Read by machine from the document NHTSA serves (1 page), read Sep 30, 2026. A part number is shown only where it matches Stellantis’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 databaseOwners of the 12 model years this bulletin names have filed 1,129 complaints with NHTSA since 2015. 164 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.
The contact owns a 2026 Ram 1500. The contact stated that while driving at an undisclosed speed, the tow module independently switched from automatic drive to tow. The contact stated that the trailer tow module switched as if a trailer was being towed. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer.

Came to a stop sign, waited for traffic to clear to turn left as I floored it started moving and then all of a sudden loss acceleration and notice rpm ramped up to 7k. As in was just coasting I notice only my rpm would go up but the truck wouldn’t move. Lucky I coasted to the side of road and shifted to park.

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 9100672 Rev 1 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 9100672 Rev 1 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 9100672 Rev 1 cover?
The manufacturer filed it against 12 model years across 2 brands (Jeep and Ram): 2026 Jeep Grand Wagoneer, 2025 Jeep Grand Wagoneer, 2024 Jeep Grand Wagoneer, 2023 Jeep Grand Wagoneer, 2026 Jeep Wagoneer, 2025 Jeep Wagoneer and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
