Ram 2500 Transmission problems by year

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 [[redacted]]. Time - Line PRIOR FACTORY-WARRANTY REPAIR The [redacted] 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...

My 2018 Ram 2500 has a safety recall (C4B/NHTSA 24V - 896) for BRAKES AND TRACTION CONTROL and the remedy for this condition is "NOT CURRENTLY AVAILABLE" ??? I have contacted FCA recall assistance center and 2 different dealers and they all are "SORRY" but say there is nothing they can or will do. One dealer offered to replace the defective part with another defective part if I was willing to pay for it and said that it would probably fail again. How can the US Dept. of Transportation allow a "US auto...

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....

I am reporting a transmission safety problem with my 2016 Ram 2500 Cummins that began shortly after FCA campaign U29 was performed. Before the recall work, the transmission and original solenoid were functioning normally. I had no transmission symptoms, warning lights, or transmission codes. The dealership performed U29 and replaced the transmission solenoid May 4-6, 2026. I picked the truck up May 6 at 149,091 miles. About 79 miles later, the check-engine light came on and transmission problems began. While...

While attempting to pass traffic the truck did not want to shift above or down from 4th gear. This has happened twice now and both times I had to pull over and restart the truck. My safety was put at risk due to lack of propulsion, high rpm of the truck to maintain speed before pulling over. Check engine light came on both times. Although there appears to be a lack of NHTSA reports, I have been sharing this story with others and looking at Facebook groups and it seems the 68RFE transmission is rife with issues and commonly fails while driving, regardless of towing or not.

Transmission Slipping

On August 25, 2026, my 2016 Ram 2500 was parked on private property. The driver states that she placed the automatic transmission in PARK before exiting the vehicle. After she exited, the unoccupied vehicle unexpectedly began rolling and struck a tree, causing vehicle damage. No one was injured. There were no known warning lights or messages indicating a problem before the incident. The cause has not yet been determined and the vehicle has not yet been inspected for this incident. The vehicle is available for...

Transmission can be put into gear without pressing the brake pedal. A child was placed in truck with no key in ignition. The child pulled shift lever and truck started rolling. Driver quickly pressed brake and stopped truck. This truck had the T79/NHTSA 17V-821 recall fix in 2017. The fix did not correct the problem. Filing this report to inform NHTSA that the recall fix did not work. Dealer won't repair as recall had been performed. I bought this truck used and It had this problem when purchased.

Motor completely over heated causing the hose to rupture underneath the intake manifold. Engine is unrepairable. Had to order new engine and a new intake manifold because it melted the current one. Also approximately 2 years ago, I also had to replace the transmission. This truck only has 155,000 miles in it and has had 2 major break downs. WHY? This truck is unsafe.

My family and I tow a 45 foot RV Toy Howler Fifth Wheel with the truck and the ABS and Traction control lights keep coming on. The RAM Dealer (Aventura) has been telling me for over a year that the parts are on back-order. I've tried to trade it in but the trade in offers have been very low since they know there's no repair parts. I'm very concerned about our safety since we take long trips into the mountains and this is constantly going on.

Premature lifter and cam failures on the 6.7 engines. Yes it can be inspected. Yes it was heard and confirmed by multiple dealers and sources. It can be an issue if the engine locks up when driving

ABS, Traction controle and 4 wheel drive system shut down. the truck is sending code- C0031-1D directly related to C4B recall. The dealerships have no fix and offered no support or guidance but did agree that the truck is unsafe to drive as is.

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...

Vehicle has not has cruise control, abs, traction/stability control for over 2 years. No traction control or stability in the winter is horrible. Not being able to control speed when traveling is inconvenient. The warning lamps illuminated and went away for weeks. Then randomly just stayed illuminated. Abs hydraulic pump has failed. The recall has been open for over a year and a half and no parts or remedy to fix it.
