The contact owns a 2025 Ram 3500. The contact stated that shortly after purchasing the vehicle brand new and filling the fuel tank on December 3, 2025, the DEF depth gauge failed. The vehicle was taken to a dealer, where the module was reprogrammed and the physical gauge was replaced. However, the contact obtained internal service notes revealing that the urea pump, the DEF tank, the urea tank wiring harness, the DEF injector, and the fluid had actually been replaced due to an active fuel leak within the DEF...

system. On March 31, 2026, the vehicle was taken back to the dealer to address a malfunctioning digital rearview mirror. While at the dealer, a recall repair was performed under NHTSA Campaign Number: 25V882000 (Air Bags, Electronic Stability Control (ESC)). The digital mirror was replaced; however, the failure recurred immediately. In May 2026, the vehicle was returned to the dealer for the ongoing mirror issue; however, the service notes only indicated that a part adjustment was performed, and the defect persisted. The contact then took the vehicle to a second dealer to repair the digital mirror and address the DEF system, as the warning light had re-illuminated on the instrument panel. During this visit, the second dealer performed a recall repair under NHTSA Campaign Number: 26V059000 (Exterior Lighting, Electrical System). While the dealer claimed to have serviced both the DEF warning light and the mirror, the mirror failure remained unresolved. After spending a cumulative month at the dealer, the vehicle was diagnosed with an illuminated check engine light caused by a recurring DEF-contaminated fuel leak. The dealer replaced the entire DEF assembly, including the fuel system components, and cleared the DTCs. In July 2026, the vehicle was returned to the dealer yet again for another digital mirror replacement, which failed to resolve the issue. The contact believed there was an inherent manufacturing flaw at the top of the fuel tank causing the repeated DEF system failures. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 1,000.
The contact owns a 2020 Ram 3500. The contact stated that while driving at 65 MPH, the vehicle suddenly experienced reduced speed and hesitation, and there was a rattling noise coming from the engine as the RPMs increased above 1,500. The vehicle was driven slowly to a local dealer, where the contact was informed that the high-pressure fuel pump (HPFP) had likely failed. The exact cause of the failure had not yet been determined, and the vehicle was not repaired. The contact stated that the vehicle was previously serviced under NHTSA Campaign Number: 21V880000 (Fuel System, Diesel) and was experiencing the same failure listed in the recall. The failure mileage was 300,000.
Had recall for high pressure fuel pump completed in 12/2022 and the new part has prematurely failed causing debris to go into the fuel system. The new part was to prevent this issue from happening and it seems that failure after only 3 years means that a defective part was installed or some form of improper installation occurred.
The contact owns a 2021 RAM 3500. The contact stated that while driving at 40 mph, the vehicle stalled and could not be restarted. The vehicle was towed to a dealer, where it was diagnosed that the entire fuel system needed to be replaced due to the high-pressure fuel pump exploding after metal shavings were found throughout the entire system. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 77,000.
The contact owns a 2019 Ram 3500. The contact stated that while driving approximately 55 MPH, a warning light for the exhaust system illuminated, and the vehicle stalled. The vehicle was pulled over to the side of the road, and the vehicle failed to restart. The vehicle was towed to an independent mechanic, where it was diagnosed, but the vehicle was not repaired. An unknown dealer was contacted and confirmed that the VIN was not under recall. The manufacturer was notified of the failure and confirmed that an...

unknown recall repair was previously completed on the vehicle. Upon investigating the failure online, the contact related the failure to NHTSA Action Number: EA23001(Fuel System, Diesel). The failure mileage was approximately 214,000. The VIN was not available.
I own this truck and have had issues with the exhaust regeneration process for about 6 months. I have taken it to the dealer 3 times and they have done diagnostics and replaced the diesel particulate filter, but the issue continues to happen. They have now told me that the system is not reparable and they don't have support from RAM manufacturer to troubleshoot and repair this issue. They have multiple customers with the same issue with the diesel exhaust system not operating properly, hampering the engine...

