Stellantis bulletin 21-048-24

What it says"Transfer Case Active Shift Motor Replacement Customers must experience a Malfunction Indicator Lamp (MIL) illumination and the vehicle must exhibit/set one or more of the following Diagnostic Trouble Codes (DTCs)… NHTSA’s full summary ↓

Stellantis filed this with NHTSA as a service bulletin dated Aug 30, 2024, received Sep 4, 2024, about the power train. It names 9 model years across Jeep and Ram (2022–2024). 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.

Read by machine from the document NHTSA serves (2 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. 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 database

Owners of the 9 model years this bulletin names have filed 1,495 complaints with NHTSA since 2015. 212 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 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.

Common questions

Source: NHTSA, 49 CFR 579.5

Is Stellantis 21-048-24 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 21-048-24 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 21-048-24 cover?

The manufacturer filed it against 9 model years across 2 brands (Jeep and Ram): 2024 Jeep Grand Wagoneer, 2023 Jeep Grand Wagoneer, 2022 Jeep Grand Wagoneer, 2024 Jeep Wagoneer, 2023 Jeep Wagoneer, 2022 Jeep Wagoneer and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
