Honda bulletin A21-014
What it saysAmerican Honda is extending the warranty on the A/C condenser to 10 years from the original date of purchase with unlimited miles. NHTSA’s full summary ↓
Honda filed this with NHTSA as a service bulletin dated Jun 19, 2024, received Jun 3, 2021, about the visibility/wiper — 2 documents under this number. It names 5 model years (2017–2021). 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 communicationService Bulletin - American Honda is extending the warranty on the A/C condenser to 10 years from the original date of purchase with unlimited miles. This warranty extension only covers vehicles that have a defective A/C condenser from the factory. The A/C condenser was not manufactured to specification. As a result, corrosion may develop in the form of tiny holes in the condenser tube walls that allow the refrigerant to leak out. This does not apply to any vehicle that has a leaking condenser due to foreign object damage. It also does not apply to any vehicle that has ever been declared a total loss or sold for salvage by a financial institution or insurer, or has a branded or similar title under any state's law.
One of the 429 warranty extensions and special-coverage programs on file — every make, with the term each runs to.

Read by machine from the document NHTSA serves (10 pages), read Oct 4, 2026. A part number is shown only where it matches Honda’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. 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 5 model years this bulletin names have filed 2,216 complaints with NHTSA since 2015. 40 of them name Visibility/Wiper — 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.
On the 2017 Honda Civic, the 25 owners who gave an odometer reading for Visibility/Wiper reported it at a median of 21,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Since I have purchased my vehicle back in 2017 everything was running smooth with the A/C until one day one side of my center air vents was blowing hot air when the A/C was turned on. Then I kept hearing a hissing sound (like gasses escaping or boiling water) coming from the bottom of my dash on the front passenger side.

Evaporator failed at 63,000 miles, resulting in poor window defogging during morning hours. The failed evaporator also led to loss of cabin cooling resulting in excessive heat stress during daytime operation. Additionally the flammable R-1234yf refrigerant leaked into my cabin creating a fire risk.

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
Source: NHTSA, 49 CFR 579.5Is Honda A21-014 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 A21-014 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. Every Honda warranty extension on file lists the ones Honda has filed.
Which vehicles does A21-014 cover?
The manufacturer filed it against 5 model years: 2021 Honda Civic, 2020 Honda Civic, 2019 Honda Civic, 2018 Honda Civic, 2017 Honda Civic. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
