Stellantis bulletin 9100624
What it saysVerify Reman part number availability. NHTSA’s full summary ↓
Stellantis filed this with NHTSA as a service bulletin dated Jul 8, 2025, received Jul 17, 2025, about the engine. It names 43 model years across Jeep, Ram 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.
One page for every brand it was filed under. Each brand’s bulletins: Jeep · Ram · Fiat.

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 41 model years this bulletin names have filed 9,520 complaints with NHTSA since 2015. 3,042 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 Jeep Compass, the 275 owners who gave an odometer reading for Engine reported it at a median of 20,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Engine oil and stalling. I went for my 2nd oil change 8/27/2018. The service tech and a mechanic listened when I said the oil was basically gone and my husband had to add 2 quarts. I even checked all the system warnings and there is none for low oil. When pulling out into an intersection the car totally shut off at 4 different times.

Common questions
Source: NHTSA, 49 CFR 579.5Is Stellantis 9100624 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 9100624 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 9100624 cover?
The manufacturer filed it against 43 model years across 3 brands (Jeep, Ram and Fiat): 2023 Fiat 500, 2022 Fiat 500, 2021 Fiat 500, 2020 Fiat 500, 2019 Fiat 500, 2018 Fiat 500 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
