What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 964 complaints with NHTSA since 2015. 543 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 2021 Jeep Wrangler, the 34 owners who gave an odometer reading for Electrical System reported it at a median of 29,400 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 Jeep 0817823 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 0817823 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 0817823 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.
