Read by machine from the document NHTSA serves (1 page), read Sep 29, 2026. A part number is shown only where it matches Jeep’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 2,104 complaints with NHTSA since 2015. 457 of them name Power Train, Steering, Suspension — 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 2023 Jeep Grand Cherokee, the 19 owners who gave an odometer reading for Suspension reported it at a median of 42,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
I own a 2023 Jeep Grand Cherokee. On August 18, 2025, the rear suspension coil detached and fell off in my driveway. I had the vehicle repaired at an authorized Jeep dealership. However, on **August 31, 2025 — just 13 days later — the exact same coil spring detached again, this time while I was driving at freeway speeds.

May 16,2025 my power steering light came on. I checked the fluid, and when I turned it back on it was gone. The next day, I started driving all my safety lights in dash & mirrors came on. When I pulled into my kids school it made a strange noise. I then drove right across the street to Lees tires.

Common questions
Source: NHTSA, 49 CFR 579.5Is Jeep S2521000004 Rev. A 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 S2521000004 Rev. A 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 S2521000004 Rev. A cover?
The manufacturer filed it against 6 model years: 2026 Jeep Grand Cherokee, 2025 Jeep Grand Cherokee, 2024 Jeep Grand Cherokee, 2023 Jeep Grand Cherokee, 2022 Jeep Grand Cherokee, 2021 Jeep Grand Cherokee. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
