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 545 complaints with NHTSA since 2015. 185 of them name Engine — 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.
As I was pulling up to a red light, the vehicle threw itself into park and completely stopped and would not move. I was unable to put gear into drive. Thankfully, I was not going at full speed. After a couple minutes, I was able to put my foot on brake to restart the car. At this point, the engine and battery light were on as well.

While traveling on San Marcos Highway between Luling and San Marcos at 65 MPH, the vehicle began to lose speed and I realized the engine was no longer powering the vehicle. No warning indicators other than an unresponsive throttle. I was able to coast off onto the shoulder and bring the vehicle to a stop.

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 S2308000122 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 S2308000122 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 S2308000122 cover?
The manufacturer filed it against 6 model years: 2024 Jeep Grand Wagoneer, 2023 Jeep Grand Wagoneer, 2022 Jeep Grand Wagoneer, 2024 Jeep Wagoneer, 2023 Jeep Wagoneer, 2022 Jeep Wagoneer. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
