What it saysThis bulletin announces an inspection procedure for the Smart Rear View Mirror Assembly. NHTSA’s full summary ↓
Subaru filed this with NHTSA as a service bulletin dated Aug 31, 2026, received Sep 3, 2026, about the electrical system. It names 5 model years (2024–2025). 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.

Read by machine from the document NHTSA serves (9 pages), read Sep 29, 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 5 model years this bulletin names have filed 355 complaints with NHTSA since 2015. 46 of them name Electrical System — 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.
In my new 2024 Ascent, there's a vibration in the driver side mirror that gets worse as speed increases. It's a minor issue, but it's disappointing for a brand new car to have this problem. The Subaru dealer hasn't taken any action despite being informed about it, and the vibration persists
2024 Subaru Ascent · Electrical System · filed with NHTSA Jul 12, 2024 · ODI 11601636
On Sunday around 10:00 am I stopped to gas up my car while I was going to church with my baby in a car seat in the backseat. I closed the car door leaving my car keys and cell phone in the center console and as I went behind the car to gas up it unexpectedly locked.

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 15-342-26 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 15-342-26 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 15-342-26 cover?
The manufacturer filed it against 5 model years: 2025 Subaru Ascent, 2024 Subaru Ascent, 2025 Subaru Forester, 2025 Subaru Outback, 2024 Subaru Outback. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
