NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
The contact owns a 2023 Jeep Wagoneer. The contact received notification of Customer Satisfaction Program 13B (Power Train); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair.

2024 Jeep Wagoneer · Power Train · filed with NHTSA Jul 2, 2026
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 9100437Rev1 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 9100437Rev1 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 9100437Rev1 cover?
The manufacturer filed it against 9 model years: 2025 Jeep Grand Cherokee, 2024 Jeep Grand Cherokee, 2023 Jeep Grand Cherokee, 2025 Jeep Grand Wagoneer, 2024 Jeep Grand Wagoneer, 2023 Jeep Grand Wagoneer and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
