What it saysOwner Notification Letter - Under certain circumstances, the torque converter lock-up clutch cannot provide adequate holding force due to pressure bleeding down through a crack in the lock-up piston. NHTSA’s full summary ↓
Acura filed this with NHTSA as a manufacturer communication dated Jun 4, 2025, received Jul 1, 2025, about the power train. It names 2 model years (2017–2018). A manufacturer communication is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

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 2 model years this bulletin names have filed 158 complaints with NHTSA since 2015. 37 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.
This is a history of getting work done on my car, the transmission hesitates and shifts very hard into the next gear, a software update was done to correct the issues and after 1100 miles it was back.
