What owners reported
Source: NHTSA complaint databaseOwners of the 4 model years this bulletin names have filed 97 complaints with NHTSA since 2015. 12 of them name Electrical System — 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.
While driving through an active intersection, the vehicle experienced a sudden and complete loss of electrical power. The engine shut off without warning and all electrical systems immediately went dead. The instrument cluster went dark, the ignition was unresponsive, and the hazard lights did not function.

This is a follow-up to my earlier complaint about the same vehicle, a 2023 Acura RDX A-Spec Advance. In August 2026 the vehicle was stolen from a public street after offenders broke through the exterior driver’s door handle, reached the wiring behind it, and lowered the window to get inside.

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 F.1.4.1 a recall?
No. A over-the-air update 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 F.1.4.1 repair free?
A over-the-air update is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does F.1.4.1 cover?
The manufacturer filed it against 4 model years: 2025 Acura RDX, 2024 Acura RDX, 2023 Acura RDX, 2022 Acura RDX. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
