Subaru bulletin 09-99-23R
What it saysThis bulletin addresses rare cases of engine surg or jolting when the operator releases the accelerator from half-throttle. NHTSA’s full summary ↓
Subaru filed this with NHTSA as a service bulletin dated Feb 5, 2024, received Mar 4, 2024, about the electrical system. It names 15 model years (2017–2023).

Quoting the number at a service desk can save a diagnosis.

What owners reported
Source: NHTSA complaint databaseOwners of the 15 model years this bulletin names have filed 4,799 complaints with NHTSA since 2015. 1,320 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.
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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Subaru 09-99-23R 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 09-99-23R 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 09-99-23R cover?
The manufacturer filed it against 15 model years: 2023 Subaru BRZ, 2022 Subaru Forester, 2021 Subaru Forester, 2020 Subaru Forester, 2019 Subaru Forester, 2018 Subaru Forester and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
