What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationPUMP, Auxiliary Coolant Before replacing the Auxiliary Coolant Pump, please perform the following steps: 1) Key ON/OFF and let the after-run pump run for at least 20 minutes before moving on to step #2. 2) Inspect the pump connector area for presence of water. 3) Inspect the pump connector for corrosion. 4) Inspect the pump for coolant contamination as this can cause the pump to stall. 5) Inspect battery terminals for damage to rule out a battery drainage issue. 6) Ensure the PCM is up-to-date with the latest available flash. If correct repair is not performed then the claim or condition will be recovered by Warranty Operations.

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.

What owners reported
Source: NHTSA complaint databaseOwners of the 12 model years this bulletin names have filed 1,125 complaints with NHTSA since 2015. 891 of them name Electrical System, 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 2025 Ram 1500, the 27 owners who gave an odometer reading for Electrical System reported it at a median of 6,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
I am filing a safety defect complaint regarding a 2026 Dodge Charger Daytona (400V electric vehicle platform) that suffered a catastrophic high-voltage system shutdown at approximately 1,261 miles. The vehicle had charge remaining and was being prepared for charging when it experienced a forced EV system shutdown and would not restart.
2026 Dodge Charger · Electrical System · filed with NHTSA Feb 24, 2026 · ODI 11720267
As I was pulling up to a red light, the vehicle threw itself into park and completely stopped and would not move. I was unable to put gear into drive. Thankfully, I was not going at full speed. After a couple minutes, I was able to put my foot on brake to restart the car. At this point, the engine and battery light were on as well.

Common questions
Source: NHTSA, 49 CFR 579.5Is Stellantis 9100861 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 9100861 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 9100861 cover?
The manufacturer filed it against 12 model years across 3 brands (Jeep, Ram and Dodge): 2026 Dodge Charger, 2026 Jeep Grand Wagoneer, 2025 Jeep Grand Wagoneer, 2024 Jeep Grand Wagoneer, 2023 Jeep Grand Wagoneer, 2022 Jeep Grand Wagoneer and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
