2025 Ram 2500 Electrical System Problems

The engine will shut off at random times without warning causing the vehicle to stop suddenly

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 infotainment display continues to flicker after the B4C safety recall was completed at the dealer. This is quite distracting while driving

The contact 2025 Ram 2500. The contact received notification of NHTSA Campaign Number: 26V059000 (Exterior Lighting, Electrical System). The dealer was contacted to schedule an appointment; however, the dealer informed the contact that the part to do the recall repair was not yet available because the manufacturer instructed the dealers that the parts should be prioritized for fleet vehicles first. The contact stated that while driving at an undisclosed speed uphill and hauling a load, the vehicle failed to respond while depressing the brake pedal. The vehicle decelerated while driving up the incline. The vehicle was not diagnosed or repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not contacted. The failure mileage was approximately 2,000.

All warning lights flash for trailer when connected. ( CHECK TRAILER CONNECTION, TAILER BRAKE DISCONNECT, SERVICE TRAILER BRAKE SYSTEM) More active when dark out.(early morning, nights). Same error with different trailers.

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.

The contact owns a 2025 Ram 2500. The contact stated that while driving with a trailer hitched to the vehicle, the manual brake controller flashed an unknown error message on the instrument panel. Due to the failure, the tires on the trailer locked up and failed to operate as needed. The contact received notification of NHTSA Campaign Number: 26V059000 (EXTERIOR LIGHTING, ELECTRICAL SYSTEM); however, the part to do the recall repair was not yet available. The local dealer was made aware of the issue and confirmed that parts were not yet 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 informed the contact that parts would not be available for almost two years. The vehicle was not repaired. The failure mileage was unknown.

Instrument cluster would not turn on in the truck. I turned truck off 2 times and would not power on. I was unable to tell Speed, Fuel level, DEF level or any warning indicator that would have pop up if there was an issue with the truck. Once I made it to my destination came back 15 minutes later the cluster started working again.

The contact owns a 2025 Ram 2500. The contact stated that while driving at an undisclosed speed, the instrument cluster went blank, failing to display pertinent vehicle information. Afterwards, the message that the MIL was not functioning properly was displayed. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the instrument cluster software. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 1,200.

instrument cluster goes dark while driving , ADAS malfunctions until instrument cluster restarts . Unknown speed until restart, no ADAS until restart confirmed by dealer parts not available ,dealer stated "cant inquire about parts until 11/29 Problem started 9/29, no warning lamps , cluster goes dark

Trailer lights not working properly, the marker lights flash when turn headlights on loss of brake and turn signal lights. Hooked another ram 2500 up and did same then hooked a 2013 ram and a 2021 Yukon up and all lights on trailer worked as it should. Have contacted dealer they are saying they never heard of, then at another dealer they are saying they have 4 rams with this issue and it’s with the trailer module and one was even melted. Saftey issue to me because if I’m driving my camper with my kids in it and we have no proper lighting to avoid being hit or if it melts and causes a vehicle fire

On Sunday, 9/14/25 driving on a 70 MPH interstate highway, pulling a trailer behind the Newly-purchased 2025 truck (only 700 miles on it), the road narrowed down to one lane because of a traffic obstruction and cones. As I slowed down to about 35 mph and then went to speed up again as the traffic eased, the vehicle provided a ping notification sound and the Electronic Vehicular Instrument Cluster (EVIC) display stated something to the effect of "Shift into 'P' to start vehicle". I realized that the vehicle was not responsive as expected, indicating power steering had failed, likely because the engine was off. I'm uncertain whether the steering wheel was locked, which is likely, because at that speed, only a very slight turn of the wheel was needed to move into the closed lane on the straight road. I continued to coast to get the vehicle and trailer over to the right, hugging the cones which were mid-lane in the closed lane, allowing other cars to go around me while I came to a complete stop on the interstate to shift into Park. Once I could get the gearshift into Park, I started the vehicle again, at which point it drove normally. The trailer had been weighed just that morning and both tongue and overall weight were well within the capacity of the vehicle. It was hooked up to the electrical systems of the tow vehicle via the 7-pin connector. I had the EVIC set to show vehicular information - oil pressure, oil temperature, etc. I similarly had information like battery voltage displayed on a widget on the uconnect screen. Everything looked nominal. No error code was logged to my knowledge. I have since seen similar reports from other 2025 RAM owners in NHTSA complaints and on social media. My dealership is unaware of these issues having been reported elsewhere, so they are starting from scratch in finding a diagnosis on a seemingly intermittent issue. That process is ongoing at this time.

While driving my 2025 RAM 2500, the entire digital dash is intermittently going dark and will stay dark for several minutes, powering back up and functions as it should then goes back out. This presents the possibility for significant hazard potential as all visual indicators for speed etc are lost. The vehicle loses the ability to use turn signals as well as many other functions while this is occurring.

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.

When turn signal auto-cancels (completion of turn), the opposite side turn signal will SOMETIMES erroneously enable. This can be consistently reproduced when completing a turn (returning wheel to center) quickly. Slow turns do not cause the problem. Took to dealer and showed them how to reproduce... In park, just turn on signal then simulate turning then returning to center quickly. Dealer tested another 2025 on the lot and confirmed same behavior. They told me this is normal behavior. This happens sometimes under normal driving conditions and I'm afraid it confuses cars around me and presents a potential safety issue.

Purchased above vehicle on 7/12/25. Was advised no towing for 1st 500 miles. At 712 miles, I hooked my fishing boat up to the truck to go fishing. Initially, truck did not recognize my boat trailer lights (marker and tail lights). My previous truck was a 2023 Ram 2500 rebel that never had an issue with connecting my boat trailer electrical system. All lights worked as should. I still have the same boat trailer as previous(2020 shore lander trailer with led lights). The new procedure for my 2025 Ram 2500 is to disconnect the 7 pin trailer electrical connector to the truck, stop the trucks engine, reconnect the 7pin to the truck outlet and maybe it will, maybe it will not work. There has been times I've had to stop and restarted the truck 8-10 times before the trailer is recognized. Once it is recognized, I have little or no faith in the trucks electrical system to safely tow my boat to go fishing. I also check all brake, hazard and turn signals are functional on the boat trailer while still in my driveway before entering onto a main highway, but I have no way of checking to see if the trailer taillights are properly functioning while traveling on any roadway or highway. This intermittent function can cause a serious hazard not only for myself, but for other motorists who do not see the trailer lights, turning signals or braking signals. On 8/4/25, my Ram truck went in for service at Diehl Ram Jeep Chrysler in Grove City, PA for analysis and repair for these trailer lighting connection issues. Service tech at Diehls "reflashed and updated" the ECM which did not fix the problem. I have another appointment on 8/11/25 for this issue to be escalated with Ram Customer Care.

While driving at a low speed vehicle has shut down and VIC says shift into park to start once you shift the vehicle into park you can restart it . This has happened twice and no computer codes are stored.

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.

Intermittent blackout of driver display screen while vehicle is running. Also, intermittent blackout of navigation screen on 14.4 inch display screen while vehicle is running.

When letting off the gas and coasting to turn on a road around 10 mph, vehicle motor shut off and lost power steering control. Vehicle alerted to place vehicle in park, press break and push start button. Vehicle started back with no issues. Reported to dealer, dealer picked up and stated they could not find any issues and returned to me. Following day while going to work vehicle again shut off when pulling up to a gate entry and then again approaching my return to home at stop sign. All three times vehicle was under 15 mph and approaching turn/stop. New Truck, only 30 miles on it when first incident occurred and only 160 miles now. Dealer still not able to duplicate or locate the problem. System is showing no codes.
