Stellantis filed this with NHTSA as a service campaign dated Aug 1, 2026, received Aug 6, 2026, about the power train — 1 document under this number: 79D Combo. It names 2 model years across Jeep and Dodge (2024). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.

Read by machine from the document NHTSA serves (8 pages), 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.
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 2 model years this bulletin names have filed 122 complaints with NHTSA since 2015. 29 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 2024 Jeep Wagoneer S. The contact stated that while the vehicle was parked, the vehicle unexpectedly shifted to reverse(R) and rolled backwards unintendedly at approximately 10 MPH. The brake pedal was pumped several times to stop the vehicle.
2024 Jeep Wagoneer · Power Train · filed with NHTSA Jul 2, 2026 · ODI 11748043
Car was 1.5 weeks old, purchased brand new. Had several electrical glitches in the days prior, which went away. Pulled into my son's Little League game, and the car just started flashing all lights on the dash, then said 'Service Transmission'.
2024 Dodge Charger · Power Train · filed with NHTSA Aug 9, 2025 · ODI 11679522
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 79D a recall?
No. A service campaign 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 79D repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does 79D cover?
The manufacturer filed it against 2 model years across 2 brands (Jeep and Dodge): 2024 Dodge Charger, 2024 Jeep Wagoneer. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
