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 72 model years this bulletin names have filed 12,606 complaints with NHTSA since 2015. 167 of them name Service Brakes — 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 2016 Subaru Forester, the 19 owners who gave an odometer reading for Service Brakes reported it at a median of 32,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Brake making squeaky noise when it's being applied. This happened less than 30,000 miles during April 2023. I went to dealership during a routine oil change and the service tech found nothing wrong. I took it to road trip and it was to the point where the vehicle shakes and everyone else around me could hear it when we apply the brake.
2022 Subaru Ascent · Service Brakes · filed with NHTSA Nov 23, 2023
My son moved my car onto the driveway, stopped it with the foot brake with the manual transmission in neutral. The hill assist was activated, so when he got out of the car the brake held long enough for him to get out of the car and walk away before the brake released, about 2 seconds. The car then rolled down the driveway into a tree.

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 06-90-24 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 06-90-24 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.
Which vehicles does 06-90-24 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.
