2025 RAM 3500 Problems & Complaints

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.

Brand new truck (497 miles) while driving on freeway at 70 mph, truck kicked out of cruise control and threw traction control, adaptive cruise control, 4wd, check engine, and anti lock brakes disabled fault lights and codes. The vehicle will disable all these safety features for 30-50 miles, and then the faults will randomly disappear except for the check engine light. This has happened 10-12 times. This truck has had 4-5 “ram cares” case numbers, has been at the dealership for over a month combined. The faulty part supposedly is a right rear wheel speed sensor on the 12” dually axles. There is hundreds if not thousands of these trucks affected. Stellantis/ram says the sensor is has been updated, but is currently not built or for sale., there is a national backorder. We are being told to drive these trucks while ram comes up with a fix. These speed sensors affect systems that have been federally mandated since September of 2012 (anti lock brakes). They are putting customers and other drivers on the road in danger with the intermittent failure of the brakes and traction control in wet conditions.

The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The vehicle was not repaired. The contact had not experienced a failure.

The contact owns a 2025 Ram 3500. The contact received notification of NHTSA Campaign Number: 26V059000 (EXTERIOR LIGHTING, ELECTRICAL SYSTEM). The contact noticed the failure on the drive back after the vehicle was purchased. The contact stated that on a separate occasion, while driving at an undisclosed speed, the brake lights and turn signals failed to function as intended. The contact lived in a rural area and stated that at night it is dark, and the brake lights nor the turn signals were operable. The contact felt that the vehicle was unsafe to drive. The local dealer was contacted, and the contact was informed that the parts for the recall repair were available. However, the parts were allocated to unsold vehicles first, and there was no estimated time for the recall part to be available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue and confirmed with the dealer about the part not being available. The contact was informed that the recall part was blocked from manual ordering. The failure mileage was approximately 500.

When I was going to torn off the truck won’t stop the engine, dash said not in parking and the PRND light start flashing I had to remove a relay to shut down the truck and disconnect bought batteries half and hour later reconnect everything and truck work but with many lights on in dash board From what I investigated it’s a common problem with no solution at this time Dealer said it’s a rear speed sensor What should I do

There is a recall for the trailer brake control and trailer wiring for light. I bought the truck to tow my 5th wheel trailer and have travel plans starting in march of this year.. ram has put a stop sale on 450k trucks because of this recall. The dealers are fixing the unsold trucks on the lot before they fix customer vehicles that have already been purchased. All the dealerships in Arizona are telling me it could be 3-6 months before my truck is fixed.. so I can’t safely tow a trailer or go on my trips. So basically I have a 1 ton truck that is useless to tow a trailer

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.

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.

2025 ram 3500 dual rear wheel truck has intermittent anti lock brake failure . As well as traction control, forward collision warning/assist, lane departure, high beam headlights, and other safety systems. The dealership has tried to fix these issues 8 or more times, with no success. It is illegal for Ram and Stellantis to put customers back into vehicles with anti lock brake failures. In wet/slick/or hard braking situations, loss of anti lock brakes is dangerous to my family as well as other drivers on the roads. And that danger increases when towing a large trailer when the failure happens. The dealership and Stellantis/Ram know of these problems with 2025-26 dual rear wheel Ram pickups.

I received notification of a safety recall on my 2025 Ram 3500 (NHTSA Recall Number26V-059) which affects the trailer lights and braking system. I contacted my dealership to schedule the repair and was told that it would be about 6+ months before they could get to me. The dealership has 30+ trucks on their lot, and the manufacturer is only allowing them to order 1 replacement part per week, so they aren't fixing sold trucks until those 30+ unsold trucks are fixed, which will take 30+ weeks. I'm submitting this online complaint because I tow a large trailer regularly and I don't feel that 6+ months is an appropriate time period for fixing a recall and I don't think that fixing unsold trucks should take priority over fixing trucks that are actively being driven every day.

The contact owns a 2025 Ram 3500. The contact stated that while driving approximately 60 MPH, several unknown warning lights illuminated, and the vehicle stalled. The vehicle was towed to a dealer where it was diagnosed, and determined that several repairs were needed, and there was an issue with the battery. The dealer replaced two batteries, but the failure persisted. The vehicle was taken back to the same dealer, but the cause of the failure was not duplicated. On another occasion, while driving approximately 50 MPH and hauling a trailer, there were several unknown warning lights illuminated, and the contact heard a loud banging coming from the engine compartment before the vehicle stalled. The vehicle was towed to a different dealer, where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 9,000.

Contacted local Dodge dealer for repair of the below known part issue. They stated they are only receiving 1 unit/week to be able to replace and the repair could be weeks out. I use my truck for towing frequently and am not comfortable doing so with the upcoming recall known. Manufacturer Recall Number03D NHTSA Recall Number26V-059 Recall StatusRecall Incomplete

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.

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.

Bad wheel speed sensor which disables ABS, cruise control, and all the ADAS systems. Vehicle has been to dealer 5 times for this in less than 8 months. Stellantis takes over a month to replace the part. Vehicle also will not shut off and/or be able to move while this happens.

The contact owns a 2025 Ram 3500. The contact stated that the front passenger's side, rear passenger's side, and driver's side seat belt reminder (SBR) system was inoperable. There was no warning light illuminated. The vehicle was taken to the dealer, where a third-party engineer diagnosed the vehicle and determined that the vehicle was only designed with a front driver's seat belt reminder (SBR). The manufacturer later informed the contact that Ram engineers had confirmed that the vehicle was operating as designed. The vehicle was not repaired. The failure mileage was approximately 18.

Digital Rearview Mirror has changed from being clear to being cloudy and bright (white) making it impossible to see.

I have experienced two major issues. The dash cluster went blank. Not able to see any of the gauges. Vehicle ran, drove. Turned the truck on and off. Opening & closing the door to power off the truck. 15/- minutes for the dash to return to normal. Supposedly an update to the program is pending. Second and major issue; while backing up, the truck came to a stop by itself, blocking an intersection. I was not able to place the truck in any gear. Warning light notified me that the truck was not in park. We were unable to push the truck out of the intersection. The dealer says when the "Wheel Speed Sensor" failed the truck is programed to be immobilized. I have recently returned from a trip to the Rockies pulling a 35 foot 5th wheel RV. I have traveled several mountain roads. One 12 mile stretch with a 8% grade. Had the wheel sensors failed on any of these roads the chance of and accident were great. Potentially deadly. This is a known issue. Ram has decided to use the newly redesigned parts for production of new vehicles. No parts are available or estimated ship date. My truck has been towed to Capitol Ram of Garner, NC and will sit until Ram decides to provide parts. Part numbers: 68646345AA Left & 68646344AA Right

Ton of warning lights can on like abs, traction control and some other sensors. When put in Drive the D flashed and try k would not move. Put back in park would not recognize it was in park and would not shut off. The only way to shut off the truck with disconnect both batteries and pull the fuse for the fuel pump.
