Stellantis filed this with NHTSA as a service bulletin dated Dec 10, 2025, received Dec 17, 2025, about the electrical system. It names 12 model years across Jeep and Dodge (2018–2025). 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.

Read by machine from the document NHTSA serves (2 pages), read Sep 30, 2026. A part number is shown only where it matches Stellantis’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 12 model years this bulletin names have filed 2,697 complaints with NHTSA since 2015. 841 of them name Electrical System — 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 82 owners who gave an odometer reading for Electrical System reported it at a median of 29,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The start/stop warning light came on for the second time on my 2019 Durango. I had both batteries replaced the first time and now, at 18,500 miles it came on again even though I drive it daily on both highway and local roads. This time, the warning only came on once but the start/stop feature was affecting the performance of the truck.

While drive my 2018 Dodge Durango on the fwy around 65+ the engine just turn off. With kids in the car we were stuck in the slow lane of the fwy unable to move the car. I tried restarting it with no luck. The car still had power(lights were on). The car wouldn't go into neutral .. The car had to be pulled off the road by a tow truck.
2018 Dodge Durango · Electrical System · filed with NHTSA Apr 1, 2019
My vehicle was purchased brand new 11/2018, when I press the button to start it, 75% of the time it won't start and takes several attempts. Also when I shift into reverse, the r just flashes and the vehicle won't reverse. It won't move until I turn it off and restart it again. These two problems occur frequently
2018 Jeep Grand Cherokee · Electrical System · filed with NHTSA Jun 12, 2018
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 08-396-25 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 08-396-25 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.
Which vehicles does 08-396-25 cover?
The manufacturer filed it against 12 model years across 2 brands (Jeep and Dodge): 2025 Dodge Durango, 2024 Dodge Durango, 2023 Dodge Durango, 2022 Dodge Durango, 2021 Dodge Durango, 2020 Dodge Durango and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
