2020 RAM 3500 Engine Problems

Codes: P2002, P242F, P2463, P1451 Failures: DPF, Charge air cooler leak, PM sensors, EGR internally cracked, Catalytic Convertor, Pink tinged oil, strong diesel odor in oil - post failures. Erratic def gauge readings, unstable idling, clunking downshift when exhaust brake decelerates, warm up stumbling. Power reduced, see dealer (over and over and over and over). Limp Mode (5 MPH). Permanent ticks/taps from front left motor, front passenger wheel well, passenger side mid-truck. Extremely loose gear shifter plus an occasional “Vehicle Not in Part” message on the dash display. Manufacturers Service Center (local and ONLY Ram dealership) has reproduced the issue. Independent Diesel Mechanic shop also reproduced. Service center and Independent shop both inspected. The safety issues of a 5 MPH limp mode and risk of sudden engine stalls while driving in traffic, especially on an interstate should be fairly self explanatory… As is a constant “Power Reduced See Dealer” problem,...

Reoccurring messages regarding DEF, Exhaust Regeneration, and DPF, causing more and more frequent ReGen for longer and longer. Numerous trips to various Ram dealerships resulting in codes being cleared and then being told it was a software issue. After 2 years of this intermittently happening, we experienced an extended Regen that lasted hours and did not clear out the error code. Ram dealer in Utah charged $280 to do a stationary regeneration and once again clear out codes. Less than 6 months later with more and more Regens, a failed regen sent truck into Low Power Mode (losing the ability to tow or excelerate quickly). We ended up having to take it to a Ram dealer over 2 hours away in S. Atlanta to have them take it apart and tell us that the factory installed wiring harness rubbed a hole in the charged air cooler boot which was then...

On 12/4/23, at 6:37 am PST, we initiated remote start via the key fob. At 6:40 am pst, a flash and fire erupted from under the hood of the truck. We immediately worked to control the fire using extinguishers and garden hoses until the fire department arrived a few minutes later. They worked to put the fire out that engulfed the engine compartment and then worked to get the hood open to finish putting the fire out. The fire didn’t fully go out until the battery cables were cut.

As I was driving the vehicle caught fire and I lost brakes. The vehicle had to be put into a retention pond to stop it.

While driving Down a paved roadway on 6/30/23 @ 5pm doing approximately 20 miles per hour the vehicle died and the dash lite up with every single message possible such as 4WD inactive, oil change due, fuel filter service required and etc. Attempted to restart the vehicle for about 25 minutes when another citizen noticed we were having issues with the vehicle so they stopped to assist us. The citizen towed my vehicle to location we were staying at for the weekend and upon arrival to the location I disconnected both battery terminals to allow the computer modules to drain/reset. After allowing the batteries to be disconnected for several hours I hooked them back up and tried starting the vehicle and was unsuccessful getting it to restart. I disconnected the batteries again for the night and returned the next morning to hook them up. after hooking the batteries back up,...

My high pressure fuel pump went out while I was towing the 43 ft enclosed trailer causing the engine to shut down. I was able to get it home and onto a car hauling trailer took it to a dealership and confirmed the high pressure fuel pump was the culprit they informed me that they would not perform the safety recall because of a modification to the vehicle which has no bearing on the safety issues at hand I contacted FCA they encouraged me to take it to a different dealership which I did. I had to pay a tow truck to haul it to another dealership in which they told me they would do the recall however when they put my VIN number in their system my pickup had been blacklisted by the parent company Chrysler saying do not work on this vehicle for safety recalls. I at this...

As of today, manufacturer/dealers have failed to comply with repairs based on national recalls. On several appointments, the parts are never received. Manufacturer and dealers are not complying with mandated recalls. Please take action!

I am attempting to get recall 21V-880 done. This is a safety recall where failure of the engine could result in a crash. I contacted my local dealer and they state repair parts are only available in limited quantities. They put me on a waiting list and stated there are 105 vehicles ahead of me and they don’t think they will have the parts to repair the safety recall until late 2023. This is completely unacceptable for a major safety recall.

The contact owns a 2020 Ram 3500. The contact stated while driving 5 MPH, the oil pressure warning light illuminated. The contact then drove back to his residence. Upon opening the hood to check the oil pressure, the contact noticed that the oil consistency was like jelly. The vehicle was towed to the dealer where it was diagnosed that lack of engine oil, caused engine to cease and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and a case was opened. The manufacturer then followed up with the dealer who provided an estimate for the repair. The manufacturer informed the contact that the engine replacement would not be covered under the warranty however, a vehicle buy back would be considered. The failure mileage was approximately 140,867.

