Ram filed this with NHTSA as a service bulletin dated Jun 17, 2025, received Jun 18, 2025, about the electrical system. It names 1 model year (2025). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communication"Receiver Module 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. - If the sensors are loose, fix them to the wheel properly. - If there are aftermarket parts that can potentially affect the TPMS functions, any repairs will not be considered for warranty."

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 371 complaints with NHTSA since 2015. 193 of them name Electrical System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2025 Ram 1500, the 27 owners who gave an odometer reading for Electrical System reported it at a median of 6,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Brand new 2025 ram 1500 is out of alignment at 800 miles. It pulls to the right. On highway, it almost turns itself to the other lane. Major disaster maker

Common questions
Source: NHTSA, 49 CFR 579.5Is Ram 9100593REV1 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the 9100593REV1 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Stellantis warranty extension on file lists the ones Stellantis has filed.
Which vehicles does 9100593REV1 cover?
The manufacturer filed it against 1 model year: 2025 Ram 1500. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
