Acura bulletin BTI&04202026901
Acura filed this with NHTSA as a manufacturer communication dated Apr 20, 2026, received Apr 22, 2026, about the fuel/propulsion system. It names 3 model years (2024–2026). 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.
