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 owners reported
Source: NHTSA complaint databaseOwners of the 7 model years this bulletin names have filed 1,880 complaints with NHTSA since 2015. 858 of them name Electrical System, Service Brakes — 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 2022 Jeep Wrangler, the 23 owners who gave an odometer reading for Electrical System reported it at a median of 30,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

The Forward Collison icon is on, on my dash. I get a screen message the service is not working, then another to say the signal is lost. I cannot reprogram/reconnect the service in Uconnect. Makes no difference for icon whether engine is running or not. This started in November 2023. The dealer is saying sensor needs replaced.

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 Stellantis 9100186 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 9100186 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 9100186 cover?
The manufacturer filed it against 7 model years across 3 brands (Jeep, Ram and Dodge): 2023 Dodge Hornet, 2023 Jeep Compass, 2022 Jeep Compass, 2023 Jeep Wrangler, 2022 Jeep Wrangler, 2023 Ram 1500 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
