Will not work my brand new camper keeps making light blink when headlights are on and now know lights at all

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

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.

Digital dash cluster became inoperative and the entire gauge went black.

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.

Vehicle's digital instrument cluster failed.

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 co

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.

Unknown. purchase June 2025, 1297 miles on odometer. On 4 occasions engine has died for no apparent reason in traffic. (Specific Hazard is that vehicle must be put in park and brake applied to restart. Very hazardous in traffic especially if pulling a trailer.) In each case vehicle was slowing to make a turn. Signal on and brake lightly applied, Nothing noticed on dash except when notice to put in park and apply brake to Start Engine appears. Dealer has not returned my call for service. Advised them on July 22. Have seen other mention of issue on internet but not this model year and did not notice mention of how hazardous it is to have to come to a complete stop to restart vehicle.

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.

The contact owns a 2025 Ram 2500. The contact stated that while driving at an undisclosed speed, the vehicle stalled with the Diesel Exhaust Fluid (DEF) message displayed. The vehicle was able to restart. The vehicle was taken to the dealer, where it was diagnosed that the Diesel Exhaust Fluid (DEF) system had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 1,700.

The brakes are very inconsistent with a spongy pedal. When a vehicle in front of me caused an emergency stop, the pedal continued to travel almost to the floor and never felt firm. However, if the adaptive cruise control starts to brake first and the brake pedal gets depressed by the driver after that, it feels firm. These brakes are very unsafe on a truck rated to tow as much as these are.

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.

My 2025 RAM 2500 is throwing a P0315 Engine Code. This is part of the NHTSA ID Number: 11016056 and Manufacturer Communication Number: S251800000. Dealer has advised me to not drive the vehicle until there is a fix for it. Truck only has 150 miles on it.
