Honda bulletin A19-006
Honda filed this with NHTSA as a service bulletin dated Apr 6, 2020, received Feb 10, 2019, about the electrical system — 4 documents under this number. It names 2 model years (2017–2018). 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.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communication"Service bulletin - The telematics system is reporting deterioration of the fuel cell stack. This deterioration can reduce fuel cell output. Water improperly discharged inside the fuel cell stack mixes with hydrogen and oxygen, generating hydrogen peroxide. The hydrogen peroxide/water combination concentrates in one area, accelerating the deterioration of the electrolyte membrane in the fuel cell."

Common questions
Source: NHTSA, 49 CFR 579.5Is Honda A19-006 a recall?
No. A service bulletin 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 A19-006 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does A19-006 cover?
The manufacturer filed it against 2 model years: 2018 Honda Clarity, 2017 Honda Clarity. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
