Hi my ram recall for 67a was done and it states that there is a 2 year warranty. It states that it covers the def pump if there is a failure. I purchased the part and sent in a receipt to get a reimbursement for the part. I call and everyone is rude and it goes in a circle and they tell me they can't help. What kind of customer service is this? Why was the recall letter even sent

NHTSA complaint #11757944 — an unverified report by a vehicle owner.
The vehicle has experienced repeated failures of the variable geometry turbocharger (VGT) electronic actuator. The actuator intermittently fails to move the turbo vanes to their commanded position, resulting in fault codes related to turbocharger performance and actuator position. The failed actuator is currently installed on the vehicle and is available for inspection upon request. This failure creates a significant safety concern because the engine can suddenly lose turbocharger performance and enter a reduced-power or "limp mode" condition without warning. During these events, the vehicle experiences a substantial loss of acceleration and power, making it difficult to safely merge onto highways, pass slower traffic, or maintain speed while towing or traveling on grades. This unexpected reduction in power increases the risk of a rear-end collision or other traffic incident, particularly when operating in normal highway traffic. The condition has been reproduced multiple times and confirmed through diagnostic trouble codes. The issue is consistent with a malfunctioning VGT electronic actuator. Numerous other owners of 2013-2018 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins engine have reported similar failures involving the electronic actuator, suggesting this is not an isolated incident. Prior to complete failure, the vehicle displayed intermittent warning symptoms including a Check Engine Light, reduced exhaust brake performance, and occasional turbocharger-related diagnostic trouble codes. The symptoms became progressively more frequent before the actuator ultimately failed to operate reliably. In some cases, cycling the exhaust brake temporarily restored operation, but the problem continued to return and worsened over time. The vehicle has been diagnosed using standard diagnostic equipment, and the fault has been confirmed through the presence of turbocharger actuator-related diagnostic codes.

The vehicle has experienced repeated failures related to the diesel emissions system despite multiple repair attempts. The primary symptom is an illuminated check engine light accompanied by diagnostic trouble code P2459 (Diesel Particulate Filter Regeneration Frequency). The vehicle frequently enters regeneration cycles and continues to exhibit the same symptoms after major emissions system repairs. The emissions system components, including the Diesel Particulate Filter (DPF) and related DEF system components, were previously replaced by an authorized dealer. Following those repairs, the same warning light and fault code returned. The vehicle was subsequently inspected by another authorized dealer, which was unable to identify a definitive cause of the recurring condition. The check engine light was cleared, but it returned less than a week later with the same symptoms. The failure creates a safety concern because the vehicle may enter reduced-power or limp-home operating modes without warning, potentially limiting acceleration and the ability to maintain traffic speed. This is especially concerning when merging onto highways, crossing intersections, towing loads, or operating in heavy traffic. The recurring nature of the failure has reduced confidence in the reliability and safe operation of the vehicle. The condition has been reproduced multiple times and has been documented by authorized service facilities. Warning lamps and fault codes have repeatedly reappeared following repairs. The vehicle and emissions system components remain available for inspection upon request.

Check engine light consistently comes on with codes p0263, p0272, p0266 for contribution balance codes for cylinders 1, 2, 4 & 5. Truck runs rough. Dealership says it’s a 5-8 week process to test and get injectors into replace if that’s the issue. Multiple sources have stated it can be a software update issue and some states still waiting after weeks for fix to be made and paying for a rental car out pocket to have reliable transportation for work and taking care of kids.

Truck def system error derates vehicle speed to 5mph in 85 miles. This is unacceptable as no dealerships are open on weekends or in the middle of nowhere. This EPA rule will get folks killed as folks driving 5mph on freeway towing a big trailer will get run into real quick. Vehicle should NOT cause you to slow to 5mph if a pollution control device has issues. Please investigate.

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.

The contact owns a 2019 Ram 2500. The contact stated that while driving at 50 MPH, there was blue and white smoke coming from the engine compartment. The vehicle was taken back to the residence. The contact saw a cloud of smoke coming from the engine compartment. The contact waited to see where the smoke was coming from and attempted to start however, the vehicle failed to start. The vehicle was then towed to an independent mechanic, where it was diagnosed, and it was determined that the high-pressure fuel pump needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and filed a complaint. The failure mileage was 110,000.

[XXX] I stopped at a stoplight and was sitting with my foot on the brake. With light still red, vehicle went full throttle and began pushing me into the intersection even though my foot had never left the brake. I shifted to neutral and still redlined. Shifted to park and shut off. Restarted and it went back to normal. Luckily it was early morning and I was in a rural community and light traffic. Went home and called Ram dealership and took truck in that day. They kept it several days. Said was showing a code error; but I reiterated it pushed me into the intersection while I continued to pushed the brake to the floor. They did find an inconsistent reading in throttle and replaced the throttle body. I had hoped that corrected the problem and had no issue until [XXX]. [XXX] Left my farm in morning heading for Kansas City for supplies. Pulled onto shoulder of entrance ramp to doublecheck my route before entering the busy highway and rush hour traffic. As I was sitting there with my foot on the brake - same problem. Throttle redlined and (with my foot on the brake) truck began pushing me off the shoulder and down an embankment. Luckily I was an experienced driver and immediately switched it into park and shut it off. Waited a minute then restarted & no issue. Immediately called dealership back and took it in. They tested for a couple days but said it wasn’t showing ‘a code’ so there was really nothing they could do. I said this is huge safety risk to all & both incidents c hold have easily been lethal. They said they sent inquiry to ram but heard nothing. Said I needed to reach out to ram; which I did. I’ve heard nothing other than they assigned a case number & said ‘someone will call’. Every time I use the truck is a huge risk. It’s happened twice in less than 90 days - it will happen again. I need your help, please.

