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.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as NHTSA’s summary states it — build dates and equipment as the manufacturer filed them. The dealer checks the VIN and the build date on the door jamb; a vehicle outside the window is not covered by this bulletin.
Data collection required for all 2020-2026MY vehicles with 3.6L PSU engines during any of their first 3 engine oil changes. This data collection is applicable to all vehicle with engines with sales codes: ERG, ERC, EH3 and ERF. To assist with monitoring and quality improvement of the 3.6L engine, every time a vehicle comes for any of the first 3 oil changes, please use wiTECH to record the total engine idle time and the total engine runtime. 1. Prior to perform the oil change connect wiTECH diagnostic tool. 2. Navigate to the topology screen on the action item section. 3. Once the topology screen loads, disconnect wiTECH and continue with oil change.

What owners reported
Source: NHTSA complaint databaseOwners of the 52 model years this bulletin names have filed 10,489 complaints with NHTSA since 2015. 2,852 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 2024 Jeep Wrangler, the 57 owners who gave an odometer reading for Engine reported it at a median of 15,000 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
2023 Chrysler Pacifica · Engine · filed with NHTSA Apr 3, 2025 · ODI 11652655
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.

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 9100670 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 9100670 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 9100670 cover?
The manufacturer filed it against 52 model years across 4 brands (Jeep, Ram, Dodge and Chrysler): 2026 Chrysler Pacifica, 2025 Chrysler Pacifica, 2024 Chrysler Pacifica, 2023 Chrysler Pacifica, 2022 Chrysler Pacifica, 2021 Chrysler Pacifica and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
