2019 Honda Civic

The air conditioner compressor failed on my car at about 85,000 miles. My mechanic told me that they are noticing many 2019-2022 Honda Civics with the exact same problem, with the A/C compressor failing at about the same mileage. My mechanic replaced the compressor with a new Honda compressor. The cost was about $2,700. I've attached the invoice. The failure of the A/C compressor is a threat to safety for the following reasons: Loss of Windshield Defrosting: If the windows fogged up and I could not clear them because the AC failed, this blocks my vision and is a direct safety hazard. Engine Stalling or Serpentine Belt Failure: If the compressor locked up (seized) and broke my car's belt, it could cause me to lose power steering, battery charging, or engine cooling while driving. Extreme Heat Risk: If the AC failed in extreme summer heat (which is exactly what happened to me - it failed in July and I was without A/C for more than 6 weeks in the summer) it would put vulnerable passengers (like children or elderly family members) at risk for their health. Given the testimony of my mechanic that this same failure is happening to many Civic owners (2019-2022) at about the same engine age, I'd like it considered whether a recall is appropriate.

Honda Civics have a known Air Conditioning issues with an extended 10 year warranty on some parts including the A/C compressor seal and A/C Condenser. Other parts that may fail as a result of these two parts failing are no covered by the extended warranty. The A/C system on my Honda Civic failed in 2025 and additionally again in 2026. In 2025 the compressor was the issue and the system was repaired. Due to strain on the system while parts were failing, the A/C system failed a second time in 2026. The additional parts that may fail as a result to strain on the system while known parts are failing are not covered under Honda’s extended warranty or a recall. In 2026, I was told my compressor had failed. The compressor had failed from being overworked from leaked Freon in the system due to parts that failed that were covered under the warranty. This sort of repair should be covered by Honda and they should be held responsible for parts failing due to the known manufacturing issues. Failed A/C systems and downstream parts can pose safety risks during driving scenarios where windows need to be defogged or during heat waves that occur in warmer climates in the summer. If a part is failing due to strain from a part that has a known failure, it should be included in the warranty or a new recall by Honda.

AC unit blows hot air only on the left side. Temp in IL is over 90 degrees F. Yes, it has been confirmed by the dealer, but they are saying they are not liable if I pay for them to conduct the service and they cannot fix it. No, but the manufacturer had issues with the a/c compressor and condenser and for this specific 2019 Honda Civic. Those were recently replaced, but now I am still having A/C issues. No warnings. It appeared June 9th. My husband and I bought the same exact vehicle at the same exact location on the same exact date and BOTH vehicles are having this same exact issue only one week apart. Mine occurred on 6/9/2026 and his first occurrence started 7/12/2026.

In June 2026, the HVAC system in my 2019 Honda Civic 2.0L failed because the evaporator core developed a premature leak or crack. AutoNation Honda O’Hare inspected the vehicle and diagnosed the evaporator core as the failed component. The vehicle is available for inspection upon request. This failure creates a serious visibility hazard. During rain and humid conditions, the windshield and side windows fog rapidly. Because the air-conditioning system can no longer adequately remove moisture from the cabin air, the defrost and defog functions do not clear the glass effectively. This can severely obstruct my view of the road, nearby vehicles, pedestrians, and other hazards while driving. I have also noticed a persistent chemical odor coming from the vents. Because the evaporator core is located inside the HVAC housing, I am concerned that refrigerant, compressor oil, or other HVAC residue may be entering the passenger compartment. This creates a potential exposure concern, especially when the vehicle is operated with the windows closed. I received no specific dashboard warning that the evaporator core was failing. The first noticeable symptoms were reduced cooling, ineffective windshield defogging, and the chemical odor from the vents. Honda has extended warranty coverage for certain air-conditioning condenser and compressor failures affecting this generation of Civic, but it does not cover the evaporator core. I contacted Honda and requested goodwill assistance with the costly repair. Honda refused to provide any goodwill discount despite the known pattern of air-conditioning failures and the safety consequences of losing effective windshield dehumidification. I request that NHTSA investigate evaporator-core failures in 10th-generation Honda Civics and determine whether a safety recall or expanded manufacturer remedy is warranted.

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).

I am reporting a serious ongoing issue with my 2019 Honda Civic Sport involving the trunk repeatedly opening on its own both while driving and while parked. The issue is also causing the vehicle alarm to activate unexpectedly. The trunk has opened while the vehicle was in motion, creating a major safety concern. It also randomly opens while parked, sometimes triggering the alarm system for no apparent reason. The problem appears to happen intermittently but has become frequent enough that I no longer feel safe leaving the vehicle unattended or driving it normally. I attempted to clean the trunk latch area, but the issue continues. I believe there may be a malfunction involving the trunk latch, actuator, key fob system, electrical wiring, sensor, or alarm system. This situation is dangerous because the trunk can unexpectedly unlatch while driving, potentially blocking visibility or causing damage. The repeated alarm activations and trunk openings while parked are also causing concern about battery drain, security, and reliability. Vehicle Information: 2019 Honda Civic Sport Symptoms: • Trunk opens while driving • Trunk opens while parked • Alarm randomly activates • Trunk may not remain securely latched • Ongoing intermittent electrical or latch-related issue I am requesting that this issue be documented and inspected as soon as possible due to the safety risk involved.

I have had multiple problems with the AC on my 2019 Honda Civic now for some years. There have been leaks, issues of blowing hot air, replacing of parts, etc. The evaporator was replaced before (warranty extension) and then eventually the Freon 1234 leaked out. I've been told the expansion valve was leaking by one shop, and another tells me the evaporator core has a leak. The dealer wants $2,800 to replace the evap core and recharge the system. This is all maddening. I'm asking if the compressor shaft seals are OK (they say they are, but who knows for how long) per the Honda warranty extension issued. I used to have a 2006 civic and the AC worked FLAWLESSLY for 16 years! What's up here?????
