What owners reported
Source: NHTSA complaint databaseOwners of the 8 model years this bulletin names have filed 651 complaints with NHTSA since 2015. 91 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 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

I was involved in an accident on May 3rd. 2024. As a result of this accident, I have filed an insurance claim. My brakes failed to stop the truck properly. I was pushing the brake pedal as hard as I could, and the brakes were not stopping the truck properly. It had minimal braking not enough to stop the truck.

The brakes do not apply until after the pedal reaches half of its travel distance and still not as good they should. Very soft pedal feeling and too long of pedal travel to apply brakes. Very unsafe! I have had it to the dealer 3 times for this condition since I had purchased it (New) on June 5, 2025.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ram 9100579 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 9100579 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 9100579 cover?
The manufacturer filed it against 16 model years: 2025 Ram 2500, 2024 Ram 2500, 2023 Ram 2500, 2022 Ram 2500, 2025 Ram 3500, 2024 Ram 3500 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
