A/C failure on other Civic years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2014, 2015, 2020, 2021, 2022, 2023, 2024, 2025, 2026.
What this problem usually is
Most A/C complaints start the same way: the fan still blows, but the air coming out of the vents is warm or only a little cool. Some owners get cold air that fades after a while, and others hear a noise from the compressor before it quits. It's rarely a safety problem on its own, which is also why it seldom gets a recall.
What got replaced
Owners who name the part that was replaced mention the condenser (19 reports), the compressor (17 reports) and the evaporator (16 reports).
Recalls and investigations
No recall on this problem covers the 2019 model year as of Oct 2, 2026.
What owners paid
7 of the 36 reports quote a price. Each dot is one quote. The middle half runs $1,500 to $2,800.
When it happens
The middle half of failures fell between 5,000 and 43,000 miles, from the 10 reports that gave a mileage.
Is this a known problem?
The manufacturer has sent NHTSA 8 service bulletins or notices for the 2019 Honda Civic that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.
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.
Due to supplier process concerns, the A/C compressor may not have been manufactured to specifications. As a result, abnormal wearing of the rubber seal may occur causing gaps in the compressor shaft to develop allowing refrigerant to leak out.
We have identified a potential concern with GUIDE, AC COMP SEAL 07AAG-5AAA100, which was a part of 6CVC SEAL REPLACEMENT KIT, 07AAC-5AAA1Z0 that was recently sent to all Honda dealers.
Customers have complained of the air conditioning system not blowing cold air due to the oil/refrigerant leak from the A/C compressor main shaft seal.

What owners wrote
“Honda dealership diagnosed my vehicle with an evaporator core leak. FOUND A/C SYSTEM PRESSURES LOW. FURTHER INSPECTION FOUND DARK SPOTS ON THE EVAPORATOR. A/C EVAPORATOR LEAKING. The evaporator core is suffering from the exact same chemical reactions to the R1234yf refrigerant that forced Honda to issue 10-year warranty extensions for the A/C condenser and compressor shaft seals (under TSB 19-091 and TSB A23-039).”

“The AC evaporator broke and only the AC condenser and sealer are under extended warranty. The AC evaporator is a costly repair and several other Honda owners have noted it has failed. Without the AC evaporator functioning, the AC system does not work.”

“Recall for A/C components was serviced. Less than a year later, Evaporator for A/C experiencing same issue. Dealership doesn't want to warranty, asking for $1500, even though evaporator experiencing same issue as recalled components. Online research finds this is extremely common.”

“The air conditioning system has a leak. There are a lot of complaints about it online and they already issued an extended warranty for Civic vehicles covering up to year 2018 for a leaking condenser. Right now I have no air conditioning.”

Should you keep driving it?
This page can't tell you that. 0 of 36 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
