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 driving, including on the interstate, the truck would suddenly jerk, the RPMs would rise quickly, and the truck would lose speed. On several occasions, traffic behind me had to react quickly to avoid hitting me. The dealership told me the solenoid installed during the U29 repair was defective and replaced it with another solenoid. The same problems continued. The truck later developed code P0871, became undriveable, and was towed back June 1. The original transmission ultimately failed. The dealership then installed a Mopar remanufactured transmission. I picked it up June 13. Within roughly 600 miles, it developed substantially identical symptoms and failure patterns, including P0870 and P0871, limp mode, and another major transmission failure. It was towed back June 24. The dealership later found the overdrive clutch had disintegrated and metal was present in the transmission fluid. The failed remanufactured transmission is now being handled under its Mopar warranty, and the dealership is looking to install a third transmission without identifying a clear reason for the repeated failures. I am concerned the same problem could happen again and believe the U29 repair, replacement parts, or another related transmission problem should be investigated.

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 the federal safety agency 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.

The electronic throttle control light and check engine light are on. I took it to a mechanic and had the accelerator pedal replaced. The lights remained on and the truck remains in "limp mode" and will not go over 59mph. The mechanic stated that this is due to the unresolved recall problems with the traction control and anti lock braking system, and the HCU needing replaced. These components and labor are over 2-3 thousand dollars! I have called the federal safety agency and the manufacturer with questions and asked for a timeframe for a fix and have received nothing.

My 2018 dodge ram has an open recall since December 2024. There are no parts/no fix. My truck has been dinging and pinging with the break light/traction light/engine light/ABS light since 6 months after I got it. ALL of these things are related to the open recall. VIN [XXX]. Manufacturer Recall Number C4B, the federal safety agency Recall Number24V-896. "The loss of ABS/ESC/Traction control may cause a vehicle crash without prior warning." On Sunday the 19th it stalled along with the warning lights. I took my truck to the dealer and paid $198 in Feb 2023 and they told me nothing was wrong with it. This issues would happen every so often now it's happening frequently almost daily. Customer care refuses to help. They told me to take my truck to a dealer to get it diagnosed and then send the paperwork to them and maybe they'd cover the rental until the part comes in. So now I am paying another $255 for Another diagnostics. It's sitting at Dodge in Glendora, CA right now for 2 days waiting for a call back. I was also told if it's approved, I have to pay for the rental out of pocket. For an eternity? I am not sure why I am jumping through hoops for a safety recall. It' the only car I have to commute and drive my kids in. Once again, a safety recall. This is really absurd. I begged for a manager or someone higher to call me and Ram care refused. Said they'd send my case to rentals. What if my breaks go out, what if I get in a car accident. It feels really unreasonable they won't take responsibility for this ongoing open recall that is a safety issue.
