Rapid Response Transmittals (RRTs) 2025

[Samo]

Hello, just got advised by dealer to book truck in for the following RRTs: 25-237, 25-238 and 25-239

Anyone know what these are or how urgent? Vehicle is a 2025 Ram 1500 Limited

Thank you

I'm interested in the third one listed, RRT 25-237 – DPTCADMUPDATE (ADAS / CADM update). Like quite a few others, I've had errors pop up randomly for Blind Spot Monitoring (BSM) and Forward Collision Warning (FCW). When this happens, the BSM lights on the side mirrors stay lit all the time. I've been lucky in that if I shut the truck off and let it completely shut down, it resets the error. I haven't specifically noticed the ADAS Unavailable error, but since several errors flash by, it might've been there. I wonder if this RRT would help me. I'm going to print it out and bring it in to dealer when I take it in for the CSN for the purge valve hose.
