What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 970 complaints with NHTSA since 2015. 41 of them name Fuel/Propulsion 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.
My Jeep over the last year has automatically put itself into park while I’m driving down the highway! I’ve had near miss accidents due to this. No warning lights, no signs something is wrong. It just either slams itself into park and locks up, then won’t turn off.

Common questions
Source: NHTSA, 49 CFR 579.5Is Jeep 9100858 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 9100858 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 9100858 cover?
The manufacturer filed it against 2 model years: 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.
