning just before engine shutdown and truck was disabled in middle of intersection.

I was pulling a 10k lb trailer from California to Arkansas. While passing a semi truck my vehicle lost engine power and left me without power steering or brakes. I was luckily able to make it to the right shoulder, vehicle would not start. Dealership found the Bosch CP4 injection pump to have failed at 15,000 miles. I am lucky to have been traveling in an area of Texas where I did not have too much traffic or this even could have been much worse.

Fuel pump is not good and is a safety issue that can lead to complete engine failure and possibly a crash.

We were traveling SE on I-30, in the passing lane, doing approximately 75 MPH when the vehicle started shuttering. It was subtle at first, then became more violent. The engine lost power and we had to do an emergency lane change with no engine power, no power steering, no power brakes. We then coasted to the shoulder with traffic passing us and behind us speeding by. Luckily we were near an exit and we barely had enough momentum to get away from traffic. We were lucky to change lanes and exit without getting into a collision with other traffic because we went from highway speed to slow very quickly and had to change lanes and exit. It was the high pressure CP4.2 fuel pump failure the dealer eventually informed us. They also said this is a common problem and they had several other failures just like this.

I was driving on the freeway when the truck suddenly began surging the throttle. I began to make my way to the shoulder. By the time I was in the shoulder the truck lost all power. I came to a stop and the engine began shuddering and bogging down before I was able to safely shut it off. Fortunately traffic was light and I didn-??t have a trailer, this could have been very dangerous had I needed to accelerate and lost all power to the truck. Dealer diagnosed with a failed CP4 injection pump, a know issue for this model year.

I was traveling and around 655 miles from home. My truck was idleing and started making a loud knocking noise. I turned it off and then it wouldn't start again. I called Chrysler roadside assistance and had it towed to the nearest dealer, bluebonnet Chrysler Dodge and Ram. After my vehicle sat there for 4 days, they finally looked at it and determined that my CP4 fuel injector pump had failed. It is all covered by warranty, but now I'm 655 miles from my truck with nothing to drive.

Truck died in traffic. Lost all power steering, brakes, etc. Almost caused a multiple vehicle accident, and left me stranded in the middle of traffic until I could get assistance to move. There was no warning or notice before the truck just quit working. A warning light came on after the truck died and stated "exhaust system failure. See dealer immediately".

Fca switched from proven CP3 fuel pump to a CP4.2 for model years 2019 and 2020. They have now switched back to CP3 for 2021 due to number of failures. When it fails it takes out the entire fuel system and it cost 10K for repair. My complaint is that they should recall the fuel pumps on the 2019/2020 Ram 2500 models. It is the right thing to do.

Losing power while driving down the road. Losing power when pushing on gas pedal. Makes awful noise when starting. Almost sounds like a bad starter

The 2019 to 2020 model year Ram 2500 heavy duty equipped with a 6.7L cummins diesel engine has a major safety issue that could cause a stall and increase the risk of a crash. The Bosch CP4.2 fuel injection pump has a very high rate of sudden failure leading to immediate stoppage on the engine and engine braking system. The pump destroys itself and takes out the rest of the entire fuel system leading to repairs in the $20,000 usd range. Fca & Ram have attempted to revise the pump in late (July) 2020 to solve the issue but the failures keep occurring. For the 2021 model year, fca & Ram have changed the pump entirely and reverted back to using an older, safer, more reliable design. No public announcements of neither the pump revision in 2020, nor the pump change in 2021 have been made. The issue is so prevalent that the replacement pumps and repairs generally have a 30-90 day wait period where the customer is without the primary vehicle. This problem is a substantiated safety risk. According to a Texas judge in a Bosch CP4.2 lawsuit, when another automaker, GM tried to dismiss the case saying the pump failure is not a safety issue, the court responded: "the worst case scenario of a truck spontaneously stalling at high speeds is not a mere inconvenience. Nor is it a mere inconvenience to spend between $8,000 to $20,000 on repairs to make the trucks fit for their ordinary purpose. The court rejects GM's suggestion that the risk of spontaneous engine failure while driving is not, as a matter of law, unreasonably dangerous, depriving the vehicles of fitness for their purpose of transportation.". Toyota agrees: "if a vehicle stall occurs while driving at higher speeds, this could increase the risk of a crash". fca & Ram have remedied the situation for the 2021 model year however, the 2019 and 2020 owners are still at risk. The NHTSA needs to force fca to recall these trucks.

This is the worst truck I've ever purchased, a simple fix needed to the pulley tensioner and the clutch fan is needed..been to dealer twice going a 3rd time. The fuel pump CP4 is a danger to drivers and pedestrians as these trucks are meant for pulling heavy loads and mostly on interstates which makes it a danger. The CP3 is needed back in the trucks as there is a horrible fuel pump chatter at this point and an iminant failure is coming soon. Also the truck rolls in park like 5 feet for no reason while off in park

We were just leaving the desert after a weekend trip when there was a weird noise from the engine area. As I opened the hood and the truck died and never started back up. The truck was towed to local dealer which is 350 miles from home were it sat for 7 days until we could make it back out there. My trailer was also towed and I had to use a friends truck to get it. Then stopped by the dealer to find out what's going on. Fuel system shot. 15,838 for repair. Now my truck is a 2020 Ram 2500. Purchased in August 2020. 4,900 miles on the odometer. Haven't even had my first oil change yet. Dealership said they found red dye diesel in the system so fca does not want to cover the charges. I have done research on this and have found nothing harmful about red diesel. So unless they change their mind it looks like a lawyer is next.

I was hauling a 24' enclosed car trailer from san diego to las vegas. It was loaded with a car that I had just picked up from the painter and was looking forward to getting it back home. As we were going through the victorville area on interstate 15 the engine appeared to have a misfire or stumble. Shortly after that an alert message appeared on the dash regarding an exhaust emission service was needed. Shortly after that the truck started to lose power and another warning appeared regarding a service electronic ignition was needed and then the truck went into limp mode. I was able to get across three lanes of freeway traffic before barely being able to make it off the freeway. I was able to find a relatively safe area to pull over and turned the truck off. It wouldn't then restart so we were stranded about 200 miles from las vegas.
