Stellantis bulletin 112842
Stellantis filed this with NHTSA as a service bulletin dated Jun 18, 2026, received Jul 2, 2026, about the engine. It names 56 model years across Jeep and Alfa Romeo (2017–2026). 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.

What owners reported
Source: NHTSA complaint databaseOwners of the 55 model years this bulletin names have filed 11,732 complaints with NHTSA since 2015. 2,848 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.
Alfa Romeo USA is in my opinion hiding a constant problem they have with stelvios. The oil turbo line has a faulty oring and leaks oil onto engine which causes smoke that can not be healthy to breathe in. I have talked to severa Alfa dealers in service depts and they confirm to me that they have fixed numerous stelvios with this problem.
2018 Alfa Romeo Stelvio · Engine · filed with NHTSA Feb 17, 2021 · ODI 11396594
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.

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 112842 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 112842 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 112842 cover?
The manufacturer filed it against 56 model years across 2 brands (Jeep and Alfa Romeo): 2026 Alfa Romeo Giulia, 2025 Alfa Romeo Giulia, 2024 Alfa Romeo Giulia, 2023 Alfa Romeo Giulia, 2022 Alfa Romeo Giulia, 2021 Alfa Romeo Giulia and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
