Service bulletins for the 2025 Ram 1500

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

The ambient temperature sensor mounted on the mirror may read higher than expected, sensor must NOT be removed before reviewing the following cases. There are two cases: 1) DTC codes are present, proceed according to the following TSBs: 1.1) 18-031-25 (25 MY DT with DTC: P0071-00 & P0073-00) 1.2) 18-032-25 (25 MY DT with DTC: P0071-00 & P0073-00 for vehicles built on or after July 01, 2024 and before July 29, 2025) 1.3) 08-357-25 (26 MY DT with DTC: P0071-00 & P0073-00) 2) No DTC codes are present, but temperature shown in the cluster/radio is higher than expected, proceed according to SOL S2508000078. To allow the sensor to update properly, drive the vehicle at highway speeds (above 20 MPH) for several miles (15 minutes). This ensures sufficient airflow and temperature sampling for accurate readings. If the temperature still does not update, proceed with standard diagnostic procedures.
