Stellantis bulletin 9100409

What it saysTRANSFER CASE Before replacing a transfer case unit for fault codes C1444-98 and/or C1477-4B, be sure to reference TSB 21-048-24 for potential transfer case shift motor replacement NHTSA’s full summary ↓

Stellantis filed this with NHTSA as a service bulletin dated Sep 6, 2024, about the power train. It names 15 model years across Jeep and Ram (2019–2025). 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.

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 database

Owners of the 15 model years this bulletin names have filed 4,758 complaints with NHTSA since 2015. 579 of them name Power Train — 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 2019 Ram 1500, the 75 owners who gave an odometer reading for Power Train reported it at a median of 15,000 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 Jeep Grand Wagoneer. The contact stated while driving approximately 52 MPH, the cruise control inadvertently disengaged and the vehicle was unable to accelerate as needed. There was an unknown warning light illuminated, and a message to service the vehicle was displayed. The vehicle was not diagnosed or repaired.

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 579.5

Is Stellantis 9100409 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 9100409 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 9100409 cover?

The manufacturer filed it against 15 model years across 2 brands (Jeep and Ram): 2025 Jeep Grand Wagoneer, 2024 Jeep Grand Wagoneer, 2023 Jeep Grand Wagoneer, 2022 Jeep Grand Wagoneer, 2025 Jeep 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.
