Def pump failed twice with this vehicle and with that it does not allow the vehicle to run any faster than 5 mph after the countdown ends. Unknown how the exhaust being plugged and service was done to clean the exhaust ended up having the fuel pump and turbo charger needing replaced. Not sure if they went hand in hand and one causing the other. So far the vehicle only has almost 78,000 miles on it. Change oil and fuel filters at the vehicles scheduled computer system reports on the vehicle. I was having issues from service center having trouble resetting the exhaust system, which they said the system was not sealing properly. Took them a couple of days to get part from dealership to get it to seal and reprocessed the test which they said passed exhaust reset. That would explain the poor fuel rating of only getting 9 miles per gallon. If there was a complete fuel pump failure, not sure if that would compare to this being a safety issue. Not sure how engine would react, due to it completely failing or if the turbo would cause the vehicle to be unsafe. The vehicle is currently at dealership and only 1 out of the 3 are even available to fix this problem. Def pump is available, but unknown when the others will arrive. Service shop said it could be 3 weeks or 8 months for parts to come in. Due to being a back ordered item. Spent $70k for this vehicle, just to have it spend over 2 months in the shop. I do my own oil and fuel filter changes, due to it being faster and cheaper than any dealer or shop.

Subject: Fuel System Failure Resulting in Engine Damage – 2020 RAM 2500 Pickup VIN: [XXX] Complaint Summary: I am submitting this complaint to formally report a dangerous and costly fuel system defect in my 2020 Dodge Ram 2500 Pickup (VIN: [XXX] ) that has resulted in catastrophic engine damage. Although Chrysler has issued a recall for the high-pressure fuel pump (HPFP) in many 2020 Ram trucks equipped with the 6.7L Cummins engine, I was told that my vehicle was not included in the recall—even though it exhibits all the classic symptoms of HPFP failure. This is a safety hazard and a potential emissions violation. Details of the Incident: In June 2025, I brought my truck to Tracy Chrysler Dodge Jeep RAM after experiencing engine misfires, loss of power, and a knocking noise. The dealership diagnosed a P0303 cylinder misfire and noted a fuel smell in the engine oil, as documented in repair order #[XXX]. Despite extensive diagnostic work—including compression tests, leak-down, and injector swaps—the misfire remained unresolved, and a tapping noise persisted. The technician explicitly noted fuel contamination in the oil and suspected internal engine damage due to a fuel system issue. To further investigate, I submitted an oil sample to Blackstone Laboratories. The lab confirmed the engine oil was heavily diluted with diesel fuel—over 10% fuel contamination, which reduced the viscosity from 5W40 to the equivalent of 5W20. This is consistent with HPFP failure leaking fuel into the crankcase. The oil report also noted excessive steel wear and recommended immediate oil change and fuel system inspection. At no time was a check engine light present, nor was there a clear diagnostic code for HPFP failure. Chrysler continues to deny responsibility even though the evidence clearly points to a failed HPFP—a well-documented issue for this engine model and year. The cost of diagnosis and parts alone has exceeded $4,000, and the engine is likely destroy INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA

ENGINE

Vehicle randomly shuts off during normal operation. Same as if the Start / Stop button were activated. Vehicle coasts until it self applies the emergency brake at about 3mph causing a sudden, jerky complete stop. Switches itself to Park. Dash indicates “sterp on brake to restart”. Vehicle restarts normally but may randomly shut down again. Safety risk is loss of steering, loss of power brake control, and total loss of power in traffic. Taking it to dealer today. Vehicle has not been inspected by anyone yet. No messages or warning lights display. This is a recent problem but recurring with increasing frequency.

I have a check engine light that came on. I took it to the dealer and they said it is a P0542 code for heating element relay. There is a technical service bulletin out for this known issue. I still have power train warranty left on my truck but they’re claiming it isn’t covered. I went as far as to add a bank ram air intake for over $1000 to help eliminate a complete engine failure. Any help would be appreciated

My name is [XXX]. I have a 2020 Ram Laramie. I purchased the truck June 2nd 2022. So then, my truck did not come with a fitting spare tire. Currently I have 40/13.5r17 on the vehicle. That the manufacturer placed with this truck when I purchased it. The spare that came with the truck, is a 18 inch spare. That doesn’t fit my truck. Also it’s a major safety hazard. My left front tire split on the side so I went to use my spare and it was a wrong tire. Also, I purchase the vehicle with only 17000 miles on it, and No personal owners. Only dealerships. I paid $135,000 cash for it on the spot. Only had it 1 year. Also, now my truck won’t start. Something is wrong with my fuel pump and batteries or something. There suppose to come get it today. I live 30 miles up the mountain in WA state. So I do not do a whole turn of driving. I’m not sure what’s wrong, but I’m kinda stuck without a vehicle now, til it gets fixed I suppose. But I thought I’d let you know, so you can double check you guys products and make sure there now like expired parts or something. Thank you and have a nice day.

RECALL IS NOT BEING COMPLETD IN A TIMELY MANNER. We have not had any incidents but we have been waiting since August of 2022 for the dealer to receive the parts to complete the recall. We have been told that we are on a waiting list and we're actually on the waiting list at 2 different locations. I read online that I should file a complaint if the recall is not completed in a timely manner. We are driving the vehicle with the risks these recalls pose and do not want to have to go through any incident or accidents.

