NHTSA Complaint #11702232 — 2025 RAM 1500

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.
