The contact owns a 2017 Ram 2500. The contact received notification of the federal safety agency Campaign Number: 24V896000 (Service Brakes, Hydraulic); however, the part to do the recall repair was not available. The contact stated that while driving at various speeds, the ABS and check engine warning lights illuminated. The vehicle was initially taken to the dealer to be diagnosed. The diagnostic test determined that there was a failure with the ECM. The ECM was replaced; however, soon after the repair, the warning lights returned with the vehicle going into LIMP Mode. The vehicle was taken back to dealer, where the vehicle remained for months while attempting to determine the cause of the failure. The contact was then informed that the transmission needed to be replaced. The contact was provided an estimate for the repair, and the vehicle was towed to an independent mechanic, where a diagnostic test indicated a failure with the hydraulic control unit (HCU). Several repairs were performed, but failed to correct the failure. The mechanic replaced the transmission twice; however, the failure returned after each repair. The manufacturer was notified about the failure, and the contact was provided with two case numbers. The vehicle was not repaired and remained with the independent mechanic. The failure mileage was 82,792.

My 2017 Ram 2500, 6.4L Hemi experiences warning lights which I'm told is caused by intermittent PCM failure. I'm told this can cause the truck to stall while in motion, refuse to start, or enter "limp mode". This amounts to a possible unsafe condition that can put myself and passengers at risk of property damage, bodily injury or worse. I brought the truck to Priority Automotive of Westerly, LLC on March 9, 2026 for diagnosis. Their diagnosis (attached) recommended replacing the PCM to correct (possibly), "...intermittent internal short(s)". Cost of the repair is $2,012.42. Subsequently, I contacted customer care at Stellantis (866‑726‑4636) and was given Case #[XXX]. I was told to make an appointment at the aforementioned dealership and call them the day before the appointment, so they could send a representative to the dealership for examination. I did exactly that to no avail. No one from Stellantis even contacted the dealership on the appointment date. I called them to find out what happened, only to find out (from a supervisor) that they are not offering assistance in the matter. Additionally, the truck is currently under recall #C4B/the federal safety agency 24V‑896 (PCM related) and, to-date, I'm told the part is still not available after more than a year since the recall. I've owned Dodge Rams for over 27 years and find the situation unsafe and totally unacceptable. I'm also aware that many other owners of the 2017 Ram 2500 6.4L experience PCM/ECM issues, causing no-start conditions or stalling, and have reported them alongside braking system complaints.

The truck went into “limp mode” while driving about 60mph which jerked really hard and almost made me lose control of the truck. I took it to the dealer which cost me $2,000 for a transmission solenoid.
