2025 RAM 1500

Date: November 12, 2025 Vehicle: 2025 Ram 1500 Big Horn 3.0 Dealer: Frank Boucher Chrysler Dodge Jeep Ram of Janesville – 4001 Milton Ave, Janesville, WI 53546 I have been experiencing ongoing electrical and instrument cluster failures with my 2025 Ram 1500 Big Horn 3.0 since purchase. The most serious issue is a recurring message: “Warning Light Illumination Cannot Be Shown – Service Required.” This means the cluster cannot guarantee display of safety alerts such as the check engine, airbag, brake, or oil pressure lights. This is a major safety hazard because I may not be warned of a system failure while driving. The truck also shows false “Trailer Light Out” warnings when no trailer is connected, indicating a fault in the Body Control Module (BCM) or CAN bus communication. This may cause incorrect trailer or brake-light behavior, putting other drivers at risk if brake or turn-signal lighting fails to operate properly. It also displays a false “Too Much Oil” warning despite normal levels, and the 3.0 engine has no dipstick, preventing manual verification. The truck has also failed to start multiple times with both the remote fob and manual ignition. On November 12, 2025, it would not start at all; after several attempts, it started with the check engine light briefly on, then it turned off on its own. I have brought the vehicle to the dealer twice. Technicians confirmed Dodge/Stellantis is aware of the defect but said no repair or software update currently exists. The issue has been reproduced and documented. Based on symptoms and dealer feedback, this is likely a BCM or instrument cluster communication fault within the vehicle’s CAN network, affecting ignition, lighting, and safety indicator functions. It directly violates FMVSS 101 (controls and displays) and poses a serious road-safety risk. I request a full NHTSA investigation and recall for this defect, as it affects multiple Ram 1500 models and leaves drivers unaware of critical system failures.

The contact owns a 2025 Ram 1500. The contact stated that immediately after purchasing the vehicle, the contact experienced issues with the brakes. The contact stated that while driving at 80 MPH, several messages were displayed on the instrument panel. The ABS warning light and other unknown warning lights were illuminated. The brake pedal was depressed but traveled down to the floorboard, and the vehicle failed to respond immediately. The vehicle eventually came to a rolling stop. The contact was able to continue driving. The contact stated that the failure persisted. The contact stated that on a separate occasion, while reversing out of the driveway, several messages were displayed on the instrument panel. The vehicle was taken to the dealer. The contact stated that the brakes failed while at the dealer while an employee was test driving the vehicle. However, no cause for the failure was found. The dealer replaced the auxiliary battery, and the park assist module was reprogrammed. The contact stated that the failure persisted. The vehicle was taken back to the dealer, where it was diagnosed and determined that the blind spot sensor had failed. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 1,504.

The digital instrument cluster failed. All telemetry is shown on this cluster including speed, fuel level, rpm, odometer and more. The cluster was going totally black every two minutes and it would disable cruise, lane departure warning, blind spot warning and the check engine light was on. There was no indication prior that there was a problem, it just all of a sudden went black and beeped. Then it would come back after 5 seconds and do it again two minutes later. Also my odometer wasn't working or updating the miles. The dealer confirmed the cluster needed to be replaced. It sat at the dealer for 96 days before the repair was made.

My 2025 Ram 1500 Big Horn, ~6,000 miles) experienced a steering-assist failure and then a ruptured coolant hose that sprayed coolant over electronics. Dealer (Hendrick Hoover) refused warranty service and instructed me to leave their property. Ram Customer Care told me to drive the unsafe truck home while my child was onboard. The vehicle is now inoperable and unsafe. I have photos and video of the leak and the dealer refusing service. I request an urgent safety investigation and that NHTSA notify Stellantis that my vehicle presents a clear safety risk.

Upon starting my vehicle, numerous warning lamps/messages appeared to include: - "Service Electronic Stability Control" - "4WD System Temporarily Unavailable" - "Auto Emergency Braking (AEB) Off" - "Blind Spot Alert Unavailable Service Required" (the blind spot indicator lights on the side mirrors were also illuminated) In addition to the above warnings, I no longer had electronic power steering, making the vehicle nearly impossible to turn. Thankfully I was parked when all of this occurred. Had I been driving, the loss of power steering alone could have been catastrophic. I shut down the vehicle hoping that the issues would resolve upon restart. Unfortunately they did not. It took multiple more shutdowns/restarts and approximately 20 minutes before the problems disappeared and the vehicle seemed to be functioning properly. I immediately drove the vehicle to the dealership for service. As of this writing, they have not been able to replicate the problem nor find a cause.

Vehicle has been taken to the dealership for AEB and blind spot monitoring. The vehicle has spent 15 days in the shop, only for nothing to have changed. Vehicle was driven by dealership an excessive 171 miles, only to be returned to us and within 10 minutes of driving, the AEB warning reappears. This vehicle has driven less than 5000mi. It should not have such electrical issues impacting enhanced safety features. The truck is going back to the dealership for yet another attempt to repair, unlikely to be successful. A quick online search leads to numerous individuals experiencing the same issue with their Ram truck with seemingly no resolution in site outside of replacing the CADM module. It's absurd that this hasn't been issued as a formal recall.

Constantly getting warnings that Auto emergecy braking, blind spot monitoring, and forward collision is disabled and needs service. It flashes on and off on the dash at inconsistent rates and appears to be bad wiring connections or faulty equipment. Been to dealer numerous times and still not fixed. I feel like these systems are going to fail me and could cause a potential safety concern.

When I test drive the truck it had approximately 20 miles on it. There was a yellow warning light on that indicated there was a trailer attached and the blind spot monitoring was deactivated. The salesman said it was just a glitch and they would get it fixed. I bought the truck a few days later and it had many more miles on it. The warning light was still on and the salesman said he would take it to get repaired while I was finishing the paperwork. After waiting over 3 hours he brought the truck to me. When I got in to drive home the warning light was still on. I asked him and he said they couldn’t gix it but it wasn’t important and I could come back later. I made an appointment for the next Monday. They kept the truck over 12 hours and said the had to order a part but it was safe to drive. Weeks later I brought the truck back and again it was there from open to close and it wasn’t fixed. This time they said it wasn’t safe to drive and I had to leave it there until they could fix it. It wasn’t safe there appropriately 30 days and they called and said they couldn’t fix it and to come and pick it up. The warning light was still on and the blue nd spot monitor still isn’t working. Now it comes on and off randomly and makes a great amount of noise as the alarms go off and on.

UConnect "requires service" message since 2nd month of ownership. When this error activates, the Emergency call function becomes unoperational. Also, at times, the error popup comes up when I am backing up into a busy street. This is a critical safety issue!! Multiple trips to the dealer since last year. The issue is not fixed. Lane Keep Assist issue: The sequence: When changing parameters In UConnect 1- Select Vehicle tab 2- Select Safety & driving assistance 3- Select Active lane management 4- Attempts to change any parameters result in (Setting failed, setting not saved please try again All of these issues are a major safty concern for me and my family.

The instrument cluster panel went blank for over 40 miles, despite us stopping, shutting off and restarting, etc. We had no idea what speed we were going or any of the metrics monitored by the instrument cluster like turn signals, fuel level, engine temperature, etc. No cruise control. We took it to an auto parts store that captured the error code U0155. The RAM app on my Iphone also sent a warning that the blind spot monitoring failed. I will be bringing it to Champion Chrysler Dodge Ram in Lansing, MI, on 7/7/2025 and do not intend to take it back until this problem is resolved. While the instrument cluster panel went back to normal since then, how can I be assured it will not fault again and what safety protocols can I rely upon?
