What it saysThis Bulletin provides guidance for diagnosing a leaking front or rear suspension strut. NHTSA’s full summary ↓
Subaru filed this with NHTSA as a service bulletin dated Jul 8, 2024, received Aug 5, 2024, about the suspension. It names 73 model years (2016–2025). 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.

What owners reported
Source: NHTSA complaint databaseOwners of the 72 model years this bulletin names have filed 12,691 complaints with NHTSA since 2015. 9 of them name Suspension — 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.
Part 1 Today is January, 28, 2026 How it all started. My appointment was Tuesday, June 10th, 2025 at 10:15 am. During my last oil change, I was informed by Chris that an alignment would be needed to correct the rear passenger wheel showing -2.4 camber. I asked Chris could I go ahead and schedule the service repair now.

I purchased a brand new 2025 Subaru Forester Wilderness and immediately noticed a persistent vibration in the steering wheel, seat, and footwell area. The vibration is present at all times — while driving at various speeds and even while idling. It is very distracting and uncomfortable.

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 05-91-24 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 05-91-24 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 05-91-24 cover?
The manufacturer filed it against 73 model years: 2024 Subaru Ascent, 2023 Subaru Ascent, 2022 Subaru Ascent, 2021 Subaru Ascent, 2020 Subaru Ascent, 2019 Subaru Ascent and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
