Read by machine from the document NHTSA serves (3 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.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 33 model years this bulletin names have filed 5,446 complaints with NHTSA since 2015. 1,435 of them name Electrical System, Engine — 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.
On the 2020 Subaru Outback, the 115 owners who gave an odometer reading for Electrical System reported it at a median of 5,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

2024 Subaru Legacy · Electrical System · filed with NHTSA Oct 11, 2024
At around the 2000 mile mark I noticed a drastic reduction in fuel econemy. I also started noticing metal particles in the engine oil. I also noticed a significant drop in engine power as well. This is a sign of debris getting in the engine and causing metal particles to become broken off. My mileage went from 460-480 mpt to 360-380 mpt.

The contact owns a 2019 Subaru Forester. While turning the vehicle, the entire electrical system shut off, including the power steering and emergency braking system. The contact was almost involved in a crash due to the failure. The contact pulled over, shut off the engine, and restarted the vehicle, but the electrical failures remained.
2019 Subaru Forester · Electrical System · filed with NHTSA Mar 25, 2019
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 09-115-24R 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 09-115-24R 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.
Which vehicles does 09-115-24R cover?
The manufacturer filed it against 33 model years: 2023 Subaru BRZ, 2022 Subaru BRZ, 2024 Subaru Crosstrek, 2023 Subaru Crosstrek, 2022 Subaru Crosstrek, 2021 Subaru Crosstrek and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
