Read by machine from the document NHTSA serves (4 pages), read Sep 30, 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.

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 8 model years this bulletin names have filed 3,104 complaints with NHTSA since 2015. 321 of them name 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 2019 Subaru Forester, the 23 owners who gave an odometer reading for Engine reported it at a median of 30,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
I was crossing two lanes of a very busy ocean front street when the engine “bogged down” . I let off on the gas pedal and then depressed it again, which then caused the engine to go off. I the quickly restarted the engine and was able to get out of the way of oncoming traffic.

Vehicle: 2021 Subaru Legacy Base 2.5i Mileage:~65,000 miles My engine suddenly began making loud internal knocking/tapping noises with no warning lights, no overheating, and no prior symptoms. The vehicle immediately became unsafe to operate.
2021 Subaru Legacy · Engine · filed with NHTSA Jun 4, 2026
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 09-80-21R 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 09-80-21R 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 09-80-21R cover?
The manufacturer filed it against 8 model years: 2021 Subaru Crosstrek, 2021 Subaru Forester, 2020 Subaru Forester, 2019 Subaru Forester, 2021 Subaru Legacy, 2020 Subaru Legacy and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
