I have a 2025 ram 2500 diesel, and I use it to tow, as I am a farmer, and have a farm. I pull stock trailers, my tractor, and other trailers associated with my farm. I took my truck in for the trailer tow module recall to be done over 4 months ago, and they said they had to order the part and would call once it came in. It has now been over 4 months, I have called the dealer to follow up, and keep getting the same answer. The part hasn't arrived yet, and they will call me when it comes in. Every time I hook up a trailer it disables my trailer brakes, throws the AEB light on, and I am afraid, that in the instance I have to stop abruptly, that I may crash, and or hurt or even Kill someone due to these issues. I'm at a loss, they are worried about doing the trucks on the lot before they take care of the ones on the road per Jeremy at the Crain Ram dealership in Hot Springs, AR, which I don't feel is right to do. They got my money, now I have to deal with the issue, and potentially worse, until they get their unsold trucks done on the lot. Any help would be GREATLY appreciated!

I attempted to use the factory-equipped 110V power outlet located in the bed/rear area of my truck to power a laptop computer. After plugging in the device, I discovered that the outlet was not supplying any electrical power. The vehicle is equipped with a cargo light/power outlet activation button located beneath the steering wheel. Even with the button engaged and activated as intended, the outlet remained inoperative and provided no power output. Due to concerns regarding a possible electrical system defect, I brought the vehicle to the dealership for diagnosis and repair. After inspection, the dealership advised that a wiring-related issue was found and repaired in order to restore functionality to the outlet system. I am concerned that a wiring defect occurred on a brand-new vehicle and believe this reflects poor workmanship and inadequate quality control during manufacturing. In addition to this issue, my truck has experienced several other mechanical and electrical problems within only a few months of ownership. Because this issue involved the vehicle’s electrical system and required dealer repair shortly after purchase, I am requesting that NHTSA document and review this complaint for potential manufacturing or electrical system defects affecting this vehicle platform.

I parked in a lot for about 30 minutes while taking a short hike. When I returned and started the truck the dash was black, no gauges, no PRND indication, nothing and the warning lights in the mirrors stayed illuminated continuously. We were in a National monument and decided to try and get back to the visitor center for someplace safe. When I placed the vehicle in what should have been reverse the vehicle rolled back but only because it was on a slope. When I shifted to where drive should be nothing happened. I tried several times as we were now in the traffic lane on a curve. I went completely back to park then cycled to drive and it worked. On the drive to the visitor center I noticed that the blinkers did not work either. Also, what I thought were manual gauges like the speedometer and fuel gauge did not work. When we got to the visitor center the vehicle would not shift into reverse from drive. I had to go back to park and then to reverse. I was able to get the vehicle working by disconnecting the negative battery cable for about 5 minutes. This just happened today and we are 1500 miles from home so the vehicle has not been inspected. If another car would have come around the corner while we were disabled they would have hit us as it is a one way loop so only one traffic lane that we were in.

I own a 2025 Ram 2500 that is affected by Recall 03D involving the Trailer Brake Control Module. This recall is related to a potential failure of the trailer braking system and trailer lighting system, which creates a serious safety risk while towing. I regularly use this truck for towing, and due to this issue, the vehicle may not safely tow trailers, increasing the risk of an accident. I have experienced this issue while towing, all lights will shut off on my trailers and warnings that the trailer has been disconnected repeatedly pop up. Then the lights will flash back on just to repeat again. After this happened the first time (last year), I took my truck in to have them run diagnostics and they were unable to find anything wrong, suggesting it could be the trailer, and now the recall is here. I have contacted my dealer, but the replacement part is not available and has an expected 55 week leadtime due to Stellantis allowing dealers to order only one module per week. There are 55 customers in line ahead of me waiting on this part for their own trucks. This leaves me with a vehicle that cannot be safely used for its intended purpose. I am requesting that the manufacturer expedite parts availability and provide a timely resolution to this safety recall Stellantis should not be allowed to sell anything while all of the current trucks on the road are unsafe.

I have had numerous safety warning messages display upon startup and also while driving. The messages are usually combined with a cold ambient temperature and do not display during warm temperatures. The FCA dealership has attempted to fix this issue on at least six different occasions so far without any change. To date, FCA has replaced the original battery, they have updated, flashed the ECU module, performed NHTSA Recall B4C for flashing the cluster, and most recently they replaced the ORC module. FCA indicated that NHTSA-25V882 was not applicable to my VIN despite my VIN production date in April '25; within your suspect period. Original issue remains, FCA STAR case generated however cannot replicate error condition for FCA engineers. The next scheduled visit to FCA is to replace a telematics module for possible link to issue with the Uconnect5 system. This safety issue was first noted before 800 miles and continues through 2768 miles thus far. As this issue pertains directly to a vital Air Bag sensor issue and the inability to call for a SOS assistance, I expect the NHTSA to raise this concern with FCA USA and to determine the cause of this safety defect and issue a new Recall Notification for repair and/or replacement of affected parts.

