Stellantis filed this with NHTSA as a service bulletin dated Mar 21, 2026, received Mar 25, 2026, about the engine — 2 documents under this number. It names 124 model years across Jeep, Ram, Dodge and Chrysler (2016–2026). 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 (3 pages), read Sep 29, 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 104 model years this bulletin names have filed 23,068 complaints with NHTSA since 2015. 5,207 of them name Engine — 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 Jeep Cherokee, the 272 owners who gave an odometer reading for Engine reported it at a median of 18,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
While driving at highway speed the vehicle flashed a vehicle and I’ll shut down sign. A red turtle flashed and the vehicle began to decelerate. Had to pull over to a less than safe sand shoulder. Had highway speed traffic directly behind me. Dealership pulled codes related to the transmission. No previous issues or sign thereof. 25k miles

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 18-044-26 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 18-044-26 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 18-044-26 cover?
The manufacturer filed it against 124 model years across 4 brands (Jeep, Ram, Dodge and Chrysler): 2023 Chrysler 300, 2022 Chrysler 300, 2021 Chrysler 300, 2020 Chrysler 300, 2019 Chrysler 300, 2026 Chrysler Pacifica and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
