I am writing to formally follow up regarding complaint/case number 97989810 through Dodge and to request that this matter be elevated for a complete technical review concerning my 2021 Ram 2500 6.7L Cummins, VIN [XXX]. Time - Line PRIOR FACTORY-WARRANTY REPAIR The XXX factory-warranty repair is an important part of this vehicle's mechanical history. That repair involved the timing-cover/timing-gear-case area and front crankshaft seal. As part of that repair, the harmonic balancer/vibration damper was removed and reinstalled. Approximately 26,000 miles later, the vehicle experienced a failure involving the vibration damper and its associated mounting bolts. +++ Vehicle receipt will be attached XXX took vehicle Naples Dodge after large thump and vehicle would not move Per dealership - Finding - Advise it was an after market tune that caused harmonic balancer got loose and sheered the bolts Ongoing the dealership provided video and several reports that it was an after market tune no coralation between the 2024 service and findings today Findings: Cummins Service Technician XXX technician report In XXX Cummins filed a safety recall with the federal safety agency (Campaign ID 24V‑192) concerning certain engines equipped with vibration dampers are the critical details of the recall:The Issue: The front vibration damper capscrews (mounting bolts) were not torqued to specification during assembly. If left unaddressed, the capscrews could fracture or loosen, potentially causing the vibration damper to separate from the engine. This creates a high risk of personal injury, mechanical failure, or property damage.(Note: If you are looking for Dodge Ram trucks, Cummins also issued a Technical Service Bulletin—TSB210097—addressing fluid degradation and capscrew fractures on viscous vibration dampers for B6.7 engines, though it was handled as a service bulletin rather than a sweeping automotive safety recall).

There is a known issue with the Ram Power Wagon locking differential system where the electronic locking differential wiring harness will fault one of three ways. The first being that the wiring harness is two short so when the rear axle articulates there isn't enough slack therefore causing the plug in the diff housing to fail. The second is that sensor inside the housing faults due to gear oil build up on the sensor. Finally the third if the locker wiring inside the housing wears out causes the locker to fault. Any of these three issues causes a "Service Axle Locker System" and prevents the front and rear lockers to be used indefinitely. This can cause the truck to become stuck during off pavement driving.

The 68RFE automatic transmission in this 2021 Ram 2500 6.7L Cummins fails to engage reverse when the transmission reaches operating temperature. When the gear selector is placed in reverse and the accelerator is applied, the engine revs but the truck does not move. The defect is intermittent and temperature-dependent, which means it cannot be predicted or avoided by the driver. The vehicle is used to tow an enclosed cargo trailer weighing approximately 7,000 pounds.The safety risk: inability to engage reverse on demand creates a hazard in any situation requiring reverse motion, including backing away from a stopped vehicle, reversing out of a fuel station, backing a loaded trailer at a campground or boat ramp, or executing an evasive reverse maneuver. With a trailer attached, loss of reverse function can leave the truck and trailer stranded in active traffic lanes or at intersections.The defect was first reported to a dealer in August 2023 with diagnostic trouble code P2701 stored (Friction Element B implausible pressure, internal transmission fault). The code was logged but not addressed at that visit. Over the following 32 months the same defect was reported to the same dealer four additional times. On the fourth visit the dealer replaced the complete transmission and torque converter under warranty and certified the repair complete after a documented 77 mile dealer test drive. The same defect returned approximately 4 customer miles after the truck was returned to me. The truck is currently at the dealer for the fifth repair attempt, with the dealer's own write-up confirming that the vehicle will not move while in reverse at operating temperature.The defect has been confirmed by the dealer service department through their own diagnostic process, has been documented across five repair orders, and has resulted in a complete factory transmission and torque converter replacement that failed to resolve the issue.Warning indicators: a P2701 diagnostic trouble code was s

I am reporting a serious safety issue with my 2021 Ram 2500 (VIN: [XXX] ). The truck has experienced three separate transmission failures within a few months. Each time the transmission was replaced, the vehicle failed again shortly afterward. At one point, the dealership returned the truck to me without transmission fluid, causing additional internal damage and creating an extreme safety risk. I have also had steering issues since the truck was new, which continue today despite multiple service attempts. Shortly after purchase, the truck developed severe mold and water intrusion after the roof stop lamp was removed or stolen while the vehicle was at the dealership for service. This caused water to leak into the interior and contaminate the carpet. The dealership replaced the carpet but the issues continued. The repeated transmission failures, steering defects, and water intrusion have made this truck unsafe to drive. The vehicle has lost significant value, and the dealership and manufacturer have been unable to correct the defects after numerous attempts. I am requesting an the federal safety agency investigation into these issues, including: •Repeated transmission failures •Ongoing steering defects •Improper repair practices •Water intrusion and mold exposure •Dealer negligence These failures represent a serious safety hazard to both myself and others on the road.

I have attempted to get 2 recalls that require parts completed at my local Ram dealer who has called me both times saying that the parts were in, and they were ready to schedule the appointment to complete the recalls. The first appointment was on September 25th, 2023, and when the vehicle was checked in, I was informed they had no parts to complete 2 of the 3 recalls that existed at that time. They completed the recall that required no parts and said I was put back on the list for the ones that required parts with no answer of why the parts were not available (I had been put on the list for the parts in June). I received another call in the middle of November that the parts were in and scheduled an appointment for the 18th of December. I called the dealer today to confirm (11th of December) the parts were in fact available and was told they were not because I did not answer my phone, to of which I replied I already had an appointment scheduled for those parts. The only remedy the dealer offered was to be placed back on the parts list for the third time. I then called FCA's recall center twice and was told both times my only remedy was to get back on the parts list again for parts they said was readily available or try another dealer. The grid heater relay has already had 2 previous recalls completed and I have been trying to not park near structures following the recall directions for a long time now until this gets resolved.
