What owners reported
Source: NHTSA complaint databaseOwners of the 7 model years this bulletin names have filed 1,835 complaints with NHTSA since 2015. 769 of them name Electrical System — 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 32 owners who gave an odometer reading for Electrical System reported it at a median of 18,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Started with the cold weather in December. I got a notification that I need to service the Power Steering system. Lasted for two drives and then went away. Approximately two weeks later, while driving my family in town, the power steering light came on again. Came to a stop at a stop sign and the car put itself in Park.
2022 Jeep Wagoneer · Electrical System · filed with NHTSA Jan 9, 2023 · ODI 11500823
While driving the Wagoneer it shut down in the middle of road while at a stop light, and did a “hard” reset where all the systems had to boot back up before being able to start the Jeep. I reached out to local Jeep and to Service, and was told to bring it down so that they could run a scan.
2024 Jeep Wagoneer · Electrical System · filed with NHTSA Nov 1, 2026 · ODI 11774976
Generally, for the entire time we've owned the car, it has ongoing and systemic electronics malfunctions. This ranges from the car slamming on its own brakes while driving to systems not working to the seat shifting on its own while driving to false positives in the NAV system, etc.

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 9100386 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 9100386 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 9100386 cover?
The manufacturer filed it against 7 model years: 2024 Jeep Grand Cherokee, 2023 Jeep Grand Cherokee, 2021 Jeep Grand Cherokee, 2024 Jeep Grand Wagoneer, 2022 Jeep Grand Wagoneer, 2024 Jeep Wagoneer and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
