2025 RAM 1500 Forward Collision Avoidance Adaptive Cruise Control Problems

Shortly after purchasing the vehicle, I began experiencing intermittent electrical and driver assistance system malfunctions. These issues included warning messages, unexpected system behavior, and periods where multiple advanced driver assistance features were unavailable or disabled. The problem first occurred around April 4, 2025, at approximately 665 miles. Since then, the issue has occurred intermittently and has been difficult to predict or reliably reproduce. I brought the vehicle to an authorized dealer multiple times for warranty repair. On at least one visit, the dealer was unable to duplicate the concern. On subsequent visits, the dealer performed warranty-related diagnostics and repairs; however, the original issues have not been clearly confirmed as resolved. At times, the vehicle was deemed drivable but not confirmed to be fully repaired. Manufacturer technical assistance (STAR/engineering) has been involved in reviewing data and test results. As of the most recent service visit, the vehicle remains under review, and...

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...

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.

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.

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

Purchased a 2025 RAM 1500 TUNGSTEN on [XXX]. Within a week of purchase, the blind spot monitors, forward collision monitors, and the emergency braking all quick working. The first attempt to fix was replacing wiring. This stopped it for a week before they were back on. Goes back into shop and replace and fully charge batteries and again it lasted about a week. Two more trips to shop (3rd and 4th visits) for same issues with more "quick fixes". Fifth attempt to fix took a couple weeks and had a module replaced. which lasted for about 3 weeks. After a trip to Florida in April it had to go in to shop again for the same issues. This time is spent 7 weeks in the shop, replaced multiple modules and other trial and error pieces before it was "fixed" again. Got vehicle back in June and it ran good until...

Adaptive cruise control does not work, Forward collision warning does not work, pedestrian emergency braking does not work, auto emergency braking does not work among other non safety issues. Dealer is aware and has ordered a new infotainment system which controls all these safety features but is unable to get it from the manufacturer for the last 6 months. This system did not work from the day I picked up the vehicle

I am submitting this formal safety complaint regarding my 2025 RAM 1500 Limited, which I purchased new in November 2024 and currently with approximately 9,000 miles. The vehicle has exhibited repeated, dangerous failures of its advanced driver assistance and braking systems that place both the driver and public at serious risk. Summary of Safety Incidents: First Incident: While driving at approximately 35 mph, the vehicle abruptly and uncommandedly stopped, with no driver input. Fortunately, there were no vehicles behind me at the time, or this could have resulted in a high-speed rear-end collision. Second Incident: Roughly 400 miles later, while stopped at a traffic light, the vehicle displayed multiple warning alerts and shut itself off completely. Upon restarting and driving approximately 50 yards, the braking system failed for about five seconds, rendering the truck unable to stop. This failure was later replicated by the authorized dealership’s service team, who then...

The windshield of my 2025 Ram 1500 Big Horn was damaged by road debris and requires replacement. However, the manufacturer (FCA US LLC/Stellantis) has failed to supply the replacement windshield, rendering my vehicle undrivable for an extended period due to their inadequate parts supply chain. This delay creates a major safety risk because the vehicle cannot be driven legally or safely without a windshield. In emergency situations, the vehicle would be unusable, and I have incurred significant financial harm due to its inoperability. A new vehicle should not have months-long delays for critical safety components. The OEM supplier (Carlex) has confirmed that the windshield is in stock and available to ship, meaning the issue is due entirely to FCA's failure to place the order or manage their supply chain. This demonstrates negligence in FCA/Stellantis' parts supply chain, impacting customers who require essential repairs. This issue is not an isolated incident...
