Read by machine from the document NHTSA serves (18 pages), read Oct 4, 2026. A part number is shown only where it matches Acura’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.

My TLX Tech 2023 lost complete power while I pulled up to a busy intersection on a dark and rainy day. As a puled to stop and my idle stop enabled the car was fine. Once I tried to accelerate the car immediately went into Park from Drive. All of the controls started to blink and the car powered down like a computer system who was on 0%.

We have a 2022 Acura TLX Type S and it has started to show an errors - Adaptive Damper System Problem. From what I can gather from reviewing articles on the Internet is that this problem is caused because of poor wiring design by Honda / Acura, which is causing speed sensors electronics to erode.

Common questions
Source: NHTSA, 49 CFR 579.5Is Acura B23-030 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 B23-030 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 B23-030 cover?
The manufacturer filed it against 3 model years: 2023 Acura TLX, 2022 Acura TLX, 2021 Acura TLX. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
