What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 15 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.
For over 12 months since October 2025, the vehicle has intermittently (and progressively more regularly) thrown multiple, concurrent dash warnings/error messages for multiple vehicle functions, followed typically by (and without driver input) shifting the vehicle automatically into Neutral or Park while on and in gear.

Common questions
Source: NHTSA, 49 CFR 579.5Is Alfa Romeo 0820523 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 0820523 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 0820523 cover?
The manufacturer filed it against 2 model years: 2022 Alfa Romeo Stelvio, 2021 Alfa Romeo Stelvio. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
