What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 452 complaints with NHTSA since 2015. 52 of them name Service Brakes — 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 truck brake pedal got hard and went all the way to the bottom. Dash lighted up like a Christmas tree. Luckily I was entering a parking lot so I was going slow and was able to park the truck. Truck only has 453 miles and is only 2 weeks since purchase.
2025 Ram 1500 · Service Brakes · filed with NHTSA Feb 4, 2025
I've owned the truck for only a short period of time. Sometimes when I park it, the truck will not allow me to rengage drive or reverse. Its stuck, as if the parking break is on or some safety feature is locking it from moving.
2026 Ram 1500 · Service Brakes · filed with NHTSA Jan 5, 2026
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 S2605000002 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 S2605000002 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.
Which vehicles does S2605000002 cover?
The manufacturer filed it against 2 model years: 2026 Ram 1500, 2025 Ram 1500. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
