Jeep filed this with NHTSA as a service bulletin dated May 18, 2026, received May 28, 2026, about the suspension. 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.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationClunking when going over bumps, potholes, or turns. During diagnosis dealers may find rubber separating from the bushing on the handling link (SOL S2102000004 Rev C. for reference). This is normal and most likely is not attributed to the noise. Please follow normal diagnosis and ensure all tie-rod and ball joints are properly torqued and if worn, replace. If diagnosis leads to lower control arm replacement, the tension link(s) should be replaced first then test driven to ensure noise has disappeared before any handling link replacements.

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. 102 of them name 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 18 owners who gave an odometer reading for Suspension reported it at a median of 46,000 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.

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 Jeep 9100811 REV1 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 9100811 REV1 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 9100811 REV1 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.
