Stellantis bulletin 9100229
What it saysLIFTER, Hydraulic Roller Deactivating Please do not replace MDS lifters because the disconnecting pin is not lined up, this is normal and not a defect. NHTSA’s full summary ↓
Stellantis filed this with NHTSA as a service bulletin dated Sep 20, 2023, received Oct 30, 2023, about the suspension. It names 245 model years across Jeep, Ram, Dodge, Chrysler, Fiat and Alfa Romeo (2016–2024). 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 201 model years this bulletin names have filed 48,180 complaints with NHTSA since 2015. 930 of them name Suspension — 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 2018 Jeep Wrangler, the 258 owners who gave an odometer reading for Suspension reported it at a median of 8,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The contact owns a 2022 Ram 2500. The contact stated that while operating the vehicle, the warning message "Service Sway Bar" was displayed along with an audible alarm. The vehicle was taken to the local dealer who diagnosed that the sway bar was faulty and needed to be replaced. The sway bar was replaced, and the failure was remedied.

I own a 2023 Jeep Grand Cherokee. On August 18, 2025, the rear suspension coil detached and fell off in my driveway. I had the vehicle repaired at an authorized Jeep dealership. However, on **August 31, 2025 — just 13 days later — the exact same coil spring detached again, this time while I was driving at freeway speeds.

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 9100229 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 9100229 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 9100229 cover?
The manufacturer filed it against 245 model years across 6 brands (Jeep, Ram, Dodge, Chrysler, Fiat and Alfa Romeo): 2020 Alfa Romeo 4C, 2019 Alfa Romeo 4C, 2018 Alfa Romeo 4C, 2017 Alfa Romeo 4C, 2016 Alfa Romeo 4C, 2024 Alfa Romeo Giulia and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
