Subaru bulletin WRJ-23R
What it says(Subaru) has initiated a safety recall for certain 2023 model year Ascent vehicles that may be equipped with a front lower control arm with a loose castle nut. NHTSA’s full summary ↓
Subaru filed this with NHTSA as a service bulletin dated Jun 2, 2023, received Jul 3, 2023, about the suspension. It names 1 model year (2023). 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.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Subaru WRJ-23R 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 WRJ-23R 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 WRJ-23R cover?
The manufacturer filed it against 1 model year: 2023 Subaru Ascent. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: 2023 Ascent: built 31 Mar 2023 – 3 Apr 2023 — the build date is on the certification label in the driver’s door jamb.
