Stellantis filed this with NHTSA as a service bulletin dated Oct 2, 2025, received Oct 8, 2025, about the power train. It names 45 model years across Jeep, Ram, Chrysler and Fiat (2016–2025). 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.

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 45 model years this bulletin names have filed 7,316 complaints with NHTSA since 2015. 1,553 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 2017 Chrysler Pacifica, the 302 owners who gave an odometer reading for Power Train reported it at a median of 27,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
So I have a 2020 Renegade Sport. Had no issues with it up to today but I was climbing the gravel hill to my house in about 4 inches of snow. I was in 4WD snow mode and lost everything. Error messages popped and got kicked into FWD. Jeep went sliding, luckily I slid into the upward side of the hill and not over the edge. Got these errors.

I have a 2019 jeep renegade. I have had issues with the vehicle not wanting to shift when it is cold and after it has been driven long periods of time. I have had the vehicle in several times an they keep saying there is nothing wrong. When I first got the vehicle before the first oil change they had to put a quart of oil in the vehicle.

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 21-040-25 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 21-040-25 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 21-040-25 cover?
The manufacturer filed it against 45 model years across 4 brands (Jeep, Ram, Chrysler and Fiat): 2017 Chrysler 200, 2016 Chrysler 200, 2025 Chrysler Pacifica, 2024 Chrysler Pacifica, 2023 Chrysler Pacifica, 2022 Chrysler Pacifica and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: built on or before 1 Dec 2024 — the build date is on the certification label in the driver’s door jamb.
