What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 109 complaints with NHTSA since 2015. 11 of them name Engine — 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.
The contact owns a 2025 Ram 3500. The contact stated that while driving approximately 60 MPH, several unknown warning lights illuminated, and the vehicle stalled. The vehicle was towed to a dealer where it was diagnosed, and determined that several repairs were needed, and there was an issue with the battery.

Check engine light consistently comes on with codes p0263, p0272, p0266 for contribution balance codes for cylinders 1, 2, 4 & 5. Truck runs rough. Dealership says it’s a 5-8 week process to test and get injectors into replace if that’s the issue.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ram S2518000002 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 S2518000002 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 S2518000002 cover?
The manufacturer filed it against 4 model years: 2025 Ram 2500, 2025 Ram 3500, 2025 Ram 4500, 2025 Ram 5500. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
