I haven't had an accident yet, but the car beeps at me constantly. It's very distracting. Abs / traction control lights constantly going on and off. Also had issues with transmission, gears shifting hard, 4wd bushings in transfer case, etc. I have asked for an update on recalls many times. No part available. It's been almost 2 years. Doesn't seem that they plan to address the issue.

Gas cap light come on took to a mechanic they dropped gas tank and found the rollover valve is cracked and not working Ram does not want to take any responsibility for poor engineering for making it
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
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.
Vehicle caught fire while engine was running, vehicle idling. Vehicle is a total loss. Prior NHTSA complaints regarding these vehicles causing fire from electrical components under the hood. Unknown if fire was due to electrical or leaking fuel issues under the hood. Major safety risk to occupants, especially children in car seats. Fire became out of control and burned the interior of the vehicle to bare metal. There were no injuries in this incident. This report being submitted by Law Enforcement on owners behalf. Full report from Law Enforcement included in this complaint.
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.
Dealer has not responded to written requests to perform federally mandated Recall Y78 on my 2019 Ram 2500 (VIN: [[redacted]] ). I have been told recall work may be declined due to an insurance claim or vehicle history references. No manufacturer directive has been provided.

My passenger headlights keeps going in and out. The wiring harness has been replaced twice and it still does it. My check engine light keeps coming on for the evap system even though its been replaced.
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.
Our 2012 RAM 2500 truck with 135k miles, had it's fuel tank fail. The dealership in Oak Ridge, TN tested the vehicle and found that the gas tank tubes were broken causing us to not be able to fill the tank. The dealership recommended "NEED TO REPLACE GAS TANK". Mopar aka Stellantis does not make the fuel tank anymore, the "replacement" fuel tank does not work (completely wrong configuration), there is not an aftermarket tank. We have a Million Mile bumper to bumper warranty with MOPAR. "Customer Care" does not care.
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)
Subject: Fuel System Failure Resulting in Engine Damage - 2020 RAM 2500 Pickup VIN: [[redacted]] 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: [[redacted]] ) 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 #[[redacted]]. 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), 5 U.S.C. 552(B)(6)
