What it saysHose- Oil Cooler Inlet, Outlet NHTSA’s full summary ↓
Stellantis filed this with NHTSA as a service bulletin dated Dec 2, 2025, received Dec 11, 2025, about the engine. It names 14 model years across Jeep and Dodge (2018–2026). 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 14 model years this bulletin names have filed 3,248 complaints with NHTSA since 2015. 517 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 Grand Cherokee, the 52 owners who gave an odometer reading for Engine reported it at a median of 25,000 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 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 · ODI 11649967
While driving on the road the engine shuts completely off right in the middle of traffic which is extremely dangerous!!!...message displays on the screen where the speedometer is "shift to p to start". It has happened 3x yesterday and about a week ago once. Took to Jeep dealer yesterday and they are still investigating the issue
2018 Jeep Grand Cherokee · Engine · filed with NHTSA Jul 13, 2018 · ODI 11111104
I tell the dealership mechanics that this car does not turn on and they keep giving me the car back and now the car completely turns off while driving making this extremely dangerous and deadly situation. My fear is something happening to me or my kids while I’m 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 108840 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 108840 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 108840 cover?
The manufacturer filed it against 14 model years across 2 brands (Jeep and Dodge): 2026 Dodge Durango, 2025 Dodge Durango, 2024 Dodge Durango, 2023 Dodge Durango, 2022 Dodge Durango, 2021 Dodge Durango and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
