What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 12 complaints with NHTSA since 2015. 3 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.
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 Alfa Romeo 0823623 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 0823623 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 0823623 cover?
The manufacturer filed it against 1 model year: 2024 Alfa Romeo Tonale. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