See dealer exhaust system exhaust required was on the display. This happened with me , wife, 2 year old and 6 year old in the truck. It just felt and sounded as if the truck dropped gears and slowed down in the middle of high traffic with big rigs on a busy interstate. I put on hazard immediately to warn the trucks behind me. Do to immediate loss of power and limp acceleration. As I tried to assess the situation safely and quickly as possible , I nearly got rear ended by several big rigs as they tried one by one to avoid me at the last second. Me and my family are safe but I am in shock still as we managed to get out of the way regained my composure to get my family safely off to the next ramp when traffic slowed to avoid having my family in high traffic danger. This issue is a severe danger to the general public and anyone in the road with this type of malfunction. I as so many other families who were in the same situation,stranded and barely avoided serious and substantial injuries and death. If this was due to the cp4 system, I would have these rigs of the road asap. I also had the dealership ,before, I left Nevada,to go and get my new concession trailer in Georgia had the fuel filters changed. The oil and filters changed, an update for the truck and asked and arranged for the new cpu unit to be installed. I also asked the dealership mechanic if it was advisable to drive out to Georgia to get my food truck and he said yes. I’m not sure if this is the issue, but my research point to this direction. There are forum on this. With stories like mine and the outrageous safety hazards this has caused. It is a defect that needs immediate action. This defect does not trump my family’s life or any other innocent lives. This puts me and my family out of a truck to get to Georgia to pull my concession trailer back home. We are literally stuck and stranded in Missouri. This defect has put me and my family in a vulnerable position which could be a serious hazard to us thanx

Wanted to explain what happened to the truck. Left the house as normal, pulled out of the driveway. Normal acceleration around 45mph, truck started to spit and sputter making loud knocking noises in the engine. Lost complete power. Truck shut off by itself. Was able to crank back up and drive it back home with vigorously vibrating and sputtering. I was only about 200 yards from my driveway when this happened. Truck is not driveable.

I have tried to get a new fuel pump from the dealer. No such luck yet. Now my truck is not drivable. It has multiple misfires and sounds just downright horrible. This truck has been serviced religiously. I have done everything the truck needs done at the times it needed done. Now the truck again is not drivable. The engine sounds like it is about to blow. I need someone to tell me what I need to do now. I do not have thousands of dollars to put into this truck, all because the fuel pump has not been available.

FCA started a recall in October of 2021 for the high-pressure fuel pump on 2020-2022 Ram 2500 trucks with the 6.7 Cummins turbo Diesel. This recall can and has been catastrophic to the fuel systems and engines. As of 3/30/2022 there still is no remedy. I am experiencing engine shutter and shaking and hard starts on a vehicle with only 24,000 miles on it which i believe is due to the failing fuel system and fuel pump. i would like to know if this recall can be expedited and the problem corrected before catastrophic failure happens.

Summary - 2020 RAM 2500 CP4 Fuel Pump failure We departed on Saturday Oct 16, 2020, for a trip from our home in Raleigh NC to Florida for our 35th anniversary. The truck sputtered then stalled on the side of interstate 95 (southbound) in South Carolina about 60 miles from the Georgia border. We were towed to the nearest RAM dealership (Butler Chrysler Dodge Jeep RAM) in Beaufort, SC. The earliest we could get a rental was the following Wednesday (10/20) so decided to stay nearby at a local beach. We came back through on Friday to finally get our rental and returned home. Today is 11/4 and we still don't have our truck. I was told the problem was the CP4 Fuel Pump. Apparently it disintegrated (their words) and threw metal shavings all through the fuel system. They told me they had to change everything from the fuel tank all the way to the injectors. The last of the parts are supposed to be in later today, so am looking at driving the 5 hours back down to Beaufort SC this or next weekend to pick up the truck depending on when the repairs are made.

I was driving my truck on 10/26 approximately 9 am when the engine made a loud knocking noise and then proceed to make a erratic clanking noise. The truck proceeded to completely shut off while driving, rendering me unable to control the vehicle as all systems shut down. There were no warning lights present or any other warning signs. It coasted to a stop on the side of the road. The safety of myself and anyone around me was at high risk as I had no ability to control the vehicle. The vehicle only has 12,000 miles on it so I had it towed to the closest dealership, Autostar of Hendersonville NC. It took a week to get a diagnosis because their solitary diesel tech was on vacation. They offered my no loaner vehicle and FCA has not made an adequate offer to cover the full cost of a loaner vehicle. The diagnosis on the vehicle was a high pressure fuel pump failure. I currently have not ETA on parts and no vehicle to drive. It is my understanding that NHTSA is already investigating this issue. Multiple attempts made to get help with a loaner vehicle, an ETA on parts/install have all been met with deflection from dealership and FCA customer care representatives. Any attempt made to inquire if the new fuel pump/system has been adequately updated to ensure this wont happen again has not been answered. Any attempt made to inquire if this issue has cause long lasting damage to the engine has not been answered. This is a serious problem and needs to be remedied. FCA needs to step up and take care of its customers.

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.