My Trailer Control Module failed when I hooked my travel trailer up to my truck to tow for a weekend trip. This was the first time I hooked my 2018 travel trailer to my truck. The lights started blinking erratically and then the module quit responding completely and I was not able to tow without brakes and lights. There is a new recall issued for this part but my VIN isn’t showing up as eligible. I was forced to pay out of pocket to have my TCM replaced because they tried to blame my trailer. The trailer worked fine on my 2016 Ram 2500. The trailer worked fine on my father’s 2019 Ram 2500 and it works fine now with the new trailer control module installed. Now there is a recall issued but my truck maybe doesn’t fall within the listed dates? However, I have experienced the failure that is being recalled.

Feb 9, 2026Electrical systemEngineLane Departure

Subject: Safety Concern – Vehicle Shuts Down While Driving / Request for Replacement Despite multiple warranty repair attempts, my 2025 Ram 2500 continues to experience unresolved electrical failures. In addition to the previously documented issues, the vehicle shuts down while driving, forcing me to immediately pull over, place the vehicle in park, and restart the engine in order to continue driving. This condition has occurred unexpectedly and without warning. Losing power while the vehicle is in motion presents a serious safety risk, especially during highway or interstate driving. Given that I rely on this truck for work and frequently travel long distances between New Jersey and Texas, this behavior makes the vehicle unsafe and unreliable for its intended use. The truck has already undergone repeated diagnostics, module replacements, software updates, wiring repairs, and battery replacement at authorized Ram dealerships. Despite these efforts, the issue persists. At this point, I have lost confidence in the safety and reliability of this vehicle and do not feel comfortable continuing to drive or own it. I have acted in good faith and allowed multiple opportunities to repair the vehicle. The ongoing shutdowns while driving demonstrate that the defect has not been corrected within a reasonable number of attempts. Requested Resolution: • Immediate escalation of this case due to a safety-related defect • Replacement of the vehicle or trade-assist into another Ram truck • Reimbursement for loss-of-use expenses incurred due to repeated service visits I am requesting a definitive resolution rather than additional repair attempts.

While driving in 4x4 on a snow covered road, the truck simultaneously got a check engine light as well as several other error messages to include service required to the emergency braking and the trailer brake controller. At the same time, the full exhaust brake engaged without any driver input and caused a sudden slowing of the truck's tires on a slippery surface. The owners manual specifically warns "Do not use the exhaust brake feature when driving in icy or slippery conditions as the increased engine braking can cause the rear wheels to slide and the vehicle to swing around with the possible loss of vehicle control, which may cause a collision possibly resulting in personal injury or death." Fortunately I had a lot of weight in the truck when this happened and I was able to control it, but a malfunction that turns on the full exhaust brake, especially while 4x4 is engaged, is dangerous enough that there is a warning in the manual. This happened twice. I had a solid check engine light on, and the following day while waiting for a service appointment, a slew of new warnings were flashing across the screen, locking the transmission in 6th gear, advising the 4x4 was no longer available, and may others. I attempted to shift from drive to reverse, the gear shifter locked itself in park. I shut the truck off to try restarting it and moving it, but there was no power getting to the truck to use the sos button to call for help in a poor cell reception area, no lighting worked while obstructing half of a travel lane on the roadway. The truck had good voltage prior to this. The truck was towed to the dealer with 5100 miles on it.

The instrument cluster failed completely. All gauges were offline, and the vehicle became stuck in the ACC/IGN “on” state. The push-to-start button would not disengage, the exterior lights stayed on, and the truck acted as if the ignition was on even when the engine was off. While driving, no speedometer, RPM, warning lights, temperature readings, DEF/emissions information, airbag indicators, or other instrument cluster functions were available. The vehicle also displayed a false door-open message. The issue was confirmed by the dealership, and the truck was declared unsafe to drive. The vehicle has remained out of service for months while waiting for the replacement instrument cluster, which has been unavailable due to manufacturer part shortages. The problem can be reproduced and is fully documented by the service center.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2025 Ram Ram 2500 Mega Cab verdict →