0N 4/4/2022 while traveling on interstate 64 E in WV ,towing an R V camper , no warning signals on the dash screen, my truck started losing power and went completely dead,just missed by a tractor trailer rear ending me, as I rolled off to the side of the road. Iwas towed to the nearest Dodge dealership. When I arrived at the dealership a mechanic came and open the hood, he found diesel leaking and a metal rod of the camshaft sitting on top of the engine, which he stated shot through the engine block. Warranty company doesn't want to tear down engine after I gave approval to investigate issue. This is my work truck and source of income. Four weeks later, I am not getting help from dealership that sold me the truck and warranty. Warranty company is trying to use loop hole to get out of paying. I...

Truck was with high pressure pump issues, spent $2600 in rental truck, $400 i. Towing truck and about one month with no truck, Chrysler still doesn't want to pay me back, this is my second truck with same issue, previous truck was a 2019 3500 ram having the same problem when truck was with only 4,000 miles on it. Now they repaired my truck but now i feel like my truck lose already torque, is using more diesel and more DEF.

I was towing a light trailer (4000 lbs) on I-5 in Oregon on 10/22 when I slowed from ~58 mph to about 45 mph to allow a hasty SUV to merge from the right. When I tried to resume speed the truck seemed "stuck" at 45mph for quite some time. I gave it full throttle and it didn't accelerate. I tapped the brakes, turned off cruise control and it felt like there was no power at all, like it was freewheeling. Finally the motor 'caught' and it accelerated to highway speed. I looked for the problem online and believe this may be related to the CP4 fuel pump issues. Is it safe to continue driving or should I take the truck to a dealer or what? There is no recall yet and I hear the dealership people are telling owners that it is from bad fuel and not covering it!...

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....

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...

WE WERE DRIVING OUR 2020 RAM 3500 DIESEL WITH A 2000-POUND TRUCK CAMPER IN THE BED ON A CITY STREET ATTEMPTING TO MAKE A RIGHT TURN THROUGH A YIELD SIGN WHEN THE ENGINE SUDDENLY STOPPED COMPLETELY WITHOUT THE ABILITY TO RESTART IT. THIS RESULTED IN SUDDEN LOSS OF ACCELERATION, POWER STEERING, AND POWER BREAKS, LEADING TO A NEAR COLLISION WITH A LARGE POLE AND POSSIBLY OTHER VEHICLES IN THE IN THE INTERSECTION. ALTHOUGH WE MISSED THE POLE AND OTHER VEHICLES, IT WAS EXTREMELY DIFFICULT TO AVOID DUE TO LOSS OF POWER STEERING AND BRAKING. HAD OUR SPEED BEEN SLIGHTLY HIGHER, A COLLISION WOULD HAVE BEEN UNAVOIDABLE. AFTER HAVING OUR TRUCK INSPECTED BY THE DEALERSHIP, IT WAS DETERMINED THAT THE CAUSE OF THE ENGINE BREAKDOWN WAS THE BOSCH CP4.2 INJECTION PUMP CATASTROPHICALLY FAILING (OR "GRENADE-ING" OR "IMPLODING" AS THE DEALERSHIP PUT IT) RESULTING IN THE COMPLETE DESTRUCTION OF THE ENTIRE FUEL...

TRUCK CAUGHT FIRE IN ENGINE COMPARTMENT. I HAD JUST GOTTEN ON THE FREEWAY AND REACHED 70MPH WHEN I COULD SEE SMOKE COMING FROM THE ENGINE. PULLED OVER AND IT QUICKLY BECAME ENGULFED IN FLAMES. STATE FARM CLAIM 28-18Q6-12R ELIZABETH ANDERSON, CLAIM SPECIALIST, 844-292-8615X2539126712

WHILE DRIVING AT HIGHWAY SPEED A ROD CAME THROUGH THE ENGINE BLOCK. I WAS FORTUNATE I WAS ABLE TO COAST TO THE SHOULDER OF THE HIGHWAY BEFORE COMING TO A COMPLETE STOP. I WAS TOWING A TRAILER. THE ENGINE GAVE NO INDICATION ANYTHING WAS WRONG. THE ONLY NOTABLE THING WAS THE LOST OF FUEL MILEAGE THAT BEGIN TO DECREASE EARLIER IN THE DAY. THE RAM ENGINEERING DEPARTMENT IS HOLDING UP THE DEALER FROM REPAIRING THE ENGINE. THEY ALSO HAVE ANOTHER THERE WITH A SIMILAR ISSUE. THEY CAN'T PROVIDE A TIMEFRAME ON WHEN THE REPAIR WILL BE DONE. NO RENTAL OR LOANER VEHICLE IS GIVEN. THIS IS MY WORK TRUCK AND NO INCOME WHILE THE TRUCK IS DOWN.

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.
