Stellantis bulletin 112639
Stellantis filed this with NHTSA as a service bulletin dated Jun 30, 2026, received Jul 8, 2026, about the engine. It names 33 model years across Jeep, Dodge and Alfa Romeo (2019–2026). 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 31 model years this bulletin names have filed 7,953 complaints with NHTSA since 2015. 2,055 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.
The contact owns a 2021 Jeep Wrangler 4XE. The contact stated while driving at an undisclosed, the check engine warning light illuminated. The accelerator pedal was depressed, but the vehicle failed to accelerate as intended, hesitated and jerked. The vehicle was taken to the dealer however, the failure could not be duplicated.
2021 Jeep Wrangler · Engine · filed with NHTSA Nov 24, 2025 · ODI 11701300
The auto start/stop feature in my car is not reliable. There have been three instances when i've been stopped at a light, I take my foot off the brake, the system activates start, and then as soon as I hit the gas, my car stalls. I then have to put my car in park, turn the vehicle off completely, and start it again.
2019 Jeep Compass · Engine · filed with NHTSA Aug 5, 2019 · ODI 11241878
My 23 Jeep Compass engine light came on and it started running rough. Dealer says part of the exhaust valve came off and damaged the piston. Now it needs a new motor. I just purchased it in April 2023. It is now 12/12/23 and I took it to the dealer 11/11/23. This potentially could have happened while I was driving.

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 112639 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 112639 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 112639 cover?
The manufacturer filed it against 33 model years across 3 brands (Jeep, Dodge and Alfa Romeo): 2026 Alfa Romeo Tonale, 2025 Alfa Romeo Tonale, 2024 Alfa Romeo Tonale, 2023 Alfa Romeo Tonale eAWD, 2025 Dodge Hornet, 2024 Dodge Hornet and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
