SERVICE BRAKES, ELECTRICAL SYSTEM
While driving down the street between 0 and 35 mph, with no load in the truck and no trailer attached, the trailer brake controller quite working completely and a service message appeared. The dealership ended up replacing the trailer brake gain adjustment switch. Had I been towing a trailer at the time, I would have had zero trailer brakes. I've had this message reappear several times since then. I've attached a picture showing both the message on the gauge cluster as well as a scan of the trouble codes at that time.

The 2025 and 2026 dually 3500 Ram trucks with the 12" AAM rear axle are having issues with the rear wheel speed sensors (different sensor for each side). They apparently fail or are not able to properly communicate to the computer. When this happens, the following are disabled: -ABS -Auto Emergency Braking -4x4 -Electronic Stability Control -Cruise Sometimes, the engine won't shut off. The gauge cluster will state it can't detect which position the transmission is in. So, you cannot shift, and you can't shut the truck off, and you can't drive. You are stuck in place with a running engine. Despite Stellantis releasing a new revision of wheel speed sensors (AB revision), they have failed in less than 2,000 miles on my truck. Many, many dually owners are experiencing these failures. I've had this problem occur over half a dozen times. It has been to the dealership to be repaired 3 times so far. After the 2nd time at the dealership, the sensors only last less than 23 miles.

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.

SERVICE BRAKES
Brake system is not functioning as designed. Rear axle braking is not being fully applied and is most noticeable and concerning during heavy haul usage. Vehicle has to be operated carefully and with an alternate braking method utilized to obtain adequate braking. The problem can be and has been reproduced and verified by dealer but not in writing. Dealer is not wanting to fully diagnose and/or commit to finding/acknowledging a fault. Manufacturer has been notified in writing and unresponsive. There are no messages displayed/stored. Disproportionate brake wear between front and rear axle braking is observed.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS, SERVICE BRAKES
Multiple times at random the vehicle will display an alert on the dash that the 4X4 system, anti lock breaks, adaptive breaking as well as forward and rear collision sensors and cruise control are all disabled. This has happened 5 times now. I have taken the vehicle into the dealership and they stated that the rear Wheel Speed Sensors" were bad and replaced them. Since the wheel sensors have been replaced ( less than 200 miles ago) this system has triggered the same alert and conditions 2 more times. This is a very dangerous situation for a vehicle that is made for towing heavy trailers and loads.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The warning lights on the dashboard come on when driving. ABS, VSC, 4WD, automatic emergency braking etc. are all shut down when this happens. The lights may stay on for a few days or turn off at the next restart with only a check engine light remaining on. It has been back to two different the Ram dealer for repairs 4 times for this issue. Starting out on 04/25/2025 at 419 miles, the last time was 12/22/2025 at 3,677 miles. They have replaced several sensors and updated the computer several times, yet the problem still persists. It may be fine for several hundred miles or it may happen several times in one hundred miles. At this point the dealer doesn't seem to know what more to do.

I have had the seal between the transmission and transfer case replaced 3 times due to leaking since new and after each repair within miles of each repair and all prior to the vehicle reaching 50,000 miles. The last time it was repaired at 65,000 miles they decided to replace the transmission with a new transmission - it also leaked between the transmission and transfer case within 1 day and less than 100 miles.

ELECTRICAL SYSTEM, LANE DEPARTURE: BLIND SPOT DETECTION
On January 14, 2026, while starting my 2025 RAM 3500 with approximately 4,000 miles on the vehicle, the digital instrument cluster completely failed to function. After the engine started and the vehicle was running, the dashboard continued to display “Press Brake and Press Button to Start,” as if the vehicle had not started. All gauges and indicators were inoperative, including the speedometer, tachometer, warning lights, and vehicle information displays. Although the vehicle could be driven and exterior turn signals were functioning, there was no indication on the instrument cluster. No speed, engine RPM, or warning alerts were visible to the driver. After driving the vehicle home and allowing it to sit for a period of time, the vehicle was restarted and the instrument cluster returned to normal operation, indicating an intermittent failure. Based on known issues reported with digital instrument cluster failures, this appears to be a potential electrical and/or software-related defect. In addition to the instrument cluster failure, the vehicle has experienced electrical issues related to trailer lighting. When towing a new trailer equipped with LED lights, the running lights would not function when connected to this truck, although the trailer lighting worked properly when connected to other vehicles. The trailer was taken to the manufacturer’s shop for a full inspection, which confirmed the trailer was functioning properly and identified the truck as the source of the issue. On January 12, 2026, during an oil change service, the trailer lighting issue was reported to the dealership. When the technician connected a diagnostic tester to the truck’s trailer wiring connection, portions of the connection began to smoke. The dealership determined there was a defect in the truck’s electrical system and ordered a replacement component. I have video documentation provided by the dealership technician showing the issue at the trailer light connection.

On 12/15/2015 my 2025 RAM 3500 at 30180 miles had a Trailer communication problem with Running lights on trailer not working. It was sent to RAM dealership in Albany, OR. They diagnosed that the Integrated Trailer control module was at fault. It was replaced and passed working operation, On 12/30/25 Ram was connected to Trailer. The Trailer seemed to be fully operational and about 5 miles down the road the Running lights stoped working again. I had trailed tested and no electrical issues were found. Had 7 way trailer pin in Ram tested and showed 12V power but no out for Running lights. Schedule another appointment to go to Wilson Ram in Corvallis, OR. The ran another diagnostic test on it and found it was fully operational and they could not duplicate the issue I was having. As the Ram gets closer to warranty being expired and I use this Ram for business hauling a trailer that it’s a safety issue when Running lights don’t work. I feel that RAM needs to address this problem sooner than later. I will be getting my Ram back on 01/09/2026 and We’ll connect to Trailer once again and see if itheir is no issues this time. I feel a recall should be in place to resolve the problem with a new harness, brake controller and all modules for Trailer Tow system. As a consumer having down time due to having to go back for diagnostics all parts should be replaced if one part of the system has failed. Is it not only a safety issue it can impact business owners who Need their Vehicle to operate their business. Thank you for taking the time and I will submit follow up if these trailer issues continue.

The contact owns a 2026 Ram 3500. The contact stated that while driving at an undisclosed speed, the check engine, 4WD, ABS, park sensors, and several other unknown warning lights illuminated. The vehicle was taken to the dealer, who replaced the speed sensor for the rear wheels; however, the failure persisted, and the transmission failed to recognize that the gear selector was in park(P). Roadside Assistance arrived and unplugged the battery cables to turn off the engine. The vehicle was towed to the dealer and was waiting for engineers to diagnose the vehicle. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 458.

Trucks Navigation and GPS stopped working. Took to dealer for repairs, could not replicate the issue. They brought the truck back to me, and upon starting it the GPS/Navigation is not working. Other than the navigation, more systems work off the gps and needs to be functioning. Have multiple videos of nav not working, and dealer still stated that wasn't enough to determine there was an issue.

Trucks DEF Gauge malfunctioning goes from full, to half, to full, to empty, and then warns about going into limp mode. Filled with DEF and still doing it. Took in for repairs, company said they fixed it, but within 3 miles gauge was doing the same thing. This is a hazard as it will put the truck in limp mode. Known issue with many complaints, needs fixed
