Quoting the number at a service desk can save a diagnosis.

What owners reported
Source: NHTSA complaint databaseOwners of the 23 model years this bulletin names have filed 8,082 complaints with NHTSA since 2015. 2,345 of them name Electrical System, Service Brakes — 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 Wrangler, the 88 owners who gave an odometer reading for Electrical System reported it at a median of 18,570 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

Common questions
Source: NHTSA, 49 CFR 579.5Is Stellantis 9004433 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 9004433 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 9004433 cover?
The manufacturer filed it against 23 model years across 3 brands (Jeep, Ram and Dodge): 2023 Dodge Durango, 2022 Dodge Durango, 2022 Jeep Grand Cherokee, 2021 Jeep Grand Cherokee, 2023 Jeep Wrangler, 2022 Jeep Wrangler and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
