The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 59 complaints with NHTSA since 2015. 27 of them name Service Brakes, 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.
The brake pedal on my truck is very spongy. It goes halfway to the floor if it isn't pumped at least 2 times before braking. I find it very distressing in tight situations where I do not have time to pump before braking. I took it to the dealership and they say there is nothing wrong. This is a brand new truck

Common questions
Source: NHTSA, 49 CFR 579.5Is Ram S2505000002 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 S2505000002 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 S2505000002 cover?
The manufacturer filed it against 1 model year: 2024 Ram 2500. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
