Stellantis filed this with NHTSA as a service bulletin dated May 2, 2023, received Jul 31, 2023, about the engine. It names 29 model years across Jeep, Ram, Dodge and Chrysler (2018–2023). 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.

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 29 model years this bulletin names have filed 12,027 complaints with NHTSA since 2015. 2,717 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 2018 Chrysler Pacifica, the 167 owners who gave an odometer reading for Engine reported it at a median of 10,600 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
2023 Chrysler Pacifica · Engine · filed with NHTSA Apr 3, 2025
While driving on the highway, the engine overheating light came on, the car seemed to be losing power, and I pulled over and was then towed to the dealership. My safety was put at risk as I could have been hit as the car was slowing down in fast traffic; it also was extremely cold (about 5 degrees F) while I waited for the tow truck.
2022 Dodge Durango · Engine · filed with NHTSA Mar 23, 2025
The contact owns a 2020 Chrysler Pacifica Hybrid. The contact stated while driving 75 MPH, the vehicle stalled. The check engine warning light illuminated intermittently.

2020 Chrysler Pacifica · Engine · filed with NHTSA Mar 7, 2023
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 9100143 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 9100143 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.
Which vehicles does 9100143 cover?
The manufacturer filed it against 29 model years across 4 brands (Jeep, Ram, Dodge and Chrysler): 2023 Chrysler Pacifica, 2022 Chrysler Pacifica, 2021 Chrysler Pacifica, 2020 Chrysler Pacifica, 2019 Chrysler Pacifica, 2018 Chrysler Pacifica and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
