The contact owns a 2025 Ram 1500. The contact stated that while driving with cruise control engaged, the cruise control system accelerated and failed to recognize objects or vehicles ahead. The contact was forced to manually override the cruise control system to regain control of the vehicle and prevent an accident. The contact stated that a "Driver Override" warning message appeared on the instrument panel as the vehicle accelerated without the contact depressing the accelerator pedal. A dealer was notified of the failure, and an appointment was scheduled to have the vehicle inspected. The manufacturer was not yet notified of the failure. The vehicle was not yet repaired. The failure mileage was approximately 17,000.

While driving in traffic on the interstate with adaptive cruise control working, all lights on the dash illuminated for 1 to 2 seconds, adaptive cruise control kicked off, the dash then went totally blank for 2 to 3 seconds then slowly came back to life with the fuel gauge showing zero when there was ¾ of a tank prior to this event.

My infotainment screen makes a loud buzzing noise at least 3days per week, and then it shuts down and reboots itself, this happened several times while backing out of parking spots and I lost my rear view camera, also sometimes while driving on the Highway both of my blind spot monitor lights on my mirrors will come on and my truck will display BMS malfunction and this stops my adaptive Cruise and hands free Cruise while driving on Highway at 65mph or higher. I've taken in to the dealership and they say they can't reproduce the problem with the buzzing coming from The infotainment system, and the Blindspot Monitoring System will self correct after my vehicle sits overnight, but my RAM documents the BMS and sends me an alert to take into dealership for service, but once again the dealerships say they can't replicate the issue with the bms.

On November 16th while on vacation and traveling through west Texas, our 2025 Ram 1500 SST Lonestar cancelled our adaptive cruise and automatic emergency brake. A message popped up again stating "Auto Emergency Braking (AEB)/ACC Unavailable Service Required". We were pulling our travel trailer and we found that if we shut off vehicle, it would reset and appear to work for a short time but would them cancel our adaptive cruise and automatic emergency brake. On November 17th we took it to Sisbarro CDJR in Deming, NM and they claimed they couldn't verify our problem with a 30 minute text drive. So their tech did an update to the PCM and gave us the truck back. We hitched up the next day and with 15 minutes the problem happened again. We stopped using the adaptive cruise control and started using the regular cruise. The message continued and we continued to Surprise, AZ without the ACC and AEB. On Monday, November 24th, we took the vehicle to Larry Miller CDJR in Surprise, AZ. After I described the ongoing problem to the service writer, he told that it would be 3 or 4 days before they could look at it and it could take at least an additional 2 days to repair if they could recreate the problem. I asked him if he thought it was safe to drive back to Mansfield, TX and he said it should be okay. Over the next three days we returned home and continued to have the problem with the ACC and AEB warning. I've have called Classic CDJR in Arlington, TX and scheduled an appointment for Tuesday, December 2nd at 7 am.

I do not believe my truck's forward collision warning and emergency braking work. I have had a few very close calls with rearending a vehicle in front of me and the truck did not brake automatically or give any collision warning. Also, the adaptive cruise control is set on the furthest distance, but it follows very closely to the vehicle in front of me. Like a 1.5 second length at the most. When I change the setting to follow closer, it will follow a vehicle within inches. I believe this causes a safety issue with a potential crash.

Driving on the highway with cruise control set, heard a beep and looked at my instrument cluster. Cluster went blank, cruise control turned off, lane management turned off. Then another beep turned on instrument panel and now was frozen at 0 as I was driving at highway speed. Next I was stopped at the off ramp and instrument panel said I was doing 57. I have videos of it happening. And it is in a constant frozen to reboot stage

All major braking and safety systems have failed, including the parking brake, 4-wheel drive, cruise and adaptive cruise control, lane departure warnings, blind spot monitoring, and parking collision alerts. These failures occurred at the same time, and we believe there may be additional issues not yet identified. Our local dealership (Barry Sanders Supercenter, Stillwater, OK) attempted multiple repairs before opening a service ticket with RAM/Stellantis. We were informed the part needed to fix the problem is backordered for approximately one year. This extended delay means we must continue driving a vehicle without critical safety systems or park it indefinitely, creating both a financial and safety burden. The loss of these features greatly increases the risk of collisions, especially in bad weather or on highways where adaptive cruise, lane departure warnings, and blind spot detection are essential. Online searches show this is not an isolated issue but a recurring problem in 2025 RAM 1500 models, suggesting a broader manufacturing or design defect.

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?

Vehicle: 2025 Ram 1500 RHO (base trim) VIN: [XXX] Build Date: [XXX] Purchase Date: [XXX] Mileage at first occurrence: ≈ 40 miles (issue began immediately after delivery) Mileage now: [insert current mileage] Problem Description The instrument cluster (IPC) repeatedly reboots while driving or upon each key cycle. Every restart forces the odometer to reset and display 40 miles, erasing the accurate accumulated mileage. Simultaneously, the vehicle fails to retain any infotainment or vehicle-settings data (radio presets, climate preferences, drive modes, seat/mirror memory). This occurs 100 % of the time with every ignition cycle and has happened on every drive since purchase. Safety Concern A rebooting cluster distracts the driver, removes access to critical information (speedometer, warning lights), and falsifies odometer readings—potentially masking future maintenance intervals and impairing resale/title accuracy. The loss of settings can also disable previously selected safety aids (e.g., adaptive cruise presets, lane-keep parameters) without the driver’s knowledge. Attempts to Resolve Hard battery reset performed (negative-terminal disconnect, 30 min). Issue returned on first restart. Awaiting dealer appointment; preliminary research indicates similar complaints among early-production 2025 RHO vehicles and a possible IPC/BCM firmware defect. No official recall or TSB acknowledged for my VIN to date. Frequency Every ignition cycle; cluster reboot typically occurs within 30 seconds of start-up or during the first two minutes of driving. Infotainment/vehicle settings never save between cycles. Events & Dates [XXX]: Vehicle delivered; first reboot observed while exiting dealership lot. 06/29/2025–present: Issue persists on every drive. Requested Action Investigation into potential defective IPC/BCM firmware or hardware causing repeated reboots and odometer data loss on 2025 Ram 1500 RHO models built in April 2025.
