Read by machine from the document NHTSA serves (19 pages), read Sep 30, 2026. A part number is shown only where it matches Subaru’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 7 model years this bulletin names have filed 360 complaints with NHTSA since 2015. 26 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.

2024 Subaru Legacy · Electrical System · filed with NHTSA Oct 11, 2024 · ODI 11619239
The infotainment system and Apple CarPlay connectivity is posing a safety hazard. When I’m on a phone call my audio will randomly cut out and suddenly the person on the other side of the call can no longer hear me. In order to fix the issue I must pick up my phone while I’m driving to disconnect from Apple CarPlay and reconnect.
2024 Subaru Crosstrek · Electrical System · filed with NHTSA May 9, 2024 · ODI 11587897
In my new 2024 Ascent, there's a vibration in the driver side mirror that gets worse as speed increases. It's a minor issue, but it's disappointing for a brand new car to have this problem. The Subaru dealer hasn't taken any action despite being informed about it, and the vibration persists

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 Subaru 15-313-23 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 15-313-23 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 Subaru warranty extension on file lists the ones Subaru has filed.
Which vehicles does 15-313-23 cover?
The manufacturer filed it against 7 model years: 2024 Subaru Ascent, 2024 Subaru BRZ, 2024 Subaru Crosstrek, 2024 Subaru Forester, 2024 Subaru Impreza, 2024 Subaru Legacy and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
