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.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Subaru 15-315-23R 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 15-315-23R 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 15-315-23R cover?
The manufacturer filed it against 6 model years: 2023 Subaru Ascent, 2024 Subaru Crosstrek, 2024 Subaru Legacy, 2023 Subaru Legacy, 2024 Subaru Outback, 2023 Subaru Outback. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
