Read by machine from the document NHTSA serves (2 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.
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.

Parasitic battery problem My car battery keeps dying on my Subaru sti 2020 after one day of not driving. I have had the car checked with Subaru dealership and a local shop but no issues were found. This morning I had to get my car jumped again after not driving it for one day. This battery was purchased brand new on nov 2024.
2020 Subaru WRX · Electrical System · filed with NHTSA Jan 7, 2025 · ODI 11634545
Unknown. I am unsure of the issue. However, there is an issue. & it is very dangerous... This has happend about 5, or 6 times now. Sometimes when I am making a turn (I believe it is related to the braking), My steering wheel locks up (as if the key isn't in the ignition). It only lasts for a second, or two.
2018 Subaru WRX · Steering · filed with NHTSA Sep 19, 2022 · ODI 11485364
I'm driving down the road and unexpectedly the power steering completely goes out and the car is almost impossible to steer. When I shut the car off it usually resets sometimes for only a couple seconds, sometimes longer before the power steering fails again.

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 4-30-25 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 4-30-25 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 4-30-25 cover?
The manufacturer filed it against 4 model years: 2021 Subaru WRX, 2020 Subaru WRX, 2019 Subaru WRX, 2018 Subaru WRX. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
