Honda filed this with NHTSA as a manufacturer communication dated Jun 4, 2025, received Jul 1, 2025, about the power train. It names 1 model year (2017).

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 39 complaints with NHTSA since 2015. 7 of them name 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.
I own a 2017 Honda Odyssey that is currently covered under an extended warranty related to the torque converter, specifically addressing Diagnostic Trouble Code (DTC) P0741. I experienced symptoms twice—once in January 2025 and again in May 2025—using an OBD-II scanner.

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

No. A manufacturer communication 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.

Is the ONL6T806032025 Odyssey Le repair free?
