Dealer has not responded to written requests to perform federally mandated Recall Y78 on my 2019 Ram 2500 (VIN: [XXX] ). I have been told recall work may be declined due to an insurance claim or vehicle history references. No manufacturer directive has been provided. I am requesting the federal safety agency review of recall nonperformance.

Following completion of the Y78 (high-pressure fuel pump) and XQ1 (emissions) recall repairs in April 2024, our 2019 Ram 2500 immediately began experiencing misfires, fuel system issues, and ongoing performance problems. These symptoms have persisted for over a year and have never been resolved despite repeated service visits and escalations. The vehicle suffered multiple HPFP failures, including one that caused fuel to leak into the crankcase, resulting in approximately 19 quarts of fuel-contaminated engine oil. Despite technical service bulletins calling for specific system flushes and tests post-repair, the original dealership did not follow these protocols or provide documentation confirming that the required inspections (fuel pressure, contamination checks, EGR/DPF/DEF system functionality) were ever completed. A new dealership confirmed the presence of metal debris after the fuel filter, suggesting the system was still contaminated even after the prior recall-related flush and HPFP replacements. They also found non-functional emissions components covered under XQ1, including a failed DPF urea pump and a faulty NASA pressure sensor. These failures were not documented or addressed by the original repair facility. Despite these clear safety risks, the recall is considered “completed,” leaving us with a vehicle that is still experiencing symptoms consistent with the original recall condition. The failure to properly inspect, document, and address these defects has placed our safety at risk and caused prolonged loss of vehicle use. The issue, confirmed by a 2nd authorized dealership, identified fuel contamination & failure in multiple components of the emissions systems. The check engine light appeared prior to the initial failure and has recurred each time the vehicle was returned after service. Given the continued presence of recall-related symptoms and the lack of proper inspection & documentation, this unresolved recall should be reopened and investigated

I bought this vehicle used at around 105,000 miles. I have since spent almost $22,000 on repairing of the diesel exhaust system.. my vehicle is actually in the shop now it’s been in the shop since middle of October on and off as they cannot effectively diagnose the problem. Actually they can diagnose the problem. They just can’t fix the problem. I have all my receipts, but they are in the truck currently and the truck is currently at the dealership here in Imlay city Michigan. This issue has been going on for the last two years at around a total cost to me of $20,000.

The truck was initially brought in on April 10, 2024, for a continuous regeneration issue with the DPF filter, showing codes P242F and P1451. The dealership diagnosed it as requiring a new EGR valve and possibly a DPF filter assembly, under the VB6 emissions recall and extended warranty (XQ1). After replacing the EGR valve, the Y-78 HPFP safety recall was completed. Upon completion, the technician noted multiple fuel-related DTCs, lack of power, and metal debris at the fuel control actuator caused by a failed CP4 pump. At this time, the dealership was unaware of the XQ1 warranty, so instead of replacing the DPF filter, they force regenerated it. Upon picking up the truck, the check engine light came on (April 26, 2024). After reporting it, the dealership stated the DPF filter needed replacement, and on May 26, 2024, it was replaced under XQ1. However, after picking up the truck again, the check engine light came back on, and diagnostics revealed misfires across all six cylinders (codes P0300–P0306) and abnormally high fuel pressure at the wire harness—issues that weren't present before the EGR valve or HPFP recall repairs. The truck has since remained at the dealership, with multiple unsuccessful attempts to fix the issue by replacing the fuel lifter, wire harness, fuel filter, and a second Y-78 recall replacement due to "faulty parts" from the first attempt. The dealership charged a diagnostic fee and suggested replacing rocker arms and push rods, but this did not resolve the problem. The dealership has since recommended replacing the PCM module but then retracted the recommendation and is now requesting a new diagnostic fee to tear down the engine, remove cylinder heads, and inspect for debris, as the misfires and high fuel pressure have persisted since April 26. The safety concern is that the truck behaves as though it is starving for fuel when the engine light reappears, with stored codes showing misfires and high fuel pressure, related to Y-78.

On June 26, 2024 during a long road trip, the vehicle lost power repeatedly in the middle of an area with no road service. It put my safety and that of my passenger at risk on the highway as losing power suddenly causes danger in fast-moving traffic causing the risk of potential collisions with other vehicles. There was no warning lamp indicating the failure would occur. To this date, the dealer has not fixed the issue. After approximately three weeks, I picked up the vehicle after it as allegedly repaired (at that time the dealer stated it was an electrical issue). The vehicle failed again not more than one-half mile from the Omak Dodge service center placing my safety at risk yet again. I managed to get the vehicle back to the service center at which time, the dealer stated after consultation with RAM technical support, that the issue was a failure in the fuel system. The dealer claims that the problem was the failure of a fuel injector/pump that caused particulate matter to contaminate the entire fuel system. Being that it was allegedly a power train failure, it was to have been covered under the power train warranty. After approximately three months of delay, the dealer stated the truck was repaired. On arriving at the dealer to pick up the truck, the dealer stated it wasn't repaired and had an exhaust issue. The truck remains at the dealer to this date, October 25, 2024. The dealer states that the exhaust issue is yet another issue with the truck that is covered under a warranty voluntarily extended to 10 years by RAM.

I had recall work done on my truck on 3/2023- it is not listed on your website that anything has been fixed on my truck. My truck quit working 5/2023 and has been at my personal shop since then. They ended up doing the same work as the recall that was performed on 3/2023 and is not working still. I looked up on the website and our vehicle is showing no recalls were done on this truck. The dealership is having me jump through hoops to have them take the vehicle back to try to fix the recall that my personal dealership said was wrong with the vehicle.
