Acura bulletin Defect Code 6T6,
Acura filed this with NHTSA as a service bulletin dated Jun 15, 2022, received Jul 7, 2022, about the electrical system. It names 5 model years (2016–2020). A service bulletin 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.
