With 20k miles the High-Pressure Fuel Pump blowup in middle of the freeway in NY. This part name is CP4. My truck subtlety stops in freeway in very dangerous situation. My luck is I had a State Patrol few cars back and he help me to safety the area and wait the tow. My truck stays 2 months parked on at Dealer to fix. The reason is they don’t have a new CP4 to replace is because all 2020 diesel Ram trucks had the same problem. 5 months later my CP4 blowup again with 49k miles now my CP4 and my Tank Fuel Pump breakdown in same time. More 2 months to fix.by the way my truck don’t had 9 months old and stay parked on dealer for 4 months. I paid 4 months of car payments and insurance for not use the truck. Other point is my braking pads. I replaced my front braking pads and rotors with 29k miles. This is unbelievable all my trucks I replaced this part between 70k and 90k. I paid $900 and I believe that my truck had something wrong with braking system also. Like I explained before. In both situations my CP4 subtlety blowups and stop my truck in middle of freeway. Truck engine shutoff and in 65 mph freeway this is very dangerous. God save my life in both situations because all the tomes someone come to help me. First time was State Patrol the second time is Highway Patrol in CA. Yes the problem happened 2 times and my truck in lees the 1 year stay parked on dealer for 6 months. With breakdowns in CP4, EGR, ECM, Tank Fuel Pump, Turbo Actuator and a lot leaks and gaskets breakdowns. My truck has now 1 year and 2 months old and stay on dealer for next two weeks to replace the Turbo Actuator. Just take a look on google and you guys gonna see a lot complaints. A lot! I don’t know. They replaced the component but stills breakdown. Every 3 months my truck stays on dealer for 2 months for fix. Last time I pickup my truck at dealer and next day it breakdown again with a different part problem. Actually my trucks stays with check engine lights on for 8 months.

My truck like all 2019-2020 trucks have the plagued CP4 pump that could fail without showing any symptoms. FCA has failed to step up and have ownership and integrity on this issue. I have asked multiple times to RAM Cares and all I have received is cookie cutter answers from them. I do not know if mine will be next to go or ever will go but FCA has a solution in the 2021 HD Ram trucks and that is the CP-ISB21 fuel pump which looks like the old reliable CP3 fuel pump. Companies out have a solution and that is the CP3 swap but it voids the warranty on the vehicle. The warranty is what is holding me back from having the CP3 pump swap done. Can you please pressure FCA to step up have integrity to replace the plagued CP4 fuel pump with the CP-ISB21 pump. I have challenged FCA on their integrity and ask them if they have it because of the cookie cutter answers I have received from them. I have even asked them to look up what integrity is and to follow the integrity example from the Naval Nuclear Power Program because that program is built on integrity. That program has safely steamed on Nuclear Power for over 60 years. Please again force FCA’s hand on this because this is unsat of them. Look at the forums online and you will see people posting their trucks that have a failed CP4 pump. With that failure FCA is just replacing it another CP4 pump. Also people’s HD rams are down for weeks up to months waiting on the repair. I have also talked to dealership service managers about this issue and they are stumped on why FCA has not issued a recall. Thank you.

I am one of the many 19-20 hd ram owners out there that have the plagued bosch cp4 fuel pump. It is essentially a time bomb waiting for off because when it goes it send metal throughout the fuel system making the vehicle inoperable. That is bad especially those of us that tow heavy. I have asked ram multiple times on when they plan to help us 19-20 owners out and I keep getting a cookie cutter answer from them that nothing is in the works even though the 2021 model hd rams have the reliable cp3 fuel pump and it is a direct swap out. Luckily nothing has yet happened to my vehicle but I worry when I drive towing our home around, full time living in an rv, that the fuel pump will grenade itself. When that fuel pump goes about half of the time the dealerships are not honoring the warranty claim because they blame it on bad fuel but how can we control if the fuel we get is bad or good, specifically water in fuel. Owners are being stabbed with a 10k to 20k repair bill to replace the entire fuel system. Please force ram to issue a recall to replace the cp4 pump with the cp3 pump so that we do not drive around with a plagued fuel pump anymore. Tell them to do their job because you expect me to do mine. I am nuclear propulsion plant operator/supervisor for 20 plus years in the navy and we scrutinize everything to ensure safe and reliable operation of nuclear propulsion plants.

I bought my truck just over a month ago and was told I had to add lubricant to my fuel in order to keep my fuel pump from blowing up, as well as only put in 'good diesel.' I know diesel can change from one gas station to another, but to add a lubricant in order to keep my fuel pump from blowing up on and brand new $80000 truck! All because of the cp4 that ram decided to use for two years, then went back to the cp3 in 2021. Thousands of people have having their pumps blow up in the first 10000 miles, being left stranded for months because they have to redo the entire fuel system at a price tag of $17000. I have had surging issues that are making me nervous to the point that I'm willing to take a $10000 loss on my truck and trade it in for a different one. I don't want to be left stranded on the way to work one day because fca doesn't want to recognize they put in a defective part that is cause catastrophic failure and leaving us consumer out of a vehicle for months. This has to change!

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 federal safety agency needs to force fca to recall these trucks.

I was towing my 5th wheel trailer from rancho cucamonga to san diego. When I was driving on I-15, almost nearby exit 15. Suddenly there is a error on the screen , said 'exhaust brake system failed , ask me go to dealer'. Then I found there is no power anymore . I tried to press the pedal again , still no power. Then I rolled over to the side of the freeway. When the speed came down to about 15mph, the engine stopped. Then I pooled over , and tried to restart it . Nothing happened. I can hear it trying to start, but no start anymore. Then I called roadside department to tow my truck and trailer away . It took 6 hours to find the tow company, but still didn't come. Then I paid the tow company, then they came to save me and tow my truck to the dealer.

I purchased a knew 20 ram 3500 and all though I haven't had the issue happen to me yet, I'm a nervous wreck that it will and my family and I will be stranded. There are hundreds if not thousands of people having experienced a catastrophic failure of the fairly new cp4 fuel pump. When this goes, it takes out the whole fuel system resulting in $17,000 worth of damage. What's worse is that your stranded ,with out a vehicle. Dealerships are only doing a limited amount of loaners but not a vehicle equal to what you had. Some have waited for months and fca doesn't appear to be doing anything to correct these issues. Some of us travel hundreds of miles at a time with an rv in tow that is a considerable amount of weight. Quite often when you travel, there is nothing around or place to coast to, or even in the most best areas. The cp3 was proven equipment that worked well and while I understand and encourage the advancement of technology, you have to be willing to acknowledge a problem when you have one, especially what could result in a safety issue. These cp4 fuel pumps need to be recalled untill further research is done to correct the ongoing highly expensive issue that is putting all 2019 & 2020 vehicles with this pump at a safety risk within a rapid rate of only under 10,000 miles and or less. Ignoring the problem and doing nothing is irresponsible and negligible. The anxiety that this is causing my family let alone all the others, is very mentally and physically taxing on one's life. Please investigate this and help all of us involved get a little piece of mind and a more reliable product than the cp4, that is almost guaranteed to fail within a short amount of time.
