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.

This problem first occurred on a state highway in [XXX] in 2023 and again in 2026 (this incident.) While driving south on XXX, there was an undulation/slight bump in the interstate while in a mild right hand curve. My vehicles brakes engaged without my input and slowed me down from 70mph to 35mph with traffic behind me. My gas accelerator and brake pedal were unresponsive from user input. At no point was my vehicle out of control to trigger such aggressive braking from my ESC, ERM, or ABS. The concern here is that thankfully this was on dry roads and traffic was far enough behind me to avoid a collision. My concern is this happening in winter weather/icy/wet roads, or with significant traffic behind me causing a possible high speed rear-end vehicle accident. There was a safety recall for ESC/ABS a few years ago on my vehicle that I dealt with through the dealer. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

There was a tailgate recall for the tailgate falling down potentially spilling cargo onto the road. The dealership Autonation Dodge in [XXX] tried fixing the recall multiple times but the tailgate kept falling down after they tried to fix it 2 or 3 times. Now they're trying to make me sign a service fee authorization which I don't agree with because either the recall isn't fixed, or there are other issues that can cause the tailgate to fall down which should be included in this recall because they can potentially cause the same dangerous situation which caused the recall.

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

The vehicle has uneven response when turning or driving down the road turn signals do not cancel properly and it has a persistent clicking sound coming from the steering column. My safety is at risk as the steering isnt consistent while driving. Vehicle was inspected but their technicians were unable to find any of the ongoing problems with this vehicle including worn suspension components.this persistent problem with the steering and clicking sound has been ongoing since before I purchased the vehicle back in december with multiple clues after visual examination of a prior accident.
