While towing a trailer on an up hill grade my Ram 1500 suddenly stopped pulling and began rolling back. It stopped using the breaks but would not shift out of drive. Luckily the Park break was still functional and held the vehicle in place until roadside assistance arrived.

Transmission issues are a known problem in the 2021 Ram 1500 and have been for a while, with no recalls. Slipping of gear. Delay or jerking into reverse. Putting it in reverse and it telling me to put it into park or it auto-correcting itself into park. While driving twice and going from complete stop after the auto correcting went to pull off & the vehicle did not go into gear the RPM was raised and the truck moved forward but would not go into gear. The smell of transmission fluid and possible coolant seem to be in truck through vent. The Malfunction Indicator light came on. Had a Shop check code said it showed Valve Body. All these are known issues with the transmission and should be recalled as this is very dangerous for driving as it could stop in road, loose power going up hill on interstate and if there are leaks it could cause a fire. There should have been recalls and investigations. Manufacture knows these issues are and have been happening but does not want to spend the money to fix problems. Ignores and hopes warranty will be gone before it happens so it will be on the owner. That is what they did with me.

My 2026 RAM 1500, with approximately 3,900 miles, experienced an unexpected engine shutdown on October 13, 2026. After entering the vehicle, fastening my seatbelt, pressing the brake, and starting the engine, the engine ran for approximately one second. When I attempted to shift into Reverse, the engine shut off and the transmission automatically went into Park. The dashboard and electronics remained powered, but the vehicle would not shift into another gear or respond to the start button. After completely shutting down the vehicle’s electronics, I was able to restart the engine, and the truck operated normally. The vehicle has also experienced intermittent infotainment failures, including CarPlay freezing, the radio remaining on after shutdown, and navigation updates failing. These issues began around mid-September 2026. I am concerned about the possibility of the engine shutting down unexpectedly again, potentially while driving.

ABS control module “A” has failed internally. Vehicle went into limp mode and is inoperable due to this issue. I’ve eliminated other possibilities as to the cause and have narrowed it down to the ABS control module. ABS light, traction control, brake, electronic throttle control, and service shifter lights are all activated and activated at the time that the issue began.

While driving a 2023 Ram 1500 EcoDiesel (37,000 miles) at highway speeds while towing a load on an incline grade, the vehicle experienced a sudden, uncommanded drop into an aggressive "Limp Mode." The dashboard displayed a "Service Electronic Throttle" warning, and engine power was immediately and severely restricted. While I was able to safely move the vehicle over to the shoulder, the truck completely lost the power required to maintain highway speed, increase speed, or clear the incline grade. A diagnostic scan revealed code P00AF (Turbocharger Boost Control Module Performance). After sitting for several minutes the limp mode cleared and was able to drive off as normal, however the limp mode condition returned in only a few miles. Due to the hazard of driving significantly below the highway speed limit while towing, the code had to be manually cleared to temporarily restore throttle response and safely complete the drive. The vehicle is experiencing an intermittent electronic or mechanical breakdown within the boost control system that causes an unpredictable risk of sudden power loss during highway operation. This condition has presented on 3 separate occurrences throughout the Summer of 2026. Each time manually clearing the code makes the truck operate normally until the next intermittent occurrence.
