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 4 model years this bulletin names have filed 20 complaints with NHTSA since 2015. 1 of them name Steering — 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.
The vehicle is equipped with 4 wheel steering. The rear wheels are controled by the computer. While maneuvering in a parking lot or after sharp turns the rear wheels do not respond to driver input. The wheels get stuck in the wrong direction and the driver must correct direction of travel to compensate.

Common questions
Source: NHTSA, 49 CFR 579.5Is Acura ONL6R508212023 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 ONL6R508212023 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 Honda warranty extension on file lists the ones Honda has filed.
Which vehicles does ONL6R508212023 cover?
The manufacturer filed it against 4 model years: 2019 Acura RLX, 2018 Acura RLX, 2017 Acura RLX, 2016 Acura RLX. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
