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.

589 on file from NHTSA, as of 2026-10-19.

08-160-25 REV. A2025-07-09. Service bulletin. ELECTRICAL SYSTEM. International Maps Missing Customers may comment on the following: ● The vehicle has North American maps installed instead of the International maps. This bulletin involves inspecting the navigation map region and possibly installing International maps to the radio via USB.
91006222025-07-09. Service bulletin. ENGINE. When replacing a camshaft and parts kit (P/N 68661146xx and/or 68661147xx), it is NOT necessary to order the roller-finger followers (rocker arms) separately, as these are included in the camshaft parts kit.
91006212025-07-09. Service bulletin. STRUCTURE:BODY. For Dealer awareness, 24 MY DT Bed Step does not work for 25MY Trucks and forward. If replacing or installing new rear bed step, note that 24MY Bed Step part number 82215289A$ / 68276196A$ will not work on 25MY Trucks. 25MY Standard Truck requires 82216597A$ / 68582251A$.

91005932025-07-09. Service bulletin. ELECTRICAL SYSTEM. DT25 TPMS Issues - TPMS not working, TPMS working intermittently, TPMS displaying wrong values, TPMS warnings on cluster In case of TPMS concerns, please follow the below: - Verify that the 12V Vehicle battery is good, as low or dead batteries may cause TPMS to not function as designed. - Verify if the RFHM and IPC SWs are up to date. If not, update to the latest SW versions. - Disconnect the Remote Start Antenna Coaxial cable, wait for a minute and plug it back in and verify if the antenna is working as expected, as any issues with it can cause TPMS and Fob issues. - Study the Remote Start Antenna wiring for pinches or damages, as any of these can cause issues with the TPMS and the fob functions. - Perform TPMS Autolearn Procedure After Tire Rotation or Tire Change for Sensata TPM sensors. - Verify if the sensor IDs are correct. If they are incorrect, autolearn the sensors. (Autolearn Procedure - Drive over a speed of 25Kmph or 15 Mph for 20 mins) - If there are any issues in terms of tire pressure, inflate or deflate to the recommended pressure. - If DTCs - C15CB00 ("Front Axle Tire Pressure Placard Implausible") and/or C15CC00 ("Rear Axle Tire Pressure Placard Implausible") are being triggered, program the placard values. Also, check if the placard values were programmed previously. - Please make sure that the Tire placard values match the recommended tire pressure values in case of any TPMS concern. - If the sensors are loose, fix them to the wheel properly. - If an RFH is replaced for any other concern, please program the TPMS sensor IDs into the new RFH and perform the autolearn procedure. - If there are aftermarket parts that can potentially affect the TPMS functions, any repairs will not be considered for warranty. - Aftermarket parts that can impact TPMS functioning: Electrical LED LIGHTING RV equipment, Rear cameras (After Market) Toll Road Transponder Transceivers radios such as FRS /CB. DC/AC inverter Wiring loose grounds. After-market added wiring causing RF coupling Off road / Uplift modifications Aftermarket illuminated splash shields. RFH antenna disconnected. Another aftermarket device introducing RF noise around 433Mhz. Aftermarket GPS devices Aftermarket Wi-Fi hotspots Broken RFH antenna. Nonelectrical Aftermarket devices Steal reinforced tires. Metal Bedliner installed. After Market Tire Incorrect Installation of sensor in winter tires (example TPM upside down) Damages to sensor during tires service Aftermarket Metal splash shields Aftermarket stem valve cup Tinted Glasses (some of them contain metal).

91006142025-06-26. Service bulletin. ENGINE. ADJUSTER Valve Lash Customer's complaint may include a ticking noise coming from the engine. Technician's observations can refer to spongy or stuck hydraulic lash adjusters. Exhaust lash adjusters found with a "spongy" condition (compressible plunger) leading to the assumption of being defective/malfunctioning. EXHAUST lash adjusters are designed to be COMPRESSIBLE by hand. Intake lash adjusters found with a stiff or stuck condition (non-compressible plunger) leading to the assumption of being defective/malfunctioning. INTAKE lash adjusters are designed to be NON COMPRESSIBLE by hand. Do Not Replace EXHAUST lash adjusters when the following condition is present: should be compressible, but they will exert a reactionary spring force during compression and return to full expansion without a compression force. Do Not Replace INTAKE lash adjusters when the following condition is present: should feel very firm and difficult to compress. Once the correct functioning of the intake and exhaust lash adjusters is validated with the procedure above, refer to the Service Manual "HYDRAULIC LIFTER(S) NOISE DIAGNOSIS" procedure. After the corresponding service procedures from the Service Manual involving the Lash Adjusters have been conducted, refer to the detailed instructions in the Service Manual to diagnose and/or service any other component.

This software flash will allow these permanent fault codes to naturally clear. NOTE: If the software update is not completed, customers may have issues with registering vehicle in states with inspections due to the MIL being on (Only an issue if U0104/U0405 have set in life of vehicle). Customers may experience the following: ● **A potential to stall when coming to a stop with an immediate restart. If the engine were to stall while stopping, a message would display in the cluster informing the driver to shift to park to restart the engine.** Other software improvements: ● Improvements related to fault codes P0300, P0301, P0302, P0303, P0304, P0305 and P0306 for cold start catalyst heating misfire..
