What the bulletin says

The front brakes stop squealing when they are warmed up. For the front brakes, the brake damping force of applied shims is insufficient at colder temperature. For the rear brakes, there is not enough dampening between the rear brake pads and shims.

Read by machine from the document NHTSA serves (3 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 6 model years this bulletin names have filed 977 complaints with NHTSA since 2015. 23 of them name Service Brakes — 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 2020 Acura RDX, the 20 owners who gave an odometer reading for Service Brakes reported it at a median of 1,860 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

Front brakes make noise and you can feel the abrasive rubbing. I have had both the brake pads and rotors replaced ar approx 2500 miles only to have the symptom reoccurrence about 500 miles later. Dealer says a ticket has been opened with Acura to remanufacture brake pads but I have not had an update in over two months I think.

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.
Quote the number at the service desk. It is what the dealer’s system is keyed on.

Common questions
Source: NHTSA, 49 CFR 579.5Is Acura B19-053 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 B19-053 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 B19-053 cover?
The manufacturer filed it against 6 model years: 2024 Acura RDX, 2023 Acura RDX, 2022 Acura RDX, 2021 Acura RDX, 2020 Acura RDX, 2019 Acura RDX. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