performance, damaging the engine and exhaust system, polluting from the exhaust discharge. This is a widely known issue with the 2022 Ram 3500 from other owners, yet RAM refuses to properly address the issue. They advertise their trucks with certain horsepower and output specs, which aren't accurate due to their faulty exhaust systems. Consumers are now completely removing the factoring exhaust systems because they damage the engines and cost thousands of dollars to attempt to repair, which many times never work. This needs to be addressed with RAM and recalls put in place to address the failures with their exhaust systems. My truck has 28,000 miles on it, 3 years old, and is not operable. The dealer has had 3 attempts to repair this and is now turning me away. Please help! Thank you
I got this 2024 vehicle brand new with 15 miles on it in August of 2025 . It is now January of 2026 by check engine light had came on 7 times since November of 2025. I had to shut down work because of this . It came on the 8th time today and I was told by the delearship that they didn't know what to do . My truck is at 43,000 miles and literally a piece of junk.
***1*** The emissions system on this truck (2022 Ram 3500 with 34,435 miles) has been problematic since I acquired it 5 months ago. It continually attempts to regenerate and rid itself of ash/soot buildup. If it does not successfully regenerate, it will go into a state of reduced power, also known as limp mode. The truck is available for inspection and will be at Lithia CDJR in Corpus Christi tomorrow, 07 Jan 2026. ***2*** Today specifically, the truck flashed a message EXHAUST FILTER NEARING FULL SAFELY DRIVE...

AT CONSISTENT SPEED TO CLEAR. I got on the highway to achieve this and avoid lights and stop/go traffic. It typically takes around 25 minutes of consistent driving for it to clear. But today, shortly after I reached highway speeds, the truck entered limp mode, displaying EXHAUST FILTER FULL REDUCED POWER SEE DEALER. This was a very alarming incident that created a bottleneck on the highway and presumably for me to nearly be rear ended as it happened at 5:35pm. I was able to safely make it off of the highway, however this incident has put the lives of all motorists on the road around me today in danger. ***3*** The truck has been inspected numerous times by the dealership. The Diesel Particulate Filter was replaced on 01 October 2025 (this was the first time the truck went into limp mode on me). The frequent regenerations continued after the DPF replacement and a sensor was replaced on 29 October 2025. Regens continue at approximately 1 per week. ***4*** This is a known issue amongst the community of RAM truck owners. It's unfortunate that many do not report it because the safety issue could easily set off a chain reaction, especially if this heavy duty truck were to be towing a heavy load as it capable of doing.

Traction control and ABS work intermittently. Ram sent out this notification for recall concerning stated problems but state there is no fix at this time. They continue to state there is no fix. This is a safety issue and you are not forcing them to repair. They are dragging their feet hoping it goes away. DO SOMETHING!!!!
My pm sensors or particulate matter system malfunction and failed which lead to emissions issues and created my vehicle to drive in limp mode. Limp mode basically slowed downs the vehicle is slow as 5 mph as soon as this light displays at any time while driving on the highway. This put my safety in danger and the public as I transport what dot considers a type hazardous material. The sudden loss of power in the middle of the road has made vehicles around me extremely vulnerable to fatal collisions. I took my vehicle to the dealership where they confirmed this malfunction and problem with my vehicle but no recall has been issued as of yet no warning lamps appeared prior to the failure.

the fuel system. The dealer related the failure to NHTSA Campaign Number: 21V880000 (Fuel System, Diesel), and the vehicle was repaired; however, the contact later became aware that the dealer had replaced the high-pressure fuel pump with the same part. The contact stated that upon taking the vehicle to an independent mechanic to be serviced, the mechanic informed the contact that the high-pressure fuel pump installed on the vehicle was not the recall part, but the same defective part. The mechanic recorded the high-pressure fuel pump and part number, and the vehicle was taken back to the dealer, where it was confirmed that the recall part had not been installed on the vehicle. The manufacturer was notified of the failure and referred the contact to the dealer for assistance. The contact stated that the dealer delayed performing the recall repair free of charge, which required the contact to pay for the replacement of the high-pressure fuel pump with the correct part. The vehicle was repaired. The contact stated that the manufacturer failed to complete the recall repair free of charge. The failure mileage was approximately 38,000.
