What it saysThe customer states the ABS and Traction Control warning comes on. NHTSA’s full summary ↓
Jeep filed this with NHTSA as a service bulletin dated Dec 17, 2025, received Dec 23, 2025, about the service brakes. It names 6 model years (2021–2026). 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.

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 6 model years this bulletin names have filed 2,014 complaints with NHTSA since 2015. 207 of them name Power Train — 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 2021 Jeep Grand Cherokee, the 15 owners who gave an odometer reading for Power Train reported it at a median of 34,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
On April 20, 2026, my 2025 Jeep Grand Cherokee L was involved in a crash due to a sudden and complete brake failure. At the time of the incident, the vehicle was in the custody of an authorized FCA dealership. An employee of the dealership was operating the vehicle when the brakes completely failed to respond, resulting in an accident.

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.

Source: NHTSA, 49 CFR 579.5Is Jeep S2521000005 a recall?

Is the S2521000005 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.
