Read by machine from the document NHTSA serves (4 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.

What owners reported
Source: NHTSA complaint databaseOwners of the 8 model years this bulletin names have filed 1,105 complaints with NHTSA since 2015. 303 of them name Engine, Power Train — 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 Acura RDX, the 50 owners who gave an odometer reading for Engine reported it at a median of 8,300 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
I would like to report a serious safety issue with the 2021 Acura TLX Type s. Recently in April 2024, while driving, I heard a loud pop from the vehicle, and it turned out that the transfer case had burst into the transmission. This failure has rendered the rear-wheel drive non-functional, resulting in severe oversteer.
2021 Acura TLX · Engine · filed with NHTSA Nov 9, 2024
A couple of days ago, onapril 19th, my wife and I were driving throughcolumbus, ga. It was around 7:00 AM and raining. We had been driving about 1 1/2 hours andwe were only going around30 MPH when I accelerated to pass a dump truck. The 2019 Rdx (6000 miles) started accelerating and then lost all power.
2019 Acura RDX · Engine · filed with NHTSA Apr 21, 2019
Vehicle loses almost all engine power under hard acceleration. This fault requires you to stop the vehicle and restart to continue. Engine light flashes yellow. The first time this occurred was at highway speed in a passing situation. The second time was during a freeway merge.
2019 Acura RDX · Power Train · filed with NHTSA Apr 22, 2019
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 Acura B23-010 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 B23-010 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 B23-010 cover?
The manufacturer filed it against 8 model years: 2023 Acura RDX, 2022 Acura RDX, 2021 Acura RDX, 2020 Acura RDX, 2019 Acura RDX, 2023 Acura TLX and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
