What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 947 complaints with NHTSA since 2015. 453 of them name Electrical System, Power Train — 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 2021 Jeep Wrangler, the 33 owners who gave an odometer reading for Electrical System reported it at a median of 26,000 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 received notification of NHTSA Campaign Number: 25V741000 (Electrical System); however, the part to do the recall repair was not yet available. The contact stated that the check engine warning light was illuminated.

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 Jeep 1807323 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 1807323 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 1807323 cover?
The manufacturer filed it against 1 model year: 2021 Jeep Wrangler. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
