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 20 model years this bulletin names have filed 3,232 complaints with NHTSA since 2015. 1,252 of them name Electrical System, Power Train, 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.

This is a brand new car no one buys a new car to add oil to it, then to get told by the dealership that it’s normal for up to (2Q) of oil to be added because it’s the only AWD boxer, but yet the…
2024 Subaru WRX · Engine · filed with NHTSA Mar 24, 2025 · ODI 11650068
I would just like to complain about the excess Rtv on the engine oil pan that has been demonstrated on numerous videos of people opening up the oil drain pan and finding chunks of Rtv blocking some of the engine oil pickup tube. I have not opened up my oil drain pan due to cost. This has not lead to failure as of yet but it is worrisome.

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 16-150-24R 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 16-150-24R 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. Every Subaru warranty extension on file lists the ones Subaru has filed.
Which vehicles does 16-150-24R cover?
The manufacturer filed it against 20 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.
