Subaru bulletin 15-330-25
What it saysThis Service Bulletin is to inform you of a procedure to restore CP1.5’s normal operation by initializing the head unit. NHTSA’s full summary ↓
Subaru filed this with NHTSA as a service bulletin dated Oct 28, 2025, received Nov 4, 2025, about the electrical system. It names 15 model years (2023–2025). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

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.

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 15-330-25 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 15-330-25 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 15-330-25 cover?
The manufacturer filed it against 15 model years: 2025 Subaru Ascent, 2024 Subaru Ascent, 2023 Subaru Ascent, 2025 Subaru Crosstrek, 2024 Subaru Crosstrek, 2025 Subaru Forester and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