I am reporting ongoing safety concerns with my 2018 RAM 2500 (6.7L Cummins) related to repeated emissions/aftertreatment failures and the lack of timely repair options. These failures directly affect drivability and can create hazardous situations if the vehicle enters derate mode while towing or driving at highway speeds. Over the past year, my truck has suffered multiple emissions-related component failures, including DEF dosing issues, SCR/DPF system faults, repeated warning messages, and the threat of speed-limiting derates. The vehicle is used for normal personal use, is well-maintained, and has not been modified. Despite proper maintenance, the same types of failures continue to recur. A major concern is that local RAM dealers have extremely limited ability to service these issues in a timely manner. Appointments are often weeks out, and when the truck is already in a failure state it is unsafe to continue driving. I have previously reported safety-related defects to NHTSA (ABS/HCU), and those issues later resulted in recalls—so I know that reporting matters. The combination of emissions failures, derate risks, and lack of dealer support creates a situation where the vehicle may suddenly lose power or become unsafe to operate, especially when towing or traveling in rural areas with limited service availability. I am requesting that NHTSA review whether there is a broader pattern of emissions-system failures on RAM heavy-duty trucks with the 6.7 Cummins and whether these failures pose a safety risk due to the forced-derate logic and inability to obtain timely repairs.

My 2022 Ram 2500 6.4L HEMI has a long crank/hard-start issue every morning. It takes 5–6 attempts to start when the vehicle sits overnight. After starting once, it runs normally the rest of the day. I also had issues where the truck struggled to start after refueling. I replaced the gas cap and EVAP purge valve, which improved the refueling issue, but the long-crank cold start continues. I suspect a fuel pump internal check-valve failure causing fuel pressure to bleed down overnight. This is common on these trucks and is a safety concern because the vehicle may fail to start in emergency situations or stall unexpectedly. No check-engine light is present. The issue is repeatable daily.” Faulty fuel pumps in these specific RAM models can suddenly fail while driving. This failure can lead to a complete loss of engine power without warning, increasing the risk of a crash.

My truck will lose all throttle response and brakes harder to stop accompanied by a service electronic brake system, service electronic throttle control, and electronic traction control warning. It only happens intermittently and sometimes will go a few weeks before doing it again. (The date below for incident is latest date it happened)
NHTSA complaint #11691410 — an unverified report by a vehicle owner.
On Sunday, 9/14/25 driving on a 70 MPH interstate highway, pulling a trailer behind the Newly-purchased 2025 truck (only 700 miles on it), the road narrowed down to one lane because of a traffic obstruction and cones. As I slowed down to about 35 mph and then went to speed up again as the traffic eased, the vehicle provided a ping notification sound and the Electronic Vehicular Instrument Cluster (EVIC) display stated something to the effect of "Shift into 'P' to start vehicle". I realized that the vehicle was not responsive as expected, indicating power steering had failed, likely because the engine was off. I'm uncertain whether the steering wheel was locked, which is likely, because at that speed, only a very slight turn of the wheel was needed to move into the closed lane on the straight road. I continued to coast to get the vehicle and trailer over to the right, hugging the cones which were mid-lane in the closed lane, allowing other cars to go around me while I came to a complete stop on the interstate to shift into Park. Once I could get the gearshift into Park, I started the vehicle again, at which point it drove normally. The trailer had been weighed just that morning and both tongue and overall weight were well within the capacity of the vehicle. It was hooked up to the electrical systems of the tow vehicle via the 7-pin connector. I had the EVIC set to show vehicular information - oil pressure, oil temperature, etc. I similarly had information like battery voltage displayed on a widget on the uconnect screen. Everything looked nominal. No error code was logged to my knowledge. I have since seen similar reports from other 2025 RAM owners in NHTSA complaints and on social media. My dealership is unaware of these issues having been reported elsewhere, so they are starting from scratch in finding a diagnosis on a seemingly intermittent issue. That process is ongoing at this time.

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

The check engine light came on and I took the vehicle to the Ram service center. The tech said the turbo actuator caused the light to go on. He reset the computer and said to bring the vehicle back if it comes on again. About 1 month later it reappeared. The Ram service said the turbo charger actuator needed replacing (the complete turbocharger). They said the failure could result in a total loss of power or engine failure. I tow a 10,000 lb trailer and an engine failure on the road could result in an accident or injury due to no power from the engine. The part can be viewed for inspection.

Truck will regen every 100 miles, then Truck will come up with regen message then immediately come up with see dealer full dpf. Truck will start shutting down causing a safety hazard for family in truck. Dealer and ram will claim nothing is wrong with truck. And that we need to continuously pay for dpf manual regen $500 per manual regen (happens once a year). Truck has 32,000 miles and is a 2022. Dealer claims they did the recalls.

Lifters are failing with 31,000 miles. There are thousands of these trucks with less than 30,000 miles on there second or third set of lifters. I took the truck to Allen Samuels Dodge in Aransas pass Texas for a loud rattling kept the truck several days couldn’t figure it out. I recorded a video of the banging inside the engine they kept the truck 5 days or so gave me a letter saying it’s under investigation and I should call Ram about the lifters. Called Ram they said call the dealer or take it to another dealer. Service guy was like yeah the lifters are failing left n right and locking up the engine. The grid heater bolt is burning off and falling into the number 6 piston on these trucks locking up the engine. I have numerous screen shots from several Ram 2500 groups where people are getting new engines just for it to fail in 3000 miles. I’ve got a 70k truck I’m afraid to drive worried it’s going to rattle apart and lock up the engine while driving down the highway. I can screen shot way more complaints. There’s even someone who started a data base in online forums to record complaints. The transmissions are failing in these 2018-2024 Ram 2500 6.7 Cummins and the gas version to. It’s ridiculous
