2024 Ram 3500 Powertrain & Transmission Problems

On 01/21/2026 there was a warning light that came on stating accelerator control sensor, the next morning the truck started stalling, and continued stalling multiple times. I attempted to get the vehicle to the service center. It then stalled 2 more times, the service center told me they couldn’t look at the truck until the next day, the vehicle then stalled on me again that evening, they kept the truck until Friday evening, and told me they couldn’t duplicate the issue. They knew it had happened, but they couldn’t find the cause without replacing a bunch of parts until they found the correct issue. I took the vehicle home, started it the next morning and the maintenance required issue again returned, I took it back to the service center, they checked the codes, and told me it shows the 3rd taillight is staying on which indicates usually a fuel issue. They then sent me a quote stating a bunch of things that’s already been done to the vehicle outside of their service center, as well as the part they told me was where they had started to diagnose the issue and it didn’t work, all of which are not covered under the current warranties of the vehicle and basically the way I understood it that I would have to keep buying parts and replacing things out of pocket until the drivetrain issues were resolved.

RAM 3500 truck was purchased in Ventura, CA and has experienced multiple electrical and drivetrain failures beginning shortly after purchase. In January 2025 while traveling in Oregon, the infotainment system repeatedly blacked out and the cruise control button stopped functioning. A dealership replaced the cruise control button, restoring cruise control, but the infotainment problem remained. When the vehicle was returned after the repair, a new defect appeared: the horn button no longer worked. Loss of the horn creates a safety risk because the driver cannot warn other vehicles or pedestrians. Around 20,000 miles during a routine service visit at the selling dealership in Ventura, we reported a driveline vibration. The dealership and the upfitter inspected the vehicle and observed tire cupping. They checked the tires for premature wear and recommended overinflating tires as a remedy. The vibration continued and worsened, the infotainment failures persisted. In October 2025 while driving in Wyoming, the vehicle experienced a major drivetrain failure involving the front differential and axle assembly and required towing. The truck was first towed to the Yeti dealership in Afton, Wyoming, which closed shortly after the vehicle arrived. The truck then had to be towed again to Yeti dealership in Jackson Hole. There, technicians diagnosed front differential and axle assembly as the primary failure and also observed premature wear on aftermarket shocks installed by the upfitter. Technicians indicated the differential assembly was not readily available and would require special order. The vehicle was later transferred to another dealership in Dodge City for repair, but the differential components were not immediately inspected or ordered, causing additional delay. The vehicle remains out of service awaiting drivetrain repair. Safety concerns include horn failure, repeated electrical malfunctions, and drivetrain failure while driving.

We bought our 2024 3500 Dodge RAM in Florida in late March. Last weekend the truck started to feel like it was jerking while we were pulling our 5th wheel. On Monday we schedule an appointment in Brockton Massachusetts at a dealership. We were told there need to be a system update and that it was all set. On Wednesday we started our 3 hour drive to Maine when suddenly while we were on the highway the truck began to overheat and revving loud only going 35mph. We pulled over into a parking lot and called RAM roadside assistance. We were told to let the truck cool down and try again. After being in a parking lot with our 4 kids and 2 dogs in 100 degree weather for 6 hours we attempted to start the truck. However every time we put it in drive the truck shut off. At this time we had to get it towed for $300, today the local RAM autoshop is saying they looked at the truck and transmission is gone. They are also saying they will not be able to look at the truck for a month. We travel full-time in our RV and now are stranded with our RV and no way to pull it anywhere.

Vehicle displayed warnings: Service Antilock Brakes Service Electronic Stability Control Service Trailer Brake System The truck has only 4,650 miles on it. When this happens, the above systems do not work along with the 4 wheel drive system. When towing a heavy trailer, the loss of trailer brakes can easily cause an accident due to jackknifing of the trailer and greatly increased stopping distance. Loosing 4 wheel drive in snow or mud can cause an accident or getting stuck.

Excessive Diesel Exhaust Regeneration. Vehicle in in regeneration about 72% of the time. Check engine light comes on about every 2 weeks with code P2459. The P2459 code indicates an issue with the diesel particulate filter (DPF) regeneration frequency in diesel vehicles. This code is triggered when the powertrain control module (PCM) detects that the DPF regeneration process has not occurred as expected. Have to take to dealership for a manual regeneration and to clear the code. Dealership says this is a known issue for Ram Diesel engines from 2018-2024. Dealership says Ram has yet to address the issue even though its been 7 years since the issue started in the 2018 model year. Been dealing with this for a year now.

My new truck lost power on highway. Parking position didn't hold the car from movement. My car didn't drive forward and rear. Dealership said that its transfer case issue.
